Objectives: A high prevalence of chronic hyperventilation syndrome in patients with asthma has been reported. We examined whether this phenomenon extended to allergy clinic patients in general and whether the prevalence was higher in patients attending a general allergy clinic compared with those attending a routine ENT clinic in our hospital.

Methods: We examined the prevalence of hyperventilation syndrome in unselected, consecutive patients (n = 100) seen in an allergy clinic. The validated Nijmegen questionnaire was completed by patients in the waiting room. We also administered the questionnaire to unselected, consecutive patients (n = 100) in a routine ENT clinic.

Results: There was no significant difference in prevalence of hyperventilation between allergy clinic and routine ENT clinic patients (25/100 vs 23/100).

Conclusion: The result indicates a high prevalence of hyperventilation amongst hospital attendees in general. Consideration should perhaps be given to the possible role of hyperventilation in symptomatology.

Cochlear implantation is a high cost, low volume intervention which is provided to adults and children with profound hearing impairment. Demand is increasing in the UK as a result of improved technology, changes in intervention criteria and the national newborn hearing screening programme. In order to inform commissioning policy for cochlear implantation in five English primary care trusts, we reviewed the evidence and assessed the complexities of developing needs and of service provision assessment and planning. Our results indicated that the current level of provision was well below what would be expected if the majority of people meeting current criteria were given a cochlear implant. Gaps between the clinical intervention thresholds and the level of service commissioned have widened. Long-term cost effectiveness and incidence studies are needed to assess cochlear implantation in the light of these lower clinical intervention thresholds.

The aim of this study was to evaluate the patient's experience of transnasal flexible laryngo-oesophagoscopy under local anaesthetic in an out-patient setting. This was a clinical observational study using a patient questionnaire and visual analogue score. Subjects were 50 patients seen in the hospital's ENT outpatient clinic between March and August 2004 in whom transnasal flexible laryngo-oesophagoscopy was performed and who completed pain discomfort questionnaires. Any patient undergoing transnasal flexible laryngo-oesophagoscopy, for either diagnostic or therapeutic purposes, was included in the study. Patients in whom transnasal flexible laryngo-oesophagoscopy was not necessary as part of their investigation or treatment were excluded. Patients completed a questionnaire, providing a simple visual analogue score for discomfort during the procedure. Any operative complications were noted by the surgeon. All patients completed transnasal flexible laryngo-oesophagoscopy, and the upper aerodigestive tract was clearly visualized. The procedure is well tolerated, with mean score of <  1 out of 10 for all forms of discomfort. There was a complication rate of 2 per cent (one patient with epistaxis); no other complications occurred. Transnasal flexible laryngo-oesophagoscopy is a new diagnostic and therapeutic technique which is well tolerated by patients. It compares favourably with other flexible endoscopic techniques. This report documents for the first time a detailed description of patients' experience of this technique.

Objective: To establish the frequency of occurrence of delayed facial nerve paralysis following tympano-mastoid surgery in our department and to determine the aetiological factors and long term prognosis.

Setting: Tertiary care academic centre.

Materials and methods: A retrospective review of all patients who had undergone tympano-mastoid surgery in our department over the previous five years was carried out. A total of 219 patients were included in the study. Only two patients were identified as having delayed onset facial nerve palsy over this period of time. The patients' medical records were reviewed and the patients clinically assessed.

Results: The frequency of delayed onset facial nerve palsy following tympano-mastoid surgery in our series was 0.91 per cent. Facial weakness set in on day eight and day 14 in the two patients. Serological investigations in both patients revealed raised titres of immunoglobulin (Ig) M and IgG to varicella-zoster virus, confirming the presence of varicella-zoster infection. In our experience, the combined use of prednisone and acyclovir was an effective form of treatment for both patients, whose facial nerve function fully recovered within six months of onset.

Conclusion: The incidence of delayed facial nerve palsy following tympano-mastoid surgery is low. It can occur up to two weeks after the surgery. Our two cases confirm viral reactivation to be an important aetiological factor in the development of delayed onset facial nerve palsy. The overall prognosis for delayed facial nerve palsy following tympano-mastoid surgery appears to be good.

Aims: Acute or subacute haemorrhage is one of the most frightening complications in patients suffering from advanced head and neck cancer. Few articles report experience with superselective endovascular therapy for this purpose. Is endovascular therapy underestimated in the field of palliative head and neck cancer therapy? This study set out to investigate this question.

Patients and methods: A review was undertaken of the clinical courses of seven patients (six men, one woman) suffering from incurable, advanced head and neck cancer (four pharyngeal, two laryngeal, one neck) and treated with superselective endovascular strategies as an emergency procedure for acute bleeding.

Results: All patients were successfully treated without evidence of neurological complication. Patients reached a median survival of 20 weeks (range eight–168 weeks). Following endovascular treatment all patients were discharged from the hospital within several days. Three patients survived almost free of symptoms for several weeks and were able to stay at home with their families until their death.

Conclusion: We conclude that in the field of palliative care, superselective endovascular therapy deserves to be considered alongside standard treatment options for the management of acute haemorrhage from advanced head and neck cancer.

Introduction: Otitis media with effusion (OME) is an inflammation of the middle ear in which a collection of liquid is present in the middle-ear space while the tympanic membrane is intact. The association between adenoid inflammation and OME has long been noted but the exact mechanism is still much debated. We studied the role of adenoid mast cells in the causation of OME.

Objective: To study the distribution and role of adenoid mast cells in the causation of OME

Methodology: A cross-sectional, prospective study was carried out in the otorhinolaryngologic clinic, department of otorhinolaryngology (ORL), Science University of Malaysia, from June 1999 to September 2001. A total number of 50 cases were studied. Twenty-five of these patients underwent adenoidectomy, while another 25 patients underwent adenoidectomy and myringotomy with ventilation tube insertion. The adenoid specimens from all patients were examined for the number of adenoid mast cells present, using light microscopy and toluidine blue as the staining agent. The results were analysed using SPSS version 10.0 computer software.

Result: The population of adenoid mast cells in children with OME was significantly greater than that in children without OME (p = 0.000).

Conclusion: The increased number of adenoid mast cells in patients with OME suggests that inflammation may play a role in this condition.

Objective: To compare the potential risk of blood contamination of the surgeon's conjunctiva during tonsillectomy using disposable bipolar diathermy and reusable monopolar diathermy.

Design: A prospective, single-blind, randomized, controlled trial.

Methods: Elective tonsillectomy was performed using either disposable bipolar diathermy or reusable monopolar diathermy. The operating surgeon wore a ViewsafeTM protective eyeshield which was later examined under an operating microscope by a blinded observer and the number of blood spots counted.

Results: One hundred and sixty-eight patients were enrolled. The relative risk of conjunctival contamination of the surgeon using disposable bipolar diathermy was 2.8 times that with reusable monopolar diathermy (chi-squared test, p < 0.0005). A previous history of peritonsillar abscess and additional adenoidectomy were associated with increased blood splatter.

Conclusion: The use of disposable bipolar diathermy for haemostasis during tonsillectomy poses a greater risk of conjunctival contamination for the surgeon than using reusable monopolar diathermy.

Introduction: Radical mastoidectomy and tympanomastoid obliteration with fat tissue, also called the Rambo operation, is proposed to those patients suffering chronic middle-ear disease, with or without cholesteatoma, who have no useful hearing in an ear which cannot be kept dry despite all conservative treatment.

Methods: We analysed retrospectively a series of 46 patients operated upon in our department. Information recorded included the surgical indications, surgical observations, post-operative care and complications. All patients were invited to comment on their long term anatomical and functional results and to express their degree of satisfaction with the procedure.

Results: Recurrent infectious episodes were observed in seven cases. Residual cholesteatoma were observed in three cases. After treatment, these patients did not present with further complications. One case presented with multiple episodes of infection with recurrences of cholesteatoma and finally had the obliterated cavity transformed into an open cavity again. For most of the patients, in the long term (i.e. one to 23 years post-operatively (mean eight years)), the operation resulted in a dry ear, ending the need for frequent consultations to clean and disinfect diseased ears or open cavities.

Conclusion: Obliteration of the tympanomastoid cavity, as proposed by Tom Rambo, shortens considerably the post-operative care period, in comparison with canal wall down mastoidectomy, and is therefore indicated if no serviceable hearing can be expected. In the long term, the rate of complications is low and patients are satisfied.

Objectives: Primary head and neck cancer and deep neck infection are not uncommon, but deep neck infection as the initial presentation of primary head and neck cancer is rare and these patients risk potential misdiagnosis.

Materials and methods: The records of 301 patients with deep neck infection and 3337 patients with primary head and neck cancers from 1990 to 2002 were retrospectively reviewed. Patients with primary head and neck cancers who had deep neck infection as their initial presentation were enrolled.

Results: Seven patients were identified (six men and one woman). The median age was 64 years. All patients presented with painful, erythematous neck swelling and all image studies showed abscess formation. Four abscesses received needle aspiration and three received surgical drainage, which yielded malignant cells in four specimens. The primary origins of malignancies were the nasopharynx (two patients), oropharynx (two patients), hypopharynx (one patient), parotid gland (one patient) and maxillary sinus (one patient). All patients had stage IV disease. Only three patients could receive curative therapy and only one patient was disease-free after three years.

Conclusion: We suggest that detailed history-taking, complete examination of the ENT field and pathological study of the infected tissue must be performed for patients with deep neck infection to enable early detection and prompt treatment of any underlying malignancy.

Introduction: Fifty per cent of brain abscesses in adults and 25 per cent of those in children are otogenic in origin. The current neurosurgical options are to drain the abscess repeatedly through burr holes or to excise it completely with the capsule. We successfully managed 10 cases of brain abscess by draining through the transmastoid route. The technique and its advantages are discussed.

Material and methods: The patients underwent surgery at two different institutions. Computed tomography scanning and magnetic resonance imaging were performed, along with diffusion-weighted imaging and in vivo proton magnetic resonance spectroscopy. The abscesses were drained via a transmastoid route.

Results: In eight cases, ear disease and brain abscess were treated in a single-stage procedure. In the remaining two cases, residual brain abscess was excised subsequently by our neurosurgical colleagues.

Conclusions: Transmastoid drainage of pus can successfully treat mastoid disease and brain abscess in a single surgical intervention. Residual abscess can be subsequently excised, with relatively reduced morbidity. Repeated needling is also avoided with this approach. Diffusion-weighted imaging and proton magnetic resonance spectroscopy are helpful.

A gastrostomy feeding tube has become the most acceptable method for long-term feeding support in patients with head and neck cancer. The aim of this study was to compare the complications of percutaneous endoscopically inserted gastrostomy (PEG) tubes, radiologically inserted gastrostomy (RIG) tubes and surgically inserted gastrostomy (open/laparoscopic) (SUR) tubes in head and neck cancer patients and also to compare the mortality rates of these patients.

Seventy-eight head and neck cancer patients underwent gastrostomy tube insertion (40 PEG, 28 RIG and 10 SUR) during the period February 2002 to February 2005. There were no significant demographic differences between the three groups. Thirty-six patients (46 per cent) developed complications, 32 minor and four major. All three groups were similar in their rate of minor complications, with the dislodgement and blockage rate being lowest in the PEG group (p > 0.05). The mortality rate was 4 per cent within 30 days of gastrostomy tube insertion. There were no deaths in the PEG group, two deaths in the RIG group and one in the SUR group. The PEG tube was considered superior to the RIG and SUR gastrostomy tubes, had fewer complications and was safer. Thus, PEG tube insertion is our first choice for head and neck cancer patients.

Potentially serious complications have been documented in patients undergoing upper airway surgery for obstructive sleep apnoea (OSA). Consensus is lacking regarding peri- and post-operative monitoring and identification of those patients likely to suffer post-operative complications.

This retrospective review of 118 patients treated and 152 surgical procedures undertaken, from January 1998 to December 2003, addresses this issue. The overall peri- and post-operative complication rate was 13.8 per cent, with one patient experiencing upper airway compromise, five patients experiencing post-operative oxygen desaturation within 150 minutes of extubation, six patients experiencing persistent hypertension and four patients suffering secondary haemorrhage. All patients were treated accordingly and recovered well, with no mortality. From these results, it is concluded that patients with severe OSA (apnoea–hypopnoea index > 60 and lowest oxygen saturation <80 per cent) are at higher risk of post-operative oxygen desaturation. Post-operative hypertension is more likely in patients with a prior history of hypertension. Routine post-operative admission to an intensive care unit for all OSA patients is unnecessary (including patients with severe OSA). However, all patients with OSA should be closely monitored in the post-anaesthesia care area for at least three hours after surgery; based on the outcome of this period and the clinical judgment of the clinician, the patient can then be observed overnight in either the high dependency unit or on a general ward. Patients with mild OSA may be admitted to the 23-hour ambulatory unit post-operatively. Use of continuous positive airway pressure in the immediate post-operative period can reduce the incidence of post-operative respiratory compromise and complications and is strongly recommended.

Background: The aim of this study was to evaluate the effect of nasal septal deviation (NSD) on ethmoid cell volume and to determine whether there was any correlation between NSD grade and ethmoid cell volume.

Methods: Forty computerized tomography (CT) scans from patients with rhinosinusitis symptoms with NSD were evaluated. Septal deviations were classified into three groups according to the degree of deviation on CT. Ethmoid cell volumes were measured and the relationship between NSD and ethmoid cell volume was investigated.

Results: There was a moderate but significant negative correlation between the septal deviation angle and the percentage of the ethmoid cell volumes (p = 0.001, r = −0.5152, r2 = 0.2654). Total ethmoid cell volume on the ipsilateral side compared with the contralateral side was found to decrease as the degree of NSD increased.

Conclusions: Nasal septal deviation affects the total ethmoid cell volume of the nasal cavity. The results of our study underline the role of ethmoid cell volume in the compensation mechanism equalizing the nasal cavity airflow changes due to NSD.

Nitinol stents have been used in the treatment of benign tracheal stenosis. A retrospective review of five patients treated at Stobhill Hospital over the last six and a half years is presented. Age at presentation ranged from 17 to 76 years. The minimum follow-up period was 23 months and the maximum was 78 months. All our patients were successfully decannulated, with none requiring recannulation. Four patients developed granulation tissue related to the stent at intervals ranging from three weeks to 41 months post stenting. Topical mitomycin C application has been useful after resection of granulations using the carbon dioxide (CO2) laser. Stent migration occurred in one patient three weeks after insertion. Nitinol stents are easy to insert and effective in the treatment of tracheal stenosis, but can have associated morbidity. Their use should be considered carefully, as insertion should be regarded as permanent. Publications reporting experience and outcome with the use of Nitinol stents in the trachea are reviewed.

Objective: To determine if patients who have had multiple previous nasal fractures and who undergo manipulation of fractured nasal bones under general anaesthetic (MUA) are as likely to be satisfied with their post-operative nasal cosmesis as patients who have only sustained a single injury.

Design: Telephone survey.

Setting: District general hospital.

Participants: Adult patients who had undergone MUA over the preceding three years.

Main outcome measures: Patient satisfaction with nasal cosmesis and nasal airway and willingness to consider corrective surgery.

Results: One hundred and two patients were contacted. Overall patient satisfaction with cosmesis and nasal airway was 82 and 77 per cent, respectively, with 15 per cent willing to consider a procedure to improve their nasal cosmesis and 12 per cent willing to consider a procedure to improve nasal airway. Twenty-three (22.5 per cent) gave a history of one or more nasal bone fractures, either treated or untreated, prior to the most recently treated injury. Patient satisfaction with cosmesis in this group was 65 per cent, compared with 87 per cent satisfaction in the single injury group (p = 0.03). No statistically significant differences were demonstrated when comparing these groups for: satisfaction with nasal airway (70 vs 80 per cent, p = 0.46); willingness to consider a procedure to improve cosmesis (26 vs 11 per cent, p = 0.16); and willingness to consider a procedure to improve nasal airway (17 vs 10 per cent, p = 0.46).

Conclusions: A history of multiple previous nasal fractures does appear to alter patient satisfaction with the cosmetic outcome of nasal manipulation. These patients should be informed that they have a decreased chance of attaining a cosmetically acceptable result.

With the increasing use of the endosheath in clinical practice, we set out to investigate the quality of the nasendoscope image produced with and without an endosheath. It has been suggested by some users that the endosheath degrades the image. We used a spectrophotometer to assess the optical transmission of the endosheath and found no selective chromatic absorption. However, on requesting nine experienced users to document whether they could differentiate between the sheathed and unsheathed endoscope, a significantly correct answering pattern was obtained in repeated blinded experiments. This suggests that individuals can distinguish between the sheathed and unsheathed nasendoscope view and that the image is indeed altered when an endosheath is employed.

A styloid process (SP) cutter was developed and put into clinical use. The design of components of the ‘styloidectome’ was based on the principles of mechanics. The measurements of the individual parts were determined on the basis of morphological data of the oropharynx from 40 subjects undergoing tonsillectomy under general anaesthesia. Experiments showed that the instrument could be used to transect the SP and excise the amputated bones from the deep tissue space. We used the instrument for the resection of elongated SPs, via an oral approach, in seven in-patients (involving 10 SPs) under general anaesthesia and in two out-patients (involving three SPs) under local anaesthesia. The length of the resected SP ranged from 0.8 to 2.5 cm and the stump of the SP was smooth. The removal lasted only seconds and blood loss was minimal, without any complications. The styloidectome was reliable, easy to use and could be used for the resection of an elongated SP under general or local anaesthesia.

Laser-assisted uvulopalatoplasty (LAUP) is an established treatment for snoring. Our institution has been using a modification of the Kamami technique since 1995. Between January 1995 and December 2001, 469 patients underwent LAUP for snoring. A telephone survey of these patients and their partners was conducted retrospectively. One hundred and sixty-eight patients and their partners were interviewed and the findings analysed.

Of the 168 patients, 122 had LAUP alone, 42 had LAUP and tonsillectomy and four had LAUP and septoplasty. The median follow-up time was 59 months (range 19 to 98 months).

Seventy-four per cent reported improvement at six weeks, 69 per cent reported improvement at nine months and 55 per cent reported improvement at the time of interview. To assess the degree of improvement, patients and their partners were asked to grade any improvement in percentage terms. The mean subjective improvement scores were 57 per cent at six weeks (95 per cent confidence interval (CI) 50–64 per cent), 45 per cent at nine months (95 per cent CI 38–59 per cent) and 30 per cent at the time of interview (95 per cent CI 23–35 per cent). Patients who reported weight gain since surgery did not have a poorer outcome than those who reported no weight change or weight loss. Neither did weight loss predict a better outcome. The procedure was generally well tolerated, with only 30 patients (18 per cent) reporting complications (mainly minor).

The benefits of LAUP wane with time and the results are best in the first 12 months following surgery. Our study suggests that 55 per cent of patients selected after sleep studies and sleep nasendoscopy will enjoy long-term benefit.

Objective: To document the outcome of patients deemed at initial diagnosis to be appropriate for palliative care.

Materials and methods: Over a five-year period, all patients with head and neck mucosal squamous cell carcinoma (HNMSCC) were referred to one consultant surgeon, and data were collated retrospectively.

Results: Of 286 patients with HNMSCC, 60 (21 per cent) were deemed appropriate for palliative care at initial diagnosis. Their median survival was 154 days, with hypopharyngeal and oropharyngeal tumours forming a disproportional percentage of the initial diagnoses (p < 0.001). After initial assessment, 66 per cent of patients were discharged to their home, 17 per cent to hospice care and 17 per cent were transferred to other institutions. Including deaths during the initial admission, 29 per cent of patients did not return home after diagnosis. Palliative treatment included operative interventions in 35 per cent and radiotherapy in 43 per cent. Time spent in further hospital care averaged 47 days, and 47 per cent of patients eventually died in hospital.

Conclusion: One in five patients presenting with HNMSCC were deemed appropriate for palliative care at initial presentation and survived less than six months after diagnosis. More than one-third required surgical intervention, and 29 per cent never returned home.

Objectives: To explore the interpretation of words commonly used to describe lumps. Specific words were explored to assess their understandability and implication of threat to the patient.

Methods: A cross-sectional, questionnaire-based study was undertaken. Age, gender, level of education, employment and socio-economic group were determined. The questionnaire explored the following words: malignant, tumour, carcinoma, lymphoma, sarcoma, lipoma, lymph node, nodule, ganglion, benign, cyst and gland. Participants comprised 204 consecutive adult patients attending the ENT out-patient clinic at a Bristol teaching hospital.

Results: Patients found ‘malignant’ and ‘tumour’ the most threatening words and were most unsure of the meaning of ‘sarcoma’ and ‘lipoma’. Nineteen per cent (n = 37) thought a ‘benign’ lump was a cancer. Results did not significantly differ between demographic groups.

Conclusions: A significant misunderstanding of some words commonly used to describe lumps was found. This study provides important guidance on which terms to use and which to avoid in consultations with patients.
