title: Lingual thyroid: iodine 131: a viable treatment modality revisited.
abstract: OBJECTIVE
  Lingual thyroid has a reported incidence between 1:10 and 1:100,000. When symptomatic, patients may present with dysphagia, choking, and/or dyspnea. Current surgical treatment options range from tumor extirpation or transposition to excision and reimplantation. Tracheotomies are often performed postoperatively for reliable airway control. Iodine 131 (131I) has not been a popular modality of treatment for lingual thyroid because of theoretical fears of increased airway obstruction from thyroiditis. We believe that these fears were not substantiated, and that symptomatic patients needed a reliable, nonsurgical treatment option. Therefore, our goal was to further investigate the use of 131I for the treatment of symptomatic lingual thyroid.
  
  
  METHODS
  A 6-year retrospective chart review was performed. From 1994 to 2000, 2 patients with symptomatic lingual thyroid presented to the Arkansas Cancer Research Center Head and Neck Oncology clinic, University of Arkansas for Medical Sciences, Little Rock, AR. Patients underwent pretreatment computed tomography, and iodine 123 scans. They then received 1 oral dose of 131I. Doses ranged from 30 to 85 mCi. Patients were then followed daily for signs of airway compromise.
  
  
  RESULTS
  Complete resolution of symptoms was seen 2 months after treatment. Patients did not complain of any increased airway compromise during treatment initiation. Patients remain symptom-free and are maintained on thyroid hormone replacement.
  
  
  CONCLUSIONS
  Iodine 131 ablation of lingual thyroid is a safe and effective treatment in symptomatic patients and should be included in the algorithm when formulating a treatment plan.
