Abstract

BACKGROUND AND OBJECTIVES
Controversy remains regarding whether the age at which patients undergo adenoidectomy is increasing or decreasing. Thus, the aim of this study was to analyze patient age at adenoidectomy over the past 30 years.
SUBJECTS AND METHOD
Retrospective analysis of adenoidectomy patients treated between 1984 and 2013 who were confirmed to have adenoid hypertrophy on physical examination and radiologic findings was performed. Patients were divided into three groups by decade, the 1980s, 1990s, and 2000s. The numbers of patients, mean/median age, maximum age, and sex ratio were analyzed for each group.
RESULTS
A total of 2,450 patients were enrolled, including 466 cases in the 1980s, 946 in the 1990s, and 1,038 in the 2000s. The mean age of patients was 7.38 years in the 1980s, 8.16 in the 1990s, and 8.37 in the 2000s and has significantly increased since the 1990s (p<0.05).
CONCLUSION
The mean age of patients who underwent adenoidectomy has increased over the past 30 years. Therefore, adenoid hypertrophy needs to be considered in children of all ages who visit otorhinolaryngologic departments.

  Fig. 1. The change of mean age during 30 years. The mean age for the 1980s, the 1990s, and the 2000s groups was 7.38, 8.16, and 8.35 years old, respectively. The 1990s and 2000s groups showed a significant increase in mean age ( p＜0.001) com-pared to the 1980s group, but there was no significant difference between the 1990s and the 2000s groups ( p=0.432).

  Fig. 2. The change of the highest age during 30 years. The highest age for the 1980s, the 1990s, and the 2000s groups was 18.92, 21.08, and 21.42 years old, respectively. There was the tendency to increase in highest age in each group during 30 years.

• 

  Fig. 3. The change of chief complaint during 30 years. The main chief complaint for the 1980s was snoring or sleep apnea. There was the tendency to decrease the ratio of snoring or sleep apnea in chief complaint during 30 years. On the other hand, the ratio of nasal obstruction or mouth breathing in chief complaint increased after 1990s.
