ABSTRACT
The objective of this study is to investigate hearing losses in thalassaemic patients. This study was conducted on 34 thalassemic patients of which 27 of them had thalassaemia major and the remaining 7 had thalassaemia intermedia. Six (11.11%) of the 54 ears with thalassaemia major were found to have normal hearing. Thirty-two ears (59.26%) had conductive hearing loss, 8 ears (14.81%) had mixed type of hearing loss. Moreover, in this group, there was no ear which had pure sensorineural hearing loss. Of the majority of patients having thalassaemia major and thalassaemia intermedia, an air bone gap was found even though there was no negative pressure in the middle ear. In these patients a high degree of static compliance and normal shaped, stiff amplitude, normal pressure tympanograms were observed. Moreover, in most of these patients acoustic reflexes were not obtained. These findings are rather interesting since they show the pathological changes which may cause stiffness in the middle ear sound transmission system.
