OBJECTIVES: To review surgical techniques used in the treatment of laryngoceles over the last two decades and point out developments and trends. MATERIALS AND METHODS: PubMed, the Cochrane Library, and the JBI Library of Systematic Reviews were searched using the term "laryngocele." Demographic data, type of laryngocele, presence of a laryngopyocele, type of treatment and need for a tracheotomy were assessed. RESULTS: Overall, data on 86 patients were analyzed, culled from 50 articles, of which 41 were case reports and 9 were case series. No single systematic review or meta-analysis or randomized controlled trial has been published on the topic. Altogether, 71 laryngoceles in 63 patients met the criteria for further analysis focusing on surgical treatment. An external approach was selected in 25/29 (86.2%) cases of combined laryngoceles. Microlaryngoscopic resection using a CO2 laser was performed in three cases and endoscopic robotic surgery in one case. The majority of patients with an internal laryngocele, 31/42 (73.8%), were treated using the microlaryngoscopy approach. CONCLUSIONS: Microlaryngoscopy involving the use of a CO2 laser has become the main therapeutic procedure for the treatment of internal laryngoceles during the past 20 years. An external approach still remains the main therapeutic approach for the treatment of combined laryngoceles.
