Nasal glial heterotopia (nasal glioma) is the term used to describe a mass made up of mature brain tissue that is isolated from the cranial cavity or spinal canal. Most of these rare, benign, congenital tumors are found in the nasal region, particularly at the bridge of the nose and in the nasal cavity. Nasal glial heterotopia is frequently diagnosed in newborns; a few cases have been found in ...

Internal cranial anatomy is a challenging area to study in fossilized skulls because of small sample sizes and varied post-mortem preservational alterations. This difficulty has led to the lack of correspondence between results obtained from direct osteological observation and from more indirect reconstruction methods. This paper presents corroborating evidence from direct osteological observat...

Glomangiopericytoma/sinonasal type hemangiopericytoma is a rare sinonasal neoplasm arising from the pericytes surrounding capillaries and accounts for less than 0.5% of all sinonasal tumors. This tumor differs from conventional soft tissue hemangiopericytoma in location, biologic behaviour and histologic features. Glomangiopericytoma is a borderline low malignancy tumor with a good prognosis af...

OBJECTIVE To correlate objective assessment of nasal obstruction, as measured by acoustic rhinometry (volume of the first 5 cm of the nasal cavity) and active anterior rhinomanometry (total nasal airway resistance), with its subjective evaluation (obstruction scores). METHOD Thirty patients, aged 7 to 18 years, with persistent allergic rhinitis and thirty controls were enrolled. The obstructi...

We have recently shown that unilateral naris occlusion (UNO) causes an increase in olfactory marker protein (OMP) immunoreactivity (IR) in mouse olfactory sensory neurons (OSN) from the occluded side of the nasal cavity and a decrease in OMP-IR on the non-occluded side, relative to controls. Given OMP's demonstrated role in olfactory modulation, these OMP-IR changes have been interpreted as a c...

background and objective: nasal polyp is the most common benign mass of the nasal cavity and it is originated from nasal cavity or sinuses. cytokeratins (ck) are intermediate filament proteins that provide mechanical support in epithelial cells. the purpose of this study was to compare the expression of cytokeratin 7 in epithelium of nasal polyps and nasal mucosa in chronic rhinosinusitis. mate...

This study represents an unusual case of mucormycosis localized in nasal cavity of a German shepherd dog. The patient was a 1-year-old male guard dog with unilateral nasal epistaxis, mucopurulent nasal discharge, sneezing and nose pawing. The dog had a history of head trauma about 2 months before admission, which was associated with mild self-limited epistaxis. Initial nasal rhinoscopy showed s...

OBJECTIVES To study the circumstances of diagnosis, imaging techniques and therapeutic management of cavernous hemangioma of the nasal cavity. MATERIAL AND METHOD We report the case of a 60-year-old woman, who presented epistaxis CT scan and nasal obstruction. RESULTS Rhinoscopy showed a purplish, regular mass that filled the left nasal cavity. Computed tomographic and MRI images showed the...

Introduction: This study was done to determine the site of obstruction in lacrimal drainage system in Asian patients suffering from epiphora and to determine the transit time taken for the tracer material to reach the lacrimal sac and the nasal cavity. Methods:Dacryoscintigraphy was performed using radionuclide technetium-99m pertechnetate (99m...
