Low Condylectomy and Orthognathic Surgery to Treat Mandibular Condylar Osteochondroma: A Retrospective Review of 37 Cases

High condylectomy versus proportional condylectomy: is secondary orthognathic surgery necessary?

“…11,14 Recently Wolford et al 4 published an update of their condylar hyperplasia classification and placed the high condylectomy together with disc repositioning and orthognathic surgery as the preferred treatment for UCH cases and also for cases of bilateral condylar hyperplasia. In 2002, Wolford et al, 8 using the same technique, showed its efficacy and stability, presenting close to 5 years of follow-up for the patients who were operated on.…”

“…Saridin et al 15 presented 33 patients who underwent high 4 Fariña et al condylectomy surgery without disc replacement, although the need for orthognathic surgery in these patients was not addressed.…”

“…6,17 Thus, when the upper layers of the condyle show themselves to be compromised, a high condylectomy could contribute to limiting anomalous growth of the condylar head. 18 The low condylectomy has been used in cases of osteochondroma 4,19 and in active condylar hyperplasia 14 without complications, proving that a low condylectomy does not restrict the functionality of the articulation and allows posterior facial heights to be equalled (between the hyperplastic and the healthy sides). Thus, a condylectomy that is performed lower than the level traditionally considered to be a high condylectomy would not limit mandibular function or stability, allowing the 'proportional condylectomy' to establish a mandibular function without complications.…”

“…Studies involving radiological series, radiographic analysis, and studies of the face and dental models with a difference of at least 6 months between them have typically been used. 4 Studies performed using single photon emission computed tomography (SPECT) and positron emission tomography (PET) have also shown their diagnostic efficacy, although histological studies of the specimens obtained have not always proven a constant relationship between UCH and the results using SPECT. 5,6 To date, a good diagnostic approach to condylar hyperplasia is with anamnesis and clinical and SPECT confirmation.…”

“…However, Walford et al [14] stressed that the second decade is the most suitable for this condition (68%). It has a female predilection [4,9,11,14], which could indicate a hormonal correlation [14].…”
