Hyperplasie des Processus coronoideus: Diagnose und Therapie

Abstract

In comparison to the somewhat disappointing results of previously published studies with regard to mouth opening and mandibular mobility, our treatment concept seems to offer the possibility for improvement. Our study emphasizes the significance of three-dimensional CT techniques for diagnosis and surgical planning, the superiority of coronoidectomy over coronoidotomy, and the importance of dynamic physiotherapy to prevent postoperative scar formation.

Elongated coronoid process: CT-based quantitative analysis of the coronoid process and review of literature

“…The prevalence of asymptomatic coronoid hyperplasia is described as occurring in 0.5% of all cases in the literature 23 . Hyperplasia of the coronoid may occur due to an old trauma or due to functional alteration 24,27,37,47,57 . Based on animal experiments, SARNAT and ENGEL assumed hyperactivity of the temporal muscle 45 .…”

Behandlungsstrategien bei oromandibulärer Dystonie

“…Coronoidotomie und Coronoidektomie sind zwei typische chirurgische Eingriffe zur Behandlung von Trismus wie Hyperplasie des Processus coronoideus, Kiefergelenksankylose, quadratische Unterkieferform und Kaumuskel-Aponeurosen-Hyperplasie [77][78][79][80][81][82][83]. Während der Coronoidektomie wird der Processus coronoideus vollständig reseziert [79,82,83]. Im Gegensatz dazu wird während der Coronoidotomie der Processus coronoideus an seiner Basis geschnitten und an Ort und Stelle belassen (▶Abb.…”
