Objectives:
In bilateral cleft lip/palate patients, sometimes the premaxilla is severely protruded and twisted. In such situations premaxillary osteotomy is beneficial. In this article a new technique for fixation of premaxilla after osteotomy is presented.
Methods:
The lip-split approach and premaxillary osteotomy and ostectomy from bony nasal septum were carried out. Fixation of osteotomized premaxilla was achieved with low profile miniplate or microplate. Bone grafting of that side was performed during the same session.
Results:
This procedure was performed in three patients, with good labial repair after the lip split. The bone graft was successful in all the three cases and there were no complication for premaxillary osteotomy in this series.
Conclusion:
In protruding premaxilla, osteotomy and fixation of premaxilla with miniplate to the vomer bone during alveolar bone grafting through a lip-split approach yielded satisfactory results in patients requiring secondary functional cheilorhinoplasty.
