Abstract

Progenism (mandibular prognathism) is a cranial-maxillary-occlusal disorder involving the excessive growth of the mandible in relation to the maxilla. This defect affects not only the facial appearance – protrusion of the chin and lower lip, but also may lead to different types of functional disorders, including dysfunction of the temporomandibular joint. This paper presents a historical background of the orthognatic surgeries applied for prognathism correction and an overview of current operative techniques as well as postoperative complications reviews. Currently, bilateral sagittal split osteotomy (BSSO) stands as the most popular surgical method in correction of mandibular prognathism. Despite the fact that the BSSO method is becoming increasingly popular, some centres in Poland and all over the world still tend to perform external vertical ramus osteotomy (EVRO) and intraoral vertical ramus osteotomy (IVRO). In majority of performed mandibular osteotomies complications are related with sensory disturbances within the area of inferior alveolar nerve and more commonly concern patients undergoing bilateral sagittal split osteotomy.

Streszczenie

Progenia (przodożuchwie morfologiczne, prognatyzm żuchwy) jest wadą czaszkowo-szczękowo-zgryzową polegającą na nadmiernym wzroście doprzednim żuchwy w stosunku do szczęki. Wada ta wpływa negatywnie nie tylko na wygląd twarzy – wysunięcie bródki oraz dolnej wargi, lecz również może prowadzić do wystąpienia różnego rodzaju zaburzeń czynnościowych, w tym dysfunkcji stawów skroniowo-żuchwowych. W pracy przedstawiono rys historyczny dotyczący metod korekcji progenii oraz przegląd aktualnych technik zabiegowych z uwzględnieniem ich powikłań pooperacyjnych. Aktualnie najbardziej popularną metodą operacyjną jest obustronna strzałkowa osteotomia gałęzi żuchwy (bilateral sagittal split osteotomy – BSSO). Pomimo jej rozpowszechnienia nadal w niektórych ośrodkach zarówno w Polsce, jak i na świecie jest wykonywana operacja metodą obustronnej pionowej osteotomii gałęzi żuchwy z cięcia zewnątrzustnego (external vertical ramus osteotomy – EVRO) i wewnątrzustnego (intraoral vertical ramus osteotomy – I VRO). W większości przypadków osteotomii gałęzi żuchwy powikłania są związane z zaburzeniami czucia w obrębie nerwu zębodołowego dolnego i częściej dotyczą pacjentów poddawanych zabiegom obustronnej strzałkowej osteotomii gałęzi żuchwy.
