Unilateral maxillary sinus aplasia is one of the rare anomalies of maxillary sinus. Few cases have been reported. Ipsilateral rhinolith with unilateral maxillary sinus aplasia is also a very rare association and no case has been documented till date. We report a case of a 21-year-old female with left maxillary sinus aplasia and ipsilateral rhinolith. Rest of the sinuses being normal.

introduction: a hydatid cyst of the head and neck is a very rare condition, even in areas where echinococcus infestation is endemic.   case report: we report a rare case of primary hydatid cyst of the right maxillary sinus in a 40-year-old man. the initial diagnosis of the presence of a cystic mass was the result of physical examination and computed tomography (ct) scan. we resected the cystic ...

introduction calcifying odontogenic cyst (coc) is an uncommon odontogenic lesion, classified in two variants: the cystic variant and neoplastic (solid) variant. case presentation this case report presents multiple coc, which involved the maxillary bone and sinus in a 30-year-old man. several of these lesions were cystic, while the others were neoplastic in type, and the lesions were removed sur...

introduction: comparison of the relationships and distance between maxillary root tips and   the maxillary sinus floor using oral panoramic in the dolichocephalic and brachycephalic compared to mesocephalic individuals. methods: oral panoramic images from 300 individuals were analyzed and the relationships and distance between the maxillary root tips and the sinus floor was assessed by qualitat...

calcifying epithelial odontogenic tumor (ceot) is an uncommon odontogenic tumor with well-known histopathological features and a challenging treatment plan. although some investigators advocate conservative approach as the treatment of choice, others believe in radical surgical excision to avoid recurrence or malignant transformation. the main objective of this case report is presenting an unus...

calcifying epithelial odontogenic tumor is a rare odontogenic neoplasm. its occurrence in the maxillary sinus is very rare. maxillary tumors tend to be locally aggressive and may rapidly involve the surrounding vital structures.  we report a case of calcifying epithelial odontogenic tumor involving maxillary sinus in a 48 years old female patient with the oral mucosal involvement. the purpose o...

introduction: ameloblastic fibro-odontoma is a rare, benign, asymptomatic tumor. the term ameloblastic fibro-odontoma was first used by hooker in 1967 as a separate lesion from ameloblastic odontoma.   case report: this case report describes an eleven years old female with large ameloblastic fibro-odontoma in the right maxillary sinus.   conclusion: there is a low potential for recurrence after...

Background: The thickness of maxillary sinus floor may reduce markedly because of protrusion of root apices of posterior teeth into the sinus. The possibility of oro-antral communication after extraction is highest for a maxillary first molar, as this tooth erupts first and is frequently extracted early. Aim: To assess the relationships between the roots of the maxillary first molar and the max...

OBJECTIVES The purpose of the present study was to explore the maxillary sinus anatomy, its variations and volume in patients with a need for maxillary implant placement. MATERIAL AND METHODS Maxillary sinus data of 101 consecutive patients who underwent spiral computed tomography (CT) scans for preoperative implant planning in the maxilla at the Department of Periodontology, University Hospi...
