Background: In this study, we aimed to evaluate demographic characteristics, preoperative adenoma localization, surgical techniques selected according to the size and localization of adenoma, and clinical results of patients undergoing mediastinal parathyroid adenoma excision.

Methods: Medical records of a total of 11 patients (4 males, 7 females; mean age 52.6 years; range, 25 to 65 years) who underwent excision of mediastinal parathyroid adenoma in our clinic between January 2011 and June 2019 were retrospectively reviewed. Data including demographic characteristics, complaints, preoperative serum calcium, phosphorus, and parathyroid hormone levels, preoperative imaging methods, surgical method, localization and size of adenoma, length of hospital stay, and duration and amount of drainage were recorded.

Results: Adenoma was localized in anterior mediastinum in seven patients and in the middle mediastinum in four patients. The mean diameter calculated by taking into account the longest diameter of parathyroid adenoma was 21.1 mm. The mean drainage duration was 3.5 days in two patients undergoing median sternotomy, five days in one patient undergoing thoracotomy, 1.2 days in three patients undergoing video-assisted thoracoscopic surgery, and 0.6 days in five patients undergoing robotic surgery.

Conclusion: Minimally invasive approaches such as videoassisted thoracoscopic surgery and robotic-assisted surgery are safe and effective approaches for excision of mediastinal parathyroid adenoma.
