Objective: The recommended readability of health education materials is at the sixth-grade level. Artificial intelligence (AI) large language models such as the newly released ChatGPT4 might facilitate the conversion of patient-education materials at scale. We sought to ascertain whether online otolaryngology education materials meet recommended reading levels and whether ChatGPT4 could rewrite these materials to the sixth-grade level.

Objective: The power output from carbon dioxide (CO) laser fibers has the potential to be diminished if there are any bends along its course, which may alter the effect the laser has on the target tissue. In this study, we assess how bending of CO laser flexible fiber assemblies affects the energy output measured at the end of the fiber.

Study Design: Laboratory study.

Introduction: Intralabyrinthine schwannomas, including the intracochlear variety, are rare benign tumors. They can cause a number of symptoms and have the potential to grow to involve other critical structures of the inner ear and skull base. While surgical resection is feasible, there is typically permanent hearing dysfunction as a result of resection and subsequent fibrosis.

Objective/hypothesis: Stapes surgery is occasionally complicated by an intraoperative tympanic membrane perforation (ITMP), traditionally indicating abortion of the procedure due to concerns for postoperative infection and sensorineural hearing loss (SNHL). This work examines outcomes and complications in completed primary stapes surgeries with and without ITMP.

Objective: Stapes surgery is highly successful in reducing or eliminating the audiometric air-bone gap (ABG) related to otosclerosis, and it can be performed under general anesthesia or local anesthesia with sedation. Literature on the relative outcomes of these 2 modalities is lacking. The purpose of this study was to compare hearing outcomes for these 2 modalities in a large patient population.

Purpose: To review surgical outcomes of stapes surgery for otosclerosis with persistence of the stapedial artery.

Materials And Methods: A retrospective case review of a tertiary neurotology referral center of patient with otosclerosis undergoing primary stapes surgery between 2010 and 2017 found to have a persistent stapedial artery. Stapedectomy was performed with or without cauterization of the stapedial artery.

We present two unique cases of myoclonus-induced objective tinnitus (OT), along with a comprehensive literature review on the topic. Primary goals include: explore the relationship between palatal myoclonus (PM) and middle ear myoclonus (MEM), highlight the embryologic, neurologic, and anatomical relationship between the involved peri-tubular muscles, exemplify the first case of OT which documents video evidence demonstrating the link between objective tinnitus and eustachian tube movement. Also, we discuss available treatment interventions and why they often do not fully resolve patients' symptoms.
