%X BACKGROUND: The extent of surgical resection for tongue tumors is determined by tumor size, potentially affecting oral function and quality of life (QoL). However, the relationship between oral dysfunction and QoL decline due to glossectomy extent remains unexplored. Therefore, these correlations and their predictive value for postoperative QoL decline were elucidated.
METHODS: Patients treated for tongue cancer at our hospital between 2018 and 2022 were categorized by partial, hemi, or subtotal/total glossectomy. Assessments included swallowing function (RSST), articulation (Oral Diadochokinesis (ODK)), mastication, tongue pressure, and oral moisture. QoL was measured using the Oral Health Impact Profile-14 (OHIP-14). Differences within parameters were assessed using Kruskal-Wallis tests, and between-group comparisons via Mann-Whitney U tests. Spearman's correlation analysis examined parameter relationship.
RESULTS: 35 patients were evaluated. Significant differences were found in ODK [ta] (p = 0.015), [ka] (p = 0.0006), tongue pressure (p = 0.0001), moisture levels (p = 0.031), OHIP-14 domains: physical disability (p = 0.014) and social disability (p = 0.046). ODK [ta] (PG: 5.95, HG: 5.38, TG: 4.03 times), [ka] (PG: 5.56, HG: 4.78, TG: 3.23 times), and tongue pressure (PG: 32.9, HG: 21.2, TG: 10.3 mmHg) decreased with glossectomy extent, while physical (PG: 0.27, HG: 2.38, TG: 2.00) and social disability (PG: 0.18, HG: 0.94, TG: 1.43) worsened. A significant negative correlation was observed between tongue pressure and social disability (p = 0.013, r = -0.36).
CONCLUSIONS: Expanding resection significantly impacted postoperative oral function and QoL. Tongue pressure assessment may predict long-term social disability in patient QoL.
