The postoperative courses of 58 patients who underwent orthognathic surgery between 1 January 2004 and 31 December 2017 were analyzed. Each different complication prevalence rates are presented in Table 1. A total of 6.90% of patients were preoperatively affected by a temporomandibular disorder; this consisted of bilateral joint pain in three patients, in joint clicks at the left TMJ level in one patient. Globally, this group consisted of three women and a man. Initial diagnoses were [PERSON]'s third-class malocclusion in three patients, [PERSON]'s second class in one patient. One patient also presented latero-deviation to the right. None of the patients in this study had obstructive sleep apnea syndrome (OSAS) prior to surgery. In 18 patients, no complications occurred (31.03%). Forty postoperative complications were identified in the remaining cohort. TMJ Disorders: Fourteen patients (24.14%) developed a disorder related to the temporomandibular joint. TMJ disorders occurred mainly in male subjects (57.15%) and with an initial diagnosis of [PERSON]'s third-class malocclusion (71.42%). Of these patients, pain within the TMJ was reported in five cases. The presence of joint noises, also called joint clicks, was reported in eight patients out of fourteen with TMJ disorders (M:F = 2:6). Of these, 75% had an initial diagnosis of [PERSON]'s third-class malocclusion, the remaining 25% were affected by [PERSON]'s second-class malocclusion. In two patients, there was a limitation during mouth opening, while in only one patient, a left lateral restriction occurred, associated with a left click. In four patients, joint disorders were present before orthothothoth surgery (6.90%). Two of these cases were solved by the intervention. Paraesthesia: The presence of postoperative paraesthesia was highlighted in thirteen patients (M:F = 9:4). The prevalence was 22.41%. Only three of these patients underwent genioplasty as an ancillary procedure of orthognathic surgery. In eight cases, the paraesthesia was present at the jaw level; in the remaining five patients, it was localized at the maxilla. A case of temporary paraesthesia at the level of the half palate and one at the level of the auricle were also reported. In seven patients, paresthesia disappeared spontaneously: within one year of operation for four subjects and after more than one year for the three other subjects. Hypoesthesia: We found a prevalence of cases of hypoesthesia equal to 12.07% (M:F = 5:2). In all cases, it was located at the jaw level. It was solved in five patients, while it was still present in two of them at the time of follow-up, eight and four years after the intervention, respectively. \begin{table}

Table 1: Complication prevalence rates after orthognathic surgery. Asymmetries: Eight patients (13.79%) reported perceiving their face as asymmetric. All patients rated this asymmetry as mild. It seemed to be perceived by patients on average 50 months after surgery. Enlargement of the Nasal Wing: No cases of enlargement of the nasal wing were reported. Spetal Deviation: No cases of septal deviation were reported.
