Abstract

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.

期刊介绍： The purpose of the International Journal of Pediatric Otorhinolaryngology is to concentrate and disseminate information concerning prevention, cure and care of otorhinolaryngological disorders in infants and children due to developmental, degenerative, infectious, neoplastic, traumatic, social, psychiatric and economic causes. The Journal provides a medium for clinical and basic contributions in all of the areas of pediatric otorhinolaryngology. This includes medical and surgical otology, bronchoesophagology, laryngology, rhinology, diseases of the head and neck, and disorders of communication, including voice, speech and language disorders.
