Intraoperative Electrical Stapedius Reflex Testing to Monitor Cochlear Nerve Integrity during Simultaneous Vestibular Schwannoma Resection and Cochlear Implantation.

Objective: To compare the utility of intraoperative electrically evoked auditory brainstem response (eABR) and electrically evoked stapedial reflex testing (eSRT) for cochlear nerve integrity monitoring during simultaneous translabyrinthine resection of vestibular schwannoma (VS) and cochlear implantation.

Study Design: Historical cohort study.

Setting: Tertiary academic referral center.

Outcomes with transcutaneous bone conduction implants in patients with mixed hearing loss.

Objective: To evaluate audiological outcomes of transcutaneous devices among individuals with mixed hearing loss (MHL) who underwent implantation with the Cochlear™ Osia® and Med-El Bonebridge™ devices.

Methods: Adults with MHL in at least one ear, including a best bone conduction (BBC) threshold of 30 dB HL or poorer, and air-bone gaps of 15 dB HL or more at one or more frequencies were implanted with the Cochlear™ Osia® or Med-El Bonebridge™ devices for MHL. Four-frequency pure tone average (PTA) was calculated for aided thresholds and compared to preoperative PTAs for BBC thresholds.

Associations of Microvascular Risk Factors with Sporadic Vestibular Schwannoma Outcomes Following Stereotactic Radiosurgery.

Objective: Stereotactic radiosurgery (SRS) is increasingly used for small-to-medium-sized sporadic vestibular schwannoma (VS) and is associated with good tumor control and low-risk of adverse radiation-associated events. The exact mechanism of VS tumor control is unknown but may relate to microvascular hyalinization and resultant tumoral ischemia. This study examined associations of microvascular risk factors with outcomes following SRS.
