Opis:
The aim of the study was to analyze the results of patients’ subjective self-assessment of surgical treatment of prognathism. Materials and methods. The study included 35 patients who underwent extraoral vertical ramus osteotomy. Each patient responded to 12 questions contained in the questionnaire created by the authors. Results. All respondents positively assessed their appearance after surgery. In most cases they pointed out the positive impact of treatment on their self-confidence (82.9% of responses). The vast majority of respondents felt improvement in biting off food (91.4%). Conclusions. Patients positively evaluate the outcome of surgical treatment with extraoral vertical ramus osteotomy. The subjective improvement of the facial appearance, as well as chewing and articulation functions took place after the treatment.

Opis:
Purpose: This study aimed to analyze the changes of the stress distributions in TMJs for the pre- and postoperative patients with mandibular prognathism under unilateral occlusions, a frequent occlusion in mastication. Methods: Pre- and six-mouth postoperative cone-beam computed tomography images of thirteen patients diagnosed with mandibular prognathism were scanned and used to construct complete maxillofacial models, assigned as the Pre and Post group, respectively. Another ten asymptomatic individuals were defined as the Control group. The inhomogeneous properties were assigned to the models. The muscle forces and boundary conditions corresponding to left and right unilateral occlusions were applied on the models. The analysis of variation (ANOVA) was chosen for the comparison among the groups. Results: The results showed that the Pre group had abnormal stress distributions ang higher stress level in TMJs, compared with those of the Post and Control groups. Moreover, from clinical cases, symptoms of temporomandibular disorders (TMDs) always followed with increased stresses. Conclusion: Generally, orthognathic surgeries could improve the stress distribution in TMJs of the patients with mandibular prognathism under the unilateral occlusions. However, the postoperative complications, especially symptoms of TMD, were closely related to changes of stress for patients with mandibular prognathism after orthognathic surgeries. Individual virtual surgery and finite element analysis should be conducted to prevent complications in TMJ.
