“…Some authors reported proportional condylectomy to be an effective sole treatment for active CH, achieving both arrest of the hyperplastic growth and gradual symmetry of the face. [15][16][17][18][19][20][21][22][23][24] In a recently published article by Abboud et al 25,26 , the effectivity of proportional condylectomy as a single treatment to achieve symmetry in CH type 1 (unilateral hemimandibular elongation) was examined. The results clearly showed that while some facial and gnathic features improved, others actually worsened.…”

The purpose of the present study was to evaluate the 3-dimensional orofacial changes occurring after proportional condylectomy in patients with unilateral condylar hyperplasia type 2 (hemimandibular hyperplasia). Eight patients underwent proportional condylectomy that was not followed by orthognathic surgery or orthodontic treatment for at least 1 year. The precondylectomy and postcondylectomy photographs and radiographs were analyzed cephalometrically and compared. The average length of the condylar segment removed was 13 mm and this resulted in almost equal heights of the ramus-condyle units of both sides. Evaluations in the vertical plane improved after surgery; however, when the preoperative asymmetry was significant, the residual asymmetry continued to be notable after condylectomy. Transverse plane evaluations improved after condylectomy, and chin position was satisfactorily centralized in all patients. In the horizontal plane, mandibular setback occurred, and this was considered favorable when the preoperative skeletal profile was class III, whereas the opposite was when the patient was class I before surgery. The occlusion improved gradually over the postoperative months by the intrusion on the affected side and extrusion on the unaffected side into a bilaterally balanced posterior contacts with residual anterior open bite. In conclusion, condylar hyperplasia type 2 patients with mild asymmetry and low esthetic demands can benefit from proportional condylectomy as the sole treatment to both stop the hyperplastic condylar growth and improve the asymmetry to some extent. Surgeons should be able to predict the change that is expected to occur after proportional condylectomy and discuss this with the patient before surgery.

“…Da die Patientin bereits vor Therapiebeginn zwei harmonisch ausgeformte Zahnbögen aufwies, stellt sich die Frage ob in diesem Fall die hohe Kondylektomie als Therapie ausgereicht hätte. In der Literatur werden Fälle beschrieben, welche ein sehr gutes funktionelles und ästhetisches Ergebnis mit alleiniger Korrektur des vertikalen Überschusses erzielten 9 . Die Autoren vertreten jedoch die Meinung, dass die Entscheidung, ob eine Sekundärkorrektur im Sinne einer Umstellungsosteotomie durchgeführt wird, immer von Fall zu Fall entschieden werden sollte, da Patient*innen mit mandibulärer Asymmetrie neben der vertikalen Anomalie häufig auch transversale (Kreuzbiss, bukkale Nonokklusion) und sagittale (Angle Kl.…”

ZusammenfassungMandibuläre Asymmetrien die mit persistierendem Unterkieferwachstum assoziiert sind, manifestieren sich häufig im jungen Erwachsenenalter. Konservativen Therapieansätzen sind diese Dysgnathien nicht mehr zugänglich. Therapie der Wahl stellt ein kombiniert kieferorthopädisch-kieferchirurgisches Konzept dar. Der nachfolgend dokumentierte Fall soll ein mögliches Therapiekonzept am Beispiel einer jungen Patientin mir hemimandibulärer Hyperplasie veranschaulichen.
