[Surgical treatment of differentiated thyroid gland carcinoma. Technique and morbidity in paratracheal lymph node excision].
BACKGROUND
The extent of cervical lymphadenectomy in treatment of differentiated thyroid cancer is controversial. Technique and results of paratracheal lymphadenectomy are presented to demonstrate safety of cervical lymphadenectomy procedures.


METHODS
68 Patients with differentiated thyroid cancer underwent total thyroidectomy and extended lymphadenectomy in a standardized technique. The pre- and paratracheal and the lateral lymph node compartments were cleared.


RESULTS
Permanent pareses of recurrent laryngeal nerve or permanent hypocalcaemias were not observed. 3 patients developed transient recurrent nerve palsy, 26 patients transient hypocalcaemia (Ca2+ > 1.7 and < 2.2 mmol/l). In 3 patients mild voice disturbances, probably due to superior laryngeal nerve dysfunction were observed. In 1 patient short-time tracheotomy was performed. 1 patients showed permanent Horner's syndrome.


CONCLUSIONS
Thyroidectomy with extended lymphadenectomy achieves removal of all cervical tumor masses without relevant morbidity. The distribution of metastatic lymph nodes underlines the necessity of extended lymphadenectomy.
