Cross Lip Vermilion Flap and Traumatic Upper Lip Avulsion: Reducing Donor Site Morbidity.

Using a cross lip vermilion flap for upper red lip reconstruction in cases other than whistle deformity in patients with cleft lip can lead to donor site morbidity. If the practitioner performs primary closure of the mucosa in lower vermilion after flap harvesting, the width and height of lower lip are reduced, which results in an increased lower incisor tooth show. Using free fat grafting is an effective method for reducing donor site morbidity in the lower lip following cross lip vermilion flap harvest.

Reconstruction of Multiple Lip and Facial Defects With Bipaddle and Sensate Radial Forearm Free Flap.

ABSTRACT: Free flaps and their modifications are used to reconstruct multiple large defects in the lip and face. In this study, we present our results on the reconstruction of these defects using bipaddle and sensate free radial forearm-palmaris longus flaps and subsequent revision surgeries. Patient medical records of 11 patients with a mean age of 63.9 ± 12.8 years were retrospectively reviewed. Functional oral competence, lip cosmetics, lip sensation, and donor forearm scars were evaluated using the drooling rating scale, visual analog scale, Semmes Weinstein Monofilament test, and patient and observer scar assessment scale, respectively. The mean dimensions of distal and proximal skin paddles of bipaddle free radial forearm-palmaris longus flaps were 12.7 ± 9.9 and 20.5 ± 3.8 cm2. Mean lengths of the bridge and proximal pedicles were 4.7 ± 1.6 and 5.5 ± 0.7 cm. All the flaps survived. No drooling was observed in the 2 patients without lower lip defects. The mean drooling scores of the 9 patients with lower lip defects were statistically different (Analysis of Variance, pANOVA < 0.00001) at 3, 6, 9, and 12 months postoperatively. The differences between 3 and 12 months were the most significant (pANOVA < 0.00001, pTUKEY < 0.000001). The lip sensation and drooling scores showed a strong positive correlation (r = 0.8504). All patients were able to speak fluently, drink fluid without leakage, and blow a balloon easily. All patients and observers were satisfied with the lip cosmetics, with no significant difference between satisfaction scores (P = 0.087615).There was a statistically significant difference (P < 0.00001) between mean sensation scores of surrounding healthy lip (2.94 ± 0.27) and free flaps (4.15 ± 0.4). All the donor scars healed uneventfully.

Case of eccrine chondroid syringoma of the upper lip.

Chondroid syringoma (CS) is a benign, slow-growing mixed tumour that arises from the sweat glands and usually presents in the head and neck area. Histopathological examination is important for proper diagnosis, as CS is often confused with epidermal cysts due to its rare presentation. This article presents a man in his 40s with a right upper lip mass that emerged 6 months prior to presentation. An intraoral surgical excision was performed and the histopathological analysis revealed solid epithelial cells that formed multiple, non-branching ducts lined by cuboidal epithelium. Cystic spaces were filled by heterogeneous eosinophilic material embedded in chondromyxoid stroma. Histopathology identified the lesion as an eccrine-variant CS. The patient recovered well.

Experience with 808-nm diode laser in the treatment of 47 cases of oral vascular anomalies.

Treatment of oral vascular anomalies (OVA) has focused on minimally invasive techniques rather than radical surgery. We investigated the efficacy and safety of diode laser using the photocoagulation technique in the management of OVA. Forty-seven subjects with OVA were treated with forced dehydration with induced photocoagulation (FDIP) using diode laser (808 nm/4.5 W). This series consisted mostly of male (63.8%) and non-white (63.8%) patients with a mean age of 57.4 years. Varices (91.5%), venous malformations (6.4%), and hemangiomas (2.1%) with a mean size of 7.1 (±4.9) mm were the conditions treated. OVA presented as a nodular lesion (63.8%) involving mainly the lower lip (46.8%). Pulsed laser mode was used as standard and the number of applications varied from one to four sessions, with the majority requiring only one (83%) FDIP session. Kaplan-Meier analysis revealed that complete clinical healing can occur on the 15th day (n=9/29.5%), followed by the 20th (n=6/45.5%), and 30th (n=7/70.5%) days. Postoperative edema was observed in 31 (66%) patients, and recurrence of the lesion occurred in two (4.2%). Based on the data on complete clinical healing, minimal patient discomfort, and satisfactory esthetic results, we can confirm that FDIP by diode laser is a promising candidate for the safe and efficacious treatment of OVA.

Full-thickness nasolabial facial artery flap: A modified surgical approach for reconstruction of lower lip defects.

OBJECTIVES: Reconstruction of large lower lip defects remains challenging in terms of aesthetics, function and safety. The aim of this study is to explore a modified nasolabial flap to repair large lower lip defects. METHODS: The full-thickness nasolabial facial artery flap was used for reconstruction of defects in lip squamous cell carcinoma (LSCC) patients after tumor ablation. The postoperative recovery of patients was obtained through clinical review and follow-up in the first and sixth month. RESULTS: There were four LSCC patients who received tumor ablation at the Beijing Stomatological Hospital of Capital Medical University from November 2022 to March 2023, were included in our study. All patients did not suffer from postoperative infection, orocutaneous fistula, flap necrosis, and flap loss. One patient had the trapdoor deformity. These patients achieved better lip closure function. One patient developed cervical lymph node metastasis 2 months after surgery. CONCLUSIONS: The modified nasolabial flap could achieve good outcomes in terms of aesthetics, function, and safety. It provided a supplementary strategy for the using of nasolabial flap in larger defects of lower lip.

Congenital midline upper lip sinus in an infant.

Congenital lip sinus is a rare entity with upper lip sinus being rarer than the lower lip sinus. It can be an isolated entity or associated with cleft lip, palate or Van der Woude syndrome. Syndromic association requires proper evaluation and aggressive surgical treatment. Preoperative delineation of the sinus tract with ultrasound sonography or MRI is mandatory. Simple excision is sufficient in cases of isolated sinuses. In this article, we report an infant with upper lip sinus managed successfully with simple excision and reviewed the literature.

Long-term results of orbicularis oris muscle reconstruction in primary cleft lip repair using the "basket-weave method".

The basket-weave method is an orbicularis oris muscle reconstruction method used in primary unilateral cleft lip repair. We compared the long-term results of the basket-weave method with those of a conventional method. For primary unilateral cleft lip repair, we compared the long-term results of 7 cases in which the orbicularis oris muscle was reconstructed by use of the basket-weave method, and of 7 cases in which the reconstruction was performed by use of the conventional method. The average postoperative follow-up period was 12 years and 7 months for the basket-weave method, and 11 years and 9 months for the conventional method. Using photographs of the front and elevation angle views, we evaluated the results as good if the philtrum ridge was formed on the fissure side and was almost symmetrical in height; as fair if the philtrum ridge was lower than the normal side; and as poor if the philtrum ridge had disappeared. For the basket-weave method, the results were good in 6 cases (85.7%), fair in 1 case (14.3%), and poor in 0 cases. For the conventional method, the results were good in 2 cases (28.6%), fair in 4 cases (57.1%), and poor in 1 case (14.3%). A significant difference was found between the 2 groups (Mann-Whitney U test, P = 0.0417). The philtrum ridge shape could be reconstructed by use of the basket-weave method, which gave better results in the long-term than did the conventional method for orbicularis oris muscle reconstruction in primary unilateral cleft lip repair.

A modified pull-through approach with a pedicled bone flap for oral and oropharyngeal cancer resection: a feasibility study.

PURPOSE: Compromised swallowing, speaking, and local complications are the major disadvantages of established approaches to the posterior tongue and oropharynx. The mandibular split involves an esthetically unpleasant bipartition of the lower lip and is prone to bony non-union or sequestration. The conventional pull-through technique on the other hand lacks the secure reattachment of the lingually released soft tissues. METHODS: The feasibility of a new modified pull-through approach was tested on three anatomical specimens. CAD/CAM cutting guides were used to design a retentive bone flap to properly refixate the genioglossus and geniohyoid muscles after the procedure. The radiographic assessment and treatment planning was performed on 12 cadavers. The entire procedure was tested surgically via dissection in three of those cases. This procedure was then applied in a clinical case. RESULTS: Precise repositioning and dynamic compression of bony segments was possible reproducibly and without injury to adjacent structures. In all dissected cases, a median lingual foramen was found and in two cases vessels entering it could be dissected Radiologic anatomical landmarks were sufficient in all 12 cases to perform the clinical planning procedure. Clinically, the osteotomized segment demonstrated good blood supply and plateless repositioning was verified postoperatively via cone beam scan. CONCLUSION: The method presented is safe and easy to perform. Individual cutting guides improve the safety and accuracy of the procedure, potentially eliminating the need for osteosynthesis. We provide the anatomical and radiologic basis for clinical evaluation of this pedicled bone flap procedure and present the clinical application of this modified pull-through approach.

A Novel Air-Cooled Nd:YAG Laser for the Treatment of the Venous Lakes of the Lips.

Objective: To evaluate the therapeutic effect of a novel air-cooled Nd:YAG laser in the venous lakes of the lips (VLL). Background: The thermal injury is one of the most important issues during laser therapy for venous lakes. Methods: Six pieces of fresh pork livers were used to provide 30 regions with a diameter of 6 mm for experiment in vitro, among which 15 regions were treated by Nd:YAG laser with air cooling until the tissue turned gray-white, whereas the rest were treated without air cooling as control. The operation time of laser irradiation, the degree of temperature increase, and the depth of coagulation tissue were compared between two groups. Then, 60 VLL patients were selected for Nd:YAG laser treatment with or without air cooling. The operation time of laser irradiation, the degree of temperature increase, the postoperative pain visual analog scale (VAS) score, and the percentage of lesions removed within 1 month were compared. Results: In tissue studies, the treated group showed a longer operation time of laser irradiation (p < 0.01), a lower degree of temperature increase (p < 0.01), and there was no significant statistical difference in the depth of coagulation tissue (p = 0.624). In clinical studies, the treated group showed a longer operation time of laser irradiation (p < 0.01), a lower degree of temperature increase (p < 0.01), and a lower VAS score on the 1st and 2nd day, compared with the control group (p < 0.01). Conclusions: Air cooling during Nd:YAG laser for the treatment of VLL can prolong the surgical time, but lowered tissue temperature and reduced patient pain within 2 days under the premise of ensuring the treatment effect.

Perioral Filler Augmentation.

Perioral tissues are among the first areas to show signs of facial aging, leading many patients to seek perioral fillers as their initial cosmetic treatment. These fillers offer a temporary solution by enhancing volume and reducing common facial lines. Various regions within the perioral area can be targeted, including the lips, nasolabial folds, philtral columns, vertical lip rhytids, oral commissures, melomental folds, mentolabial folds, and nasolabial folds. The technique for injecting perioral fillers depends on the specific region, chosen product, and the desired outcome of augmentation.

Enhancing the vermilion in adult secondary cleft lip repair with a continuous V plasty without closure of the donor defect-a case series.

The aim of this paper was to describe a modification to an old method to enhance the vermillion in adult cleft patients. We present ten consecutive patients who requested enhancement of the upper lip vermillion. The technique involves a continuous V plasty within the non-visible mucosa to elevate the vermillion. Each V incision is of a different size to match the defect. Then the V flaps are sutured to one another but the donor defect is left open to epithelialise. Adjunctive procedures are possible at the same time. There were no major complications but one patient was over corrected and needed reduction of mucosa. The technique offers a permanent enhancement of the vermillion and is a safe alternative to other methods of lip augmentation including fillers.

Investigation of the efficacy of two different laser types in the treatment of lower lip paresthesia after sagittal split ramus osteotomy.

Orthognathic surgery involves invasive and major surgical procedures commonly used to correct maxillofacial deformities. Bilateral sagittal split ramus osteotomy (BSSO) is often used to treat dentofacial anomalies related to the mandible, but it can result in various complications, the most common of which is inferior alveolar nerve damage. Nerve damage-induced paresthesia of the lower lip significantly affects patient comfort. Medical treatments such as steroids and vitamin B, low-level laser therapy (LLLT), and platelet-rich fibrin (PRF) can be used as supportive therapies for nerve regeneration after damage. This study aimed to investigate the effectiveness of two different types of lasers in treating lower lip paresthesia after BSSO. This clinical trial was a controlled, single-center, prospective, single-blind, randomized study. Thirty patients were included in the study and randomly assigned to three groups: Group I (laser GRR, n = 10) received transcutaneous and transmucosal GRR laser treatment, Group II (Epic10 laser, n = 10) received transmucosal and transcutaneous Epic10 laser treatment, and Group III (vitamin B, n = 10) received B-complex vitamin tablets orally once a day. Two-point and brush tests were performed six times at specific intervals, and a visual analog scale was used to evaluate pain and sensitivity. Both vitamin B and laser therapies accelerated nerve regeneration. The contribution of the laser groups to the healing rate was better than that of the vitamin B group. Although there was no statistically significant difference between the two laser groups, clinical observations indicated better results in the GRR laser group.

"Submarine-Shaped" Radial Forearm Flap for Simultaneous Reconstruction of Oral and Lower Lip Defects".

BACKGROUND: Reconstruction of the oral cavity commonly results in trismus and lip incompetence. AIM AND OBJECTIVES: In this study, we aim to describe an innovative design of a radial forearm free flap for resurfacing bilateral buccal defects and simultaneous functional lower lip reconstruction in a single stage. MATERIALS AND METHODS: Between January 2010 and December 2019, 6 males underwent simultaneous buccal and lower lip reconstruction with a radial forearm free flap. The mean age of the patients was 57.3 years (range, 50-68 years). The defects were caused by trismus release and due to previous treatments. The mean size of the defects was 17.9 cm in length and 3.25 cm in width. Flaps were harvested, including the proximal perforators of the radial vessels, and the inset began in the buccal area opposite the anastomosis side. RESULTS: Flap size ranged from 16 to 21 × 2 to 4 cm. The recipient vessels used were the superficial temporal (4) and facial (2). All flaps survived. Lip infection was seen in 2 cases and managed conservatively. The mean follow-up was 19.2 months (range, 12-28 months). The mean increase in the interincisal distance was 10.7 mm. Oral continence was good in all patients. Speech intelligibility was considered total in 4 patients and partial in the remaining 2. CONCLUSION: The radial forearm flap constitutes an option for simultaneous lower lip reconstruction and resurfacing of bilateral buccal areas after trismus release. The procedure provides a thin and pliable reconstruction using only 1 donor site and 1 set of recipient vessels.

Neuromodulator Injection for Gummy Smile.

SUMMARY: Neuromodulators have become a treatment of choice for the management of excess gingival show, or "gummy smile." There have been many proposed algorithms for the optimal placement and dosage of neuromodulator to inject in these locations. The authors aim to clarify these points and provide surgeons with a reliable way to manage the gummy smile that results from hyperactive muscles of the midface.

The Montreal Children's Hospital Experience Managing Robin Sequence: An Analysis of Outcomes and Algorithm for Surgical Technique Selection.

BACKGROUND: The development of mandibular distraction osteogenesis (MDO) and tongue-lip adhesion (TLA) has led to significant improvements in respiratory outcomes for the Robin sequence (RS) population. Despite such advances, there continues to be debate regarding management strategies. The authors present their experience managing the RS population with insights on technique selection. METHODS: A retrospective review of RS patients treated at the senior author's institution from 2003 to 2021 was conducted. Baseline patient demographics and clinical parameters including feeding and respiratory status were recorded. Outcomes included the need for tracheostomy or tracheostomy, decannulation rates, and feeding status. Patients were evaluated through overnight oximetry and drug-induced sleep endoscopy (DISE). Outcomes were stratified according to management technique (MDO, TLA, versus conservative) and compared through statistical analysis. RESULTS: Fifty-nine RS patients were included. Twenty-eight were managed conservatively, 19 underwent MDO, 10 underwent TLA, one underwent both TLA and MDO, and one underwent tracheostomy primarily. Overall, 1.7% of the cohort required a tracheostomy and 86% achieved oral feeding after the procedure. The MDO cohort had lower Apgar scores and mean birth weight compared with the conservative and TLA cohorts ( P < 0.05). There were no statistical differences in respiratory and feeding outcomes across all three cohorts. CONCLUSIONS: A therapeutic algorithm was developed with insight into the use of DISE and risk stratification with overnight oximetry to guide procedural selection. Using this approach, safe and satisfactory respiratory outcomes were achieved with a low tracheostomy rate. Risk stratification is possible without polysomnography, and DISE is a promising tool (that requires further validation) for procedural selection in this population. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.

Enhancing Philtrum Morphology Using Fat Grafting Combined with Percutaneous Rigottomy in Repaired Unilateral Cleft Lip.

BACKGROUND: Improving the philtrum morphology of patients with a secondary cleft lip deformity has been a challenge in cleft care. Combining fat grafting with percutaneous rigottomy has been advocated for treatment of volumetric deficiency associated with a scarred recipient site. This study assessed the outcome of synchronous fat grafting and rigottomy for improvement of cleft philtrum morphology. METHODS: Consecutive young adult patients ( n = 13) with a repaired unilateral cleft lip who underwent fat grafting combined with rigottomy expansion technique for enhancement of philtrum morphology were included. Preoperative and postoperative three-dimensional facial models were used for three-dimensional morphometric analyses including philtrum height, projection, and volume parameters. Lip scar was qualitatively judged by a panel composed by two blinded external plastic surgeons using a 10-point visual analogue scale. RESULTS: Three-dimensional morphometric analysis revealed a significant (all P < 0.05) postoperative increase of the lip height-related measurements for cleft philtrum height, noncleft philtrum height, and central lip length parameters, with no difference ( P > 0.05) between cleft and noncleft sides. The postoperative three-dimensional projection of the philtral ridges was significantly ( P < 0.001) larger in cleft (1.01 ± 0.43 mm) than in noncleft sides (0.51 ± 0.42 mm). The average philtrum volume change was 1.01 ± 0.68 cm 3 , with an average percentage fat graft retention of 43.36% ± 11.35%. The panel assessment revealed significant ( P < 0.001) postoperative scar enhancement for the qualitative rating scale, with mean preoperative and postoperative scores of 6.69 ± 0.93 and 7.88 ± 1.14, respectively. CONCLUSION: Synchronous fat grafting and rigottomy improved philtrum length, projection, and volume and lip scar in patients with repaired unilateral cleft lip. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.

Evaluation of Long-Term Outcomes of Transverse Facial Cleft Repair.

OBJECTIVE: To evaluate the long-term outcomes of linear commissuroplasty and linear skin closure with a focus on commissural migration. DESIGN: Retrospective study. PATIENTS: Individuals who underwent transverse facial cleft repair at a single institution between 2004 and 2021. INTERVENTIONS: The disrupted orbicularis oris muscle was reoriented and sutured. A simple linear commissuroplasty technique was used, and the cheek skin was closed linearly without Z-plasty. MAIN OUTCOME MEASURES: The distances from Cupid's bow peak to the oral commissure were measured bilaterally, and the difference between the normal and cleft sides was obtained. Finally, its proportional value as a percentage of the total lip length was calculated from short- and long-term follow-up photographs. Cheek scarring and its effects on melolabial fold breakage were evaluated. RESULTS: Of the 18 patients who underwent transverse facial cleft repair, 12 were included in this study. The mean follow-up period based on medical photographs was 1773.5 days. The average proportional difference was 4.6%, demonstrating no observable commissural migration. There were no consistent trends in the direction of migration, either on the cleft or normal side. In patients with a transverse cleft crossing the melolabial fold, the folds appeared broken before and after the cleft repair surgery. CONCLUSIONS: No significant long-term commissural migration was observed after transverse facial cleft repair with simple linear commissuroplasty and linear skin closure. Deliberate positioning of the new oral commissure, proper myoplasty, and meticulous skin closure with minimal scar burden can be considered key procedures for successful transverse cleft repair.

Nasal Sill Flap for Lip Lifting.

BACKGROUND: Over the years, different techniques have been developed to reduce the number of incisions and scars in subnasal lip lifting and to increase the amount of lifting. The aim of this study was to present a new technique to hide the scars at the nasal base in subnasal lip lifting procedures and to review the literature. METHODS: The file of patients who underwent subnasal lip lifting between January 2019 and January 2021 were examined. In all patients, the nasal sill flap that was designed was elevated, and the nasal sill flap that was prepared was adapted to its new location when the excision had been completed. Two different plastic surgeons evaluated the patients in the postoperative 12-month follow-ups. The scars were evaluated for vascularity, pigmentation, elasticity, thickness, and height. RESULTS: The study included 26 patients. While 21 patients had no histories of lip lifting, five patients had had previous lip lifting history. The mean operation time was 37.11 minutes. Patients' skin types were determined as Type 3 in 18 patients and Type 4 in eight patients according to the Fitzpatrick classification. The mean follow-up period of the patients was 13.11 months. At the end of the 12-month period, the mean scar score of the patients was calculated as 11.15. The mean scar score of primary cases was 11.14, and the mean scar score of secondary cases was 11.20 (p = 0.983). There was no statistically significant difference in terms of complications among smokers (p = 0.356). The mean scar score was calculated as 12.17 in patients who had Type 3 skin and 8.88 in patients with Type 4 skin (p = 0.075). CONCLUSIONS: This technique is beneficial for patients because the scars are discrete and easier for patients to accept.

Endoscopic Temporalis Tendon Extension (ETTE).

Many techniques have been proposed to restore facial symmetry in facial nerve palsies. This study presents our surgical approach called Endoscopic Temporalis Tendon Extension (ETTE). After nasotracheal intubation, a 4 cm skin incision is made at the nasolabial fold. Under endoscopic view, the medial face of the masseter muscle is detached from the mandibular ramus. The coronoid process is then sectioned by Piezosurgery®. Finally, a fascia lata graft is suspended between the temporalis tendon and the orbicularis oris. ETTE is a mixed technique, with a static suspension component and a dynamic contraction one. The preservation of the temporalis muscle insertion in temporal fossa allows for an optimal contraction. A fascia lata graft is necessary for reasons of length. The scar produced by the nasolabial incision allows to recreate the missing nasolabial fold. The endoscopic assistance provides greater precision during the procedure and entails a shorter learning curve.

Abnormal Rhomboid Lip and Choroid Plexus Should be Valued in Microvascular Decompression for Vestibulocochlear Diseases.

BACKGROUND: Surgical outcomes for functional vestibulocochlear diseases vary, and the influencing factors are not fully understood. The role of a rhomboid lip (RL) and choroid plexus (CP) in microvascular decompression (MVD) of the vestibulocochlear nerve has not been studied. This study aims to evaluate the surgical efficacy of MVD for vestibulocochlear diseases, with and without addressing the RL and CP, to enhance our understanding of their etiology. METHODS: A total of 15 patients who underwent MVD for the vestibulocochlear nerve between 2013 and 2022 were retrospectively identified and followed up. The patients were classified into 4 categories: vestibular paroxysmia (VP), benign positional paroxysmal vertigo (BPPV), and Meniere disease (MD). The fourth was a "tinnitus" group. The relief of symptoms, recurrence, satisfaction after surgery, available relevant imaging studies, and intraoperative observation data were evaluated. RESULTS: Following MVD, 6 of the 7 patients in the VP group, the 1 patient in the BPPV group, and 1 of 2 patients in the MD group were completely relieved of vertigo. The seventh VP patient showed significant improvement. The 5 patients in the "tinnitus" group remained unchanged. Retrospectively, 4 patients from the VP, BPPV, and MD groups who underwent RL incision and CP excision were also free of vertigo, although vascular compression was not confirmed in these cases. CONCLUSIONS: MVD is generally considered a useful treatment for VP and could also be effective in managing recurrent vertigo caused by BPPV and MD. Our results highlight the potential role of an abnormal RL and CP in the development of vertigo symptoms. Patients presenting with "tinnitus" require further investigation and might not be suitable for MVD.
