Abstract
OBJECTIVE: To perform a systematic review with meta-analysis of data to determine the rates of repeat surgery and supraglottic stenosis in unilateral versus bilateral supraglottoplasty for laryngomalacia. DATA SOURCES: PubMed/Medline, Cochrane Central, Scopus, Google Scholar, Web of Science, and Embase. REVIEW METHODS: Databases were searched through January 30, 2018. Studies with unilateral or bilateral supraglottoplasty techniques for laryngomalacia were included. The need for repeat (revision or completion) surgery and rates of supraglottic stenosis were primary outcomes. Data were substratified and a meta-analysis performed. RESULTS: A total of 251 articles were reviewed, and 20 articles met inclusion criteria (1186 patients: 663 bilateral, 523 unilateral). Regarding the need to return to surgery, the rate of revision for bilateral surgery was 4.1%, compared to the revision and combined revision/completion rates for unilateral surgery which respectively were 1.1% (odds ratio [OR] 0.27; 95% CI 0.11-0.67; P = .002) and 18.0% (OR 5.16; 95% CI 3.31-8.06; P < .0001). The unilateral versus bilateral supraglottic stenosis rates were 0% versus 1.2% (P = .011). CONCLUSION: Unilateral supraglottoplasty has a significantly higher rate of repeat surgery, mainly attributed to contralateral surgery, when compared with bilateral supraglottoplasty. There is a small but statistically significant risk of supraglottic stenosis in bilateral procedures. The benefit of a unilateral procedure should be weighed against the cost of subjecting patients to a 4-fold increased risk of repeat surgery.
