The proper positioning of the Nerve Integrity Monitoring® endotracheal tube during recurrent laryngeal nerve monitoring is of paramount importance. This article describes our experience with the GlideScope® and explains how it can facilitate the accurate placement of the Nerve Integrity Monitoring endotracheal tube.

Endotracheal intubation with the Nerve Integrity Monitoring endotracheal tube was performed in 250 patients undergoing thyroidectomies using the GlideScope video laryngoscope. The correct positioning of the tube was determined according to impedance values of less than 5 kohm and an impedance imbalance of less than 1 kohm.

Successful intubation was achieved in all cases. The GlideScope aided the correct placement of the Nerve Integrity Monitoring endotracheal tube in the majority of the cases.

The GlideScope provides an excellent means to ensure the correct positioning of the Nerve Integrity Monitoring tube. It allows both the surgeon and the anaesthesiologist to participate in the intubation process and confirm correct placement of the tube, whilst also allowing gentle intubation with improved visibility.

To study the effect of a new technique for closed reduction of dislocated arytenoids.

The study included 21 females (72.4 per cent) and eight males (27.6 per cent) with a diagnosis of arytenoid dislocation. There were 18 cases of left arytenoid dislocation and 11 of right arytenoid dislocation.Twenty-eight cases had anteromedial dislocation and one had posterolateral dislocation. All patients were treated with closed reduction using custom-made metal rods and an operating microscope, under general anaesthesia.

Post-operatively, 21 patients’ voices returned completely to normal (including full vocal fold mobility), five had an improved voice and three failed to show any improvement. There were no post-operative complications.

This new closed reduction technique is a safe procedure for patients with dislocated arytenoids. It is repeatable and the outcome is reliable and effective. Closed reduction can be a useful treatment for arytenoid dislocation.

To demonstrate that patients who have been intubated for prolonged periods of time will have an increased likelihood of developing bacterial biofilm on their endotracheal tubes.

We collected endotracheal tubes from patients at the time of extubation, and analysed representative sections with scanning electron microscopy for morphologic evidence of biofilms.

From September 2007 to September 2008, 32 endotracheal tubes were analysed with electron microscopy. Patients who had been intubated for 6 days or longer had a significantly higher percentage of endotracheal tubes that exhibited bacterial biofilms, compared with patients intubated for less than 6 days (88.9 versus 57.1 per cent, p = 0.0439).

Longer duration of intubation is associated with a higher incidence of bacterial biofilm. Further research is needed to link the presence of bacterial biofilms to acquired laryngotracheal damage.

The incidence of acquired laryngeal stenosis is increasing. This retrospective study aimed to assess the long term results of circumferential resection with end-to-end tracheal anastomosis for isolated post-intubation stenosis of the cervical trachea, and to review the relevant literature.

Twelve male and two female patients (aged 16–30 years, mean age 24 years) treated between February 2003 and December 2008 were included. Hospital and office records were reviewed and relevant surgical details recorded.

Indications for tracheal resection anastomosis were post-intubation stenosis (78.57 per cent) and trauma (21.42 per cent). One to five tracheal rings were resected (i.e. 1–2.5 cm of cervical trachea). Tracheal anastomosis was considered successful if the patient remained asymptomatic for 24 months of close follow up (involving regular flexible bronchoscopy and neck X-ray). The anastomotic success rate was 92.85 per cent.

Tracheal resection and end-to-end anastomosis is relatively safe and reliable for definitive treatment of benign tracheal stenosis in appropriate patients. Local application of mitomycin C prevents granulation and aids long term airway patency.
