Summary
The retrosigmoid approach for BONEBRIDGE implantation is safe and effective for aural atresia patients undergoing auricular reconstruction. This combined technique improves hearing and aesthetics without increasing surgical risks.
Area of Science:
- Otolaryngology
- Neurosurgery
- Plastic Surgery
Background:
- The retrosigmoid (RS) approach is not commonly used for BONEBRIDGE implantation.
- Simultaneous auricular reconstruction and BONEBRIDGE implantation present unique surgical challenges.
Purpose of the Study:
- To evaluate the efficacy and safety of combining auricular reconstruction with BONEBRIDGE implantation using the retrosigmoid approach.
- To assess the impact of this integrated approach on hearing outcomes and aesthetic results in patients with aural atresia.
Main Methods:
- Retrospective analysis of 15 children (28 ears) who underwent auricular reconstruction with an expanded postauricular flap and retrosigmoid BONEBRIDGE implantation.
- Data collected on healing, bone conduction, speech فهم improvement, and aesthetic outcomes.
- Follow-up duration ranged from 21 to 35 months.
Main Results:
- All patients achieved successful healing with no bone conduction shift.
- Significant improvements in Speech Frequency Threshold (SFT) by an average of 27.1 dB HL (p < .001).
- Marked improvements in aided versus unaided speech recognition in both quiet and noisy environments (p < .001).
- Stable hearing results and satisfactory aesthetic outcomes observed post-surgery.
Conclusions:
- The retrosigmoid approach is suitable for BONEBRIDGE implantation in patients undergoing auricular reconstruction, as it avoids flap interference.
- This integrated surgical technique offers a safe, convenient, and effective option for simultaneous auricular reconstruction and BONEBRIDGE implantation.
- The approach does not increase surgical risks or significantly prolong anesthesia time, leading to positive clinical and aesthetic results.
