摘要

Aims

This study assessed perioperative changes in tongue pressure (TP) following tonsillectomy as an indicator of swallowing function and examined its association with patient-specific factors.

Materials and Methods

A prospective, observational study was conducted on 39 patients (20–80 years) undergoing bilateral tonsillectomy. TP and pain levels using the numerical rating scale (NRS) were measured at five time points: preoperative (Day 0), postoperative Day 1 (POD 1), Day 4 (POD 4), Week 2 (POW 2), and Week 4 (POW 4). Preoperative body mass index (BMI) and Brodsky tonsil grading scale were recorded. Statistical analyses included repeated-measures ANOVA, Kruskal–Wallis tests, and multiple regression.

Results

TP decreased on POD 1 compared to preoperative levels (mean 41.0 to 34.6 kPa) but improved significantly by POW 2 and POW 4 (p < 0.01), surpassing preoperative values by POW 4 (mean 47.1 kPa). NRS scores peaked on POD 1 (average 4.67) and decreased significantly by POW 4 (average 0.08, p < 0.01). Multiple regression identified age (p = 0.01) and BMI (p < 0.01) as significant predictors of preoperative TP, but tonsil size showed no significant association.

Conclusion

Tonsillectomy temporarily reduced TP but ultimately resulted in a slight increase by POW 4, indicating improved swallowing function. The consistent improvement in TP values with pain reduction highlights the importance of adequate pain management. Preoperative TP was significantly associated with age and BMI but not with palatine tonsil size. These findings provide insights into the physiological effects of tonsillectomy on swallowing function and perioperative management.
