Evaluation of a Less Invasive Cochlear Implant Surgery in Mutations Provoking Deafblindness.

Cochlear implantation (CI) for deafblindness may have more impact than for non-syndromic hearing loss. Deafblind patients have a double handicap in a society that is more and more empowered by fast communication. CI is a remedy for deafness, but requires revision surgery every 20 to 25 years, and thus placement should be minimally invasive.

Effects of Rhinoplasty on Labyrinthine Function.

Background: Rhinoplasty is a common surgical procedure that is requested and accepted by patients for cosmetic and functional reasons. Osteotomies are performed on nasal bone, maxillary crest, or vomer to fix the deviations of the nasal dorsum or septum. During the percussion of the osteotomes with the surgical mallet, the vibration energy diffuses to the cranium.

Utilizing ethnic-specific differences in minor allele frequency to recategorize reported pathogenic deafness variants.

Ethnic-specific differences in minor allele frequency impact variant categorization for genetic screening of nonsyndromic hearing loss (NSHL) and other genetic disorders. We sought to evaluate all previously reported pathogenic NSHL variants in the context of a large number of controls from ethnically distinct populations sequenced with orthogonal massively parallel sequencing methods. We used HGMD, ClinVar, and dbSNP to generate a comprehensive list of reported pathogenic NSHL variants and re-evaluated these variants in the context of 8,595 individuals from 12 populations and 6 ethnically distinct major human evolutionary phylogenetic groups from three sources (Exome Variant Server, 1000 Genomes project, and a control set of individuals created for this study, the OtoDB).
