Objective: To describe the intraoperative findings and outcomes of stapedectomy surgery in Teunissen-Cremers syndrome.
Patients: A family of three patients with bilateral conductive hearing loss because of Teunissen-Cremers syndrome.
Intervention: Six exploratory tympanotomies and stapedectomies, including one revision operation.
Main outcome measures: Intraoperative findings and postoperative hearing results.
Results: There was an increased distance between the incus and the vestibule, a thicker long process of the incus, and slight variation in the relative position of the ossicles in all patients. Surgery resulted in closure of the air-bone gap to less than 10 dB in all five operated ears.
Conclusion: We describe anatomic abnormalities of the ossicular chain in Teunissen-Cremers syndrome. Prosthesis availability should include prostheses that can adapt to these potential anatomic abnormalities. Stapedectomy resulted in good long-term hearing outcomes in this series.
