Background: Few reports have described the ophthalmic complications that occur after maxillary orthognathic\nsurgery. Since cases of decreased reflex tearing after maxillary orthognathic surgery are extremely rare, we describe\n2 cases of loss of reflex tearing after maxillary orthognathic surgery.\nCase presentation: Two Asian women, an 18-year-old and a 32-year-old, suffered from unilateral dryness and\nirritation caused by maxillary orthognathic surgery. In both patients, Schirmer test (II) showed reduced reflex tearing\nin 1 eye. Computed tomography showed that the pterygoid plate had been fractured in both patients.\nConclusions: The pterygopalatine ganglion and its associated fibers in the pterygopalatine fossa may be injured\nduring Le Fort osteotomy.
