ObjectiveTo investigate the incidence and reasons for titanium fixation plate removal following orthognathic surgery, identify risk factors predisposing removal and to explore if discomfort was reduced postoperatively.MethodsMedical records of 404 consecutive patients were retrospectively reviewed. All patients received a questionnaire for follow-up. 323 patients answered the questionnaire thus set the sample group.ResultsFifteen percent of all the responding subjects had plates removed and 92% of these patients were relieved from discomfort after removal. Infection was the most common reason for plate removal (10%). Smoking (Hazard Ratio (HR) 2.74) and surgery performed in the mandible (HR 2.40) increased the need for plate removal. For each plate added in the mandible the risk for removal increased with (34%).ConclusionsSmoking, osteotomies and additional numbers of plates in the mandible, resulted in more plate removal. Most of the patients were relieved from discomfort after plate removal.
