Posttransplantation lymphoproliferative disorder (PTLD) is a challenging complication associated with organ transplantation and is usually fatal if untreated. We describe the case of a transplant recipient who presented with rapidly progressive cranial nerve palsies due to PTLD that originated in the sphenoid sinus. In this case, the clinical and radiologic presentation of PTLD mimicked invasiv...

PURPOSE The aim of this study was to investigate paranasal sinus pathoses detected on cone-beam computed tomography (CBCT) in an adult population. PATIENTS AND METHODS Three observers retrospectively inspected 353 consecutive CBCT scans obtained in a dentomaxillofacial radiology department for paranasal sinus pathoses. Descriptive statistics and chi-square tests were used to determine the pre...

Skull base osteomyelitis (SBO) is typically bacterial in origin and caused by Pseudomonas, although the fungus Aspergillus has also rarely been implicated. SBO generally arises from ear infections and infrequently complicates sinonasal infection. Rhinocerebral Mucor infection is characteristically an acute, fulminant, and deadly infection also affecting the orbits and deep face and is associate...

Background and Aim: Over the past 2 decades, endoscopy has become an integral part of the surgical repertoire for pituitary procedures and over the past several decades, the endoscopic endonasal trans sphenoidal approach (EETA) has gradually become an accepted option for pituitary tumors with intra-,supra-,and para-sellar location and extension, because of its minimal invasiveness and high effi...

INTRODUCTION Dental pain originating from the maxillary sinuses can pose a diagnostic problem. Periapical lesion development eliciting inflammatory changes in the mucosal lining can cause the development of a sinusitis. The purpose of this study was to describe the radiographic characteristics of odontogenic maxillary sinusitis as seen on cone-beam computed tomography (CBCT) scans and to determ...

PURPOSE The aim of this study was to investigate how clinical features such as sex, age, etiologic factors, and presenting symptoms of odontogenic sinusitis are differentiated from other types of sinusitis. Also, this study was designed to find methods for reducing the incidence of odontogenic sinusitis. MATERIALS AND METHODS A retrospective chart analysis was completed on twenty-seven patien...

UNLABELLED Hematopoietic Stem Cell Transplant (HSCT) causes immunosuppression and predisposition to sinusitis. CT scans are complementary exams used in the diagnosis of sinusitis; however, its use in every patient is questionable. AIM to check the usefulness of ordering a CT scan prior to HSCT and to study the relationship between anatomical variations and sinusitis. METHOD prospective stud...

OBJECTIVE To study the point prevalence of allergic rhinitis and sinusitis in childhood asthma and to examine the relationship among them. METHODS In 250 children (age <13 y) with mild-to-moderte asthma, allergic rhinitis was diagnosed by clinical plus nasal eosinophilia criteria, and sinusitis was diagnosed clinically plus confirmation by computerized tomography scan. RESULTS The point pre...

OBJECTIVE To review and report diseases of the sphenoid sinus from the literature and from a university hospital. METHODS Inpatients' data were retrospectively gathered and reviewed from January 2006 to June 2016. Clinical data, imaging, organisms, and pathological reports were collected. Pathology was divided into infection/inflammation, tumor, and miscellaneous. A literature review was perf...

We aimed to determine the position, number and variability of the sphenoid sinus ostia. A total of 32 dry skulls were examined under x6 magnification. The septum and nasal turbinates were removed to expose the anterior wall of the sphenoid sinus. A caliper was used for measurements. We found 2 ostia per skull, except for one (3%), in which the left ostium was absent. The inferior edges of both ...
