Retrieved data included signalment, physical, clinical, and ultrasonographic examination findings, surgical technique, complications, and outcome. A minimum of 6 months follow\u2010up was obtained.<\/jats:p><jats:p><jats:bold>Results\u2014<\/jats:bold>Six horses were identified. Three horses had tracheal compression and 2 of these also had exercise intolerance. On ultrasonography (5 horses), the enlarged thyroid ranged from 125 to 990 cm<jats:sup>3<\/jats:sup>, and had either a heterogeneous (1 horse), cystic (2), or homogeneous (2) appearance. En bloc, unilateral thyroidectomy under general anesthesia was performed in all horses. After surgery, 3 horses had ipsilateral laryngeal hemiplegia, but tracheal compression was resolved. Thyroid masses were adenoma (3), C\u2010cell compact carcinoma (1), and adenocarcinoma (1). No tumor recurrence or metastatic disease was reported 6 to 14 months after surgery.<\/jats:p><jats:p><jats:bold>Conclusions\u2014<\/jats:bold>Unilateral thyroidectomy can be successfully performed in horses with large thyroid tumors, but laryngeal hemiplegia can be an important surgical complication. Ultrasonographic examination is useful to define thyroid enlargement and location but is seemingly not useful to characterize tumor type.<\/jats:p><jats:p><jats:bold>Clinical Relevance\u2014<\/jats:bold>Thyroidectomy is an uncommon surgical procedure and has an attendant risk for recurrent laryngeal nerve damage. Laryngoscopic examination before and after surgery and careful isolation of the recurrent laryngeal nerve during surgery is recommended.<\/jats:p>","DOI":"10.1053\/jvet.2003.50017","type":"journal-article","created":{"date-parts":[[2003,3,28]],"date-time":"2003-03-28T17:51:26Z","timestamp":1048873886000},"page":"187-190","source":"Crossref","is-referenced-by-count":27,"title":["Unilateral
