RESUMO
Introduction: Postoperative management following primary cleft lip repair varies across institutions, cleft care teams, and individual surgeons. Postoperative precautions employed after cleft lip repair include dietary restrictions, pacifier limitations, and immobilization, with arm restraints long being used. Yet, restraint distress has led to the exploration of other forms of immobilization. Thus, this study aims to assess cleft lip scar quality and complication rates after postoperative immobilization with arm restraints versus hand mittens. Methods: A retrospective review of patients with unilateral cleft who underwent primary repair with the senior surgeon was done. Data on demographics, surgical characteristics, and immobilization utilized were gathered. A survey with pictures of postoperative scars were sent to laypeople who assessed scar quality with Modified Scar-Rating Scale scores for surface appearance, height, and color of the scar tissue. Statistical analysis was carried out for significance. Results: Twenty-eight patients with a unilateral cleft underwent arm restraints after primary lip repair, and twenty-seven utilized mittens. In total, 42 medical students completed the scar assessment. Photographs were taken an average of 23.9 (±5.8) and 28.2 (±11.9) months postoperatively in the restraint and mitten groups, respectively (p = 0.239). There were no statistically significant differences in scores between scar surface, height, color, or overall scar appearance. Complication rates were also similar between groups. Conclusions: Arm restraints appear to have no additional benefit relative to scar quality, as compared to mittens. Considering the arm restraints' burden of care, mittens should be considered as a measure to protect the lip after primary repair.
RESUMO
The innovative technique of "presurgical lip, alveolus, and nose approximation" (PLANA) offers a new approach within the domain of presurgical infant orthopedics for infants born with cleft lip and palate. Presurgical lip, alveolus, and nose approximation introduces the utilization of the NoseAlign device in conjunction with medical adhesive tapes, designed to approximate and support displaced soft tissue nasolabial structures in patients with cleft, without an intraoral plate. The NoseAlign device, constructed from medical-grade silicone, consists of 2 tubular portions that fit into the nostrils, connected by a columella band. Notably, it also features a wave-shaped and curved horizontal lip band, resting on the upper lip, with elastic clasps for secure attachment to the face with medical adhesive tapes. Presurgical lip, alveolus, and nose approximation therapy employs the NoseAlign device to support the collapsed nasal alar rim and cartilage, the displaced columella, the deviated nasal septum, and the displaced nasal alar base. This innovative approach minimizes the need for frequent office visits, making it particularly suitable for patients residing at a distance from specialized cleft centers. The prefabricated NoseAlign device offers effective support to nasal structures, making it suitable for unilateral and bilateral clefts. Importantly, the absence of an intraoral plate ensures it does not interfere with feeding. Presurgical lip, alveolus, and nose approximation therapy, initiated as early as 1 to 2 weeks, leverages the plasticity of nasal soft tissue and cartilage to achieve the desired nasal form before primary surgery. Although presurgical lip, alveolus, and nose approximation therapy does have some limitations, particularly in cases of medially collapsed alveolar segments, its simplicity, universal applicability, and patient-friendliness make it a promising technique in the presurgical infant orthopedics field.

Nasoalveolar molding (NAM) is an early presurgical intervention to facilitate primary cleft lip repair by reducing cleft severity and improving labial and nasal form. However, it continues to be associated with the burden of care that influences access and completion of therapy. The authors, therefore, aim to determine the burden of care of NAM therapy for families seeking treatment at a high-volume urban cleft center. A retrospective study of all patients undergoing primary cleft repair between 2012 and 2020 was performed. Patients were grouped based on whether or not NAM therapy was offered. Variables including physical, psychosocial, and financial factors were assessed. Two hundred and thirty patients underwent primary cleft repair between 2012 and 2020. Of these, 176 patients were indicated for NAM, with 4% discontinuing, and 54 patients did not undergo NAM. The 169 patients who completed NAM had a mean duration of treatment of 13.6±8.8 wks consisting of 15±6 scheduled NAM adjustment visits and 1±1 unscheduled visit made urgently to assess caregiver concerns. The mean travel distance was 28.6±37.1 miles. Eighty-four percent of caregivers were married, and 16% did not have English as a primary language. Though 57% had private insurance, 43% of patients received charity support for their treatment. NAM is a finite presurgical intervention that requires caregivers to participate in patient care for approximately three months of their early life. The decision to pursue NAM should be considered alongside the burden of care for caregivers to complete treatment.
RESUMO
BACKGROUND: Many cleft centers incorporate NasoAlveolar Molding (NAM) into their presurgical treatment protocols. However, there are limited data on eligible patients who do not receive or complete NAM. This study characterizes the demographics associated with non-utilization or completion of NAM. METHODS: A single-institution retrospective review was performed of all patients with cleft lip and alveolus undergoing primary unilateral and bilateral cleft lip repair from 2012-2020. Patients were grouped based on utilization or non-utilization of NAM. Demographic and treatment data were collected, including documented reasons for not pursuing or completing NAM. RESULTS: Of 230 eligible patients, 61 patients (27%) did not undergo or complete NAM (no-NAM). In this group, 37 (60.7%) received no presurgical intervention, 12 (19.7%) received presurgical nostril retainers, 3 (4.9%) received lip taping, 1 (1.6%) received a combination of taping/nostril retainers, and 8 (13.1%) discontinued NAM. The most common reasons for not receiving NAM were sufficiently aligned cleft alveolus (21.3%), medical complexity (16.4%), late presentation (16.4%), and alveolar notching (18%). Compared to the NAM group, the no-NAM group had significantly lower rates of prenatal cleft diagnosis/consult, and significantly higher proportion of non-married and non-English speaking caregivers. Multivariable analysis controlling for insurance type, primary language, prenatal consult, marital status, and age at first appointment found that age at first appointment is the only statistically significant predictor of NAM utilization (P < .001). CONCLUSIONS: Common reasons for non-utilization of NAM include well-aligned cleft alveolus, medical complexity, and late presentation. Early presentation is an important modifiable factor affecting rates of NAM utilization.

OBJECTIVE: To define "high osteotomy" and determine the feasibility of performing this procedure. DESIGN: Single institution, retrospective review. SETTING: Academic tertiary referral hospital. PATIENTS, PARTICIPANTS: 34 skeletally mature, nonsyndromic patients with unilateral CLP who underwent Le Fort I osteotomy between 2013 and 2020. Patients with cone-beam computed tomography (CBCT) scans completed both pre- (T1) and post-operatively (T2) were included. Patients with bilateral clefts and rhinoplasty prior to post-operative imaging were excluded. INTERVENTIONS: Single jaw one-piece Le Fort I advancement surgery. MAIN OUTCOME MEASURES: Measurements of the superior ala and inferior turbinates were taken from the post-operative CBCT. RESULTS: The sample included 26 males and 8 females, 12 right- and 22 left-sided clefts. The inferior turbinates are above the superior alar crease at a rate of 73.53% and 76.48% on the cleft and non-cleft sides, respectively. One (2.9%) osteotomy cut was above the level of the cleft superior alar crease, and no cuts were above the level of the non-cleft superior ala. On average, the superior ala was 2.63â mm below the inferior turbinates. The average vertical distances from the superior alar crease and the inferior turbinates to the base of the non-cleft side pyriform aperture were 12.17â mm (95% CI 4.00-20.34) and 14.80â mm (95% CI 4.61-24.98), respectively. To complete a "high osteotomy," with 95% confidence, the cut should be 20.36â mm from the base of the pyriform aperture. CONCLUSIONS: A "high" osteotomy is not consistently possible due to the relationship between the superior alar crease and the inferior turbinate.
RESUMO
PURPOSE: Gingivoperiosteoplasty (GPP) can avoid secondary alveolar bone graft in up to 60% of patients. The effects of GPP on maxillary growth are a concern. However, palatoplasty can also negatively impact facial growth. This study quantifies the isolated effects of GPP and cleft palate repair on maxillary growth at the age of mixed dentition. METHODS: A single institution, retrospective study of all patients undergoing primary reconstruction for unilateral cleft lip and alveolus (CLA) or cleft lip and palate (CLP) was performed. Study patients had lateral cephalograms at age of mixed dentition. Patients were stratified into four groups: CLA with GPP (CLA+GPP), CLA without GPP (CLA-GPP), CLP with GPP (CLP+GPP), and CLP without GPP (CLP-GPP). Cephalometric measurements included: sella-nasion-point A (SNA), sella-nasion-point B (SNB), and A point-nasion-B point (ANB). Landmarks were compared between patient groups and to Eurocleft Center D data. RESULTS: 110 patients met inclusion criteria: 7 CLA-GPP, 16 CLA+GPP, 24 CLP-GPP, and 63 CLP+GPP patients. There were no significant differences in SNA, SNB, and ANB between CLA+GPP and CLA-GPP, or between CLP+GPP and CLP-GPP groups. In patients who did not receive GPP, SNA was significantly lower in patients with a cleft palate compared to patients with an intact palate (p < 0.05). There were no significant differences in SNA or SNB of CLP-GPP or CLP+GPP groups when compared to Eurocleft data. CONCLUSION: When controlling for the effects of cleft palate repair, GPP does not appear to negatively affect midface growth at the age of mixed dentition.
RESUMO
BACKGROUND: The long-term effects of nasoalveolar molding (NAM) on patients with bilateral cleft lip and palate (BCLP) are unknown. The authors report clinical outcomes of facially mature patients with complete BCLP who underwent NAM and gingivoperiosteoplasty (GPP). METHODS: A single-institution retrospective study of nonsyndromic patients with complete BCLP who underwent NAM between 1991 and 2000 was performed. All study patients were followed to skeletal maturity, at which time a lateral cephalogram was obtained. The total number of cleft operations and cephalometric measures was compared with a previously published external cohort of patients with complete and incomplete BCLP in which a minority (16.7%) underwent presurgical orthopedics before cleft lip repair without GPP. RESULTS: Twenty-four patients with BCLP comprised the study cohort. All patients underwent GPP, 13 (54.2%) underwent alveolar bone graft, and nine (37.5%) required speech surgery. The median number of operations per patient was five (interquartile range, two), compared with eight (interquartile range, three) in the external cohort ( P < 0.001). Average age at the time of lateral cephalogram was 18.64 years (1.92). There was no significant difference between our cohort and the external cohort with respect to sella-nasion-point A angle (SNA) [73 degrees (6 degrees) versus 75 degrees (11 degrees); P = 0.186] or sella-nasion-point B angle (SNA) [78 degrees (6 degrees) versus 74 degrees (9 degrees); P = 0.574]. Median ANB (SNA - SNB) was -3 degrees (5 degrees) compared with -1 degree (7 degrees; P = 0.024). Twenty patients (83.3%) underwent orthognathic surgery. CONCLUSION: Patients with BCLP who underwent NAM and GPP had significantly fewer total cleft operations and mixed midface growth outcomes at facial maturity compared with patients who did not undergo this treatment protocol. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, III.

This case presents a facially mature patient with Beckwith-Wiedemann Syndrome (BWS) who presented with severe class III malocclusion. Computed tomography imaging revealed an anterior crossbite of 19â mm and a narrow pharyngeal airway at the level of the tongue base precluding mandibular setback surgery. The patient was indicated for a LeFort III combined with a LeFort I advancement, each of 10â mm, for a 20â mm combined advancement. Stable, functional occlusion was achieved without airway compromise. This novel use of the combined LeFort III/I can restore stable class I occlusion in patients with BWS at risk for tongue base airway compromise.

OBJECTIVES: Cleft lip repair has traditionally been performed as an inpatient procedure. There has been an interest toward outpatient cleft lip repair to reduce healthcare costs and avoid unnecessary hospital stay. We report surgical outcomes following implementation of an ambulatory cleft lip repair protocol and hypothesize that an ambulatory repair results in comparable safety outcomes to inpatient repair. DESIGN/SETTING: This is a single-institution, retrospective study. PATIENTS/PARTICIPANTS: Patients undergoing primary unilateral (UCL) and bilateral (BCL) cleft lip repair from 2012 to 2021 with a minimum 30-day follow-up. A total of 226 patients with UCL and 58 patients with BCL were included. INTERVENTION: Ambulatory surgery protocol in 2016. OUTCOME MEASURES: Variables include demographics and surgical data including 30-day readmission, 30-day reoperation, and postoperative complications. RESULTS: There were no differences in rates of 30-day readmission, reoperation, wound complications, or postoperative complications between the pre- and post-protocol groups. Following ambulatory protocol implementation, 80% of the UCL group and 56% of the BCL group received ambulatory surgery. Average length of stay dropped from 24â h pre-protocol to 8â h post-protocol. The 20% of the UCL group and 44% of the BCL group chosen for overnight stay had a significantly higher proportion of congenital abnormalities and higher American Society of Anesthesiology (ASA) class. Reasons for overnight stay included cardiac/airway monitoring, prematurity, and monitoring of comorbidities. There were no differences in surgical outcomes between the ambulatory and overnight stay groups. CONCLUSIONS: An ambulatory cleft lip repair protocol can significantly reduce average length of stay without adversely affecting surgical outcomes.

INTRODUCTION: Simultaneous Le Fort III/I (LF III/I) osteotomies are often performed when a differential advancement of the upper and lower midface is needed. This study aims to evaluate midface position preoperative and 1 week postoperative in patients with severe midface hypoplasia. In addition, this study aims to compare the planned surgical movements to the actual postoperative movements. MATERIALS AND METHODS: A retrospective review was conducted using cephalometry for patients treated with a simultaneous LF III/I osteotomy at a single institution. Osteotomies were performed during 1980-2018 on skeletally mature patients with a craniofacial syndrome, with clinical and radiographic follow-up available. RESULTS: Twelve patients met the inclusion criteria with a mean age of 20.2±6.4 years. Treatment resulted in statistically significant anterior movements related to Orbitale, anterior nasal spine, A Point, and the upper incisor tip, and inferior movements related to anterior nasal spine, A Point, upper and lower incisor tips, B point, and pogonion. Stability after 1 year showed only statistically significant changes at ANB. The predictable error for planned movements versus actual movements was greater in the vertical plane than the horizontal plane. CONCLUSIONS: A simultaneous LF III/I osteotomy significantly improved the midface position and occlusal relationship in syndromic patients with midface hypoplasia in a predictable manner. Further multicenter studies with larger sample sizes are needed to validate the conclusions.

The current standard of care for an alveolar cleft defect is an autogenous bone graft, typically from the iliac crest. Given the limitations of alveolar bone graft surgery, such as limited supply, donor site morbidity, graft failure, and need for secondary surgery, there has been growing interest in regenerative medicine strategies to supplement and replace traditional alveolar bone grafts. Though there have been preliminary clinical studies investigating bone tissue engineering methods in human subjects, lack of consistent results as well as limitations in study design make it difficult to determine the efficacy of these interventions. As the field of bone tissue engineering is rapidly advancing, reconstructive surgeons should be aware of the preclinical studies informing these regenerative strategies. We review preclinical studies investigating bone tissue engineering strategies in large animal maxillary or mandibular defects and provide an overview of scaffolds, stem cells, and osteogenic agents applicable to tissue engineering of the alveolar cleft. An electronic search conducted in the PubMed database up to December 2021 resulted in 35 studies for inclusion in our review. Most studies showed increased bone growth with a tissue engineering construct compared to negative control. However, heterogeneity in the length of follow up, method of bone growth analysis, and inconsistent use of positive control groups make comparisons across studies difficult. Future studies should incorporate a pediatric study model specific to alveolar cleft with long-term follow up to fully characterize volumetric defect filling, cellular ingrowth, bone strength, tooth movement, and implant support.

BACKGROUND/PURPOSE: This paper describes the changes in maxillary arch morphology in infants with bilateral cleft lip and palate (BCLP) following nasoalveolar molding (NAM) and with follow up to assess the need for secondary alveolar bone grafting (ABG) and premaxillary repositioning surgery at preadolescence. METHODS/DESCRIPTION: Treatment records of infants with BCLP treated with NAM between 2003 and 2013 were reviewed. Patients with complete BCLP who underwent NAM and had complete sets of maxillary casts at T 0 pre-NAM (mean = 27 days), T 1 post-NAM (mean = 6 months and 5 days), and T 2 before palate surgery (mean = 11 months and 15 days) were included. The sample comprised 23 infants (18 male, 5 female). Casts were digitized and analyzed using three dimensional software. The need for secondary ABG and premaxillary repositioning surgery was assessed at preadolescent follow-up (mean = 8.3 years). RESULTS: Cleft width was reduced on average by 4.73 mm (SD±3.15 mm) and 6.56 mm (SD±4.65) on the right and left sides, respectively. At T 1, 13 (56.52%) patients underwent bilateral gingivoperiosteoplasty (GPP), 8 (34.78%) patients unilateral GPP, and 2 patients (8.7%) did not undergo GPP. 34/46 clefts sites (73.91%) underwent GPP while 12 (26.08%) did not. At preadolescent follow-up of 19 patients, 7 patients (36.84%) did not need ABG on either side, 8 (42.10%) needed ABG on 1 side, and 4 (21.05%) needed ABG on both sides. None of the patients needed premaxillary repositioning surgery. CONCLUSIONS: Nasoalveolar molding treatment significantly improves the position of the premaxilla before primary repair, and there is a significant reduction in the need for secondary ABG and premaxillary repositioning surgery at preadolescence.

PURPOSE: To examine the growth rate discrepancy of the affected and unaffected ramus heights in Pruzansky Type I and Type II mandibles. METHODS: This is a serial retrospective longitudinal growth study of 30 untreated patients (21 males and 9 females) with UCMF (age range from 5 years to 14 years). The mean age of patients was 8.5 years, and the mean follow-up records were 3.7 years. There were 13 patients in group I with a Pruzansky Type I mandible and 17 patients in group II with a Pruzansky Type II. The unaffected side of the mandible served as a control. Eighteen cephalometric parameters were examined at each of the two-time intervals. RESULTS: In patients with Pruzansky Type I mandible, the affected ramus grew on average 1.41â mm per year; the unaffected ramus grew 1.66â mm per year during the same period. In patients with Pruzansky Type II mandible, the affected ramus grew on average 0.84â mm per year; during the same period, unaffected ramus grew 1.79 per year. When the growth rate of the ramus height on the affected side was compared to the unaffected side, there was no statistically significant difference in Pruzansky Type I mandibles (p > .05); however, there was a statistically significant difference in the Pruzansky Type II mandibles (p < .05). CONCLUSION: The growth rate discrepancy of the affected and unaffected ramus heights was more severe in Pruzansky Type II mandibles than Pruzansky Type I mandibles explaining the progressive nature of facial asymmetry in Pruzansky II mandibles.

To compare lower lip changes after Le Fort I advancement surgery in patients with a cleft.Single institution, retrospective review.Academic tertiary referral hospital.Skeletally mature patients with a cleft who underwent one-piece Le Fort I advancement surgery who had a lateral cephalogram or cone-beam computed tomography (CBCT) scan preoperatively and at least 6 months postoperatively. Patients who underwent concomitant mandibular surgery or genioplasty were excluded. 64 patients were included: 45 male and 19 female, 25 with BCLP and 39 with UCLP. The mean age at surgery was 18.4 years.Single jaw one-piece Le Fort I advancement surgery.Standard lateral cephalometric landmarks of the bony skeleton and soft tissue were compared before and after Le Fort I advancement. Pearson correlation coefficients (r) were calculated to measure the correlation between lower lip position and other soft and hard tissue changes.After comparable maxillary advancements [BCLP: 7.2â mm (95% CI: 6.2-8.3â mm), UCLP: 6.4â mm (95% CI: 5.7-7.0â mm)] the horizontal upper-to-lower lip discrepancy significantly improved in both groups. The lower lip became thinner and more posteriorly positioned. Changes in lower lip position correlated strongly with mandibular bony landmarks and moderately with upper lip position, but poorly with maxillary landmarks.Le Fort I advancement results in posterior displacement of the lower lip and better lip competence, thereby improving facial harmony. This lower lip change is not predictable by degree of maxillary advancement, and does not differ in patients with BCLP vs. UCLP.
RESUMO
Presurgical infant orthopedic (PSIO) therapy has evolved in both its popularity and focus of treatment since its advent. Nasoalveolar molding, nasal elevators, the Latham appliance, lip taping, and passive plates are the modern treatment options offered by cleft teams. Many cleft surgeons also employ postsurgical nasal stenting (PSNS) after the primary lip repair procedure. The purpose of this study is to examine trends in current PSIO care as well as PSNS for the management of patients with cleft lip and palate. An electronic survey was distributed to cleft team coordinators listed by the American Cleft Palate Association. The survey reported on team setting, provider availability, PSIO offerings, contraindications, and use of PSNS. Descriptive statistics and analyses were performed using MS Excel and SPSS. A total of 102 survey responses were received. The majority of settings were children's specialty hospitals (66%) or university hospitals (27%). Presurgical infant orthopedics was offered by 86% of cleft teams, and the majority of those (68%) provided nasoalveolar molding. Nasal elevators and lip taping are offered at 44% and 53% of centers, respectively. Latham and passive plates are both offered at 5.5% of centers. Most centers had an orthodontist providing treatment. The majority of centers use PSNS (86%). Nasoalveolar molding is the most popular PSIO technique in North American cleft centers followed by the nasal elevator, suggesting that the nasal molding component of PSIO is of critical influence on current treatment practices.

OBJECTIVE: The aim of this study was to evaluate the outcomes of orthognathic surgery (OGS) in patients with craniofacial microsomia (CFM) who had previously undergone mandibular distraction osteogenesis (MDO). DESIGN: A retrospective cohort study was performed including all patients with CFM who were treated with OGS at a single institution between 1996 and 2019. The clinical records, operative reports, and cone beam computed tomography (CBCT) scans were reviewed. CBCT data before OGS (T1), immediately after OGS (T2), and at long-term follow-up (T3) were analyzed using Dolphin three-dimensional software to measure the occlusal cant and chin point deviation. RESULTS: The study included 12 patients with CFM who underwent OGS (6 underwent OGS without MDO and 6 underwent OGS after MDO). There was a statistically significant improvement in occlusal cant and chin point deviation in both groups postoperatively. Occlusal cant relapsed by a mean of 0.6° (standard deviation [SD] 1.1°) in the patients who had OGS alone compared with 0.7° (SD 1.2°) in the patients who had OGS after MDO (P = .745) between T2 and T3. There was no statistically significant difference in chin point relapse between patients who had OGS alone compared with those who had OGS after MDO (0.1 mm [SD 2.5mm] vs 0.7mm [SD 2.2mm]; P = .808). CONCLUSIONS: Within the limitations of this study, these findings suggest that OGS after MDO in patients with CFM can produce stable results.
RESUMO
BACKGROUND: The aim of this investigation was to determine whether the nasal form of patients with unilateral cleft lip and palate treated with presurgical nasoalveolar molding therapy, primary lip-nose surgery, and postsurgical nostril retainer was different from that of patients treated with presurgical nasoalveolar molding and primary lip and nose surgery alone. METHODS: This cross-sectional, retrospective review focused on 50 consecutive patients with nonsyndromic unilateral cleft lip and palate: 24 treated with nasoalveolar molding and primary lip and nose surgery followed by postsurgical nostril retainer (group 1) compared with 26 patients treated with nasoalveolar molding and primary lip and nose surgery without postsurgical nostril retainer (group 2). Polyvinyl siloxane nasal impressions were performed at an average age of 12 months and 6 days. Bilateral measurements of alar width at maximum convexity, total alar base width, nasal tip projection, columella length, and nostril aperture width and height were recorded. Statistical comparisons of cleft-side versus noncleft side nasal measurements were performed within group 1 and group 2, as well as comparisons of differences between the two groups. RESULTS: Cleft-side nasal dimension was statistically significantly better in group 1 than in group 2 across all measures except nasal projection ( p < 0.05). Group 1 showed less difference between the cleft side and noncleft side in all six measurements than did group 2 ( p < 0.05). CONCLUSIONS: There was a significant difference in the nasal shape of patients who used a postsurgical nostril retainer compared with those who did not. Patients who used a postsurgical nostril retainer showed better nasal shape at an average age of 12 months compared with the control group. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, III.

OBJECTIVE: This study evaluates skeletal and dental outcomes of LeFort I advancement surgery in patients with cleft lip and palate (CLP) with varying degrees of maxillary skeletal hypoplasia. DESIGN: Retrospective study. METHOD: Lateral cephalograms were digitized at preoperative (T1), immediately postoperative (T2), and 1-year follow-up (T3) and compared to untreated unaffected controls. Based on the severity of cleft maxillary hypoplasia, the sample was divided into 3 groups using Wits analysis: mild: ≤0 to ≥-5 mm; moderate: <-5 to >-10 mm; and severe: ≤-10 mm. PARTICIPANTS: Fifty-one patients with nonsyndromic CLP with hypoplastic maxilla who met inclusion criteria. INTERVENTION: LeFort I advancement. MAIN OUTCOME MEASURE: Skeletal and dental stability post-LeFort I surgery at a 1-year follow-up. RESULTS: At T2, LeFort I surgery produced an average correction of maxillary hypoplasia by 6.4 ± 0.6, 8.1 ± 0.4, and 10.7 ± 0.8 mm in the mild, moderate, and severe groups, respectively. There was a mean relapse of 1 to 1.5 mm observed in all groups. At T3, no statistically significant differences were observed between the surgical groups and controls at angle Sella, Nasion, A point (SNA), A point, Nasion, B point (ANB), and overjet outcome measures. CONCLUSIONS: LeFort I advancement produces a stable correction in mild, moderate, and severe skeletal maxillary hypoplasia. Overcorrection is recommended in all patients with CLP to compensate for the expected postsurgical skeletal relapse.

OBJECTIVE: Utilize 3-dimensional (3D) photography to evaluate the nasolabial changes in infants with bilateral cleft lip and palate (BCLP) who underwent nasoalveolar molding (NAM) and primary reconstructive surgery. DESIGN: This is a retrospective serial longitudinal study of consecutively enrolled infants from September 2012 to July 2016 with BCLP who underwent NAM before primary lip and nose reconstructive surgery. It included infants who had digital 3dMD stereophotogrammetry records at initial presentation (T1), completion of NAM (T2), and 3 weeks following primary repair (T3). Twelve infants fulfilled the inclusion criteria. 3dMD Vultus software was used to orient images and plot 16 nasolabial points with x, y, z coordinates to obtain the linear and angular measurements. Nasal form changes were measured and analyzed between T1 (0.5 months old), T2 (5 months old), and T3 (6 months old). Intraclass correlation coefficient was performed for intrarater reliability. Averaged data from the 3D images was statistically analyzed from T1 to T2 and T2 to T3 with Wilcoxon tests. Unaffected infant norms from the Farkas publication were used as a control sample. RESULTS: After NAM therapy, statistically significant changes in the position of subnasale and labius superius improved nasolabial symmetry. Both retruded after NAM were displaced downward after NAM and surgical correction with respect to soft tissue nasion. The nasal tip's projection was maintained with NAM and surgical correction. The columella lengthened from 1.4 to 4.71 mm following NAM. CONCLUSIONS: There was a significant improvement in the nasolabial anatomy after NAM, and this was further enhanced after primary reconstructive surgery.

OBJECTIVE: To compare the prevalence of dental malformations and agenesis in patients who received or did not receive gingivoperiosteoplasty (GPP). DESIGN: Retrospective cohort study. PATIENTS: Review of patients born January 1, 2000, to December 31, 2007, with unilateral cleft lip and alveolus, with or without clefting of the secondary palate, who received GPP and/or secondary alveolar bone grafting (ABG). Patients were included if they had clinical images and dental radiographs available at ages 5 to 9 and 10 to 12 years. Ninety-four patients met the inclusion criteria; 46 treated with GPP, and 48 who did not receive GPP. OUTCOME MEASURES: Records were assessed for supernumerary, missing, and malformed teeth by a blinded examiner, and prevalence compared between groups using χ2 tests. RESULTS: Cleft side lateral incisors were absent in 54% of GPP patients, compared to 50% in the no-GPP group. Two patients in the GPP group and 1 in the no-GPP group had supernumerary lateral incisors. Most lateral incisors were undersized or peg shaped in both the no-GPP (83.3%) and GPP (71.4%) groups. In the GPP group, 5 (10.9%) patients exhibited central incisor agenesis, and 3 had significant hypoplasia. In the no-GPP group, 4 (8.3%) patients exhibited central incisor agenesis, and 5 (10.5%) significant hypoplasia. These differences were not statistically significant. CONCLUSIONS: Gingivoperiosteoplasty was not associated with increased prevalence of dental malformation or agenesis. When performed appropriately, GPP is a safe treatment technique that does not increase the risk of dental anomalies.
