[Desmoid tumors of the head and neck].

Desmoid tumors of the head and neck, also known as aggressive fibromatoses, are rare. They are soft tissue neoplasms arising from musculoaponeurotic structures and characterized of locally aggressive infiltration and recurrences. Complete surgical excision of desmoid tumors is considered to be the only effective method of cure. It is likewise important to make a function-preserving surgery. In addition to the radicality this aspect should be a primary goal to minimize morbidity. MRI is the first choice in the preoperative evaluation of neck desmoids. We describe the successful treatment of desmoid tumors in two cases (M. sternocleidomastoideus, M. levator scapulae). Intraoperative neuromonitoring was very helpful for identification and protection of the motor nerves.
