“…The corrosion cast technique provides an understanding of the angioarchitecture of normal or altered anatomical structures (Lametschwandtner et al, 1990). Sometimes, the use of the technique is difficult because of the fragile vascular casts obtained, since the supporting tissue of the vessels is removed in the process (Hodde et al, 1990;Kronka et al, 2001;Lametschwandtner et al, 1990;Selliseth and Selvig, 1995;Sugioka and Ike, 1993;Weekes and Sims, 1986;Ohta et al, 1992). In the present study, taking into account the fragility of the cast and the delicate nature of the salivary glands, the structures were removed en bloc, such that this contained the two submandibular glands, the two sublingual glands, and the regional lymph nodes.…”
