focused parathyroidectomy
Targeted surgical removal of a single parathyroid adenoma using preoperative localization studies and intraoperative PTH monitoring.
Full Definition
Focused parathyroidectomy is a minimally invasive surgical approach for removing solitary parathyroid adenomas in patients with primary hyperparathyroidism. This technique relies heavily on accurate preoperative localization using sestamibi scanning and ultrasound to identify the abnormal gland. The procedure involves a small, directed incision over the localized adenoma rather than comprehensive four-gland exploration. Intraoperative parathyroid hormone (PTH) monitoring confirms successful removal by demonstrating a greater than 50% decline in PTH levels within 10-15 minutes of gland removal. This approach offers reduced operative time, smaller incisions, and faster recovery compared to traditional bilateral neck exploration.
Usage
Usage note: Emphasize reliance on preoperative imaging and intraoperative PTH monitoring.
In Context
- "Preoperative sestamibi scan localized the adenoma to the right superior position, enabling focused parathyroidectomy through a 2-cm incision." — operative note
- "Intraoperative PTH monitoring during focused parathyroidectomy showed a 75% decline, confirming successful adenoma removal." — operative note
