| Abstract;Purpose: To estimate the influence of function of the reconstructed tongue on postoperative masticatory function Methods: We assessed postoperative functions in seven tongue cancer patients with reconstruction of the tongue and oral floor, categorized into group A of Eichner's Classification. Masticatory function was evaluated using the low-adhesive color-developing chewing gum method, and was expressed as masticatory performance (a*: chromaticness). Further, the modified questionnaire of Yamamoto's masticatory grade as to diet was used for a subjective evaluation. Occlusal measurements (occlusal platform area and total bite force) were taken with the Occlusal Prescale. As the function of the tongue, voluntary tongue movements were evaluated by four criteria, and two sensory modalities (touch and heat sensation) were evaluated. Results: 1. Masticatory performance in tongue cancer patients with reconstruction was significantly lower than in normals. 2. Yamamoto's masticatory grade (subjective evaluation) did not agree with masticatory performance (objective evaluation). 3. The occlusal platform area or total bite force in these patients bears no definite relation to masticatory performance. 4. Patients with good voluntary tongue movement showed good masticatory function. 5. Patients with good sensory recovery on flap exhibited good masticatory function. Conclusion: Mobility and sensation of the reconstructed tongue are crucial factors for postoperative masticatory function. (author abst.) |
