Abstract:
A 33-year-old female patient developed an ipsilateral sixth nerve palsy and partial third nerve palsy following a Le Fort 1 osteotomy. Complete resolution occurred at 10 weeks. The likely mechanism of injury secondary to pterygo-maxillary dysjunction is highlighted, with description of the relevant anatomy. Previous cases of ocular motility complications following Le Fort 1 osteotomy are discussed. We recommend that significant care be taken in osteotome placement in the pterygo-maxillary fissure, particularly in those prone to unpredicted fractures such as older patients, or where the anatomy is congenitally abnormal or altered by previous surgery.
