Objective: To describe the speech and swallowing characteristics following segmental mandibulectomy and coronoidectomy to release trismus. Materials and Methods: A detailed speech and swallowing function assessment was carried out using various formal and informal tests following the surgeries. Result: After the initial assessment, the patient had severe impairment with the movement of articulators, and distortion was observed for labio dentals, lingual sounds, and vowels. Speech intelligibility, diadokokinetic rate, maximum phonation duration were reduced, and also patient had severe voice problem and swallowing problems. Following the assessment post-coronoidectomy, patient had articulatory errors such as distortion, omission, and substitution for majority of sounds secondary to reduced articulatory movements. Swallowing and voice characteristics have improved slightly, and the voice parameters were near normal. Conclusion: Segmental mandibulectomy can have several effects on an individual's daily living as it affects speech, which becomes a major hindrance for communication. Also, due to the swallowing difficulties, there may be health issues. Hence, the affected individuals should be evaluated by a speech language pathologist to define the exact nature of changes in communication (including speech and voice), and swallowing that also helps to plan a comprehensive management strategy that includes speech therapy and surgical recommendation, which will have good prognosis in speech and swallow characteristics to give a good quality of life.
