Medial incision approach in modified small double-opposing Z-plasty for Veau II cleft repair.

An encouraging outcome was described for the use of modified Furlow small double-opposing Z-plasty (sDOZ) using the medial incision (MIsDOZ) approach in repair of Veau type I cleft palate. This retrospective study assessed early results of using extended indication criterion of MIsDOZ for the management of consecutive non-syndromic patients with Veau II cleft palate treated by a single surgeon. Bardach two-flap plus sDOZ (two-flap approach) or medial incision approach with a tension-driven stepwise application of lateral palatal incisions (soft palate only, von Langenbeck type, or two-flap type) were applied. Surgical (age, cleft width, operative time, hospital stay, and complication)- and auditory-perceptual assessment-related data were collected. Two-flap approach (n = 21) demonstrated a significantly (p < 0.001) increased operative time (132.8 ± 12.2 versus 114.8 ± 19.9 min, respectively) and higher use of lateral incisions (100% versus 44.4%) than medial incision approach (n = 27), with no significant (p > 0.05) difference for age at surgery (13.0 ± 6.1 versus 13.6 ± 5.8 months), cleft width (8.5 ± 4.1 versus 8.7 ± 3.8 mm), hospital stay (1.0 ± 0 versus 1.0 ± 0 day), and complication (0% versus 0%) and hypernasality (9.5% versus 7.4%) rates. In conclusion, the medial incision approach for Veau II cleft repair resulted in reduced need for lateral palatal incision with no increase of complication or hypernasality rates.

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.

Scar Outcome in Unilateral Complete Cleft Lip Repair: A Comparative Analysis of Vertical Lip Lengthening Strategies Using the Rotation-Advancement Concept.

OBJECTIVE: To assess the differences in scar outcomes between modified rotation-advancement techniques proposed by Drs. Mohler and Noordhoff, designed to address issues such as inadequate vertical lip length and scarring on the upper third of the lip in the original rotation-advancement technique. DESIGN: Retrospective single-surgeon (RD) study. PATIENTS: Consecutive non-syndromic children (n = 68) with unilateral complete cleft lip and palate. INTERVENTIONS: Modified Mohler (columellar backcut reconstructed with C flap; n = 34) and modified Noordhoff (lower, medially-created backcut reconstructed with laterally-based triangular skin flap; n = 34) repairs. MEAN OUTCOME MEASURES: Using 12-month postoperative frontal photographs, scar evaluations (overall and superior, middle, and inferior portions of the lip) were appraised by an assessment panel composed by independent professional and nonprofessional raters employing four validated qualitative scar assessment scales: Manchester Scar Scale, modified Scar-Rating Scale, Stony Brook Scar Evaluation Scale, and Visual Analog Scale. Quantitative computerized photogrammetric scar widths of the superior, middle, and inferior portions of the upper lip were also measured. RESULTS: The modified Noordhoff method showed significantly (all P < .001) better scar quality for the overall scar and superior portion of the scar in all four scales compared to the modified Mohler method, with no significant (all P > .05) difference for the middle and lower portions. No significant difference (all P > .05) was observed for photogrammetric scar width measurements. CONCLUSION: The modified Noordhoff technique provided better qualitative results for unilateral complete cleft lip-related scars compared to the modified Mohler technique.

Comparison between one-jaw and two-jaw designs in virtual surgery planning for patients with class III malocclusion.

Orthognathic surgery is highly effective for treating maxillomandibular discrepancies in patients with class III malocclusion. However, whether one- or two-jaw surgery should be selected remains controversial. Our study aimed to evaluate quantitative differences between one-jaw and two-jaw surgical designs. In total, 100 consecutive patients with skeletal class III malocclusion who underwent orthognathic surgery with preoperative three-dimensional simulation between August 2016 and November 2021 were recruited. Based on the same final occlusal setup, a two-jaw surgery design and two types of one-jaw design were created. In total, 400 image sets, including preoperative images and three types of surgical simulation, were measured and compared. The one-jaw mandibular setback design led to improvement in most cephalometric measurements and facial symmetry. Although the one-jaw maxillary advancement design improved the ANB angle and facial convexity, it induced maxillary protrusion and reduced facial symmetry. Compared with the other designs, the two-jaw design provided significantly closer cephalometric measurements to the normative values, better symmetry, and less occlusal cant. Overall, the two-jaw design provided a quantitatively better facial appearance in terms of symmetry, proportion, and profile. Although an optimal surgical design necessitates thorough preoperative evaluation and a shared decision-making process, two-jaw surgery can be considered for improving overall facial esthetics and harmony.

Validating the Modified Small Double Opposing Z-Plasty for Palatal Lengthening in Primary Palatoplasty.

OBJECTIVE: To appraise the degree of intraoperative palatal lengthening with the modified Furlow small double-opposing Z-plasty (sDOZ). DESIGN: Retrospective single-surgeon (R.D.) study. PATIENTS: Nonsyndromic children (n = 167) with Veau types I to IV cleft palates who underwent primary sDOZ palatoplasty. INTERVENTIONS: Intraoperative measurements of palatal lengths and widths were collected using calipers, paper rulers, and metal rulers before the administration of local anesthetic solution and before the removal of the mouth gag (initial and final palatal dimensions, respectively). MAIN OUTCOME MEASURES: Assessment of the intraoperative percentage change (difference between final and initial values) in surface palatal length, straight palatal length, and soft palatal length. Bivariate and multivariate analyses were performed to identify independent predictors (sex, age at surgery, Veau, Kernahan/ Stark, and Randall classifications, widest cleft width, presence of lateral relaxing incision, type of coverage with buccal fat flap, and postoperative complications) of soft palatal lengthening. RESULTS: Surface palatal, straight palatal, and soft palatal lengths had an intraoperative increase of 8%, 14.7%, and 27.7%, respectively. The degree of intraoperative soft palatal lengthening significantly varied among Veau cleft types (I = II < III = IV). Veau type III and cleft lip/palate were independent positive predictors (P < .001) of soft palatal lengthening, while other tested variables were not correlated (P > .05) with this outcome. CONCLUSIONS: Overall intraoperative palatal lengthening occurs with the modified sDOZ palatoplasty, with differences within the spectrum of cleft palate deformity.

Secondary Bilateral Cleft Rhinoplasty: Achieving an Aesthetic Result.

BACKGROUND: Secondary rhinoplasty in patients with bilateral cleft lip poses ongoing challenges and requires a reliable method for achieving optimal outcomes. OBJECTIVES: The purpose of this study was to establish a safe and effective method for secondary bilateral cleft rhinoplasty. METHODS: A consecutive series of 92 skeletally matured patients with bilateral cleft lip and nasal deformity were included. All had undergone secondary open rhinoplasty, performed by a single surgeon with a bilateral reverse-U flap and septal extension graft, between 2013 and 2021. Medical records of these 92 patients were reviewed to assess the clinical course. A 3-dimensional (3D) anthropometric analysis and panel assessment of 32 patients were performed to evaluate the aesthetic improvement, with an age-, sex-, and ethnicity-matched normal control group for comparisons. RESULTS: The methods showed statistically significant improvement in addressing a short columella (columellar height), short nasal bridge (nasal bridge length), de-projected nasal tip (nasal tip projection, nasal dorsum angle), poorly defined nasal tip (nasal tip angle, dome height, and panel assessment), and transversely oriented nostrils (columellar height, alar width, nostril type). Importantly, these improvements were accompanied by a low complication rate of 4%. However, upper lip deficiency over the upper lip angle and labial-columellar angle remained without significant improvement. CONCLUSIONS: In this study we described effective secondary rhinoplasty, which was composed of a bilateral reverse-U flap and septal extension graft, with acceptable outcome. The 3D anthropometric analysis and panel assessment clarified that our rhinoplasty procedure could bring the nasal morphology in these patients closer to the normal data.

Septal extension graft in cleft rhinoplasty: Patients with secondary unilateral cleft lip nasal deformity.

BACKGROUND: Tip refinement procedure is still controversial in secondary unilateral cleft rhinoplasty. The aim of this study was to assess whether septal extension graft improved nasal and tip deformity and achieved a normal profile with clinical and 3D morphometric analyses. METHODS: A consecutive series of 194 skeletally mature patients with unilateral cleft were included and analyzed. All had undergone secondary open rhinoplasty, performed by a single surgeon, with the use of septal extension graft between 2013 and 2021. Clinical data were collected, and 3D morphometric measurements were performed. An age-, sex-, and ethnicity-matched normal group was included for comparisons. RESULTS: Our standard procedures included open approach combining reverse U incision, septal extension graft, dorsal augmentation, lip revision, and vermilion augmentation. The postoperative outcome showed significantly increased numerical values (nasal bridge length, nasal height, nasal tip projection, nasal dorsum angle, columellar angle, columellar-lobule angle, nostril height ratio, nasal surface area, nasal volume) and decreased numerical values (alar width, tip/middle deviation, nasal tip angle, labial-columellar angle) than the preoperative morphology. The postoperative measurement showed significantly higher numerical values (nasal protrusion, tip/middle deviation, nasal dorsum angle), and lower numerical values (columellar-lobule angle, nostril height ratio, alar width ratio) than the control group. CONCLUSION: This study revealed that our secondary cleft rhinoplasty significantly improved the under-projected, up-rotated, deviated, and poorly defined tip as well as short nasal bridge deformities. The technique could result in the nose of the patients with cleft lip nasal deformity being closer to that of the normative profile.

Modified Medial Incision Small Double-Opposing Z-Plasty for Treating Veau Type I Cleft Palate: Is the Early Result Reproducible?

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

Favorable Transverse Maxillary Development after Covering the Lateral Raw Surfaces with Buccal Fat Flaps in Modified Furlow Palatoplasty: A Three-Dimensional Imaging-Assisted Long-Term Comparative Outcome Study.

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

The Effect of Arch Cartilage Graft and Tajima Reverse U Approach in the Secondary Reconstruction of Unilateral Cleft Lip Nasal Deformity.

ABSTRACT: Secondary cleft lip nasal deformity is complicated with wide spectrum of defect and varied reconstructive procedures. There has been no unanimous solution for a given problem. In case of a localized alar depression in unilateral cleft lip nasal deformity, the conchal cartilage applied as arch graft was proposed. Patients were recruited from database of craniofacial center who received Tajima method and arch cartilage graft. Inclusion criteria were patients with unilateral cleft lip nasal deformity after skeletal maturity. Through a reverse U incision, the lower lateral cartilage was dissected and released from the skin and the contralateral cartilage. The harvested conchal cartilage graft was trimmed to 25 to 30 by 8mm in size, and inserted as arch shape overlying the cleft side lower lateral cartilage. Transdomal fixation sutures were made. Outcome assessment was performed, and the nostril and alar dimensions were measured. Thirty-nine patients were eligible for evaluation of the surgical outcome. Majority of patients underwent simultaneous lip revision (97%). No surgery-related complications were noted in this series. Satisfaction to the nasal reconstruction was reported in 85% of patients. Further minor nasal revisions were performed in 6 patients (15%). Quantitative measurement showed statistically significant improvement in nostril height, alar height and alar width after the surgery. It is concluded that the Tajima reverse U approach plus arch cartilage graft is an effective method for secondary reconstruction of the unilateral cleft lip nasal deformity in selected patients presenting with cleft side alar depression.5.

Facial Appearance and Psychosocial Features in Orthognathic Surgery: A FACE-Q- and 3D Facial Image-Based Comparative Study of Patient-, Clinician-, and Lay-Observer-Reported Outcomes.

Outcome measures reported by patients, clinicians, and lay-observers can help to tailor treatment plans to meet patients' needs. This study evaluated orthognathic surgery (OGS) outcomes using pre- and post-OGS patients' (n = 84) FACE-Q reports, and a three-dimensional facial photograph-based panel assessment of facial appearance and psychosocial parameters, with 96 blinded layperson and orthodontic and surgical professional raters, and verified whether there were correlations between these outcome measurement tools. Post-OGS FACE-Q and panel assessment measurements showed significant (p < 0.001) differences from pre-OGS measurements. Pre-OGS patients' FACE-Q scores were significantly (p < 0.01) lower than normal, age-, gender-, and ethnicity-matched individuals' (n = 54) FACE-Q scores, with no differences in post-OGS comparisons. The FACE-Q overall facial appearance scale had a low, statistically significant (p < 0.001) correlation to the facial-aesthetic-based panel assessment, but no correlation to the FACE-Q lower face and lips scales. No significant correlation was observed between the FACE-Q and panel assessment psychosocial-related scales. This study demonstrates that OGS treatment positively influences the facial appearance and psychosocial-related perceptions of patients, clinicians and lay observers, but that there is only a low, or no, correlation between the FACE-Q and panel assessment tools. Future investigations may consider the inclusion of both tools as OGS treatment endpoints for the improvement of patient-centered care, and guiding the health-system-related decision-making processes of multidisciplinary teams, policymakers, and other stakeholders.
