Factors Affecting the Swallowing Dysfunction Following Oral Cancer Surgery

Abstract: Objective To investigate the factors affecting the postoperative swallowing dysfunction in patients who underwent oral cancer surgery.Methods Retrospective review of clinical records of 70 patients (50 males and 20 females) who underwent oral cancer surgeries from July 2007 to April 2015 were enrolled. Multiple regression analysis was performed using the Food Intake LEVEL Scale (FILS) at discharge as the objective variable and age, tumor size, resection of the tongue base, suprahyoid muscle resection, segmenta… Show more

“…Resection of over half of the tongue base is associated with poor swallowing outcomes. 19,20 In the present study, only five of the 16 patients in the glossectomy group underwent subtotal glossectomy, and the glossectomy group was not worse than the composite resection group in the swallowing parameters except for the composite MDADI score. The addition of chemotherapy or radiotherapy is associated with significantly increased odds of dysphagia.…”

“…Though the tube feeding rates were higher among patients with T classification 4 disease (21% at 1 month and 20% at 6 months postoperation), these rates are still relatively low compared with a recent study on patients who had undergone surgery for oral cavity cancer, 18 demonstrating the tube feeding rates of 45.8% at 1 month and 22% at 6 months postoperation. Several other factors might also contribute to the relatively low tube feeding rates in the present study: our surgeons took great care to preserve the suprahyoid muscles and uninvolved oropharyngeal structures, including tongue base and related pharyngeal muscles, to minimize the adverse influence on deglutition 19,20,24 ; efforts were also made by our radiation oncologists to reduce radiation dose on the important swallowing-related structures under appropriate therapeutic consideration. 3,25,26 The present study has several limitations.…”

“…The site of the oral cancer may impact functions like breathing, speaking, swallowing, eating, and swallowing and may affect social interactions. The proximity of the tumors in the buccal mucosa and floor of the mouth to important structures may cause a significant disruption in their functions compared to other sites [ 17 ].…”

“…If the tongue is weak or paralyzed, the bolus may spill into the oral cavity or into the pharynx, which can lead to aspiration before swallowing [12]. Also, a previous study has shown that tongue base resection showed significant correlation with swallowing dysfunction who underwent oral cancer surgery [13].…”
