Objective: The objective of this study was to assess the risk of recurrence of ovarian mature cystic teratoma (OMCT) and to evaluate the feasibility of ovarian-conserving surgery.Methods: This retrospective clinical study investigated patients with OMCT who underwent laparoscopic surgery between January 2014 and March 2017.Results: Recurrence of OMCT was observed in 7 of 81 patients (8.6 %)—three patients (3.7%) showed ipsilateral recurrence, and four patients (4.9 %) showed recurrence in the contralateral ovary. Patients with recurrence (mean age 22.5 years [range 15–30 years]) were younger than those without recurrence (mean age 33.5 years [range 16–63 years]). No significant intergroup differences were observed in gravidity, parity, cyst size, intraoperative cyst rupture (cysts that did or did not rupture), number of cysts, and laterality. Conclusion: The recurrence tendency of OMCT in adolescents and in patients in their early 20s was higher than that in older patients. Cystectomy should be considered in children and patients of reproductive age for conservation of the affected ovary. An initial adnexectomy may not obviate the risk of multiple subsequent surgeries because OMCT may recur in the contralateral ovary.
