underdiagnosed due to its nonspecific clinical presentation, which overlaps with other types of rhinosinusitis. The etiopathogenesis involves a complex interplay of factors including iatrogenic causes, periodontal infections, and traumatic events, leading to a persistent inflammatory response in the maxillary sinus. This report details a clinical case involving a 19-year-old male patient presenting with exacerbated sinusitis symptoms linked to a carious upper right first molar. Clinical manifestations included blurred vision, facial pain, and nasal regurgitation of liquids. Radiographic analysis revealed a radiolucent area indicative of sinus involvement, confirming the diagnosis of OMS.Surgical intervention comprised the extraction of the infected molar and the debridement of the maxillary sinus, followed by the application of Bichat’s fat pad to repair the resulting oroantral communication. This technique demonstrated effective closure of the defect, promoting tissue healing and reducing postoperative complications. The postoperative regimen included antibiotics, anti-inflammatories, and antihistamines, which facilitated recovery. This case underscores the necessity of a multidisciplinary approach in the diagnosis and management of OMS, integrating dental and surgical expertise to optimize patient outcomes. Imaging plays a crucial role in the diagnostic process, enabling precise identification of odontogenic lesions and their extent. The successful use of Bichat’s fat pad highlights its utility in oral-maxillofacial surgery for managing oroantral fistulas. This report contributes to the growing body of evidence supporting the importance of tailored surgical and medical strategies in managing complex cases of odontogenic maxillary sinusitis.
