Abdominal Dermal Fat Graft Versus Nasolabial Flap in Oral Submucous Fibrosis: A Randomized Clinical Trial.

Introduction: A prospective study was conducted to find out an effective alternative in the form of non-vascularized abdominal dermal fat graft (ADFG) and to compare its efficacy with the vascularised nasolabial flap (NLF) for the treatment of oral submucous fibrosis (OSMF). Method: Comparative study comprising of 30 patients with Grade 3 and 4A OSMF, randomly divided into 2 groups: Group A (ADFG) and Group B (NLF). They were evaluated for mouth opening (MO), graft uptake, time taken for mucosalization, pain, intercommissure distance (ICD), scar, duration of surgery (DOS), patient satisfaction and thickness of masseter muscle on ultrasonography. Findings: At 6 months, MO improved by 22.4 and 36.2 mm in Group A and Group B, respectively. There was statistically significant difference (p < 0.05) seen for the values between the groups for all the parameters except for ICD and VAS score, which was statistically insignificant (p > 0.05). Intraoral hair growth, facial scar, orocutaneous fistula and commissure tear was seen in Group B. Complete necrosis of graft followed by recurrence was seen in three cases in Group A. Conclusion: NLF holds better as compared to ADFG in the management of OSMF. However, the cornerstone of success remains habit cessation and aggressive physiotherapy. The limitations of the study are small sample size and short duration of follow-up.

A Retrospective Study Comparing the Surgical Results of Platysma Myocutaneous Flap, Buccal Pad of Fat, and Nasolabial Flap for Reconstruction After Fibrotomy in Cases of Oral Submucous Fibrosis.

PURPOSE: To evaluate the effectiveness of nasolabial flap (NLF), a buccal pad of fat flap (BFP), and platysma myocutaneous flap (PMF) for reconstruction following fibrotomy for individuals with oral submucous fibrosis (OSMF). MATERIAL AND METHOD: A retrospective study was conducted among patients diagnosed with grade III and IV OSMF in the Department of Oral and Maxillofacial Surgery at Sharad Pawar Dental College between January 2016 and August 2018. The essential patient information was obtained from the Medical Record Department (MRD) at Acharya Vinoba Bhave Rural Hospital (AVBRH), Datta Meghe Institute of Medical Sciences (DMIMS) Sawangi (Meghe) Wardha. The patients were categorized into three groups: the NLF, the BFP, and the PMF groups. Each group had 16 patients, and factors such as interincisal width, diminished burning sensation in the mouth, inter-commissure distance, and flap necrosis were compared pre- and post-operatively. Student's unpaired t-test and chi-square test were employed for statistical analysis. RESULT: Mean interincisal mouth-opening increased from pre-operative 4.79 to 41.42 mm post-operatively in the NLF group, BFP group from 6 to 39.42 mm and in the PMF group from 9.26 to 39.34 mm with p value=0.0001. NLF group showed complete and partial resolution of the burning sensation of the mouth at 93.75% and 6.25%, BFP at 62.25% and 32.75% while in PMF it was 68.5% and 31.25% respectively. One year postoperatively 3.28 mm increase in inter-commissure width was observed in the NLF group with a marginal increase in the PMF group and a negligible increase in the BFP group. 18.75% partial flap necrosis was seen in BFP, 18.75% in the PMF group, and 6.25% in the NFL group. CONCLUSION: All the flaps are efficacious in treating OSMF, however, NLF stands ahead with its higher reliability owing to its excellent blood supply.

Systematic review of minimally-invasive reconstructive options for oral cavity defects.

The oral cavity is a primary site for malignant neoplasms of the head and neck region. Surgery, with or without adjuvant therapy, offers the highest probability of cure by focusing on radical tumour removal and organ function restoration. Reconstructive options are represented by local and free flaps, while small defects can be managed without reconstruction. For medium-sized defects without bone involvement, local flaps can be a good alternative to free flaps in selected patients. The purposes of this article are to analyse the main minimally-invasive reconstructive techniques in oral cancer surgery through a systematic review of the literature and develop a reconstructive algorithm based on the site and size of the defect. We defined minimally-invasive reconstruction as any reconstructive option not involving flap dissection from the neck or other distant areas from the oral cavity. Options considered include: local myo-mucosal or mucosal flaps (based on the facial or buccal arteries, and palatal flap), Bichat's fat pad flap, and nasolabial flap. Use of biological or synthetic materials is also described. In selected patients with small to moderate-sized defects, the possibility of reconstruction with local flaps can be a viable option.

Reconstructive Options for Basal Cell Carcinoma Defects in the Head and Neck Region: An Institutional Experience.

Basal cell carcinoma (BCC) is the most common skin cancer with more than 80% occurring on the face occurring mainly due to exposure to ultraviolet rays in the elderly due to cumulative exposure of the UV rays during their lifetime. Though various treatment modalities are available for the treatment of basal cell carcinomas, wide local excision is the standard line of management. However, reconstruction of facial BCC poses a challenge to the reconstructive surgeon. Over a 4-year-old period from 2017 to 2021, a total of 30 patients of head and neck basal cell carcinoma were surgically excised in our institution. We have explored all modes of reconstruction from small to large BCC defects in terms of cosmesis, form and function. Four patients underwent primary closure, 8 patients underwent skin grafting, 13 patients underwent closure by local and advancement flaps and 5 patients with large defects underwent free flap reconstruction. No flap loss was reported. None reported any functional deficit. To achieve adequate aesthetic surgical outcomes after reconstruction, knowledge of facial aesthetic regions is of utmost importance. The size and location of the defect and the presence of vital structures adjacent to the defect should be assessed to determine the kind of reconstruction that should be carried out without adversely affecting adjacent structures. For greater patient satisfaction, the method of reconstruction should be tailor made, where donor tissue resembles native tissue with good contour and texture match, suture line scars are camouflaged, and complications are nil.

Experience of Island Nasolabial Flap for Patients with Oral Cavity Cancer.

Aim: To find out the utility of the island nasolabial flap in patients with oral cavity malignancy. Materials and methods: This was an observational study conducted at a super-specialty hospital in Maharashtra from October 2019 to December 2021. Patients with oral malignancy planned for island nasolabial flaps were only considered. Results: A total of 20 patients were operated on, out of which 16 were males and 4 were females. All the patients were followed up for a minimum period of 6 months. The hospital's online reporting system is used for the data collection including the post-operative assessment. Out of the 20 patients, 10 patients were suffering from tongue carcinoma, 6 patients from buccal mucosal carcinoma, two from hard palate carcinoma and one patient each from the floor of the mouth and lip carcinoma. The mean age of the series was 52.3 years, the average duration of the surgery is 169.4 min and the average hospital stay in the series was 4.35 days. The Ryle's tube was removed on an average of 4.35 days. No flap-related complications were noted during the series, and healing of the donor site was uneventful. The functional outcomes after the reconstruction are acceptable in all the cases except in the lip reconstruction patient where there was post-operative drooling. Conclusion: The island nasolabial flap is relatively easy to harvest and less time-consuming. The other advantages include the post-operative surgical scar falls along the nasolabial fold, long pedicle length with preservation of the facial pedicle for future microvascular use, early transfer to the oral feed from the nasogastric feed, and early de-cannulation. In our small study, we observed that the island nasolabial flap is a very useful flap for the small to moderate-sized defects of the oral cavity. We feel, one of the disadvantages of this flap is that it is not an ideal flap for lip reconstruction.

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.

Comparative evaluation of nasolabial flap and buccal fat pad flap in the surgical management of oral submucous fibrosis: a systematic review and meta-analysis.

PURPOSE: Oral submucous fibrosis (OSMF) is a chronic, potentially malignant condition affecting any part of the oral cavity and is prevalent in Southeast Asia and the Indian subcontinent. The aim of this study is to compare the efficacy of buccal fat pad flap with the nasolabial flap in the management of OSMF. METHODS: We systematically compared two commonly used constructive techniques in the management of OSMF: the buccal pad of fat flap and the nasolabial flap. We performed a comprehensive search in four databases for all articles published between 1982 and November 2021. We assessed the risk of bias using the Cochrane Handbook and Newcastle-Ottawa Scale. We used the mean difference (MD) for pooling the data with 95% confidence intervals (CIs) and evaluated the heterogeneity between pooled studies using χ2 and I2 tests. RESULTS: Out of 917 studies, six were included in this review. The meta-analysis significantly favored conventional nasolabial flap over buccal fat pad flap in improving the maximal mouth opening (MD, - 2.52; 95% CI, - 4.44 to - 0.60; P = 0.01; I2 = 0%) after OSMF reconstructive surgery. Conversely, when it comes to esthetic outcomes, these studies favored buccal fat pad flap. CONCLUSION: Our meta-analysis found that nasolabial flap was better than buccal fat pad flap in terms of mouth opening restoration after OSMF reconstructive surgery. Also, the included studies found better results, favoring nasolabial flap over buccal fat pad flap in terms of oral commissural width restoration. Also, these studies reported better outcomes in terms of esthetics, favoring buccal fat pad flap. Further studies with larger sample sizes and different populations/races are needed to confirm our findings.

A New Algorithm for Secondary Repair of Unilateral Cleft Lip Nasal Deformity.

OBJECTIVES: Following primary surgery for unilateral cleft lip palate (UCLP), cleft lip nasal deformities (CLNDs) (nasal asymmetry, collapsed nasal alae, and a widened alar base) are generally inevitable and often require secondary rhinoplasty. However, reconstructing a cleft nose with an alar tissue deficiency remains challenging for rhinoplasty surgeons. METHODS: The manifestations of common deformities are described herein, and a secondary rhinoplasty technique for unilateral CLNDs using a nasolabial flap (NLF) has been proposed for patients with alar tissue deficiency. Secondary rhinoplasties were performed in 12 patients with unilateral CLNDs between 2020 and 2021 using a NLF. Photogrammetric measurements were performed preoperatively and postoperatively. A total of 12 flaps were successfully transferred. Ten patients were followed up for >1 year. RESULTS: Significant postoperative decreases in nasal alar width were measured in both the base view (p < 0.050) and the frontal view (p < 0.050). Despite the additional facial scars that occurred in some cases, all patients were satisfied with the aesthetic effects. CONCLUSIONS: The NLF achieved satisfactory results in secondary rhinoplasty of unilateral CLND for patients with nasal tissue deficiencies in whom the surgeon weighed the potential benefits over postoperative scarring. LEVEL OF EVIDENCE: 4 Laryngoscope, 134:1648-1655, 2024.

Comparative Evaluation of Nasolabial Flap, Buccal Fat Pad and Platysma Myocutaneous Flap for Reconstruction of Oral Sub Mucous Fibrosis Defects.

Moderately advanced (stage III) and advanced (stage IV a & b) OSMF requires surgical intervention for management A number of options are available for reconstruction of post OSMF oral cavity defects. In our study we retrospectively compared buccal fat pad, nasolabial flap and platysma flap for reconstruction of the buccal mucosal defects. Patient records were obtained from the medical records section of the Institute and divided into three groups; group A (buccal fat pad), group B (nasolabial group) and group C (platysma flap). Maximal mouth opening and intercommisural distance were the primary outcomes. Kruskal Wallis test was used to test the mean difference between three groups. Mann-Whitney test was used for intergroup comparisons. Wilcoxon signed rank test was used to evaluate the mean difference in outcomes at each follow up interval. A p value of < 0.05 was considered as statistically significant at 95% confidence interval. After 1 year follow up patients in platysma group had significantly better mouth opening (39.84 ± 1.65 mm) compared to both buccal fat pad (36.69 ± 3.41 mm) and nasolabial groups (37.94 ± 0.43 mm). Inter commisural distance was significantly better in patients reconstructed with platysma flap (59.21 ± 0.99 mm) compared to both buccal fat pad (54.11 ± 1 mm) and nasolabial flap (56.84 ± 1.48 mm). Platysma flap lead to significantly better maximal mouth opening compared to both nasolabial and buccal fat pad. Both buccal fat pad and nasolabial lead to comparable mouth opening. Inter commissural distance is maximum with platysma flap followed by nasolabial flap and buccal fat pad.

Utility of Single-Stage Nasolabial Flap Reconstruction for Oral Cavity Defects Following Surgery for Oral Cancers and Premalignant Lesions: A Clinical Audit.

An inferiorly based nasolabial flap (NLF) is a versatile flap for various oral cavity defects. However, it generally necessitates a second stage procedure to release the base at 3 weeks following the initial surgery. Reconstruction for oral cavity defects can be done with the inferiorly based nasolabial flap as a single-stage procedure. In this retrospective clinical audit, we analyzed patients who underwent an inferiorly based NLF reconstruction for oral cavity defect from January 2016 to September 2021. We analyzed the various defects for which this flap was used along with the associated complications and the safety of performing this flap in terms of its flap-related complications and the histopathological features such as margins. Forty-four patients underwent this inferiorly based single-stage NLF. The median age of the patients in the cohort was 56 years, with the majority being men (n = 38, 86.4%). Buccal mucosa and lip were the most common sites of the primary. Twenty-nine patients were per primam and 15 were recurrent cancers. Most had T1 (n = 14, 31.8%) and T2 (n = 19, 43.2%) cancers. The median closest margin was 6 mm and the base was 7 mm. There were no flap losses; however, 6 patients had minor wound breakdown for which secondary suturing was needed. Single-stage NLF is a safe flap that could be considered in select patients for appropriate oral cavity defects.

[Application of bilateral facial perforator artery flap in repairing large area defect in middle and lower part of nose].

Objective: To investigate the feasibility and effectiveness of bilateral facial perforator artery flap in repairing large area defect in middle and lower part of nose. Methods: The clinical data of 18 patients with large area defect in middle and lower part of nose repaired by bilateral facial perforator artery flap between January 2019 and December 2022 were retrospectively analyzed. Among them, there were 13 males and 5 females, the age ranged from 43 to 81 years, with an average of 63 years. There were 3 cases of nasal trauma, 4 cases of basal cell carcinoma, 8 cases of squamous cell carcinoma, 1 case of lymphoma, and 2 cases of large area solar keratosis. The size of the defect ranged from 3.0 cm×3.0 cm to 4.5 cm×4.0 cm; the size of unilateral flap ranged from 3.0 cm×1.3 cm to 3.5 cm×2.0 cm, and the size of bilateral flaps ranged from 3.3 cm×2.6 cm to 4.5 cm×4.0 cm. Results: One patient developed skin flap necrosis after operation, and a frontal skin flap was used to repair the wound; 1 case gradually improved after removing some sutures due to venous congestion in the skin flap, and the wound healing was delayed after dressing change; the remaining 16 cases of bilateral facial perforator artery flaps survived well and all wounds healed by first intention, without any "cat ear" malformation. All 18 patients had first intention healing in the donor area, leaving linear scars without obvious scar hyperplasia, and no facial organ displacement. All patients were followed up 3-12 months, with an average of 6 months. Due to the appropriate thickness of the flap, none of the 18 patients underwent secondary flap thinning surgery. All flaps had good blood circulation, similar texture and color to surrounding tissues, symmetrical bilateral nasolabial sulcus, and high patient satisfaction. Conclusion: The bilateral facial perforator artery flaps for repairing large area defect in middle and lower part of nose can achieve good appearance and function, and the operation is relatively simple, with high patient satisfaction.

Management of Oral Sub Mucous Fibrosis Using Three Different Flaps: Superficial Temporal, Nasolabial Flap, Buccal Fat Pad Flap Along with Active Physiotherapy- A Comparative Study.

To assess the efficacy of different flaps along with active physiotherapy for comprehensive management of OSMF. A total of 33 patients of oral submucous fibrosis were admitted and surgically treated. All patients were diagnosed with bilateral oral submucous fibrosis of buccal mucosa. All the patients had advanced oral sub mucous fibrosis with interincisal distance less than 20 mm. Eleven patients were treated with buccal pad of fat, eleven with nasolabial flap and eleven patients were treated with temporo-parietal fascia flap. Physiotherapy was started from the 5th postoperative day and the patients were followed regularly for one year to measure maximum interincisal distance. There was a significant corelation between post-operative mouth opening and regular physiotherapy, exercise and quitting of the habit irrespective of type of reconstruction flap used. On the basis of the result obtained from this study, significant improvement in mouth opening was seen in patients who performed aggressive physiotherapy irrespective of the flap used. Thus we conclude along with the surgical treatment, post-operative physiotherapy and cessation of habit are of equal importance for good prognosis in OSMF patients.

Nasolabial Flap in the Management of Oral Sub Mucous Fibrosis: A Series of Cases.

The objective of this study was to evaluate the outcomes of the nasolabial flap in the management of oral submucous fibrosis (OSMF). The descriptive case series included 75 patients diagnosed with OSMF who underwent surgical intervention under general anesthesia. Preoperative mouth opening measurements were compared with postoperative measurements taken after 2 months. Regarding mouth opening, out of the 75 patients, 4 (5.3%) had unsatisfactory results after treatment, while 22 (29.3%) experienced satisfactory outcomes. The majority of patients, 49 (65.3%), achieved normal mouth opening (more than 30 mm) following the Nasolabial flap procedure. This indicates that the Nasolabial flap yielded favorable results in terms of restoring normal mouth opening and benefiting the patients. Based on the findings of this study, the Nasolabial flap was determined to be a viable surgical option for managing oral submucous fibrosis due to its ease of operation, reliable flap vascularity, and low post-operative complication rate. The only drawback identified was the presence of a surgical scar, which can be addressed through secondary correction procedures.

Treatment Challenges in Soft Tissue Reconstruction in Patients With MRONJ - The Nasolabial Flap.

BACKGROUND/AIM: Antiresorptive drugs (e.g., bisphosphonates, denosumab) are crucial in the treatment of oncological diseases. However, these antiresorptive drugs can cause medication-related osteonecrosis of the jaw (MRONJ). MRONJ is a challenging disease regarding the soft tissue defect treatment. There are various surgical reconstruction techniques. One of them is the nasolabial flap. CASE REPORT: The present case report describes a 76-year-old female suffering from MRONJ leading to a progressive abscess of the mandible as well as an intra/extraoral fistula with extent to the chin region. Surgical splitting of the abscess was performed immediately. In the further course, a surgical decortication of the mandible with soft tissue defect treatment using a mucoperiosteal flap was performed. Intraoperatively, the bone of the mandible showed severe necrotic defects in multiple locations. Therefore, a continuity resection of the mandible with an insertion of a reconstruction plate was performed. Postoperatively, however, there was a progressive wound dehiscence. Due to the persisting regression of the gingival mucosa, the soft tissue defect was treated with a caudally pedicled bilateral nasolabial flap. The further clinical follow-up showed no recurrence of MRONJ with a well-healed nasolabial flap. CONCLUSION: In addition to mucoperiosteal flaps and microvascular reconstructions, the nasolabial flap can be a sufficient surgical therapy for intraoral soft tissue defect reconstruction.

Local Random Pattern and Axial Flaps for Reconstruction of Nasal Surgical Defects: Retrospective Analysis with an Attempt to Inspire ENT Surgeons.

Aim: Reconstruction of the surgical defects of the external nose has been challenging and largely considered to be the domain of plastic reconstructive surgeons. The present study aims to share our experience in reconstructing such defects. Materials and methods: A retrospective analysis of 11 patients who underwent external nasal reconstruction secondary to surgical defect at our otolaryngology department in a tertiary care hospital from 2017 to 2019 was done. All the patients underwent surgical excision of a part of the external nasal dorsum followed by reconstruction by our team of otolaryngology surgeons using local random pattern/ axial flaps. The patients were followed up postoperatively for a period ranging from 3 months (for benign pathologies) to 2 years (malignant pathologies). Results: The flaps were taken up in all the patients. Minor complications like postoperative infection were seen in 2 cases, resulting in wound dehiscence in one that required resuturing that was uneventful. The appearance was bulky in all the patients, although the patients were satisfied with the overall cosmetic appearance. The average hospital stay was 2 to 4 days. Conclusion: Reconstruction of external nasal surgical defects is a challenging task. Thorough knowledge of relevant anatomy, proper planning, and availability of abundant vascularized donor tissue in the near vicinity of the defect makes this challenge acceptable with good outcomes even in the hands of otolaryngologists.

Versatility of Naso-labial Flap in Reconstruction of Facial Defects.

Background: Reconstruction of facial defects is often challenging and is dependent on numerous factors including size of the defect, availability of donor site, any existing scar, patient's consent, prognosis, etc. There are various reconstruction modalities highlighted in the literature with their inherent merits and demerits. Considering the versatility of nasolabial flap, we present a case series of different facial defects where nasolabial flap has been used successfully for reconstruction. Case Reports: Three patients with different disease process in three different areas of face were reported. All underwent wide local excision and reconstruction with nasolabial flap. The result obtained was esthetically pleasing with minimal donor site morbidity. Conclusion: Nasolabial flap is a versatile flap and can be effectively used for reconstruction of small to moderate facial defects over any other flaps.

Effectiveness of Nasolabial Flap Versus Paramedian Forehead Flap for Nasal Reconstruction: A Systematic Review and Meta-analysis.

BACKGROUND: Different studies performed on nasal subunit reconstruction by either the nasolabial flap or the paramedian forehead flap have reported contradictory outcomes and complications, claiming one flap or the other as superior. This inconsistency has led to a gap in existing literature regarding the preferable flap for nasal reconstruction. Our aim was to statistically evaluate and compare these two flaps for nasal reconstruction, in terms of subunit preference, complications, and outcomes, using data from previous studies. METHODS: This systematic review is reported using PRISMA protocol and was registered with the International prospective register of systematic reviews. The literature search was done using "paramedian forehead flap", "nasolabial flap", "melolabial flap", "nasal reconstruction". Data regarding demography of study and population, subunit reconstructed, complications, and aesthetic outcomes were extracted. Meta-analysis was performed using MetaXL and summary of findings using GRADEpro GDT. RESULTS: Thirty-eight studies were included, and data from 2036 followed-up patients were extracted for the review. Meta-analysis was done on data from nine studies. Difference in alar reconstruction by forehead versus nasolabial flap is statistically significant [pooled odds ratio (OR) 0.3; 95% CI 0.01, 0.92; p = 0.72; I2 = 0%, n = 6 studies], while for dorsum and columella reconstruction the difference is not statistically significant. Risk of alar notching is marginally more in forehead flap, however difference in incidence of partial/complete flap necrosis, alar notching and hematoma/bleeding among the flaps is not statistically significant. CONCLUSION: Alar reconstruction is preferred by nasolabial flap. Complications are similar in both groups. Comparison of aesthetic outcome needs further exploration.
