The morphology of central tympanic membrane perforations.
Artigo em Inglês | IMSEAR | ID: sea-46891
ABSTRACT
The objective of this study was to assess the extent of conductive hearing loss in relation to different sizes and sites of simple central tympanic membrane perforations. Total 100 cases attending ENT OPD, BPKIHS during period of April 2003 to Mar 2004 without any discrimination of sex, race and religion were taken for the cross sectional prospective study. Dry, clean central tympanic membrane perforations due to various causes like chronic suppurative otitis media-tubotympanic, post acute suppurative otitis media residual perforations or simple traumatic perforations with conductive hearing loss and without preexisting hearing loss were clinicoaudiologically evaluated and analyzed. Hearing loss was found to be directly proportional to the size of perforation irrespective of their cause, which was statistically significant. Hearing loss in the study was found to range from negligible to 53dB. Overall, perforations involving posterioinferior quadrant were found to have maximum hearing loss.
