Clade‐wide morphological and functional variation of the sauropsid columella
The Anatomical Record, EarlyView.Abstract The columella (=stapes) is the middle ear bone of reptiles that transmits vibrations from the environment to the inner ear. It has been shown to exhibit extensive interspecific morphological disparity in several clades; however, its morphological variation and associated functional consequences remain poorly described.

Quantifying Soft‐Surgery in Cochlear Implantation: Multimodal Data From 30 International Specialists
The Laryngoscope, EarlyView.Objective data from 30 specialist cochlear implant surgeons showed that surgical handling strongly influences intracochlear mechanical stress during implantation. Surgeons with fewer than 50 lifetime insertions performed significantly worse than more experienced colleagues, while self‐assessment did not reflect objective performance in any group ...

Pharmacokinetic Properties of Adenosine Amine Congener in Cochlear Perilymph after Systemic Administration [PDF]
, 2017 Noise-induced hearing loss (NIHL) is a global health problem affecting over 5% of the population worldwide. We have shown previously that acute noise-induced cochlear injury can be ameliorated by administration of drugs acting on adenosine receptors in ...

Hearing Preservation Rates After Cochlear Implantation Using Soft Surgery Techniques
The Laryngoscope, EarlyView.ABSTRACT Objectives To determine if hearing preservation rates after cochlear implantation varied over time with soft surgery techniques. Methods The hearing preservation rate over time in adult cochlear implant patients over 10 years was analyzed. The association between hearing preservation rate and sex, age, perioperative steroid dose, and type of ...

Subjective Visual Vertical Can be an Effective Tool to Evaluate Vestibular Function of Stapedotomy
World Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.ABSTRACT Objective To investigate if the subjective visual vertical/horizontal (SVV/SVH) can be used to evaluate the otolith organ of otosclerosis and stapedotomy. Design A total of 19 patients who were diagnosed with otosclerosis and underwent surgical treatment in our hospital were collected.

Noise-Induced Perilymph Fistula [PDF]
Ear, Nose & Throat Journal, 2006 Perilymph fistulae are difficult to diagnose because they present with a wide variety of signs and symptoms, they are associated with many etiologies, and they often mimic other conditions. In this article, we describe a case of perilymph fistula that featured one of its more rare causes: acoustic trauma—specifically, damage from a loud blast from the ...

Perilymph Gusher in Cochlear Implantation Surgery: An Algorithm for Management
World Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.ABSTRACT Objective Perilymph leak is considered a major complication of cochlear implantation (CI) surgery and can lead to surgical difficulties and postoperative morbidities. This study is aimed to formulate an algorithm for better management of perilymph leak in cases of CI. Methods This is a retrospective study conducted in our tertiary institute on
