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.

Division of the orbit into 4 quadrants. The superior lid crease approach allows access to the superior quadrant, the precaruncular incision allows access to the medial quadrant, the lateral retrocanthal incision allows access to the lateral quadrant, and the transconjunctival incision allows access to the inferior quadrant.

Figure 1: Division of the orbit into 4 quadrants. The superior lid crease approach allows access to the superior quadrant, the precaruncular incision allows access to the medial quadrant, the lateral retrocanthal incision allows access to the lateral quadrant, and the transconjunctival incision allows access to the inferior quadrant.

Mentions: Moe et al. describe approaches to the 4 quadrants of the orbita under the term of “TONES”, which stands for “transorbital neuroendoscopic surgery”. Since Moe’s classification of incisions is most appropriate to analyze transorbital approaches in a structured way, this classification will be taken as basis for this manuscript [1], [2]. As presented in Figure 1 (Fig. 1), the approaches are divided according to the quadrants.
