Solitary extramedullary plasmacytomas (EMPs) are nonepithelial neoplasms of plasma cell origin categorized among non-Hodgkin lymphomas, without the bone marrow involvement and systemic spread seen in multiple myeloma. They are uncommon tumors comprising 3% of all plasma cell neoplasias. Although they usually occur in the upper respiratory tract, only 1 case of EMP localized to the frontal sinus...

OBJECTIVE We evaluated the extent of asymmetry evident in paranasal sinus computed tomography (CT) scans of Turkish patients without sinusitis in the ethmoid roof. Our data contribute to the body of knowledge on the subject. MATERIALS AND METHODS We retrospectively studied multiplanar reformatted CT images of the paranasal sinus (1-mm sections) from 110 patients (50 male, 60 female). Ethmoid ...

Aim: This study aimed to find the effect of preoperative tumor embolization and transnasal endoscopic excision of a sphenoid sinus angiofibroma on the postoperative outcome. Case Report: A thirteen year old male presented to the Outpatient ENT Department of a tertiary care centre, with a history of recurrent left-sided spontaneous painless epistaxis since one year. Diagnostic Nasal Endoscopy sh...

This paper reports a case of septic cavernous sinus thrombosis following a chronic ear infection and paranasal sinusitis. The diagnosis and management of this condition are discussed.

INTRODUCTION Frontal sinus mucoceles are the commonest among all paranasal mucoceles. With introduction of functional endoscopic sinus surgery, surgeons prefer endoscopic management of sinus mucoceles, but lesions that appear in the lateral part of the frontal sinus can be difficult to access and often need external approaches. CASE PRESENTATION We described a lateral frontal sinus mucocele w...

The sinus sphenoidalis is the paranasal sinus most centrally located in the skull base and known to vary extremely in dimensions. A very large volume of the sinus visible on skull radiographs is called sinus 'hyperaeration'. This finding has been described many times in the literature, but is generally rare. The term 'pneumosinus dilatans' is synonymously used to address an unexpectedly large p...

Polymorphous low-grade adenocarcinoma is a malignant epithelial tumour with low metastatic rate and infiltrative growth pattern. The palate is the most common site. Paranasal sinuses are uncommon venues for polymorphous low-grade adenocarcinoma. Here, we report a polymorphous low-grade adenocarcinoma case of the maxillary sinus, a very rare location. Although it is a low grade ...

To investigate the claim that the primate paranasal sinuses possess not a functional but a structural role associated with the skull architecture (Blaney, 1990), the relationship between the maxillary sinus and the skull architecture was studied ontogenetically in 30 skulls of male and female Japanese macaques (Macaca fuscata). Coronal CT scan series and computerised 3-dimensional images served...
