“…The oroantral communication (OAC) is the connection between the maxillary sinus and the oral cavity. If left untreated, it might lead to oroantral fistula or maxillary sinusitis (20). Oroantral communication normally occurs when the maxillary molar teeth are removed.…”

INTRODUCTION:After posterior maxillary teeth extraction, oroantral communication is a reasonably common significant consequence. At the time of injury, if the opening is > 4-5 mm, surgical closure of the antral perforation is required. This study aimed to check the value of BioXclude amnion chorion membrane in repairing oroantral communication. MATERIALS AND METHODS:Ten patients with oroantral communication that occurred after posterior maxillary teeth extraction were included in the study. Surgery was considered successful in case of negative nose blowing 1-month postoperatively. Post-operative pain was assessed. Evaluation of bone formation at the communication site by computed tomography was measured post operatively at 3 and 6 months. RESULTS: After 3 and 6 months, all patients (100.0%) showed bone formation, and a significant increase in bone density was noted. After 6 months there was a significant closure of OAC. CONCLUSION: Amnion chorion membrane is an excellent scaffold layer for covering iatrogenic oroantral communication defect. BioXclude has self-adhering properties once it becomes moist. This eliminates the need for suturing of the membrane.

“…Therefore, the first goal is to treat any coexisting maxillary sinus infection. Likewise, the defect in the present case was closed by surgical intervention following conservative treatment using a combination of oral antibiotics, topical nasal steroids, and hypertonic antral irrigation [ 11 , 12 ].…”

Oroantral communication is an unnatural communication of the maxillary sinus with the oral cavity, often resulting from dental extractions, infection, trauma, or excision of cysts or tumors. Pathological epithelialization of oroantral communication leads to oroantral fistula. Various techniques have been proposed for surgical closure. Uneventful healing of the defect can be achieved in the absence of antral infection. Hence, medical management of maxillary sinusitis should precede surgical closure of the defect. Here, we report a case of an oroantral fistula of the left maxillary third molar, caused by a secondary infection of the extraction site, managed primarily by antibiotics, topical steroids, and irrigating agents followed by surgical closure. It is essential to carefully inspect the post-extraction socket of maxillary teeth due to its high risk of development of oroantral communication. Also, the management of oroantral communications needs early detection to prevent infection and to prevent transforming into an oroantral fistula. In case of an infected oroantral communication or fistula, priority rests on treating the infection first and followed by surgical repair.

“…The clinical diagnosis of OAC/OAF is usually based on subjective and objective findings, patients may be asymptomatic [11] , but most complain of symptoms that may be acute or chronic. Acute symptoms include epistaxis, passage of fluid or air through the OAC/OAF, pain in and around the affected sinus area, voice alteration, and wheezing when speaking [2] . Chronic symptoms include alleviated pain, free drainage of fluids through the oral fistula, mucopurulent nasal discharge, antral polyps may be visualized through the defect at a later stage, postnasal drip, bad intraoral odor and taste, voice alterations and earache [9] , [11] .…”

“…To validate the clinical findings, radiological investigation of the OAC and OAF site is necessary [2] , [11] , [13] , [14] . A panoramic radiograph and a blond CT scan can determine the size, location, and degree of sinus involvement [13] .…”

“…The proximity of the maxillary sinus during extraction of antral teeth, most often the upper molars and premolars, is the main reason for this complication (48 %). Interventions on cystic or tumoral pathologies (18.5 %), or following a trauma (7.5 %) can lead to the creation of an oral-sinus communication [2] . Other causes include osteoradionecrosis, infection, sinusitis, osteomyelitis, during implant surgery or following dehiscence after implant failure and sometimes as a complication of the Caldwell-Luc procedure [1] , [3] .…”
