: This study highlights the impact of tumor location, disease stage, and treatment modalities on the quality of life of oral cancer survivors, assessed using the University of Washington QoL questionnaire and the Performance Status Scale Diet Scale. The findings emphasize the need for personalized rehabilitation strategies, particularly for speech and dietary functions, to enhance post-treatment recovery. Identifying site-specific challenges can aid in developing targeted interventions, improving functional outcomes and patient well-being. The study findings are critical for oncologists, surgeons, and rehabilitation specialists to optimize treatment plans and post-surgical care for oral cancer patients.
