Sino-nasal synovial sarcomas are rare mesenchymal tumours, most arising primarily from the paranasal sinuses. Very few have been described with an extension to nasal cavity. Due a range of non-specific symptoms and local aggressiveness, diagnosis tends be confusing. Here we describe case primary sino-nasal monophasic sarcoma, diagnosed by histopathology treated excision adjuvant radiation thera...

conclusions surgeons should consider the possibility of existence of other mucoceles when they find a large downstream sinus mucocele obstructing the ostia of upstream sinuses on computed tomography scans. introduction mucoceles of the paranasal sinuses are relatively rare. a very busy otolaryngology department does not have more than a few cases each year. bilateral, multiple, and multiloculat...

ectopic eruption of teeth occurs in a variety of locations. commonly seen in palate and maxillary sinus, they have also been reported in nasal cavity, orbit, mandibular condyle, coronoid process, and facial skin. here, we report a rare case of recurrent sinusitis caused by ectopic tooth in right ethmoid sinus and successful endoscopic removal of it. the symptoms of the patient disappeared after...

Paranasal sinus mucoceles are benign cystic lesions, filled with mucus, occurring due to an obstruction of involved sinus ostium. They are indolent, locally expansive, and destructive. Surgical treatment must be performed and, when done at the correct time, may prevent sequelae. We present a case of ethmoid sinus mucocele with orbit involvement and permanent optical nerve injury.

A male patient aged 37 years with a history of cranioencephalic trauma 21 years ago, reports a left frontal tumor beginning 4 months ago. Magnetic resonance imaging revealed a lesion suggesting mucocele (Figure 1). The patient underwent endoscopic bilateral frontal ethmoid sinusectomy. The option was made for external left frontal ethmoidectomy due to intense bone sclerosis in the frontal reces...
