Formation of cysts associated with such three-dimensional growth of the maxillofacial skeleton as well as deciduous and permanent tooth development. The origin of cystic jaw lesions may be odontogenic or non-odontogenic, developmental, or inflammatory and they are epithelial-lined or non-epithelial-lined cysts in nature. These cysts are considered to be aggressive cysts when they tend to grow rapidly and can cause significant damage to the surrounding bone and tissues if left untreated. Aggressive cystic lesion of the jaw needs special attention in order to prevent recurrences or even worsen and widespread disease. The management of the maxillary sinus requires individualisation based on its clinical and histopathological characteristics. Here, we report a case of an aggressive odontogenic cyst in a 30s-aged female patient in the left maxillary sinus with the literature review.
