App-Assisted Swallowing Program After Oral Cancer Surgery

This study aims to examine the effects of a swallowing care program combined with an exercise mobile application (App) on swallowing function, anxiety, and quality of life in patients with oral cancer after flap reconstruction surgery. The goal is to determine whether integrating App-based swallowing exercises into postoperative care can improve rehabilitation outcomes compared with conventional care alone. A purposive sampling method will be used to recruit 72 participants from the surgical wards of a medical center in northern Taiwan. Eligible patients scheduled for oral cancer tumor resection and flap reconstruction will be identified through consultation with plastic surgeons. After screening and informed consent, participants will be assigned to a control group or an experimental group, with approximately 36 patients in each group. The control group will receive routine ward education and standard postoperative nursing care, while the experimental group will receive the same care plus an additional intervention using a swallowing exercise App. The intervention will begin on postoperative day 7, guided by the researcher. Follow-up assessments will be conducted during outpatient visits at postoperative week 4 and week 12. To minimize potential interference between participants, data collection will be performed sequentially-first for the control group, followed by the experimental group. Data will be collected through self-administered questionnaires or researcher-assisted interviews, including a demographic survey, the Postoperative Oral Dysfunction-10 (POD-10), the Functional Oral Intake Scale (FOIS), a Visual Analog Scale for Anxiety, and the EORTC QLQ-H\&N35 questionnaire for quality of life. Each assessment will take approximately 20-30 minutes. Participants may withdraw from the study at any time without penalty. Descriptive statistics will be used to summarize participant characteristics. The chi-square test and independent t-test will be used to exami
