Objective: To assess tomographic features of mastoid cell pneumatization (MCP) using cone beam computed tomography (CBCT). Materials and Methods: evaluate 659 CBCTs (500 women 159 men) the Oral Maxillofacial Radiology service Universidad Peruana Cayetano Heredia Dental Clinic, between 2014 – 2015. The age group was 7 to 79 years-old. classification Al Faleh Ibrahim also used degree pneumatizati...

Introduction: The aim was to explore the developmental relationships between the angles of septal deviations and the degree of the mastoid pneumatization.   Materials and Methods: In total, 143 patients with a diagnosis of septal deviation who underwent septoplasty were included. The patients were divided into three groups in terms of the ...

Background: Over the past decades, instruments and techniques of the transsphenoidal approach have improved greatly. All of these procedures, whether microscopic or endoscopic, must pass through the sphenoid sinus to reach the lesions. The sphenoid sinus is surrounded by several vital anatomical structures. Knowing the details of the anatomy of the sphenoid sinus and the extent of pneumatizatio...

Considering the anatomical variability related to the maxillary sinus, its intimate relation to the maxillary posterior teeth and because of all the implications that pneumatization may possess, three-dimensional assessment of maxillary sinus pneumatization is of most usefulness. The aim of this study is to analyze the maxillary sinus dimensions both linearly and volumetrically using cone beam ...

Eight infants with radiographic and bone biopsy evidence of autosomal recessive osteopetrosis were evaluated by cranial CT. The clinical presentations and CT characteristics support the theory that this disorder exhibits severe and mild variants. At an early stage the severe variant demonstrates small optic canals, small orbits with proptosis, and a small nasoethmoid complex without significant...

A 49-year-old woman had a palpable mass in her occipital region. Plain radiographs and CT examination revealed extensive atlantooccipital pneumatization with findings consistent with the diagnosis of mastoid pneumocele. Decompression was achieved with placement of a myringotomy tube, resulting in prompt symptomatic relief. On a follow-up CT examination, the pneumatized areas had become opacifie...
