Preoperative Magnetic Resonance Elastography (MRE) of Skull Base Tumours: A Review.

Conventional magnetic resonance imaging (MRI) can detect tumors consistency, but it can't predict tumor stiffness or adherence of the tumor to nearby structures. Magnetic resonance elastography (MRE) is a known non-invasive MRI based imaging technique used to assess the viscoelasticity of the tissues particularly liver fibrosis. This study discussed the importance of preoperative MRE in skull base tumors and the future implications of this new imaging modality.

Nasal sinuses cholesteatoma: case series and review of the English literature.

Background: Nasal sinus cholesteatomas are uncommon slow-growing lesions that are frequently misdiagnosed preoperatively. They can develop due to embryologic remnants or iatrogenic factors (surgical trauma or nasal sinus trauma). In addition, they can cause bone destruction resulting in intracranial or intraorbital complications as well as malignant change if neglected.

Elective neck dissection in T1/T2 oral squamous cell carcinoma with N0 neck: essential or not? A systematic review and meta-analysis.

Introduction: Oral squamous cell carcinoma (SCC) is characterized by a high risk of cervical lymph node metastasis with a high incidence of occult metastasis. A strong debate is still present regarding the best treatment for early oral cavity cancer with N0 neck.

Objective: The aim of the present study was to compare between the results of elective neck dissection (END) and watchful waiting (observation or therapeutic neck dissection) in patients with early-stage (T1/T2) oral squamous cell carcinoma with N0 neck.
