Effect of One-Stage Bilateral Cleft Lip, Nose, and Alveolus Repair Following Nasoalveolar Molding on the Premaxilla Position at Preadolescence: An 8-Year Retrospective Study.

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.

Simultaneous Le Fort III and Le Fort I Osteotomy: Surgical Outcomes and Clinical Parameters.

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.

Longitudinal Skeletal Growth Analysis of Mandibular Asymmetry in Unoperated Patients With Unilateral Craniofacial Microsomia (UCFM).

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 1.41 mm per year; the unaffected ramus grew 1.66 mm per year during the same period. In patients with Pruzansky Type II mandible, the affected ramus grew on average 0.84 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.

The First Hybrid International Educational Comprehensive Cleft Care Workshop.

OBJECTIVE: Describe the first hybrid global simulation-based comprehensive cleft care workshop, evaluate impact on participants, and compare experiences based on in-person versus virtual attendance. DESIGN: Cross-sectional survey-based evaluation. SETTING: International comprehensive cleft care workshop. PARTICIPANTS: Total of 489 participants. INTERVENTIONS: Three-day simulation-based hybrid comprehensive cleft care workshop. MAIN OUTCOME MEASURES: Participant demographic data, perceived barriers and interventions needed for global comprehensive cleft care delivery, participant workshop satisfaction, and perceived short-term impact on practice stratified by in-person versus virtual attendance. RESULTS: The workshop included 489 participants from 5 continents. The response rate was 39.9%. Participants perceived financial factors (30.3%) the most significant barrier and improvement in training (39.8%) as the most important intervention to overcome barriers facing cleft care delivery in low to middle-income countries. All participants reported a high level of satisfaction with the workshop and a strong positive perceived short-term impact on their practice. Importantly, while this was true for both in-person and virtual attendees, in-person attendees reported a significantly higher satisfaction with the workshop (28.63 ± 3.08 vs 27.63 ± 3.93; P = .04) and perceived impact on their clinical practice (22.37 ± 3.42 vs 21.02 ± 3.45 P = .01). CONCLUSION: Hybrid simulation-based educational comprehensive cleft care workshops are overall well received by participants and have a positive perceived impact on their clinical practices. In-person attendance is associated with significantly higher satisfaction and perceived impact on practice. Considering that financial and health constraints may limit live meeting attendance, future efforts will focus on making in-person and virtual attendance more comparable.

Prevalence of Dental Anomalies in Patients With Unilateral Cleft Lip and Alveolus Treated With Gingivoperiosteoplasty.

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.

Three-Dimensional Nasolabial Changes After Nasoalveolar Molding and Primary Lip/Nose Surgery in Infants With Bilateral Cleft Lip and Palate.

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.

Correction of Severe Facial Asymmetry in Patients With Unilateral Craniofacial Microsomia Using Computer-Aided Design/Computer-Aided Manufacturing Technology: An Evaluation of Postsurgical Results.

ABSTRACT: This is a retrospective study to evaluate the postsurgical position of the maxilla and mandible in 5 matured craniofacial patients with unilateral craniofacial microsomia who underwent 2 jaw surgical procedures using computerized surgical planning. The craniofacial surgeon and orthodontist completed the virtual surgical treatment plan with a biomedical engineer's assistance via a web meeting. The treatment plan of each patient included 2 jaw surgery with genioplasty. At the maxillary dental midline, the planned mean advancement was 4 mm; yaw, a rotational correction towards the unaffected side was 4.96 mm; and impaction was 2.74 mm. The mean advancement measured at point B was 10.5 mm, and the rotational correction towards the unaffected side was 6.58 mm. The mean advancement following genioplasty was 8.43 mm, and the mean transverse correction was 6.33 mm towards the midsagittal plane. The intermediate surgical splint, final surgical splint, bone graft templates, and cutting guides were constructed utilizing computer-aided design/computer-aided manufacturing technology. The surgeon executed the treatment plan in the operating room using appropriate computer-generated guides and splints. A postsurgical cone-beam computed tomography scan was obtained and superimposed on the surgical treatment plan using Simplant OMS 10.1 software. The cranial base was used as a reference for superimposition. Three-dimensional color-coded displacement maps were generated to visually and quantitatively assess the surgical outcome. There was a mean error of 0.88 mm (+0.30) for the position of the maxillary anatomical structures from the planned position, and the anterior mandibular anatomical structures were on average 0.96 mm (+0.26) from the planned position.

One-Year Stability of LeFort I Advancement in Patients With Complete Cleft Lip and Palate Using a Standardized Clinical and Surgical Protocol.

AIM: To assess treatment outcome and 1-year stability of LeFort I advancement in patients with complete cleft lip and palate. METHODS: Thirty-five patients (age 20.65 ±â€Š2.20 years) with unilateral (n = 25) or bilateral (n = 10) complete cleft lip and palate who underwent LeFort I advancement were included.Lateral cephalograms before surgery (T1), immediately postsurgery (T2), and at 1-year follow-up (T3) were superimposed, and the position of anterior nasal spine (ANS), A-point, and U1 Tip assessed using an x, y coordinate system. Differences between landmark positions at the 3-time points were analyzed using paired sample t-tests, with a significance defined as α ≤ 0.05. RESULTS: The mean surgical advancement in the horizontal direction (T2-T1) was 6.50 ±â€Š2.62 mm at ANS (P < 0.001) and 7.05 ±â€Š2.51 mm at A-point (P < 0.001). At a 1-year follow-up (T3-T2), the mean horizontal relapse at ANS was -1.41 ±â€Š1.89 mm (P < 0.001) and -0.79 ±â€Š1.48 mm at A-point (P 0.003). Mean horizontal relapse was 21.7% and 11% of surgical advancement when assessed at ANS and A-point, respectively. The central incisor tip position remained stable during the postsurgical period (0.12 ±â€Š2.11 mm, P 0.732). At A-point, the mean vertical surgical change (T2-T1) was -0.96 ±â€Š2.57 mm (P < 0.001). No significant post-treatment (T3-T2) vertical changes were detected at ANS or A-point. Phenotypic stability was excellent, with all patients maintaining positive overjet at 1-year follow-up. CONCLUSIONS: LeFort I advancement in complete cleft lip and palate is stable, with less than a 2 mm relapse after 1-year. Surgical overcorrection by 10% to 20% is recommended to compensate for the expected skeletal relapse.

Sociodemographic Predictors of Treatment Success and Difficulty in Nasoalveolar Molding.

OBJECTIVE: To assess social and demographic influences on caregiver success and difficulty with nasoalveolar molding (NAM). DESIGN: Retrospective review identified patients who began NAM between April 22, 2013, and April 18, 2017, at the New York University Langone Medical Center. Records were reviewed, and the following sociodemographic data retrieved: parental marital status, parental ages, number of siblings, distance traveled to clinic, insurance coverage, concurrent medical conditions, and need for an interpreter. PATIENTS: Patients were included if complete charting was available; 106 patients met the inclusion criteria; 79 patients with unilateral and 27 with bilateral clefts. OUTCOME MEASURES: Chart entries indicating incorrect appliance usage, emergency visits, phone calls, and noncompliance were recorded. Alveolar cleft gap closure was measured on pre- and posttreatment models in unilateral cases. Multiple regression analyses were performed to assess the influence of social variables on these outcomes. RESULTS: Alveolar cleft gap closure was 7.2 ± 3.0 mm, or 78.5% ± 19.1%. Cleft closure increased with paternal age by 0.33 mm (P = .007) or 2.0% (P = .017) per year, decreased with maternal age by 0.29 mm (P = .041) per year, and increased in married and partnered parents by 39% (P = .018). Incorrect appliance usage averaged 0.62 fewer instances for married and partnered parents (P = .018) and 0.43 fewer for those with private insurance (P = .019). CONCLUSIONS: Alveolar cleft gap closure was more successful for older fathers, younger mothers, and married couples. Married couples were also less likely to experience treatment difficulties such as incorrect appliance usage or inadequate duration of wear, as were those with private insurance coverage.

The Effects of Nasoalveolar Molding on Nasal Proportions at the Time of Nasal Maturity.

BACKGROUND: The aim of this study is to assess the effect of nasoalveolar molding (NAM) versus no-NAM on nasal morphology in patients with unilateral cleft lip and palate (UCLP) at the time of nasal maturity. METHODS: A retrospective, single-institution review was conducted on all non-syndromic patients with UCLP. Inclusion criteria included age 14 years or above, unilateral cleft repair at the time of infancy, and adequate photography taken at nasal maturity and prior to rhinoplasty. Exclusion criteria included age less than 14 years, syndromic diagnosis, and rhinoplasty prior to nasal maturity. Ten parameters were measured twice from standardized clinical photographs using the Dolphin Imaging Software for establishment of intrarater reliability. Subjective analysis was achieved through completion of the Asher McDade grading scale by 3 expert cleft practitioners. RESULTS: Nostril height, columellar angle, alar cant, vertical alar height, alar height angle, nasofacial angle, and nasolabial angle were found to be significantly less severe in patients who had undergone NAM in conjunction with surgical repair when compared with those who had undergone surgical repair alone. Asher McDade grading revealed significant improvement in nasal form, nasal symmetry/deviation, nasal profile, vermillion border, and overall score in patients who underwent NAM compared to no-NAM. CONCLUSION: The use of presurgical NAM during infancy can improve nasal symmetry and nasal proportions at the time of nasal maturity.

Midface Growth in Patients With Unilateral Cleft Lip and Palate Treated With a Nasoalveolar Molding Protocol.

This retrospective cohort study aimed to determine the impact of a nasoalveolar molding (NAM) protocol on midface growth in school-aged children with non-syndromic unilateral cleft lip and palate (UCLP). Data from 56 consecutively treated, NAM-prepared, Caucasian patients with non-syndromic UCLP from a single US cleft palate center were compared to pooled center data based on 56 patients with non-syndromic UCLP treated at 2 Eurocleft centers that did not use presurgical infant orthopedics (non-PSIO). Lateral cephalograms were obtained and 28 landmarks were identified. Published cephalometric measurements from Eurocleft centers were used for comparison. Seven cephalometric measurements (SNA, SNB, ANB, A'N'B', G'-Sn'-Pg', Sn-CT-LS, ANS-Me/N-Me%), available or derivable for both centers, were analyzed. Means and standard deviations for the 7 measurements were calculated for the NAM center. Student's t-tests were used to compare group means for 6 of the measures and a test of proportion was used for ANS-Me/N-Me%. No significant differences were found between the NAM protocol-prepared group and the Eurocleft non-PSIO centers on any of the 7 analyzed cephalometric relationships after accounting for false discovery rate. The NAM treatment protocol does not appear to impact skeletal or soft tissue facial growth in school-aged children with non-syndromic UCLP.

Three-Dimensional Soft Tissue Nasal Changes After Nasoalveolar Molding and Primary Cheilorhinoplasty in Infants With Unilateral Cleft Lip and Palate.

OBJECTIVE: To quantify 3-dimensional (3D) nasal changes in infants with unilateral cleft lip with or without cleft palate (UCL±P) treated by nasoalveolar molding (NAM) and cheilorhinoplasty and compare to noncleft controls. DESIGN: Retrospective case series of infants treated with NAM and primary cheilorhinoplasty between September, 2012 and July, 2016. Infants were included if they had digital stereophotogrammetric records at initial presentation (T1), completion of NAM (T2), and following primary cheilorhinoplasty (T3). Images were oriented in 3dMD Vultus software, and 16 nasolabial points identified. PATIENTS: Twenty consecutively treated infants with UCL±P. INTERVENTIONS: Nasoalveolar molding and primary cheilorhinoplasty. MAIN OUTCOME MEASURES: Anthropometric measures of nasal symmetry and morphology were compared in the treatment group between time points using paired Student t tests. Postsurgical nasal morphology was compared to noncleft controls. RESULTS: Nasal tip protrusion increased, and at T3 was 2.64 mm greater than noncleft controls. Nasal base width decreased on the cleft side by 4.01 mm after NAM and by 6.73 mm after cheilorhinoplasty. Columellar length of the noncleft to cleft side decreased from 2:1 to 1:1 following NAM. Significant improvements in subnasale, columella, and nasal tip deviations from midsagittal plane were observed. Treatment improved symmetry of the alar morphology angle and the nasal base-columella angle between cleft and noncleft sides. CONCLUSIONS: Three-dimensional analysis of UCL±P patients demonstrated significant improvements in nasal projection, columella length, nasal symmetry, and nasal width. Compared to noncleft controls, nasal form was generally corrected, with overcorrection of nasal tip projection, columella angle, and outer nasal widths.

Nasolabial Aesthetics Following Cleft Repair: An Objective Evaluation of Subjective Assessment.

OBJECTIVE: Assess the weight and contribution of each of the parameters of the Asher-McDade Scale to overall subjective assessment of nasolabial aesthetics following cleft lip repair. DESIGN: Retrospective cohort evaluation. SETTING: Cleft and craniofacial center. PARTICIPANTS: Forty-one patients who underwent unilateral cleft lip repair. INTERVENTIONS: Unilateral cleft lip repair. MAIN OUTCOME MEASURES: Nasolabial rating using the Asher-McDade scale and overall subjective assessment of nasolabial aesthetics using a rank score following unilateral cleft lip repair. RESULTS: Strong interrater reliability was observed between the 3 raters. Significant association was determined on bivariate analysis between nasal form score (ß = 27.06; P < .001), nasal symmetry score (ß = 26.41; P < .001), nasal profile score (ß = 28.75; P < .001), vermilion border score (ß = 13.40; P = .012), and the ranking score. Adjusted ß coefficients obtained from multivariate regression analysis were used to develop a modified nasolabial appearance score (over 5), that is, weighted for each of the 4 parameters: nasal form (over 8, adjusted ß = 14.33), nasal symmetry (over 5, adjusted ß = 7.96), nasal profile (over 5, adjusted ß = 9.44), and vermilion (over 2, adjusted ß = 3.31). Regression analysis between our modified nasolabial appearance score and patient ranking score demonstrated superior goodness of fit when compared to the Asher-McDade overall nasolabial appearance score (R2 = .80; P < .001 vs R2 = .69; P < .001). CONCLUSION: The parameters evaluated in the Asher-McDade scale have different weights and contribute differently to overall subjective assessment of nasolabial aesthetic outcomes following cleft lip repair. Adjusting for their weights results in a modified score that demonstrates superior correlation with overall subjective assessment of nasolabial aesthetic outcomes.

Maxillomandibular and occlusal relationships in preadolescent patients with syndromic craniosynostosis treated by LeFort III distraction osteogenesis: 10-year surgical and phenotypic stability.

INTRODUCTION: LeFort III distraction osteogenesis may be indicated in the treatment of syndromic craniosynostosis with severe midface retrusion. This study investigates long-term changes in patients undergoing distraction as children, and compares outcomes to an unaffected, untreated control. METHODS: Fifteen patients (9 males, 6 females) with syndromic craniosynostosis treated by LeFort III distraction at an average age of 4.9 ± 1.5 years were identified. Lateral cephalograms at predistraction, immediate, 1-, 5-, and 10-year postdistraction were superimposed using the best-fit of cranial base details. An untreated, unaffected matched control was obtained from the American Association of Orthodontists Foundation Legacy Collection. Differences in landmark location and cephalometric relationships were assessed between time points and between treatment and control groups. RESULTS: LeFort III distraction produced an average advancement of 14.86 ± 5.14 mm at A-point and 10.54 ± 3.78 mm at orbitale. This advancement produced overcorrection of anteroposterior occlusal relationships and phenotypic correction of midface position. Surgical stability over a 10-year follow-up was excellent. Posttreatment growth was characterized by absent anteroposterior maxillary growth, preservation of dentoalveolar development and maxillary remodeling, and delayed mandibular growth. Subsequent growth resulted in a long-term phenotypic relapse of pretreatment Class III maxillomandibular relationship and negative overjet. CONCLUSIONS: LeFort III distraction osteogenesis produces stable advancement of the midface. Overcorrection is required for long-term phenotypic stability because of deficient postdistraction sagittal midface growth. Late mandibular growth contributes to underestimation of the amount of distraction required to produce long-term phenotypic correction.

Proptosis Correction in Pre-Adolescent Patients With Syndromic Craniosynostosis by Le Fort III Distraction Osteogenesis.

Le Fort III distraction osteogenesis may be indicated in the treatment of syndromic craniosynostosis with severe midface retrusion and proptosis. This study assesses the stability of proptosis correction over 10-years.A retrospective review identified 15 patients with syndromic craniosynostosis treated by Le Fort III distraction prior to age 10 (9 males, 6 females; age 4.9 ±â€Š1.5 years). Untreated, non-craniosynostotic age- and gender-matched controls were obtained from historical growth records. Lateral cephalometric tracings at pre-surgery (T1), immediate (T2), 1 year (T3), 5 years (T4), and 10 years (T5) (n = 11) post-distraction were superimposed using the best-fit of cranial base. Proptosis severity was defined as the horizontal distance between the Ant. Globe cephalometric point and orbital rim landmarks Orbitale and Lat. Orbit.The orbital rim advanced 10.54 ±â€Š3.78 mm (P < 0.001) at Orbitale and 9.73 ±â€Š4.54 mm (P > 0.001) at Lat. Orbit from T1 to T2; Ant. Globe advanced 3.13 ±â€Š3.02 mm (p 0.001). Proptosis decreased 7.41 ±â€Š5.29 mm (P < .001) from Orbitale and 6.60 ±â€Š6.50 mm (p 0.002) from Lat. Orbit. Comparison to controls demonstrated phenotypic correction. In craniosynostotic patients from T2 to T5, the bony orbital rim demonstrated non-significant remodeling posteriorly and inferiorly. Anterior Globe moved 3.79 ±â€Š1.47 mm anteriorly (P < .001), which did not differ significantly from controls. Proptosis increased by 4.18 ±â€Š2.94 mm in craniosynostotic patients from T2 to T5.Le Fort III distraction was stable, with no significant anteroposterior relapse of the maxilla or bony orbit. Phenotypic relapse of proptosis to pre-treatment levels occurred through deficient growth of the midface, surface resorption at the orbital rim, and preservation of normal forward movement of Ant. Globe.

Palatal and Alveolar Tissue Deficiency in Infants With Complete Unilateral Cleft Lip and Palate.

OBJECTIVE: To investigate intrinsic palatal and alveolar tissue deficiency in patients with unilateral cleft lip and palate (UCLP) as compared to age-matched individuals without UCLP using surface area measurements on 3D scans of plaster casts. METHODS: 22 maxillary casts of infants with UCLP from the Wyss Department of Plastic Surgery of NYU Langone Medical Center and 37 maxillary casts from infants without clefts from Sillman's longitudinal study were scanned by Ortho Insight 3D by Motion View Software, LLC (Chattanooga, TN) and measured using Checkpoint software (Stratovan, Davis, CA). The palatal and alveolar surface areas of each cast were measured. The most superior point of the alveolar ridge in front of the incisive papilla and the most superior point of each maxillary tuberosity were connected by a line that ran along the highest part of the alveolar ridge. This line was used to set boundaries for the palatal surface area measurements. The surface areas of greater and lesser segments were measured independently on UCLP casts. A total palatal surface area for the UCLP sample including width of the cleft gap was also measured. RESULTS: There was a statistically significant difference in surface area (P > .001) when we compared the UCLP area of the cleft segments alone with the non-cleft sample. There was a positive correlation (determine the statistical significance) between the surface area of the cleft segments and cleft gap. In addition, there was a statistically significant difference between UCLP plus cleft area and the non-cleft samples in surface area (P < .0001). CONCLUSION: An intrinsic palatal and alveolar tissue deficiency exists in patients born with UCLP. The amount of tissue deficiency for a patient with UCLP should be considered when developing and executing a patient-specific treatment plan.

Comparative Analysis of Three-Dimensional Nasal Shape of Casts from Patients With Unilateral Cleft Lip and Palate Treated at Two Institutions Following Rotation Advancement Only (Iowa) or Nasoalveolar Molding and Rotation Advancement in Conjunction With Primary Rhinoplasty (New York).

OBJECTIVES: To compare 3-dimensional nasal symmetry in patients with UCLP who had either rotation advancement alone or nasoalveolar molding (NAM) followed by rotation advancement in conjunction with primary nasal repair. DESIGN: Pilot retrospective cohort study. MATERIALS AND METHODS: Nasal casts of 23 patients with UCLP from 2 institutions were analyzed; 12 in the rotation advancement only group (Iowa) and 11 in the NAM, rotation advancement with primary nasal repair group (New York). Casts from patients aged 6 to 18 years were scanned using the 3Shape scanner and 3-dimensional analysis of nasal symmetry performed using 3dMD Vultus software, Version 2507, 3dMD, Atlanta, GA. Cleft and noncleft side columellar height, nasal dome height, alar base width, and nasal projection were linearly measured. Inter- and intragroup analyses were performed using t tests and paired t tests as appropriate. RESULTS: A statistically significant difference in mean-scaled 3-dimensional asymmetry index was found between groups with group 1 having a larger measure of asymmetry (4.69 cm3) than group 2 (2.56 cm3; P = .02). Intergroup analysis performed on the most sensitive linear measure, alar base width, revealed significantly less asymmetry on average in group 2 than in group 1 ( P = .013). CONCLUSION: This study suggests the NAM followed by rotation advancement in conjunction with primary nasal repair approach may result in less nasal asymmetry compared to rotation advancement alone.

Breast Milk Feeding Rates in Patients With Cleft Lip and Palate at a North American Craniofacial Center.

OBJECTIVE: Our study goal was to evaluate the rates of breast milk feeding among patients with oral clefts at a large North American Craniofacial Center. METHODS: Parents of patients with oral clefts born from 2000 to 2012 and treated at our center were interviewed regarding cleft diagnosis, counseling received for feeding, and feeding habits. RESULTS: Data were obtained from parents of 110 patients with oral clefts. Eighty-four percent of parents received counseling for feeding a child with a cleft. Sixty-seven percent of patients received breast milk for some period of time with a mean duration of 5.3 months (range 0.25 to 18 months). When used, breast milk constituted the majority of the diet with a mean percentage of 75%. Breast milk feeding rates increased successively over the 13-year study period. The most common method of providing breast milk was the Haberman feeder at 75% with other specialty cleft bottles composing an additional 11%. Parents who received counseling were more likely to give breast milk to their infant (P = .02). Duration of NasoAlveolar Molding prior to cleft lip repair did not affect breast milk feeding length (P = .72). Relative to patients with cleft lip and palate, patients with isolated cleft lip had a breast milk feeding odds ratio of 1.71. CONCLUSION: We present breast milk feeding in the North American cleft population. Although still lower than the noncleft population, breast milk feeding with regards to initiation rate, length of time, and proportion of total diet is significantly higher than previously reported.

Oral Health-Related Quality of Life and Self-Rated Speech in Children With Existing Fistulas in Mid-Childhood and Adolescence.

OBJECTIVE: To report the associations of oro-nasal fistulae on the patient-centered outcomes oral health-related quality of life and self-reported speech outcomes in school aged-children. DESIGN: Prospective, nonrandomized multicenter design. SETTING: Six ACPA-accredited cleft centers. PARTICIPANTS: Patients with cleft palate at the age of mixed dentition. INTERVENTIONS: None. MAIN OUTCOME MEASURES: Prevalence of fistula and location of fistula (Pittsburgh Classification System). Patients were placed into one of three groups based on the following criteria: alveolar cleft present, no previous repair (Group 1); alveolar cleft present, previously repaired (Group 2); no congenital alveolar cleft (Group 3). Presence of fistula and subgroup classification were correlated to oral health-related quality of life (Child Oral Health Impact Profile [COHIP]) and perceived speech outcomes. RESULTS: The fistula rate was 5.52% (62 of 1198 patients). There was a significant difference in fistula rate between the three groups: Group 1 (11.15%), Group 2 (4.44%), Group 3 (1.90%). Patients with fistula had significantly lower COHIP scores (F1,1188 = 4.79; P = .03) and worse self-reported speech scores (F1,1197 = 4.27; P = .04). Group 1 patients with fistula had the lowest COHIP scores (F5,1188 = 4.78, P =.02) and the lowest speech scores (F5,1188 = 3.41, P = .003). CONCLUSIONS: Presence of palatal fistulas was associated with lower oral health-related quality of life and perceived speech among youth with cleft. The poorest outcomes were reported among those with the highest fistula rates, including an unrepaired alveolar cleft.

Basal View Reference Photographs for Nasolabial Appearance Rating in Unilateral Cleft Lip and Palate.

The Asher-McDade system is a 5-point ordinal scale frequently used to rate the components of nasolabial appearance, including nasal form and nasal symmetry, in unilateral cleft lip and palate. Although reference photographs illustrating this scale have been identified for the frontal and right profile view, no reference photographs exist for the basal view. The aim of this study was to identify reference photographs for nasal form and nasal symmetry from the basal view to illustrate this scale and facilitate its use. Four raters assessed nasolabial appearance (form and symmetry) on basal view photographs of 50 children (average age 8 years) with a repaired cleft lip. Intraclass correlation coefficients show fair to moderate inter-rater reliability. Cronbach α indicated strong agreement between raters (0.77 nasal form; 0.78 nasal symmetry; 0.80 overall), along with low duplicate measurement error and strong internal consistency between the measures. The photographs with the highest agreement among raters were selected to illustrate each point on the 5-point scale for nasal form and for nasal symmetry, resulting in the selection of 10 reference photographs. The basal view reference photograph set developed from this study may complement existing reference photograph sets for other views and facilitate rating tasks.
