**7. Conclusions**

Because of the anatomy of the maxillary sinus, pathological structures that develop and grow in the sinus can reach a large size without any serious complaint by the patient, making early diagnosis unlikely and treatment is important to address morbidity.

OPG and CT scans aid in the diagnosis of cysts localized in the sinus and CT scans are indispensable in surgical strategy planning. Good visualization during the operation provides a better opportunity for good cleaning of pathologies, better bleeding control, and minimal trauma. For better visualization, the use of endoscopy during the operation can simplify and enhance the procedure. Also, close observation of patients in the early postoperative period and regular follow-up in the later postoperative period are important.
