Approximately 130,000 adenoidectomies are performed each year in the United States. Few studies have examined adenoid regrowth and the incidence of revision surgery or have compared four different surgical instruments commonly used for adenoid surgery within the same institution. This study aimed to determine the incidence of revision adenoidectomy after the use of microdebrider, Coblation, suction cautery, and curette instruments over a 10-year period at a single major tertiary children's center in the United States. A retrospective chart review was performed for all patients who underwent primary and/or revision adenoidectomy at the Children's Hospital Los Angeles (CHLA) between August 2004 and August 2014. During the 10-year study period, a microdebrider was used in 212 cases, Coblation in 382, suction cautery in 1,926, and curette in 3,139 adenoidectomies. The percentages of revision adenoidectomy were 1.42% (3 patients) for microdebrider, 0.79% (3 patients) for Coblation, 0.36% (7 patients) for suction cautery, and 0.03% (1 patient) for curette. The cumulative incidence of revision adenoidectomy for initial surgeries performed at CHLA was 0.2% for the 10-year study period. Pearson chi-square analysis showed statistically significant differences between the surgical techniques (p < 0.0001). In conclusion, regrowth of adenoid tissue requiring revision surgery occurs very infrequently irrespective of the instrument used for the primary procedure, and the most common indication for revision adenoidectomy is to improve eustachian tube dysfunction rather than nasal obstruction due to adenoid hypertrophy.
