Axial Subcutaneous Scalp Flaps in the Reconstruction of the

resection of upper aerodigestive tract tumors involving the anterior cranial fossa is the difficultyin recon¬ structing the floor of the anterior skull base with a viable, watertight separation between these two sites.1'3 Such reconstruction has traditionally involved full-thickness scalp flaps, skin grafts, and, most recently, free flaps.15

Unfortunately, advances in the reconstruction after endoscopic endonasal approaches lagged signifi - cantly behind advances in the approach and resection of tumors of the skull base.

Anterior craniofacial resection for paranasal sinus tumors

accounting for 4% of all plasma cell tumors, mainly arising in the head and neck, particularly the upper aerodigestive tract. Plasmacytomas generally present as bone or soft-tissue tumors with a variable mass effect, pain, and infiltrative behavior [2]. The typical clinical features of MM are bone pain, weakness, fatigue, fever and infection.

Region III defects are almost all associated with tumors arising from the ear,parotid, or temporalbone,and theymay extend into the middle or posterior cranial

Sinonasal malignancies are arare subset of malignancies of the upper aerodigestive tract which had been traditionally approached via open techniques. This article pri-marily addresses a paradigm shift in endoscopic endonasal oncological resection utilizing principles of tumor disassembly and negative margins. The surgical steps

During surgery and after en-bloc resection, two nylon catheters spaced 1 cm apart were positioned in the area of gross residual disease (figure 2), and were

Involvement of the frontal lobe, orbit, or skin does not preclude resection.

These resections involve removal of cranial bone, with or without incision of the dura. The classification system described by Irish and colleagues5 remains the most useful for describing skull base
