A Rare Occurrence of Phantom Tongue Pain.

This is a case of phantom tongue pain observed in a 65-year-old male with a history of adenoid cystic carcinoma with involvement of the base of the tongue and supraglottic laryngopharyngeal cancer who underwent a laryngopharyngectomy and glossectomy for treatment. The patient subsequently developed phantom tongue pain in acute rehabilitation. Post total glossectomy phantom pain is rare, and as this is a singular appendage, current techniques that rely on the presence of an intact limb, such as mirror therapy could not be applied to our patient. Therefore mental imagery techniques originally developed for extremity amputation required adaptation to the context of total glossectomy. Recommended anticonvulsant medications, desensitization, and mental imagery techniques for phantom limb pain were effective in relieving the patient's phantom tongue pain. Utilizing therapeutic desensitization techniques may allow for the direction of neuroplasticity in order to decrease pain.
