IVORY Guidelines (Instructional Videos in Otorhinolaryngology by YO-IFOS): A Consensus on Surgical Videos in Ear, Nose, and Throat.

OBJECTIVES/HYPOTHESIS: Otolaryngology instructional videos available online are often of poor quality. The objective of this article was to establish international consensus recommendations for the production of educational surgical videos in otolaryngology. STUDY DESIGN: DELPHI survey. METHODS: Twenty-seven international respondents participated in this study from 12 countries. Consensus was reached after three rounds of questionnaires following the Delphi methodology. The proposals having reached the 80% agreement threshold in the third round were retained. RESULTS: The main recommendations are as follows: 1) Ethics: patients must be anonymized and unrecognizable (apart from plastic surgery if necessary). A signed authorization must be obtained if the person is recognizable. 2) Technical aspects: videos should be edited and in high-definition (HD) quality if possible. Narration or subtitles and didactic illustrations are recommended. 3) Case presentation: name of pathology and procedure must be specified; the case should be presented with relevant workup. 4) Surgery: surgical procedures should be divided into several distinct stages and include tips and pitfalls. Pathology should be shown if relevant. Key points should be detailed at the end of the procedure. 5) Organ-specific: type of approach and bilateral audiometry should be specified in otology. Coronal plane computed tomography scans should be shown in endonasal surgery. It is recommended to show pre- and postoperative videos in voice surgery and preoperative drawings and photos of scars in plastic surgery, as well as the ventilation method in airway surgery. CONCLUSIONS: International recommendations have been determined to assist in the creation and standardization of educational surgical videos in otolaryngology and head and neck surgery.

Prevalence of sleep abnormalities and their association among hypothyroid patients in an Indian population.

OBJECTIVE: To estimate the prevalence of sleep abnormalities and their association with hypothyroidism and metabolic risk factors in a relatively lean urban South Indian population. METHODS: This population-based, cross-sectional study was carried out in the urban population of Chennai, one of the largest metropolitan cities of India. Phase 1 was conducted in the field and involved a door-to-door survey of 26,000 individuals. In phase 2, every tenth subject recruited in phase 1 (n=2600) was invited to our centre for detailed anthropometric and biochemical measurements. For the current study, a subset of 358 subjects with positive family history of hypothyroidism was randomly selected. A validated questionnaire assessing various sleep abnormalities (snoring, daytime sleepiness, lack of refreshing sleep and number of hours of sleep) was administered. Anthropometric and biochemical measurements were obtained to assess metabolic risk factors including thyroid status. RESULTS: Snorers were more often male, older, smokers and had higher BMI, neck circumference, blood pressures, and hypothyroidism. Out of 358 patients, 133 had impaired thyroid function (37.1%) and 64 patients had both snoring and impaired thyroid function (17.8%). Subjects with daytime sleepiness had higher BMI and neck obesity. The overall prevalence of snoring and daytime sleepiness was 52% and 64%, respectively. Both sleep measures were associated with hypothyroid status. Metabolic syndrome was significantly associated with snoring even after adjusting for age, sex, family history of hypothyroidism, physical activity, smoking and alcohol. CONCLUSIONS: The prevalence of snoring and daytime sleepiness is high among urban South Indians who are relatively lean. Both disorders are associated with hypothyroidism, although these associations were stronger in those with obesity. Based on our case prevalence and the other reports cited previously, we can reasonably conclude that thyroid screening of sleep clinic patients is essential.

Magnet migration in a cochlear implantee - a serendipitous diagnosis.

The successful outcome of a cochlear implant habilitation program depends upon a multitude of vital factors, including the avid cooperation of the cochlear implantee, committed participation of the parents/family members and total dedication of the habilitation team of implant audiologists and auditory verbal therapists. In a rare situation, where the implantee's performance is suboptimal or poor inspite of successful implantation, anxious moments engulf the parents and the implant team, with the morbid fear of a device failure lingering at the back of their minds. We report such an incident in a 13-year-old cochlear implantee, who was an excellent cochlear implant performer for 8 years, following which she had rapid deterioration of her auditory verbal skills within the next few weeks. The hidden etiology, was the inconspicuous migration of the internal magnet of the Receiver-Stimulator Coil placed in the mastoid temporal bone of her skull, due to unexplained reasons. We share our experience with the diagnosis and management of this condition and review the existing world literature on this rarely reported entity.

Totally implantable hearing aid surgical technique and the first Indian experience with Envoy esteem.

Hearing aids are the principal means of auditory rehabilitation for patients with moderate to severe sensorineural hearing loss. Although technical improvements and modifications have improved the fidelity of conventional aids, hearing aids still have many limitations. Implantable hearing aids offer patients with hearing loss several potential advantages over conventional hearing aids. This presentation will highlight our first experience, the indications, the procedure, the advantages and the current status of totally implantable hearing aids.
