PURPOSE The types and ratio of anterior clinoid process (ACP) pneumatization in paranasal sinus Multidetector Computerized Tomography (MDCT) were investigated the importance of ACP in neurosurgical approaches discussed. METHODS Paranasal MDCT images of 499 subjects (259 male, 240 female), between 17 and 65 years of age, were included in the study. Presence and types of pneumatization of the A...

Pneumatization of the petrous apex was investigated in 226 subjects without middle ear disease by means of target imaging CT. The degree of pneumatization of all subjects was 32.7% (148/452 ears), but no difference in degree was revealed with distinction of bilateral ears or between sexes. In 148 ears with pneumatization of the petrous apex, a higher degree of pneumatization was found in larger...

The temporal bone is used frequently to identify taxonomic affinities of genus Homo fossils based on external morphological features. In the meantime, the temporal bone pneumatization has rarely been examined, particularly in Asian Homo erectus. We put forward a comparative morphological and quantitative analysis in Asian Homo erectus from the sites of Ngandong, Sambungmacan, and Zhoukoudian, a...

OBJECTIVES/HYPOTHESIS The goal of this study was to present a classification based on the degree of pneumatization of the sphenoid sinus in the coronal plane that can be used to instruct preoperative planning for endoscopic endonasal surgery (EES). STUDY DESIGN Observational anatomical study. METHODS The geometry of sphenoid sinus pneumatization was characterized (n = 204 hemisinus) on high...

OBJECTIVE This study performed volumetric analysis and classified different repeated patterns of temporal bone pneumatization in adults using cone beam computed tomography (CBCT) scans. STUDY DESIGN A total of 155 temporal bones were retrospectively evaluated from 78 patients with no radiographic evidence of pathology. Two reference structures were used to classify temporal bone pneumatizatio...

BACKGROUND AND PURPOSE The crista galli is part of the ethmoid bone and, as such, it could be expected that aeration of the crista would come from ethmoid cells. After observing crista pneumatization from the frontal sinuses in several cases, we undertook this study to establish how often crista galli pneumatization came from the frontal sinuses rather than from the ethmoid complex. MATERIALS...

INTRODUCTION One of the aspects that have an influence on rhinosinusal endoscopic surgery is extrasinusal pneumatization, which can also affect less common structures at this level. The pneumatization of the superior and supreme turbinates, uncinate process and crista galli are perfect examples of this situation. The diagnosis is made only through imaging methods. MATERIALS AND METHODS This i...

OBJECTIVES/HYPOTHESIS Paranasal sinus pneumatization in patients with cystic fibrosis (CF) is less extensive compared to the general population and seems to be correlated to CF genotype. Interestingly, in CF patients temporal bone pneumatization (TBP) is more extensive compared to the general population, and middle ear pathology is generally uncommon in CF. It is debated whether TBP is influenc...

PURPOSE Maxillary sinus's inferior pneumatization is a physiological process, which increase with time and accelerates following extraction. The aim of this study was to determine the prevalence of nasal septal deviation (NSD), concha bullosa (CB), and Haller's cells (HC) and to examine the correlation of maxillary sinus inferior pneumatization (MSIP) with these anatomical variations. Material ...

The pneumatization of 141 "normal" temporal bones on computed tomography (CT) was evaluated in 100 patients (age range, 6-85 years). Because of the controversy surrounding the sclerotic squamomastoid (mastoid), temporal bones with this finding were discarded. A CT index of pneumatization was based on the pneumatized area and the number of cells seen within a representative scanning section. Res...
