Seven-Year Revision Rates for Cochlear Implants in Pediatric and Adult Populations of an Integrated Healthcare System.

Objective: We assessed three cochlear implant (CI) suppliers: Advanced Bionics, Cochlear Limited, and MED-EL, for implant revision requiring reoperation after CI placement.

Study Design: Retrospective cohort study of integrated-health-system database between 2010 and 2021. Separate models were created for pediatric (age <18) and adult (age ≥18) cohorts.

Single-staged resections and 3D reconstructions of the nasion, glabella, medial orbital wall, and frontal sinus and bone: Long-term outcome and review of the literature.

Background: Aesthetic facial appearance following neurosurgical ablation of frontal fossa tumors is a primary concern for patients and neurosurgeons alike. Craniofacial reconstruction procedures have drastically evolved since the development of three-dimensional computed tomography imaging and computer-assisted programming. Traditionally, two-stage approaches for resection and reconstruction were used; however, these two-stage approaches have many complications including cerebrospinal fluid leaks, necrosis, and pneumocephalus.

Management of the incus body in ossiculoplasty.

Objective: (1) Evaluate the sound transfer impact of removal of the incus body in ossicular chain reconstruction (OCR) using an incus strut prosthesis. (2) Provide basic science data to assist clinical decision making in ossiculoplasty.

Study Design: Basic science.

Low-dose D-methionine and N-acetyl-L-cysteine for protection from permanent noise-induced hearing loss in chinchillas.

Objective: Despite efforts at public health awareness and stringent industrial standards for hearing protection, noise-induced hearing loss (NIHL) remains a formidable public health concern. Although many antioxidants have proven to be beneficial in the laboratory for prevention of permanent NIHL, low-dose combinations of compounds with different biochemical mechanisms of action may allow long-term administration with fewer side effects and equal efficacy. The mixture of D-methionine and N-acetyl-L-cysteine administered at levels less than 10% of standard dosing has not been previously reported.

Effects of tympanomeatal blunting on sound transfer function.

Objective: (1) To measure the peak-to-peak displacement of the round window membrane (RWM) prior to blunting procedure. (2) To evaluate the impact of blunting the anterior tympanomeatal angle (ATA) on middle ear sound transfer function.

Study Design: Basic science study.

Prognostic assessments of medical therapy and vestibular testing in post-traumatic migraine-associated dizziness patients.

Objective: The aim of this study was to characterize our clinical population of patients suffering with post-traumatic migraine-associated dizziness (PTMAD) and determine any associations with medical interventions and vestibular testing metrics to help predict response to treatments.

Study Design: Retrospective chart review.

Setting: Tertiary referral center.

Blast exposure: vestibular consequences and associated characteristics.

Objective: To characterize vestibular and related symptoms seen after blast exposure.

Study Design: Prospective single-subject design.

Settings: Tertiary care facility and military field hospital.

Blunt and blast head trauma: different entities.

Mild traumatic brain injury (mTBI) caused by blast-related and blunt head trauma is frequently encountered in clinical practice. Understanding the nuances between these two distinct types of injury leads to a more focused approach by clinicians to develop better treatment strategies for patients. In this study, we evaluated two separate cohorts of mTBI patients to ascertain whether any difference exists in vestibular-ocular reflex (VOR) testing (n = 55 enrolled patients: 34 blunt, 21 blast) and vestibular-spinal reflex (VSR) testing (n = 72 enrolled patients: 33 blunt, 39 blast).

Distribution of PLGA nanoparticles in chinchilla cochleae.

Objectives: To study the distribution of polylactic/glycolic acid-encapsulated iron oxide nanoparticles (PLGA-NPs) in chinchilla cochleae after application on the round window membrane (RWM).

Study Design And Setting: Six chinchillas (12 ears) were equally divided into controls (no treatments) and experimentals (PLGA-NP with or without magnetic exposure). After 40 minutes of PLGA-NP placement on the RWM, perilymph was withdrawn from the scala tympani.

Posttraumatic balance disorders.

Head trauma is being more frequently recognized as a causative agent in balance disorders. Most of the published literature examining traumatic brain injury (TBI) after head trauma has focused on short-term prognostic indicators and neurocognitive disorders. Few data are available to guide those individuals who see patients with balance disorders secondary to TBI.

Review of pharmacological therapy for tinnitus.

This article provides a review of studies investigating the pharmacological treatment of tinnitus. Tinnitus continues to be a significant and costly health problem without a uniformly accepted treatment. A wide variety of studies exploring prescription, supplement, and vitamin therapies are assessed for efficacy of treatment and for establishing consistencies in symptom definition, assessment, and outcome measures.

NAC for noise: from the bench top to the clinic.

Noise-induced hearing loss (NIHL) is an important etiology of deafness worldwide. Hearing conservation programs are in place and have reduced the prevalence of NIHL, but this disorder is still far too common. Occupational and recreational pursuits expose people to loud noise and ten million persons in the US have some degree of noise-induced hearing impairment.

Delivery of drugs to the inner ear.

Purpose Of Review: Inner ear delivery of medicines has been a rapidly expanding field in otolaryngology. This technique provides a minimally invasive way of managing a number of otolaryngologic diagnoses and promises to provide a therapeutic option for previously untreatable disorders. The purpose of this review is to examine the literature that has been published recently (since January of 2005) in this field and to explore how this new literature has impacted on current practices.

The role of vestibular rehabilitation in the treatment of Meniere's disease.

Objective: To study the role of vestibular rehabilitation is treating patients with Meniere's disease.

Methods: We examined all Meniere's patients presenting to our tertiary care specialized vestibular clinic during a 1-year period. All patients underwent a standardized history and physical examination, a complete auditory-vestibular test battery, and a set of physical therapy tools to measure balance function.

Sustained-release devices in inner ear medical therapy.

Inner ear medical therapy has been gaining increasing popularity during the last 2 decades. Despite the increased use of this therapy,basic questions regarding this type of treatment have not been answered. The authors have used a variety of sustained-release devices in the laboratory to begin to answer some of these basic questions.

Sustained-release delivery of leupeptin in the chinchilla: hearing results.

Transtympanic medical therapy is becoming an increasingly popular modality for the treatment of "inner-ear disorders." While investigators continue to examine the best dosing paradigms for gentamicin in the treatment of Ménière's disease and for steroids in the treatment of hearing loss, they have also begun to focus on the use of other agents. In particular, transtympanic therapy has been advocated as a plausible route for the treatment of tinnitus.
