Objective: to investigated the swallowing changes in these patients receiving mandibular-lip split or pull-through resection surgeries by using the videofluoroscopy (VFSS) and high resolution impedance manometry (HRIM).~Methods: 1. patients are fulfilled elective mandibular-lip split or pull-through resection surgeries; 2. they all received VFSS and HRIM exmination before surgery. 3. they were randomized into two groups (mandibular-lip split surgery or pull-through resection surgeries).~4. after receiving the surgery, the patients were followed the swallowing function at postoperative 1, 3, and 6 months.~Anticipating results: the swallowing function at pull-through resection surgery has faster recovery than mandibular lip split methods.
The evidence of swallowing changes in tongue cancer patients receiving mandibular-lip split or pull-through resection surgeries is still limited. This study aimed to investigated the swallowing changes in these patients by using the videofluoroscopy (VFSS) and high resolution impedance manometry (HRIM).
