Brunaud L, Zarnegar R, Wada N, Ituarte P, Clark OH, Duh Q. Incision Length for Standard Thyroidectomy and Parathyroidectomy: When Is It Minimally Invasive? Arch Surg. 2003;138(10):1140–1143. doi:10.1001/archsurg.138.10.1140
Current techniques for open conventional thyroidectomy or parathyroidectomy have evolved to enable a shorter incision (main proposition), and the length of the incision is influenced by objective factors.
University referral center.
Patients and Intervention
Retrospective study of the most recent 200 primary consecutive routine thyroid and parathyroid operations (excluding neck dissections).
Main Outcome Measures
The length of incision was routinely measured with a ruler before the incision. Univariate and multivariate analysis was performed to distinguish variables affecting length of incision.
Mean length of the incision was 5.5 cm for total thyroidectomy, 4.6 cm for lobectomy, and 3.5 cm for parathyroidectomy (P<.001). It was 4.1 cm for bilateral parathyroid exploration, but was reduced to 3.2 and 2.8 cm for unilateral (P<.001) and focal (P<.001) explorations, respectively. By multiple regression analysis, thyroid specimen volume and patient body mass index were independent predictors of incision length in thyroidectomy. Extent of exploration and resident training level were independent predictors of incision length in parathyroidectomy.
Current techniques for open conventional thyroidectomy or parathyroidectomy have evolved to enable a shorter incision. Thyroid volume, patient body mass index, extent of the planned parathyroid exploration, and the resident clinical training stage are important variables for incision length in open operation and should be taken into account when minimally invasive thyroidectomy and parathyroidectomy are evaluated.
