Between November 2010 and December 2011, a certified radiologist retrospectively reviewed 510 computed tomographic images of the paranasal sinuses ordered by otolaryngologists at Okmeydanı Training and Research Hospital. Medical records, endoscopic nasal examinations, MRC size, and cyst: sinus size ratios were evaluated in patients with MRCs. The prevalence and characteristics of MRCs in the pa...

Polymorphous low-grade adenocarcinoma (PLGA) is a malignant neoplasm that tends to follow a benign clinical course. Recurrences are uncommon. We report a case of recurrent PLGA of the paranasal sinuses that manifested as a large mass that filled the entire nasal cavity and left maxillary sinus. To our knowledge, this is the first reported case of a recurrent PLGA of the paranasal sinuses.

BACKGROUND Exenteration is indicated in patients with malignant neoplasms of orbital contents. It entails the removal of the eyeball together with its extraocular muscles and other soft tissues. Exenterations can be classified into (1) total, (2) subtotal, and (3) supertotal exenteration. Retrospectively study, we reviewed 7 patients that had received exenteration/subtotal exenteration with spo...

This paper investigates the importance of including paranasal sinuses in the computational modeling of the nasal airflow. Three dimensional models of human nasal airway with and without including paranasal sinuses were reconstructed from Computed tomography (CT) axial images of a subject with healthy nasal airway. The reconstruction process was performed using MIMICS® software program. The airw...

The 2- and 3-dimensional (3D) anatomy and the morphometric properties of the paranasal sinuses of the foal have received little or no attention in the literature. The aim of this study was to obtain details of the paranasal sinuses using multiplane CT imaging to create 3D models and to determine morphological and morphometric data for the sinuses using the 3D models. The heads of five female fo...

Objective: A study to evaluate the effectiveness of the use of pre CT checklist in requesting CT paranasal sinuses for managing patients with Chronic Rhinosinusitis (CRS). Place and Duration: CT sinuses performed at Aberdeen Royal Infirmary from 20 Aug 2010 to 3rd Nov 2010 after the introduction of pre CT paranasal sinus request checklist. Methods: Prospective studies of patients undergoing CT ...

A unilateral tumour in the nasal cavity or paranasal sinuses is commonly caused by polyps, cysts, and mucoceles, as well as invasive tumours such as papillomas and squamous cell carcinomas. Schwannomas, in contrast, are rare lesions in this area (Minhas et al., 2013). We present a case of a 52-year-old female who presented with a 4-year progressive history of mucous hypersecretion, nasal obstru...

BACKGROUND Neuroendocrine carcinoma (NEC) of the paranasal sinuses is rare, accounting for 5% of sinonasal malignancies. The purpose of this study was to assess prognostic factors and survival rates for sinonasal NEC. METHODS A retrospective review of patients with NEC treated from 1990 to 2004 was performed. Patient demographics, TNM classification, treatment modality, recurrences, and survi...

.. Background: Endoscopic sinus surgery has become a preferred modality for management of various nasal and sinus disorders. Orbital complications, though rare, are reported amongst patients undergoing ESS. Study Design: Case series. Methods: A retrospective review was undertaken of four cases of orbital complications during endoscopic sinus surgery. Results: Two patients suffered from periorbi...

Mucormycosis is a rare opportunistic fungal infection. The most common infection site is the paranasal sinuses, although it can also occur in the lungs and skin. The fungus adheres to tissue membranes and forms thrombi, causing ischemia and hemorrhagic necrosis. Rhinocerebralmucormycosiscan occurin the nose, but mightrapidly spread to the orbit and intracranium. Therefore, prompt and aggressive...
