Objective: Determine the utility of radio guided surgery for the eradication of condylar hyperplasia.

Methods: A five-year prospective Cohort study was designed. A preliminary report with 6 cases is presented. Patients included in the study were diagnosed with unilateral condylar hyperplasia. Before surgery a CT-bone scan fusion study was performed in every patient in order to establish location and amount of bone to be resected. Radio guided surgery was performed and specimens were analyzed for histopathological diagnosis. Clinical and radiographic follow was performed. Postoperatory bone scan was taken two years after surgery. Cases that have not completed 2 years of postop have been followed clinically.

Results: Since the actual sample includes only six patients, we present conclusions of this preliminary report as descriptive data. The number of patients up to date is six. Three female and three male patients. Age range was between 15 and 28 years. CT-bone scan fusion reported location of increase of activity of the condyle and every one was registered. Activity was increased in the upper third in three patients, in the middle third in two patients and in the lower third in one patient. A good correlation between surgical specimen and histopathological analysis. All patients have been followed for 1–24 months. Relapse has not been found in any of the patients reported up to 24 months.

Conflict of interest: None declared.
