Patients with Treacher Collins syndrome often exhibit conductive hearing loss due to middle ear malformation. We report a case of this syndrome in a 41-year-old woman with bilateral conductive hearing loss, in whom adjustment of hearing devices was complicated. After assessing HRCT images using Jahrsdoerfer's grading scale, we performed tympanoplasty type III-c on the left side followed by type III-i on the right side. The patient had an excellent outcome; ultimately hearing devices were not required. Preoperatively, patients with congenital anomalies of the middle ear can benefit greatly from prediction of postoperative prognosis; use of Jahrsdoerfer's grading system to assess HRCT images can help to ensure safe and effective surgical care.
Key words : Treacher Collins syndrome, conductive hearing loss, tympanoplasty, Jahrsdoerfer's grading system
