This study aimed to evaluate the association of chronic rhinosinusitis with sudden sensorineural hearing loss using a population-based database.

Sampled subject data were obtained from the Taiwan Longitudinal Health Insurance Database 2000. A total of 3325 patients with sudden sensorineural hearing loss were identified and 9975 controls were randomly selected. A conditional logistic regression was used to calculate the odds ratio for having been previously diagnosed with chronic rhinosinusitis, for cases and controls.

The adjusted odds ratio of having prior chronic rhinosinusitis among cases compared to controls was 1.36 (95 per cent confidence interval = 1.16–1.60). The significant relationship between sudden sensorineural hearing loss and chronic rhinosinusitis was most pronounced among those patients aged 44 years or less (compared to controls) (odds ratio = 2.18; 95 per cent confidence interval = 1.63–2.92). However, the significant relationship between sudden sensorineural hearing loss and prior chronic rhinosinusitis was not sustained for patients older than 60 years compared to controls.

This study aimed to compare the efficacies of intratympanic dexamethasone and methylprednisolone in preventing in cisplatin-induced ototoxicity in rats.

Experimental groups of rats (n = 8 each) received intratympanic isotonic saline, intraperitoneal cisplatin and intratympanic isotonic saline, intraperitoneal cisplatin and intratympanic dexamethasone, or intraperitoneal cisplatin and intratympanic methylprednisolone. Distortion product otoacoustic emission thresholds were compared on days 0 and 10 in all rats, and correlations between drug effects and changes in cochlear histology were evaluated.

Distortion product otoacoustic emission thresholds were comparable in groups III and IV (p > 0.05). Significant protection against cisplatin-induced ototoxicity was seen in groups III and IV compared with group II (p < 0.05). Dexamethasone and, to a lesser extent, methylprednisolone protected against cellular apoptosis in cisplatin-induced ototoxicity.

Dexamethasone (and possibly methylprednisolone) may be clinically useful as an intratympanic chemopreventive agent to treat cisplatin ototoxicity. Future clinical studies should investigate the use of dexamethasone for this purpose in adult patients.

To evaluate our results in treating Zenker's diverticulum via the transcervical approach, and to compare our experiences with a recent systematic review of both open and endoscopic approaches to the pharyngeal pouch.

An audit yielded 41 consecutive cases of Zenker's diverticulum treated between 2003 and 2013.

All 41 patients underwent transcervical cricopharyngeal myotomy; 29 sacs also required ‘inversion’. The median and mean length of hospital stay was 1 night and 2.5 nights respectively. The recurrence rate was 2.4 per cent and the complication rate was 9.8 per cent.

When compared to reported endoscopic techniques, transcervical cricopharyngeal myotomy (with or without inversion) in our unit resulted in: shorter hospital stay, a comparable complication rate and fewer recurrences.

To investigate the anti-inflammatory, anti-oxidative and tissue protective effects, as well as the potential therapeutic role, of alpha-lipoic acid in experimentally induced acute otitis media.

Twenty-five guinea pigs were assigned to one of five groups: a control (non-otitis) group, and otitis-induced groups treated with saline, penicillin G, alpha-lipoic acid, or alpha-lipoic acid plus penicillin G. Tissue samples were histologically analysed, and oxidative parameters in tissue samples were measured and compared between groups.

The epithelial integrity was better preserved, and histological signs of inflammation and secretory metaplasia were decreased, in all groups compared to the saline treated otitis group. In the alpha-lipoic acid plus penicillin G treated otitis group, epithelial integrity was well preserved and histological findings of inflammation were significantly decreased compared to the saline, penicillin G and alpha-lipoic acid treated otitis groups. The most favourable oxidative parameters were observed in the control group, followed by the alpha-lipoic acid plus penicillin G treated otitis group.

Alpha-lipoic acid, with its antioxidant, anti-inflammatory and tissue protective properties, may decrease the clinical sequelae and morbidity associated with acute otitis media.

To determine the age of onset of Ménière's disease in patients who visited a specialised dizziness clinic, and to verify whether the trend of a delayed onset age of Ménière's disease as reported for the Japanese population also occurs in the Netherlands.

A retrospective data analysis was performed of patients diagnosed with ‘definite’ Ménière's disease who visited our clinic between January 2000 and December 2013.

Mean onset age of Ménière's disease among the 296 patients was 53.0 ± 14.1 years; 209 patients (71 per cent) were diagnosed between the fifth and seventh decades of life. No trend towards a later onset of Ménière's disease was found (regression beta co-efficient for year of presentation was 0.03; 95 per cent confidence interval = −0.34–0.61; p = 0.58).

Ménière's disease has a peak incidence between 40 and 69 years of age. No shift towards a later onset age of Ménière's disease was found.

Subtotal petrosectomy combined with cochlear implantation is a procedure required in specific situations.

A retrospective review of all cases of subtotal petrosectomy in cochlear implant surgery over a five-year period was performed. The indications, complications and outcomes for this procedure are outlined.

Sixteen patients underwent cochlear implantation in combination with subtotal petrosectomy and blind sac closure of the external auditory meatus from 2008 to 2013. Seventy-five per cent of these were completed as a two-stage procedure and 25 per cent as a single-stage procedure. The most common indications for the procedure were chronic otitis media, previous radical cavity, and for surgical access in challenging anatomy or in drill-out procedures. Mastoids were obliterated with fat or musculoperiosteal flaps. The complication rate relating to blind sac closure was 6 per cent. Cochlear implants were successfully placed in all cases and there was no incidence of device failure.

For patients with chronic suppurative otitis media or existing mastoid cavities, subtotal petrosectomy with blind sac closure of the external auditory canal, closure of the eustachian tube, and cavity obliteration is an effective technique to facilitate safe cochlear implantation.

This study aimed to compare the diagnostic effectiveness of narrow band imaging and autofluorescence imaging for malignant laryngopharyngeal tumours.

Between May 2010 and October 2010, 50 consecutive patients with suspected laryngopharyngeal tumour underwent endoscopic laryngopharynx examination. The morphological characteristics of laryngopharyngeal lesions were analysed using high performance endoscopic systems equipped with narrow band imaging and autofluorescence imaging modes. The diagnostic effectiveness of white light image, narrow band imaging and autofluorescence imaging endoscopy for benign and malignant laryngopharyngeal lesions was evaluated.

Under narrow band imaging endoscopy, the superficial microvessels of squamous cell carcinomas appeared as dark brown spots or twisted cords. Under autofluorescence imaging endoscopy, malignant lesions appeared as bright purple. The sensitivity of malignant lesion diagnosis was not significantly different between narrow band imaging and autofluorescence imaging modes, but was better than for white light image endoscopy (χ2 = 12.676, p = 0.002). The diagnostic specificity was significantly better in narrow band imaging mode than in both autofluorescence imaging and white light imaging mode (χ2 = 8.333, p = 0.016).

Narrow band imaging endoscopy is the best option for the diagnosis and differential diagnosis of laryngopharyngeal tumours.

Vestibular schwannomas are a rare cause of asymmetrical hearing loss, and routine screening with magnetic resonance imaging can be costly. This paper reports results on vestibular schwannoma screening at our institution and compares the cost of screening to a utility of hearing benefit.

All screening examinations with magnetic resonance imaging performed for asymmetrical hearing loss between 2006 and 2011 were retrospectively reviewed. The cost per new vestibular schwannoma diagnosis was calculated. The cost per patient for those who benefitted from intervention was estimated based on rates of hearing preservation reported in the literature.

Forty-five (4.3 per cent) of 1050 screening examinations with magnetic resonance imaging performed for asymmetrical hearing loss were positive for vestibular schwannoma, and the cost per new diagnosis was $11 436. The estimated screening cost per patient for those who benefitted from surgery or radiation was $147 030, while US federal compensation for unilateral hearing loss was $44 888.

Although we achieved a lower screening cost per new diagnosis than reported in the current literature, there remains disparity between the screening cost per benefitted patient and the ‘benefit’ of hearing.

To investigate whether cochlear involvement is an extraintestinal manifestation in patients with ulcerative colitis.

Forty-four ulcerative colitis patients and 44 age-matched healthy subjects were included in the study. Pure tone and speech audiometry, and distortion product otoacoustic emission tests were performed on all participants. The audiometric test results were compared between groups and their relationship with disease activity was investigated.

Pure tone threshold averages were significantly higher in ulcerative colitis patients compared to controls (p < 0.05). Speech discrimination scores were significantly lower in ulcerative colitis patients compared to controls (p < 0.05). Distortion product otoacoustic emission amplitude values were significantly lower for all of the tested frequencies (except for 6000 Hz in the right ear) in ulcerative colitis patients compared to controls (p < 0.05). No relationship was detected between audiometric test results and disease activity (p > 0.05).

Even though hearing thresholds may be within normal limits, decreased distortion product otoacoustic emission amplitude values indicate a cochlear involvement in ulcerative colitis patients.

To compare the clinical effectiveness and adverse events for 3 per cent boric acid in 70 per cent alcohol versus 1 per cent clotrimazole solution in the treatment of otomycosis.

A total of 120 otomycosis patients were randomly assigned to receive either 1 per cent clotrimazole solution (intervention group) or 3 per cent boric acid in 70 per cent alcohol (control group) at the Khon Kaen Hospital ENT out-patient department. Treatment effectiveness was determined based on the otomicroscopic absence of fungus one week after therapy, following a single application of treatment.

After 1 week of treatment, there were data for 109 participants, 54 in the clotrimazole group and 55 in the boric acid group. The absolute difference in cure rates between 1 per cent clotrimazole solution and 3 per cent boric acid in 70 per cent alcohol was 17.9 per cent (95 per cent confidence interval, 2.3 to 33.5; p = 0.028) and the number needed to treat was 6 (95 per cent confidence interval, 3.0 to 43.4). Adverse events for the two agents were comparable.

One per cent clotrimazole solution is more effective than 3 per cent boric acid in 70 per cent alcohol for otomycosis treatment.

GJB2 gene mutations are highly prevalent in pre-lingual hearing loss patients from China. Pre-lingual deafness is a sensorineural disorder that can only be treated with cochlear implantation.

The prevalence of GJB2 gene mutations was examined in 330 randomly selected patients treated with cochlear implantation.

Overall, 276 patients (83.64 per cent) carried variations in the GJB2 gene. Seventeen different genotypes were identified, including 10 confirmed pathogenic mutations (c.235delC, c.299delAT, c.176del16, p.E47X, p.T123N, p.V167M, p.C218Y, p.T86R, p.V63L and p.R184Q), 3 polymorphisms (p.V27I, p.E114 G and p.I203 T) and 2 unidentified mutations (p.V37I and c.571 T > C).

A total of 103 patients (31.2 per cent) carried 2 confirmed pathogenic mutations. The frequency of c.235delC was higher than that reported previously in the Jiangsu province. The two novel mutations identified, 69C > G and 501G > A, are likely to be polymorphisms.

There has been increasing emphasis on performing ‘same-day’ or ‘out-patient’ thyroidectomy to reduce associated costs. However, acceptance has been limited by the risk of potentially life-threatening post-operative bleeding. This study aimed to review current rates of post-operative bleeding in a metropolitan teaching hospital and identify risk factors.

Medical records of patients undergoing thyroidectomy between January 2007 and March 2012 were reviewed retrospectively. Pre-operative, operative and pathological data, and post-operative complication data, were examined.

The study comprised 205 thyroidectomy cases. Mean age was 51.6 years (standard deviation = 14.74), with 80 per cent females. Unilateral thyroidectomy was performed in 81 cases (39.5 per cent) and total thyroidectomy was performed in 74 cases (36.1 per cent; 5.3 per cent with concomitant lymph node dissection). Nine patients (4.4 per cent) suffered post-operative bleeding, of which six required re-operation. Analysis showed that post-operative systolic blood pressure of 180 mmHg or greater was associated with post-operative bleeding (p = 0.003, chi-square test).

Rates of significant post-operative bleeding are consistent with recent literature. Post-operative hypertension, diabetes and high post-operative drain output were identified as independent risk factors on multivariate analysis; when identified, these may be caveats to same-day discharge of thyroidectomy patients.

To compare the auditory outcomes of Carina middle-ear implants with those of conventional hearing aids in patients with moderate-to-severe mixed hearing loss.

The study comprised nine patients (six males, three females) who underwent middle-ear implantation with Carina fully implantable active middle-ear implants to treat bilateral moderate-to-severe mixed hearing loss. The patients initially used conventional hearing aids and subsequently received the Carina implants. The hearing thresholds with implants and hearing aids were compared.

There were no significant differences between: the pre-operative and post-operative air and bone conduction thresholds (p > 0.05), the thresholds with hearing aids and Carina implants (p > 0.05), or the pre-operative (mean, 72.8 ± 19 per cent) and post-operative (mean, 69.9 ± 24 per cent) speech discrimination scores (p > 0.05). One of the patients suffered total sensorineural hearing loss three months following implantation despite an initial 38 dB functional gain. All except one patient showed clinical improvements after implantation according to quality of life questionnaire (Glasgow Benefit Inventory) scores.

Acceptance of Carina implants is better than with conventional hearing aids in patients with mixed hearing loss, although both yield similar hearing amplification. Cosmetic reasons appear to be critical for patient acceptance.

Platelet-rich plasma is a novel material that is being used more frequently in many surgical specialties.

A literature review on the current and potential uses of platelet-rich plasma in otolaryngology was performed.

There is limited evidence on the use of platelet-rich plasma in otolaryngology compared with other specialties: only 11 studies on various subspecialties (otology, rhinology and laryngology) were included in the final review.

Based on the limited number of studies, we cannot draw safe conclusions about the value of platelet-rich plasma in otolaryngology. Nevertheless, the available literature suggests that platelet-rich plasma holds promise for future research and may have a number of clinical applications.

To measure the output sound pressure levels of personal music systems and evaluate their effect on hearing.

Output sound pressure levels at preferred volume settings and listening environment were measured using a manikin. Effects of personal music system use on hearing were evaluated using pure tone audiometry (in conventional and extended high frequency ranges), transient evoked otoacoustic emissions, syllable identification in noise, intensity discrimination, frequency discrimination and temporal modulation transfer function.

Results showed, alarmingly, that large proportions of young adults are using personal music systems at levels higher than the safety limits set by regulatory bodies. Individuals who listened to personal music systems at levels higher than 80 dB LAeq exhibited poorer extended high frequency thresholds, reduced transient evoked otoacoustic emission amplitudes, poorer frequency discrimination, reduced modulation detection thresholds at 32 Hz modulation frequency, and reduced syllable identification in noise at −5 dB signal-to-noise ratio. Listening levels were significantly correlated with extended high frequency thresholds and transient evoked otoacoustic emission amplitudes.

These results suggest that listening to music through personal music systems at higher volume levels may be hazardous to hearing.

This study aimed to assess the experiences and outcomes of patients who underwent surgical repair of a perilymph fistula in Norfolk, UK.

The study involved a retrospective questionnaire-based patient survey and case note review of patients who had undergone tympanotomy and perilymph fistula repair between 1998 and 2012 in two district general hospitals.

Fourteen patients underwent 20 procedures, of whom 7 completed the pre- and post-operative Vertigo Symptom Scale. In five patients, there was no obvious precipitating cause. Perilymph fistula was precipitated by noise in one patient, by a pressure-increasing event in six patients and by trauma in two patients. The Vertigo Symptom Scale scores showed a statistically significant improvement following surgical repair, from a median of 67 (out of 175) pre-operatively to 19 post-operatively.

In selected patients with vertigo, perilymph fistula should be considered; surgical repair can significantly improve symptoms.

Cholesteatoma is keratinising epithelium within the middle-ear cleft or mastoid. This disease destroys the peripheral organs of balance and hearing, with possible intracranial sequelae. The management of cholesteatoma is surgical and the primary aim is to remove the disease and prevent recurrence. Secondary aims are to obtain a non-discharging, hearing ear. Cholesteatoma surgery falls into two broad categories: open cavity surgery and combined approach surgery. A third surgical category is reconstruction of an open mastoid cavity after open surgery. This study performed a pooled analysis of the worldwide literature to compare the rates of cholesteatoma not being cured (i.e. recidivism), ear discharge and hearing change among open cavity, combined approach and reconstruction mastoid surgery for primary cholesteatoma.

A literature search for all types of cholesteatoma surgery in the PubMed, Google Scholar and Medline databases and in published conference proceedings was undertaken.

There was no level 1 evidence for the best method of primary cholesteatoma surgery. The highest evidence level found (level 2; 5366 patients) shows no difference in hearing change or discharge rate between open and combined approach surgery; however, these methods fail to cure the cholesteatomas in 16.0 per cent and 29.4 per cent of cases, respectively. In a total of 640 patients, reconstruction and/or repair mastoid surgery using a variety of non-comparable techniques had a failure rate of between 5.3 per cent and 20 per cent.

The available evidence suggests that reconstruction of the posterior canal wall and/or obliteration of the mastoid may be the best surgical treatment alternative. This technique appears to provide the lowest recidivism rate combined with a low post-operative ear discharge rate.

Necrotising otitis externa is associated with high morbidity and mortality rates. This study investigated whether temporomandibular joint involvement had any prognostic effect on the course of necrotising otitis externa in patients who had undergone hyperbaric oxygen therapy after failed medical and sometimes surgical therapy.

A retrospective case series was conducted of patients in whom antibiotic treatment and surgery had failed, who had been hospitalised for further treatment and hyperbaric oxygen therapy.

Twenty-three patients with necrotising otitis externa were identified. The temporomandibular joint was involved in four patients (17 per cent); these patients showed a constant gradual improvement in C-reactive protein and were eventually discharged free of disease, except one patient who was lost to follow up. Four patients (16 per cent) without temporomandibular joint involvement died within 90 days of discharge, while all patients with temporomandibular joint involvement were alive. Three patients (13 per cent) without temporomandibular joint involvement needed recurrent hospitalisation including further hyperbaric oxygen therapy; no patients with temporomandibular joint involvement required such treatment.

Patients with temporomandibular joint involvement had lower rates of recurrent disease and no mortality. Therefore, we suggest considering temporomandibular joint involvement as a positive prognostic factor in necrotising otitis externa management.
