  • Abstract
  • Look Inside

 The authors tested otoscopical and audiologi cal findings of 32 patients who were operated on by the total resection of maxilla because of its malignant tumor.

 Homolateral hearing loss was found in 72 per cent of cases. The origins of their hearing impairment were considered due to the serous otitis media as the result of tubal dysfunction and also due to the supprative otitis media.

 In combination with the existing presbycusis, this kind of conductive deafness appeared as the mixed type of hearing loss. The threshold of the impaired hearing was not always fixed. It might be fluctuated according to the conditions of nasopharyngeal space.
