Aim: Although the standard treatment of ovarian mature teratoma (OMT) is oophorectomy, it can involve
both ovaries with an incidence of 10-20%, both synchronously and metachronously. We aimed to describe
our experience with ovarian sparing surgery (OSS) for OT regarding its effectiveness and reliability in children.
Methods: This is a single-center study that was designed and retrospectively performed on girls under 18
years of age who underwent OSS for OMT between January 2017 to December 2021. The patients who were
diagnosed with unilateral or bilateral OT were included in the study. OSS was performed in patients who had
radiological imaging revealing mature cystic teratoma with fat and calcification content, and normal tumor
marker levels.
Results: We evaluated 15 patients, including 14 unilateral and 1 bilateral synchronous OMT. The mean age
was 13.1 years (4-17). OT was localized on the right ovary in 11 (73.3%) patients, on the left ovary in 3 patients,
and bilateral in 1 patient. The main presenting symptoms were abdominal distension (n=7, 46.6%)
and abdominal pain (n=4, 26.6). Although emergency surgery was required in 3 patients (20%), OSS could be
performed in all cases with an average size of 10.2 cm between 3 and 28 cm. We had seen no complications
related to the surgical option. The mean follow-up was 19 months (5-62 months). The follow-up was done
with ultrasonographic examinations. In the follow-up, it was determined that there were follicles in all preserved
ovaries and there was no recurrence.
Conclusion: To our opinion, OSS is a reliable method for OMT with high effectiveness in keeping the ovarian
reserve and being away from complications. We could perform OSS even whether it was accompanied by
torsion or a big-sized lesion. There was no recurrence in the follow-up period.
