Ear and hearing problems in relation to karyotype in children with Turner syndrome
چکیده انگلیسی

The aim of the study was to report otologic and audiologic characteristics in a group of children with Turner syndrome (TS) and correlate these findings to karyotype. Additionally, we give recommendations for the otologic care of these children. Sixty children (age 1.7–21.2 years) were included in this retrospective study. Medical history and karyotypes were recorded and otologic and audiologic evaluation was performed. A history of recurrent otitis media was reported in 41/60 (68%) children and 3/60 (5%) had suffered from cholesteatoma. Audiometric data in 56 children revealed that normal hearing was only present in 33/112 (29%) ears. All other ears 79/112 (71%) were classified in five different audiometric categories for hearing loss. Hearing thresholds in general appeared to be about 10–11 dB worse in children with a monosomy 45,X or isochromosome (both have a total deletion of the short (p) arm of the X-chromosome) compared to those having a mosaicism or structural anomaly (partial deletion, or total deletion in only a few cells). Our findings support the hypothesis that hearing can be affected by loss of the p-arm of the X-chromosome. It is for the first time that a relation between hearing problems and karyotype is statistically confirmed in a large group of children with TS.


► Otologic disease is an important characteristic in children with Turner syndrome.
► Careful follow up during childhood is necessary to detect early ear and hearing problems.
► There are statistically significant differences in hearing thresholds among the different karyotypes, being worse in children with a monosomy or isochromosome as compared to those having a mosaicism or structural anomaly.
