The Intraosseous Subarcuate Loop of Anterior Inferior Cerebellar Artery: Anatomic Management Guide, Single-Center MRI Study, and Scoping Review.

Background And Objectives: The intraosseous subarcuate loop (SL) is a unique variant of the anterior inferior cerebellar artery (AICA), where a loop of the artery is trapped in the petrous bone's subarcuate fossa (SF). Recognizing this variant is crucial for planning cerebellopontine angle (CPA) surgeries; however, data regarding its frequency and management vary in the published literature. A cohort from a single center was studied using MRI to assess its prevalence, and the findings were compared with the existing literature.

A Multi-Center Study of Ossiculoplasty Hearing Outcomes and a Grading Scale of Ear Environment Risk.

Objective: To determine which ear environment risk factors impact ossiculoplasty hearing outcomes and to generate a statistically-valid grading system for ossiculoplasty outcome reporting.

Study Type: Retrospective case series.

Methods: A multi-institutional database was generated from cases performed between 2011 and 2019.

Mild-to-moderate psoriasis is associated with subclinical inflammation in the duodenum and a tendency of disturbed intestinal barrier.

Psoriasis is a chronic skin disease occasionally associated with abdominal symptoms and IBD. We aimed to characterize intestinal immune cells and the integrity of the intestinal barrier in psoriasis. Biopsies from the duodenum and colon were analyzed by flow cytometry and immunohistochemistry for the presence and activation status of different immune cell populations.

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.

Cochlear Implantation With Sporadic Inner Ear Schwannomas: Outcomes in 106 Patients From an International Multi-Institutional Study.

Objective: To evaluate cochlear implant speech perception among patients with sporadic inner ear schwannoma who underwent ipsilateral implantation.

Study Design: Retrospective multi-institutional cohort study.

Setting: Eleven tertiary academic medical centers across Germany, Denmark, and the United States.
