A Novel Technique for Oroantral Communication Closure
Objectives: Given the shortcomings of local buccal flaps, palatal flaps, and buccal fat pads in closure of oroantral communication OAC, we introduce a novel technique assembling advantages of PRF and surgical flaps.
Methods: A case report of an oroantral communication in patient with posterior edentulism that was created after extraction of the upper wisdom teeth and was managed with a novel technique :Rotational Crestal Flap Associated with PRF
Results: Rotational crestal flap combined with PRF combines the advantages of surgical flaps and PRF. It is a quick, simple, and secure procedure since it avoids the risk of damaging the large palatal artery observed in the palatal flap. It allows the supply of gum attached tissue to the receiving site. It also preserves the buccal sulcus depth, which allows a possible and rapid denture confection. Moreover, it reduces pain and swelling compared to other techniques (BAF and FPF), and decreases the risk of infections due to the anti- inflammatory properties of PRF. It is also important to note that the use of PFR stimulates angiogenesis and re-epithelialization, leading to a fast healing. However, this technique presents two major disadvantages. The first disadvantage is the postoperative pain in the site of the raised flap due to the uncovered bone, which could be overcome using a partially thickness flap. The second one lies in the formation of a nodule at the base of the flap due to its rotation, necessitating desepithelization.
Conclusions: Rotational crestal flap associated with PRF is a novel and reliable option for repairing small and medium-sized OAC. This technique must be considered for OAC closure in patients with posterior edentulism for whom prosthetic restoration with a removable denture is scheduled. It preserves the vestibule depth and allows a supply of attached gingiva to the receiving site.
