This study was designed to verify an eventual perilymphatic fistula (PLF) in 264 patients with sensorineural hearing loss (SNHL) and/or vertigo. The patients were exposed to a low-frequency sound stimulation (LFS) on posturography to objectively test Tullio's phenomenon and Hennebert's sign. Endoscopes with 5 degree and 25 degree of visual angle and an outer diameter of 1.7 mm were used. The ro...

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...

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...
