Abstract |
Cranial nerve injury is a described complication of Le Fort I osteotomy technique. The authors present the case of a 45-year-old patient that underwent bimaxillary orthognathic surgery and suffered unfavorable skull base fractures, which resulted in cranial nerve injury of the II, III, IV, V, and VI nerves on the left side and of the V nerve on the right side, through different mechanisms. One of the mechanisms was cavernous sinus thrombosis, which was never described following Le Fort I technique in a non-cleft patient. The fracture pattern involved the foramen ovale and Meckel's cave, which was also never described after this technique. The resolution of the deficits at the final follow-up at 14 months was incomplete. Le Fort I osteotomy technique is considered a safe technique to correct dentofacial deformities, but serious complications can occur. Pterygomaxillary disjunction and down-fracture must be performed with the utmost care to avoid it.
