Int J Oral Maxillofac Surg 2024:S0901-5027(24)00245-5. [PMID: 39095303 DOI: 10.1016/j.ijom.2024.07.017] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/19/2023] [Revised: 07/18/2024] [Accepted: 07/22/2024] [Indexed: 08/04/2024]
Abstract
When performing a unilateral incomplete cleft lip repair, it is essential to create a good sub-structure of the upper lip contour, reconstruct the orbicularis oris muscle, and prevent an unwanted scar. The aim of this study was to investigate the clinical effect of muscle reconstruction using a five-flap method with a short straight-line incision in unilateral incomplete cleft lip repair. Thirty-two infants with unilateral incomplete cleft lip were treated with this method between April 2020 and February 2023. A short straight-line incision was designed along the philtral column. The orbicularis oris muscle was reconstructed with a five-flap method in three areas: nasal base area, white lip area, and red lip area. Patient outcomes were assessed through subjective evaluation and anthropometric measurements. No patient experienced any postoperative complications. The philtral column and Cupid's bow were well reconstructed. Deviation of nasal columella was corrected and the nasal floor was elevated. Functionally and aesthetically satisfactory outcomes were obtained in all patients over long-term follow-up. In conclusion, this technique was able to create a good sub-structure of the nasolabial contour and bring a significant improvement in bilateral symmetry, showing it to be an effective method for incomplete unilateral cleft lip repair with minimal scarring.

Abstract
BACKGROUND The long-term postoperative outcomes of two different orbicularis oris muscle reconstruction techniques in patients with unilateral incomplete cleft lip were compared. METHODS Forty-seven patients with unilateral incomplete cleft lip were assessed in this study, where 23 underwent a traditional method of reconstruction and 24 underwent a novel method. Preoperative measurements, postoperative results, and 3-year follow-up outcomes were measured by photographic anthropometric analysis. Five upper lip measurement indices and 8 nostril indices were included. RESULTS The postoperative outcomes showed that the shape of the lip and nose was more symmetric with the new surgical method compared with the conventional technique. Long-term outcomes after 3 years, although characterized by minimal changes during maxillofacial development, showed better maintenance of lip and nostril symmetry in the novel-method group. CONCLUSION The novel technique seeks to balance the perinasal and perioral muscles, resulting in improved symmetry compared with the traditional reconstruction technique.

Abstract
BACKGROUND Microform cleft lip is the mildest type of cleft lip without obvious defects of the upper lip. The nose deformities of microform cleft lip include flattened nostril rim, alar base asymmetry, and septal deviation. A hidden skin incision with nasal base muscle reconstruction was introduced in nose deformities of microform cleft lip. METHOD To investigate the operative effect, we reviewed 21 patients with microform cleft lip treated with a hidden skin incision with nasal base muscle reconstruction from May 2020 to October 2022. Photogrammetric nasal morphometric measurements were compared preoperatively and six months postoperatively. The proportional value was obtained from the cleft and the noncleft sides, and paired t-test analysis was used to evaluate the surgical outcome. RESULT Significant differences were found in all nasal morphologic measurements at 6 months postoperatively compared to preoperatively (p < 0.05). After surgery, the alar base and nostril were narrowed, while the lateral lip height was increased on the affected side. The height of the nostrils on the affected side was increased, and the nasal columella deviation was released. In addition, the ratio of the cleft-to-noncleft nostril area was closer to 1.0 after surgery. CONCLUSION The unilateral microform cleft lip nasal deformity can be repaired through a small hidden incision.

J Plast Reconstr Aesthet Surg 2024; 89:134-141. [PMID: 38181634 DOI: 10.1016/j.bjps.2023.10.131] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/08/2020] [Revised: 07/19/2023] [Accepted: 10/30/2023] [Indexed: 01/07/2024]
Abstract
BACKGROUND Bilateral cleft lip is a congenital defect often accompanied by secondary lip and nose deformity. The current classification system for secondary cleft lip deformity has limitations in guiding surgical planning. In this article, we report a method for secondary bilateral cleft lip classification that can guide surgery on the basis of the pathological anatomy of the columellar and upper lip. METHODS Photographs of patients were retrospectively classified into four types on the basis of the ratio of columellar height to alar base width (CH/AW) and upper lip protrusion (UP) to lower lip, as follows: type I - with CH/AW ≥ 0.2 and UP ≥ 0; type II - with CH/AW ≥ 0.2 and UP <0; type III - with CH/AW < 0.2 and UP ≥0; type IV - with CH/AW < 0.2 and UP < 0. Surgical treatments and the change of the nasal profile were documented. RESULTS A total of 105 patients from January 2008 to December 2018 were included in this study. The nasal profile was significantly improved in type III and IV patients with postoperative CH/AW values close to normal. The upper lip was distinctively retruded in type II and IV patients before treatment, and the postoperative view revealed improved upper lip protrusion with UP values close to normal. Ninety-eight patients reported satisfactory outcomes after treatment. CONCLUSIONS The new classification method described provides key information regarding the deformity of different types of secondary bilateral cleft lip patients and provides clear guidance for surgical planning on the basis of the anatomical defect of each type.

Abstract
BACKGROUND Neurovascular protection within the upper lip muscles is essential in muscle tension reconstruction and functional recovery during surgery. This study aimed to investigate a novel neurovascular protection method based on the intramuscular neurovascular partitions of the upper lip applied to nasolabial muscle biomechanical bionic surgery for secondary unilateral cleft lip repair and to evaluate postoperative outcomes. METHODS From November 30, 2019 to October 31, 2020, 50 consecutive patients with secondary unilateral cleft lips who underwent the modified biomechanical bionic surgery were reviewed retrospectively. Three-dimensional (3D) photographs of patients were collected preoperatively, 7-day postoperatively, and during long-term follow-up (at least 6 months). The Global Aesthetic Improvement Scale was used to evaluate surgical subjective outcomes, and statistical analysis of nasolabial measurements on 3D photographs was used to evaluate objective outcomes before and after surgery. RESULTS The Global Aesthetic Improvement Scale showed that 94% of patients had improved upper lip morphology and 92% had improved nasal morphology 7-day postoperatively. In all, 84% maintained favorable nasolabial morphology during long-term follow-up. Statistical results showed that the postoperative alar width, philtral depth, columellar angle, and nasal base inclination angle were significantly improved compared with preoperatively (P<0.01). The differences between the above 4 indexes were not statistically significant (P >0.05) between 7-day postoperatively and long-term follow-up, indicating that the postoperative lasting outcomes were satisfactory. CONCLUSIONS The novel method of neurovascular protection in nasolabial muscle biomechanical bionic surgery can achieve a long-term improvement of labial-nasal morphology and function in patients with secondary unilateral cleft lip.

Abstract
Background: Orbicularis oris muscle repair is key to successful unilateral cleft lip repair. Objective: To measure the lip symmetry after repair of the lip muscles in the midline compared with traditional repair on the cleft side. Methods: A retrospective review and photographic analysis of patients with complete cleft lip treated with the modified approach were carried out. Anthropometric analysis was done at pre-, immediate, and 1-year postoperatively, and at 1-year follow-up. Four upper lip and six nostril landmarks were measured. Results: Fourteen patients met inclusion criteria. Immediate postoperatively, the horizontal lip length on the cleft side was shorter than that on the noncleft side, but the discrepancy decreased as facial development progressed over the course of a year. Lip measurements at the 1-year follow-up were approximately symmetrical in vertical lip height, philtral height, and lateral lip height. Small changes in the nasal correction occurred at 1 year. Conclusion: A modified technique in the unilateral complete cleft lip repair seeks to balance the perinasal and perioral muscles and improve symmetric outcomes.

Abstract
Background: Most of the characteristic facial features of patients with unilateral macrostomia are attributed to the malformation of commissure muscles. This study aimed to evaluate a modified surgical treatment for such patients that focuses on both appearance and symmetry. Methods: Twenty-seven patients with macrostomia underwent surgery using the proposed method. Facial measurements were analyzed preoperatively, 1 week postoperatively, and during a long-term follow-up using statistical software. Results: The overall length ratio of the healthy and affected sides of the vermillion preoperatively, 1 week postoperatively, and during the long-term follow-up was 1:1.61, 1:1.01, and 1:1.00, respectively (all, p > 0.05). The overall angle between the pupil line and the commissure line was 9.90° preoperatively, 2.34° postoperatively, and 3.31° during the long-term follow-up. There was no statistically significant difference in the covering relation of the upper and lower lips between the affected and healthy sides postoperatively (p > 0.05). 3dMD Dynamic Surface Imaging System (3dMD, Atlanta, GA, USA) showed a symmetrical three-dimensional commissure structure during long-term follow-up measurements. Conclusions: The symmetry and appearance of patients with macrostomia commissure significantly improved following this modified surgical method.

Abstract
ABSTRACT The muscle flap reconstruction technique was developed based on the concept of muscle tension line groups, which elucidates how nasolabial muscle tension helps maintain the shape of the philtrum. To investigate the operative effect, we reviewed 43 patients with microform cleft lip and 102 patients with secondary cleft lip treated with muscle flap reconstruction between January 2018 and June 2020. The patients were scanned using the digital three-dimensional stereophotogrammetry face system pre- and post-operatively, and comparative analysis of three-dimensional (3D) images was used to highlight variations of the philtrum. Visual analog scales were used to assess surgical outcomes. More than 6 months after the surgery, comparative 3D images of 37 patients (86.04%) with microform cleft lip and 86 patients (84.31%) with secondary cleft lip showed visible improvement in the prominence of the affected column. In addition, visual analog scale scores showed that 38 microform cleft lip patients (88.37%) and 89 secondary cleft lip patients (87.25%) had a good appearance. The postoperative prominence of the philtral column in both groups improved significantly compared to before surgery (P < 0.001 and P < 0.001, respectively). There was no significant difference in scores for philtrum prominence pre- and post-operatively between the 2 groups (P > 0.05). Muscle flap reconstruction is an effective means to create the 3D configuration of the philtrum. The biomechanical properties of muscles play a vital role in the morphological maintenance of the philtrum.

Three-dimensional creation of the peak of Cupid's bow by muscle tension line group reconstruction in secondary cleft lip repair. Int J Oral Maxillofac Surg 2021; 50:1055-1058.

Abstract
The peak of Cupid's bow is a unique three-dimensional structure. Traditional reconstructive techniques focus only on the correction of vermillion border malalignment and the vertical discrepancy between Cupid's bow peaks from a two-dimensional perspective. The aim of this study was to introduce a novel technique - the muscle tension line group reconstruction technique - to recreate the Cupid's bow peak three-dimensionally in secondary cleft lip repair. With this technique the orbicularis oris muscle is divided into two flaps: a lateral one composed of pars marginalis and a medial one composed of pars peripheralis. The full thickness of the medial flap is sutured to the deep layer of the lateral flap, and the end of the lateral flap is then sutured to the dermis lateral to the philtral dimple to accentuate a depression. In this way, the two muscle flaps exert opposing skin traction on each side of the peak, which improves the vertical height as well as the lateral projection of the Cupid's bow peak. The postoperative outcomes indicate that this is a reliable technique for three-dimensional restoration of the Cupid's bow peak, with a stable and natural reconstructive appearance.

Abstract
BACKGROUND Crouzon syndrome is associated with severe respiratory impairment of the upper airway due in part to midfacial dysmorphology. We calculated the distinctive nasal diameter and pharyngeal airway volume in patients with Crouzon syndrome and compared them with age-matched control subjects. METHODS Children with computed tomography scans in the absence of surgical intervention were included. Computed tomography scans were digitized and manipulated using Surgicase CMF (Materialise). Craniometric data relating to the midface and airway were collected. For all linear measurements, mean percent increases or decreases were calculated relative to the size of control subjects, and volumetric assessment of the airway was tabulated. Statistical analysis was performed using t test. RESULTS Twenty-six computed tomography scans were included (control n = 17, Crouzon n = 9). All children were in early mixed dentition. Pharyngeal airway volume was decreased in patients with Crouzon syndrome relative to control subjects by 46% (P = 0.003). The distance from the posterior tongue to the posterior pharyngeal wall decreased 31% when comparing the Crouzon group versus the control (P = 0.04). CONCLUSIONS Three-dimensional analysis revealed notably decreased pharyngeal and nasal airway volumes in patients with Crouzon syndrome, but nasal bone tissue and soft tissue measurements showed very little change between patients and control subjects.

Abstract
INTRODUCTION The anatomy of the arterial branches in the upper lip and their relationships to soft tissue are not well described in the literature. The purpose of this study was to explore a method for visualizing the microvessels and soft tissue three-dimensionally to gain better understanding of the upper lip blood supply. MATERIALS AND METHODS Seventeen stillborn fetuses were injected with lead oxide-gelatin and stained with iodine. Thirty-four half upper lip specimens were obtained and scanned by micro-computed tomography. The images were then examined and Inveon analysis software was used for three-dimensional reconstructions. RESULTS The main supplies to the upper lip were from the superior labial and inferior alar arteries. In some cases, the infraorbital and lateral nasal arteries also branched off to the upper lip. The anatomical variations were classified into six types on the basis of the observed vascular composition patterns. The skin was supplied by the subcutaneous vascular network, formed by the superficial ascending branches of the superior labial and inferior alar arteries. The mucosa was supplied by the submucosal vascular network, formed by the deep ascending branches of the superior labial artery and the labial branches of the infraorbital artery. The muscles were supplied by small vertical branches from the subcutaneous and submucosal vascular networks. CONCLUSION This study provides new anatomical insight into the upper lip by describing the microvessels and the relationship between the arteries and the soft tissue involved. This is important information for clinical applications in upper lip plastic surgery.

Abstract
BACKGROUND The main phenotypic features of lesser-form cleft lip include nasal, philtrum, and vermilion deformities. The manifestations of lesser-form cleft lip vary greatly, and it is difficult to rebuild these subunits during the operation. METHODS "Three subunits" classification of lesser-form cleft lip was identified as nasal deformity (N), philtrum deformity (P), or vermilion deformity (V); and slight deformity (0) or obvious deformity (1). A total of 200 patients with lesser-form cleft lip were classified into one of the following 8 types: N1P1V1, N1P1V0, N0P1V1, N1P0V1, N0P0V1, N1P0V0, N0P1V0, or N0P0V0. Then the authors discussed the deformities of the lesser-form cleft lip and the reconstruction of the muscles in these subunits based on the microanatomic structure of the nasolabial muscle. RESULTS This retrospective review included 200 patients with a lesser-form cleft lip, who were seen at our center from 2015 to 2017. There were 149 (74.5%) N1P1V1, 11 (5.5%) N1P1V0, 13 (6.5%) N0P1V1, 4 (2.0%) N1P0V1, 8 (4.0%) N0P0V1, 10 (5.0%) N1P0V0, 1 (0.5%) N0P1V0, and 4 (2%) N0P0V0 clefts. The various deformities of nasal floor, philtrum ridge, and vermilion may suggest that the muscle bundles in these subunits are abnormal and the operation should be performed to simulate the running directions and tension lines of these local muscles. CONCLUSIONS The microanatomic structure and the tension lines of the nasolabial muscles can provide new perspectives for better understanding and repairing the lesser-form cleft lip in subunits.

Abstract
In the repair of unilateral cleft lip, the Cupid's bow, and vermilion on the affected side are sometimes lowered excessively. Methods involving skin and mucosa flaps have been used to correct this issue, but they pose some risk of scarring. The authors here describe a layered muscle flap technique that was based on the anatomical research of nasal-labial muscles, especially the levator labii superioris alaeque nasi muscle. This technique can be used to suspend the Cupid's bow and vermilion in secondary unilateral cleft lip repair. Forty-five patients with secondary unilateral cleft lip with excessively lowered Cupid's bows and vermilion on the affected side were included in this study, which lasted 3 years. These patients were treated using the layered muscle flap surgical technique. The heights of specific bilateral landmarks were measured on patient photos and used to define the symmetry of bilateral Cupid's bow and vermilion. The comparison between post-operative and pre-operative symmetries was used to evaluate the post-operative results, and most of them were satisfactory. The results were also mostly well retained in follow-up investigations. This layered muscle flap technique could be effective in selected cases.

Abstract
Importance The blood supply pattern of the partial-thickness musculomucosal pedicle flaps is different from the traditional Abbe flap. The arterial blood supply and venous drainage are highly reliable during clinical practice. Objective To describe the reconstruction of the philtrum in the cross-lip flap transfer using nasolabial muscle tension line group reconstruction. Design, Setting, and Participants From January 1, 2014, through June 31, 2015, a total of 6 patients with upper lip defect were treated with philtrum reconstruction in the same stage of the split cross-lip flap transfer at the Plastic Surgery Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College, Beijing, China. These patients underwent reconstruction of the philtrum by nasolabial muscle tension line group reconstruction. The patients were compared with a randomly chosen group of 5 individuals without upper lip defects by measuring the 3-dimensional scans. Interventions In the patient group, the split flap was elevated from the posterior portion of the oris orbicularis muscle after the inferior labial arteries were divided. Then the partial-thickness flap was rotated 180° horizontally and inverted 180° upward to the upper lip defect. The philtrum was reconstructed using the nasolabial muscle tension line group reconstruction. Main Outcomes and Measures Three-dimensional scans were performed from the 2-month to 28-month revisits. Results A total of 11 individuals were included in the study: 6 in the patient group (mean [SD] age, 17.0 [4.8] years; 2 [33.3%] female and 4 [66.7%] male) and 5 in the control group (mean [SD] age, 15.2 [6.0] years; 2 [40.0%] female and 3 [60.0%] male). In the patient group, 5 of 6 musculomucosal pedicle flaps were viable. A stable philtrum with philtral ridge and philtral dimple was reconstructed on the 5 flaps. The shape of the philtrum was natural according to the 3-dimensional scan measurement. One flap partially necrosed, and the scar retraction was severe postoperatively. Conclusions and Relevance The blood supply of the partial-thickness cross-lip flap was from the small vascular network of the lower lip. It is reliable to reconstruct a philtrum in this stage of flap transfer. A complete philtrum structure can be reconstructed by applying muscle tension on the flap. Level of Evidence 4.
