Paragangliomas are tumors of the autonomic nervous system, arising from paraganglionic tissue. Paragangliomas of the head and neck region are very rare. In the head and neck, the most common sites of origin of this neoplasm are the carotid body, the jugular bulb and the vagal body. Paragangliomas of the nose and paranasal sinuses are very uncommon. The authors referred one case of nasal paragan...

In 2002 there were about 144 000 new cases of head and neck squamous cell cancer (HNSCC) in Europe and 69 000 deaths, making it the seventh leading cause of cancer death [1]. HNSCC arise from the mucosa of the upper aerodigestive tract. They include cancers of the oral cavitiy, the pharynx (naso-, oroand hypopharynx), the larynx and the paranasal sinuses. The head and neck region includes diffe...

The complex regional anatomy of the nose and paranasal sinuses makes the interpretation of imaging studies of these structures intimidating to many radiologists. This paper aims to provide a key to interpretation by presenting a simplified approach to the functional anatomy of the paranasal sinuses and their most common (and most relevant) variants. This knowledge is basic for the full understa...

Cholesterol granulomas are common in the mastoid antrum and air cells of the temporal bone. In the paranasal sinuses, especially in the frontal sinus, they have occasionally been mentioned in the literature. The pathogenesis is unknown, but the majority of the authors support the concept of airway obstruction in the cells well pneumatised of temporal bone and paranasal sinuses. The authors repo...

Burkitt's lymphoma is a highly aggressive small B-cell lymphoma. The treatment of choice is complex chemotherapy. As a rare tumor in the head and neck area, Burkitt's lymphoma usually involves cervical lymph nodes, and only fewer than 25% of cases involves extranodal regions. Involvement of the paranasal sinuses has been reported in only 14 cases in the past century. We describe here two patien...

In this prospective study we compared the efficiency of azithromycin and amoxicillin-clavulanate in treatment of acute sinusitis in children. Seventy patients were included in the age between 5 and 15 years. Beside ENT and pediatricians examination, nasal and throat smear on culture and antibiogram is taken from all the patients, as well as, X-ray of paranasal sinuses and laboratory findings, f...

Metastatic tumors in the paranasal sinuses are very rare. The origin of metastatic tumors in the paranasal sinuses is often renal cancer. Renal cell carcinomas are known for their tendency for early metastasis, and symptoms due to the metastatic lesion may be the only initial manifestation. In this paper, we deal with the case of a 35-year-old male patient who presented with a mass in the left ...
