[The value of intraoperative neuromonitoring in thyroid surgery--a prospective observational study with 926 patients].
The data obtained from 926 patients who, between 01.01.1998 and 31.12.2000, underwent thyroid gland surgery involving the use of neuromonitoring (NM) were recorded prospectively. Every patient was submitted to a preoperative and postoperative laryngoscopic examination by an ENT specialist unrelated to the department. Immediately following surgery, 58 patients were diagnosed as having unilateral or bilateral laryngeal nerve palsy. All of these patients were subsequently followed up by an ENT specialist on an outpatient basis, and 68.3 % (n = 41) of the laryngeal nerve palsies detected immediately after surgery were seen to have resolved. For first operations for benign goitre, a side-related nerve palsy rate ("nerve at risk") of 0.51 % was found. For recurrence surgery, this rate increased to 6.6 %, and for surgery of malignant lesions it was 4.8 %. The conclusion is drawn that in first operations for benign goitre, NM can be employed when and as dictated by the intraoperative findings. In the case of surgery for recurrences or malignant disease, however, intraoperative NM should be applied on a routine basis.
