Correction of facial deformities in patients with mild bleeding disorders: a report of three cases.

A bleeding diathesis need not be a contra-indication to elective surgical correction of facial deformities. Preoperative haemostatic assessment and management of haemostasis during and after surgery is described. Two cases of mild von Willebrand's disease and one case of factor XI deficiency who successfully underwent orthognathic surgery for the correction of facial deformities are reported.
