OBJECTIVES The aim of this study is to determine the incidence, location, and orientation of maxillary sinus septa in formalin embalmed cadavers. MATERIALS AND METHODS The study was conducted on 210 cadaveric heads available in our department. After taking the mid-sagittal section the specimens were opened from the medial aspect and the sinus cavity was explored for the presence of maxillary ...

Background and Aim: Understanding the vascular anatomy of the maxillary sinus plays an important role in the success of sinus grafting and determining the location of lateral osteotomy. The aim of the present study was to localize the posterior superior al-veolar artery (PSAA) and to measure the distance from this vascular canal to the maxil-lary sinus floor and alveolar crest by cone-beam comp...

introduction: the horizontal bony canal in the lateral maxillary wall is the site of anastomosis between the arterial branches from the posterior superior alveolar artery (psaa) and the infraorbital artery. this anatomic structure is known as the ‘alveolar antral artery’.   materials and methods: we performed a literature review. the anatomic location of the alveolar antral artery in the latera...

Volume Objective: To study the size of the maxillary sinus which includes linear and volume measurements. Methods: Three dimensional computed tomography (3D CT) images of 144 Malays (288 maxillary sinuses) with no clinical evidence of craniofacial and maxillary sinus abnormalities were selected. The subjects aged from 0.4 to 30 years (mean = 13.7 ; SD = 8.53), underwent the CT scanning using Ge...

Ridge atrophy accompanied by the pneumatization of maxillary sinus in the maxillary posterior region may lead to inadequate bone height, thereby precluding implant placement. Therefore, it may be mandatory to perform a sinus membrane elevation procedure and augmentation in the bone. The present study aimed to introduce a novel modification method for sinus floor elevation using a gelatin sponge...

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...
