OBJECTIVE To evaluate hearing results and postoperative dizziness after stapedotomy with application of sodium hyaluronate gel (HG) to the oval window niche during fenestration of the footplate. STUDY DESIGN Case-control study comparing 27 stapedotomies with HG and 32 stapedotomies without HG. OUTCOME MEASURE Preoperative and postoperative audiometric data, postoperative dizziness (vertigo ...

This paper investigates how video game publishers’ choice of game release date is affected by the expected level of competition within the game’s product niche. We identify game niches by genre, age-appropriateness, a four week window cohort, publisher and console system. Our analysis is based on two different video game data sets, one based on industry sales data and the other featuring extens...

This note proposes a modification for TCP’s slow-start for use with TCP connections with large congestion windows. For TCP connections that are able to use congestion windows of thousands (or tens of thousands) of MSS-sized segments (for MSS the sender’s MAXIMUM SEGMENT SIZE), the current slow-start procedure can result in increasing the congestion window by thousands of segments in a single ro...

This paper proposes a memristor SPICE model using the Tukey window (or tapered cosine window) function. Compared with the previously proposed models based on the boundary function, the proposed model is resistant to numerical errors. From the SPICE result of a relaxation oscillator, we observe that the proposed model can be effectively used to minimise the effect of round-off errors.

Tinnitus is a common symptom for which few existing therapeutic approaches can produce reliable reduction or elimination. Chemical perfusion involves the delivery of medication directly into the inner ear via the round-window membrane. This report discusses the use of dexamethasone or gentamicin in 20 individuals who had inner ear diseases in which disturbing cochlear tinnitus was one of the sy...

Background: It is recognized that the size of tympanic membrane(TM) perforation is proportional to the magnitude of hearing loss, however, there is no clear consensus on the effect of the location (site) of the perforation on the hearing loss. Hence the study is set to investigate the relationship between the location of perforation on TM and hearing loss. Methods: A cross-sectional prospective...

OBJECTIVE To review the surgical procedures and outcomes in children with bilateral oval window aplasia (OWA). STUDY DESIGN Retrospective cohort review. SETTING Tertiary referral center. PATIENTS Children suffering from OWA between 1990 and 2010. INTERVENTION Vestibulotomy with ossiculoplasty (V-OPL) or round window vibroplasty (RWV). MAIN OUTCOME MEASURES Findings at radiology and su...

OBJECTIVE/HYPOTHESIS Previous reports have documented the feasibility of utilizing electrocochleographic (ECoG) responses to acoustic signals to assess trauma caused during cochlear implantation. The hypothesis is that intraoperative round window ECoG before and after electrode insertion will help predict postoperative hearing preservation outcomes in cochlear implant recipients. STUDY DESIGN...

Introduction Most implantable hearing aids currently available were developed to compensate the sensorineural hearing loss by driving middle ear structures (e.g., the ossicles). These devices are successfully used in round window (RW) stimulation clinically, although this was initially not the intended use. Here, a novel microactuator, specifically designed for RW stimulation, was tested in hum...
