Loss of reflex tearing after maxillary orthognathic surgery: a report of two cases
نویسندگان
چکیده
BACKGROUND Few reports have described the ophthalmic complications that occur after maxillary orthognathic surgery. Since cases of decreased reflex tearing after maxillary orthognathic surgery are extremely rare, we describe 2 cases of loss of reflex tearing after maxillary orthognathic surgery. CASE PRESENTATION Two Asian women, an 18-year-old and a 32-year-old, suffered from unilateral dryness and irritation caused by maxillary orthognathic surgery. In both patients, Schirmer test (II) showed reduced reflex tearing in 1 eye. Computed tomography showed that the pterygoid plate had been fractured in both patients. CONCLUSIONS The pterygopalatine ganglion and its associated fibers in the pterygopalatine fossa may be injured during Le Fort osteotomy.

Orthognathic surgery to advance the maxilla in these patients is not very efficient; therefore, orthopedic interventions during an appropriate age seems to be essential. Case Report: In this article, two cleft lip and pa...
