BACKGROUND The correlation between facial and/or head pain in patients clinically suspected of having sinusitis and actual localized findings on sinus computed tomographic (CT) imaging are poorly understood. OBJECTIVE To prospectively evaluate the relationship of paranasal sinus pain symptoms with CT imaging. METHODS Two hundred consecutive patients referred by otolaryngologists and interni...

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...

Computerised tomography (CT) scan imaging techniques acts as a guide for functional endoscopic sinus surgery (FESS). It plays a vital role in the successful outcome of the treatment and management of the paranasal sinus variations. The frequent predisposing factors of chronic sinusitis are the anatomical variations of the paranasal sinus and nasal region. Computed tomography (CT) scan plays a f...

It seems apparently that the 2 separate anatomical areas (nasal cavity and paranasal sinus mucosa) are indeed one single unit with an identical behavior during inflammatory process. Similar histopathologic evidence in long-term condition could emphasize on the concept of rhinosinusitis in patients with inflammatory paranasal sinus disease. Prospective study was performed on 50 consecutive patie...

Allergic mucin is described as thick, peanut butter-like mucus impacted in the paranasal sinuses of patients with allergic fungal rhinosinusitis. The presence of allergic mucin in the middle ear has never been reported. We encountered a 65-year-old female with allergic mucin found impacted in her left middle ear and mastoid cavity during revised tympanoplasty surgery at our institute. Bilateral...

OBJECTIVES/HYPOTHESIS Fungus balls are a common disease of the paranasal sinuses, usually involving the maxillary sinus. To clarify the pathology, we analyzed patients treated for maxillary sinus fungus balls to see whether the latter correlated with dentogenic factors. STUDY DESIGN Retrospective case analysis. METHODS Cases of maxillary sinus fungus balls diagnosed between January 2000 and...

Due to the insidious onset and common symptoms, the diagnostic of sinonasal tumors is late in the evolution. Usually, at that time, the preferred endoscopic approach alone is not recommended, therefore a mixed openendoscopic approach appears to be the best choice in terms of exposure of the tumor and a clear margin resection. The purpose of this case report study is to demonstrate the necessity...

Neuroendocrine neoplasms are defined as epithelial neoplasms with predominant neuroendocrine differentiation. They can arise in almost every organ of the body although they are most commonly found in the gastrointestinal tract and respiratory system. Nasal cavity and paranasal sinuses are a rare site for neuroendocrine carcinoma. In contrast to the other regions, neuroendocrine tumours of the s...

Mycobacterium gordonae is often regarded as a weak pathogen that only occasionally causes overt disease. We report a case of M. gordonae infection in the facial skin, nasal mucosa, and paranasal sinus in an immunocompetent patient and review previous cases. The T-SPOT.TB test might be useful in diagnosing such cases.

A comprehensive study that compared acoustic rhinometry (AR) data to computed tomography (CT) data was performed to evaluate the accuracy of AR measurements in estimating nasal passage area and to assess its ability of quantifying paranasal sinus volume and ostium size in live humans. Twenty nasal passages of 10 healthy adults were examined by using AR and CT. Actual cross-sectional areas of th...
