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…

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…

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 …

Proliferating macrophages, dendritic cells, natural killer cells, T and B lymphocytes in the middle ear and Eustachian tube mucosa during experimenta…

2001

SummaryAlthough many studies focus on the increase of immunocompetent cells within the middle ear mucosa during acute otitis media it is poorly understood how this increase is mediated. The differentiation between two possible causes, i.e. immigration and local proliferation, would help to better understand the pathophysiology of this disease. Therefore, the number of proliferating macrophages, dendritic cells, natural killer cells and T and B lymphocytes was studied during acute otitis media in the rat middle ear mucosa (ME mucosa) and Eustachian tube mucosa (ET mucosa) by labelling proliferating leucocytes with the DNA precursor bromodeoxyuridine (BrdU). By removing the middle ear and Eus…

The prognostic value of subjective nasal symptoms and SNOT-22 score in middle ear surgery

2022

Background: The relationship between nasal functions and middle ear surgery is still under debate. Nasal obstruction is considered as a negative prognostic factor in middle ear surgery. This is based on the theory that it may cause Eustachian tube dysfunction (ETD) by leading to reduced ventilation of the middle ear, as found in several patients with nasal septal deviation, chronic rhinitis and nasal polyps. Objectives: To assess how the subjective feeling of nasal function, evaluated by a preoperative questionnaire, may be predictive of surgical outcome and/or risk of failure in middle ear surgery. Methods: We prospectively evaluated data of patients undergoing middle ear surgery for chron…

Audiological Investigation of Otitis Media in Children with Atopy

2011

Otitis media (OM) describes an inflammatory process within the middle ear space that is generally associated with accumulation of fluid and that may lead to hearing loss, learning difficulties, and delays in language development. The pathogenesis of OM is multifactorial, involving the adaptive and native immune system, eustachian tube dysfunction, viral and bacterial load, and genetic and environmental factors. The involvement of IgE-mediated allergic reactions in the pathogenesis of OM has been suggested by clinical observations of a high prevalence of OM among patients with allergies. Evidence from studies involving tympanometric measurements, audiometric measurements, and otoscopic exami…
