Force Balance Reconstruction of the Orbicularis Oris in Secondary Unilateral Cleft Lip Deformity.

Secondary unilateral cleft lip deformities are commonly observed in patients with cleft lip and traditional surgical methods can't completely tackle this problem. The purpose of this study was to evaluate the outcomes of a novel surgical technique using force balance reconstruction of the orbicularis oris. 53 patients with secondary unilateral cleft lip deformity were included in this study, in which the orbicularis oris muscle was reconstructed symmetrically to achieve optimal force balance. Photometric 2d indexes were employed to evaluate the outcome of 27 patients, and 3d indexes for the remaining 26 patients. Aesthetic evaluation and parent-patient satisfaction surveys were also recorded. Significant differences were found in the following: (1) LH (the lip height), LW (the lip width), D1(the vertical distance from the white roll to the vermilion bottom at the christa philtra points) and D2(the vertical distance from the christa philtra points to the facial midline) when comparing preoperative and postoperative 2D images; (2) LH, LW, D1 and D2 when comparing preoperative and follow-up 2D images; (3) RMS (root mean of square) when comparing preoperative and postoperative 3D images. Aesthetic evaluation in the follow-up period was a mean of 4.29, while parent-patient satisfaction of the overall appearance was a mean of 4.41. The results suggest this new muscle reconstruction technique can significantly improve the surgical outcome of secondary unilateral cleft lip deformities.

Rhinoplasty for unilateral cleft lip deformity

Cleft nasal deformity is most common sequel after cleft lip and palate surgery. The severity of the nasal deformity is usually decided by initial cleft state, previous operation skill and postoperative care. Secondary cleft rhinoplasty for unilateral cleft patient requires both esthetic and functional results. Understanding the anatomic defect and growth potential after cleft operation help to perform favorable secondary rhinoplasty. Surgical methods for deformed cleft nose are diverse and each methods have pros and cons. Closed or open rhinoplasty with or without cartilage graft and piriform augmentation are the mainstay for cleft rhinoplasty. The purpose of this study was to describe current concepts in secondary rhinoplasty for unilateral cleft lip nasal deformity. Secondary rhinoplasty for cleft patients requires an understanding of the anatomic situation, and the use of cosmetic and functional rhinoplasty techniques for its successful management.

Repair of Scars and Tissue Deficiency With Free Grafts of Full-thickness Scalp in Secondary Unilateral Cleft Lip Deformity.

Although surgical techniques have developed, the incidence of secondary cleft lip deformities after the primary repair is still high. Asymmetry of Cupid's bow and philtrum is a common presentation and a technical challenge to reconstruct the upper lip. The authors introduce a technique to use the free grafts of the full-thickness scalp for the correction of scars and tissue deficiency in secondary unilateral cleft lip deformity. Thirty-seven patients with a prominent scar, tight upper lip, deformed Cupid's bow and philtrum, and irregular vermillion border were included in this study. The specific points of interest were assessed before and after surgery by independent examiners with both subjective and objective methods. All surgeries were successfully completed, and the assessment results were satisfactory. The rating scores of philtrum improvement was 1.6±0.4, the POSAS result of patient scales was 13.48±3.21, and the observer scale result was 11.98±3.88. The asymmetry of Cupid's bow was corrected ( P =0.004), the central tubercle of vermilion was more natural ( P =0.001), and the irregular vermillion border was improved ( P =0.015). The results presented significant differences before and after surgery. This method could be an optional treatment for repairing scars and tissue deficiency in secondary unilateral cleft lip deformity.

Longitudinal Anatomic Analysis of Primary Cleft Lip Rhinoplasty Outcomes.

Background: The unilateral cleft lip deformity is associated with nasal deformities with secondary functional and aesthetic challenges. Objectives: Compare the change in nasal symmetry before and incrementally after primary endonasal cleft rhinoplasty concurrent with lip repair. Methods: This is a retrospective chart review of infants undergoing unilateral cleft lip repair. Data collection included demographics, surgical history, and pre- and postoperative alar and nostril photographs analyzed with Image J. Statistical analysis was done using linear and multivariable mixed effect models. Results: Twenty-two patients with a near even gender distribution (46% female) and primarily left-sided cleft lips underwent unilateral lip repair at a mean age of 3.9 months (median 3.0, range 2-12). Mean pre- and postoperative alar symmetry ratios were 0.099 (standard error [SE] 0.0019) and -0.0012 (SE 0.0179), with zero representing perfect symmetry and negative values indicating overcorrection. These values at 1, 2-4, 5-7, 8-12, 13-24, and 25+ months were 0.026, 0.050, 0.046, 0.052, 0.049, and 0.052 (SE range: 0.0015-0.0096), respectively, demonstrating stability of the alar symmetry 4 months postrepair. Conclusions: In this study, patients who underwent an overcorrective primary cleft rhinoplasty concurrent with lip repair had an initial regression of symmetry within the first 4 months postoperatively, followed by observed stabilization.

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

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. 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. 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. 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.

Outcomes of Open Rhinoplasty for Unilateral Cleft Patients using Photogrammetric Analysis - An Evaluative Study.

Secondary cleft rhinoplasty is a challenge due to the complex anatomy of the nose, with structural deformity and difficulty in surgical management. This study aimed to evaluate the effect of an anatomical-based approach on enhancing tip and alar symmetry in secondary unilateral cleft rhinoplasty using photogrammetric evaluation. The study was conducted on 57 adult patients seeking rhinoplasty after primary repair of congenital unilateral cleft lip deformity. All patients were operated upon using an external open rhinoplasty approach using an anatomical-based surgical technique. The cases were periodically followed up at three, six, 12 and 18 months for both aesthetic and functional outcomes with photogrammetric analysis of facial profile using the software Mirror Suite programme to compare before and after the surgical procedure. The photogrammetric analysis showed a significant improvement of facial angles (P = 0.05). The nasofrontal angle changed from a median of 146° to 132.5°, nasolabial angle of 73° to 95°, nasofacial angle of 21.5° to 32° and nasomental angle of 105° to 130°. The rotation angle of the nasal tip showed a significant cephalic rotation with a mean increase of the tip elongation of 1.8 cm achieved per lateralised millimetre. Secondary rhinoplasty in unilateral cleft deformities needs accurate evaluation of the anatomical and pathological abnormalities. Open approach is preferred with using costal cartilage graft allowing adequate columellar lengthening, maxillary enhancement and alar repositioning which leads to optimise the definition, projection and cephalic rotation with better stabilisation and symmetry of the nasal tip.

Unilateral cleft lip repair

Cleft lip and palate are considered one of the most common birth defects that possess significant medical, psychological, social, and financial implications on the affected individuals and families.The unilateral cleft lip deformity can be repaired by many techniques, despite the numerous eponymous techniques, all are derivedfrom three basic “methods” for unilateral cleft lip repair: the straight-line technique, the triangular flap technique, and the rotation-advancement technique. The Evaluation of the long-term outcomes of the primary cleft lip repair is extremely important in order to study surgical outcome and also predict the evolution of the scar over time.There is considerable variation among studies in measuring and reporting outcomes after cleft lip repair. Some investigators have used clinical photographs with subjective scoring, whereas othersuse 3-dimensional imaging, computerised measurements or anthropometry.

Symmetrical Reconstruction of the Orbicularis Oris in Correction of Secondary Unilateral Cleft Lip Deformity.

Symmetrical Reconstruction of the Orbicularis Oris in Correction of Secondary Unilateral Cleft Lip Deformity.

Force balance reconstruction of orbicularis oris in correction of unilateral cleft lip deformity.

Short-term outcome evaluation for the correction of unilateral cleft lip deformity with a new technique. Forty-four patients with unilateral cleft lip deformity were included in the study and in which the orbicularis oris muscle was reconstructed to achieve the optimal force balance of reconstructed orbicularis oris. The photometric two-dimensional indexes, including the philtrum oblique angle and asymmetry ratios (lip height, lip width, vertical distance from the white roll to the vermilion bottom at the Cupid's bow point, and vertical distance from the Cupid 's bow points to facial midline), were employed to measure and evaluate the outcome. Several indexes showed statistically significant difference, and they included the philtrum oblique angle, asymmetry ratio of the lip height, and asymmetry ratio of the vertical distance from the white roll to the vermilion bottom at Cupid ' s bow points (P<0.05). The results suggested that the new muscle reconstruction technique can significantly improve the short-term outcome of the correction of unilateral cleft lip deformity.

The Melbourne Classification of the Complete Unilateral Cleft Lip Based on Hypoplasia

Background:The hypoplastic lateral lip element within the cleft lip presentation is a recognized entity that has been recently shown to be more common on the right side. The spectrum of such change is yet to be defined. The authors propose the Melbourne classification system of cleft lip hypoplasia and see it as an important step towards discerning the relevance of these anatomical observations to the management of cleft lip/palate patients.Methods:This is a retrospective observational study of patients with complete unilateral cleft lips treated by the senior author (DKC) at the Royal Children's Hospital, Melbourne. Patient charts were retrospectively reviewed and patients were classified into different degrees of hypoplasia based on preoperative, intraoperative, and postoperative photography. Data was reported using descriptive statistics.Results:Fifty-nine patients with complete unilateral cleft lip deformity were grouped according to lateral lip element hypoplasticity. Twenty patients had right-sided clefts and 39 patients had cleft lips on the left side. Of those with right-sided clefts, 18 patients had evidence of hypoplasia (90%). Three patients had Type 1 deformities, 3 patients were Type 2, and 12 patients were Type 3. Patients with left-sided clefts were found to have hypoplasia less frequently with 15 patients showing evidence (38.5%).Conclusions:The authors report a classification system of hypoplasia involving the lateral lip element in complete unilateral cleft lip. The authors propose this classification system as a new measure of cleft severity that will have implications for patient expectations, surgical planning, and future outcome studies.

Using rotation cross-advancement flap for repairing complete unilateral cleft lip and nasolabial deformity

To evaluate the efficacy of rotation cross-advancement flap method in repairing the nasolabial deformity of complete unilateral cleft lip. A retrospective study was performed to analyze the children who were treated by using the rotating cross-advancement flap for repairing the complete unilateral cleft lip at the Fujian Medical University Union Hospital from October 2018 to July 2019. The clinical data such as patient's lip height, lip length, nostril height, nostril width, nostril area and so on were collected at the pre-operation, post-operation and following-up visits respectively and used to evaluate the efficacy of the treatment. Six children were included in the present study. The ratios of lip height on noncleft side to cleft side were 2∶1 at the pre-operation time. The ratios of nostril height on the noncleft side to the cleft side were about 2∶1. The ratios of the width and the area of the nostril were 1∶2 to 1∶3. At the post-operation time, the ratios of length and height of the lip at the cleft side to the noncleft side were around 1∶1. The shape of the nostrils and nasolabial fold were almost symmetrical between the cleft side and noncleft side. The shapes of the nasal sill were acceptable and the postoperative scars were not obvious. There were no obvious incision healing complications and the treatment effects were satisfactory. Rotation cross-advancement flap method was safe and reliable for repairing the nasolabial deformities in children with complete unilateral cleft lip.

Triangular flap technique for unilateral cleft lip deformity

The triangular flap lip repair is one of the two main techniques used for the correction of a cleft lip deformity worldwide. Many surgeons in Indian subcontinent and Europe use the triangle flap technique as their first choice. This CME article describes the details of the triangular flap technique as modified by Dr. C P Sawhney. The rationale of the technique, lip markings, planning of incisions, and the detailed operative steps are described. The merits and demerits of this versatile technique are also discussed.

Millard's rotation advancement technique for unilateral cleft lip repair

The unilateral cleft lip deformity includes defects of the lip and also the associated deformities in the nose. The Millard's rotation advancement technique is a versatile one for the repair of these deformities. The principle of the technique is that the raised Cupid's bow point medial to the cleft is brought down level with its noncleft side counterpart by a rotation incision, which extends to the base of the columella and ends with a back cut. The resulting defect beneath the base of the columella is filled with an advancement flap from the cleft side. The advantages of the techniques are many. The most significant one is that it adheres to the basic principles of esthetic surgery, with the main scars being along the relaxed skin tension lines. It is a versatile technique producing optimal results in all types in unilateral cleft lip patients ranging from the microform to the widest of complete clefts. The incision in this technique is so placed that there is easy access to address the associated defects of the nose. Technical refinements have been added to the classical description of the procedure to address the deficiencies in the repair. We describe important refinements introduced at our center by Dr. H. S. Adenwalla. Universally, this technique is still the most popular.

Three-Dimensional Computed Tomography Reconstruction and Measurement of Nasal End Deformity in Complete Unilateral Cleft Lip and Palate.

The repair of nasal deformities secondary to cleft lip and palate is complex and requires reliable preoperative nasal 3-dimensional assessment. This study explored nasal end (defined as the lower third of the external nasal and vestibular parts of the nasal cavity) deformities secondary to unilateral complete cleft lip and palate. Three-dimensional nasal end morphometric measurements were obtained from 48 patients who had undergone Millard cleft lip repair and reached skeletal maturity (cleft group) and from 36 age- and ethnicity-matched normal subjects (control group). For the cleft group, paired t tests and 1-way analysis of covariance were used to evaluate the internal and external morphological characteristics of the cleft and noncleft sides of the nasal end, and correlation analysis was done to evaluate the relationship between cleft-side measurements. In the cleft group, the cleft side showed significantly smaller nasal vestibular volume and skin area, nostril area, nasal column length, and nostril height and greater nostril base length and nasal alar length than the noncleft side (all P < 0.05). Controlling for sex, there were significant differences in the nasal vestibular volume and skin area, internal nasal valve area, long nostril diameter, nostril base length, columella length, nostril height, and nasal alar length between the cleft and control groups (all P < 0.05). On the cleft side, the area of the skin lining of the nasal vestibule positively correlated with the alar length (r = 0.67, P < 0.05). Three-dimensional nasal end reconstruction provides a more detailed preoperative nasal end morphological evaluation than previously available techniques. Level III, case-control study.

Variational Characteristics of Nasolabial Appearance and Its Influencing Factors for the Unilateral Cleft Lip Repair With Modified Huaxi Technique.

After many years in clinical practice, the authors found that the long-term aesthetics of the upper lip and nose following repair of a unilateral cleft lip deformity using the Huaxi method remained unsatisfactory. The immediate postoperative effect was often good, while the long-term postoperative effect was poor. Therefore, this study aimed to evaluate the characteristics and influencing factors of a modified Huaxi method for repairing unilateral cleft lip over time, and to explore the relationship between immediate and long-term outcomes after cleft lip surgery. Patients with unilateral cleft lip who visited the Department of Maxillofacial Surgery of the Stomatological Hospital of Zunyi Medical University from June 2014 to March 2016 were selected. The study group consisted of 51 consecutive patients (30 boys and 21 girls), aged between 3 months and 2 years. Of these, 24 presented with complete unilateral cleft lip (12 wore a nasoalveolar mold as required, 12 did not) and 27 with incomplete unilateral cleft lip (13 wore a nasoalveolar mold as required, 14 did not). Photographs were taken of 51 patients before surgery and immediately, 7 days, and 6 months postoperatively. Various indexes of nasolabial contour of each patient were measured using iWitness photogrammetry, and the slit width; lip height ratio, lip width ratio, nostril width ratio, and nostril height ratio of the healthy side; and degree of deviation of the nasal columella were calculated. Long-term symmetry of lip height and width remained stable postoperatively (P > 0.05), whereas nostril height symmetry was significantly reduced (P > 0.05). Nasal width symmetry and midpoint deviation of the nasal columella were stable in patients with nasoalveolar molding (P > 0.05), but significantly decreased in patients without nasoalveolar molding (P < 0.05). In patients with complete unilateral cleft lip, there was a significant correlation between fissure width and lip width symmetry 6 months postoperatively (r = 0.431, P < 0.05). The symmetry of the upper lip is satisfactory and stable following surgical repair with the modified Huaxi technique. However, undercorrection of nasal symmetry is commonplace. Fissure width and nasoalveolar molding may influence long-term aesthetics following unilateral cleft lip repair.

The unilateral cleft lip repair

ObjectiveTo determine if there is a benefit of 2-stage cleft lip repair in regard to improving facial symmetry and facilitating definitive lip, nose, and palate repair. Study designRetrospective chart review of patients born with complete, unilateral cleft lip deformity that underwent a two-stage repair described as a stage 1 straight line repair and a stage 2 modified Millard repair, for which a complete set of records, and peri-operative and post-operative photos were available. All cases were performed by a single surgeon. SettingTertiary care center craniofacial team. MethodsMeasurements were taken from intraoperative, perioperative, and postoperative images of patients before and after each stage. Ratios were then created comparing the affected size to the unaffected side, and these were averaged between observers. ResultsA 19% increase in the width of area of the presumptive C flap was obtained between the unrepaired and the post-stage I images. The nostril width of the cleft side was 1.2× the width of the unaffected side, demonstrating a 140% decrease in nostril width at the completion of stage II. The cleft side nostril width was maintained slightly larger than the noncleft side as desired. Symmetry of the upper lip length was achieved, as the length of the cleft side lateral lip after stage II was 92% of the unaffected side. ConclusionWe believe this study provides evidence for our observations that a two-stage repair can be performed with functionally and aesthetically pleasing outcomes as an alternative to presurgical nasoalveolar molding.

Comparative study between fisher anatomical subunit approximation technique and millard rotation- advancement technique in unilateral cleft lip repair

ABSTRACT Introduction: The ideal lip repair is characterized by; the symmetrical shape of nasolabial folds and both alae of the nose with a natural-looking philtrum and Cupid’s bow in both static and dynamic states, in addition to a hidden scar. Objective: to compare between Fisher anatomical subunit approximation technique and Millard rotational advancement technique in unilateral cleft lip repair. Methods: Prospective study for 40 patients presented to Alexandria Main University hospital with unilateral cleft lip deformity between March 2019 and October 2020. Twenty patients with unilateral cleft lip deformity were repaired by Fisher anatomical subunit approximation technique, while the other twenty were repaired by Millard rotational-advancement technique. The postoperative photographs of the patients were captured and processed in computer photogrammetry software through which anthropometric parameters including (lip height, lip width, vermilion height, and alar base width) were compared between the normal side and the repaired side. In this software, each anthropometric parameter length on the normal side is taken as a control with a fixed value of (1) then the same parameter on the repaired side was measured as a ratio of this value to avoid bias. Comparison between both groups for assessment of the quality of cleft lip repair was also done based on Steffensen grading criteria. Results: Comparison between both techniques in unilateral cleft lip repair showed that there was no significant difference between them in the anthropometric measurements. While the comparison between the two groups using Steffensen grading criteria showed that Fisher’s technique surpassed Millard’s technique. Conclusion: We recommend the use of the Fisher anatomical subunit approximation technique in unilateral cleft lip repair for its superior results over the Millard rotational advancement technique.

The nasal cantilever technique in children undergoing primary cleft lip surgery: novel concepts and review

BackgroundNasal deformity associated with cleft lip deformity is a challenging issue, encompassing controversies, theories, and a diversity of techniques. Historically, esthetic outcomes have ranged from being below expectations to barely acceptable.MethodBased on the concept that the nasal cartilaginous framework in clefts is similar to that of a collapsing pyramid, a novel suspension technique has been described. The entire cartilaginous structure is lifted from the infratip segment with a loop suture and is secured in a cantilever fashion onto the periosteum overlying the nasal bone. This part of the operation is performed in a semiclosed manner. The technique is applied during primary surgery in bilateral and unilateral nasal cleft lip deformities, with changes in the orientation of the cantilever loop suture. Studies conducted by Masters S. Tajima, H. McComb, H. Thomson, D. Fisher, and J. Mulliken, which are most relevant to this article, have been reviewed and discussed throughout.ResultsThe technique was first applied over 10 years ago. A case series of nine children whose parents consented to the developing technique is presented with follow-up ranging from months to years, along with technical descriptions and illustrative drawings. None of these cases had preoperative orthopedic correction, molding, or postoperative nostril splints. The esthetic outcome was optimal enough; none of the cases requested a secondary correction.ConclusionThe nasal cantilever technique is a novel concept in cleft nasal deformity, which can be used in conjunction with an appropriate lip technique, per the surgeon’s discretion. Other than a learning curve, we believe that it provides a solid correction by securing the cartilaginous structures after they have been mobilized to a stable base, the nasion.
