Quality of life in the management of small vestibular schwannomas: Observation, radiotherapy and microsurgery.

Objective: The aim of this study was to compare quality of life (QOL) in small unilateral vestibular schwannoma (VS) patients managed by microsurgery, radiotherapy or observation.

Study Design: A retrospective chart review.

Methods: The study included a total of 142 patients with VS stage 1 or 2 according to the Koos classification and treated between January 2004 and December 2015.

Local gene therapy durably restores vestibular function in a mouse model of Usher syndrome type 1G.

Our understanding of the mechanisms underlying inherited forms of inner ear deficits has considerably improved during the past 20 y, but we are still far from curative treatments. We investigated gene replacement as a strategy for restoring inner ear functions in a mouse model of Usher syndrome type 1G, characterized by congenital profound deafness and balance disorders. These mice lack the scaffold protein sans, which is involved both in the morphogenesis of the stereociliary bundle, the sensory antenna of inner ear hair cells, and in the mechanoelectrical transduction process.

Hypervulnerability to Sound Exposure through Impaired Adaptive Proliferation of Peroxisomes.

A deficiency in pejvakin, a protein of unknown function, causes a strikingly heterogeneous form of human deafness. Pejvakin-deficient (Pjvk(-/-)) mice also exhibit variable auditory phenotypes. Correlation between their hearing thresholds and the number of pups per cage suggest a possible harmful effect of pup vocalizations.

Lateral semicircular canal fistula in cholesteatoma: diagnosis and management.

The objective of this retrospective study was to present the authors' experience on the management of labyrinthine fistula secondary to cholesteatoma. 695 patients, who underwent tympanoplasty for cholesteatoma, in a University Hospital between 1993 and 2013 were reviewed, to select only those with labyrinthine fistulas. 42 patients (6%) had cholesteatoma complicated by fistula of the lateral semicircular canal (LSCC).
