Hypothyroidism and wound healing: occurrence after head and neck radiation and surgery.
A retrospective five-year review of patients treated for cancer of the larynx disclosed a high prevalence of hypothyroidism after combined therapy. A total of 29 patients were studied. Seven (24%) of the 29 patients had hypothyroidism develop in the posttreatment period (zero to two years). Two (22%) of the nine patients treated with a combination of surgery and radiation had hypothyroidism develop. An additional ten patients treated with radiation alone remained clinically euthyroid, and no thyroid function tests were performed. Of the five patients who became hypothyroid after treatment with a combination of surgery and radiation, two had fistulae develop that were resistant to intensive local care. They closed promptly after treatment of the hypothyroidism. Of the two patients who had hypothyroidism develop after surgery alone, one had fistulae develop that were resistant to local cae, but responsive to thyroid hormone. These patients should have thyroid function tests done in the early postoperative period, and those found to be hypothyroid should be treated promptly.
