Abstract: Objective To evaluate the clinical applications of Contact Mini in patients with bilateral congenital microtia. Methods Contact Mini and bone anchoring hearing aids(BAHA)worn by 36 patients with bilateral congenital microtia were compared in terms of pure tone hearing sound field audiometry findings, before and after wearing.The patients were followed up to observe daily communication and the response to sound after wearing Contact Mini. Results Hearing improved by an average of 38.8 dB and 34.5 dB after Contact Mini and BAHA usage, respectively. Although there was no statistically significant difference between the two groups(P>0.05), the daily communication was significantly improved. Conclusions Contact Mini device can effectively improve audiometry with a satisfactory effect in bilateral congenital microtia patients.

Key words: Bilateral congenital microtia, Contact mini, Bone anchorinag hearing aids, Sound field audiometry
