OBJECTIVE: To investigate the effect of vibrant sound bridge implantation in microtia whose reconstructive external auditory canal occurred atresia.
METHOD: Three cases (2 males and 1 female) of microtia had underwent hearing reconstruction operation (Include the external ear canal reconstructive surgery and tympanoplasty). The age ranged from 15 to 18 years and the average age was 17 years. All the 3 cases suffered from conductive hearing loss with the air-bone gap ranging from 51.6 to 65.0 dB HL and the average value being 56. 3 dB HL. All the 3 cases underwent vibrant sound bridge implantation, including the floating mass transducer implanted in the head of stapes in 2 cases and in the niche of round window in 1 case.
RESULT: The postoperative hearing level improved from 21.6 to 52.5 dB HL with an average of 32.2 dB HL. There were no complications such as vertigo, tinnitus and facial paralysis.
CONCLUSION: Through vibrant sound bridge implantation, the hearing level of microtia whose reconstructive external auditory canal occurred atresia was improved effectively.
