Introduction: Vestibular schwannomas (VS) are a rare cause of asymmetrical hearing loss, and routine screening with magnetic resonance imaging (MRI) can be costly. At present, no consensus exists on what qualifies as “asymmetrical sensorineural hearing loss” (ASNHL) and when a patient should be referred for screening. Objectives: 1) Evaluation of published audiometric protocols on the basis of sensitivity and specificity when applied to local clinical cohort of patients with ASNHL; 2) determination of clinical risks of missing VS and potential wastes in screening “radiologically normal” cases; 3) assessment of the cost of MRI screening. Methods: Cross-sectional study with chart review in a 2-year (2015–2016) cohort of 1059 patients who underwent MRI screening and audiometry indicating sensorineural hearing loss. Fourteen previously published audiometric protocols were assessed for their sensitivity and specificity in guiding radiological diagnosis of VS, and cost analysis was performed. Results: 6/14 audiometric protocols had a sensitivity greater than 85%. Diagnostic specificity ranged from 22.91 to 82.76%, clinical risks from 0 to 50%, and potential wastes from 17.24 to 77.09%. Average annual cost of screening was £64,069. Application of proposed local screening protocol had a projected cost saving of 32.19%. Cost of screening patients that benefit from treatment was compared with a utility function that quantified expected benefit. Conclusions: Development of an easy-to-apply algorithm incorporating high-sensitivity audiometric protocols may result in significant cost saving, with minimal clinical risk of missing cases. There was disparity between screening costs and monetary “benefit” of hearing.

SUMMARYObstructive sleep apnoea is a common presentation in paediatric ear, nose and tongue (ENT) outpatients. The use of sleep studies is controversial however once a diagnosis has been made, frequently treatment is surgery. Should these patients be operated on as urgent cases? A 5-year-old boy was admitted under the paediatric team with difficultly breathing and desaturations to 77%. The patient had previously been seen by ENT as an outpatient with an 8-month history of obstructive sleep apnoea and was listed for an adenotonsillectomy with the standard waiting time. During this admission he had an emergency adenotonsillectomy. The patient improved immediately with no large desaturations in recovery and normal observations throughout his stay. It is never ideal to do a paediatric emergency operation and we have reviewed the evidence base to answer the question: Should these patients be treated urgently when seen in outpatients?BACKGROUND

Background Pharyngocutaneous fistula is a troublesome complication. Recently, synthetic materials such as fibrin sealant have been used as a secondary measure to treat fistula. This work assessed whether the primary use of fibrin sealant can reduce the rate of fistula. Method A retrospective review of 50 cases from 2 centres was completed. Tisseel was an adjunct to primary closure in all cases. Results In the first centre, 3 out of 34 cases developed pharyngocutaneous fistula (fistula rate of 9 per cent). All three were salvage cases. In the second centre, 0 out of 16 cases developed a fistula. Conclusion The incidence of pharyngocutaneous fistula post-radiation and post-chemoradiotherapy in laryngectomy cases has been quoted as 23 per cent and 34 per cent respectively. This study represents the first patient series on the use of fibrin sealant as an adjunct in primary closure following laryngectomy. The results are promising, encouraging the use of Tisseel as an adjunct to meticulous closure.
