Parathyroidectomy (Thyroid Intact)
| Available in: Rats and Mice | Anesthetics | Analgesic |
| Pre-Operative Procedures | Intra-Operative Care | Post-Operative Care |
Surgical Preparation
The animal is anesthetized. Sterile eye lubricant is placed in both eyes, and the throat is surgically prepared. The animal is placed in dorsal recumbency on a surgery board fitted with a sterile board drape. Analgesic is administered.
Surgical Description
To expose the parathyroid glands, a small, midline incision is made to the skin just posterior to the chin papilla. Blunt dissection is used to separate the sternohyoideus muscle and the muscle is retracted. The parathyroid glands are located in the upper, outer corners of the thyroid lobes. The circothyroid muscle is lifted away from the thyroid lobes to reveal the parathyroid glands that lie just outside a globular piece of adipose tissue located near the right and left lobes. The parathyroid glands are removed. Bleeding is controlled with sterile, cotton-tipped applicators.
Surgical Closing
The incisions along the throat are closed with approved closing materials (suture or stainless steel clips), and the surgery sites are treated with an approved disinfectant followed by an alcohol swabbing.
Sham
A standard sham parathyroidectomy model is prepared as described above with regards to surgical site preparation, dissection of the throat, exposure of the parathyroid glands, closing, and surgical site disinfection; however, no tissue is removed.
