Congenital External Ear Deformity and Their Hearing Rehabilitation With Bone Anchored Hearing Aid: A Retrospective Analysis
Author: Hetal Marfatia, Ratna Priya
Objectives: Microtia-anotia is a spectrum of congenital anomalies of the auricle ranging from mild structural abnormalities to complete absence of the ear. Early amplification, auditory training, and speech therapy can improve speech and language development.
Materials and Methods: Case Records of 30 patients with congenital external deformity during the time period from January 2010 to June 2013 were reviewed for the grade of microtia, the degree and type of hearing loss and hearing rehabilitation.
Results: Out of 30 patients, 22 patients were given hearing rehabilitation either in the form of bone anchored hearing aid – soft -band or Baha implant. 9 patients underwent Baha surgery. Mean post rehabilitation improvement was 23.4 dB. Closure of the air- bone gap was observed in one patient.
Conclusion: Baha is an excellent option for hearing rehabilitation in patients with congenital conductive hearing loss.
