Última Anatomic Variations of Sphenoid Sinus Pneumatization in a Sample of Turkish Population: MRI Study 77 Sevinc,Ozdemir; Is,Merih; Barut,Cagatay; Erdogan,Aliriza. There are a number of variations regarding morphometric anatomy and degree of pneumatization of the sphenoid sinus. In our study, we planned to examine and show the differences of pneumatization of the sphenoid sinus particularly to guide the neurosurgeon during transsphenoidal surgery. Sagittal T1-weighed spin-echo Magnetic Resonance Images (MRIs) of 616 adult individuals (406 women and 210 men) were analyzed, retrospectively. According to the collected data from our study, the most common type of the sphenoid sinus was the sellar type (83%; n=511) for the whole study group. Of the 616 individuals 16.6% (n=102) had presellar type and 0.5% (n=3) had conchal type of sphenoid sinus. Preoperative detailed detection of the anatomical characteristics of...

The sinonasal region in humans is one of the regions that commonly shows anatomical variations. These variations can be easily diagnosed by paranasal CT evaluation. One of these variations is Crista galli pneumatization. In recent years, there have been opinions supporting the hypothesis that pneumatization originates from the frontal sinus. In this study, we planned to evaluate whether the presence of Crista galli pneumatization varied in pre-adult and adult periods. In this retrospectively designed study, 218 coronal paranasal CT images collected between 2012 and 2013 were evaluated. Patients were divided into two groups according to age under or over 18 years. In the group under the age of 18 (97 cases), pneumatization was detected in 2.1 % of samples,...

Ano: 2016 URL: http://www.scielo.cl/scielo.php?script=sci_arttext&pid=S0717-95022016000200021 Pneumatization of Mastoid Air Cells: Role of Acquired Factors 77 Sethi,Ashwani; Singh,Ishwar; Agarwal,A. K; Sareen,Deepika. The exact mechanism of the pneumatization of the mastoid air cell system and the factors influencing the pneumatization are poorly understood. Both genetic as well as acquired factors have been implicated to influence this pneumatization process. Since pneumatization of the mastoid air cell system is considered an important prognostic factor in the outcome of reconstructive ear surgeries, a cohort study was carried out to assess the role of two important acquired factors i.e. duration of chronic otitis media and auditory tube functional status on the pneumatization of mastoid air cells. 50 individuals with unilateral chronic otitis media underwent assessment of their mastoid air cell system using planimetry and auditory tube functions using flourescein dye...
