Assessment of the Epidemiological Profile of Patients With Dentofacial Deformities Who Underwent Orthognathic Surgery

Abstract

The present study aimed to establish the profile of patients who underwent orthognathic surgery in a private clinic by evaluating their demographic characteristics, their facial types, and aspects related to the surgical procedures that were performed. The sample consisted of 419 medical records from male and female patients aged 15 to 62 years who underwent orthognathic surgery between 2001 and 2011. A single examiner collected data by evaluating a database of information extracted from medical records, particularly radiographic and photographic analyses. The following criteria were evaluated: gender, age, skin color, type of orthognathic surgery, type of associated temporomandibular joint (TMJ) surgery, complications, and recurrences. Seventeen patients were rejected because they had incomplete records. The average age of the patients was 28.5 years old; most were females (255 patients) and faioderm (295 patients). The most prevalent facial pattern was Pattern III (n = 166, 41.3%). Orthognathic surgery that affected the maxilla, jaw, and chin was the most prevalent type (n = 199, 49.5% of cases). A genioplasty was performed concurrently with combined surgeries and single-jaw surgery in 76.86% of patients (n = 309). TMJ surgery was performed concomitantly with orthognathic surgery in 4% of cases (n = 16). The most common postoperative complication was infection/inflammation (n = 12). We concluded that there was a higher frequency of orthognathic surgery among women and young people, the brunette skin phenotype was prevalent, and most patients had a combination of maxillary and mandibular problems.

Orthognathic Surgery

“…Generally, a higher frequency of OS is seen among women and young patients. [34][35][36] In addition, studies have a larger number of women than men. 5,11,12,37 Some studies find a female:male ratio of 2:1.…”

Orthognathic Surgery Treatment Need in a Turkish Adult Population: A Retrospective Study

“…In the case of sleep apnea, genioplasty is sometimes applied for functional purposes. Castro et al [21] found a high frequency of chin surgery (76.86%) either isolated or in combination with maxillary or mandibular surgery. In this study, the prevalence of isolated genioplasty was 1%, and the prevalence of genioplasty in combination with other osteotomies was 26%, which is higher than the previously reported studies [19,22,23].…”

Comparison of one-jaw and two-jaw orthognathic surgery in patients with skeletal Class III malocclusion using data from 10 multi-centers in Korea: Part I. Demographic and skeletodental characteristics

“…Although the dominance of 2J-OGS was coincident with the results of previous studies, the percentage of 2J-OGS in our study was somewhat higher than those reported in studies of other countries. [5][6][7][8] This could be attributed to the differences in ethnic features, since severe skeletal Class III malocclusions are more prevalent in the Asian population than in African Americans, Native Americans, and Hispanics populations. [16][17][18] When compared with the previous studies on Korean patients, both similarities and differences could be noted in the results of this study.…”

“…1,2 The most prevalent skeletal discrepancy of the patients undergoing orthognathic surgery has been reported as skeletal Class III malocclusions. [3][4][5][6][7][8][9] This is also demonstrated in the Korean population, which has a high prevalence of Class III malocclusions and a negative social perception of the prognathic appearance. [9][10][11][12][13][14][15][16][17][18] Therefore, Korean has become one of the countries performing orthognathic surgery extensively in patients with skeletal Class III malocclusions.…”
