title: [Functional results of parathyroid autotransplantation in one single pocket for treatment of secondary hyperparathyroidism].
abstract: OBJECTIVE
  To evaluate the operation and surgical time of autotransplanted parathyroid in a single site comparing it to the implant performed in five and twenty locations.
  
  
  METHODS
  Patients who underwent total parotidectomy with auto implant (Ptx-AI) for secondary and tertiary hyperparathyroidism were evaluated in groups of 20 implant sites (A), 5 sites (B) and single site (C), compared as for Functional Status (FE) of the implant and the surgical time of the procedure. Four functional states were determined according to the systemic level of PTH: 1-below normal, 2-normal, 3-high, no more than three times and 4 - more than three times higher.
  
  
  RESULTS
  There were 349 patients subjected to Ptx-AI for renal hyperparathyroidism from 1994 to 2009. For the functional study, 101 patients were eligible for the following observations: group A (n = 30) - 16.6% EF1, 50% EF2, 23.3% EF3 and 10%EF4; group B (n = 41) - 14.6% EF1, 58.5% EF2, 22% EF3 and 4.9% EF4; Group C (n = 30) - 17% EF1, 57% EF2, 20%EF3 and 6% EF4 (p = 0.9, x²). But in group C the mean operative time of implant was statistically lower (7.9 minutes) compared to the average of 5 site (18.6 minutes) and 20-site (44 minutes) implants in 66 evaluated patients (p<0,0001, ANOVA).
  
  
  CONCLUSIONS
  The self-implantation in a single site decreases the operative time without changing its functionality.
