title: [Rare complication after Le Fort I osteotomy].
abstract: Malfunctions of the eustachian tube after Le Fort I osteotomies are rare. A 22-year-old woman was treated by Le Fort I osteotomy for maxillary retrognathism. Postoperatively she developed recurrent tubal malfunction and middle ear effusions on the left side, with no improvement after adenotomy, tonsillectomy, and grommet insertion. In consecutive computed tomography and magnetic resonance imaging scans, a forward dislocation of the left pterygoid hamulus was demonstrated. In addition, damage to the tensor veli palatini muscle was evident. Both postoperative sequelae appear to be responsible for the unilateral tubal dysfunction.
