“Proportional Condylectomy” for Vertical Condylar Hyperplasia Without Intermaxillary Elastics: Clinical Results and Patient Satisfaction

Abstract

Objectives: 

First, to investigate the clinical outcome of ‘proportional condylectomy’ for patients with active unilateral condylar hyperplasia without complementary treatment by intermaxillary elastics and, second, to examine their level of satisfaction regarding function and esthetics.

Study Design: 

A retrospective observational descriptive study was conducted. All patients included in the study suffered from active unilateral condylar hyperplasia with a vertical component. The length of the condylar-ramus unit was measured on both sides by an multidetector computed tomography scan. The difference was calculated and resected from the hyperplastic condyle during the operation. Facial, occlusal, and skeletal changes were evaluated using photographic and radiologic records, and a satisfaction questionnaire regarding function and esthetics was completed. P<0.05 was considered significant.

Results: 

Fifteen patients were included in the study. The mean participants’ age was 27.93±13.06 years, and the mean follow-up duration was 12.40±6.55 months. The mean chin deviation improved by 58.47% (P=0.001). Mean lip commissure plane tilt was improved by 61.31% (P=0.001). Six months postoperatively, all patients exhibited centered dental midlines (P=0.001). Occlusal plane tilt was significantly improved by 70.02% (P=0.001), and high patient satisfaction was recorded. Twenty-six percent (4/15) of patients did not require the complementary orthodontic treatment, and none of them required complementary orthognathic surgery.

Conclusions: 

‘Proportional condylectomy’ for patients with active unilateral vertical condylar hyperplasia without complementary treatment by intermaxillary elastics is a predictable procedure in terms of function and esthetics.
