Objective: Validation and cross-cultural adaptation of the Tonsil and Adenoid Health Status Instrument, in Portuguese. Methods: A prospective study was carried out to evaluate and to compare 51 consecutive patients who underwent tonsillectomy or adenotonsillectomy operation (pre-operative and 6 months post-operative) and 49 asymptomatic controls. Results: The Mann-Whitney test showed a statistically significant difference in the mean score between the patients and the control group denoting good clinical validity. The Cronbach’s coefficient value for the EP-TAHSI for 50 cases was 0.946, demonstrating good internal consistency. The Wilcoxon signed-rank test showed a marked improvement in the patients’ scores 6 months post-operatively. Spearman’s rank and Pearson’s correlations were used to correlate the level of the resemblance of the mean score of the EP-TAHSI, which showed statistically significant results. Conclusions: EP-TAHSI is a valid instrument for evaluating the subjective effect of tonsillectomy on the health and quality of life and hence is recommended to be used in tonsillectomy research and daily practice. It adds value in the follow-up after surgery and in legal issues that can arise in that line.
