XXXX after total thyroidectomy: incidence and resolution.

BACKGROUND: @entity461 ( @entity461 ) levels are often measured after thyroid surgery and are used to detect @entity1 at risk for @entity86 . However, there is a lack of consensus in the literature about how to define the recovery of parathyroid gland function and when to classify @entity261 as permanent. The goals of this study were to determine the incidence of low postoperative @entity461 in total thyroidectomy @entity1 and to monitor their time course to recovery of parathyroid gland function. METHODS: We identified 1054 consecutive @entity1 who underwent a total or completion thyroidectomy from January, 2006-December, 2013. Low @entity461 was defined as a @entity461 measurement <10 pg/mL immediately after surgery. @entity1 were considered to be permanently @entity261 if they had not recovered within 1  y. Recovery of parathyroid gland function was defined as @entity461 >= 10 pg/mL and no need for therapeutic @entity460 or activated @entity560 ( @entity3873 ) supplementation to prevent @entity14645 symptoms. RESULTS: Of 1054 total thyroidectomy @entity1 , 189 (18%) had a postoperative @entity461 <10 pg/mL. Of those 189 @entity1 , 132 (70%) showed resolution within 2  mo of surgery. Notably, 9 (5%) resolved between 6 and 12  mo. At 1  y, 20 (1.9%) were considered to have permanent @entity261 . Surprisingly, 50% of those @entity1 had recovery of @entity461 levels yet still required supplementation to avoid symptoms. CONCLUSIONS: Most @entity1 with a low postoperative @entity461 recover function quickly, but it can take up to 1  y for full resolution. @entity261 needs to be defined not only by @entity461 levels but also by medication requirements.
