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

Comparative Evaluation of Condylar Volume Between Patients With Unilateral Condylar Hyperplasia and Class III Dentofacial Deformity

“…1,2,6 It appears as a self-limiting, deforming, pathological condition causing alterations in facial bone and soft tissues, as well as stomatognathic functional problems. [1][2][3][4][5] The dentoalveolar and skeletal structures compensations happening in the presence of mandibular lateral deviation-as in the case of hemimandibular elongation UCH-include: canting of the maxillary plane and the subsequent canting of the occlusal plane by dentoalveolar supraeruption on the affected side, molar and canine ipsilateral class III dental relationships, midline deviation to the contralateral side, and cross bite or edge to edge bite on the unaffected side, with greater negative torque of the lower crowns on that side. 7 According to Olate et al, 8 condylar hyperplasia is the main cause of postnatal facial asymmetries.…”

“…1,2,6 Aparece como una condición patológica autolimitante y deformante, que ocasiona alteraciones en tejidos óseos y blandos faciales, así como problemas funcionales estomatognáticos. [1][2][3][4][5] Dentro de las compensaciones de las estructuras dentoalveolares y esqueléticas que ocurren cuando se presenta una desviación lateral mandibular, como en el caso de la HCU del tipo elongación hemimandibular, se encuentran: canteamiento del plano maxilar y subsecuente canteamiento del plano oclusal por supraerupción dentoalveolar en el lado afectado, relaciones dentales clase III molar y canina ipsilateral, desviación de la línea media hacia el lado contralateral y mordida cruzada o borde a borde en el lado no afectado, con mayor torque negativo de las coronas inferiores en ese lado. 7 Según Olate et al, 8 la hiperplasia condilar es la principal causa de asimetrías faciales posnatales.…”

The need for secondary orthognathic surgery after high condylectomy in patients with active unilateral condylar hyperplasia

“…Fariña et al prefer a proportional condylectomy over a HC. In their study, the need for secondary OS was reduced by 75.0%, from 90.9% in the HC group to 15.8% in the proportional condylectomy group 28 . In the present study, secondary OS was only needed in half of the patients after a HC.…”

“…The HC is performed routinely by some authors, while others avoid it due to possible functional problems afterwards 25 . The HC allows early intervention with minimal patient morbidity and may prevent supplementary surgery [26][27][28][29][30] . It provided a surprising simplification of the treatment in four (16%) of the present study patients, who were scheduled for supplementary OS in their initial treatment plan.…”

Unilateral condylar hyperplasia recurrence after orthognathic surgery: a case report

“…According to Fariña et al, the Authors believe that proportional condylectomy can be used as the sole surgical treatment in cases of UCH, avoiding the need for secondary orthognathic surgery [11].…”
