Abstract
Oroantral communication (OAC) is one of the main complications of extracting antral or sinus teeth. OAC is a gap between the maxillary sinus and the oral cavity. When left untreated, it causes maxillary sinusitis and dramatically impairs the patient's quality of life. Numerous surgical treatment techniques have been described, from mucosal techniques to using bone substitutes or very conservative alternative means. Many cases of recurrence after treatment have been reported, and the choice of the method adapted to the clinical situation remains challenging. Therefore, it is necessary to establish a correct diagnosis and choose the surgical technique best adapted to the case. This work is aimed at reviewing several techniques for the treatment of OAC and at describing our recommendations for use in daily practice for each of them through four clinical cases.

OACs can be induced by tumor surgery, implant surgery, trauma, or orthognathic surgery involving the maxilla
Summary
Oroantral communication (OAC) is a gap between the maxillary sinus and the oral cavity. It can lead to an oroantral fistula and maxillary sinusitis [1]. Oroantral communications are often iatrogenic following the extraction of antral or sinus teeth. In the face of extensive untreated oroantral communication, 50% of patients develop sinusitis after 48 hours and 90% after two weeks with a filling of the sinus on radiological examination [3] (Figure 2). OACs less than 5 mm close spontaneously [4]. This work is aimed at describing the different therapeutic options of OACs through some clinical cases and at presenting the decision factors of these treatments
