초록

Purpose: Fractures of the mandibular condyle accounts for 15% to 30% of all the mandibular fractures
and lots of complications are reported. Among these complications, condylar resorption is the most important
one to be taken into account. The purpose of this study is evaluating condylar resorption pattern in
relation to extracorporeal fixation technique.
Patients & methods: Thirty four patients with 42 mandibular condylar fractures were retrospectively
examined with an average follow-up of 18.5 months (6-66 months). Male/female ratio is 27 males (7 bilateral
cases) and 7 females (1 bilateral case). Applicated surgical techniques were extracorporeal fixation via
submandibular approach and extracorporeal fixation via intraoral approach. We compared radiographic
views of post-operative periods with that of most long term follow up in 34 operated sites respectively.
Result: There were 2 generalized condylar resorption sites and 3 partial resorption sites with clinical
implications. Others (29 joints) showed good healing or satisfactory adaptive state of temporomandibular
joints clinically. Radiologically, signs of partial condylar resorption and/or osteoarthrosis were diagnosed in
11 patients. But, 8 out of the 11 patients didn’t show significant clinical symptoms, which means successful
adaptive remodeling of the surgically located condyalr head.
Conclusion: From the above results, intentional ramal osteotomy, temporory detachment of the fractured
condyle and extracorporeal fixation technique seems to be effective and useful in those cases of
condylar fractures in which reduction of the dislocated condyle is very difficult or virtually impossible.
