“…The surgical approach of the Dismasking flap was developed for the removal of tumor lesions not only located in the skull but also in the facial region and in surgeries that require extensive surgical fields. Because in other types of approaches they present limitations in the surgical field and show postoperative cosmetic results in the facial region [15][16][17].…”

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.

Object In 1997 the authors presented the case of a 3-year-old girl who underwent complete resection of a huge tumor via a new technique using a dismasking flap. Since that report, 14 patients have undergone surgery using this technique. There have been few reports on long-term follow-up after a craniofacial surgical approach and reconstruction of a huge tissue defect. The authors report details of this procedure based on these cases, including long-term follow-up in the original case. Methods The dismasking flap is a cranioorbitofacial degloving method that uses a circumpalpebral approach with or without piriform margin incisions and presents a wide surgical field under direct vision. Fourteen patients have undergone surgery using the dismasking flap technique. These patients had multiple craniofacial bone fractures (3 cases) and malignant or premalignant craniofacial tumors (11 cases). Patients ranged in age from 3 to 62 years old. The longest follow-up period was 15 years. The results of these cases are reported regarding changes in the facial bones and soft tissues with growth, the various pathologies involved, and complications. Results Complications using this approach were lagophthalmos with ectropion of the lower eyelid, disturbance of the superior orbital nerve, disturbance of the inferior orbital nerve, maxillary hypoplasia, and blepharoptosis. In all affected patients these complications were almost always temporary. In 2 of the 14 cases, a repair operation for lagophthalmos was necessary, while others showed spontaneous improvement approximately 6 months to a year after the procedure. In the case with the longest follow-up duration, the patient's nose is asymmetrical, especially the alar portion, due to hypoplasia of the grafted bone and/or the fixation with titanium miniplates. Conclusions This flap is very useful for en bloc resection of huge skull base tumors, multiple craniofacial bone fractures, and as a lateral approach to a deep portion of the middle cranial base. Careful attention is necessary, however, because one may encounter unexpected complications if one does not ensure adequate protection of the perioperative flap. Meticulous postoperative management is also essential.

Maxillary removal and reinsertion: A favorable approach for extensive anterior cranial base tumors

Abstract: MRRI is a favorable surgical technique for the treatment of anterior cranial base (ACB) tumors in adults and even in children. It improves operative morbidity by preserving both function and form of the maxillary region and gives excellent exposure to ACB.
