The Correlation Between Vitamin D Deficiency and Chronic Rhinosinusitis: A Systematic Review.

Chronic rhinosinusitis (CRS) is marked by inflammation of the paranasal sinuses and mucosal lining of the nose. CRS can be classified as CRS with nasal polyps or CRS without polyps. In recent years, there has been increased attention on the immunological role of vitamin D in treating CRS, coupled with the observation of vitamin D deficiency among CRS patients.

Mucocele of the Paranasal Sinuses: Retrospective Analysis of a Series of Eight Cases.

Background:  Paranasal sinus mucoceles are epithelium-lined cystic masses usually resulting from obstruction of sinus ostia. They most frequently occur in the frontal and ethmoid sinuses. The etiology is not clarified, but the most common identifiable cause of mucoceles following functional endoscopic sinus surgery (FESS), trauma, neoplasms, and allergy.

Orbital Complications of Extensive Allergic Fungal Rhinosinusitis: A Case Report.

Allergic fungal rhinosinusitis is an immunoglobulin E-mediated disease caused by fungal antigens. Orbital complications due to bone erosion by the expanding, mucin-filled sinuses are considered uncommon, but they require immediate intervention. We report a successful management of a complicated case of allergic fungal rhinosinusitis in a 16-year-old female complaining of progressive nasal obstruction for four months, who only sought medical advice after developing proptosis and visual affection.

Impact of Preoperative Steroids Administration on Endoscopic Sinus Surgery: Systematic Review of Literature, and a Survey in Saudi Arabia.

There is limited knowledge in the literature and lack of clear protocols among practitioners regarding preoperative steroids administration for patients undergoing endoscopic sinus surgery (ESS). This study aimed to identify the practice patterns of rhinologists in Saudi Arabia as well as systematically review all health-related evidence regarding the use of preoperative steroids for ESS. A previously used questionnaire was modified and distributed in Saudi Arabia among rhinologists who finished their residency training.
