Augmentation mentoplasty with osteocartilaginous nasal graft

Objective

Augmentation mentoplasty is a common procedure, applied especially in conjunction with rhinoplasty. Although various materials have been used, autogenous nasal hump tissue has not been studied in a big series of patients. The main objective of this study was to evaluate the use of autogenous nasal hump in chin augmentation.

Study Design

Case series with chart review.

Setting

University hospital.

Subjects and Methods

The osteocartilaginous mentoplasty procedure was performed in 124 patients along with rhinoplasty in a series of 218 patients who had undergone combined rhinoplasty and mentoplasty with various techniques. The median follow-up was 58 months (range, 12-120 months) over a 10-year period. The procedure commenced under general anesthesia for all patients with large humps and poor chin projection. During the rhinoplasty procedure, the osteocartilaginous nasal hump was removed, tailored to achieve an anatomic mental form, and inserted into the mental pocket through a submental or an intraoral incision.

Results

Infection was detected in five patients, two of whom required graft removal. All other patients recovered normally along an almost painless process, without displacements or any other complaints.

Conclusion

Nasal hump in reduction rhinoplasty is a useful alternative for augmentation mentoplasty on patients with large humps and poor chin projection. It also avoids all the disadvantages of alloplastic materials and eases integration compared with other alternatives in selected cases.
