The Role of Adenoidal Obstruction in the Pathogenesis of Otitis Media with Effusion in Nigerian Children

Background: Although adenoidectomy is generally applied in the treatment of otitis media with effusion (OME); there is still much debate about the role of adenoid in the pathogenesis of OME. The purpose of this study is to determine the incidence of OME in children with obstructive adenoid disease in comparison with normal control; and the degree of nasopharyngeal obstruction by adenoid as it relates to the development ofOMEin Nigerian children. Method: Controlled; prospective clinical study was carried out. Diagnosis of OME was made with finding of type B tympanogram on tympanometry evaluation. The incidence of OME among adenoidal patients was compared with its incidence in normal control. The degree of nasopharyngeal obstruction among the adenoidal subjects was evaluated with an adenoidal-nasopharyngeal ratio parameter obtained from soft tissue radiograph of nasopharynx; and was related to the results of tympanometric evaluation of the adenoidal subjects. Results: The incidence of OME was significantly higher in the adenoidal children than the normal control (p 0.001). The risk ofOMEwas more than 7 times as more among adenoidal group than among the non-adenoidal control. Gross nasopharyngeal obstruction was significantly associated with type B tympanogram (p

Otoscopy Compared with Tympanometry: An Evaluation of the Accuracy of Simple Otoscopy

Background: Although otoscopy has been shown to compare favourably with results of tympanometry; the actual diagnostic value of otoscopy for otitis media with effusion (OME) has not been evaluated in Nigeria. The study was aimed at evaluating the sensitivity; specificity and predictive value of otoscopy in the diagnosis of OME as compared with tympanometry. Method: It was a prospective hospital-based; descriptive cross-sectional study in which the results of simple otoscopy were compared with results of the tympanometry of 82 ears of children aged between 6 months and 12 years; who presented to the Otolaryngology clinics of the UNTH Enugu with symptoms of obstructive adenoid enlargement. Results: Simple otoscopy produced 84.4agreement with tympanometry in detecting OME. The agreement was better in older children than the younger ones (P
