objectives: to compare the thickness of the lateral wall of the maxillary sinus in individuals with and without teeth to determine if extraction of the teeth can lead to a significant reduction in the thickness of the maxillary sinus lateral wall or not. patients and methods: in a retrospective study on fifty patients with an edentulous space, the thickness of the lateral wall of the maxillary ...

AIM The study aimed to investigate the proximity of maxillary posterior teeth roots to maxillary sinus and measure the distance of maxillary posterior teeth roots and the sinus floor as well as the thickness of bone between the roots and alveolar cortical bone using Denta scan®. MATERIALS AND METHODS The study samples include Denta scan® images of fifty patients with normally erupted bilatera...

BACKGROUND We report a rare case of fatty tissue within the maxillary sinus in a 21-year-old woman, with a history of several previous punctures of the maxillary sinus. CASE PRESENTATION Clinical data of the patient was analysed retrospectively. The patient presented with symptoms of left-sided chronic maxillary sinusitis and had undergone several punctures of the left maxillary sinus 18 mont...

BACKGROUND Small cell neuroendocrine carcinoma of the maxillary sinus, a rare malignant tumor, has a poor prognosis because of its high incidence of metastasis. Moreover, metastatic cancer-induced hepatic rupture, characterized by hemoperitoneum, is infrequent, although several lines of evidences have reported that a wide variety of other neoplasms can cause this usually fatal manifestation. ...

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...

tumefactive fibroinflammatory lesions (tfls) are rare idiopathic benign fibrosclerosing lesions that clinically simulate a malignancy. tfls are seen more frequently in males between 10 and 74 years of age. the usual site of involvement is the head and neck region, but rarely the extremities may be involved. coexisting fibrosclerotic processes have been reported including retroperitoneal fibrosi...

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...
