BACKGROUND: In the supine position, forced-air warming is more effective on the lower body than on the upper body to prevent intraoperative hypothermia. However, it is unknown in the lateral decubitus position. We thus compared forced-air warming on the upper and lower bodies in the lateral position. METHODS: Patients (n=123) were randomised to receive forced-air warming on the upper body or lower body during thoracoscopic surgery in the lateral position. We measured the nasopharyngeal temperature at 0, 30, 60, 90, and 120 min after lateral positioning during surgery and the infrared tympanic membrane temperature at 0, 30, 60, 90, and 120 min after surgery...

OBJECTIVES: Although a number of methods have been attempted to improve securing the graft, packing gelfoam in the middle ear cavity cannot be avoided, which could obstruct the tympanic ostium of the Eustachian tube and affect inner ear function. Myringoplasty using tissue adhesive has gained traction because tissue adhesives can effectively stabilise the graft and act as scaffolding to improve the graft uptake. The aim of this prospective study was to explore myringoplasty using cyanoacrylate glue with no packing in the middle ear cavity for the repair of subtotal tympanic membrane (TM) perforations...

INTRODUCTION: The high incidence of chronic otitis media with effusion and Eustachian tube dysfunction in children with Down syndrome (DS) may predispose them to cholesteatoma formation. Establishing the diagnosis, choosing the appropriate operative intervention, and post-operative care can be challenging. OBJECTIVE: To describe management strategies for cholesteatoma diagnosis, surgical treatment, and post-operative management in children with Down syndrome. METHODS: Retrospective case series of 14 patients (17 total ears) with Down syndrome diagnosed with cholesteatoma over a 9-year period...

OBJECTIVES: Tele-otoscopy has been validated for tympanostomy surveillance and remote diagnosis when images are recorded by trained professionals. The CellScope iPhone Otoscope is a device that may be used for tele-otoscopy and it enables parents to record their children's ear examinations and send the films for remote physician diagnosis. This study aims to determine the ability to diagnose, and the reliability of the diagnosis when utilizing video exams obtained by a parent versus video exams obtained by an otolaryngologist...

OBJECTIVES: To determine the value of tympanostomy tubes (TTs) in the management of serous otitis media (SOM) and the risk factors for SOM recurrence. METHOD: This single-centre cohort study was performed in the University hospital of Amiens, France; and concerned 215 under-12 children having undergone at least one bilateral TT (Shepard grommet-type) placements for SOM. RESULTS: The mean TT retention time was 10 months. SOM recurred in 79 children (62...

OBJECTIVE: The feasibility of TEES in dealing with pediatric middle ear disease is still under investigation. The goal of this study was to compare anatomical dimensions of the EAC between children and adults, and to analyze the anatomic applicability of TEES in children. METHODS: Forty pediatric (18 years old and younger) and 20 adult patients who received TB-HRCT to evaluate middle ear conditions were enrolled from December 2010 to December 2015. Dimensions including the diameters of the EAC orifice, isthmus and tympanic membrane annulus, the length of EAC, the height of the middle ear, and the angle between tympanic membrane and EAC axis were determined according to the TB-HRCT data...

BACKGROUND: The serotonergic system is known to be involved in control of post-anesthetic shivering. Our hypothesis was that prophylactic granisetrone (serotonin antagonist) might reduce incidence of post- spinal anesthesia shivering in cesarean section. METHODS: Parturient scheduled for elective Caesarean delivery under spinal anesthesia were allocated to receive 0.9% saline (Group I, n = 71), 1 mg granisetron (Group II, n = 69), or 0.7 mg granisetron (Group III, n = 72) before the spinal block...

BACKGROUND: The English language literature finds no clear protocols for otologic surgery for HIV+ patients. OBJECTIVE: To demonstrate that simple tympanoplasty and type III tympanoplasty in HIV+ patients with CD4 >400 cells/cc results in tympanic membrane closures and hearing improvements equivalent to the same procedures in controls. MATERIALS AND METHODS: This retrospective review documents the otologic conditions and operative results of 32 HIV+ patients and 32 controls...

Objective: We aimed to examine the effect of topical dexamethasone by otomicroscopic and histologic examinations for preventing myringosclerosis induced by myringotomy in rat tympanic membranes. Methods: Twenty-one Sprague Dawley rats (42 ears) were randomly divided into the following three groups after otomicroscopic examinations: experimental surgical group (5 rats), control group (8 rats), and study group (8 rats). The rats of all the groups underwent myringotomy in both tympanic membranes...

Tympanic membrane displacements (TMDs) are used to non-invasively gauge inner-ear fluid pressure. Inner-ear fluid pressure equalizes with intracranial pressure (ICP) via the cochlear aqueduct and therefore TMDs can indirectly evaluate ICP. We studied the relationship between two TMD modalities, evoked and spontaneous. Evoked TMD is a reflex response to an auditory stimulus and the established stapes-footplate mechanism explains how evoked TMDs change with ICP. Spontaneous TMD refers to a pulsatile TMD waveform expressed in the form of pulse amplitudes (TMD-PAs), the origins of which are poorly understood...

OBJECTIVE: To compare stapes vibrations in different partial ossicular replacement prosthesis (PORP) applications. METHODS: Stapedial vibrations were measured on fresh frozen human temporal bones with laser Doppler vibrometry. Eight different types of common ossiculoplasty methods were compared regarding recovery of stapes vibrations in relation with the normal ossicular chain. The PORPs were divided into three groups: 1) PORPs with the lateral contact only with the tympanic membrane, 2) PORPs with lateral contact only to the malleus handle, and 3) PORPs with lateral contact with both the malleus handle and the tympanic membrane...

BACKGROUND: Chronic otitis media is described as a tympanic membrane perforation and ear discharge for more than six weeks duration. Ascending infection from the nasopharynx into the middle ear cleft has been attributed to prevent resolution of chronic otitis media. This research aims to determine the association between the microbiological flora of the nasopharynx with that of the middle ear in patients suffering from chronic (active) mucosal otitis media.. METHODS: Our study is a hospital-based cross-sectional survey...

OBJECTIVE: Older adults often have trouble adjusting to hearing aids when they start wearing them for the first time. Probe microphone measurements verify appropriate levels of amplification up to the tympanic membrane. Little is known, however, about the effects of amplification on auditory-evoked responses to speech stimuli during initial hearing aid use. The present study assesses the effects of amplification on neural encoding of a speech signal in older adults using hearing aids for the first time...

OBJECTIVE: We investigated the use of autologous platelet-rich plasma (PRP) to improve the success rate of fat graft myringoplasty in perforated tympanic membranes of rats. MATERIALS AND METHODS: A total of 20 healthy Wistar albino female rats were divided into two groups. In Group 1, the left tympanic membranes were perforated and grafted with a fat graft that was harvested from the inguinal region. In Group 2, the left tympanic membranes were perforated, and a fat graft was also harvested from the inguinal region...
