Human Papillomavirus Detection in Oropharyngeal Squamous Cell Carcinoma Using p16 Immunohistochemistry.

Introduction: Oral cancer ranks third among all cancers in the Indian population with approximately 45% of call cancer cases in India being diagnosed as oral cancer, among which 20%-50% of the cases are observed to be associated with human papillomavirus (HPV) infection.

Aim: This study aims to detect and evaluate the presence of p16 in oropharyngeal squamous cell carcinoma (OPSCC) patients using immunohistochemistry (IHC).

Materials And Methods: This study was based on samples collected from 21 patients with primary OPSCC who were diagnosed and treated during the period of December 2017-March 2018.

Osteomyelitis in the head and neck.

Conclusion: All bones of the facial skeleton and spine are susceptible to osteomyelitis due to various predisposing conditions. Current radiological tools are sufficient to provide adequate diagnosis. Treatment can be conservative resection of the diseased bone with adequate clearance in all cases except in cases of osteomyelitis due to osteoradionecrosis (ORN) where resection has to be more radical.
