ABSTRACT

Introduction: More than 15 years of experience in orthodontic-surgical collaboration has allowed the authors to identify some situations in which a new perspective is needed. Although it may seem easy to refer a patient to a maxillo-facial surgeon in cases of major dysmorphoses, this can lead to yet other dilemmas: a loss of results at the end of a developmental growth stage, an adult requesting a return to treatment after a camouflage orthodontic treatment or a non-cooperative child in an interceptive and preventive treatment phase. Then, a comprehensive process of reassessment becomes compulsory. Material and Method: In the form of an editorial, this article describes various cases encountered in the authors' practice. Discussion: The aim is not to point out the imperfections of our humanity, but simply to open our eyes to diagnostic elements that are missed, whether in the initial phase or during reassessment. Conclusion: As it is far from ideal to keep offering similar therapies that lead to the same pitfalls, it is time for a shift in the paradigm.


Introduction: Plus de 15 ans de recul en collaboration orthodontico-chirurgicale ont permis aux auteurs d'identifier un certain nombre de situations dans lesquelles un regard différent est devenu opportun. S'il est aisé d'orienter un patient vers un(e) chirurgien(ne) maxillo-facial(e) en cas de dysmorphoses majeures, les orthodontistes sont régulièrement confrontés à d'autres dilemmes : une perte de résultat en fin de croissance, un adulte demandeur d'une reprise après un traitement en compensation ou encore un enfant non-coopérant en phase interceptive. Une phase de réévaluation exhaustive devient alors nécessaire. Matériel et méthode: Sous la forme d'un éditorial, cet article expose différentes situations cliniques auxquelles les auteurs ont été confrontés lors de leur pratique. Discussion: Le propos n'est pas de pointer les imperfections de notre humanité mais seulement d'ouvrir les yeux sur des éléments diagnostiques qui échappent, que ce soit en phase initiale ou en réévaluation. Conclusion: Offrir une thérapeutique identique conduisant aux mêmes écueils n'est pas acceptable : il est temps de changer de paradigme.

ABSTRACT

AIMS: The study aimed at analyzing patient's case sheets in regard to the incidence of skeletal discrepancy present in cases and its relation with the demographic profile of the sample. All these are chronicled for more than 10 years periods. METHODOLOGY: This is a retrospective study analysis of the orthognathic case sheets for more than 10 years period. The total numbers of patients are 678. Patient's case sheet was already prepared by the Multi-Disciplinary Team Orthognathic Surgery Clinic in Al-Salam Teaching Hospital, which is the only authorized committee in Nineveh Health Directorate. RESULTS: The highest age percentage is between (18 and 27 y/76%). Angle class III cases are the uppermost cases (36%) from the total. A significant P value is clear at the level ≤0.05 and ≤0.01 between surgery type and discrepancy in anterior segmental osteotomies (upper and lower) which is performed in bi-maxillary protrusion cases and Angle class II cases (0.01**). Similarly, anterior segmental osteotomies (upper jaw only) which are indicated in both open bite and Angle Class II cases documented as a statistically significant P value (0.02*). The positive correlation is shown in all variables with the disharmony or facial discrepancies. Esthetic and beauty as causes for treatment recorded more than function in relation to time series. CONCLUSION: This study documents that patients with skeletal class III accounted for the largest percentage (64%) in the study group. A high increase in patients number seeking treatment for their discrepancy is obvious with time from 2009 till 2022.

ABSTRACT

INTRODUCTION: Class II malocclusion with mandibular retrognathia is a common complication of paediatric obstructive sleep apnoea (OSA), often accompanied by transverse maxillary deficiency. In early orthodontic treatment, a twin block (TB) is a regular functional appliance for correcting this malocclusion. For paediatric OSA, the most common risk factor is adenotonsillar hypertrophy (AHT). Untreated AHT may lead to the persistence and worsening of obstructive sleep-disordered breathing traits, including habitual mouth breathing. Additionally, the clockwise mandibular rotation associated with AHT-induced pharyngeal crowding can undermine the effectiveness and stability of TB treatment. Adenotonsillectomy (T&A) is currently the first-line treatment for paediatric OSA. This proposed trial will investigate the impact of T&A surgery timing on the efficacy and stability of TB functional treatment in children with class II mandibular retrognathia and ATH. METHODS AND ANALYSIS: This will be a single-centre, parallel-group, superiority randomised controlled trial with participants randomised to intervention (T&A followed by TB treatment) or control arms (TB treatment followed by T&A) in a 1:1 ratio. A total of 40 patients aged 8-14 years, diagnosed with class II mandibular retrognathia and co-existing ATH-induced OSA, and indicated for both T&A surgery and TB treatment, will be recruited at the School and Hospital of Stomatology, Wuhan University. The primary outcomes will be the changes in the apnoea-hypopnoea index and the point A-nasion-point B angle from baseline to postorthodontic treatment between the two groups. Secondary outcomes will include other dental, skeletal, upper airway and soft tissue changes, as well as subjective sleep-related and oral-related quality of life. Outcome changes within each group and between groups will be analysed. ETHICS AND DISSEMINATION: This study is approved by the Ethics Committee of the School and Hospital of Stomatology, Wuhan University (no. 2022-D07). The research findings will be faithfully disseminated through scientific conferences or published articles. TRIAL REGISTRATION NUMBER: ChiCTR2200061703 (https://www.chictr.org.cn).

ABSTRACT

Background: There are still many doubts about anterior inferior crowding and indications of mandibular third molar extraction, although it is very studied subject in the literature. The aim of this study was to evaluate the perceptions of oral maxillofacial surgeons (OMFSs) and orthodontists about anterior inferior crowding and indications of mandibular third molar extraction. Material and Methods: A web-based survey was developed and sent to professionals in order to collect their opinion about the fact that third lower molars cause crowding and questions about the indication of third molars for orthodontic treatment. Descriptive analysis was performed and Chi-square or G tests were applied with a 95% confidence interval. Results: The study included a total of 218 participants, of whom 115 were OMFSs and 103 were orthodontists. The results showed that 56.5% of OMFSs and 35.0% of orthodontists believe that the lower third molars cause anterior inferior crowding (p<0.001). A total of 91.3% of OMFSs and 70.9% of orthodontists indicate the extraction of lower third molars to aid orthodontic treatment (p<0.001). Conclusions: It can be concluded that in being an oral maxillofacial surgeon, a higher odds ratio is observed to consider that lower third molars cause dental crowding compared to those who are orthodontist. The indication of exodontia of lower third molars for orthodontic treatment was more frequent among OMFSs when compared to orthodontists.(AU)

ABSTRACT

Caudal malocclusions in cats may result in a variety of traumatic lesions affecting the soft tissues of the ipsilateral mandible such as fovea, gingival cleft, and proliferative lesions. Fifty-one cats diagnosed with a traumatic caudal malocclusion were compared with a control hospital population and evaluated for prevalence with respect to breed and sex. Twenty-two cats that were treated had radiographic, clinical findings, and the outcome of treatment (extraction or odontoplasty) recorded. Maine Coon, Persian, and male neutered cats were overrepresented while Domestic Shorthairs were underrepresented within the study population. Radiographically, 50% of the fovea lesions had an area of decreased bone density in the region of the lesion and none of these had evidence of periodontal disease. All gingival cleft lesions had radiographic changes consistent with periodontal disease. 15.4% of proliferative lesions presented with radiographic changes, with only half of those presenting with both radiographic and clinical evidence of periodontal disease. Eleven cats were treated by odontoplasty and eleven by extraction. One cat treated by odontoplasty developed new lesions caudally, and another had persistence of the initial lesions. Two cats in the extraction group developed new lesions rostral to the extracted teeth. In most instances, odontoplasty or extraction resulted in successful soft tissue lesion resolution. In rare cases, additional treatment was necessary due to either persistence or development of new lesions.

ABSTRACT

Linguoverted mandibular canine teeth (LMC) are a common cause of class 1 malocclusion, which may result in a traumatic occlusion. When deciduous LMC are diagnosed, extraction is commonly performed to alleviate traumatic occlusion. This retrospective study was designed to observe the outcome of the permanent dentition in dogs with a class 1 malocclusion receiving treatment for deciduous LMC. Medical records from a veterinary dental referral hospital were used to identify patients that underwent extraction of deciduous LMC's prior to the eruption of the permanent mandibular canine teeth. The permanent occlusion was then evaluated once the permanent mandibular canine teeth were erupting. Of the 28 dogs identified and treated for deciduous LMC's, 78.6% (22/28) had a normal permanent occlusion. The 6 patients identified with permanent LMC's were all diagnosed when the patients were between 20 and 29 weeks of age. Of these 6 patients, 5 received gingivectomy and gingivoplasty treatment to correct the permanent LMC. Treatment was declined by the pet owner of the sixth patient. Overall, the majority of dogs in this study with a class 1 malocclusion and deciduous LMC's treated with extractions prior to the eruption of the permanent mandibular canine teeth had a normal permanent occlusion.

ABSTRACT

INTRODUCTION: This study aimed to investigate changes in bite force (BF) and occlusal contact area after anterior open-bite (AOB) treatment and compare the changes in surgical vs nonsurgical treatment. METHODS: This retrospective study included patients with AOB compared with normal occlusion. AOB was corrected by either intrusion of the maxillary molars (intrusion group, n = 19) or orthognathic surgery (surgery group, n = 37). The control group (n = 35) had a normal overbite relationship. Records of lateral cephalograms, BF, and occlusal contact area taken before (T0), immediately after (T1), and 2 years after (T2) orthodontic treatment were compared within and among the 3 groups. RESULTS: The open-bite group, including intrusion and surgery groups, had a lower BF and less occlusal contact area than the control group at T0 and T1 (P <0.001). However, there were no significant differences among the 3 groups at T2 (P >0.05). The intrusion and surgery groups showed no significant differences throughout the observation period extending from T0 to T2 (P >0.05). Although BF and occlusal contact area decreased at T1 compared with T0, they increased during retention and showed higher values at T2 than at T0. CONCLUSIONS: Treatment of AOB improved BF and occlusal contact area 2 years posttreatment. Orthognathic surgery and molar intrusion using orthodontic miniscrews can improve occlusal function similarly. Orthodontists can select either method depending on malocclusion severity and patient demand.

ABSTRACT

OBJECTIVE: This study aims to determine the occurrence of complications before and after the treatment of facial fractures, as well as the impact of the factors on the treatment results and evaluation of their relationships. PATIENTS AND METHODS: This is a prospective case-control study comprising 90 patients aged between 18 and 65 with facial fractures. Depending on the treatment method, patients were divided into three groups: those treated surgically using a transcutaneous approach, those treated surgically using a transmucosal approach, and those treated conservatively (control group). Following complications before and after treatment were compared: malocclusions, paresthesias, facial asymmetry, diplopia, and limited mouth opening. The follow-up period after the treatment of choice was six months. RESULTS: There was a significant reduction in complications after treatment: malocclusion, paresthesia, facial asymmetry, and limited mouth opening. Regarding the transcutaneous approach, there is a substantial reduction in the number of complications after treatment, such as malocclusions (p=0.008), paresthesias (p=0.004), and facial asymmetries (p<0.001). Similar results were obtained for the transmucosal approach. Pain intensity positively correlated with preoperative complications: malocclusion, paresthesias, and facial asymmetry. The range of mouth opening had a negative interdependence with malocclusion before and after treatment with infection, fractura male sanata, malocclusion, paresthesias, postoperative level of mouth opening, and damage to the facial nerve. CONCLUSIONS: There is no difference in the reduction of preoperative and postoperative complications related to surgery when an incision is made through the skin or mucosa. Malocclusions, paresthesias, and facial asymmetry are reduced through surgical methods.

ABSTRACT

BACKGROUND: Open reduction internal fixation (ORIF) of mandibular subcondylar fractures (MSF) involves several variables that could affect decision making. There is insufficient data regarding factors influencing the outcomes of MSF ORIF. PURPOSE: The purpose of this study was to investigate factors associated with quality of bony reduction of MSF and occlusion, after ORIF. STUDY DESIGN, SETTING, AND SAMPLE: We designed a retrospective cohort study of consecutively treated subjects for MSF ORIF, ages 18 to 64 years, by University of Illinois' Department of Oral and Maxillofacial Surgery, between January 1, 2013, and January 26, 2021. PREDICTOR VARIABLE: The primary predictor variable was the vertical level of MSF from the gonial angle. Secondary predictor variables included surgeon, fixation scheme (number and configuration of miniplate), surgical approach, time to surgery, mechanism of injury, vertical fragment overlap, overlying soft tissue thickness, presence of other mandibular fractures, and severity and direction of displacement. MAIN OUTCOME VARIABLES: The primary outcome variable was the mean radiographic reduction score (RRS), rated by 2 blinded observers on a 1 to 5 scale. The secondary outcome variable was presence of postoperative malocclusion as documented in the medical records. COVARIATES: Covariates were age and sex. ANALYSES: Descriptive statistics were computed. To investigate the influence of the predictor variables on reduction quality, multifactorial analysis of variance with post hoc Tukey test was performed. For malocclusion, χ2 test was performed. The level of significance was set at P < .05. RESULTS: Thirty-eight MSF in 37 subjects were included. Mean age was 32.7 years (range 18 to 64), and 83.8% were male. Mean RRS was 4.38 (standard deviation 0.77). Fixation scheme was the only variable that showed significant impact on RRS: single-straight miniplate had lower scores than double-straight (-1.50, P = .011), rhomboid (-1.29, P = .036), and ladder miniplates (-1.38, P = .048). There was 1 incidence of malocclusion (2.7%) which resolved without intervention. CONCLUSIONS AND RELEVANCE: Favorable reduction (anatomic reduction to mild discrepancies) can be achieved without malocclusion using double-straight, or rhomboid-shaped or ladder-shaped miniplates, without influences from patient or injury-related factors. In contrast, single-straight miniplate fixation resulted in moderate discrepancies in reduction, although it did not lead to malocclusion.

ABSTRACT

AIM: The aim of this study was to retrospectively investigate the risk factors and their association on bimaxillary osteotomies to be able to improve patient selection and bimaxillary osteotomy planning. MATERIAL AND METHODS: Patients treated with a bimaxillary osteotomy were included in the study. The complications were collected retrospectively from the patient data records. The effects of certain predictor variables on complication rates were also studied. RESULTS: Sixty-one patients (48.0%) suffered from peri- or postoperative complications, or both. Twenty-five various perioperative complications were reported on 25 patients (19.6%) and 63 postoperative complications on 46 patients (36.2%). Ten patients (7.8%) suffered from both perioperative and postoperative complications. The effect of various predictor variables (sex, age, general health, type of malocclusion, surgery planning, use of bone grafts, and type of maxillary or mandibular movement) on complications was investigated, but we could not find any single factor to affect significantly on complication rate. CONCLUSION: Both perioperative and postoperative complications are common in bimaxillary surgery, which must be noted in patient preoperative information. However, life-threatening complications are rare. Patient profile, bone grafting, type of osteosynthesis, or segmentation of the maxilla do not seem to affect the complication risk.

ABSTRACT

BACKGROUND: Unilateral surgically assisted rapid maxillary expansion (U-SARME) is a successful method for correction of true unilateral posterior crossbite (TUPC). OBJECTIVES: This retrospective preliminary study aimed to evaluate the position and morphology of condyles in TUPC cases and the effects of U-SARME on condyle with the help of cone beam computed tomography (CBCT). METHODS: Fifteen patients (mean age: 18.69 ± 1.59 years) who were diagnosed as TUPC and undergone U-SARME were selected. Preoperative (T0) and after 6-month retention (T1) DICOM data of CBCT images were evaluated with MIMICs version 19.0 software. Condylar morphology (medio-lateral and antero-posterior dimensions) and position (anterior, posterior, medial and lateral joint spaces, frontal/axial axis angles, the ratio of posterior to anterior joint space and the percentage of posterior to anterior joint space) were evaluated. Student's t-test was used for intergroup (crossbite, normal) comparisons. Paired-samples t-test was used for intra-group comparisons (p = .05). RESULTS: There were no positional or dimensional asymmetry of the condyles between crossbite and normal sides initially and after expansion. Regarding T0-T1 changes, while significant increase was determined in medial (0.3 ± 0.29 mm; p = .001) and superior (0.39 ± 0.7 mm; p = .045) joint spaces on crossbite side, posterior (0.79 ± 0.99 mm; p = .008), superior (0.5 ± 0.79 mm; p = .029) and lateral joint spaces (0.31 ± 0.54 mm; p = .042) presented significant increases on normal side. However, no significant changes were found between crossbite and normal sides at T0 and T1. CONCLUSIONS: Condyles were symmetrical in true unilateral posterior crossbite cases and the symmetry were not disrupted following U-SARME.

ABSTRACT

Maxillary transverse deficiency can occur in various clinical dentoskeletal deformities and include unilateral or bilateral posterior crossbite, narrow, tapering, or high palatal arch. The development of temporary anchorage devices led to a new generation of tooth-bone-borne expansion appliance using two or four screws to apply the mechanical forces to the bone and reduce the stress to the anchored teeth. The aim of these new devices is to reduce the adverse dentoalveolar effect and achieve more skeletal expansion than conventional tooth-borne rapid palatal expansion. This article reviews the age limitation and complication and soft tissue change of nonsurgical maxillary expansion. We discuss the approach of surgical maxillary expansion with maxillary skeletal expander device. The clinical case will show the benefit of nonsurgical and surgical tooth-bone-borne rapid palatal expansion.

ABSTRACT

Orthognathic surgery, also known as corrective jaw surgery, is a procedure that corrects abnormalities of the jaw and face. It is used to treat malocclusions, where the teeth and jaws are misaligned. This surgery can improve the function and appearance of the jaw and face, leading to improved mastication, speech, and quality of life for the patients. To assess if social media had any effect on the patients' decision to undergo orthognathic surgery, a self-administered online questionnaire was distributed to patients who had undergone orthognathic surgery at the Oral and Maxillofacial department through the health information system (BESTCare, 2.0A) to participate in the study. In total, 111 responses were recorded from the patients, with 107 agreeing to answer the questionnaire and 4 refusing to answer. Twitter was a source of information about orthognathic surgery for 61 patients (57%). When using a social media platform, 3 patients (2.8%) were influenced by an advertisement or an educational post on social media that presented the surgical correction of the jaws, while 15 (14%) believed that they had been somewhat influenced, and 25 (23.4%) picked their surgeon through social media. Fifty-six patients (52.3%) took the neutral position regarding whether information on social media had answered their questions and concerns regarding the surgical procedure. Social media did not influence patients' decision to undergo the procedure. Surgeons and specialists must utilize their platforms to answer any concerns or questions from any patient undergoing or having undergone this corrective jaw surgery.

ABSTRACT

OBJECTIVE: To look into the association between the degree of deviation and the changing trend in the temporomandibular joint (TMJ) space volume after orthognathic surgery in patients with skeletal Class III malocclusion. METHODS: Twenty patients having combined orthodontic-orthognathic treatment for skeletal Class III malocclusions with mandibular deviation were chosen, and craniofacial spiral CT was performed before (T0), two weeks after (T1), and six months after (T2) surgery. Using 3D volume reconstruction, further partitioning, and analysis of each domain's volume changes over time, the TMJ space volume is to be obtained. The differences in changes between groups A (mild deviation group) and B (severe deviation group) were examined to examine the impact of the degree of deviation on the TMJ space volume. RESULTS: A statistically significant difference ( P <0.05) existed between the postoperative TMJ space volume in group A and the preoperative overall, anterolateral, and anteroinferior space volume; the same difference also existed between the postoperative TMJ space volume in the NDS and the preoperative posterolateral, posteroinferior space volume. In group B, the postoperative TMJ space volume was statistically significant ( P <0.05) compared with the preoperative total and anteroinferior space volume in the DS; the difference between the total volume of the T1 stage on the NDS and the total volume of the T0 stage was statistically significant ( P <0.05). The two groups showed substantial differences in the space volume changes between the T1-T0 phase and the T2-T1 period. CONCLUSION: Patients with skeletal Class III malocclusion and mandibular deviation after orthognathic surgery see a change in the TMJ space volume. All patient types experience a largely consistent space volume change trend two weeks after surgery, and the degree of mandibular deviation is correlated with the intensity and longevity of the alteration.

ABSTRACT

OBJECTIVE: Unilateral posterior scissors-bite (uPSB) malocclusion is common clinically. This study aimed to investigate the condylar morphological alterations and condyle-fossa relationship in patients with uPSB, through cone beam computed tomography (CBCT) and three-dimensional reconstructive imaging technique. METHODS: A retrospective study was designed to comparatively analyze 95 patients with uPSB between July 2016 and December 2021. They were divided into three subgroups: 12 to 20, 21 to 30, and ≥ 31 years, according the age distribution. The morphological parameters regarding condyle, fossa, and joint space after three-dimensional reconstruction were measured and analyzed by a series of digital software. SPSS 26.0 software package was performed for statistical analysis on data sets, using paired t-test, one-way analysis of variance, Wilcoxon signed-rank sun test, Kruskal-Wallis H test, and Bonferroni correction. RESULTS: The condylar volume (CV) of scissors-bite side was greater than that of the non-scissors-bite side (CV A = 1740.68 ± 559.80 mm3 > CV N = 1662.25 ± 524.88 mm3, P = 0.027). So was the condylar superficial area (CSA) (CSA A = 818.71 ± 186.82 mm2 > CSA N = 792.63 ± 173.44 mm2, P = 0.030), and the superior joint space (SJS) [SJS A = 2.46 (1.61, 3.68) mm) > SJS N = 2.01 (1.55, 2.87) mm), P = 0.018], and the anterior joint space (AJS) (AJS A = 3.94 ± 1.46 mm > AJS N = 3.57 ± 1.30 mm, P = 0.017). The constituent ratios of the different parts of the bilateral condyles were 23% on the posterior slope, 21% on the top, 20% on the anterior slope, 19% on the lateral slope and 17% on the medial slope, respectively. CONCLUSION: Due to long-term abnormal occlusion of uPSB, the pathological bite force in temporomandibular joint would cause changes in the shape of the condyle. Among them, CV, CSA, SJS and AJS had significant changes in the scissors-bite status, which has the greatest damage to the posterior slope of the condyloid process.

ABSTRACT

Different temporary anchorage device (TAD)-assisted rapid palatal expanders may be used to treat malocclusions involving the transverse dimension and, in many instances, prevent more complex situations in the future. Each style of expander has advantages and disadvantages. The acrylic type of TAD-supported palate lateral wall expander is a reliable and cost-effective appliance for expansion treatment in adolescents and young adults (ie, aged 13 to 21). In comparison, other palatal expander designs are more suitable for older patients. One advantage of an acrylic TAD-supported palate lateral wall expander system is that it can be used for both orthopedic expansions (ie, nonsurgical TAD-supported only) and surgically assisted rapid palatal expansions (ie, with the aid of minimally invasive corticotomies) in patients who do not respond to nonsurgical expansion. This article presents general diagnostic considerations regarding maxillary transverse deficiencies, discusses the importance of palatal expansion in managing malocclusions, and describes protocols for nonsurgical and surgical management of transverse deficiencies with an acrylic TAD-supported virtually guided palate lateral wall expander.

ABSTRACT

PURPOSE: The aim of this case-control study was to investigate occlusal characteristics, received orthodontic treatment, oral health-related quality of life (OHRQoL), and satisfaction with dental esthetics in adults operated due to sagittal synostosis. METHODS: The study group consisted of 40 adults (25 males, 15 females, mean age 27.4 years, range 18-41) who were operated due to isolated sagittal synostosis in childhood. The control group comprised 40 age and gender-matched adults. Occlusal characteristics were evaluated clinically during study visits. Information on the previous orthodontic treatment was collected from dental records. OHRQoL was measured using the 14-item Oral Health Impact Profile (OHIP-14), and satisfaction with dental esthetics was evaluated using a visual analogue scale. RESULTS: No statistically significant differences were found between the patient group and the controls in malocclusion traits (overjet, overbite, molar relationships, crossbite, scissor bite), previous orthodontic treatment, pre-treatment malocclusion diagnoses, OHIP variables, or satisfaction with dental esthetics. However, there was a tendency toward increased overjet and overbite in scaphocephalic patients. CONCLUSION: It seems that adults with scaphocephaly operated in childhood do not differ from the average population in terms of occlusion, received orthodontic treatment, or oral health-related well-being.

ABSTRACT

The aim of this study was to investigate the underlying causes of the need for redo orthognathic surgery, address surgical strategies, and evaluate postoperative outcomes. A retrospective chart review was conducted involving patients who underwent redo orthognathic surgery between January 2018 and April 2020. A total of 32 patients were included in this study. Prior to the procedures, patients' chief complaints were unfavorable facial profile, asymmetry, relapse, malocclusion, obstructive sleep apnea, and long face. To address these issues, we performed redo orthognathic surgery: this resulted in satisfactory aesthetic and functional outcomes in most cases. Considering the challenging nature of a redo orthognathic surgery, it is crucial for surgeons to accurately evaluate the patient's chief complaints and tailor individualized surgical plans to meet the patient's expectations.
