Abstract Abstract In Brief In Brief Favorites PDF Get Content & Permissions Abstract: In Brief: Avoidance of recurrent or superior laryngeal nerve injury and maintenance of normal laryngeal physiology and vocal function are key goals for patients undergoing minimally invasive parathyroidectomy (MIP) due to primary hyperparathyroidism. MIP can be performed with exquisite disease control and without significant effects on laryngeal physiology or voice acoustic measures. For the first time, both physiologic and acoustic data support the use of MIP.
