OBJECTIVE To report clinical characteristics and treatment outcomes of actinomycosis of the paranasal sinus. STUDY DESIGN Retrospective review. SUBJECTS AND METHODS The medical records of six patients with actinomycosis of the paranasal sinus between 1998 and 2006 were analyzed. RESULTS There were no immunocompromised patients and all lesions were unilateral. Only one patient had a histor...

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 nasal cavity, paranasal sinuses, and nasopharynx are sites for a wide variety of tumors and non neoplastic conditions. Inverted papilloma accounts for about 0.5-4% of total nose and paranasal sinus tumours. Men are affected 4 times more often than women. The major types are fungiform papilloma, inverted papilloma, and oncocytic Schneiderian papilloma. The latter has often been referred to a...

OBJECTIVE To review the oncologic outcomes in patients with advanced (stage III-IV) squamous cell carcinoma of the paranasal sinuses treated with induction chemotherapy prior to definitive local therapy. METHODS The medical records of 46 consecutive patients with previously untreated, biopsy-proved squamous cell carcinoma of the paranasal sinuses who received induction chemotherapy during the...

OBJECTIVE Immunoglobulin G4 (IgG4) related sclerosing disease (RSD) of the paranasal sinuses is a rare lesion of dense lymphoplasmacytic tissue, with a high proportion of IgG4+ plasma cells. We presented a rare case of IgG4-RSD with isolated involvement of the paranasal sinuses in the absence of multiorgan involvement. METHODS A case report and comprehensive literature review. RESULTS To ou...

The paranasal sinuses are known to be a rare location for metastasis. Renal cell carcinoma (RCC) is the most frequent primary tumor to metastasize to the sinonasal region, followed by lung and breast cancer. In particular, clear cell type RCC, which represents approximately 85% of RCCs, is characterized by early metastasis, and it sometimes spreads to unusual sites (1, 2). Metastatic tumors in ...

Endonasal endoscopic sinus surgery is the standard procedure for surgery of most paranasal sinus diseases. Appropriate frame conditions provided, the respective procedures are safe and successful. These prerequisites encompass appropriate technical equipment, anatomical oriented surgical technique, proper patient selection, and individually adapted extent of surgery. The range of endonasal sinu...
