Objectives: Recently, determinants of frailty have become an increasingly recognized perioperative risk stratification tool. This study examines the predictive value of a 5-factor modified frailty index (mFI-5) on perioperative morbidity and mortality in patients undergoing otologic surgery, with a subgroup analysis based on surgery site.
Study Design: Cross-sectional analysis.
Setting: National surgical quality improvement program dataset 2005-2019.
Patients: Current procedural terminology (CPT) codes were used to identify patients undergoing all otologic surgeries.
Interventions: Otologic surgeries as indicated by CPT codes, including external ear, middle ear/mastoid, implants, and inner ear/facial nerve subgroups.
Main Outcome Measures: Primary outcomes examined in this study included rates of overall complications and life-threatening complications within 30 days after surgery. Overall complications included superficial surgical site infections (SSI), deep incisional SSI, readmission, deep vein thrombosis, life-threatening complications, and mortality. Life-threatening complications included those classified as Clavien-Dindo grade IV: cerebrovascular accident, mechanical ventilation for more than 48 hours, reintubation, pulmonary embolism, acute renal failure, cardiac arrest, and myocardial infarction.
Results: A total of 16,859 patients who underwent otologic surgery were identified, resulting in a cohort that was 47.5% male with an average age of 47.6 years (17.1 SD). Multivariable regression analysis of the entire cohort demonstrated a score of 3 or more on the mFI-5 was independently predictive of all postoperative complications (odds ratio (OR): 2.02, < 0.0001). However, subgroup analysis showed that only "external ear" surgery correlated with mFi-5 (OR 8.03, = 0.013).
Conclusions: Higher frailty scores as measured by the mFI-5 correlate with postoperative morbidity and mortality after otologic surgery, though subgroup analysis reveals an association only with cases performed on the external ear. These findings suggest that for most otologic surgery, the mFI-5 frailty score is not predictive of postoperative complications.

<b>Introduction:</b> The exposure to unsafe sound levels is considered a risk factor for developing noise-induced hearing loss (NIHL). Personal listening devices (PLDs) represent a common source of recreational noise among young adults. First changes of NIHL could be detected at extended high frequencies (EHFs).

Novel therapeutic delivery systems and delivery methods to the inner ear are necessary to treat hearing loss and inner ear disorders. However, numerous barriers exist to therapeutic delivery into the bone-encased and immune-privileged environment of the inner ear and cochlea, which makes treating inner ear disorders challenging. Nanoparticles (NPs) are a type of therapeutic delivery system that can be engineered for multiple purposes, and posterior semicircular canal (PSCC) infusion is a method to directly deposit them into the cochlea.

Objectives: To evaluate the otolaryngology surgical capacity in Harare, Zimbabwe by analyzing procedural volumes across four hospitals, one private and three public, from 2019 to 2022.
Methods: A retrospective review of hand-written surgical case logs was conducted at Harare Eye, Ear, Nose, and Throat Institute (HEENT), Parirenyatwa Group of Hospitals (PGH), Sally Mugabe Children's Hospital (SMCH), and Sally Mugabe Adult's Hospital (SMAH). Patient age and surgical intervention for all otolaryngology surgeries performed in the operating room from 2019 to 2022 were recorded.
