Head and neck cancer usually refers to malignant tumours that arise in the mucosa of the oral cavity, pharynx, larynx, nasal cavity, and paranasal sinuses. Pain is a significant problem with head and neck cancers. One study reported an overall pain prevalence of greater than 50% in patients with all cancer types; the highest cancer subtype was head and neck cancer, with a pain prevalence of 70%. Pain may be caused by the cancer itself. Pain can also be caused by cancer invading nerve, muscle, mucosal damage, and tumour pressure. Treatments for cancer like surgery, radiotherapy, and chemotherapy by themselves can also cause pain. One of the commonest manifestations is mucositis-related pain. At times, the pain may be unrelated to cancer and may be myofascial or related to temporomandibular joint dysfunction. Interventional treatments for pain in trigeminal nerve distribution are described in this chapter.
