Mandibular Nerve Block for Oral Cavity Examination and Upper Gastroscopy during Trismus Caused by Carcinoma of Tongue
Trismus in oral cancer is defined as a tonic contraction of the muscles of mastication resulting from any abnormal condition or disease with mouth opening of ≤35 mm or as low as 0mm1. Its incidence varies greatly and results in difficulty in activities such as biting, chewing, swallowing and speaking and may further lead to poor oral hygiene, pain, weight loss, depression, difficult for doing medical screening and intervention. Overall it leads to decreased quality of life.
