Efficacy of adenoidectomy in recurrent otitis media. Historical overview and preliminary results from a randomized,
Insights
Adenoidectomy for otitis media lacks conclusive evidence. Current research, including a randomized trial, is ongoing but preliminary data suggest it does not fully resolve the condition in children.
Area of Science:
- Otolaryngology
- Pediatric Medicine
- Clinical Trials
Background:
- Adenoidectomy is frequently performed for pediatric otitis media.
- Concomitant tonsillectomy is often done, but its necessity is debated.
- Existing evidence for adenoidectomy's efficacy in otitis media is limited and contradictory.
Purpose of the Study:
- To evaluate the effectiveness of adenoidectomy in treating children with otitis media.
- To address the uncertainty surrounding adenoidectomy and tonsillectomy and adenoidectomy (T&A) efficacy.
Main Methods:
- A prospective, randomized, controlled clinical trial involving high-risk children.
- Inclusion of subject variables (age, sex, adenoid size, allergy) and treatment variables (myringotomy with tympanostomy tubes).
- Outcome measures include acute otitis media episodes, middle ear effusion persistence, and re-myringotomy frequency.
Main Results:
- Data are currently insufficient to definitively conclude on adenoidectomy's efficacy.
- Preliminary findings indicate that adenoidectomy does not completely eliminate otitis media issues.
Conclusions:
- The efficacy of adenoidectomy, alone or with tonsillectomy, for otitis media remains uncertain.
- Further data from the ongoing clinical trial are required for definitive conclusions.
Abstract:
Adenoidectomy is well established as a procedure for treating children with recurrent or persistent otitis media. Many physicians also believe that when adenoidectomy is undertaken for otitis media, tonsillectomy also should be done routinely. Thus otitis media serves as the justification for a substantial proportion of the tonsil and adenoid operations carried out on children. Nonetheless, evidence supporting the efficacy of adenoidectomy, or tonsillectomy and adenoidectomy (T&A), for otitis media is scant and inconclusive. Only six prospective studies have been reported, and in all but two of them, the combination of adenoidectomy with tonsillectomy, rather than adenoidectomy alone, was tested. The results were contradictory, perhaps because of all the studies contained flaws in design or methodology or both. Whether adenoidectomy or T&A are efficacious remains entirely uncertain. We are attempting to address the question currently in a prospective study in which children considered at high risk for otitis media are entered into a randomized, controlled clinical trial of adenoidectomy. The trial is complicated by the need to take adequate account of subject variables such as age, sex, adenoid size, and the presence or absence of allergy, and of the important treatment variables of concomitant myringotomy with tympanostomy tube insertion. Outcome measurements employed in the trial include the number of episodes per year of acute otitis media, the persistence of middle ear effusion, and the frequency of subsequent myringotomy. Data thus far collected in the study are not sufficient to reach a conclusion for or against the efficacy of adenoidectomy for otitis media, but it is apparent that adenoidectomy by no means eliminates the problem.
