The aim of this study was to evaluate and discuss the long-term outcomes of patients with condylar osteochondroma managed through 3 different surgical techniques. Seven patients with condylar osteochondroma treated in the author's department from May 2012 to January 2019 were included in this retrospective study. Clinical evaluations (visual analogue scale for TMJ pain, jaw function, symmetry, and quality of life), maximum interincisal opening (MIO) and radiological findings were collected pre- and postoperatively. Other parameters assessed included tumour size and location; complications and follow-up. Radical condylectomy with immediate total joint alloplastic reconstruction was performed in 4 patients, local excision in 2 patients and low condylectomy with concomitant orthognathic surgery in 1 patient. During an average follow-up period of 40,8 months no clinical or radiographic signs of recurrence were found. Average MIO increased from 25,5mm to 39,5mm at the longest follow up, and all clinical evaluations were greatly improved. In conclusion, the described surgical techniques appear valuable in the treatment of condylar osteochondroma. Local excision is indicated in tumor involving less than half the surface of the condylar head; radical condylectomy with immediate alloplastic total joint reconstruction is indicated in gigantic lesion compromising the anatomical components and function of the joint. Orthognathic surgery procedures should be combined with tumor resection when correction of associated dentofacial deformities is indicated.

Abstract
The aim of this study was to evaluate and discuss the long-term outcomes of patients with condylar osteochondroma managed through 3 different surgical techniques. Seven patients with condylar osteochondroma treated in the author's department from May 2012 to January 2019 were included in this retrospective study. Clinical evaluations (visual analogue scale for TMJ pain, jaw function, symmetry, and quality of life), maximum interincisal opening (MIO) and radiological findings were collected pre- and postoperatively. Other parameters assessed included tumour size and location; complications and follow-up. Radical condylectomy with immediate total joint alloplastic reconstruction was performed in 4 patients, local excision in 2 patients and low condylectomy with concomitant orthognathic surgery in 1 patient. During an average follow-up period of 40,8 months no clinical or radiographic signs of recurrence were found. Average MIO increased from 25,5mm to 39,5mm at the longest follow up, and all clinical evaluations were greatly improved. In conclusion, the described surgical techniques appear valuable in the treatment of condylar osteochondroma. Local excision is indicated in tumor involving less than half the surface of the condylar head; radical condylectomy with immediate alloplastic total joint reconstruction is indicated in gigantic lesion compromising the anatomical components and function of the joint. Orthognathic surgery procedures should be combined with tumor resection when correction of associated dentofacial deformities is indicated.
