Introduction: Oroantral communication is an uncommon, inadvertent incident resulting from various causes the most common
of which is the extraction of upper molars. Immediate closure of the communication is highly recommended to avoid infection
and subsequent fistulous tract formation. Cyanoacrylate tissue glue was introduced as a reliable method for flapless sealing of the
communication without any of the complications associated with the surgical maneuvers. One of the oldest surgical procedures
used for closure of the Oroantral communication is the buccal advancement flap which proved efficiency in complete closure
of the defect with minimal related complications.
Aim of the study: The study aims evaluate the immediate flapless closure of Oroantral communication using cyanoacrylates
versus the buccal sliding advancement flap.
Patients and Methods: Twenty patients suffering from instant oroantral communication were included in the study. CBCT
was performed to each of them to confirm the diagnosis, patients were divided into two groups where Group I (Study group)
patients were treated by sealing of the defect using periacry l90 HV while Group II (control group) patients performed Buccal
sliding advancement flap. Clinical follow up including pain, facial swelling, recurrence of the defect and sulcular depth up were
performed at day 1, 3, 7, 15 and 1 month. CBCTs were done at 3 and 6 months postoperative to assess healing of the defect
regarding size and density.
Results: Clinically Group I showed minimal pain and swelling with no change of sulcular depth. In contrast, Group II showed
high pain level and increase in facial swelling together with a significant decrease in sulcular depth. None of the patients in
both groups showed any recurrence of the condition. CBCTs showed decrease in defect size and formation of bone within the
defect in both groups.
Conclusion: Both maneuvers are good modalities for treating OAC, however cyanoacrylate is associated with minimal
