GOALS: Evaluation of the audiological outcome and subjective satisfaction of BAHA Cordelle II in the treatment of patients with severe to profound bilateral mixed hearing loss.
MATERIAL AND METHOD: Retrospective study of 12 patients suffering a severe to profound bilateral sensorineural hearing loss, using pure tone audiometry (PTA), speech audiometry and subjective evaluation before and after the implantation of a BAHA Cordelle II (Cochlear(®)).
RESULTS: The average gain in conversational frequencies (0.5 to 4kHz) with BAHA in free field was 43, 51, 47 and 44dB, respectively. We observed a GAP over closure in 10 of the 12 patients. Speech audiometry improved from 85% at 83dB of maximum discrimination to 96% at 62dB. The subjective evaluation questionnaires showed great satisfaction with a slight decrease in noisy or windy environments. The great majority of our patients used the BAHA device throughout the entire day.
CONCLUSIONS: The BAHA Cordelle II (Cochlear(®)) is a good option in the treatment of severe to profound bilateral mixed hearing loss. Its best advantages are a low risk of labyrinthization, high result predictability, easy and step-by-step surgery, no need for general anaesthesia, and the GAP over closure in all frequencies. Active middle ear devices represent another alternative, but specific indications have not been defined yet because of low universal experience. When the intelligibility of the patient is poor, cochlear implantation should be considered.
