Purpose: The aim of this study was to determine the relationship of HLA typ
ing in patients with otosclerosis.
Materials and Methods: We used a prospective study in which HLA typing of 1
00 surgically confirmed otosclerosis patients were compared with age and se
x matched normal individuals.
Results: HLA-AB, HLA-AS, HLA-A11, and HLA-B13 were found to be significantl
y higher (P <.05, .01, and .01, respectively). HLA-A9 and HLA-A11 were foun
d to be higher (P <.01) in patients with a positive family history, indicat
ing genetic heterogenicity.
Conclusions: Higher values of HLA-A9, HLA-11, and HLA-B13 in patients with
otosclerosis compared with normal individuals strongly suggests a genetic,
HLA-related component. (Am J Otolaryngol 1999;20:102-105. Copyright (C) 199
