Minimally invasive surgery of the anterior skull base: transorbital approaches.

Gassner HG, Schwan F, Schebesch KM - GMS Curr Top Otorhinolaryngol Head Neck Surg (2016)

Bottom Line: The more recently described transorbital approaches represent minimally invasive alternatives with a differing spectrum of access corridors.The purpose of the present paper is to discuss transorbital approaches to the anterior skull base in the light of the current literature.Their execution requires an interdisciplinary team approach.

ABSTRACT
Minimally invasive approaches are becoming increasingly popular to access the anterior skull base. With interdisciplinary cooperation, in particular endonasal endoscopic approaches have seen an impressive expansion of indications over the past decades. The more recently described transorbital approaches represent minimally invasive alternatives with a differing spectrum of access corridors. The purpose of the present paper is to discuss transorbital approaches to the anterior skull base in the light of the current literature. The transorbital approaches allow excellent exposure of areas that are difficult to reach like the anterior and posterior wall of the frontal sinus; working angles may be more favorable and the paranasal sinus system can be preserved while exposing the skull base. Because of their minimal morbidity and the cosmetically excellent results, the transorbital approaches represent an important addition to established endonasal endoscopic and open approaches to the anterior skull base. Their execution requires an interdisciplinary team approach.

Figure 12: Reconstruction of the continuity of the anterior wall and the floor of the frontal sinus by micro-plate osteosynthesis.

Mentions: Superior extension: The temporary removal of the anterior wall and floor of the frontal sinus allows access to the posterior wall. The anterior wall segment can be split sagittally at the level of the supraorbital foramen in order to protect the supraorbital nerve (Figure 11 (Fig. 11)). Access to the posterior aspects of the interorbital corridor is created and to the lamina cribrosa and the crista galli are exposed as described in the presented case. Resection of the frontal sinus septum in the sense of Draf III surgery can also be performed in this way. The anatomical continuity of the frontal sinus walls is restored by osteosynthesis with micro-plates (Figure 12 (Fig. 12)). Figure 13 (Fig. 13) illustrates the postoperative result of the 16-year-old patient one year after dural repair with unimpaired function and cosmetic appearance.
