Abstract(s)
A articulação Temporomandibular (ATM) é a principal ligação entre o crânio e a
mandíbula e é das articulações mais complexas e solicitadas funcionalmente no corpo
humano.
Esta articulação não é imune a alterações, quer estas sejam provocadas por mecanismos
intrínsecos ao sistema estomatognático, quer através de acidentes ou até mesmo de
cirurgias de correção dos maxilares - Cirurgia Ortognática. A alteração na ATM que
mais comummente ocorre após a cirurgia ortognática é a reabsorção condilar.
Esta revisão narrativa da literatura teve como objectivo aferir a real relação entre a
cirurgia ortognática e a reabsorção condilar, bem como, as características desta
patologia.
A literatura verifica uma relação entre a cirurgia ortognática e a reabsorção condilar,
associada mais frequentemente ao tipo de osteotomia e ao tipo de fixação pós-cirúrgica.
No entanto, mais estudos caso-controlo, como amostras de maior dimensão deverão ser
realizados para suportar estas evidências.
The temporomandibular joint (TMJ) is the main connection between the skull and the mandible and is the most complex and functionally requested joint in the human body. This joint is not immune to changes, whether these are caused by mechanisms intrinsic to the stomatognathic system, on through accidents or even surgery for correction of the jaws. The most common alteration in TMJ after orthognatic surgery is condylar resorption. This narrative review of the literature aimed to assess the relationship between orthognatic surgery and condylar resorption as well as the characteristics of this pathology. The literature shows a relationship between orthognathic surgery and condylar resorption, most frequently associated with the type of osteotomy and the type of postoperative fixation. However more case-control studies with larger sample sizes should be performed to support this evidence.
