BACKGROUND: It is a known fact that bacterial or viral acute otitis media occurs more frequently in the winter months. Only a few older studies on seasonal differences in middle ear findings are available. These studies are based solely on tympanography, without correlation to intraoperative middle ear findings. This study addresses the question of whether seasonal differences can be found in the preoperative tympanogram and in the corresponding intraoperative findings in children with chronic middle ear problems...

Otitis media with effusion (OME) is a common disease in childhood. There is no consensus on the optimal therapeutic option for OME. Considering the known efficacy of acetylcysteine (AC) and azithromycin (AZ) in the treatment of middle ear mucosa, the aim of the study was to assess their efficacy in the management of chronic OME. The study included 90 children with OME, both ears. They are divided into three groups of 30 children. Group 1 (AC) patients were treated with acetylcysteine per os, 3 × 100 mg, for 3 weeks; group 2 (AZ) with body weight adjusted dose of azithromycin for 3 days; and group 3 (AC + AZ) with a combination of acetylcysteine and azithromycin at doses described above...

INTRODUCTION: Oral Submucous fibrosis (OSMF) is a chronic insidious disease of oral mucosa that occurs due to areca-nut chewing, consumption of chillies, autoimmunity and genetic predisposition. The disease starts with burning sensation and inability to tolerate spicy foods with gradual reduction in mouth opening due to fibrosis of the oral mucosa. The extension of fibrosis into the naso pharynx leads to reduction in hearing efficiency. It is a potentially malignant lesion and can transform into oral cancer...

BACKGROUND: Middle ear adenoma with neuroendocrine differentiation (MEA-ND), also known as carcinoid tumor of the middle ear, is an extremely rare neoplasm, especially when located within the tympanic cavity. To the best of our knowledge, this represents the first pediatric case of a MEA-ND described in Europe. Excluding the present case, only three other pediatric cases of this disease have been published globally. CASE REPORT: We report on a 15-year-old female patient who presented with conductive hearing loss of the right ear...

BACKGROUND: Gas pressure balance is essential for maintaining normal middle ear function. The mucosal surfaces of the middle ear, the mastoid air cell system (MACS), and the Eustachian tube (ET) play a critical role in this process; however, the extent that each of these factors contributes to overall middle ear ventilation is unknown. The objective of this study was to determine if the ET alone can maintain normal middle ear pressure without the MACS. To do this, we reviewed subjects who had their MACS completely removed with translabyrinthine (TL) surgery for vestibular schwannoma...

We conducted a prospective, observational study over a 3-year period to compare the clinical, functional, and surgical findings in children with chronic bilateral otitis media with effusion who underwent one of three different types of treatment. Our study population was made up of 150 patients-79 boys and 71 girls aged 24 to 84 months-who were randomly assigned to one of the three treatment groups of 50 patients each. One group was treated with myringotomy, tympanostomy tube insertion, and adenoidectomy (T+A group); another with a combination of physical conservative treatment and adenoidectomy (P+A group); and the third with physical conservative treatment alone (P-only group)...

PURPOSE: The purpose of this study was to present normative data of tympanometric measurements of wideband acoustic immittance and to characterize wideband tympanograms. METHOD: Data were collected in 84 young adults with strictly defined normal hearing and middle ear status. Energy absorbance (EA) was measured using clicks for 1/12-octave frequencies (0.236 to 8 kHz), with the ear canal air pressure systematically varied (+200 to -300 daPa). In 40 ears, 7 consecutive trials and a trial of clinical 226-Hz acoustic admittance (Ya) tympanometry followed...

This study evaluated the ability of wideband absorbance (AB) to predict the presence of middle-ear effusion (MEE) in ears with a flat (type B) 226 Hz tympanogram (TG). AB measures were obtained in a no MEE group of 8 ears with a flat TG and a MEE group of 19 ears also with a flat TG. AB was significantly small at frequencies 2 and 4 kHz in the MEE group than in the no MEE group. Based on our results, it appeared that AB could detect MEE with higher specificity than conventional tympanometry. The presence or absence of MEE could be distinguished based on the average AB using 1, 2, and 4 kHz, with 40% as the cutoff point...

Myringotomy with the insertion of ventilation tubes is the most frequent surgical procedure performed in children, and the appearance of myringosclerosis is one of its most frequent long-term complications. The objective of this study is to identify clinical factors and technique variations that may have a relation with the appearance of myringosclerosis, after tube insertion. Patients submitted to myringotomy with transtympanic short-term tube insertion were studied in a longitudinal prospective and analytical cohort study with the prospective randomized open, blinded endpoint (PROBE) methodology, to study the influence of the location of myringotomy (anterior-inferior quadrant or posterior-inferior), directions of the incision (radial or non-radial) and aspiration or not of the middle ear...

OBJECTIVE: Children with Down syndrome (DS) have a high incidence of middle ear disorders and congenital abnormalities of the external, middle and inner ear. Energy reflectance (ER), a wideband acoustic immittance (WAI) measurement parameter, can measure the sound energy reflected or absorbed in the ear canal over a wider range of frequencies more efficiently and faster than conventional single-tone 226 Hz tympanometry. The aim of the present study was to compare the WAI measurements of children with DS with those of typically developing, normal-hearing children according to their tympanometric findings...

OBJECTIVE: Conventional treatment for acute otitis media mainly targets bacteria with antibiotics, neglecting to control for mediators of inflammation. Mediators of inflammation, such as leukotrienes, have been identified in patients with acute otitis media (AOM) or subsequent secretory otitis media (SOM). They can cause functional eustachian tube dysfunction or increase mucous in the middle ear, causing persistent SOM following AOM. The objective of the present study was to evaluate whether or not administration of pranlukast, a widely used leukotriene C4, D4, and E4 antagonist, together with antibiotics could inhibit the progression to SOM...

BACKGROUND Pathologies that alter the impedance of the middle ear may consequently modify the DPOAE amplitude. The aim of this study was to correlate information from 2 different clinical procedures assessing middle ear status. Data from DPOAE responses (both DP-Gram and DP I/O functions) were correlated with data from multi-component tympanometry at 1000 Hz. MATERIAL AND METHODS The subjects were divided into a double-peak group (DPG) and a single-peak group (SPG) depending on 1000 Hz tympanogram pattern. Exclusion criteria (described in the Methods section) were applied to both groups and finally only 31 ears were assigned to each group...
