[Head and neck superficial venous malformations].

Management of vascular malformations and vascular tumors has recently been maximized by the establishment of an accurate clinical and histological classification and by the development of multidisciplinary expert consultations. Head and neck localizations of venous malformations are common, thus maxillo-facial surgeons should be aware of the characteristics of this pathology and the principles of its management. Diagnosis is mainly clinical and must be certified by Doppler-ultrasonography and contrast enhanced magnetic resonance imaging with T2 fat-saturation sequence. Therapeutic decision depends on the volume of the lesion, and on functional, cosmetic and psychological complaints. Sclerotherapy is now the preferred treatment of head and neck venous malformations. It is performed in specialized interventional radiology units by intralesional injections of sclerosing solution under fluoroscopic guidance. Surgery is useful in some cases, either on its own or following sclerotherapy. In case of bulky lesion, it is necessary to search for and prevent a severe coagulopathy before planning any intervention.
