Soft Palate Modification Using a Collagen Crosslinking Reagent for Equine Dorsal Displacement of the Soft Palate and Other Upper Airway Breathing Disorders

Figure 6

Histological observations from safety phase soft palates. There were moderate-to-extensive regions of tissue disruption and patchy necrosis with mild-to-moderate inflammatory and fibroplastic responses in viable tissue in both treated and untreated regions of the soft palate, believed to be due to the consistently observed excessive expansion of the soft palate (pillowing) during the injections.
