title: [Evaluation of auditory function in homozygous beta-thalassemia].
abstract: We examined the auditory function of 29 subjects affected by homozygous beta-thalassemia, managed with an high transfusion scheme and regularly treated with 40-60 mg/kg/day of desferrioxamine. A group of 29 healthy subjects is studied as control. We found conductive hearing defect in 8 thalassemics (6 bilateral) and sensory-neural hearing loss at high frequencies in 4. Thalassemic patients showed more auditory impairment than controls, an higher incidence of tonsillar hypertrophy, adenotonsillitis and submandibular lymph-node enlargement.
