Johnston J, et al. - This retrospective cohort study was formulated in order to gauge the incidence and factors associated with revision adenoidectomy. The following factors were disclosed to be related to revision adenoidectomy: Females; patients who were prescribed more than five courses of antibiotics prior to initial adenoidectomy; patients with a diagnosis of otitis media with effusion; a diagnosis of asthma, gastroesophageal reflux disease, and allergic rhinitis; an age of over 4 years at the time of initial adenoidectomy and adenoids that obstructed over 75% of the nasal choanae.

Methods

• Data was extracted with regard to the all hospital morbidity records belonging to patients under the age of 18 years, who underwent one or more adenoidectomy procedures (with or without tonsillectomy) between January 1, 2000 and June 2016 at a tertiary care children's hospital.
• Data analysis comprised of demographic, diagnostic, and procedural data.
• Community prescribing information was scrutinized for the number of courses of antibiotics prescribed to each patient before initial adenoidectomy.

Results

• This study was conducted on 8,260 patients under the age of 18 years who underwent primary adenoidectomy from 2000 to 2016 at a tertiary pediatric hospital.
• Herein, 2.5% (n = 212) of patients underwent revision adenoidectomy, during the same time period.
• In comparison with the male counterparts, a higher proportion of females underwent revision adenoidectomy (p=0.007).
• Those recieving more than five courses of antibiotics prior to initial adenoidectomy exhibited a greater tendency to undergo revision adenoidectomy (p=0.003).
• Patients with a diagnosis of otitis media with effusion illustrated a greater likelihood of undergoing revision adenoidectomy (p =< 0.001). A diagnosis of asthma (p =< 0.001), gastroesophageal reflux disease (GERD) (p =< 0.001), and allergic rhinitis (p =< 0.001) correlated with revision adenoidectomy.
• The data shed light on the connection between an age of over 4 years at the time of initial adenoidectomy with revision adenoidectomy (p =< 0.001).
• A tie-up was noted between adenoids that obstructed over 75% of the nasal choanae with revision adenoidectomy in the study cohort (p =< 0.001).
