Mastoid bone autograft for dorsal nasal augmentation

Introduction: Several grafts and/or implants have been used for dorsal augmentation. In some cases, especially the traumatic, non-caucasian, and multi-operated ones, the amount of augmentation is higher than the usually available from septal and auricular conchal autografts.

Objective: To evaluate the safety and efficacy of mastoid bone autograft for dorsal nasal augmentation in rhinoplasty.

Methods: A prospective study of 20 consecutive patients who underwent dorsal nasal augmentation with mastoid bone, during a 4-year period. Main outcome measures were clinically noted complications and patient/surgeon satisfaction.

Results: The grafts ranged from 5 to 12 mm in thickness. Follow-up ranged from 6 months to 4 years. Seventeen (85.0%) patients presented satisfactory results for both the surgeon and the patient. One patient showed a slight excessive augmentation noted only by the surgeon. One patient presented a lack of augmentation that needed a revision surgery. One patient needed a revision surgery due to graft dislocation in the first post-operative month. No case presented infection nor graft absorption.

Conclusions: Mastoid bone presented as an effective autograft material for dorsal nasal augmentation in rhinoplasty. The complication rate is low. Long-term follow-up showed that no absorption occurs.

Conflict of interest: None declared.
