The potential effect of the updated national criteria on adult cochlear implantation in England and Wales.

OBJECTIVES: Following an update of 'old' TA166 guidance (March 2019), the National Institute for Health and Care Excellence (NICE) predicted a 70% increase in cochlear implantation (CI). We investigated the effect of the 'new' TA566 criteria on adult CI at our regional centre. METHODS: Adult CI assessments between 1st January 2015 and 31st December 2018 (before new criteria) and between 7th March 2019 and 31st August 2019 (after new criteria) were retrospectively examined. Calculated eligibility and uptake rates predicted change in annual implantation under the new guidance. RESULTS: 552 patients were identified in the first study period, with a median of 148 assessments per year. Of 533 with complete assessments, 58% were eligible, of whom 74% were implanted. Retrospective application of the new criteria was possible for 277 patients; eligibility and uptake were 67% and 80%, respectively. In the second study period (n = 60), new criteria eligibility was 62% and uptake was 78%. Increased eligibility under the new criteria predicts an increase of between 13 and 23% in annual adult implantation. CONCLUSIONS: We demonstrate increased implant eligibility under the latest NICE guidance. Assuming consistent referral patterns, our predicted increase in adult implantation is considerably less than that predicted elsewhere.

Hold your horses: A comparison of human laryngomalacia with analogous equine airway pathology.

OBJECTIVES: Laryngomalacia is the most common cause of stridor in infants. Dynamic airway collapse is also a well-recognised entity in horses and an important cause of surgical veterinary intervention. We compare the aetiology, clinical features and management of human laryngomalacia with equine dynamic airway collapse. METHODS: A structured review of the PubMed, the Ovid Medline and the Cochrane Collaboration databases (Cochrane Central Register of Controlled Trials, Cochrane Database of Systemic Reviews). RESULTS: There are numerous equine conditions that cause dynamic airway collapse defined specifically by the anatomical structures involved. Axial Deviation of the Aryepiglottic Folds (ADAF) is the condition most clinically analogous to laryngomalacia in humans, and is likewise most prevalent in the immature equine airway. Both conditions are managed either conservatively, or if symptoms require it, with surgical intervention. The operative procedures performed for ADAF and laryngomalacia are technically comparable. CONCLUSION: Dynamic collapse of the equine larynx, especially ADAF, is clinically similar to human laryngomalacia, and both are treated in a similar fashion.

Does incidental mastoid opacification on computerized tomography necessitate referral to ENT?

OBJECTIVE: The prevalence of incidental temporal bone disease on magnetic resonance imaging has been widely reported in the medical literature. Despite this, there currently is little evidence regarding incidental otological disease on computerized tomography (CT). Thus, the study aimed to review the CT prevalence of asymptomatic adult ear disease and evaluate the appropriateness of ear, nose, and throat (ENT) referral following its discovery. STUDY DESIGN: Retrospective observational study of 468 CT scans. METHODS: All CT head scans performed between January 2015 and January 2016 containing the keyword mastoid in the radiological report initially were recruited for the study. Scans performed in the pediatric population following head trauma or for otological indications were excluded, leaving 468 eligible radiological images. The presence of prior otological disease or referral subsequently was established using electronic patient records. RESULTS: Mastoid and/or middle ear opacification was noted to be present in 62 patients (13%). Of these patients, 10 subsequently were found to have prior otological intervention or review. Following exclusion of these patients, the rate of incidental temporal bone disease was recorded as 11%. CONCLUSION: Data from this study suggests that incidental findings in an asymptomatic individual do not necessitate referral or further intervention. Furthermore, it is the author's recommendation that radiological findings be closely correlated with clinical examination to reduce false diagnosis and inappropriate referral to ENT.

Non-recurrent laryngeal nerve with a coexisting contralateral nerve demonstrating extralaryngeal branching.

Non-recurrence and extralaryngeal branching are 2 of the more frequently encountered anomalies of the recurrent laryngeal nerve. If not anticipated intraoperatively, these abnormalities can put the nerve at risk, with subsequent vocal cord palsy. It is therefore important to report on and understand these abnormalities. We present a unique case of a non-recurrent laryngeal nerve with a coexisting contralateral nerve demonstrating extralaryngeal branching. This case allows us to demonstrate the importance of arteria lusoria in head and neck surgery, and to conclude that non-recurrence and extralaryngeal branching can occur separately within individual nerves in the same patient. The case also highlights the importance of a systematic intraoperative approach to the identification of every recurrent laryngeal nerve, especially in bilateral procedures having already exposed an anomalous nerve on one side.
