Articulation in postoperative patients treated for early- and advanced-stage tongue cancer

Tongue cancer is among the most prevalent head and neck cancers and is most commonly treated via surgery. We assessed the articulation differences in patients with early and advanced tongue cancer. The study included 26 postoperative tongue cancer patients. We evaluated articulation based on bilabial, labiodental, apical, posterior, laminal, apical front, and apical back speech sounds. The 26 postoperative tongue cancer patients (24 males, two females) had an average age of 54.3 (range 37–89 old) years. Twelve patients were classified as early T stage (T1/T2), while 14 were classified as advanced T stage (T3/T4). The total articulation score was not significantly related to the T stage but apical sounds were so associated. The total articulation score did not significantly differ between postoperative patients with early and advanced tongue cancer. In subgroup analysis, the apical sound was significantly impaired in postoperative patients with advanced tongue cancer.
