Parathyroidectomy is a surgical procedure used to correct hyperparathyroidism and parathyroid tumors. Parathyroidectomy is one of a few treatments for parathyroid conditions. Alcohol or heat treatment and dietary changes are conservative treatments for select cases of hyperparathyroidism. Ultrasound-guided ethanol ablation is another treatment for removing parathyroid tumors, but also requires general anesthesia. Because surgery is considered the most invasive procedure for parathyroid conditions, conservative treatments may be utilized first. If alcohol or heat treatments have been unsuccessful, surgery is usually recommended.

The prognosis may vary depending on the severity of the condition. However, parathyroidectomy is usually very effective in treating parathyroid conditions. Parathyroidectomy can be curative for many cases. Other treatments for hyperparathyroidism may damage surrounding glands or organs; surgery has the greatest chance of ensuring such damage does not occur. Complications are possible following surgery, but are usually temporary and easy to correct.

Cats are usually given analgesics to manage pain following surgery. Cats may also be required to take calcium and/or vitamin D supplements. Owners should ensure cats that have undergone parathyroidectomy get plenty of rest and do not engage in activity. Owners should also check the surgery site each day to make sure no swelling, bleeding, or pus has developed. Veterinarians will schedule a follow-up appointment one week following surgery to monitor healing and ensure no complications have arisen.

The cost of parathyroidectomy may vary depending on additional costs incurred, including medications and supportive care. On average, the cost of parathyroidectomy ranges from $500 to $1,500.

Although most parathyroidectomies are successful and do not present complications, postoperative complications are possible. Surgery may cause the remaining parathyroid glands to malfunction due to the absence of one or more of the parathyroid gland(s). This issue usually resolves by itself within a few days following surgery. The most common complication is a low calcium level in the blood, although this is more common in cats that have high calcium levels before surgery. Signs of a low calcium level include:
Owners should consult their veterinarian immediately if they notice any of these signs following surgery. Low calcium levels can be fatal if left untreated. Medication can correct low calcium levels.

Primary hyperparathyroidism is difficult to prevent because it is usually a spontaneous condition. Secondary hyperparathyroidism may be prevented by ensuring cats are fed a complete diet.
