Improvement in Tongue Movement, Ingestion, and Speech by a Jaw Denture after the Treatment of Squamous Cell Carcinoma in the Mouth Floor

Abstract

Patients: A 63-year-old male at the first examination. The patient was diagnosed as having squamous cell carcinoma in the mouth floor (T4N2cM0), and received tumor excision surgery, functional dissection in the bilateral cervical regions, and left antebrachial skin flap transplantation. Thereafter, the patient was referred to our department requesting improvement in ingestion, swallowing, and speech. After examination, a mandibular denture and maxillary PAP were inserted. Thereafter, ingestion, swallowing, and speech training was performed.
Discussion: We judged that adjustment of prosthetic appliances after insertion, ingestion and swallowing instruction, and speech training should be performed in cooperation with the department of oral surgery.
Conclusion: After the treatment of squamous cell carcinoma in the mouth floor, prosthetic appliances were inserted, and improvement in ingestion and swallowing disorders was noted after chewing, swallowing, and speech functional training and instruction, showing a good clinical course.
