Endoscopic transoral parathyroidectomy: Initial experience.

Background We evaluate our initial experience of transoral vestibular approach parathyroidectomy (TOEPVA) for the treatment of primary hyperparathyroidism. Methods We conducted a prospective study of patients with single parathyroid adenoma, using TOEPVA to perform the parathyroidectomy. The variables we analyzed were size, volume, and location of the adenoma, bleeding, identification, and preservation of the recurrent laryngeal nerve, injury to the mental nerve, and the effective cure rate, using measures of central tendency. Results Our study included 21 women, with an average age of 43 years. The recurrent laryngeal nerve and mental nerve suffered no permanent damage, the average size of the adenoma was 26.6 mm, and a volume of 3.95 mL. We were able to identify the adenoma and cure the hyperparathyroidism in 20 of the patients (95.2%). Conclusions TOEPVA is viable and safe in who wish to avoid the cervical scar resulting for the patient with primary hyperparathyroidism.
