Abstract

PURPOSE
Ameloblastomas are rare benign tumors of odontogenic origin, and compose about 1% of all oral and maxillomandibular cysts and tumors. Because this neoplasm has a high rate of local recurrence, segmental mandibulectomy with a 1~2cm safety margin and immediate microsurgical reconstruction is an accepted treatment modality. The authors experienced four mandibular reconstruction cases that underwent secondary dental implantation. Here, the authors describe these cases and their long-term results. METHODS: Four patients with ameloblastoma of the mandible underwent segmental mandibulectomy and reconstruction with a free fibula osseous flap from January 1999 to May 2005, followed by secondary dental implantation. Recurrence, bony union, implant osseointegration, and functional and aesthetic results were evaluated by radiologic imaging, by physical examination, and by using photographs.
RESULTS
All free flaps survived with no evidence of flap loss. To date, no recurrence has been noted clinically or radiologically. Imaging after mandibular reconstruction with a free fibular flap revealed satisfactory bony unions and mandibular contours. The patients achieved good aesthetic and functional results after the secondary implantation.
CONCLUSION
Mandibular reconstruction using a fibular osseous flap and secondary dental implantation can produce good functional and aesthetic results after segmental mandibulectomy for ameloblastoma.
