Of 770 hypofunctioning thyroid nodules subjected to needle biopsy since 1977, the fluid of 172 cysts (22%) was aspirated. The fluid, cytologically examined, showed no evidence of @entity189 except in three instances: @entity1377 that were subsequently treated surgically. Of the cystic lesions, 19 (11%) recurred and were treated by reaspiration and the instillation of @entity803 into the cyst cavity. In all but one instance this resulted in obliteration of the cysts (95%). This is a considerably higher rate of success than that reported from aspiration alone (40% to 85%). The follow-up period ranged from 1 to 42 months, with no recurrence or subsequent development of a thyroid nodule in these @entity1 . The one recurrent cyst was reaspirated and reinstilled a second time, which resulted in great reduction in size. Not considered for this procedure were @entity1 in whom the cytologic condition of the fluid was abnormal or indicative of a @entity5 . Also excluded were those in whom there was incomplete decompression of the cyst, manifested by a persistent nodule. No @entity1 had a history of @entity135 irradiation or cervical @entity3329 , both contraindications for this procedure. No @entity1 had grossly bloody aspirates. Recurrence of @entity8426 after aspiration was not thought to be, in itself, a criterion for surgical selection. The effective use of @entity803 as a sclerosing agent in the treatment of @entity3483 is well documented. Its action in producing symphysis is thought to be related to its low pH (2.0). This procedure is safe, simple, cost effective, and well tolerated by @entity1 . It obviates the need for excision in @entity1 who fulfill the aforementioned criteria.
