title: Video-assisted parathyroidectomy via the lateral approach vs conventional surgery in the treatment of sporadic primary hyperparathyroidism: results of a case-control study.
abstract: BACKGROUND
  We previously demonstrated that minimally invasive video-assisted parathyroidectomy (VAP) can be performed via a lateral approach on the line of the sternocleidomastoid muscle. The aim of this study was to compare the results of this technique with those of conventional parathyroidectomy (CP) in a case-control study.
  
  
  METHODS
  Over a 2-year period, 80 VAP were attempted. The selection criteria were as follows: sporadic primary hyperparathyroidism, no history of previous neck surgery, no thyroid disease, suggestion of a single adenoma on preoperative imaging. A rapid intraoperative parathyroid hormone (PTH) assay was performed. The procedure was completed successfully in 68 patients. A case-control study of 68 patients who underwent CP for a single adenoma was performed. The controls were matched for age and sex.
  
  
  RESULTS
  All of the patients were normocalcemic at follow-up. No statistically significant differences between the VAP and the control groups were found for age, sex, pre- and postoperative calcemia and PTH, adenoma weight, operating time, complication rate, or postoperative stay. One VAP patient developed recurrent laryngeal nerve palsy. Patients who underwent VAP required less analgesics (p < 0.0001) and were more satisfied with the cosmetic results (p < 0.0001).
  
  
  CONCLUSIONS
  This study suggests that VAP by the lateral approach has some advantages over CP in terms of postoperative pain and cosmetic results.
