Algorithm for the treatment of oral and peri-oral defects through local flaps

Oral Reconstruction with Locoregional Flaps after Cancer Ablation: A Systematic Review of the Literature

Introduction: The planning of oral reconstruction after tumor resection is a pivotal point for head and neck surgeons. It is mandatory to consider two aspects: the size of the surgical defect and the complexity of the oral cavity as an anatomical region. We offer a review of the literature that focuses on four types of locoregional flaps that can be profitably used for such reconstruction: infrahyoid (IF), nasolabial (NF), platysma (PF), and submental (SF). Methods: The study was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. This systematic review was carried out according to the PICOS acronym through a comprehensive electronic search on PubMed/MEDLINE, Cochrane Library, and Google Scholar databases. For each selected article, we extrapolated eight main parameters, of which all mean values were compared through an ANOVA test. The dimensions of the oral defects were referred to as "small" (<7 cm2), "medium" (7-50 cm2), or "large" (>50 cm2). Results: A total of 139 articles were selected with a total of 5898 patients. The mean ages for each type of flap were not statistically significant (p = 0.30, p > 0.05). Seven sublocations of oral defects were reported: The most common was the tongue (2003 [34.0%] patients), followed by the floor of the mouth (1786 [30.4%]), buccal mucosa (981 [16.6%]), cheek (422 [7.2%]), hard palate (302 [5.1%]), alveolar ridge (217 [3.7%]), and retromolar trigone (187 [3.2%]). The defects were mainly medium-sized (4507 [76.4%] patients), and fewer were small-sized (1056 [17.9%]) or large-sized (335 [5.7%]). Complications were noted, the most frequent of which was flap necrosis, seen in 0.57% of cases. The functional and esthetical results were mainly positive. Conclusions: Locoregional flaps represent a good alternative in medium-sized defects as well as a fairly good alternative in small- and large-sized defects when other options are ruled out.

Prevention and treatment of microstomia

The mouth, located in the lower third of the face, is a uniquely visible structure. It serves as a vital organ both aesthetically and functionally, playing a key role in speech, expression, and fundamental oral functions. Consequently, any alterations or defects in its shape, due to various causes, can lead to aesthetic and functional deficiencies. These issues may also result in challenges with social interactions and a decrease in confidence. In cases of microstomia, various surgical approaches are proposed based on the location, extent, shape, and cause of the defect, leading to numerous case reports. Plastic surgeons are proficient in oral reconstruction; however, cases of microstomia are relatively rare, which reduces their familiarity and interest in these cases. Additionally, preferences for oral size and shape vary according to factors such as geographical region and ethnicity, further complicating the functional definition of microstomia. Therefore, both subjective patient and physician judgments play crucial roles in the diagnosis and treatment of microstomia, as these may vary depending on individual and societal aspects. This review aims to classify the various causes and definitions of microstomia, as well as its non-surgical and surgical treatment options, with the goal of the treatment of this condition.

Medium-sized buccal mucosa defect reconstruction with buccal advancement flap in mucoepidermoid carcinoma ex pleomorphic adenoma: a case report

Introduction and importance

Mucoepidermoid carcinoma (MEC) ex pleomorphic adenoma is a rare type of salivary gland cancer. Surgical resection remains the standard therapy for this malignancy. After tumor removal, larger defects may require a local, regional, or free flap, while smaller ones can be closed primarily. Managing medium-sized defects can be challenging, especially on the buccal mucosa.

Presentation of case

A 47-year-old man had a buccal mucosa mass for 10 years, which gradually grew over a year and irritated his chewing. A 2.2×2 cm buccal mass was observed with telangiectatic and erythematous alterations in the surrounding mucosa. The preoperative tissue biopsy suggested salivary gland malignancy. The patient underwent surgical excision and a single-stage buccal advancement flap reconstruction, successfully closing the 4 cm defect. The final diagnosis was MEC ex pleomorphic adenoma. He reported mild discomfort during the first few months while opening his mouth. The patient had fully recovered after 6 months.

Clinical discussion

This is the first case of MEC arising in a pleomorphic adenoma of the buccal mucosa. For low-grade and small-sized tumors, a single modality is appropriate for treatment. Local flaps such as buccal fat pad or musculomucosal flap can repair medium-sized defects. However, the buccal advancement flap provides effective functional and esthetic benefits, optimal healing conditions, and reduces complications risk.

Conclusion

The buccal advancement flap is a valuable option for reconstructing medium-sized buccal defects up to 4 cm. The single-stage surgical procedure has been proven to yield minimal complications and provide a favorable outcome.

Single-Stage Peninsular-Shaped Lateral Tongue Flap for Personalized Reconstruction of Various Small- to Moderate-Sized Intraoral Defects: A Retrospective Case Series with Tongue Function Evaluation Using the Functional Intraoral Glasgow Scale

Herein, we present our experience using a single-stage peninsular-shaped lateral tongue flap (pLTF) to cover various intraoral defects and confirm the versatile utility and effective application of pLTF in intraoral defect reconstruction. This study included eight cases (six males and two females; average age 60.3 ± 16.9 years) of intraoral defect reconstruction performed by a single surgeon between August 2020 and May 2023 using the single-stage pLTF technique. Electronic medical records and photographs of the patients were collected and analyzed. The functional intraoral Glasgow scale (FIGS) was used to evaluate preoperative and postoperative tongue function. Defect sizes ranged from 3 cm × 3 cm to 4 cm × 6 cm. Notably, all defects were successfully covered with pLTFs, and the flap sizes ranged between 3 cm × 4.5 cm and 4.5 cm × 7.5 cm. The flaps completely survived without any postoperative complications. At follow-up (average, 9.87 ± 2.74 months), no patient had tumor recurrence or significant tongue functional deficits. The mean preoperative and postoperative FIGS were 14.75 ± 0.46 and 14.00 ± 0.92, respectively (p = 0.059). Thus, the single-stage pLTF technique is a good reconstructive modality for various small to moderate intraoral defect coverage in selected cases for personalized intraoral reconstruction.

Clinical comparison of superior thyroid artery perforator flap and sternocleidomastoid myocutaneous flap for intraoral reconstruction

The aim was to evaluate the techniques and outcomes of superior thyroid artery perforator flaps (STAPF) for intraoral reconstruction and to compare them with those of the sternocleidomastoid myocutaneous flap (SCMMF). The cases of 43 patients who underwent reconstruction with either a SCMMF or STAPF for the repair of a medium-sized intraoral defect, between January 2013 and December 2020, were reviewed retrospectively. Although both flaps are based on the superior thyroid artery, their specific harvesting techniques largely differ. All SCMMF (n = 23) were superiorly-based rotational flaps with myocutaneous designs. The STAPF cases (n = 20) included 18 septocutaneous flaps and two chimeric flaps. The flap size was larger in the STAPF group (P = 0.008), while incomplete level IIB dissection (oncological safety) was more frequent in the SCMMF group (P = 0.002). The flap necrosis rate was lower in the STAPF group (STAPF 15% vs SCMMF 34.8%, though this was not statistically significant). Cox multivariate analysis showed that the postoperative flap outcome (total flap necrosis vs flap survival; hazard ratio 27, 95% confidence interval 2.149-336.05; P = 0.001) and complications (excluding fistula) (hazard ratio 14, 95% confidence interval 1.314-142.767; P = 0.029) were associated with overall patient survival. Both speech (P < 0.001) and neck mobility (P < 0.001) functions were superior with STAPF reconstruction. Compared with the traditional SCMMF, the STAPF was found to have a lower necrosis rate with uncompromised oncological safety during harvesting. The STAPF is a good alternative for the repair of medium-sized head and neck defects.

Management of Palatal Defects after Free-Flap Reconstruction and Radiotherapy

Palatal fistulas have significant effects on quality of life. Traditional prosthetic rehabilitation and surgical reconstruction of palate defects in radiation-naïve tissues are well described. However, palatal fistulas developing after initial tumor extirpation, free-flap reconstruction, and adjuvant radiation or chemoradiation are associated with challenging secondary tissue effects. In this review, we will discuss the management of palatal fistulas after surgical reconstruction and radiotherapy.

The Role of Full-Thickness Skin Grafts in Patient’s Rehabilitation after Maxillectomy and Midface Defects

(1) Background: Nowadays, microvascular grafts are the gold standard in the reconstruction of midface defects after maxillectomy, however, not all patients may qualify for this type of surgery. The purpose of present study is to evaluate the benefits of alternative reconstruction methods such as full-thickness skin grafts for these conditions. (2) Methods: The research group consisted of 37 patients who underwent maxillectomy due to cancer of the mid-face and had full-thickness skin graft reconstruction. The study covered the period from 2011 to 2020. (3) Results: Based on the clinical examination and the subjective assessment of patients, a positive effect of the use of free skin grafts on their convalescence and rehabilitation was found. In particular, they contributed to the reduction in postoperative pain and pain associated with prosthetic stages (VAS Scale). (4) Conclusion: Full-thickness skin grafts in combination with individual prosthetic restorations are a good alternative to rehabilitation in patients who do not qualify for microsurgical treatment.

Functional and Aesthetic Lower Lip Reconstruction Using the Yotsuyanagy Flap

ABSTRACT

Lower lip defects are a major challenge from a reconstructive perspective. The lower lip is an anatomical region formed by different types of tissue, and it is essential to obtain adequate functional and aesthetic results. When local tissue is available to be a donor area, it becomes the best option to repair the defect. This article's purpose is to present our experience in reconstruction of partial or transfixing total defects of the lower lip with the musculocutaneous flap of the depressor anguli oris described by Yotsuyanagi.

Soft Palate Fistula in a Patient With Normal Palate as a Rare Complication After Septoplasty

ABSTRACT

While the formation of a palatal fistula after septoplasty has been reported previously, it is a rare occurrence, especially in a patient with a normal palate. In most of the previous reports, the palatal fistulas were located on the hard palate and associated with various underlying conditions. Here, we present a case of soft palate fistula which developed in a patient with a normal palate after septoplasty. The 20-year old woman complained of liquid regurgitation after her septoplasty procedure. A pin-point size fistula opening was observed on the soft palate. A shallow depression was identified at the junction between the hard and soft palate by a computed tomography scan done before surgery. The fistula was subsequently repaired through a palatal flap. After surgery, the defect was completely closed, and the patient had no more symptoms. In addition, we review the previously reported cases of palatal fistula after septoplasty.

Resurgence of regional flaps for head and neck reconstruction

PURPOSE OF REVIEW

The strain on healthcare resources in light of the COVID-19 pandemic has forced many head and neck surgeons to explore reconstructive options that may decrease length of stay. Here, we review three common and versatile regional flaps used in head and neck reconstruction that are comparable alternatives to free tissue transfer.

RECENT FINDINGS

Initial anatomic descriptions of the facial artery musculocutaneous (FAMM) flap, the supraclavicular artery island flap and the submental artery island flap were published decades ago. Since then, many have proposed modifications to these descriptions to improve technical ease and patient outcomes. Benefits of regional flaps include ease of harvest, comparable outcomes to free tissue microvascular flaps, shorter operative time and hospital length of stay. Drawbacks to regional flaps include limitations to size and reach, partial necrosis, wound dehiscence and surgeon experience. The integrity of the vascular pedicle is also contingent upon vessel preservation during the cancer ablation.

SUMMARY

Although a resurgence of regional flaps began well before the COVID-19 pandemic, many institutions began looking for alternatives to free flap reconstruction to conserve healthcare resources and minimize patient hospitalization time in the past year. There has been a revival of regional flaps such as the FAMM, supraclavicular and submental flaps that are valuable reconstructive options for many defects of the head and neck.

Locoregional Flap Reconstruction Following Oromaxillofacial Oncologic Surgery in Dogs and Cats: A Review and Decisional Algorithm

Primary treatment of most oromaxillofacial tumors in dogs and cats is resective surgery. Management of malignant tumors may be very challenging as wide/radical free-margin surgical removal must be achieved while preserving vital functions. Removal of orofacial tumors may result in large defects exposing the oral cavity or creating a communication with the nasal, pharyngeal, or orbital cavities. Such defects require orofacial reconstruction in order to restore respiratory and manducatory functions. The veterinary surgeon must be familiar with reconstructive techniques in order to prevent the inability of closing the defect, which could lead to an insufficient resection. Small oral defects exposing the nasal cavity are best closed with local random mucosal flaps. Closure of large oral defects may be better achieved with a facial or major palatine-based axial-pattern flap. Small to moderate facial defects can be closed with local advancement or transposition skin flaps. Reconstruction of large facial defects often requires the use of locoregional axial pattern flaps such as the caudal auricular, the superficial temporal, or the facial (angularis oris) myocutaneous axial pattern flaps. Recent publications have shown that the facial (angularis oris) flap is a very versatile and reliable flap in orofacial reconstructive surgery. A surgical decision algorithm based on the size, nature, and location of the defect is proposed.

Clinical management of squamous cell carcinoma of the tongue: patients not eligible for free flaps, a systematic review of the literature

INTRODUCTION

The management of squamous cell carcinoma (SCC) of the tongue represents the most demanding treatment planning in head and neck surgery. Ablation followed by free flap reconstruction is considered the gold standard, but not all patients are suitable for this strategy. The aim of this review is to provide a comprehensive view of surgical reconstruction possibilities in patients not eligible for free flaps.

METHODS

Following PRISMA recommendations, a systematic literature review was conducted searching for original papers that investigated outcomes of patients treated by surgical ablation for tongue SCC followed by reconstruction with local or pedicled flaps. Selected papers were read and data extracted for qualitative analysis.

RESULTS

Twenty articles met the inclusion/exclusion criteria. The study design was case series in sixteen papers, cohort study in the remaining four. Four different local flaps (BMM, FAMM, NLIF, SMIF) and four regional flaps have been discussed in included studies (IHF, SFIF, SCM, PMMC).

CONCLUSION

The improved anatomical knowledge makes local flaps a reliable alternative to free tissue transfer in cases requiring small-/medium-sized defects. Regional flaps still represent cornerstones in reconstruction of the tongue. Ease of execution, costs-to-benefit ratio, low-rate complications, minimal donor site morbidity represent the best advantages choosing local/regional flaps.

Subclavicular flap: A valid reconstructive option among anterior chest flaps in oral cancer patients

BACKGROUND

The subclavicular pedicled flap is based on the thoracic branch of the supraclavicular artery, and it represents a versatile reconstructive option for low-middle third face defects. Since its use in head and neck surgical oncology has not been popularized yet, we propose its application for oral cavity reconstruction after cancer resection by showing favorable results.

METHODS

Eighteen subclavicular pedicled flaps were used to treat intraoral defects after oral squamous-cell cancer resection between June 2015 and December 2018. Tumor dissection type, complications, donor and reconstructed area results, and functional and aesthetic outcomes were assessed.

RESULTS

No major complications were observed and all of the flaps survived. Adjuvant therapy was administered without delay when needed, and all of the patients had normal functional outcomes and good aesthetic results.

CONCLUSIONS

The subclavicular flap is an excellent choice for the reconstruction of oral cavity defects. Selection of patients should exclude positive lower-third neck node and include appropriate informed consent for women due to the possibility of deformity of the breast. In our opinion, this flap has the potential for common application given its consistent anatomy and donor site advantages, including long pedicle, high pivot point, and relatively unlimited flap width.
