A 38-year-old male presented with a slowly progressive and painful swelling in the right cheek. On palpation, a firm, fixed and tender mass was detected over the right maxilla, with normal overlying skin. Endoscopic examination revealed a submucosal mass protruding into the right nasal cavity along the lateral wall, extending from the vestibule to the sphenoid sinus. Computed tomography showed ...

Malignant lymphoma is a malignant tumor that occurs in the lymphocytes but can also occur anywhere body. On other hand, lymphomas originating from nasopharyngeal space are very rare. We experienced case of 84-year-old female patient with huge mass, who had no complaints than right nasal congestion, intermittent rhinorrhea, and sneezing. A physical examination revealed large, polypoid, transpare...

Teratomas are neoplasms derived from the germ cell with components of all the three embryonic layers. These are rare neoplasms in head and neck region which can occur in any age group but are more prevalent in children. The present case is an 11-year-old girl who was brought with history of painless and progressive swelling in the oropharynx for 3 years with the associated left sided nasal bloc...

BACKGROUND Nasal cycling may present negative consequences for oxygen-dependent patients using a nasal cannula. This study investigates the effects of nasal cycling on the delivered F(IO2) via nasal cannula in an anatomic model following a baseline study comparing right and left prong nasal cannula oxygen flow delivery. METHODS Flow from right and left nasal cannula prongs were measured simul...

Chordomas are malignant, nonepithelial neoplasms derived from notochordal tissue. A primary chordoma of the nasal cavities and paranasal sinuses is extremely rare compared with clival chordomas, which often present as nasal masses after spreading anteriorly. Only a few cases of primary chordoma of the nasal cavities and paranasal sinuses have been reported in the literature. We report a case of...

The nasal glioma is a rare congenital nasal abnormality, which manifests as a mass of extracranial cerebral tissue unconnected with the brain. The clinical entity is challenging for several reasons. Their diagnosis may not be immediately obvious at presentation. It is important to exclude an intracranial extension, and for this some have suggested a craniotomy. We report a case of extranasal gl...

BACKGROUND Angioleiomyoma of the nasal cavity is an extremely rare benign neoplasm. It usually occurs in the lower extremities. Up to date, only few cases of angioleiomyoma have been reported. First case of angioleiomyoma of nasal cavity was reported in 1966. We report a rare case of angioleiomyoma arising from the right maxillary sinus. CASE REPORT A 43-year-old lady presented with recurrent...

Breathing route during sleep has been studied very little, however, it has potential importance in the pathophysiology of sleep disordered breathing. Using overnight polysomnography, with separate nasal and oral thermocouple probes, data were obtained from 41 subjects (snorers and nonsnorers; 25 male and 16 female; aged 20-66 yrs). Awake, upright, inspiratory nasal resistance (Rn) was measured ...
