Abstract
OBJECTIVE An inspiring early result with no oronasal fistula formation was recently described for a modified medial incision small double-opposing Z-plasty (MIsDOZ) for treating Veau type I cleft palate. This study describes an early single-surgeon experience in applying this newly proposed surgical approach. DESIGN Retrospective single-surgeon study. PATIENTS Consecutive nonsyndromic patients (n = 27) with Veau I cleft palate. INTERVENTIONS Topographic anatomical-guided MIsDOZ palatoplasty with pyramidal space dissection (releasing of the ligamentous fibers in the greater palatine neurovascular bundle and pyramidal process region, in-fracture of the pterygoid hamulus, and widening of space of Ernst) performed by a novice surgeon (RD). MEAN OUTCOME MEASURES Age at surgery, the presence of cleft lip, palatal cleft width, use of lateral relaxing incision, and 6-month complication rate (bleeding, dehiscence, fistula, and flap necrosis). A published senior surgeon-based outcome dataset (n = 24) was retrieved for comparison purposes. RESULTS Twenty-two (81.5%) and 5 (18.5%) patients received the medial incision only technique and lateral incision technique, respectively (P = .002). Age, presence of cleft lip, and cleft width were not associated (all P > .05) with the use of lateral incision. Comparative analysis between the novice surgeon- and senior surgeon-based datasets revealed no significant differences for sex (females: 74.1% vs 62.5%; P = .546), age (10.2 ± 1.7 vs 9.6 ± 1.2 months; P = .143), rate of lateral incision (18.5% vs 4.2%; P = .195), and postoperative complication rate (0% vs 0%). CONCLUSION This modified DOZ palatoplasty proved to be a reproducible procedure for Veau I cleft palate closure, with reduced need for lateral incision and with no early complication.

Abstract
Pedicled buccal fat flaps have been adopted in primary Furlow double-opposing Z-plasty palatoplasty to reduce oronasal fistula formation or to attenuate maxillary growth disturbance. We combined both goals in a single intervention. This study describes a series of 33 modified Furlow small double-opposing Z-plasty palatoplasties reinforced with a middle layer of pedicled buccal fat flaps between the oral and nasal layers for full coverage of the dissected palatal surfaces, with rapid mucosalization of lateral relaxing incisions and no dehiscence or fistula formation.

Abstract
BACKGROUND No consensus exists regarding the timing or technique of rhinoplasty for correction of the unilateral cleft lip nose deformity, with few studies examining the long-term effects of a single technique. This study appraised the long-term outcomes of primary rhinoplasty using the Tajima technique for overcorrection in a cohort of patients with unilateral cleft lip nose deformity after attaining skeletal maturity. METHODS Consecutive nonsyndromic patients with unilateral cleft lip nose deformity ( n = 103) who underwent primary rhinoplasty with overcorrection by a single surgeon between 2000 and 2005 were reviewed. Patients with unilateral cleft lip and nasal deformity who underwent primary rhinoplasty (but with no overcorrection) ( n = 30) and noncleft individuals ( n = 27) were recruited for comparison. Outcomes were assessed through FACE-Q scales evaluating satisfaction with appearance of nose and nostrils (two scales) and computer-based objective photogrammetric analysis of nasal symmetry (nostril height, nostril width, nostril area, alar height, and alar width parameters). RESULTS Significant differences (all P < 0.001) were observed between the Tajima and non-Tajima groups for all but one photogrammetric nasal parameter (nostril area), with the Tajima group demonstrating closer mean values to the noncleft group. The Tajima and noncleft groups demonstrated no significant difference (all P > 0.05) for scores of FACE-Q nose and nostrils scales. CONCLUSION This study indicated that the patients who underwent primary rhinoplasty with overcorrection had improved results with no necessity for intermediate rhinoplasty, emphasizing that the procedure is an effective approach to correct the unilateral cleft nose deformity. CLINICAL QUESTION/LEVEL OF EVIDENCE Therapeutic, III.

Abstract
BACKGROUND The pedicled buccal fat flap has recently been applied to cover the lateral raw surfaces during palatoplasty as an attempt to mitigate scar-induced transverse maxillary constriction during growth, but with no formal long-term comparative analysis. This 3D imaging-assisted study assessed its impact on posterior transverse maxillary development. METHODS Cone beam computerized tomography scans from patients with unilateral cleft lip, alveolus and palate who received buccal fat flap (buccal fat group; n=22) or Surgicel (Surgicel group; n=32) for covering lateral raw surfaces during modified Furlow palatoplasty at 9-10 months old and had reached 9 years old were retrieved for analysis. Patients with unilateral cleft lip and alveolus (non-palatoplasty group; n=24) were also included for comparison. Using 3D maxillary image models, linear (U6T-MSP and U6J-MSP) and area measurements were calculated for cleft and non-cleft posterior maxillary sides as well as for total posterior transverse maxillary dimension. RESULTS The buccal fat group had significantly (all p<0.05) wider dimensions compared with the Surgicel group for all transverse maxillary measurements on both the cleft and non-cleft sides, with exception for U6J-MSP and posterior palatal area parameters on the cleft side (p>0.05). The buccal fat group had significantly (all p<0.05) wider total transverse maxillary dimensions compared with Surgicel and non-palatoplasty groups. CONCLUSION Covering the lateral raw surfaces with buccal fat flaps resulted in less posterior transverse maxillary constriction compared with the Surgicel-based covering procedure.

Abstract
SUMMARY Secondary alveolar bone grafting is one of the key surgical procedures performed to restore dental arch continuity and facilitate tooth eruption in patients with cleft lip and palate. Harvest of cancellous bone graft from the iliac crest has become the gold standard; however. there is no consensus regarding the ideal technique. An optimal bone harvest technique must be aimed at producing minimal donor-site morbidity and patient discomfort. The success of the bone grafting procedure depends largely on the surgical technique. To restore cleft alveolar defects, one must be able to conceptualize the different underlying aspects of the problem to perform an effective surgical repair. It is important for surgeons-in-service to adopt newer techniques that significantly enhance the overall outcome. This article describes two techniques of iliac bone harvest and the principles involved in execution of the alveolar bone grafting procedure. The accompanying four-part video series depicts the bone harvest, flap design, dissection of the recipient cleft alveolus, and bone grafting in a step-by-step manner.

Abstract
Objective: In this study, we aim to present a single institution’s 25-year experience of employing a comprehensive multidisciplinary team-based surgical approach for treating patients with NF-1. Summary Background Data: All patients (n = 106) with a confirmed diagnosis of NF-1 who were treated using a multidisciplinary surgical treatment algorithm at Chang Gung Memorial Hospital between 1994 and 2019 were retrospectively enrolled. Patients were categorized into groups according to the anatomy involved (craniofacial and noncraniofacial groups) and the type of clinical presentation (plexiform and cutaneous neurofibromas groups) for comparative analysis. Methods: The number of surgical interventions and number of specialists involved in surgical care were assessed. Results: Most of the patients exhibited craniofacial involvement (69.8%) and a plexiform type of NF-1 (58.5%), as confirmed through histology. A total of 332 surgical interventions (3.1 ± 3.1 procedures per patient) were performed. The number of specialists involved in surgical care of the included patients was 11 (1.6 ± 0.8 specialists per patient). Most of the patients (62.3%) underwent two or more surgical interventions, and 40.6% of the patients received treatment from two or more specialists. No significant differences were observed between the craniofacial and noncraniofacial groups in terms of the average number of surgical interventions (3.3 ± 3.2 vs. 2.7 ± 2.7, respectively) and number of specialists involved (1.7 ± 0.9 vs. 1.4 ± 0.6). Patients with plexiform craniofacial involvement underwent a significantly higher average number of surgical interventions (4.3 ± 3.6 vs. 1.6 ± 1.1; p < 0.001) and received treatment by more specialists (1.9 ± 0.9 vs. 1.2 ± 0.5; p < 0.001) compared with those having cutaneous craniofacial involvement. Conclusions: In light of the potential benefits of employing the multidisciplinary team-based surgical approach demonstrated in this study, such an approach should be adopted to provide comprehensive individualized care to patients with NF-1.

Abstract
SUMMARY Encouraging results have been described for the use of pedicled buccal fat pad flap in primary cleft palate repair. This retrospective study describes the surgical technique and early results of a technical innovation utilizing the split buccal fat flaps in modified Furlow palatoplasty with small double-opposing Z-plasty. This technique introduces buccal fat tissue for coverage of lateral denuded palate surfaces to reduce the bone exposure and scar formation to potentially attenuate maxillary growth interference and for reinforcement of the palatal areas of high tension or with incomplete closure to decrease the risk of postoperative dehiscence and oronasal fistula formation. Consecutive nonsyndromic patients (n = 56) with cleft palate were treated with this method, all of whom demonstrated fast mucosalization of lateral palatal recipient regions within 3 weeks postoperatively and showed no fistula with 12 months' follow-up. Of 19 patients (33.9 percent) who underwent auditory-perceptual assessment, 15 (78.9 percent) had normal resonance. Surgeons could add this alternative surgical maneuver to their armamentarium during the primary palatoplasty, in which coverage of lateral surfaces and reinforcement with fat tissue in the anterior soft palate space are of paramount relevance.

Abstract
SUMMARY Patients with maxillomandibular disharmony may present with a flat to concave midface. The effects of orthognathic surgery concomitant with midface fat grafting on facial appearance and midface volumetric and positional change have not formally been assessed to date. The authors' approach for synchronous orthognathic surgery and fat grafting is described and evaluated. Adult female patients (n = 20) who underwent synchronous two-jaw orthognathic surgery and cheek-specific fat grafting (1.9 ± 0.6 cm3 per side) for correction of skeletal class III deformity and anteromedial cheek deficiency were prospectively included. Preoperative and postoperative photographs were appraised by 42 blinded raters using facial appearance scales for beauty, attractiveness, and pleasantness parameters. The three-dimensional midface soft-tissue volume change and postoperative cheek mass position were computed. Facial imaging data from gender-, ethnic-, and facial pattern-matched adult patients (n = 20) who underwent isolated two-jaw orthognathic surgery (n = 20) were included for comparison. The three-dimensional facial norms database-derived cheek mass position information (2.19 ± 1.31mm) was also adopted for analysis. Patients treated with the synchronous procedure had significantly (p < 0.001) increased facial appearance-related perception change for beauty (2.9 ± 1.6), attractiveness (2.8 ± 1.8), and pleasantness (3.0 ± 1.5) parameters, three-dimensional midface volume change (1.8 ± 0.5 cm3), and postoperative cheek mass position (2.16 ± 0.47 mm) in comparison with those treated with the isolated procedure (2.0 ± 1.5, 1.9 ± 1.6, 2.3 ± 1.6, 0.6 ± 0.2 cm3, and 1.84 ± 0.43 mm, respectively). Healthy female individuals had similar and larger cheek mass position than patients treated with synchronous (p > 0.05) and isolated (p < 0.001) procedures, respectively. Synchronous orthognathic surgery and check-specific fat grafting resulted in superior enhancement of facial appearance and midface volume and position compared with isolated orthognathic surgery.

Abstract
BACKGROUND Craniofrontonasal dysplasia (CFND) is a rare congenital craniofacial syndrome characterized by single suture synostosis, hypertelorism, other clinical facial features, and abnormalities in the upper extremities. There are only a few studies in the applicable literature that address hypertelorism management for CFND patients and outcomes and complication rates. METHODS A retrospective study was performed on consecutive late presenting CFND patients referred to our hospital with substantially completed craniofacial skeleton growth, who underwent hypertelorism correction between 2007 and 2019 following intracranial pressure screening, and who received at least 1 year of follow-up care. None of the patients in this study underwent prior craniofacial surgery. Only those patients with a confirmed mutation of the EFNB1 gene were included in this study. All patients in this study underwent hypertelorism correction by facial bipartition or box osteotomy. RESULTS A total of ten late presenting CFND patients (all female) were treated at our hospital during the study period. None of the patients presented signs of elevated intracranial pressure. The average patient age at hypertelorism correction was 13.4 ± 7.68 years of age. Major complications, defined as complications requiring a return to the operating room, were limited to infection of the frontal bone, which required partial bone removal, and cerebrospinal fluid (CSF) leak, which was completely resolved by insertion of a lumbar shunt for a 7-day period. CONCLUSION The absence of elevated intracranial pressure enables hypertelorism correction in late presenting CFND patients via facial bipartition or box osteotomy without the need for additional operations that provide for cranial expansion.

Abstract
SUMMARY Millard's rotation-advancement principle, first-described 60 years ago, continues to guide surgeons in reconstruction of the unilateral cleft lip. Modifications of the rotation-advancement repair are commonly used; however, distinction between the complete and incomplete forms of cleft lip has received less emphasis in surgical procedure descriptions. As a unilateral incomplete cleft lip could present with more tissue overall and a larger lip on the cleft side than a complete form of cleft lip, the authors have adopted a deformity-specific technical approach to treat each particular cleft form. This article highlights the 10 key steps for execution of a modified unilateral incomplete cleft lip repair using the rotation-advancement principle plus the "skin-follows-muscle" model. The intraoperative design and the reconstruction of the skin, muscle, vermilion, intraoral mucosal, and nasal elements are fully detailed in the accompanying videos.

Abstract
Crouzon syndrome is a rare form of syndromic craniosynostosis (SC) characterized by premature fusion of the cranial and facial sutures, elevated intracranial pressure, varying degrees of ocular exposure due to exorbitism, and airway compromise caused by midface retrusion. Craniolacunae and upper and lower extremity anomalies are not frequently found in Crouzon syndrome. We present a girl with Crouzon syndrome caused by c.1040 C > G, p.Ser347Cys, a pathogenic mutation in the FGFR2 gene with atypical characteristics, including craniolacunae resembling severe Swiss cheese type of bone formation, and upper and lower extremity anomalies which are more commonly associated with Pfeiffer syndrome patients. Distinguishing between severe Crouzon syndrome patients and patients who have mild and/or moderate Pfeiffer syndrome can be challenging even for an experienced craniofacial surgeon. An accurate genotype diagnosis is essential to distinguishing between these syndromes, as it provides predictors for neurosurgical complications and facilitates appropriate family counseling related to long-term outcomes.

Abstract
BACKGROUND Hand reconstruction for patients with Apert syndrome is a critical step in comprehensive care and enables this population to gain significant hand function. Digit separation for Apert syndrome, as described in most algorithms, is finalized using local flaps and full-thickness skin grafts. The objective of this study is to report our experience using local flaps and partial-thickness skin grafts after digit separation for Apert hand reconstruction. METHODS An observational retrospective study was performed with Apert patients whose hands were reconstructed between January 2007 and July 2019 using local flaps and partial-thickness skin grafts after digit separation. Demographic data and outcome data were verified and recorded. RESULTS Out of a total of 75 Apert patients who underwent hand reconstruction, 12 underwent hand reconstruction utilizing local flaps and partial-thickness skin grafts. The average patient age at the time of the first procedure was 1.9 years. These 12 patients were stratified according to Upton hand severity, 3 being type I (25%), 3 being type II (25%) and 6 being type III (50%). Mean follow up provided to all patients in this study was 1.8 years and donor site-related complications were seen in 2 patients (16.6%). No flexion scar contracture was observed in any of the patients who received partial-thickness skin grafts. CONCLUSIONS The use of local flaps along with partial-thickness skin grafts to finalize digit separation for patients with Apert syndrome is an effective technique that reduces donor site morbidity and does not result in flexion scar contracture.

Abstract
BACKGROUND The CLEFT-Q includes 12 independently functioning scales that measure appearance (face, nose, nostrils, teeth, lips, jaws), health-related quality of life (psychological, social, school, speech distress), and speech function, and an eating/drinking checklist. Previous qualitative research revealed that the CLEFT-Q has content validity in noncleft craniofacial conditions. This study aimed to examine the psychometric performance of the CLEFT-Q in an international sample of patients with a broad range of facial conditions. METHODS Data were collected between October 2016 and December 2019 from 2132 patients aged 8 to 29 years with noncleft facial conditions. Rasch measurement theory (RMT) analysis was used to examine Differential Item Function (DIF) by comparing the original CLEFT-Q sample and the new FACE-Q craniofacial sample. Reliability and validity of the scales in a combined cleft and craniofacial sample (n=4743) were examined. RESULTS DIF was found for 23 CLEFT-Q items when the datasets for the two samples were compared. When items with DIF were split by sample, correlations between the original and split person locations showed that DIF had negligible impact on scale scoring (correlations ≥0.995). In the combined sample, RMT analysis led to the retention of original content for ten CLEFT-Q scales, modification of the Teeth scale, and the addition of an Eating/Drinking scale. Data obtained fit with the Rasch model for 11 scales (exception School, p=0.04). Person Separation Index and Cronbach alpha values met the criteria. CONCLUSION The scales described in this study can be used to measure outcomes in children and young adults with cleft and noncleft craniofacial conditions.

Abstract
BACKGROUND/PURPOSE Studies have reported the advantages of digital imaging-assisted orthognathic surgery planning, but there is scarce information about a full digital planning modality. This study evaluated the 3D cephalometric-based and patient-reported outcomes of a full digital workflow for orthognathic surgery planning in the treatment of asymmetric maxillomandibular disharmony. METHODS A postoperative 3D image dataset of 30 Taiwanese Chinese patients with asymmetric skeletal Class III deformities who underwent full digital planning for two-jaw surgery were retrieved from the authors' database. The 3D cephalometric data (dental, skeletal, and soft tissue evaluations) were compared to the ethnicity-matched 3D cephalometric normative values. Patient-reported outcome measure tools regarding postoperative overall appearance and satisfaction with facial areas (ranging from 0 to 100 and 0 to 10, respectively) were administered. The number of needed or requested revisionary surgery was collected. RESULTS No difference (all p > 0.05) was observed between the orthognathic-surgery-treated patients and the normative value for most of the tested 3D cephalometric parameters, with the exception (p < 0.05) of three mandible and occlusal-plane-related parameters. Both patient-reported outcome measure tools showed that patients' satisfaction with their postoperative appearance was high for overall face (89.7 ± 4.5) and specific facial regions (nose, 7.1 ± 1.3; lip, 8.3 ± 1.6; upper gum, 8.5 ± 1.2; cheek, 8.8 ± 1.1; chin, 9.2 ± 1.2; and teeth, 9.3 ± 0.8), with no need for revisionary surgery. CONCLUSION The patients treated with a full 3D digital planning-assisted two-jaw surgery had a similar 3D dental relation, facial convexity, and symmetry compared to healthy ethnicity-matched individuals, and they reported higher satisfaction levels with their postoperative facial appearance results.

Abstract
PURPOSE The most commonly occurring syndromic craniosynostoses are Apert syndrome, Crouzon syndrome, Pfeiffer syndrome, and Saethre-Chotzen syndrome. There is insufficient data regarding postoperative syndrome-related outcomes following the posterior vault distraction osteogenesis (PVDO) procedure, as well as data addressing whether or not additional procedures will be subsequently necessary to comprehensively treat children who undergo PVDO. Thus, the objective of this study is to describe and compare syndrome-related potential complications and outcomes associated with the PVDO procedure. METHODS An observational retrospective study was performed on consecutive patients (n=24) with Apert syndrome, Crouzon syndrome, Pfeiffer syndrome, or Saethre-Chotzen syndrome, respectively, who underwent PVDO between 2012 and 2019. Demographic data (patient gender and age when the PVDO procedure was performed), diagnosis, surgery-related data, and outcome data (perioperative and midterm complications and need for additional surgery) were verified. RESULTS Total relative blood transfusion volumes per kilogram for the patients were as follows: 22.75 ± 9.30 ml for Apert syndrome, 10.73 ± 2.28 ml for Crouzon syndrome (Apert versus Crouzon, p<0.05), 18.53 ± 8.08 ml for Pfeiffer syndrome, and 19.74 ± 9.12 ml for Saethre-Chotzen syndrome. None of the patients required a secondary procedure to alleviate intracranial pressure except for a Saethre-Chotzen patient. CONCLUSION PVDO is an effective technique to address elevated intracranial pressure in SC patients that alleviates the need for secondary procedures at midterm follow-up. Apert syndrome patients presented relatively higher total blood transfusion rates than Crouzon syndrome patients who were operated on at a later age and weighed more.

Abstract
BACKGROUND The evolving 3-dimensional computer-based technology revolutionized the field of orthognathic surgery (OGS). Digital occlusion setup for OGS may provide advantages in the planning comparing with the conventional approach based on the manual setup using dental casts, but we are not aware of any study focusing on digital occlusion setup for cleft OGS. The purposes of this study were to compare the conventional and digital occlusion setup approaches and to propose a protocol for digital occlusion setup in unilateral cleft OGS. METHODS Thirty consecutive patients with unilateral cleft lip/palate who underwent orthodontic treatment by a single orthodontist and 2-jaw OGS by a single surgeon using 3-dimensional surgical simulation were adopted for analysis. Quantitative data were collected from the dental cast occlusion setup approach (conventional group). A multidisciplinary team combined this quantitative data and established a protocol for digital occlusion setup in cleft OGS. Digital occlusions were set according to this protocol using the images of the 30 patients, and quantitative data were collected accordingly (digital group). The results of 2 groups were compared. All information was reviewed to refine the protocol and define the final guidelines. RESULTS There were no significant differences (all P > 0.05) for all parameters, except midline discrepancy (conventional group > digital group, P < 0.001). The root-mean-square deviation (0.46 ± 0.26 mm) indicated acceptable relationship between the conventional and digital groups. A 6-step protocol for digital occlusion setup in cleft OGS was established: dental midline, overjet/overbite, yaw rotation, pitch rotation, roll rotation, and overall facial skeletal appearance. CONCLUSIONS This study shows that digital occlusion setup is quantitatively comparable with the conventional dental model approach and contributes for cleft OGS by establishing a protocol for surgical occlusion setup using digital approach.

Abstract
Monobloc and facial bipartition combined with distraction osteogenesis (MFBDO) has gained popularity over the past several years as a treatment of syndromic craniosynostosis, in part because this surgical technique effectively removes many stigmatic clinical features associated with the syndromic face. The objective of this study is to detail the surgical planning used to achieve medialization of the orbits and describe the authors' experience using MFBDO to destigmatize the syndromic face. By using MFBDO, hypertelorism, vertical orbital dystopia, and downslanting of the palpebral fissure were surgically corrected in all patients, thereby destigmatizing the syndromic face.

Abstract
BACKGROUND The Le Fort I maxillary advancement and rotational movement have been adopted to treat patients with cleft-related skeletal Class III pattern and anteromedial cheek soft tissue deficiency, but cleft-specific cheek soft tissue prediction data are insufficient. This 3D imaging-based study addressed the issue. METHODS 3D craniofacial soft tissue and bone models were created from 32 consecutive patients who received computer-aided two-jaw orthognathic surgery for the correction of cleft-related Class III deformity and cheek soft tissue deficiency. Using superimposed 3D models, the cheek volumetric change, the cheek sagittal movement, and the 3D cheek mass position were calculated. 3D data from orthognathic surgery-treated patients with no cleft (noncleft cohort) and individuals with no facial deformity (3D norm value) were retrieved for comparative analysis. RESULTS Surgical maxillary advancement (p < 0.001) but not maxillary clockwise rotation (p > 0.05) had a significant impact on the cheek soft tissue change, with prediction models showing that maxillary advancement elucidated 77 and 79% of this change on the cleft and noncleft sides, respectively. Cleft cohort (0.46±0.12) had a significantly (p < 0.001) smaller cheek soft-to-hard tissue ratio than that of the noncleft cohort (0.73±0.13). Cleft maxillary advancements >4 mm resulted in a 3D cheek mass position (2.1±1.1 mm) similar (p > 0.05) to the 3D norm value (2.2±1.2 mm), but different (p = 0.037) from the noncleft cohort (2.38±0.7 mm). CONCLUSION This study showed that maxillary advancement but not the maxillary rotation affects the cheek soft tissue change, and the predictive values and comparative data could assist the orthodontist-surgeon interaction during preoperative planning and patient counseling.

Abstract
BACKGROUND/PURPOSE Three-dimensional computer-assisted orthognathic surgery allows to simulate the space between the mandibular ramus segments, i.e. intersegmental gap, for the correction of facial asymmetry. The purposes of the study were to estimate the screws- and mandible bone-related changes from the early postoperative period to the period after the debonding and to measure the association between the intersegmental gap volume and the screws- and mandible bone-related changes. METHODS This cone-beam computed tomography (CBCT)-assisted retrospective study assessed the stability of the bicortical positional screw fixations in maintaining the space between the mandibular ramus segments after bilateral sagittal split osteotomy in correction of 31 patients with malocclusion and facial asymmetry. The primary predictor variable was the CBCT-based intersegmental gap volume at early postoperative period (T1). The primary outcome variables were CBCT-based screws- and bone-related measurement changes between the T1 and T2 (at debonding) periods. RESULTS No significant differences were observed in screws-related linear and angular measurements between T1 and T2 virtual models. Some of mandible bone-related linear and angular measurements had significant differences (P < 0.05) between the T1 and T2 images, but with no clinical repercussion such as need of revisionary surgery. The gap volume and the screws- and bone-related changes had no significant correlations. CONCLUSION This study contributes to the multidisciplinary-related literature by demonstrating that the bicortical positional screws-based fixation technique in maintaining the three-dimensional-simulated space between the mandibular ramus segments is a stable and clinically acceptable option for correction of facial asymmetry associated with malocclusion, regardless of intersegmental gap size.

Abstract
BACKGROUND The FACE-Q Craniofacial Module is a patient-reported outcome measure designed for patients aged 8 to 29 years with conditions associated with a facial difference. In part 1, we describe the psychometric findings for the original CLEFT-Q scales tested in patients with cleft and noncleft facial conditions. The aim of this study was to examine psychometric performance of new FACE-Q Craniofacial Module scales. METHODS Data were collected between December 2016 and December 2019 from patients aged 8 to 29 years with conditions associated with a visible or functional facial difference. Rasch measurement theory (RMT) analysis was used to examine psychometric properties of each scale. Scores were transformed from 0 (worst) to 100 (best) for tests of construct validity. RESULTS 1495 participants were recruited with a broad range of conditions (e.g., birthmarks, facial paralysis, craniosynostosis, craniofacial microsomia, etc.) RMT analysis resulted in the refinement of 7 appearance scales (Birthmark, Cheeks, Chin, Eyes, Forehead, Head Shape, Smile), two function scales (Breathing, Facial), and an Appearance Distress scale. Person separation index and Cronbach alpha values met criteria. Three checklists were also formed (Eye Function, and Eye and Face Adverse Effects). Significantly lower scores on eight of nine scales were reported by participants whose appearance or functional difference was rated as a major rather than minor or no difference. Higher appearance distress correlated with lower appearance scale scores. CONCLUSION The FACE-Q Craniofacial Module scales can be used to collect and compare patient reported outcomes data in children and young adults with a facial condition.

Abstract
ABSTRACT We present here the unique case of a patient with a Tessier 1-13 rare facial cleft accompanied by cleft lip and palate and Tessier grade 2 hypertelorism. The patient described in this article has a twin brother who shares a number of genetic traits and physical features but does not present facial cleft or hypertelorism. The 45-year follow-up in this case is believed to be the longest follow-up to date to have been reported in the literature, and sheds significant light on the importance of extended longitudinal follow-up to maximize patient outcomes.

Abstract
BACKGROUND Le Fort I maxillary repositioning influences nasal morphology. In Asian cultures, upward nasal tip rotation with increased nostril exposure is considered aesthetically unpleasant and can have psychosocial consequences. This three-dimensional imaging-based study evaluated the effect of different Le Fort I maxillary movements on nasal tip rotation. METHODS Consecutive patients who underwent two-jaw orthognathic surgery (n = 107) were enrolled. To achieve a standard head orientation, preoperative and 1-week and 12-month postoperative cone-beam computed tomography-derived three-dimensional craniofacial models were superimposed. Tip rotation angle was calculated according to the Frankfort horizontal plane for all three-dimensional digital models. The final tip rotation angle change was defined as 12-month postoperative value minus preoperative value. Translational maxillary movement types (advancement versus setback and intrusion versus extrusion), postoperative maxillary segment locations (anterosuperior, anteroinferior, posterosuperior, or posteroinferior), and actual linear maxillary changes were noted. RESULTS Advancement (1.79 ± 5.20 degrees) and intrusion (2.23 ± 4.96 degrees) movements demonstrated significantly larger final tip rotation angle changes than setback (-0.88 ± 5.15 degrees) and extrusion (0.09 ± 5.44 degrees) movements (all p < 0.05). Postoperative anterosuperior location (2.95 ± 4.52 degrees) of the maxillary segment demonstrated a significantly larger final tip rotation angle change than anteroinferior (0.48 ± 5.65 degrees), posterosuperior (-1.08 ± 4.77 degrees), and posteroinferior (-0.64 ± 5.80 degrees) locations (all p < 0.05). Translational maxillary movement and actual linear maxillary change were not correlated with final tip rotation angle change. CONCLUSION Effects of Le Fort I maxillary repositioning on nasal tip rotation depend on movement types and maxillary segment location. CLINICAL QUESTION/LEVEL OF EVIDENCE Therapeutic, III.

Abstract
BACKGROUND The objective of this trial is to evaluate the flexibility of the cartilaginous component of the cleft nose after diced cartilage rhinoplasty by determining the degree of possible bending in relation to the vertical nasal dorsum axis and to compare with to a control group of the unaffected population. PATIENTS AND METHODS Fifteen cleft nose patients with diced cartilage rhinoplasty were included in this study, as well as a control group of 15 unaffected individuals. The angle of maximum nasal bending is measured between the basic and maximum bending axis and performed by the same rater twice at least 2 weeks apart to account for intrarater reliability. Study groups were compared with Fisher and independent t test. RESULTS The maximum bending to the left side was 16.10 ± 5.03 degrees for the study group and 23.95 ± 6.54 degrees for the control group (P = 0.001). The maximum bending to the right side were 16.54 ± 6.73 degrees for the study group and 23.00 ± 8.88 degrees for the control group (P = 0.034). CONCLUSION Diced cartilage graft injection for dorsal augmentation yields reproducible and esthetically pleasing outcomes with good flexibility and natural feel of the nasal tip. Although there is a significant difference compared with a nonaffected control group in maximum bending capacity, all patients in this study were satisfied with the results.

Abstract
BACKGROUND The surgical management of hypertelorism is challenging for plastic surgeons, and limited long-term outcome data are available. The purpose of this long-term study was to report a single-surgeon experience with a staged reconstructive protocol for hypertelorism correction. METHODS This retrospective study reviewed the records of patients with hypertelorism who were surgically managed by a single surgeon between 1978 and 2000. Bone (orbital box osteotomy and orthognathic surgery) and soft tissue (rhinoplasty and epicanthoplasty) surgeries were performed based on a patient-specific surgical protocol. Included patients were divided into a childhood group and an adolescence or adulthood group according to their age at orbital repositioning (≤12 and >12 years, respectively). Patients were invited for clinical interviews in February 2020 to evaluate whether requests for revision surgery had been made. The photogrammetric analysis-based hypertelorism index was calculated at preoperative and long-term postoperative times. Satisfaction with the long-term outcome was judged by both surgical professionals and laypeople. RESULTS In total, 14 patients with hypertelorism of different etiologies were included, with no request for revision surgery during an average follow-up of 29 years. The preoperative hypertelorism index was higher than the long-term postoperative evaluation (all, P < 0.05) for both childhood and adolescence or adulthood groups. Intergroup comparison revealed no significant difference for the hypertelorism index and panel assessment-based satisfaction with long-term outcome analysis (all, P > 0.05). CONCLUSIONS Considering the complexity and wide spectrum of clinical presentation of soft tissue and bone deformities in hypertelorism and current outcomes, the surgical approach to these patients should be staged and individualized for achievement of a balanced result between functional (orbital, occlusion, and psychosocial) and aesthetic parameters.

Abstract
BACKGROUND Le Fort I maxillary movements affect nasal width, but nasal width changes with specific movement types have not been formally addressed to date. OBJECTIVES The purpose of this study was to analyze and compare the changes in nasal width with different maxillary movements. METHODS A retrospective study was performed among consecutive patients who underwent bimaxillary orthognathic surgery (n = 138) and who were grouped based on the type of maxillary movement (ie, maxillary advancement with intrusion [MAI], maxillary advancement with extrusion [MAE], and maxillary setback with intrusion [MSI]). Preoperative and 12-month postoperative nasal widths were analyzed photogrammetrically by 2 blinded evaluators. RESULTS Maxillary advancement with intrusion and MAE presented a significantly (P < 0.05) higher alar base widening than MSI did, with no significant (P > 0.05) differences between MAI and MAE. Maxillary advancement movements (MAI and MAE) showed significantly (P < 0.05) higher alar base widening than maxillary setback movement (MSI). However, no significant (P > 0.05) difference was observed between maxillary intrusion (MAI and MSI) and maxillary extrusion (MAE) movements. CONCLUSIONS This study shows that the nasal width varies distinctly depending on the type of Le Fort I maxillary surgical movement.

Abstract
PURPOSE Three-dimensional (3D) computer-aided planning has truly revolutionized orthognathic surgery (OGS) treatment, but no study has compared the traditional hybrid and full 3D digital planning models. This study compared these virtual planning models in the treatment of asymmetric maxillomandibular disharmony. METHODS Young adult patients with an asymmetric skeletal class III deformity who underwent 3D computer-aided 2-jaw OGS using hybrid (alginate dental impression, 2D cephalometric tracings, manual-guided stone model surgery, occlusion setup, and splint fabrication; n = 30) or full digital (laser-scanned dentition, 3D cephalometric tracings, virtual-based occlusion setup and surgery, and computer-generated surgical splint; n = 30) planning models were consecutively recruited. Preoperative and postoperative 3D cephalometric analyses (dental relation, skeletal assessments based on sagittal and frontal views, and soft tissue evaluations) were adopted for intragroup and intergroup comparisons. Postoperative patient-perceived satisfaction with facial appearance was also recorded. RESULTS Both hybrid and full digital planning groups had significant (all P < 0.05) improvements after surgery with respect to facial convexity, incisor overjet, and frontal symmetry parameters. The full 3D digital planning-based OGS treatment had similar (all P > 0.05) 3D cephalometric-derived outcomes (preoperative, postoperative, and treatment-induced change data) and patient-perceived outcomes compared with the traditional hybrid 3D planning method. CONCLUSIONS For the decision-making process in selecting the planning model, multidisciplinary teams could consider additional parameters such as patient comfort, storage needs, convenience for data reuse, overall planning time, availability, and costs.

Abstract
Surgeons-in-training learning how to perform cleft surgery should not only acquire a broad repertoire of technical details but also master the proper execution of techniques based on the modern principles of bilateral cleft lip repair with synchronous reconstruction of cleft nose deformity. This article describes a bilateral complete cleft lip repair by adopting these principles, plus a modified composition of mucosal flaps for the nasal floor and intraoral linings, including the prolabial mucosal flap, C-flap mucosal flap, inferior turbinate mucosal flap, and lateral nasal mucosal flap. The accompanying four-part video series presents the step-by-step approach for design and execution of this alternative technique.

Abstract
BACKGROUND As the performance of late primary palatoplasty for skeletally mature patients remains controversial, there is little data available regarding speech outcomes for this patient population. The purpose of this study therefore is to identify and evaluate the impact of speech outcomes following late palate repair on skeletally mature patients. METHODS A retrospective study was performed on 19 consecutive skeletally mature patients who underwent late primary palate repair between 2010 and 2018. Speech assessment was performed preoperatively, between 3 and 6 months postoperatively, and then after 6 months postoperatively. Levels for hypernasality, oral pressure, and audible nasal air emission were scored and recorded.Patients were stratified by age, gender, presence of postoperative fistula, and Veau cleft type, in order to determine the impact of each variable on final speech outcomes. The Kruskal-Wallis test was used to compare the preoperative speech assessment with the postoperative speech outcomes, and the Mann-Whitney test was used to analyze the impact of the above variables on final speech outcomes. RESULTS Our data showed overall postoperative speech improvement for all tested variables. Patients without postoperative fistula presented better results in oral pressure than those patients with postoperative fistula (P < 0.05). None of the other tested variables presented a significant negative impact on speech outcomes. CONCLUSION Late primary palatoplasty significantly improves speech outcomes for skeletally mature patients. Fistula has a negative impact on oral pressure.

Abstract
BACKGROUND The purpose of this study was to assess the objective and subjective outcomes of lower face volumetric (contour) asymmetry correction with isolated fat grafting in skeletally immature patients. METHODS A prospective analysis was conducted of skeletally immature patients (n = 73) with craniofacial microsomia and Parry-Romberg syndrome who underwent isolated fat grafting (with no previous or concomitant bone surgery) using anatomical surgical principles (facial subunits and fat compartments) for the reconstruction of lower face volumetric asymmetry. Objective ultrasound and photogrammetric lower face symmetry analyses were blindly performed preoperatively and at 3 and 12 months postoperatively. A panel assessment of blinded surgical professionals and laypersons was also obtained to grade the subjective lower face symmetry. RESULTS There were significant (all P < 0.05) postoperative objective and subjective lower face symmetry enhancements (preoperative < postoperative) after isolated fat grafting, with no differences (all P > 0.05) between 3 versus 12 months' postoperative comparisons. CONCLUSIONS Growing patients with unilateral lower face volumetric asymmetries presented with improvement of objective and subjective symmetry after a single isolated fat grafting procedure.

Abstract
A scale with robust statistical validation is essential to diagnose pain and improve decision making for analgesia. This blind, randomised, prospective and opportunist study aimed to develop an ethogram to evaluate behaviour and validate a scale to assess acute ovine postoperative pain. Elective laparoscopy was performed in 48 healthy sheep, filmed at one preoperative and three postoperative moments, before and after rescue analgesia and 24 hours after. The videos were randomised and assessed twice by four evaluators, with a one-month interval between evaluations. Statistical analysis was performed using R software and differences were considered significant when p <0.05. Based on the multiple association, a unidimensional scale was adopted. The intra- and inter-observer reliability ranged from moderate to very good (intraclass correlation coefficient ≥ 0.53). The scale presented Spearman correlations > 0.80 with the numerical, simple descriptive, and visual analogue scales, and a correlation of 0.48 with the facial expression scale. According to the mixed linear model, the scale was responsive, due to the increase and decrease in pain scores of all items after surgery and analgesic intervention, respectively. All items on the scale demonstrated an acceptable Spearman item-total correlation (0.56-0.76), except for appetite (0.25). The internal consistency was excellent (Cronbach's α = 0.81) and all items presented specificity > 0.72 and sensitivity between 0.61-0.90, except for appetite. According to the Youden index, the cut-off point was ≥ 4 out of 12, with a diagnostic uncertainty zone of 4 to 5. The area under the curve > 0.95 demonstrated the excellent discriminatory capacity of the instrument. In conclusion, the Unesp-Botucatu pain scale in sheep submitted to laparoscopy is valid, reliable, specific, sensitive, with excellent internal consistency, accuracy, discriminatory capacity, and a defined cut-off point.

Abstract
BACKGROUND No consensus exists on the selection of procedures for the treatment of submucous cleft palate, with scarce reports on long-term outcomes from single-surgeon experience. This study assessed the outcomes of using extended indication criteria of Furlow palatoplasty as the first-line procedure for the management of submucous cleft palate-associated velopharyngeal insufficiency. METHODS Consecutive nonsyndromic patients with submucous cleft palate (n = 216) treated by a single surgeon between 1998 and 2018 were reviewed. Furlow palatoplasty was performed in all patients diagnosed with submucous cleft palate-associated velopharyngeal insufficiency, regardless of the age cutoff, number of Calnan triad features, or velopharyngeal gap size and pattern. Postoperative velopharyngeal function outcome (adequate, marginal, or inadequate) and the need for secondary surgery were investigated. Age at surgery, sex, submucous cleft palate type (classic and occult), and presence of complication were evaluated for potential associations with this outcome. RESULTS Forty-seven patients aged 8.3 ± 4.6 years with occult submucous cleft palate were significantly (p < 0.001) older than those with the classic type (n = 169; 5.6 ± 3.1 years). Most (p < 0.001) of the included patients [n = 181 (83.8 percent)] achieved adequate postoperative velopharyngeal function outcome. Three patients (1.4 percent) presented surgery-related complications, including bleeding and partial wound disruption. Secondary speech surgery was recommended in 24 patients (11.1 percent). In the bivariate and multivariate analyses, none of the tested variables was found to be associated (all p > 0.05) with the postoperative velopharyngeal function outcome. CONCLUSION The extended indication criteria of Furlow palatoplasty provided adequate velopharyngeal insufficiency management with a low complication rate and satisfactory speech outcome.

Abstract
BACKGROUND Surgical mobilization of the maxillary segment affects nasal morphology. This study assessed the impact of the type of maxillary mobilization on the three-dimensional (3D) nasal morphometry. METHODS Pre- and postsurgery cone beam computed tomography-derived facial image datasets of consecutive patients who underwent two-jaw orthognathic surgery were reviewed. Using preoperative 3D facial models as the positional reference of the skeletal framework, 12-month postoperative 3D facial models were classified into four types of maxillary mobilizations (advancement [n = 83], setback [n = 24], intrusion [n = 55], and extrusion [n = 52]) and four types of final maxillary positions (anterosuperior [n = 44], anteroinferior [n = 39], posterosuperior [n = 11], and posteroinferior [n = 13]). Six 3D soft tissue nasal morphometric parameters were measured, with excellent intra- and interexaminer reliability scores (ICC>0.897) for all the measurements. The 3D nasal change for each nasal parameter was computed as the difference between postoperative and preoperative measurement values. RESULTS The intrusion maxillary mobilization resulted in a significantly (all p<0.05) larger 3D nasal change in terms of alar width, alar base width, and nostril angle parameters, and a smaller change in terms of the nasal tip height parameter than the extrusion maxillary mobilization; however, no significant (all p>0.05) difference was observed between advancement and setback maxillary mobilizations. The anterosuperior and posterosuperior maxillary positions had a significantly (all p<0.05) larger 3D nasal change in terms of the alar base width and nostril angle than the anteroinferior and posteroinferior maxillary positions. CONCLUSION The type of maxillary mobilization affects the 3D nasal morphometry.

Abstract
BACKGROUND There are paucity of studies focused on the long-term assessment of the craniofacial changes after a pi-plasty procedure and self-reported quality of life outcomes. Thus, this study aimed to assess long-term morphologic changes and quality of life of patients with sagittal synostosis who underwent surgery with a modified pi-plasty. METHODS Consecutive patients with sagittal synostosis who underwent surgery and had more than 5 years of follow-up and standard preoperative and 1, 3, and 5 years right profile view photographs were included. Nasofrontal angle and angle of total facial convexity were evaluated using computerized photogrammetric measurements. Additionally, quality of life outcome was evaluated by the Quality of Life Scale Short Form. RESULTS The total facial convexity angle and nasofrontal angle increased significantly (P < 0.05), with a P-value of 0.013 and 0.012, respectively. Patients had quality of life scores >80 in all of the 4 domains, with the highest scores being: physical health domain 80.0 ± 0, psychologic domain 85.0 ± 5, social relationships domain 86.6 ± 0, and environmental domain 98.13 ± 2.42. CONCLUSION Facial angles significantly changed over 5 years of follow-up. Self-reported quality of life instrument showed that patients are satisfied with their own appearance, contributing positively to their quality of life.

Abstract
Skeletally mature patients with cleft lip and palate commonly present with skeletofacial deformities characterized by varying degrees of intrinsic and acquired dentoskeletal and soft tissue abnormalities. These abnormalities are associated with scarring from previous surgeries and the asymmetric midline and facial contour that impose challenges for adequate reconstruction. These patients frequently require 2-jaw orthognathic surgery to improve occlusal function and for correction of facial deformities. In this article, we have detailed a 3-dimensional computer-assisted single-splint 2-jaw orthognathic surgery technique as a surgical approach for cleft skeletofacial reconstruction, allowing for the surgery to be tailored according to the specific needs and requests of the patients. Further, we have addressed the multidimensionality and specificities of cleft treatment, the wide versatility, adaptability, and applicability of this technique, and the patient-centered rationale for the adoption of this method.
