Foster child hemangioma management depends on its usual spontaneously regressive evolution as it is a transient and benign vascular tumor like lesion. Most of the time clinical follow up is the only management. Investigations are indicated if treatment is needed (for decision and follow up) concerning only hemangiomas with a bad functional or esthetic prognosis (peri-orificial lesions and large locations of the face) or complicated hemangiomas with life-risk as sub glottic hemangioma, Kasabach and Merritt Syndrome, diffuse and liver hemangiomatosis possibly associated to cardiac failure. Basic treatment remains systemic corticosteroids with indications for early surgery or intralesional corticosteroids.
Intraoperative facial nerve monitoring with electrical stimulation (IFNMES) has become an integral part of acoustic tumor surgery. We reviewed the records of fifty-six patients who underwent translabyrinthine acoustic tumor removal with IFNMES. There was excellent correlation between intraoperative facial nerve activity and immediate postoperative facial nerve function (24 hours after surgery and at hospital discharge). Our data would suggest that patients who exhibit less than 500 microvolts of ongoing EMG activity during surgery, and who yield at least a 500-microvolt contraction when stimulated with 0.05 milliamps at the brainstem after tumor removal, can expect an excellent immediate facial nerve result (grade I or II).
