Background This study aimed to present the correlation between headaches and anatomical changes within nasal cavity paranasal sinuses. Material methods: includes a literature search our observations of 24 patients regarding with sinus anatomy.

The paranasal sinuses and the mastoid air-cell systems are evaginations of the mucous membrane of the nasal and nasopharyngeal cavities . Separate theories regarding their pneumatization have been suggested. However, correlation studies between the two systems giving a possible clue to a common pneumatizing process have been few (1 , 2]. One hundred adult patients without ear disease and minima...

Meningiomas are well-recognized tumors of the central nervous system. Extracranial meningiomas, secondarily extended into the paranasal sinuses, are rare tumors, comprising approximately 2% of all meningiomas. Extracranial meningiomas of the paranasal sinuses may present a diagnostic and the rapeutic challenge. We present a retrospective review comprising three cases and discuss the clinical pr...

Several articles have been written about hyper infl ated sinus structures. Never before, however, a complete overview of all possible pressure induced variations of sinus anatomy have been published. The aim of this study was to make an inventory of the most common CT signs of hyper infl ated paranasal sinus structures. During a period of 2 years all CT-scans of the paranasal sinuses made in an...

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...
