tomographic findings of maxillary retention cysts

Aim: The aim was to assess the presence of incidental-findings (IFs) on cone-beam computed tomography (CBCT) scans of faciomaxillary region with emphasis on gender and ethnicity. Materials and methods: A retrospective analysis of incidental findings (IFs) in the maxillary sinus was performed. All CBCT-scans were performed using a Cone Beam 3D imaging system and examined using a software program. These images were taken for treatment planning for dental implant therapy of partially edentulous individuals...

INTRODUCTION: The maxillary sinus can be affected by dental infections because of its close relationship with upper teeth. This study aimed to assess the most common types of maxillary sinus alterations and to associate them with odontogenic conditions using cone-beam computed tomographic (CBCT) images. METHODS: CBCT scans of 400 patients showing sinus disease in 1 or both maxillary sinuses were evaluated. Sinus alteration was considered as follows: generalized or localized mucosal thickening (MT), maxillary sinusitis (MS), and retention cysts (RCs)...

BACKGROUND: The correlation between facial and/or head pain in patients clinically suspected of having sinusitis and actual localized findings on sinus computed tomographic (CT) imaging are poorly understood. OBJECTIVE: To prospectively evaluate the relationship of paranasal sinus pain symptoms with CT imaging. METHODS: Two hundred consecutive patients referred by otolaryngologists and internists for CT of the paranasal sinuses participated by completing a questionnaire immediately before undergoing CT...

OBJECTIVE: To report two cases of sinusitis-associated radioiodine uptake in patients with thyroid cancer and to review the reported causes of false-positive radioiodine uptake in the head and neck area. METHODS: We present the radiologic findings in two patients who had undergone treatment for papillary thyroid cancer and discuss other settings in which radioiodine uptake suggested the presence of metastatic disease. RESULTS: Radioiodine whole-body scans of two patients who had had thyroid cancer demonstrated uptake in the sphenoid and maxillary sinuses, respectively, mimicking bone or brain metastatic involvement...
