Novel Vascularized Pedicle Flaps for Dural Reconstruction via Endoscopic Transorbital Approach: Temporalis Muscle and Pericranial Flaps.

Background: The endoscopic transorbital approach (ETOA) has emerged as a valuable minimally invasive technique in skull base surgery, providing direct access to the anterior and middle cranial fossae. However, effective reconstruction of dural defects remains a significant technical challenge. This study evaluates the feasibility and anatomical characteristics of temporalis muscle flaps (TFs) and pericranial flaps (PFs) for dural reconstruction following ETOA, using cadaveric models.

The Effect of Corticosteroids on Sinus Microbiota in Chronic Rhinosinusitis Patients with Nasal Polyposis.

Background: Chronic rhinosinusitis with nasal polyposis (CRSwNP) is a multifactorial disease with no known single cause, but it is thought that bacteria play a role in the disease process.

Objective: This pilot study aims to assess the longitudinal effect of corticosteroid therapy on sinus microbiota in chronic rhinosinusitis patients with nasal polyposis (CRSwNP).

Methods: A longitudinal prospective case-control study was done on patients with CRSwNP and healthy controls.

Impact of body mass index on survival outcome in patients with differentiated thyroid cancer.

Introduction: Increased body mass index is known to be associated with the high prevalence of differentiated thyroid cancers; however data on its impact on survival outcome after thyroidectomy and adjuvant therapy is scanty.

Objective: We aimed to evaluate the impact of body mass index on overall survival and disease free survival rates in patients with differentiated thyroid cancers.

Methods: Between 2000 and 2011, 209 patients with differentiated thyroid cancers (papillary, follicular, hurthle cell) were treated with thyroidectomy followed by adjuvant radioactive iodine-131 therapy and thyroid-stimulating hormone suppression.

Obesity and associated risk factors among students of health colleges of King Saud University, Saudi Arabia: A cross-sectional study.

Objective: To determine the prevalence of obesity and associated risk factors among medical students in Saudi Arabia.

Methods: The cross-sectional study was conducted from December 2012 to March 2013 at King Saud University, Riyadh, Saudi Arabia. Using stratified sampling technique, undergraduate students of either gender from the health colleges were included.
