Abstract

The aim of this work is to study the use of this technique for extirpation of malignant tumors of the maxillary sinus and application for a variety of facial lesions, craniofacial deformities and trauma sequel. This includes the exposure for adequate tumor resection and the preservation of tissues and they function. This approach was evaluated including the advantages and disadvantages regarding the function, aesthetic outcome and the complications related to the procedure.

Highlights

The Craniofacial approaches can be used for the radical resection of lesions in the middle and anterior cranial fossa
In two cases of panfacial sequeal with subcondylar fracture the dismasking flap was extended with preauricular rhytidectomy approach and the facial nerve was dissected for open reduction of the fracture
With the dismasking flap approach, it is possible to resect tumors of the anterior cranial base that extend to the nasal, orbital and maxillary regions, allowing other surgical procedures such as partial or vertical partial maxillectomy (Stage T1 or T2 tumors), total maxilectomy and maxilectomy enlarged to the skin, orbit, infrasphenotemporal fossa and skull base in neoplasms invading the skin, orbit, retromaxillary region or base of the skull [9,18,19,20]

Summary

Introduction

The Craniofacial approaches can be used for the radical resection of lesions in the middle and anterior cranial fossa. Derome, [4] and Tessier were pioneered craniofacial approaches for correction of deformities and resection of tumor lesions in the anterior and middle cranial fossa. These approaches are carried out in adults, but their use in children requires a modification to avoid endangering craniofacial growth [1,5]. The technique involves a combination of coronal and circumpalpebral incisions. With this technique, the facial skin together with the facial nerves and muscles is “Dismasked,” that is, peeled inferiorly, and a wide exposure of the facial
