Tongue Pressure in Patients with Tongue Cancer Resection and Reconstruction

Objective: Assessment of tongue function following tongue reconstruction is important to evaluate patient status. To assess tongue function in patients who had undergone tongue reconstruction, the surgical team used a simple, hand-held tongue pressure measurement device to measure tongue power.

Methods: Tongue power of 30 patients (25 males, 5 females; average age: 53.6±15.0 years) was calculated using a hand-held tongue pressure measurement device, six months postoperation. The defects were classified into minimal glossectomy (MG) (n=8), near-half partial glossectomy of the mobile tongue (PG) (n=5), hemi-glossectomy (HG) (n=4), more than half partial glossectomy of the mobile tongue (SG-MT) (n=7), and subtotal glossectomy (SG) (n=6). As seen in other tongue assessments, a simple articulatory test, food evaluation, and speech intelligibility assessment were also performed; resulting correlations were statistically calculated using tongue pressure values.

Results: The tongue pressure values were 94.0±14.5% in MG, 48.5±13.2(a) % in PG, 40.4±18.7(a) % in HG, 19.3±7.7(a,b) % in SG-MT, and 15.3±5.6(a,b) % in SG (a: <0.05 vs. MG, b: <0.05 vs. PG). The Pearson r was 0.77, 0.67, and 0.74 when correlated with simple articulatory test, food evaluation, and speech intelligibility assessment, respectively.

Conclusion: Tongue pressure measurement in patients with tongue cancer resection and reconstruction facilitated determination of patients' tongue function status.
