Recent trends and perspectives in reconstruction and regeneration of intra/extra-oral wounds using tissue-engineered oral mucosa equivalents. JAPANESE DENTAL SCIENCE REVIEW 2023; 59:365-374. [PMID: 37954029 PMCID: PMC10632115 DOI: 10.1016/j.jdsr.2023.10.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/25/2023] [Revised: 09/25/2023] [Accepted: 10/19/2023] [Indexed: 11/14/2023] Open
Abstract
Many conditions, including cancer, trauma, and congenital anomalies, can damage the oral mucosa. Multiple cultures of oral mucosal cells have been used for biocompatibility tests and oral biology studies. In recent decades, the clinical translation of tissue-engineered products has progressed significantly in developing tangible therapies and inspiring advancements in medical science. However, the reconstruction of an intraoral mucosa defect remains a significant challenge. Despite the drawbacks of donor-site morbidity and limited tissue supply, the use of autologous oral mucosa remains the gold standard for oral mucosa reconstruction and repair. Tissue engineering offers a promising solution for repairing and reconstructing oral mucosa tissues. Cell- and scaffold-based tissue engineering approaches have been employed to treat various soft tissue defects, suggesting the potential clinical use of tissue-engineered oral mucosa (TEOMs). In this review, we first cover the recent trends in the reconstruction and regeneration of extra-/intra-oral wounds using TEOMs. Next, we describe the current status and challenges of TEOMs. Finally, future strategic approaches and potential technologies to support the advancement of TEOMs for clinical use are discussed.

Abstract
Significance: Orofacial structures are indispensable for speech and eating, and impairment disrupts whole-body health through malnutrition and poor quality of life. However, due to the unique and highly specialized cell populations, tissue architecture, and healing microenvironments, regeneration in this region is challenging and inadequately addressed to date. Recent Advances: With increasing understanding of the nuanced physiology and cellular responses of orofacial soft tissue, novel scaffolds, seeded cells, and bioactive molecules were developed in the past 5 years to specifically target orofacial soft tissue regeneration, particularly for tissues primarily found within the orofacial region such as oral mucosa, taste buds, salivary glands, and masseter muscles. Critical Issues: Due to the tightly packed and complex anatomy, orofacial soft tissue injury commonly implicates multiple tissue types, and thus functional unit reconstruction in the orofacial region is more important than single tissue regeneration. Future Directions: This article reviews the up-to-date knowledge in this highly translational topic, which provides insights into novel biologically inspired and engineered strategies for regenerating orofacial component tissues and functional units.

Factors affecting polyglycolic acid sheet engraftment success for covering mucosal defects from head and neck surgery. Jpn J Clin Oncol 2023:7136608. [PMID: 37093674 DOI: 10.1093/jjco/hyad035] [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: 12/22/2022] [Accepted: 04/05/2023] [Indexed: 04/25/2023] Open
Abstract
BACKGROUND Polyglycolic acid (PGA) sheets have been used with fibrin glue to cover extensive mucosal defects in oral and pharyngeal surgery; however, the sheets can fall off before wound healing is completed. Hence, prolonged fasting is often recommended in such patients. However, there are few studies on the factors that shape PGA sheet engraftment. We studied sheet engraftment rates considering these factors. METHODS All consecutive cases of oral surgery in 2013-21 in which the defect was covered with fibrin glue and Neoveil® or Neoveil Nano® PGA sheets were identified. The loss of all sheets was defined as an engraftment failure. Multiple logistic regression analysis was conducted to identify whether the PGA-sheet type, application site, defect size and postoperative fasting duration predicted engraftment. RESULTS Overall, 137 patients were identified (mean age, 73 years; 57% male). The surgeries were conducted with Neoveil® in 66% of the patients; the most common site was the buccal mucosa (25%), and the mean defect size and fasting duration were 709 mm2 and 4 days, respectively. The engraftment rate was 76%. Neoveil Nano® PGA sheets were associated with a 2.8-fold better engraftment rate than Neoveil® (univariate: 87 vs. 70%, P = 0.032; multivariate: 95% confidence intervals = 1.067-7.410, P = 0.036). Other variables, including fasting duration, were not predictive of engraftment. CONCLUSIONS This is the largest case series of patients with head and neck cancer who underwent fibrin glue-PGA sheet defect coverage. The fasting duration did not influence engraftment. Therefore, early oral intake is not contraindicated in such patients.

Abstract
Here we describe a rare case of mandibular cancer involving almost the entire attached gingiva in a 71-year-old man. First, marginal resection of the entire mandible was performed, followed by one-stage reconstruction comprising application of a split-thickness skin graft onto the wound. This resulted in good alveolar ridge morphology, allowing for a mandibular prosthesis to be installed soon postoperatively. Histopathological analysis revealed a well-differentiated squamous cell carcinoma extending throughout most of the resected attached gingiva, but no malignant features in the stumps. Furthermore, no infiltration into the jawbone was observed, and no vascular or lymphatic invasion or perineural infiltration. At 3 years postoperatively, the patient's clinical course has remained uneventful, with no recurrence or problems arising in the remaining mandible. The patient is also able to eat regularly using the mandibular prosthesis provided.

Abstract
BACKGROUND AND AIMS Endoscopic resection of extensive esophageal lesions has become more common as endoscopic resection techniques and equipment have developed. However, extensive esophageal endoscopic resections can cause postoperative esophageal strictures, which have a negative impact on the quality of life of patients. We aimed to review current treatments and innovative approaches to prevent esophageal strictures after widespread endoscopic resection of esophageal lesions. METHODS We performed a comprehensive literature search from 2000 to 2016 using predetermined search terms to identify relevant articles and summarized their results as a narrative review. RESULTS A total of 21 original articles and case series were identified. A circumferential mucosal defect involving more than three fourths of the esophageal luminal circumference was the primary risk factor for developing an esophageal stricture after endoscopic resection. Oral and injectable steroid therapy demonstrated promise in preventing post-endoscopic submucosal dissection esophageal strictures, with both strategies significantly reducing the number of required endoscopic balloon dilations. More data are needed on prophylactic self-expandable metal stents, local botulinum toxin injection, and oral tranilast as a strategy to prevent post-endoscopic submucosal dissection esophageal strictures. Although preliminary studies of tissue-shielding resection sites with polyglycolic acid sheets and fibrin glue and autologous cell sheet transplantation have demonstrated promising results, additional larger validation studies are needed. CONCLUSIONS Oral and locally injected/administered steroids are first-line options for the prevention of esophageal strictures, but additional innovative solutions are being developed.

Abstract
Purpose: This study aimed to evaluate the coverage of oral wounds using either a polyglycolic acid (PGA) sheet or split-thickness skin grafting (STSG). Materials and Methods: A total of 119 cases of wound coverage using a PGA sheet and fibrin glue spray as well as 132 cases of wound coverage cases using STSG were reviewed retrospectively. The site of the excision area, perioperative conditions, and postoperative functional problems were evaluated. Results: The PGA group had significantly shorter operation time, earlier start of oral intake, and shorter hospitalization than the STSG group. If the PGA sheet over the wound with exposed bone could be protected by a surgical sprint, oral food intake could be started on the day after surgery at the earliest. When the size of the wound in the buccal excisional area was classified into two groups (<6 or ≥6 cm2), mouth opening in the STSG group was significantly larger at 3 months postoperatively. When the size of the wound in the tongue and floor of mouth was classified into two groups (<12 or ≥12 cm2), the STSG group had a significantly higher score in postoperative speech intelligibility. Conclusion: Selection of a PGA sheet or STSG based on the consideration of defect size, tumor location, patients’ local and general condition and tolerance for surgery could reduce the patients’ postsurgical dysfunctional problems.

Abstract
Gastrointestinal (GI) leakage, fistulae, and perforations can be serious and life threatening. There has been a paradigm shift in the management approach of these conditions, from surgical to conservative, including endoscopic management. Here, we report two cases of endoscopic closure of a GI fistula and perforation using polyglycolic acid (PGA) sheets with fibrin glue. The first case is of an anastomotic leak detected after subtotal gastrectomy with gastroduodenostomy. After failed application of endoclips, a PGA sheet was applied, and the fistula was successfully closed. The second case was of a 15-mm large perforated gastric ulcer, which was also successfully closed with a PGA sheet. This is the first case report that PGA sheet was used for the treatment of overt perforation. The outcome of these cases suggest that endoscopic closure using PGA sheets can be considered as a useful alternative for the management of GI leakage, fistulae, and perforations.

Abstract
Advances in diagnostic modalities and improvement in surveillance programs for Barrett esophagus has resulted in an increase in the incidence of superficial esophageal cancers (SECs). SEC, due to their limited metastatic potential, are amenable to non-invasive treatment modalities. Endoscopic ultrasound, endoscopic mucosal resection, and endoscopic submucosal dissection (ESD) are some of the new modalities that gastroenterologists have used over the last decade to diagnose and treat SEC. However, esophageal stricture (ES) is a very common complication and a major cause of morbidity post-ESD. In the past few years, there has been a tremendous effort to reduce the incidence of ES among patients undergoing ESD. Steroids have shown the most consistent results over time with minimal complications although the preferred mode of delivery is debatable, with both systemic and local therapy having pros and cons for specific subgroups of patients. Newer modalities such as esophageal stents, autologous cell sheet transplantation, polyglycolic acid, and tranilast have shown promising results but the depth of experience with these methods is still limited. We have summarized case reports, prospective single center studies, and randomized controlled trials describing the various methods intended to reduce the incidence of ES after ESD. Indications, techniques, outcomes, limitations, and reported complications are discussed.

Abstract
PURPOSE Previous studies have described the use of a combination of polyglycolic acid (PGA) sheets (a resorbable biomaterial) and fibrin glue spray to treat open soft tissue wounds during oral surgery, which have produced good results. However, there have not been any detailed investigations of the use of these materials to treat exposed hard tissue wounds. This study investigated the combination of PGA sheets and fibrin glue spray to treat exposed bone surfaces during oral surgery. MATERIALS AND METHODS PGA sheets and fibrin glue spray were applied to exposed bone surfaces after lesion resection in 8 patients (10 sites) who had been diagnosed with malignant tumors. The sheets were cut into pieces (width, 5 to 10 mm) and applied to the exposed bone surface. RESULTS PGA adhesion was confirmed for the final time on postoperative days 28 to 56 (mean, 35.8 days), and there were no cases in which the PGA sheets fell off the wound prematurely. Epithelialization of the wound surface occurred gradually and was complete by postoperative weeks 4 to 5, regardless of the size of the wound. CONCLUSION This method was considered very effective at preventing postoperative bleeding, alleviating postoperative pain, and promoting epithelialization during the reconstruction of bone surfaces after tumor resection in the oral cavity.

Abstract
Background. Fibrin sealant became the first modern era material approved as a hemostat in the United States in 1998. It is the only agent presently approved as a hemostat, sealant, and adhesive by the Food and Drug Administration (FDA). The product is now supplied as patches in addition to the original liquid formulations. Both laboratory and clinical uses of fibrin sealant continue to grow. The new literature on this material also continues to proliferate rapidly (approximately 200 papers/year). Methods. An overview of current fibrin sealant products and their approved uses and a comprehensive PubMed based review of the recent literature (February 2012, through March 2013) on the laboratory and clinical use of fibrin sealant are provided. Product information is organized into sections based on a classification system for commercially available materials. Publications are presented in sections based on both laboratory research and clinical topics are listed in order of decreasing frequency. Results. Fibrin sealant remains useful hemostat, sealant, and adhesive. New formulations and applications continue to be developed. Conclusions. This agent remains clinically important with the recent introduction of new commercially available products. Fibrin sealant has multiple new uses that should result in further improvements in patient care.
