To evaluate karyotype-specific ear and hearing problems in young-adult patients with Turner syndrome (TS) and assess the effects of previous treatment with oxandrolone (Ox).


Double-blind follow-up study.


University hospital.


Sixty-five TS patients (mean age, 24.3 yr) previously treated with growth hormone combined with placebo, Ox 0.03 mg/kg per day, or Ox 0.06 mg/kg per day from the age of 8 years and estrogen from the age of 12 years.


Ear examination was performed according to standard clinical practice. Air- and bone conduction thresholds were measured in decibel hearing level.


We compared patients with total monosomy of the short arm of the X chromosome (Xp), monosomy 45,X and isochromosome 46,X,i(Xq), with patients with a partial monosomy Xp, mosaicism or other structural X chromosomal anomalies. We assessed the effect of previous Ox treatment.


Sixty-six percent of the patients had a history of recurrent otitis media. We found hearing loss in 66% of the ears, including pure sensorineural hearing loss in 32%. Hearing thresholds in patients with a complete monosomy Xp were about 10 dB worse compared with those in patients with a partial monosomy Xp. Air- and bone conduction thresholds were not different between the placebo and Ox treatment groups.


Young-adult TS individuals frequently have structural ear pathology, and many suffer from hearing loss. This indicates that careful follow-up to detect ear and hearing problems is necessary, especially for those with a monosomy 45,X or isochromosome 46,X,i(Xq). Ox does not seem to have an effect on hearing.
