Sivan classification system for diagnosis of jaw lesions based on visual volumetric analysis of 3-dimensional cone-beam computed tomographic images.

A novel classification system, termed the Sivan classification, was developed to enhance the diagnosis of jaw lesions by utilizing visual volumetric analysis of three-dimensional Cone Beam Computed Tomography (CBCT) images. This classification groups lesions into ten categories, primarily divided into hypovolumetric, hypervolumetric, and normovolumetric groups. To validate this system, 10 raters-comprising 5 general dentists and 5 oral radiology specialists-assessed the CBCT images and diagnosed the lesions using the Sivan classification.

Congenital Hemifacial Hyperplasia: Clinical Presentation and Literature Review.

Hemifacial hyperplasia is a rare congenital malformation characterized by noticeable unilateral excess development of hard and soft tissues of the face. Asymmetry in Congenital Hemifacial Hyperplasia (CHH) is usually evident at birth and accentuated at the age of puberty. The affected side grows exponentially as compared to the unaffected side.

Primary squamous cell carcinoma of lung leading to metastatic jaw tumor.

Metastatic tumors to the orofacial region are unusual and they may occur in the oral soft tissues or jaw bones. Owing to their clinical variability the diagnosis of such tumors is often a dilemma. We report a unique case of mandibular metastasis which became the first evidence of an occult primary in the lung.

Evaluation of reliability of ultrasonographic parameters in differentiating benign and metastatic cervical group of lymph nodes.

The aim of the current study is to determine the efficacy of ultrasound in differentiating between benign and metastatic group of cervical lymph nodes. The study included forty-five subjects who were divided into three groups with 15 in each, by stratified random sampling method. Group 1 comprised fifteen patients without signs and symptoms of any infection and neoplasms in head and neck region (control group).
