Closure of chronic oroantral fistula: Comparison between pedicled buccal pad fat flap and free buccal pad fat graft.

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
Background and Objective: Oroantral communication and fistula are not uncommon complications of maxillary molar extraction. The objective of this study was to evaluate the efficacy of buccal fat flaps and grafts in the closure of oroantral fistulae. Materials and Methods: This prospective comparative clinical study involved patients with chronic oroantral fistulae. In 13 patients, a pedicled buccal fat pad flap was used for closure (group 1), while a free buccal fat graft was used in 14 patients (group 2). Parameters assessed included the duration of surgery, extent of facial swelling, loss of vestibular depth, and wound breakdown and failure of closure. Results: The mean duration of surgery was 32.4 (10.5) minutes in group 1 and 29.8 (8.6) minutes in group 2. The amount of facial swelling on the second postoperative day was 2.5 (±0.6) cm in group 1 and 1.3 (±0.8) cm in group 2. At two weeks postoperatively, the reduction in vestibular depth was 5.2 (±1.7) mm in group 1 and 3.7 (±0.9) mm in group 2. Significantly greater facial swelling and reduction in vestibular depth were observed in group 1 compared to group 2 ( Conclusion: When employed as a free graft or pedicled flap, the buccal fat pad has demonstrated success in closing oroantral fistulas, even when dealing with large defects. This technique can be utilized either independently or in conjunction with a buccal vestibular flap to achieve a double-layer closure, enhancing the effectiveness of the procedure.
