OBJECTIVE: To evaluate the effectiveness and safety of using the retrosigmoid sinus approach for BONEBRIDGE implantation in patients undergoing auricle reconstruction with tissue expansion flap.
METHODS: 44 patients who accepted BONEBRIDGE implantation through the retrosigmoid sinus approach were included. Audiological outcomes were measured before and after the BONEBRIDGE implantation. Long-term hearing and complications were also evaluated.
RESULTS: After surgery, there was no significant change in bone conduction hearing thresholds compared to pre-surgery levels. Sound field thresholds after being aided with BONEBRIDGE showed a significant decrease of 27.2 dB HL. Speech recognition scores of monosyllabic words, disyllabic words, and short sentences in quiet environments significantly increased to 72 %, 84 %, and 98 %, respectively. During the 8-51 months follow-up, audiological results remained stable, and all patients were satisfied with the aesthetics of auricle reconstruction.
CONCLUSION: Patients with bilateral microtia, undergoing auricle reconstruction with expanded postauricular flap, were chosen for the retrosigmoid sinus approach during BONEBRIDGE implantation and achieved safety, good hearing results as well as improved aesthetics.
