STATEMENT OF THE PROBLEM Anatomic variation can potentially impact the surgical safety. PURPOSE The purpose of this cross-sectional study was to assess the prevalence of ostiomeatal complex variations based on cone beam computed tomography (CBCT) images of the patients seeking rhinoplasty. MATERIALS AND METHOD In this cross-sectional study, CBCT images of 281 patients including 153 female a...
OBJECTIVES New digital two-dimensional imaging systems are considered as an easily accessible modality for sinonasal evaluation. The aim of this study was to assess the diagnostic efficacy of digital Waters' and Caldwell's radiographic views for evaluation of sinonasal area. MATERIALS AND METHODS A total of 273 patients fulfilling the inclusion criteria were enrolled in this descriptive-analy...
W1 Thickening of small bowel folds (> 3 mm) can be caused by any process that increases the volume of fluid or cells in the submucosal or mucosal region (Table 1). The critical diagnostic observation is whether the general pattern of the thickening is regular or irregular. Regular thickening of small bowel folds, which are perpendicular to the bowel lumen and parallel to neighboring folds, is u...
An enlarged pneumatized middle turbinate, called a concha bullosa, may be the site of inflammatory disease ranging from simple mucosal thickening to a mucocele. Four patients with inflammatory disease involving a concha bullosa were studied with MR and/or CT. Both imaging techniques detected the presence of mucosal inflammation and a mucocele within the concha bullosa, but CT better demonstrate...
OBJECTIVES. To assess the presence of anatomic variations and pathology of the maxillary sinus using cone beam computed tomography (CBCT) of the maxilla where pre- implant surgery is planned. MATERIAL AND METHODS. This retrospective study evaluates a sample CBCT scans of 34 dental patients (68 sinuses). CBCT is used to assess maxillary sinus mucosa and outflow and prevalence of septa. The mucos...
BACKGROUND Continuous aspiration of subglottic secretions is effective in preventing ventilator-associated pneumonia, but it involves a risk of mucosal damage. The main objective of our study was to determine the incidence of airway complications related to continuous aspiration of subglottic secretions. METHODS In consecutive adult patients with continuous aspiration of subglottic secretions...
BACKGROUND Although common variable immunodeficiency (CVID) is associated with sinopulmonary disease, there are no previous systematic evaluations comparing computed tomographic (CT) sinus imaging with immunoglobulin measurements in patients with this condition. METHODS We performed a retrospective review by a blinded observer using the Lund-Mackay numerical scoring scale as well as a visual ...
