ABSTRACT
Lymphoscintigraphy is used to identify ambiguous drainage patterns in cutaneous melanoma of the head, neck and trunk. This study evaluated the efficacy and reliability of lymphoscintigraphy to identify the drainage nodes in 51 patients undergoing both elective and therapeutic lymphadenectomy over a seven-year period. All 13 patients who had lymph node metastases during this follow-up period had the metastatic disease in the very lymph node basins identified by lymphoscintigraphy. Most significantly, none of the 51 patients had metastatic disease in lymphatic basins that were not previously identified by lymphoscintigraphy.

Sagittal synostosis comprises a spectrum of deformities caused by premature fusion of the sagittal suture. The treatment of sagittal synostosis is dependent on the age of the patient and the characteristics of the presenting deformity. Immediate correction of the scaphocephalic deformity is the goal of operative treatment. The operative procedures proposed involve whole-vault cranial reshaping, active shortening of the anteroposterior axis, and widening of the mediolateral dimension of the skull leading to a more normal, "rounded" skull shape.
