The prognostic value of mucociliary clearance in predicting success in tympanoplasty

1993

AbstractMucociliary and equipressive eustachian tube functions have been studied, using saccharin solution (five per cent sodium saccharinate) and tubal manometry respectively, in 58 ears with chronic disease undergoing tympanoplasty. The position of the perforation site determines the results as the poorest results are obtained from the posterior ones, positive cases (47 per cent) and mean transport time (37.7 minutes), compared to the greater percentage of positive cases (86 per cent) and mean transport time (22.2 minutes) for anterior perforations.When both parameters are analysed together there is a direct relationship between normal equipressive function and normal mucociliary transpor…

[Treatment of sensorineural hearing loss in acute viral otitis media with intratympanic dexamethasone and hyaluronic acid in comparison with intraven…

2006

Background: Intratympanic dexamethasone with hyaluronic acid has shown to be an effective treatment of the inner ear damage in sudden hearing loss and Meniere's disease. It is not known yet if the same applies to the toxic inner ear damage in acute viral otitis media. Patients: Retrospectively, 26 patients who suffered from acute viral otitis media with sensorineural hearing loss were examined with regard to the improvement of their inner ear hearing loss. Twelve patients were treated with intravenous therapy only, consisting of hydroxyethylstarch, pentoxifylline and prednisolone. Fourteen patients additionally received intratympanic injections, consisting of dexamethasone and hyaluronic ac…

Bioactive Glass-Ceramics in Middle Ear Surgery An 8-Year Review

1988

An 8-year follow-up of Ceravital middle ear prostheses showed there was extremely good tolerance in the middle ear space. Incompatibility phenomena were not observed, and inflammatory reactions were neither caused nor supported by the implants. The tympanoplasties were always performed without interposition of cartilage between the tympanic membrane or the tympanic membrane graft and the disk-shaped portion of the implant, and extrusions were never observed. Long-lasting inflammatory processes appeared to destroy implants the same way they destroy ossicles. Transient inflammatory periods (such as episodes of purulent otitis media, which occurred soon after the prostheses were implanted) did…

Otitis media with effusion in children: Cross-frequency correlation in pure tone audiometry.

2019

Different guidelines are adopted in clinics and countries to assess pure tone hearing sensitivity in children with otitis media with effusion (OME). Some guidelines specify a broad range of audiometric frequencies that must be tested and from which average thresholds determined, while others leave test frequencies unspecified. For guidelines that suggest specific frequencies there are various pure tone frequencies and frequency ranges given. The present study investigated whether (1) a full range of audiometric frequencies is required to evaluate hearing loss caused by OME in children, or if neighboring frequencies provide essentially the same threshold information, and (2) if different com…

High-frequency conductive hearing loss as a diagnostic test for incomplete ossicular discontinuity in non-cholesteatomatous chronic suppurative otiti…

2017

Chronic suppurative otitis media, with or without cholesteatoma, may lead to erosion of the ossicles and discontinuity of the ossicular chain. In incomplete ossicular discontinuity (IOD), partial erosion of the ossicles occurs, but some sound transmission is noted throughout the ossicular chain. High-frequency conductive hearing loss (HfCHL) has been considered a hallmark of incomplete ossicular discontinuity. This study aims to evaluate the use of HfCHL as a preoperative predictor of IOD in patients with non-cholesteatomatous chronic suppurative otitis media. The HfCHL test was defined as the preoperative air-bone gap (ABG) at 4 kHz minus the average of the ABG at 0.25 and 0.5 kHz. The tes…

Risk factors for otitis media with effusion: Case–control study in Sicilian schoolchildren

2011

Objective To identify the prevalence and demographic, maternal and child risk factors for otitis media with effusion (OME) in Sicilian schoolchildren and analyse the results with reference to the review of the literature. Methods Associations of possible risk factors with prevalence of otitis media with effusion (OME) were studied in a cohort of 2097 children, aged 5–14 years. In order to determine OME, otoscopy and tympanometry were performed at 3-monthly intervals beginning at term date. Sixteen epidemiologically relevant features were inventoried by means of standardized questionnaires and skin tests were performed. Univariate analysis was performed to examine the association between det…

The point prevalence of otitis media with eVusion among primary school children in Western Sicily

2009

The objective of this study is to identify the prevalence of otitis media with effusion (OME) in primary school children and to value the possible predisposing factors focusing on relationship between allergy and OME in Western Sicily. 2,097 children attending primary school were screened from September 2006 to June 2007 in Sciacca. Children underwent pneumatic otoscopy, skin tests, tympanogram and acoustic reflex tests. Audiogram was performed if the child had a type B or a type C tympanogram. The criteria for diagnosis of OME were: documented persistent middle ear effusion by otoscopic examination for a minimum of 3 months, presence of B or C tympanogram, absence of ipsilateral acoustic r…

Otitis media with effusion with or without atopy: audiological findings on primary schoolchildren

2011

Objective: The objective of the study was to evaluate the role of atopy in otitis media with effusion (OME) in children attending primary school, focusing on the audiometric and tympanometric measurements among atopic and nonatopic subjects suffering from OME. Materials and Methods: Three hundred ten children (5-6 years old) were screened in Western Sicily by skin tests and divided into atopics (G1) and nonatopics (G2). The samples were evaluated for OME by pneumatic otoscopy, tympanogram, and acoustic reflex tests. The parameters considered were as follows: documented persistent middle ear effusion by otoscopic examination for a minimum of 3 months, presence of B or C tympanogram, absence …

The role of atopy in otitis media with effusion among primary school children: audiological investigation

2010

The objective of this study was to evaluate the role of atopy in otitis media with effusion (OME) in children attending primary school in western Sicily focusing on the audiological characteristics among atopic and non-atopic subjects suffering from OME. A total of 310 children (5-6 years old) were screened by skin tests and divided into atopics (G1) and non-atopics (G2). The samples were evaluated for OME by pneumatic otoscopy, tympanogram and acoustic reflex tests. The parameters considered were: documented persistent middle ear effusion by otoscopic examination for a minimum of 3 months; presence of B or C tympanogram; absence of ipsilateral acoustic reflex and a conductive hearing loss …
