RESUMO

OBJECTIVES: Gingivoperiosteoplasty is often used for reconstruction of alveolar defects in infants with cleft lip and palate. This study aimed to examine outcomes of tertiary gingivoperiosteoplasty, which has not previously been investigated. MATERIALS AND METHODS: This prospective study included 11 adults with complete cleft lip and palate (n = 12 sites) who consecutively underwent segmental Le Fort I osteotomy and concomitant gingivoperiosteoplasty for correction of skeletal class III deformity, nasoalveolar fistula and alveolar cleft. Outcomes included clinical and radiographic evaluations of gingivoperiosteoplasty at the time of osteotomy (presence of nasoalveolar fistula, residual cleft defect and unsupported root ratio of cleft-adjacent teeth), and determination of influencing factors for the clinical success of alveolar cleft repair. Study variables included age, gender, pre-surgical orthodontic treatment and alveolar cleft width of cleft-adjacent canine and angulation between cleft-adjacent teeth before surgery and 1-week postsurgery. RESULTS: Posttreatment, no nasoalveolar fistula remained. The residual cleft defect decreased significantly (p < 0.01). The unsupported root ratio of cleft-adjacent teeth did not differ (p > 0.05); eight cleft sites reached Bergland I or II (67% success). One-week postsurgery, the minimal alveolar cleft width of cleft-adjacent canine was significantly less in the success group compared with the failed group (p = 0.01). CONCLUSIONS: Tertiary gingivoperiosteoplasty and segmental Le Fort I osteotomy decreased nasoalveolar fistulas and induced alveolar bone formation. The minimal alveolar cleft width immediately after surgery was the major influencing factor of clinical success. CLINICAL RELEVANCE: Segmental Le Fort I osteotomy with simultaneous gingivoperiosteoplasty efficaciously repairs adult alveolar clefts.

RESUMO

BACKGROUND: The concept of gingivoperiosteoplasty (GPP) in the mixed dentition stage as compared with secondary alveolar bone grafting (ABG) in management of alveolar cleft has not been much discussed upon. The authors present the experience with extensive GPP and ABG in the mixed dentition stage in complete bilateral alveolar cleft cases. METHODS: A retrospective review of nonsyndromic patients with complete bilateral alveolar cleft operated on with either GPP or ABG (iliac crest) in the mixed dentition stage with at least 1-year follow-up was performed. Dental occlusal radiographs were evaluated for level of bone gain using Bergland and Witherow scales. Statistical evaluation of clinical success and procedure-related complications was conducted using χ2 test and odds ratio. RESULTS: Twenty-four patients in the GPP group and 20 in the ABG group were comparatively studied. Clinical success rate as indicated by Bergland scales I and II (87.5% in GPP vs 82.5% in ABG; P = 0.731), complication rate (20.83% in GPP vs 30% in ABG; P = 0.484), and status of canine eruption showed no significant differences in clinical outcomes in both groups. CONCLUSIONS: The technique of extensive GPP as described by authors shows equal efficacy to secondary ABG for management of bilateral alveolar clefts during the mixed dentition period.

RESUMO

OBJECTIVES: Some adults with cleft lip and palate (CLP) require orthognathic surgery due to skeletal deformity. This prospective study aimed to (1) compare skeletal stability following bimaxillary surgery for correction of class III deformity between patients with unilateral CLP (UCLP) and bilateral CLP (BCLP), and (2) identify risk factors of stability. MATERIALS AND METHODS: Adults with CLP and skeletal class III deformities who underwent surgery-first bimaxillary surgery were divided into two groups according to cleft type: UCLP (n = 30) and BCLP (n = 30). Skeletal stability was assessed with measures from cone beam computed tomography images of the maxilla and mandible taken before treatment, 1-week and ≥ 1 year postsurgery for translation (left/right, posterior/anterior, superior/inferior) and rotation (yaw, roll, pitch); multiple regression analysis examined risk factors. RESULTS: At follow-up, the maxilla moved upwards in both groups, and backwards in the UCLP group. The mandible moved forward and upward, shifted to the cleft (deviated) side, and rotated upward in both groups. The amount of surgical advancement was a risk factor for sagittal stability in the maxilla (ß = -0.14, p < 0.05). The mandible had three risk factors for sagittal stability: age (ß = -0.23, p < 0.05), surgical team (ß = -1.83, p < 0.05), and amount of surgical setback (ß = -0.32, p = 0.001). CONCLUSIONS: Two years after bimaxillary surgery, patients with UCLP had a higher sagittal relapse of the maxilla compared with patients with BCLP, which was due to a greater surgical advancement in the patients with UCLP. CLINICAL RELEVANCE: Surgery-first bimaxillary surgery results in favorable treatment outcomes for correction of cleft-related class III deformity. Severity of jaw discrepancy and surgeons should be considered in the surgical design of overcorrection.

RESUMO

BACKGROUND: Midface retrusion is a common problem in patients with cleft lip and palate owing to the lack of adequate growth of the maxilla. Midface advancement surgery is a definite treatment for midface retrusion; however, the subsequent oropharyngeal airway changes might result in velopharyngeal insufficiency (VPI) in affected patients. Determining the predictors of VPI beforehand and modifying the surgical procedure would be beneficial. MATERIALS AND METHODS: A retrospective review of 42 patients with cleft lip and palate who underwent orthognathic surgery from 2013 to 2014 was performed. A total of 25 patients met the inclusion criteria and had undergone complete pre- and postsurgery videofluoroscopy, nasopharyngoscopy (NPS), and speech assessment. We compared 2 groups of patients, those who showed NPS finding changes of more than 0.1 (8 patients) and those without changes (17 patients), by measuring the distances of the contact point to the tip of the velum, gap size at maximum closure (MC) and rest, contact area length, lateral wall closure rate, closure velocity, and 2 angles (from the velum to the hard palate and genu) at MC and rest. The amount of maxillary advancement was also recorded. RESULTS: Among the 8 patients with NPS finding changes, 3 underwent Furlow palatoplasty for VPI. No significant difference was found in the amount of maxillary advancement between the groups (5.8 vs 5.7 mm). Significant differences were found in the preoperative gap size at MC and angle at the genu at MC (P = 0.035 and .012). These could be considered as the predictors before surgery. After surgery, a significant difference was found in the contact area, lateral wall closure rate, and gap size at MC (P = 0.005, 0.018, and 0.01). CONCLUSION: Videofluoroscopy is a relatively applicable method of determining dynamic changes in the velum function. By performing videofluoroscopy before midface advancement surgery in patients with cleft lip and palate, we may predict the risk of VPI and consider alternative surgical strategies.

RESUMO

BACKGROUND AND AIM: It is well known that palatoplasty can often cause disturbances in maxillary growth. The use of a single-layer vomer flap for the early closure of the hard palate is controversy among surgeons. The aim of this study is to compare the 10-year facial growth of 2 surgical protocols in the treatment of patients with unilateral cleft lip and palate performed by a single surgeon. METHODS: This retrospective analysis includes 43 nonsyndromic patients with complete unilateral cleft lip with or without a vomer flap for the closure of the hard palate during cleft-lip repair. Lateral cephalograms were obtained at the age of 5, 7, and 9 years old, and angular measurements were used to assess patient's facial growth. The Mann-Whitney U test was used to compare 2 treatment protocol groups. RESULT: A total of 23 patients in protocol 1 group (16 male, 7 female) and 20 patients in protocol 2 group (10 male, 10 female) were included. At the age of 5 and 7, there was no significant difference of maxillary and mandibular growth in both groups. At the age of 9 years, all the angular measurement revealed statistical significance with SNA (P = 0.02), SNB (P = 0.05), ANB (P < 0.01), and SNPg (P = 0.05). CONCLUSIONS: The present study has shown that early anterior palate repair for 3-month-old cleft patients have better maxillary growth and less mandibular prognathism.

RESUMO

BACKGROUND: The objectives of this study were to investigate the treatment effect, morphology, and volumetric outcomes of monobloc frontofacial or Le Fort III distraction osteogenesis in syndromic craniosynostosis by 3-dimensional evaluation. MATERIALS AND METHODS: Nine consecutive patients underwent monobloc frontofacial or Le Fort III distraction during 2003 to 2012 were included and evaluated. The patient's evaluation is a minimum of a 4-year follow-up. Pretreatment, post-treatment advancement, and relapse were quantified. The changes in intracranial volume, upper airway volume, globe protrusion, advancement at bilateral malar eminence, and central face were calculated from computerized tomography before and after treatment. RESULTS: After distraction, the intracranial volume was increased by 16.4% in average, and the upper airway volume increased by 64.1%. Orbital protrusion improved by 9.9 mm in the left eye and 10.5 mm in the right eye in comparison to the preoperative status. Bilateral malar eminences advancement was greater than the dorsum advancement by 7.1 mm. CONCLUSION: The external distraction osteogenesis device caused significant technical difficulties with advancement of the midface in growing bones. The central midface did not advance as hoped for. This finding may suggest a need for modification in the distraction device in order to improve the central facial distraction vector.

RESUMO

OBJECTIVE: Vomer flap repair is assumed to improve maxillary growth because of reduced scarring in growth-sensitive areas of the palate. Our aim was to evaluate whether facial growth in patients with unilateral cleft lip and palate was significantly affected by the technique of hard palate repair (vomer flap versus two-flap). MATERIALS AND METHODS: For this retrospective longitudinal study, we analyzed 334 cephalometric radiographs from 95 patients with nonsyndromic complete unilateral cleft lip and palate who underwent hard palate repair by two different techniques (vomer flap versus two-flap). Clinical notes were reviewed to record treatment histories. Cephalometry was used to determine facial morphology and growth rate. The associations among facial morphology at age 20, facial growth rate, and technique of hard palate repair were assessed using generalized estimating equation analysis. RESULTS: The hard palate repair technique significantly influenced protrusion of the maxilla (SNA: ß = -3.5°, 95 % CI = -5.2-1.7; p = 0.001) and the anteroposterior jaw relation (ANB: ß = -4.2°, 95 % CI = -6.4-1.9; p = 0.001; Wits: ß = -5.7 mm, 95 % CI = -9.6-1.2; p = 0.01) at age 20, and their growth rates (SNA p = 0.001, ANB p < 0.01, and Wits p = 0.02). CONCLUSIONS: The results suggest that in patients with unilateral cleft lip and palate, vomer flap repair has a smaller adverse effect than two-flap on growth of the maxilla. This effect on maxillary growth is on the anteroposterior development of the alveolar maxilla and is progressive with age. We now perform hard palate closure with vomer flap followed by soft palate closure using Furlow palatoplasty. CLINICAL RELEVANCE: These findings may improve treatment outcome by modifying the treatment protocol for patients with unilateral cleft lip and palate.

RESUMO

BACKGROUND: Although several studies have reported the advantages of the surgery-first approach for orthognathic correction of class III deformity, there is no report of the success of this approach for patients with cleft lip and palate. Therefore, the purpose of this study was to evaluate the stability and outcome of bimaxillary surgery for cleft-related dentofacial deformity using a surgery-first approach. METHODS: Forty-one patients with unilateral cleft lip and palate who consecutively underwent Le Fort I and bilateral sagittal split osteotomies for skeletal class III deformity were included. Cone-beam computed tomographic scans before surgery, 1 week after surgery, and after orthodontic treatment were used to measure the surgical and postsurgical changes in jaw position by landmarks, and outcomes of jaw protrusion and relation, incisor angle and occlusion, and menton deviation after treatment. Self-report questionnaires regarding satisfaction with overall appearance of the face and seven facial regions were administered after treatment. RESULTS: A clinically insignificant relapse was found in the maxilla (<1 mm) and mandible (<2 mm). There was a significant improvement in the jaw protrusion and relation, incisor angle and occlusion, and menton deviation. Responses from the self-report questionnaires completed after treatment indicated that patient satisfaction was high. CONCLUSION: These findings demonstrate surgical-orthodontic treatment with a surgery-first approach can successfully improve cleft-related dentofacial deformity in patients with unilateral cleft lip and palate. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.

RESUMO

INTRODUCTION: Congenitally missing permanent teeth are common in patients with clefts. This retrospective study was conducted to evaluate the craniofacial characteristics in patients with unilateral complete cleft lip and palate with congenitally missing permanent teeth. METHODS: A series of 73 consecutive patients with nonsyndromic unilateral complete cleft lip and palate were enrolled. Evaluation of congenitally missing permanent teeth was based on the panoramic films taken from 7 to 11 years of age. The cephalometric films taken around 9 years of age were used to compare the craniofacial morphology in patients with no congenitally missing permanent teeth (n = 20) and 1 (n = 25), 2 (n = 18), and 3 (n = 10) congenitally missing permanent teeth. The Spearman correlation coefficient was used to assess the association of increased numbers of congenitally missing permanent teeth with each cephalometric parameter. RESULTS: Anterior facial height, distance from the maxillary incisor and first molar to the palatal plane, and overjet decreased as the number of congenitally missing permanent teeth increased in patients with unilateral cleft lip and palate. CONCLUSIONS: Unilateral cleft lip and palate patients with congenitally missing permanent teeth have a unique craniofacial morphology with a reduced vertical dimension.

RESUMO

BACKGROUND: Nasoalveolar molding (NAM) has become standard treatment in the authors' craniofacial center. There are two types of presurgical NAM: the Grayson and Figueroa techniques. The Grayson method involves active alveolar molding, and the Figueroa method involves passive alveolar molding. The authors previously found no differences in number of clinic visits, costs, or 6-month postoperative outcome between the two techniques. The authors extended the previous study to evaluate facial growth between these two groups. METHODS: In this randomized single-blind study, conducted between May of 2010 and March of 2013, the authors recruited 30 patients with unilateral complete cleft lip and palate and randomized them for Grayson or Figueroa presurgical NAM. Standard lateral cephalometric measurements at 5 years were used to determine facial growth. RESULTS: Twenty-nine patients completed 5 years of follow-up. There were no statistically significant differences in facial cephalometric measurements between the two groups. CONCLUSION: Presurgical NAM using either a passive or active NAM technique produced similar facial growth patterns after unilateral cleft lip and palate repair. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, II.

RESUMO

OBJECTIVE: To assess the results of maxillary distraction osteogenesis with the Rigid External Distraction System using three-dimensional computed tomography scan volume-rendered images with respect to stability and facial growth at three time frames: preoperative (T0), 1-year postoperative (T1), and 5-years postoperative (T2). DESIGN: Retrospective analysis. SETTING: Tertiary. PATIENTS: A total of 12 patients with severe cleft maxillary hypoplasia were treated between June 30, 1997, and July 15, 1998. The mean age at surgery was 11 years 1 month. INTERVENTIONS: Le Fort I maxillary distraction osteogenesis. Distraction was started 2 to 5 days postsurgery at a rate of 1 mm per day. The consolidation period was 3 months. No face mask was used. A paired t test was used for statistical analysis. MAIN OUTCOME MEASURES: Overjet, ANB, and SNA and maxillary, pterygoid, and mandibular volumes. RESULTS: From T0 to T1, there were statistically significant increments of overjet, ANB, and SNA and maxillary, pterygoid, and mandibular volumes. The T1 to T2 period demonstrated a reduction of overjet (30.07%) and ANB (54.42%). The maxilla showed a stable SNA and a small but statistically significant advancement of the ANS point. There was a significant increase in the mandibular volume. However, there was no significant change in the maxillary and pterygoid volumes. CONCLUSIONS: Maxillary distraction osteogenesis demonstrated linear and volumetric maxillary growth during the distraction phase without clinically significant continued growth thereafter. Overcorrection is required to take into account recurrence of midface retrusion over the long term.

RESUMO

INTRODUCTION: Initial cleft severity in patients with complete unilateral cleft lip and palate (UCLP) varies. This is reflected in the sizes of the cleft and the palate. The purpose of this retrospective study was to establish whether there is a relationship between cleft severity at birth and growth of the maxilla. METHODS: Maxillary dental casts of 29 infants with nonsyndromic complete UCLP were used to measure the sizes of the cleft and the palate. The later growth of the maxilla was determined by using cephalometric radiographs taken at age 9. Statistical analyses were performed with multiple linear regression. RESULTS: The results showed a relationship between cleft area and maxillary protrusion (SNA, P <0.05). Also, there was a relationship between palate area and maxillary width (P <0.05). CONCLUSIONS: These data suggest that in patients with complete UCLP there is a significant relationship between initial cleft severity and maxillary growth. Patients with a small cleft area have a more protruded maxilla than do those with a large cleft area. Patients with a large palate area have a wider maxilla than those with a small palate area.

RESUMO

OBJECTIVE: Gingivoperiosteoplasty performed at the time of lip repair of cleft patients is one kind of alveolar repair. The purpose of this retrospective study was to evaluate the effect of gingivoperiosteoplasty on facial growth of patients with complete unilateral cleft lip and palate (UCLP). DESIGN: Retrospective study. PATIENTS: Sixty-two consecutive patients with nonsyndromic complete unilateral cleft lip/palate with 5-year-olds' record were included in this retrospective study. INTERVENTIONS: All the patients had received nasoalveolar molding treatment before cheiloplasty at the age of 3 to 6 months. Twenty-six patients had gingivoperiosteoplasty performed at the time of cheiloplasty and function as the GPP group. Thirty-six patients did not have gingivoperiosteoplasty at the time of cheiloplasty and function as the non-GPP group. MAIN OUTCOME MEASURES: Cephalometry was used to evaluate the facial growth at 5 years of age in the two groups of patients. RESULTS: Gingivoperiosteoplasty had significant effects on the maxillary position (SNA), intermaxillary position (ANB), maxillary length (PMP-ANS), and maxillary alveolar length (PMP-A) at the age of 5 years. The SNA and ANB angles were larger in non-GPP group than in the GPP group by 3.0 degrees and 2.6 degrees , respectively. The maxillary length (PMP-ANS) and maxillary alveolar length (PMP-A) were larger in the non-GPP group than in the GPP group by 2.1 and 2.9 mm, respectively. CONCLUSIONS: In patients with UCLP, the sagittal growth of the maxilla would be affected more adversely in the GPP group than in the non-GPP group at the age of 5 years.

RESUMO

Secondary alveolar bone grafting (SABG) is associated with donor site morbidities. We aimed to compare the outcomes of SABG and extensive gingivoperiosteoplasty (EGPP) at the mixed dentition stage. This single-blinded, randomized, prospective trial enrolled 50 consecutive patients with unilateral complete cleft lip and palate who had residual alveolar bone cleft, of which 44 (19 SABG, 25 EGPP) completed the study. Bone volumes before surgery, 6 months postoperatively, and 1-year postoperatively were compared using computed tomography. The Bergland scale score was recorded at 6 months postoperatively. Both groups had the same preoperative alveolar cleft volume. On the Bergland scale, 21, 3, and 1 patient in the EGPP group and 16, 2, and 1 patient in the SABG group were classified as types I, II, and IV, respectively, which did not show significant difference. With perioperative orthodontic treatment, the 1-year residual bone defect volume in both groups did not show significant difference (SABG 0.12 cm3 vs. EGPP at 0.14 cm3, p > 0.05). The study was not able to reveal much difference between SABG and EGPP combined with perioperative orthodontic treatment.

RESUMO

Computer applications in head and neck reconstruction are rapidly emerging and create not only a virtual environment for presurgical planning, but also help in image-guided navigational surgery. This study evaluates the use of prefabricated 3-dimensional (3D) mirror image templates made by computer-simulated adjusted occlusions to assist in microvascular prefabricated flap insertion during reconstructive surgery. Five patients underwent tumor ablation surgery in 1999 and survived for 8 years. Four of the patients with malignancy received radiation therapy. All patients in this study suffered from severe malocclusion causing trismus, headache, temporomandibular joint pain, an unsymmetrical face, and the inability of further osseointegrated teeth insertion. They underwent a 3D computer tomography examination and the nonprocessed raw data were sent for computer simulation in adjusting occlusion; thus, a mirror image template could be fabricated for microsurgical flap guidance. The computer simulated occlusion was acceptable and facial symmetry obtained. The use of the template resulted in a shorter operation time and recovery was as expected. The computer-simulated occlusion-adjusted 3D mirror image templates aid in the use of free vascularized bone flaps for restoring continuity to the mandible. The coordinated arch will help with further osseointegration teeth insertion.

RESUMO

Asymmetric velopharyngeal incompetence (VPI) has a diverse etiology, but those without any underlying cleft, hemifacial microsomia (HFM), or facial asymmetry are rarely encountered. Such cases have been reported within the last few years, with unilateral velopharyngeal hypoplasia identified to be the underlying abnormality in these patients. However, there have been no reports to date on asymmetric VPI from idiopathic hemipalatal hypoplasia. A retrospective review of patients whose conditions were diagnosed with asymmetric VPI owing to hemipalatal hypoplasia and who do not have underlying cleft, HFM, or any significant facial asymmetry was performed. During a 10-year period, 5 patients with asymmetric VPI from idiopathic hemipalatal hypoplasia were treated at our center. Four of 5 of these patients presented with nasal regurgitation. Two were found to have tonsillar enlargement on the side of the hemipalatal hypoplasia, and another had an ipsilateral tongue mass that subsequently required wedge excision. Two were managed conservatively with speech therapy, whereas the other 3 developed speech problems that required surgery. The first patient underwent a skewed pharyngeal flap, but her speech problem improved only after a second surgery, which involved a centralized pharyngeal flap. The speech problems of the last 2 patients were corrected with a centralized pharyngeal flap. Hence, we conclude that patients with asymmetric VPI from idiopathic hemipalatal hypoplasia, compared with those of other etiology, particularly unilateral velopharyngeal hypoplasia, seem to present in a different manner. When surgical intervention is indicated for correction of the speech problem that eventually develops, centralized rather than skewed pharyngeal flap seems to be more reliable.

RESUMO

PURPOSE OF REVIEW: To give an update on recent publications and tendencies concerning complications in cleft orthognathic surgery. RECENT FINDINGS: Cleft-specific changes after orthognathic surgery and their impact on surgical outcomes are discussed. Focus lays on the causes and mechanisms of cleft-related surgical complications and strategies to prevent or minimize these complications. Bimaxillary surgery is seen as a safe procedure for cleft patients. Maxillary distraction, total or segmental, is pointed out as an alternative method to improve outcomes. Different techniques for osteotomies and maxillary mobilization could decrease adverse events. SUMMARY: Cleft patients are more susceptible to the occurrence of complications because of peculiar presurgical conditions. Different surgical approaches and techniques are presented to overcome these difficulties, to achieve better results and to increase patient safety. The importance of communication between patient, family and cleft team members is emphasized.

RESUMO

Upper lip scars are at risk of hypertrophy. Our center therefore uses microporous tape and silicone sheeting for postoperative scar care following cleft lip repair. However, some babies have previously ingested their silicone sheeting, which has the potential for respiratory compromise or gastrointestinal obstruction. Self-dry silicone gel is reportedly also effective for preventing hypertrophic scars. Hence, we sought to test whether silicone gel, which cannot be ingested whole, might be non-inferior to silicone sheeting for controlling against upper lip scar hypertrophy. This was a mixed prospective and retrospective case-controlled clinical trial involving patients undergoing unilateral cleft lip repair, 29 of whom received standard postoperative silicone sheeting (control group) and another 33 age-matched consecutive patients who received self-dry silicone instead. The Vancouver scar scale, visual analogue scale and photographically assessed scar width assessments were the same in both groups at six months after surgery. In conclusion, silicone gel appears to be non-inferior to silicone sheeting for postoperative care of upper lip scars as judged by scar quality at six months, but silicone sheeting has the safety disadvantage that it can be swallowed whole by babies. It is thus recommended that silicone gel be used for upper lip scar management in babies.

RESUMO

European and Northern American healthcare authorities increasingly encourage the use of Patient Reported Outcome Measures (PROMs) that complement clinical and laboratory assessments to help holistically evaluate reconstructive outcomes. This is the first study to evaluate PROMs in cleft lip/palate patients who have, or have not, undergone secondary alveolar bone grafting (SABG).A PROMs study was conducted; 40 consecutive consenting cleft lip/palate children between 8 and 14 years old were included. Twenty patients did, and 20 patients did not, have SABG. PROMs scores from children and parents in the 2 groups were compared.Forty patients completed the trial. No significant differences in total score from the Chang Gung Short Form-15 (CGSF-15) were found between children and their parents. Children with SABG reported no more oral-nasal regurgitation than children without SABG, but tended to report more nasal obstruction. There were no statistically significant differences in parent reported outcomes between the 2 groups.Cleft lip/palate patients who underwent SABG reported significantly less nasal regurgitation and more nasal obstruction compared to those patients who did not undergo SABG.

RESUMO

BACKGROUND: Most patients treated with orthognathic surgery for facial asymmetry would value improvement in residual soft-tissue asymmetry. Autologous fat transfer is widely used to augment facial soft tissue. The authors assessed the effect of combining orthognathic surgery with autologous fat transfer for treating patients with facial asymmetry. METHODS: In this retrospective study, 15 consecutive adults underwent combined orthognathic surgery and autologous fat transfer between January of 2013 and December of 2015. Lower facial profile symmetry was assessed using postoperative standard frontal photographs. RESULTS: Lower facial symmetry was much improved by combining orthognathic surgery and autologous fat injection. CONCLUSION: The combined use of orthognathic surgery and autologous fat transfer is a promising technique for improving facial symmetry in patients with facial asymmetry. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.
