Counter, S. Allen, Leo H. Buchanan, Fernando Ortega, Anthony B. Jacobs, and Göran Laurell. Middle ear function and pathophysiology in Andean children living at high altitudes. High Alt Med Biol 00:000-000, 2017.-The extent of altitude-related middle ear disorders in children native to high altitudes is unclear. This study examined middle ear pathophysiology in two groups of children living in high-altitude Ecuadorian Andean communities by investigating middle ear pressure (MEP), tympanic membrane compliance (TMC), and ear canal volume (ECV) using tympanometry, and by otological examination...

OBJECTIVE: Intimate partner violence against women is a major health problem in most nations, but to date, there has been little awareness of the extent or seriousness of this issue in Jordan. Forensic medical practitioners play a significant role in diagnosing, evaluating and reporting these cases. The Jordanian judicial system is dependent on forensic reports. This study aims to assess the role of forensic medicine in evaluating the physical injuries sustained by women who are abused by their husbands...

Aim of the present study is to evaluate the long term results of ossiculoplasty using titanium clip prosthesis. A retrospective analysis with prospective follow-up has been done including for all patients who had a Clip-PORP implanted between the years 2002-2013. Following this, audiometric hearing results were measured with clinical examination including otoscopy and quality of life evaluation using Glasgow benefit inventory. 48 patients (51 ears, 29 men, 19 women, average age 44.1 years) received followed up after an average duration of 6...

INTRODUCTION: Long-term space flight induces a near visual acuity change in approximately 50% of astronauts. In some crew members, postflight cerebrospinal fluid (CSF) opening pressures by lumbar puncture are as high as 20.9 mmHg who demonstrated optic disc edema. CSF communicates through the cochlear aqueduct to affect perilymphatic pressure and tympanic membrane motion. We hypothesized that 50 mmHg of lower-body negative pressure (LBNP) during 15° head-down tilt (HDT) would mitigate elevations in internal jugular vein cross-sectional area (IJV CSA) and intracranial pressure (ICP)...

This manuscript intends to review types, pathogenesis, associated risk factors, and potential methods of prevention and treatment of the retraction pockets in adults and children. The importance of retraction pockets (RP) lies in loss of original histological and anatomical structure which is associated with development of ossicular chain erosion, cho¬lesteatoma formation and potentially life threatening complications of cholesteatoma. The trans-mucosal exchange each gas in the middle ear (ME) is towards equalizing its partial pressures with the partial pressure in the environ¬ment...

OBJECTIVE: This study investigated the influence of the degree of bleeding from the remnant eardrum on the spontaneous healing of human traumatic tympanic membrane perforations (TMPs). STUDY DESIGN: A case series with chart review. SETTING: A tertiary university hospital. MATERIALS AND METHODS: The clinical records of traumatic TMP patients who met the case selection criteria were retrieved and categorized into two groups based on the documented degree of bleeding from the remnant eardrum: with and without bleeding...

INTRODUCTION: Boric acid, which has antiseptic and acidic properties, is used to treat external and middle ear infections. However, we have not found any literature about the effect of boric acid powder on middle ear mucosa and inner ear. OBJECTIVE: The purpose of this study is to investigate possible ototoxic effects of boric acid powder (BAP) on cochlear outer hair cell function and histological changes in middle ear mucosa in a rat animal model. METHODS: Twenty healthy, mature Wistar albino rats were used in this study...

HYPOTHESIS: To examine the cellular events following induced superficial lesions of the human tympanic membrane (TM). Such information could lead to enhanced appreciation of repair mechanisms and novel strategies to restore TM perforations. BACKGROUND: Persistent perforation of the TM in chronic otitis media is a major global health problem and frequently necessitates surgical intervention. Most TM perforations heal spontaneously and swiftly, but sometimes healing fails...

Hemangiomas are very common tumors characterized by large numbers of vessels filled with blood. Capillary hemangioma is the most common type of hemangioma, whereas capillary hemangiomas of the tympanic membrane and external auditory canal are extremely rare vascular tumors. The authors present capillary hemangioma of the tympanic membrane and external auditory canal in a 54-year-old woman with right-sided aural fullness for 3 months. Under local anesthesia, the mass was resected by transcanal microscopic surgery...

Lightning strike can cause fatal or nonfatal injuries. Some nonfatal injuries are associated with otological symptoms and findings. Conductive hearing loss due to rupture of the tympanic membrane is the most common audiovestibular lesion of lightning strike. Various forms of sensorineural hearing loss and dizziness have also been reported. Presently described are 3 cases of lightning strike injury. First patient had mid-frequency hearing loss in right ear and high frequency sensorineural hearing loss in left ear...
