ObjectiveThe objective of this study is to review the published literature on supraglottoplasty techniques for correcting laryngomalacia, and to subsequently provide a standardized classification system.MethodsThree authors independently and systematically searched Pubmed/MEDLINE and six additional databases for all studies that included descriptions of supraglottoplasty techniques for correcting laryngomalacia. Sub-sites operated on and specific technique descriptions were reviewed, cataloged and subsequently categorized. This data was then used to develop a new classification system.Results231 articles were identified, downloaded and reviewed in full text. 53 articles with 1669 patients from the included articles described in detail the supraglottoplasty procedure. 84 articles with 5731 patients had to be excluded secondary to not providing detail about the supraglottoplasty procedure. The resultant data identifies the need for a more standardized reporting of the supraglottoplasty procedure in order to more accurately evaluate technique specific outcomes. Currently 77% of the patients in the literature cannot be assessed for outcomes as they did not describe the details for the procedures. Eight variations of supraglottoplasty and four variations of epiglottis surgery were described. Based on the literature, we consolidated the surgery into the following types: Type 1: Debulking of arytenoids, Type 2: Division of aryepiglottic folds, Type 3: Epiglottis surgery.ConclusionThis descriptive review identified 53 articles with 1669 patients from the included articles detailing multiple variations of supraglottoplasty techniques. The new classification supplements a previously established system describing laryngomalacia, and simplifies the supraglottoplasty into three descriptive and logical types of categories. Our classification system would give surgeons a universal language to describe the supraglottoplasty performed, which could improve reporting of techniques, and facilitate future communication and research.
