Objectives:
To systematically review the current literature on treatment of third and fourth branchial pouch sinuses with endoscopic cauterization, including chemocauterization and electrocauterization, in comparison to surgical treatment.
Data Sources:
PubMed, Embase, and the Cochrane Library.
Review Methods:
We conducted a systematic search. Studies reporting original study data were included. After assessing the directness of evidence and risk of bias, studies with a low directness of evidence or a high risk of bias were excluded from analysis. Cumulative success rates after initial and recurrent treatments were calculated for both methods. A meta-analysis was conducted comparing the success rate of electrocauterization and surgery.
Results:
A total of 2,263 articles were retrieved, of which seven retrospective and one prospective article were eligible for analysis. The cumulative success rate after primary treatment with cauterization ranged from 66.7% to 100%, and ranged from 77.8% to 100% after a second cauterization. The cumulative success rate after the first surgical treatment ranged from 50% to 100% and was 100% after the second surgical attempt. Meta-analysis on electrocauterization showed a nonsignificant risk ratio of 1.35 (95% confidence interval: 0.78-2.33).
Conclusions:
The effectiveness of cauterization in preventing recurrence seems to be comparable to surgical treatment. However, we suggest endoscopic cauterization as the treatment of choice for third and fourth branchial pouch sinuses because of the lower morbidity rate.
