RESUMO
INTRODUCTION: Necrotising otitis externa (NOE) is a rare infection causing skull base osteomyelitis. The evidence regarding NOE consists mostly of case series. Hence, there is a limited evidence base to guide decision-making. This survey aims to report the experience of 221 otolaryngologists in this condition. MATERIALS AND METHODS: Internet survey administered to the membership of the British Association of Otorhinolaryngology - Head and Neck Surgery (ENT UK). RESULTS: Respondents' detailed replies on diagnosis, treatment and follow up are presented. One third of respondents reported increasing incidence of NOE. Over 80% diagnosed NOE based on pre-existing risk factors, severe pain, non-resolution of infection and CT scan. Most respondents managed NOE with intravenous antibiotics (90%) and blood sugar control (82%). There was less agreement in certain aspects of management including the role of surgery and the nature and duration of follow up. CONCLUSIONS: Our survey provides a picture of NOE management in the UK. While there is consensus in some aspects of NOE management, other aspects attract widely differing answers. This may reflect the lack of strong evidence in the literature. Future work should aim to address this.

OBJECTIVE: Assess the relative efficacy and results of the round window hyaluronic acid pledget depot method for intratympanic gentamicin delivery in Ménière's disease. STUDY DESIGN: Retrospective case review. SETTING: Tertiary referral hospital. PATIENTS: Prospective symptomatic and audiologic data were collected on 28 patients undergoing intratympanic gentamicin therapy for Ménière's disease refractory to medical treatment between 2003 and 2009. INTERVENTION: All patients had the round window membrane exposed via a tympanomeatal flap, and any adhesions were removed. Hyaluronic acid pledgets soaked in 40 mg/ml of gentamicin were then packed into the round window niche and posterior mesotympanum, and the tympanomeatal flap was replaced. MAIN OUTCOME MEASURES: Patients audiologic and vertigo symptom outcome scores were recorded at follow-up according to the AAO-HNS 1995 guidelines for reporting results in Ménière's disease. RESULTS: Complete or substantial improvement in vertigo (class A or B) was achieved in 88.5% (23/26) of patients. Hearing loss, defined as greater than 10 dB (PTA average at 0.5, 1, 2, and 4 kHz) was noted in 12 (50%) of 24 patients including 4 patients who had developed "dead ears" (16%). The average hearing loss for all patients excluding the 4 patients with dead ears was 10.7 dB. CONCLUSION: Round window hyaluronic acid pledget technique used as a sustained delivery vehicle for intratympanic gentamicin treatment for Ménière's disease produces similar rates of vertigo control compared with other techniques but a greater risk of hearing loss. We would recommend the intratympanicinjection titration technique as first line for most patients.

We present a case of a highly unusual stapes in the presence of a normal external ear. The stapes exhibits rudimentary anterior crus with abnormally shaped posterior crus that attached to the mid-portion of a fixed, rudimentary footplate. To our knowledge, this anomaly has not been previously documented. We review the embryological cause that may be contributing to the development of this congenitally abnormal stapes superstructure. This is to highlight the importance of the knowledge of the anatomy of the stapes and its variations especially to the otologists.
