Comparison of modified Furlow palatoplasty using small double-opposing Z-plasty and conventional Furlow palatoplasty: A long-term outcome study.

BACKGROUND: The aim of palatoplasty is to create a functional palate to achieve normal speech, while minimizing post-operative complications. This study aimed to compare the long-term outcomes of modified Furlow palatoplasty using small double-opposing Z-plasty (small-DOZ) and conventional Furlow palatoplasty (conventional-DOZ) performed in a single center. METHODS: A retrospective review of consecutive patients who underwent Furlow palatoplasty between May 2007 and March 2014 was executed. Non-syndromic patients subjected to palatoplasty prior to 24 months of age and followed-up until at least 9 years of age were included. RESULTS: A total of 196 small-DOZ and 280 conventional-DOZ palatoplasty patients were included in this study. Overall, 14 patients (2.9%) developed oronasal fistula, and 40 patients (8.4%) received velopharyngeal insufficiency (VPI) surgery. In comparisons, oronasal fistula rate was significantly higher in conventional-DOZ (0.5% vs. 4.6%, p = 0.01), and the VPI prevalence was not significantly different (9.2% vs. 7.9%, p = 0.62). Patients who developed fistula had a significantly higher likelihood of developing VPI than patients without oronasal fistula (50.0% vs. 7.1%, respectively; p < 0.01), with an odds ratio of 13.0. CONCLUSION: Both modalities of palatoplasty yielded commendable velopharyngeal function in the long-term follow-up. The small-DOZ with reduced tension lowered the risk of oronasal fistula.

Stability between single and segmental maxillary osteotomies in bimaxillary surgery for cleft-associated class III deformity: a CBCT study.

OBJECTIVE: Segmental Le Fort I osteotomy through the cleft is a common strategy to narrow the alveolar cleft in adults. This study compared skeletal stability between single and segmental Le Fort I osteotomies in patients with unilateral cleft lip and palate (UCLP). MATERIALS AND METHODS: This retrospective analysis examined 45 adults with complete UCLP-associated class III deformities who underwent bimaxillary surgery with either single (n = 30) or segmental (n = 15) Le Fort I advancement. Cone beam computed tomography (CBCT) scans of the facial skeleton were acquired before surgery, 1-week postsurgery, and at follow-up. Measures of landmarks from the CBCT images for the two treatment groups were compared for translation (left/right, posterior/anterior, superior/inferior) and rotation (yaw, roll, pitch). RESULTS: Postsurgery, the downward movement of the maxilla was larger in the segmental group than the single group. At follow-up, the maxilla moved backward in both groups, and upward in the segmental group. The mandible moved forward and upward and rotated upward in both groups. The amount of upward movement and rotation was larger in the segmental group than the single group. CONCLUSIONS: Two years after bimaxillary surgery in patients with UCLP-associated class III deformity, greater relapse was found after segmental Le Fort I osteotomies in vertical translation of the maxilla and mandible, and pitch rotation of the mandible compared with single Le Fort I osteotomies. CLINICAL RELEVANCE: The vertical relapse of the maxilla was larger after segmental Le Fort I advancement compared with single Le Fort I advancement in clefts.

Chang Gung Forum: An Exemplary Strategy for Implementing a Multidisciplinary Network of Experts in Craniofacial Anomalies.

INTRODUCTION: The Chang Gung Forum has been dedicated to the care of craniofacial anomalies since 2000. This annual continuing medical education program focuses on orofacial cleft and surgery-first orthognathic surgery by providing up-to-date information and management guidelines. This study explored how the Chang Gung Forum has influenced medical perspectives, decisions, and practices in a multidisciplinary craniofacial team. METHODS: Between 2000 and 2022, 20 Chang Gung Forums have been held. A questionnaire was distributed among 170 attendees who had participated in the forum more than once. The questionnaire collected information on the participants' experiences and levels of satisfaction with the educational program and whether or how it had influenced their clinical practice. RESULTS: Valid responses from 86 attendees (response rate, 50.6%) who had participated more than once were collected and analyzed. The overall satisfaction rate of the Chang Gung Forum based on the respondents' most recent visits was 4.28 ± 0.63 out of 5. Of the respondents, 90.9% acknowledged changes in their clinical practice, with modifications in surgery plans and decisions being the most notable (48.5%). In addition, comprehension increased throughout years of attending the annual forum (P < 0.001). CONCLUSION: The Chang Gung Forum has contributed markedly to the community of congenital craniofacial anomalies. The program will continue providing updated information and influencing the clinical decision-making of health care professionals.

Surgery-First Orthognathic Approach for Correction of Dentofacial Deformity in Unilateral Cleft Lip and Palate.

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

Surgical occlusion setup and skeletal stability of correcting cleft-associated class III deformity using surgery-first bimaxillary surgery.

BACKGROUND: This study aimed to assess the three-dimensional (3D) quantitative characteristics of the surgical occlusion setup in surgery-first cleft orthognathic surgery, and to evaluate its influence on post-surgical skeletal stability. METHODS: This prospective study was comprised of 35 patients with unilateral cleft lip and palate and class III deformity who consecutively underwent two-jaw surgery with surgery-first approach. Digitized dental models were analyzed to quantify the 3D characteristics of the final surgical occlusion setup. Cone-beam computed tomography was used to measure the 3D surgical skeletal movement and post-surgical skeletal stability. The correlation between skeletal stability and surgical occlusal contact or surgical skeletal movement was also evaluated. RESULTS: The surgical occlusion setup had a large incisor overjet and positive overbite, and buccal cross bite and open bite on second molars. Occlusal contact on three segments was present in 51.4% of the patients, and the average number for tooth contact was 4.3 teeth. No correlation was found between maxillary or mandibular stability and surgical occlusal contact. However, a significant correlation was found between maxillary and mandibular stability and the surgical skeletal movement. CONCLUSIONS: The surgical occlusion for correction of cleft-associated class III deformity using the surgery-first approach was characterized with large overjet and positive overbite, and posterior cross bite and open bite. On average, there was occlusal contact on four to five teeth; half of surgical occlusion setups had contact on three segments. The post-surgical skeletal stability was not related to the surgical occlusal contact but to the surgical skeletal movement.

Outcomes of alveolar cleft repair in complete cleft lip and palate after tertiary gingivoperiosteoplasty and segmental Le Fort I osteotomy.

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

Long-term treatment outcome of patients with complete bilateral cleft lip and palate: a retrospective cohort study.

BACKGROUND: Patients with cleft lip and palate have functional and esthetic impairment and typically require multiple interventions in their life. Long-term evaluation following a treatment protocol, especially for patients with complete bilateral cleft lip and palate (BCLP), is important but was rarely reported in the literature. PATIENTS AND METHODS: A retrospective review was conducted on all patients with complete BCLP born between 1995 and 2002 and treated at our center. Inclusion criteria were having adequate medical records and receiving continuous multidisciplinary team care at least until 20 years of age. Exclusion criteria were lack of regular follow-up and congenital syndromic abnormalities. The medical records and photos were reviewed, and facial bone development was evaluated using cephalometric analysis. RESULTS: A total of 122 patients were included, with a mean age of 22.1 years at the final evaluation in this study. Primary one-stage cheiloplasty was performed in 91.0% of the patients, and 9.0% underwent two-stage repair with an initial adhesion cheiloplasty. All patients underwent two-flap palatoplasty at an average of 12.3 months. Surgical intervention for velopharyngeal insufficiency was required in 59.0% of patients. Revisional lip/nose surgery was performed in 31.1% during growing age and in 64.8% after skeletal maturity. Orthognathic surgery was applied in 60.7% of patients with retruded midface, of which 97.3% underwent two-jaw surgery. The average number of operations to complete the treatment was 5.9 per patient. CONCLUSION: Patients with complete BCLP remain the most challenging group to treat among the cleft. This review revealed certain suboptimal results, and modifications have been made to the treatment protocol. Longitudinal follow-up and periodic assessment help to establish an ideal therapeutic strategy and improve overall cleft care.

Aesthetic Outcome of Primary Rhinoplasty of Saddle Nose Deformity in Naso-Orbital Ethmoidal Fractures in Asian Patients.

BACKGROUND: Saddle nose deformity following naso-orbital ethmoidal (NOE) fractures remain a challenging problem for the reconstructive surgeon. Early reduction and internal fixation allow for fracture stabilization but is unable to address the problem of the depressed nasal dorsum, especially after soft tissue shrinkage. The aim of this study is to evaluate the outcome of primary rhinoplasty in patients with NOE fractures. MATERIALS AND METHODS: From 2016 to 2019, 9 patients presented to our department with NOE fractures complicated by saddle nose deformity underwent primary nasal reconstruction at the time of their fracture fixation. Life size (1:1) frontal and lateral postoperative photographs were taken. Three objective measurements were made, including the nasofrontal angle, tip projection, and radix projection. These measurements were compared between normal persons (group 1), preoperative patients (group 2), and postoperative patients (group 3). Nose aesthetic assessment was carried out via a panel assessment using a Visual Analog Scale of 5. Patient satisfaction was further assessed subjectively by the patient themselves using the Visual Analog Scale. RESULTS: When comparing group 3 to 2, a significant reduction in the nasofrontal angles was found with an accompanying increase in the radix and tip projection ( P <0.05). No statistical significance between normal persons and postprimary rhinoplasty patients was noted between groups 1 and 3. Average patient satisfaction scored 3.86±1.07 compared with 3.63±0.84 by laypersons and 4±0.77 by specialists' panel. CONCLUSION: Primary nasal reconstruction may be an alternative method for achieving optimum results following NOE fractures preventing the development of secondary saddle nose deformity with a shortened nose which may potentially be more difficult to correct.

Symmetry of the Vermillion Height after Modified Rotation-Advancement Cheiloplasty.

(1) Background: This study aimed to determine the postoperative vermillion symmetry between the cleft and non-cleft sides of patients with unilateral cleft lip during the early and late postoperative periods. (2) Methods: 57 patients with complete and 38 with incomplete unilateral cleft lips operated on between 2010 and 2014 were retrospectively evaluated within 1 month (T1), 9 months to 1 ½ years (T2), and more than 4 years (T3). Vermilion heights of the cleft and non-cleft sides were measured from frontal photographs. The Cleft Lip Component Symmetry Index (CLCSI) was used to determine the symmetry of the cleft and non-cleft sides and was then analyzed. (3) Results: Among the 95 patients studied, vermilion height was excessive on the cleft side throughout the three time periods. There was a significant increase in CLCSI from T1 to T2 for both complete and incomplete types, and a significant increase from T1 to T3 only in the incomplete group and no difference from T2 to T3 for both the groups. (4) Conclusions: Even with efforts to obtain a symmetric vermilion height during the primary cheiloplasty, vermilion height excess was noted with time in complete and incomplete cleft types. Secondary revisional vermilion surgery may be performed to achieve symmetry.

Extensive Gingivoperiosteoplasty Versus Secondary Alveolar Bone Grafting in Patients With Complete Bilateral Cleft Lip and Palate During the Mixed Dentition Period: A Retrospective Outcome Analysis.

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

Comparison of stability and outcomes of surgery-first bimaxillary surgery for skeletal class III deformity between unilateral and bilateral cleft lip and palate.

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

Patient satisfaction and quality of life after orthodontic treatment for cleft lip and palate deformity.

OBJECTIVES: Patients with cleft lip-cleft palate (CLP) often require orthodontic treatment, with or without orthognathic surgery. Patient satisfaction is the most important outcome parameter in orthodontic treatment. This study aimed to (1) determine patient satisfaction and quality of life (QoL) after orthodontic treatment and (2) identify associated factors. MATERIAL AND METHODS: This prospective cross-sectional study recruited patients with CLP who had completed orthodontic treatment at a craniofacial center in Taiwan. Participants (N=213) had received treatment for unilateral CLP (n=99), bilateral CLP (n=50), cleft lip and alveolus (n=39), and isolated cleft palate (n=25). Self-report questionnaires evaluated satisfaction with appearance and QoL; multiple regression analysis examined associated factors. Participants' expectations of treatment results were also reported. RESULTS: Participants reported moderate satisfaction with facial appearance and QoL. Satisfaction with treatment was lower or much lower than expected for 13% of participants. Treatment for bilateral CLP was associated with the lowest satisfaction with overall appearance (r = -8.123, P < 0.05); participants who had received orthognathic surgery had the highest satisfaction (r = 5.534, P < 0.05). Treatment for unilateral and bilateral CLP was associated with low QoL for smile (both P < 0.05). CONCLUSIONS: Orthodontic treatment had a positive effect on facial appearance and quality of life in patients with CLP. Type of cleft and orthognathic surgery significantly influenced satisfaction with facial appearance. CLINICAL RELEVANCE: Efforts must be taken to modify treatment strategies for patients with bilateral CLP in order to improve satisfaction with appearance following treatment.

Unilateral Cleft Lip Repair Using the Chang Gung Technique: An Outcome Analysis.

OBJECTIVE: This retrospective study analyzed the outcomes of patients undergoing complete or incomplete unilateral cleft lip repair using the Chang Gung technique. The goal was to compare the symmetry and change of the technique through the measurement of anthropometric points on digital photographs. METHODS: From 2010 to 2016, a total of 274 complete and incomplete cleft lip patients without other craniofacial deformities were included in the study. All included patients had a minimum 1-year follow-up with frontal view photographs taken. The vermilion area, lip width, vermilion height, lateral lip length, lip height, and Cupid's bow width of both cleft and noncleft sides were measured for all patients. The Cleft Lip Component Symmetry Index was used to determine the symmetry of the cleft and noncleft sides in both incomplete and complete cleft groups. RESULTS: A total of 152 complete and 122 incomplete cleft lip patients were included in the study. The mean Cleft Lip Component Symmetry Index values showed that the vermilion area, lip height, and Cupid's bow width were symmetric on both cleft and noncleft sides. Lip width and lateral lip length were noted to be shorter, whereas the vermilion height was thicker on the cleft side than on the noncleft side. Significant differences between the complete and incomplete cleft group measurements were found for lateral lip length and lip height, and complete cleft measurements were shorter than those for incomplete clefts. There were no significant differences in vermilion area, lip width, vermilion height, and Cupid's bow width. CONCLUSIONS: The outcome analysis showed that vermilion height reduction and modifications could be made for both complete and incomplete groups. The complete cleft lip has been found to have a significantly shorter lateral lip length and lip height, reflecting a more severe anatomical soft tissue deficiency in this group. A long-term outcome anthropometric point study may further verify the results of this surgical technique.

Videofluoroscopic Findings as Predictors of Velopharyngeal Insufficiency After Orthognathic Surgery in Patients With Cleft Lip and Palate.

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

Patient-Specific Three-Dimensional Printing Guide for Single-Stage Skull Bone Tumor Surgery: Novel Software Workflow with Manufacturing of Prefabricated Jigs for Bone Resection and Reconstruction.

OBJECTIVE: To describe a novel system workflow to design and manufacture patient-specific three-dimensional (3D) printing jigs for single-stage skull bone tumor excision and reconstruction and to present surgical outcomes of 14 patients. METHODS: A specific computer-aided design/computer-aided manufacturing software and hardware system was set up, including a virtual surgical planning subsystem and a 3D printing-associated manufacturing subsystem. Computed tomography data of the patient's skull were used for 3D rendering of the skull and tumor. The output of patient-specific designing included a 3D printing guide for tumor resection and a 3D printing model of the bone defect after tumor excision. A polymethyl methacrylate implant was fabricated preoperatively and used for repair. RESULTS: The specific 3D printing guide was used to design intraoperative jigs and implants for 14 patients (age range, 1-72 years) with skull bone tumors. In all cases, the cutting jig allowed precise excision of tumor and bone, and implants were exact fits for the defects created. All operative results were successful, without intraoperative or postoperative complications. Postoperative computed tomography scans were obtained for analysis. Postoperative 3D measurement of the skull symmetry index (cranial vault asymmetry index) showed significant improvement of head contour after surgery. CONCLUSIONS: The computer-aided design/computer-aided manufacturing system described allows definitive preoperative planning and fabrication for treatment of skull bone tumors. Apparent benefits of the method include more accurate determination of surgical margins and better oncological outcomes.

Surgical Outcomes of Secondary Alveolar Bone Grafting and Extensive Gingivoperiosteoplasty Performed at Mixed Dentition Stage in Unilateral Complete Cleft Lip and Palate.

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

The Impact of Facial Growth in Unilateral Cleft Lip and Palate Treated With 2 Different Protocols.

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

The effect of a small triangular skin flap on vermillion height after cleft lip repair: a photogrammetry study.

During primary cleft lip repair, a small triangular flap of about 2mm is sometimes required to achieve better symmetry of Cupid's bow. The aim of this study was to evaluate the symmetry of Cupid's bow, with and without the use of a small triangular skin flap (STSF). Forty-five children who underwent the repair of unilateral cleft lip between January 1999 and December 2000 were recruited. Twenty children had a STSF included in the repair (STSF group) an d 25 children underwent the same repair without the STSF (NSTSF group). Vermillion height was measured on the cleft and non-cleft sides using reference points. The t-test was used to compare the vermillion height ratio between the two groups. The mean age at surgery was 4±1.3months in the STSF group and 4.3±0.6years in the NSTSF group. There was no significant difference in vermillion height ratio at 5 years of age between the patients in the two groups. Thus, there is no difference in vermillion height ratio with or without a STSF in cleft lip repair. The use of a small triangular skin flap needs to be assessed carefully, as it will create an unsightly scar over the philtrum area.
