AIM To describe vascular anatomy of the maxillary sinus in dentate specimens dissected from human cadavers. METHODS Twenty dentate maxillary specimens were dissected, anatomically prepared, and injected with liquid latex for a better visualization of the maxillary sinus artery. RESULTS We found an intraosseous anastomosis in 100% and an extraosseous anastomosis in 90% of the cases. The ante...

background and aim . vertical and horizontal bone resorption of the alveolar ridge are common in edentulous jaws. in the distal area of the maxilla, an adequate bone volume is often lacking because of the proximity of the sinus cavities to crestal bone. sinus floor augmentation is an established way of increasing the height and volume of bone in the posterior region of the maxilla, which increa...

background: maxillary sinuses are covered by a 1 mm thick mucous membrane that when this membrane becomes infl amed, the thickness may increase 10-15 times. the common causes of odontogenic sinusitis are dental abscesses and periodontal disease. computed tomography (ct) is considered the gold standard for sinus diagnosis. recently, cone beam computed tomography (cbct) has been introduced for de...

PURPOSE The aim of this study was to evaluate the rate of complications in maxillary sinus augmentation surgery and the impact of complications on subsequent implant treatment in a patient population with severe maxillary atrophy scheduled for treatment under general anesthesia. MATERIALS AND METHODS The study population consisted of 70 patients (124 sinuses) with severe maxillary atrophy who...

OBJECTIVES In the paranasal sinus fungal ball (SFB), changes that occur in the underlying bone have not been well described. Recently, bacterial coinfection has been reported in patients with paranasal SFB. We evaluated whether bone changes occur in patients with unilateral maxillary SFB, and also how bacteria in an SFB affect the bony wall of the sinus. METHODS A retrospective study of patie...

Background For dental implant planning in maxillary posterior region, it is essential to know their relationship with maxillary sinus. Maxillary posterior teeth affected by chronic periodontitis usually have a poor prognosis, ultimately leading to tooth loss. Following tooth loss, significant bone resorption occurs resulting in compromised remaining bone support for dental implant placement. ...

The paranasal air sinuses and nasal cavities were studied along with other cephalic spaces (brain cavity, paratympanic sinuses) in certain dinosaurs via CT scanning and 3D visualization to document the anatomy and examine the contribution of the sinuses to the morphological organization of the head as a whole. Two representatives each of two dinosaur clades are compared: the theropod saurischia...

Introduction: Maxillary sinus lift combined with implant placement without grafting allows bone formation in the sinus. However, bone volume in severely atrophic maxilla is often insufficient to ensure initial stability of implants. The purpose of this study was to evaluate the outcome of maxillary sinus augmentation by graft-free two-stage sinus lift using titanium bone fixation device and imp...

OBJECTIVE To assess the frequency of nodal involvement and its prognostic value in malignant tumors of the paranasal sinuses, particularly in maxillary sinus squamous cell carcinoma. DESIGN Retrospective review. SETTING Tertiary cancer center. PATIENTS The medical records of 704 consecutive patients surgically treated for malignant tumors of the paranasal sinuses from January 1968 to Marc...

Variability of the bony structures located in the maxillary sinus, and of the lateral nasal wall topography, have practical significance during surgical procedures conducted by maxillofacial surgeons or otolaryngologists. The retrospective analysis of 111 computed tomography examinations of patients (52 male and 59 female) diagnosed in our institution was made to evaluate anatomical variations ...
