Preoperative Differences in Intracranial Facial Versus Vestibular Schwannomas: A Four Nerve Assessment.

Objectives: Assesses whether preoperative functional testing can distinguish vestibular schwannomas from facial nerve schwannomas medial to the labyrinthine segment.

Study Design: Retrospective cohort.

Methods: Retrospectively review surgically managed intracranial facial and vestibular schwannomas between January 2015 and December 2019 at two tertiary care centers.

Vestibular function in cochlear implantation: Correlating objectiveness and subjectiveness.

Objective: To evaluate vestibular function before and after cochlear implantation (CI) STUDY DESIGN: A prospective descriptive study.

Material And Methods: Thirty consecutive patients with profound sensorineural hearing loss undergoing CI. Objective assessment of vestibular function was performed with the caloric test and video head impulse test (vHIT) in patients before and after CI.

Subjective and objective findings in patients with true dehiscence versus thin bone over the superior semicircular canal.

Objective: To compare subjective and objective findings between patients with true dehiscence versus thin bone over the superior semicircular canal (SSC).

Study Design: Retrospective case series.

Setting: Tertiary referral center.

Communication in noise with acoustic and electronic hearing protection devices.

The purpose of the present study was to evaluate communication ability in noise at two signal presentation levels when using acoustic and electronic hearing protection devices (HPDs). Fourteen normal hearing subjects were fitted binaurally with custom acoustic HPDs (ER-15) and custom electronic HPDs (Starkey SA T9). Probe microphone measurements were obtained on 28 ears for three experimental conditions (open ear, acoustic HPD, electronic HPD) at four input signal levels (60, 70, 80, 90 dB SPL).
