Palatal relaxing incisions versus nasopharyngeal relaxing incisions in Palatoplasty.

Bone denudation after conventional relaxing incisions could be a critical factor in inhibiting maxillofacial growth. To address this, alternative relaxing incisions were designed. Thus, this study aimed to compare the effectiveness of palatal relaxing incisions versus nasopharyngeal relaxing incisions in enhancing postoperative outcomes. A retrospective cohort study was conducted, involving a total of 120 patients divided into three groups: 40 patients have received modified Furlow palatoplasty with nasopharyngeal relaxing incisions (M.F + N.P.I palatoplasty), and 40 patients who received modified Furlow palatoplasty with palatal relaxing incisions (M.F + P.R.I palatoplasty). The other 40 patients received original Furlow palatoplasty without relaxing incisions (F palatoplasty). Data collected included gender, cleft type, cleft width, age at repair, velopharyngeal function, presence of palatal fistula, and follow-up. The chi-square test compared frequencies of sex, cleft type, postoperative fistula, and velopharyngeal outcomes across groups. The Mann-Whitney and independent t-tests compared mean values, with statistical significance set at p < 0.05. The mean age at repair was similar across groups, with follow-up periods ranging from 5 to 11 years. No significant differences were found among the M.F + N.P.I and M.F + P.L.I groups regarding gender, cleft type, cleft width, and age at repair. However, the F group had a significantly narrowest cleft width compared to the other groups. Postoperative outcomes showed no significant differences in velopharyngeal function among the three groups, but the F group had a significantly higher rate of palatal fistula (32.5%) compared to the M.F + P.L.I (10%) and M.F + N.P.I (7.5%) groups. A comparison of the two modified Furlow techniques revealed no significant differences in velopharyngeal closure rates or the incidence of velopharyngeal insufficiency and persistent palatal fistula across different Veau classifications. While both incisions showed similar impacts on palatoplasty outcomes, palatal relaxing incisions may expose more bone and pose a higher risk of secondary healing issues. Therefore, nasopharyngeal relaxing incisions are recommended as an effective and potentially preferable technique in palatoplasty whenever feasible. The current study suggests that, whenever feasible, nasopharyngeal relaxing incisions are advised as an effective and potentially superior technique in palatoplasty.

Longitudinal Speech and Fistula Outcomes Following Primary Cleft Palate Repair at a Single Institution

Introduction Fistula formation and velopharyngeal insufficiency (VPI) are complications of cleft palate repair that often require surgical correction. The goal of the present study was to examine a single institution's experience with cleft palate repair with respect to fistula formation and need for surgery to correct velopharyngeal dysfunction. Methods Institutional review board approval was obtained. Patient demographics and operative details over a 10-year period were collected. Primary outcomes measured were development of fistula and need for surgery to correct VPI. Chi-square tests and independent t tests were utilized to determine significance (0.05). Results Following exclusion of patients without enough information for analysis, 242 patients were included in the study. Fistulas were reported in 21.5% of patients, and surgery to correct velopharyngeal dysfunction was needed in 10.7% of patients. Two-stage palate repair was associated with need for surgery to correct VPI (P = 0.014). Furlow palatoplasty was associated with decreased rate of fistula formation (P = 0.002) and decreased need for surgery to correct VPI (P = 0.014). Conclusion This study reiterates much of the literature regarding differing cleft palate repair techniques. A 2-stage palate repair is often touted as having less growth restriction, but the present study suggests this may yield an increased need for surgery to correct VPI. Prior studies of Furlow palatoplasty have demonstrated an association with higher rates of fistula formation. The present study demonstrated a decreased rate of fistula formation with the Furlow technique, which may be due to the use of the Children's Hospital of Philadelphia modification. This study suggests clinically superior outcomes of the Furlow palatoplasty over other techniques.

28. Comparison of Furlow and Straight Line Repair Techniques on Transverse Dental Arch Dimensions and Extent of Orthodontic Intervention

PURPOSE: While the Furlow and straight line repair are the most commonly performed palatoplasty techniques, studies have advocated for the Furlow technique as it provides an increase in palatal lengthening. However, the Furlow technique’s impact on the transverse axis of the dental arch has yet to be explored. This study aims to compare the impact of the Furlow and straight line repair techniques on the transverse dental arch dimensions and the extent for postoperative orthodontic interventions. METHODS: A retrospective chart review of patients with cleft palate with or without a cleft lip at an urban pediatric medical center receiving care from senior surgeons between 1997-2022 was completed. Variables including cleft characteristics, repair type, and orthodontic evaluation and interventions were collected. Patients undergoing straight line repairs (SLR) were compared to those undergoing Furlow palatoplasty. Data were analyzed using Wilcoxon and Chi-Squared analyses in R Studio 4.2.1. RESULTS: Of 1,552 patients with cleft lip and palate deformities, 53% underwent Furlow repair and 47% underwent SLR. SLR was associated with increased rates of maxillary narrowing (orthodontist reported) when compared to Furlow repairs (47% vs 33%, p=.013). Additionally, patients undergoing SLR demonstrated higher rates of orthodontic transverse palatal expansion compared to the Furlow cohort (45.88% vs 30.19%, p=.002). Sub-analysis by cleft type demonstrated that this relationship was only maintained in Veau IV clefts and not in Veau I-III, where the repair technique did not influence rates of transverse palatal expansion. CONCLUSION: This data associates SLR with increased prevalence of maxillary narrowing and transverse palatal expansion, particularly in veau IV cleft phenotypes. A potential explanation is that the greater width of bilateral clefts may require more extensive dissection, contributing to increased scarring and transverse maxillary hypoplasia when completing straight line repair. When counseling patients and families on benefits of various repair techniques, Veau IV clefts should be advised that more extensive orthodontic interventions may be required with straight line repair techniques.

D23. Quarter Century Review of Velopharyngeal Insufficiency Rates between Palatoplasty Techniques among Patients with Robin Sequence

PURPOSE: Children with Robin sequence (RS) have wide U-shaped cleft palates. Following primary palatoplasty, RS patients have high rates of velopharyngeal insufficiency (VPI), often requiring speech-correcting surgery. This study compares VPI rates between palatoplasty techniques among the RS population. METHODS: A retrospective review of patients with isolated RS without concomitant syndromes from 1997-2022 was completed. Clinical and operative data were collected. Surgical techniques were performed by multiple senior surgeons and were categorized as Furlow double-opposing Z-plasty or straight-line palatoplasty. The primary outcome is surgical VPI rates. RESULTS: Upon review, 91 patients were identified to have isolated RS, of which 79 had a concomitant cleft palate. Overall surgical VPI rate was 11.4%. Follow-up time was 6.3±4.8 years (Furlow) and 4.2±4.0 years (straight-line; p=0.0593). Excluding patients with less than two years of follow-up, 35.7% (15/42) of Furlow patients had clinically diagnosed VPI compared to 11.8% (2/17) of the straight-line cohort (p=0.066). No patients in the straight-line cohort required speech-correcting surgery. The Furlow cohort had higher surgical VPI rates (21.4% vs. 0.0%; p=0.038) compared to straight-line. Upon Kaplan-Meier analysis, the 5-year surgical VPI rate was 11.6% and 0.0% for the Furlow and straight-line cohorts, respectively (p= 0.066). CONCLUSION: Our findings suggest the Furlow technique resulted in higher surgical VPI rates than straight-line repair among our RS patients. Though the Furlow technique offers palatal lengthening, this technique may compromise velum function in this wide cleft RS population.

Evaluation of Postoperative Outcomes in Two Cleft Palate Repair Techniques without Relaxing Incisions.

A modified palatoplasty was established by incorporating the designs of both Sommerlad and Furlow techniques in addition to a novel incision on the medial pterygoid plate's surface, named the Sommerlad-Furlow modified technique. Thus, this study aimed to evaluate the clinical and functional outcomes of the Sommerlad-Furlow modified technique against an accepted standard, the Furlow technique. A retrospective review was conducted for 212 consecutive nonsyndromic cleft palate patients who underwent Sommerlad-Furlow ( n = 106) and Furlow ( n = 106) repairs without relaxing incision on the hard palate between 2011 and 2016. The success of surgical procedures was estimated by the rate of postoperative fistula, speech outcomes, and velopharyngeal insufficiency (VPI)-related quality of life. The demographic and surgical data, including sex, age, cleft type, cleft width, and follow-up period were recorded. There was no statistically significant difference between the two treatment groups regarding demographic and surgical data, except the cleft width ( P < 0.001). The incidence of the fistula was 7.5% and 6.6% after the Sommerlad-Furlow and Furlow procedures, respectively. The two groups showed no significant differences in speech outcomes, and adequate velopharyngeal function was found in 84% and 82.1% in Sommerlad-Furlow and Furlow procedures, respectively. Besides, the rate of severe VPI was slightly lower in Sommerlad-Furlow (0.9%) than in Furlow (2.8%) procedures. Moreover, an adequate VPI-related quality of life was found in 80.4% of the Sommerlad-Furlow group and 78.6% of the Furlow group. The Sommerlad-Furlow technique has obtained acceptable postoperative outcomes and could be a choice for cleft palate repair, especially in wider clefts. Therapeutic, III.

Does Early Two-stage Palatoplasty Using the Modified Furlow Technique Lead to Favorable Maxillofacial Growth?

Influence of patient-related factors on intraoperative blood loss during double opposing Z-plasty Furlow palatoplasty and buccal fat pad coverage: A prospective study.

BackgroundSurgical procedures including palatoplasty have a risk for complications. The aim of this study was to investigate the intraoperative and early postoperative blood loss using the buccal fat pad (BFP) during cleft lip and/or cleft palate (CL/P) surgery. Material and MethodsThis prospective study included a total of 109 patients with cleft palate (CP) during a three-month period of treatment at Hasanuddin University Dental Hospital (permanent center) and charity trips in rural parts of Eastern Indonesia. All patients were treated with DOZ Furlow technique combined with BFP graft. Before and after surgery, the total amount of intraoperative blood loss was calculated by measuring the weight differences of the gauze swabs that were used to control the surgical bleeding followed by a complete blood count at three days postoperatively. ResultsThe difference in the amount of blood loss based on age categories in charity groups was found to be significant (P<0.05). Overall, we found that high body weight and operation time significantly contributed to increased blood loss (P<0.05). Conclusions Weight and operative time can contribute to more blood loss during palatoplasty. Key words:Buccal fat pad, complication, cleft lip, cleft palate, palatoplasty.

Quantitative Evaluation of Palatal Lengthening After Cleft Palate Repair When a Buccal Flap Is Routinely Combined With Furlow's Z-Plasty.

The use of a buccinator myomucosal flap in combination with Furlow's Z-plasty during primary and secondary palatal repairs has been proposed by many authors to overcome some of the limitations of Furlow's technique. However, there have been no studies that quantitatively measured the effective palatal lengthening when the buccal flap is added. The buccal flap is routinely used during primary palate repair in order to fill the gap between the hard palate and reoriented palatal muscle sling. The soft palatal length was measured in the midline from the posterior edge of the hard palate to the base of the uvula. All patients were measured before starting the surgery and just after palatal closure in the standard position for cleft palate repair. Seventy-three patients with cleft palate who were candidates for primary repair were included. The mean age at the time of operation was 11.4 ± 3.5 months. The mean preoperative palatal length was 21.36 ± 3.529 mm, whereas the mean postoperative palatal length was 29.64 ± 4.171) mm. The mean palatal length change was 8.29 ± 2.514 mm (P < 0.000). The Combined use of a buccinator myomucosal flap with modified Furlow's Z-plasty in primary cleft palate repair has proven effective for palatal lengthening and achieved tensionless closure without the need for relaxing incision. It also provided a pliable soft tissue attachment of the palatal muscles to the hard palate allowing for better muscle function and mobility.

Furlow Palatoplasty: Should We Also Focus on the Size of the Nasopharynx?

(1) To determine the incidence rate of velopharyngeal dysfunction (VPD) according to 7 speech criteria post-Furlow palatoplasty. (2) To find an anatomical measurement of the cleft palate (or combination of measurements) associated with the occurrence of VPD. Retrospective cohort study. Fifty-six patients with cleft palate ± cleft lip underwent palatoplasty with the Furlow technique at the age of 10 months. Pre-and post-palatoplasty cleft palate measurements were collected during the procedure. Three blinded speech-language pathologists (SLPs) retrospectively scored the patients from the chart data at age 4. Student t test and receiver operating characteristic curve analysis were used to evaluate the association and predictive capacity between cleft measurements and parameters (M&P) with all VPD criteria. The SLPs found an incidence of VPD according to 7 criteria: hypernasality (11%), audible nasal emission (4%), nasal rustle (14%), compensatory errors (4%), impairment of speech understandability (7%), and impairment of speech acceptability (16%). The SLPs recommended a secondary surgical procedure in 5 patients (9%). A statistically significant association was found between, respectively, 17 and 5 M&P and the occurrence of compensatory errors and audible nasal emission. Our data suggest that the length of the cleft, the cleft area, and the postoperative transversal size of the nasopharynx are the best indicators of the future positivity of VPD criteria. The size of the postoperative transverse nasopharyngeal area during the primary cleft palate procedure may become the focus of the next generation of cleft surgeons to reduce the incidence of VPD.

Evaluation of fistula rates in three cleft palate techniques without relaxing incisions

The aim of the present study was to investigate the incidence of postoperative fistula formation from a hybrid cleft palate repair compared to that from two well-established techniques.We performed a modified technique, Sommerlad-Furlow (SF), which combined the repositioning of the levator veli palatini muscles as described by Sommerlad with the double opposing Z-plasty of Furlow to lengthen the soft palate. A retrospective cohort study was conducted to evaluate patients who underwent cleft palate repair utilizing SF, Sommerlad, or Furlow techniques with the incidence of palatal fistula as the target endpoint.A total of 1,164 patients were included in the present study and underwent the following techniques: 603 cases with SF, 244 cases with Furlow, and 317 cases with Sommerlad. In addition to not requiring relaxing incisions, SF advantages included a consistently lower fistula rate compared to that of the Sommerlad technique, as well as the lowest fistula rate in patients with both hard and soft palate clefts without a cleft lip (OR:2.62 95% CI: 1.35, 5.09). However, the differences among the three techniques did not reach statistical significance in terms of a bilateral or unilateral cleft lip/palate, or in patients with a soft palate only or a submucosal cleft palate(OR: 2.22,95% CI:0.77, 6.37).Based on the results of our study, the Somerlad-Furlow technique should be preferred whenever possible.

Evaluation of Results of the Furlow’s Modified Technique in the Management of Cleft Palate in the Teaching Hospital of Conakry

Introduction: Cleft palate (CP) is a congenital dysmorphosis that results from a failure of the palatal processes of the maxillary buds and nasal septum to merge. The objectives of this study were to determine the frequency of complications of the modified Furlow technique and to evaluate its anatomical and functional outcomes. Materials and Method: This was a retrospective study that took place over a period of 4 years (from January 1st, 2015 to December 31th, 2018) in the Department of Odontostomatology and Maxillofacial Surgery at the National Hospital of Donka (Conakry, Guinea). Data retrieval consisted of records from patients operated on for cleft palate according to Furlow’s modified technique only. The operative technique consisted of marginal incisions of the cleft according to the technique of the double Z-plasty of Furlow. Subsequently, the defect created between the 2 flaps and the anterior edge of the cleft was filled by two fat masses of Bichat sutured to each other with Vicryl 3-0. Four years after surgery, the patients were recalled for an evaluation of the anatomical and functional results. Results: 13 patients underwent surgical loading according to the modified Furlow technique. The average age of the patients was 6.9 years with an age range of 7 months and 17 years. Females were the most affected, with 61.54% of cases and a sex ratio of 0.62. The primary repair rate was 84.61% of cases. Immediate operative follow-up was simple with epithelialization of the flaps in all patients. Four (4) years after the surgeries, 12 patients were reevaluated (92.30%), among them one case (8.33%) of fistula complication was noted. The mobility of the veil and the phonation were good in 85.71% and 60% respectively. Articular disorders with nasonation were found in 2 patients (16.67%). Swallowing was normal in 85.72% of cases. Conclusion: The modified Furlow technique is an important contribution to cleft palate surgery significantly reducing the occurrence of postoperative complications. However, the delay of the surgical operation remains a real obstacle for obtaining a normal phonation.

Influence of surgical technique and timing of primary repair on interarch relationship in UCLP: A randomized clinical trial.

To compare dental arch relationships in children with unilateral cleft lip and palate (UCLP) between two surgical techniques for repair of cleft lip/palate and two ages of palate repair. Dental models were taken for a group of 448 subjects at a mean age of 7years and were evaluated by means of the Goslon Yardstick. The patients studied consisted of an initial group of 673 infants with complete UCLP randomized into 8 study groups according to lip repair procedures (Millard versus Spina techniques); palate repair procedures (von Langenbeck versus Furlow techniques); and palate repair timing (early: 9 to 12months versus late: 15-18months). Four surgeons performed all surgeries. Dependent variables included the following: lip repair technique, palate repair technique, age at time of palate repair and surgeon; with sex as an independent variable. The data were analysed using a general linear model (P<.05). There were no significant differences for occlusal index scores as a function of lip or palate surgical technique, palatal repair timing and sex. Significant differences were found for occlusal index scores as a function of the surgeon. Dental arch relationships were not influenced by lip and palatal repair techniques or patient age at palatal repair. The surgeon was the major factor that influenced the dental arch relationship outcome.

Buccal fat pad in cleft palate repair- An institutional experience of 27 cases

ObjectivesThe purpose of this paper is to consider the anatomical basis and surgical technique along with the utility of buccal fat pad (BFP) for the reconstruction in cleft lip and palate patients. MethodsWe reviewed 27 cases of CLAP treated with BFP over three year period in our institution which included 2 cases of primary palatoplasty & 25 cases of secondary palatoplasty. Inclusion criteria consisted of patients operated by a single surgeon with a minimum follow up of 2yrs. Exclusion criteria included all syndromic cleft lip and palate patients. Predictor variables recorded were demographic characters, follow up period, type of cleft, type of surgical procedure, site & dimension of the fistula. Outcome variables of the study were post-operative fistula formation, post-operative hemorrhage & speech assessment. ResultsThe study included 8 female & 19 male patients with mean age group 3.75 ± 1.75yrs. Cleft of soft palate & Lt. CLAP were the most common type of cleft. The surgical technique used was: BFP with V–Y pushback palatoplasty for primary palate repair, BFP with Furlow's technique for VPI correction, and BFP in conjugation with rotation flap, straight-line closure or redohardpalatoplasty for fistula closure. All cases showed satisfactory healing with favorable speech assessment outcomes for 18 patients (67%). ConclusionBFP along with other types of flap is the choice of treatment in cases of moderate defect owing to its favorable anatomic location & high vascularity. The size limitation of the BFP must be known to permit a successful outcome.

Determining postoperative outcomes after cleft palate repair: A systematic review and meta-analysis

BackgroundA lack of high-level evidence exists on the outcomes of different cleft palate repair techniques. A critical appreciation for the complication rates of common repair techniques is paramount to optimize cleft palate care. MethodsA literature search was conducted for articles on the measurement of fistula and velopharyngeal insufficiency (VPI) rates following cleft palate repair. Study quality was determined using validated scales. The heterogeneity between studies was evaluated using the I2 statistic. Random-effect model analysis and forest plots were used to report pooled relative risks (RRs) with 95% confidence intervals for treatment effect. P-values of 0.05 were considered statistically significant. ResultsOf 2386 studies retrieved, 852 underwent screening and 227 met inclusion criteria (130 studies (57%) on fistulas and 122 studies (54%) on VPI). Meta-analyses were performed using 32 studies. The Furlow technique was associated with less postoperative fistulae than the von Langenbeck and Veau/Wardill/Kilner techniques (RR = 0.56 [0.39–0.79], p < 0.01 and RR = 0.25 [0.12–0.52], p < 0.01, respectively). One-stage repair was associated with less fistulae compared to two-stage repair (RR = 0.42 [0.19–0.96], p = 0.04). The Furlow repair was also associated with a less VPI than the Bardach palatoplasty (RR = 0.41 [0.23, 0.71], p < 0.01), and the one-stage repair was associated with a reduction in VPI rates compared to two-stage repair (RR = 0.55 [0.32, 0.95], p = 0.03). ConclusionThe Furlow repair is associated with less risk of fistula formation than the von Langenbeck and Veau/Wardill/Kilner techniques and less VPI compared to the Bardach repair. One-stage repair is associated with less risk of fistula formation and VPI than two-stage repair.

Analysis of Arch Widths in Patients With Isolated Pierre Robin Sequence.

To compare arch widths of patients with isolated Robin sequence (IRS) operated using modified von Langenbeck technique and modified Furlow double-opposing z-plasty. Retrospective, transversal study. Hospital of Rehabilitation of Craniofacial Anomalies, University of São Paulo, Bauru, Brazil. Three groups of patients were analyzed. Group VL comprised 30 patients with IRS operated by von Langenbeck technique (mean age of 8.1 years); group FL included 30 patients with IRS operated by Furlow technique (7.6 years); and the control group included 30 noncleft patients with class I occlusion (7.4 years). The palate repair was performed between 1.0 and 1.7 years of age in both study groups. Transversal measurements of maxillary and mandibular arches were performed digitally on 3D digital models. The intergroup comparison was performed using analysis of variance and Tukey test. An independent t test was used to compare the complete and incomplete types of cleft in both study groups. The level of significance was 5%. No statistically significant difference was found between the VL and FL groups for maxillary and mandibular arches. However, both groups showed decreased transversal dimensions compared with the control group (P < .01) for both dental arches. No differences for arch widths were observed for complete or incomplete palatal clefts. No influence of palate repair techniques was observed in the transversal arch widths in patients with IRS. Children with IRS operated for palate repair showed constriction of the maxillary and mandibular dental arches compared with noncleft children regardless the palatal cleft extension.

Size of Velopharyngeal Structures After Primary Palatoplasty.

To describe and compare measures of velar length, velar thickness, and depth of the nasopharynx between two groups of patients with velopharyngeal dysfunction after primary palatoplasty: one received the modified Langenbeck procedure and the other the Furlow procedure. Comparative study involving a convenience sample of videofluoroscopic films established prospectively. Surgeries and videofluoroscopic assessments were conducted at a craniofacial center. Exams from 90 participants were used: 27 (30%) operated with Furlow and 63 (70%) with Langenbeck. Three speech-language pathologists (SLPs) traced the images of the velopharyngeal port to determine the measures of interest. Intrajudge agreement for the SLPs ranged between 0.85 and 0.53, while interjudge agreement ranged between 0.44 and 0.51. The overall measure of velar length was significantly larger (P = .042) for the Furlow group (mean = 26.5) than the Langenbeck group (mean = 24.2 mm). There was no significant difference in velar thickness or depth of the nasopharynx between the two procedures. Although no significant difference was found between the current findings and Subtelny's norms for length, thickness, and depth, the patients presented with an overall depth:length ratio (0.89) significantly greater than Subtelny' ratio (P = .025). The findings of this study confirmed the hypothesis that patients who underwent surgery with the Furlow technique may present with significantly longer velums than patients who underwent surgery with the Langenbeck procedure. Information regarding velopharyngeal morphology was predictive of velopharyngeal dysfunction for speech for 80% of the participants and can be useful in documenting outcome of treatment.

Incidence of Secondary Surgery after Modified Furlow Palatoplasty: A 20-Year Single-Surgeon Case Series.

Objective To determine the occurrence of velopharyngeal insufficiency (VPI) requiring surgery and fistula repair after primary palatoplasty using a "modified" Furlow technique. Study Design Case series with chart review. Setting Academic multidisciplinary cleft and craniofacial center. Subjects and Methods Children younger than 18 years at presentation, with unrepaired cleft palate, with or without cleft lip, including submucous clefts, who underwent palatoplasty were included. No cleft patients having primary repair were excluded. All operations were conducted by a single surgeon from March 1994 through December 2013. Charts were reviewed for demographics, cleft type, genetic syndrome, operations performed, and complications, including VPI and oronasal fistula. Results In total, 312 consecutive patients underwent primary palatoplasty (160 [51.3%] male) with a median age of repair of 0.95 (range, 0.47-17.6) years and followed for 6.49 (range, 4.0-20.2) years. Robin sequence was diagnosed in 109 (34.9%), 104 (33.4%) had alveolar clefts, and 27 (8.7%) had concomitant gingivoperiosteoplasty. A modified Furlow was performed in 289 (92.6%). Overall, 16 (5.1%) required subsequent pharyngeal flap for VPI, and 48 (15.4%) required oronasal fistula repair. Veau class II had higher pharyngeal flap rates ( P = .033). Fistula repair was lower in Veau I ( P < .001) but higher in Veau II ( P < .001) and IV ( P = .002). Older age ( P = .034) and Robin sequence ( P = .017) were associated with higher rates of oronasal fistula repair. Conclusions The modified Furlow palatoplasty yields acceptable rates of secondary surgery for VPI without selection based on cleft width. While our oronasal fistula repair rate is high, it is concordant with previous reports and is likely related to our rare use of lateral relaxing incisions.

Cephalometric Outcomes of Maxillary Expansion and Protraction in Patients With Unilateral Cleft Lip and Palate After Two Types of Palatoplasty.

To clarify the differences in the long-term effects of maxillary expansion (ME) and protraction (MP) in patients with complete unilateral cleft lip, alveolus, and palate (UCLP) undergoing two types of palatoplasty. Retrospective longitudinal study. Institutional study. Thirty-eight patients with UCLP treated at Osaka University Dental Hospital, Japan, were divided into two groups: 19 patients were treated using Wardill-Kilner push-back palatoplasty (PB), and 19 patients were treated with early two-stage palatoplasty according to the modified Furlow technique (ETS). All patients exhibited a short maxilla at the initial orthodontic visit and were treated with ME using a quad helix appliance and MP with a face mask. Lateral cephalometric data recorded in the initial stage were compared with those obtained at the end of treatment. The dentoskeletal features and facial soft tissue profile were evaluated before and after orthodontic treatment. The variation and rate of change during treatment were also calculated. The Mann-Whitney U test was used for the statistical analyses. The ETS group showed significantly greater SNA, SNB, and U1-Pp angles and smaller SN-Mp angles than the PB group after face mask treatment. The variation in the anteroposterior length of the maxilla during treatment was significantly greater in the ETS group than in the PB group. Maxillary protraction was more efficiently accomplished in the patients with UCLP after early two-stage palatoplasty compared with push-back palatoplasty.

Influence of Different Palatoplasties on the Facial Morphology of Early Mixed Dentition Stage Children With Unilateral Cleft Lip and Palate.

To compare the maxillofacial morphology in the early mixed dentition phase between two patient groups with unilateral cleft lip, alveolus, and palate who underwent different types of palatoplasty. Cross-sectional study. An institutional study. Seventy-one patients with unilateral cleft lip and palate (UCLP) treated at Osaka University Dental Hospital, Japan, were divided into two groups: 33 patients were treated by early two-stage palatoplasty by the modified Furlow Technique (ETS), and 38 patients were treated by one-stage Wardill-Kilner push-back palatoplasty (PB). Intergroup comparisons were performed. The dental, skeletal, and soft-tissue features were evaluated. For intergroup comparisons, Mann-Whitney U test was used for the statistical analyses. No significant differences existed between the ETS and PB groups regarding the skeletal features except for the mandibular ridge height. Meanwhile, the upper central incisor and upper lip of the ETS group showed a more anterior position than those in the PB group. Early two-stage Furlow palatoplasty leads to more protruded upper lip, providing more anteriorly positioned upper incisors compared with PB, at least at the early mixed dentition stage.
