This study aimed to review and critically appraise the available literature concerning marsupialization's effectiveness in reducing cystic jaw lesions in children. The study conducted a search strategy that involved combining the following keywords: (1) children, (2) marsupialization, (3) jaw, and (4) cyst. An electronic search on four critical databases—PubMed, The Cochrane Library, Science Direct, and ResearchGate—to review English‐language articles with no limitations in terms of time, sample size, or type of study design has been conducted. Based on the inclusion and exclusion criteria applied to the preliminary search, 46 studies were included in the final review. Among the 194 identified lesions, the majority were dentigerous cysts (93.8%), followed by radicular cysts (2.6%), odontogenic keratocysts (1.6%), juvenile paradental cysts (1%), and calcifying odontogenic cysts (1%). Postoperatively, permanent teeth involved in the cysts were reported to develop continuously in 40 studies, whereas bone neo‐formation after removal of cystic lesions was reported in 30 studies. Only one study reported postoperative recurrence. The complete healing time of the cysts after marsupialization ranged from 6 months to 5 years. Marsupialization was mainly considered a definite treatment. Because of the long follow‐up period, the cooperation of the patient and family plays an essential role in the success of treatment.
