Closure of oroantral fistula using platelet rich fibrin with endoscopic middle meatal antrostomy

BackgroundOroantral fistula (OAF) involves pathological, epithelialized, and unnatural communication between the maxillary sinus and oral cavity. Recently, functional endoscopic sinus surgery has provided minimally invasive treatment options with fewer postoperative complications. The aim of the study was to evaluate the one-stage endoscopic middle meatal antrostomy (EMMA) technique with the application of a platelet-rich fibrin membrane (PRF) for OAF closure and maxillary sinusitis relief.Patients and methodsPatients who suffered from OAF with odontogenic sinusitis were included in this study. Complete excision of the epithelial tract and any necrotic tissue was performed with proper curettage. Then, EMMA was performed with simultaneous closure of the OAF by the application of PRF membranes that were fixed by sutures and covered with an acrylic splint. Patients were clinically evaluated for OAF closure, pain level, and symptom relief. Additionally, the size of the bone defect was measured with the aid of computed tomography (CT) preoperatively and after 24 weeks postoperatively.ResultsThis study included nine eligible patients with a mean age of 38 years. The data were collected, tabulated, and statistically analyzed. Soft tissue healing and bone formation occurred in all patients who achieved maxillary sinusitis relief without any complications. Additionally, pain was significantly lower on the 7th postoperative day than on the 1st postoperative day, according to the statistical analysis of the results (p < .001).ConclusionsOne-stage EMMA with the application of PRF membranes and acrylic splint represents a reliable alternative technique for OAF closure and maxillary sinusitis relief that is associated with a lower incidence of complications and minimal postoperative pain.Trial registrationThe trial was registered on 28/02/2024, at clinicaltrials.gov (ID: NCT06281873).

A pedicled buccal periosteal flap for the closure of oro-antral fistula

BackgroundAn oroantral fistula is a communication between the maxillary antrum and oral cavity. This pathological communication is formed mainly due to dental extraction of maxillary premolars and molars. Adequate management should include closing the oroantral fistula and eliminating sinus infections to prevent recurrence and sinusitis.PurposeThis study aimed to evaluate the effectiveness of using the pedicled buccal periosteal flap for closing an oroantral fistula without changing the native intraoral structure.Patients & MethodsPatients with oroantral fistulas were included in this study. The patients were examined clinically by Valsalva test and cheek-blowing test, the hole was probed, and the extent of the underlying bone defect was determined radiographically using computed tomography preoperatively. All patients underwent surgical closure of oroantral fistula using a pedicled buccal periosteal flap.ResultsAll 10 patients obtained satisfactory results with marked improvement in the function of the maxillary sinus and complete healing of oroantral fistula with no recurrence except in Case No. 5, who had a recurrence of the oroantral fistula, also there was no statistically significant difference between the vestibular depth preoperatively and postoperatively.ConclusionA pedicled buccal periosteal flap is a novel technique for oroantral fistula closure as it preserves vestibular depth with a tension-free closure flap and harbors the advantages of the regenerative potential of the periosteum.Registration date14/8/2023Registration numberNCT05987943

Repair of Oroantral Fistulas Using Free Bone and Mucoperiosteal Flaps After Endoscopic Removal of the Medial Wall of the Maxillary Sinus.

Oroantral fistula (OAF) refers to a pathological connection between the oral cavity and maxillary sinus. It may lead to symptoms that include purulent mucus, nasal congestion, facial swelling, bad breath, and nasal regurgitation of food, all of which negatively impact patients' quality of life. This study presents a novel approach for OAF repair using a 2-layered structure composed of free bone and a mucoperiosteal flap obtained from the medial wall of maxillary sinus. Ten OAF patients who underwent repair using this method were retrospectively reviewed between August 2015 and June 2022. The extraction of maxillary molars was the most common cause of OAF. The size of the fistulas ranged from 1×2mm to 5×8mm. Nine of the 10 patients achieved successful OAF closure following the initial operation using the 2-layer structure composed of free bone and mucoperiosteal flag. One patient was lost to follow-up. The 9 patients were observed for 6 months to 1 year, and they exhibited no obvious complications or recurrence. The use of free bone and mucoperiosteal flag from the medial wall of maxillary sinus through an endoscope was effective for OAF repair.

Application of double layer with collagen-elastin matrix (Matriderm®) and polyglycolic acid sheet (Neoveil®) for oroantral and oronasal fistula closure after maxillectomy: a retrospective single center experience

PurposeThis study investigates the effectiveness of a new double-layer approach for closing oroantral and oronasal fistulas (OA/ONFs) using Matriderm® and Neoveil®. Matriderm®, an acellular dermal matrix composed of collagen and elastin fibers, supports tissue regeneration, while Neoveil®, a biodegradable mesh sheet, serves as a barrier to prevent leakage and scarring. Material and MethodsA retrospective study of 12 maxillectomy patients with oral cancer between January 2022 and May 2023 was conducted. Patient data, including tumor stage, bone invasion, and defect size, were analyzed. Surgical techniques included sinus mucosa preservation, and either buccal fat grafting combined with the double layer technique or the double layer technique alone, with statistical analysis performed using R software to evaluate outcomes. ResultsThe results indicate a 41.7% incidence rate of fistula formation with lower T stages, absence of bone invasion, smaller defect dimensions, and intact sinus mucosa correlating with reduced fistula risk (p < 0.05). Notably, no patients required fistula-related surgical revisions, validating the efficacy of the approach. ConclusionThis study introduced a novel double-layer technique using Matriderm® and Neoveil® for closing OA/ONFs after maxillectomy. The technique demonstrated promising outcomes in addressing these post-operative complications. Lower tumor stages, no bone invasion, smaller defects, and intact sinus mucosa correlated with reduced fistula risk. This technique holds potential to enhance maxillectomy outcomes, offering a comprehensive approach to functional concerns, but warrants further investigation.

Anatomical and Surgical Implications of the Usage of Bichat Fat Pad in Oroantral Communication, Maxillary, Palatal, and Related Surgeries-Narrative Review.

The buccal fat pad, also called the Bichat's fat pad (BFP), is an encapsulated fat mass located in the cheek. This type of specialized fat mass can be used both as a pedicular or free graft in various surgeries and approaches. Due to its easy access from the oral cavity approach, it is commonly used for oroantral and palatal fistula closure. The knowledge of its anatomy and surrounding tissues plays a role in its mobilization and suturing onto the desired defect in the palatal or maxillary region. The BFP is mostly associated with the primary approach used for a fistula or bone surgery. Alternatively, the procedure can be performed with a single approach incision, which does not compromise the appearance or the function of the operating or adjacent areas. The most important inclusion criteria for BFP usage and surgical limitations are highlighted. The BFP is used for multiple purposes in reconstructive and oncology surgery and also has its use in esthetic and facial contouring procedures. The amount, volume, and shape of the BFP are mostly associated with the scope of their usage. The aim of the following narrative review is to present the surgical and anatomical implications of fat pads in maxillary and palatal surgeries.

The double-barrier technique using platelet-rich fibrin for closure of oroantral fistulas.

An oroantral fistula (OAF) or oroantral communication (OAC) is an opening between the oral cavity and the maxillary sinus. If left untreated, these openings may cause chronic maxillary sinusitis. Although small defects (diameter <5 mm) may close spontaneously, larger communications require surgical intervention. Various studies have been conducted on OAC closure using a platelet-rich fibrin (PRF) membrane; most of these prior studies have involved simple direct application of PRF clots. This study introduces a new "double-barrier technique" using PRF for closure of an OAF involving sinus mucosal lifting and closure. The PRF material is inserted into the prepared maxillary sinus space, and the buccal advancement flap covers the oral side. This technique was successfully used to treat two patients with chronic OAF in the posterior maxillary region after implant removal or tooth extraction. The use of a PRF membrane in a double-barrier technique may have advantages in soft-tissue healing and could enable easy closure of chronic OAF with minimal trauma.

A Study of Two Novel Techniques for One-stage Closure of Chronic Oroantral Fistula and Sinus Floor Lift.

This study aimed to compare two novel techniques for chronic oroantral fistula (OAF) closure combined with maxillary sinus floor elevation. Ten patients who had implant installation needs but suffered from a chronic OAF were enrolled in the study from January 2016 to June 2021. The technique applied involved OAF closure and simultaneous sinus floor elevation by either a transalveolar or lateral window approach. Bone graft material evaluation results, postoperative clinical symptoms and complications were compared between the two groups. Student's t -test and χ 2 test were used to analyze the results. In this study, 5 patients with a chronic OAF were treated with the transalveolar approach (group I), and 5 were treated with the lateral window approach (group II). The alveolar bone height was significantly higher in group II than in group I ( P ＜0.001). The pain at 1 day ( P =0.018) and 3 days ( P =0.029) postoperatively and facial swelling at 7 days ( P =0.016) postoperatively were obviously greater in group II than in group I. There were no severe complications in either group. The techniques combined OAF closure with sinus lifting to reduce surgical frequency and risks. The transalveolar approach resulted in milder postoperative reactions, but the lateral approach could provide more bone volume.

Infected Dentigerous Cyst of Maxillary Sinus Mimicking Intraoral Abscess in a Pediatric Patient: Management of Misdiagnosis and Inaccurate Treatment

The article presents the case of a 12-year-old male patient who was suffering from exacerbated (infected) dentigerous cyst of maxillary sinus, associated with impacted canine whose symptoms were deceptively similar to intraoral abscess. The first-aid treatment performed by general dental practitioner consisted of intraoral incision and resulted in oroantral fistula formation. Eventually, the patient's ailments were not resolved, and we had to deal with serious local complications and difficulties. The treatment was performed under general anesthesia in one-day surgery system and included enucleation of the lesion, excision, and closure of oroantral fistula. Dislocated canine was not removed, and its subsequent eruption was observed.

THE EFFECTIVENESS OF THE TWO-LAYERED CLOSURE OF PERSISTENT OROANTRAL FISTULA USING BUCCAL FAT PAD AND BUCCAL ADVANCEMENT FLAP.

Background: A prospective clinical study was conducted to assess the effectiveness of the two -layered closure of recurrent Oroantral Fistula using Buccal Fat Pad and Buccal Advancement Flap. Materials and methods: Twenty patients with persistent OAFs larger than 5 mm were treated with two layered closure using Buccal Fat Pad and Buccal Advancement Flap.They were followed clinically and radiographically for 5 years after surgery to monitor the durability and effectiveness of the two layered closure of the OAF. Result: The procedure was successful in all patients. The healing process was satisfactory,with no breakdown or liquefaction necrosis postoperatively.No complications were observed during the follow-up period. Conclusion: The results of this study support the view that the use of the double-layered closure using BFP with buccal advancement flap is a durable,convenient,and effective method for the treatment of a persistent large OAF.

1662 Closure of Oro-Antral Fistulae in Conjunction with Functional Endoscopic Sinus Surgery: A Retrospective Analysis + Systematic Review

Abstract Aim The aim of this study was to evaluate the surgical closure of OAFs created following dental extractions in conjunction with FESS in adult patients within a hospital in South Wales, UK, during a 5-year period, from 1st January 2014 to 31st December 2018, with a systematic review of the literature to investigate success rates. Method A manual search in the hospital’s theatre system for surgery between 2014 and 2018 containing codes for FESS, OAC or OAF was completed. These were screened for joint cases, and the patient’s hospital numbers entered into a Microsoft Excel spreadsheet. A retrospective analysis of their clinical records was performed. Success was measured as total closure and relief of sinusitis after 1 month. The PRISMA format was used to complete the systematic review. Results 13 patients (mean age 51 ± 12.44, 7:6 male to female) met the inclusion criteria. The most common cause was extraction of the maxillary first molar. A 100% success rate was achieved, with no patients requiring revision surgery. The systematic review highlighted an average success rate of 98.7%. A protocol for the management of OACs was designed in both English and Welsh and distributed to Primary Care Dentists within South Wales. Conclusions OAF closure with FESS can be considered as a highly effective approach, leaving patients symptom free. It is important that protocols are in place for dentists suspecting an OAC in order to expedite patient management.

BACKGROUND The maxillofacial region has several congenital and acquired defects. Because of its abundant blood supply and proximity to different intraoral abnormalities, the buccal fat pad flap (BFP) is a simple and reliable flap that can be used to repair a variety of these abnormalities. BFP has remarkable qualities as a scaffold and autogenous dressing in the healing of intraoral defects after excision of oral cavity intraoral lesions. Filling and allowing slippage of fascial spaces between muscles of facial expression, advancement of intermuscular motion, isolating mastication muscles from one another, counteracting negative pressure during suction in the newborn, protection and cushioning of neurovascular bundles from injuries are among the functions of BFP. It also has a dense venous network that facilitates exoendocranial blood flow via the pterygoid plexus. For many years, the BFP was considered a surgical annoyance due to its incidental encounter during various surgeries in the pterygomaxillary space or following injuries to the craniofacial region. However, various clinical applications of BFP have been introduced in recent years. We looked at BFP and its anatomical foundation, surgical procedures, and clinical applications in this review article. The surgical method is easy and effective in a wide range of clinical situations, including oroantral fistula closure, congenital defect rectification, Osteoradionecrosis treatment, and reconstruction of tumor or cyst defect. Thus BFP is a dependable flap that may be used in a variety of therapeutic conditions. KEY WORDS Buccal Fat Pad Flap; Oral Mucosa; Reconstruction; Defect.

Role of Endoscopic Sinus Surgery and Dental Treatment in the Management of Odontogenic Sinusitis Due to Endodontic Disease and Oroantral Fistula.

Background: Odontogenic sinusitis (ODS) is frequently encountered in ENT practice; however, there are no guidelines regarding its management. This study aims to analyse the results of endoscopic sinus surgery versus dental treatment in ODS. Additionally, we aim to demonstrate the benefit of associating endoscopic sinus surgery (ESS) to surgical closure of chronic oroantral fistulas (OAF) by comparing mean time to healing in patients who opted or not for concurrent ESS. Methods: Records of patients with ODS were reviewed. Group one consisted of patients with ODS caused by periapical pathology undergoing either endoscopic sinus surgery (ESS) or dental treatment. Resolution of ODS was considered treatment success and was compared between the two treatment strategies. Group two included patients with ODS and associated chronic oroantral communication. Time to healing was compared between patients undergoing OAF closure alone versus patients receiving associated ESS, using the Log-Rank test to correlate Kaplan–Meier curves. Results: 25 patients from a total of 45 in group one underwent dental treatment alone, and 20 opted for exclusive ESS treatment. The failure rate was 40% for patients treated with ESS compared to 4% (one patient) for dental treatment. ODS resolved in all patients in the second group, but the mean time to healing was half (10 days) when ESS was complementary to OAF closure. Conclusion: The present study represents the first estimator of the role ESS plays in OAF treatment. Nonetheless, it provides proof of the importance of first addressing dental problems in odontogenic sinusitis.

Odontogenic Maxillary Sinusitis: Therapeutic Management of Cases with Oroantral Fistulae

Odontogenic maxillary sinusitis (OMS) is a disease in which inflammation from the teeth extend into the maxillary sinus, causing symptoms of unilateral sinusitis. OMS can recur, with some being resistant to antibiotics. In intractable cases, exodontia and endoscopic sinus surgery (ESS) are necessary treatments. Here we report our analysis on the indications for surgical intervention in cases diagnosed with and treated as OMS. We retrospectively examined 186 patients who were diagnosed with sinusitis on a computed tomography (CT) scan. For cases diagnosed with OMS, the site of the causative tooth and the presence or absence of oroantral fistula to the maxillary sinus was examined. In addition, we analyzed the therapeutic efficacy of the initial treatment of antibiotics, and what the indications were for ESS. Among the patients examined, OMS was diagnosed in 44 cases (23.6%). In 14 out of 20 cases that underwent a post-medical treatment CT scan, OMS found to be treatment-resistant. Of these 14 cases, 12 (88%) had oroantral fistulae to the maxillary sinus. In all cases where exodontia, fistula closure surgery, and endoscopic sinus surgery (ESS) were performed, the fistula disappeared and the shadow of inflammation in the paranasal sinus improved. In OMS with oroantral fistula, ESS, exodontia, and fistula closure should be recommended over medication such as macrolide therapy.
