Comprehensive Management of Oroantral Fistula Secondary to Chronic Maxillary Osteomyelitis: A Case Report.
Article in Cureus, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
This case report describes the successful management of a rare oroantral fistula (OAF) secondary to chronic osteomyelitis in a 50-year-old woman presenting with persistent right maxillary swelling, purulent discharge, and oroantral communication persisting for six months. The case was complicated by systemic comorbidities and increased susceptibility to infection, with no history of dental extractions or trauma. The initial misdiagnosis of nasal polyps led to an unsuccessful endoscopic sinus surgery. Cone-beam computed tomography revealed extensive osteolytic lesions and buccal bone necrosis, whereas histopathology confirmed chronic osteomyelitis with hypertrophic sinus mucosa. Surgical intervention under general anesthesia involved atraumatic extraction of the affected teeth, debridement of the necrotic bone, excision of the hypertrophic sinus lining, and closure with a buccal advancement flap. Postoperative care included antibiotics and medical optimization of comorbidities, resulting in complete symptom resolution at the one-month follow-up. This case highlights the diagnostic challenges of osteomyelitis-driven OAF and emphasizes the critical role of comprehensive imaging, histopathological confirmation, and a multidisciplinary approach that integrates surgical precision with systemic management of the disease. These successful outcomes underscore the need for tailored strategies to address complex OAFs, particularly in patients with systemic risk factors, to achieve optimal healing and prevent recurrence.
