Complicated calcified alloplastic implants in the nasal dorsum: A clinical analysis

Figure 1 Four different compartments of the silicone nasal implant. TD: Tip dorsum; TB: Tip base; CD: Cephalic dorsum; CB: Cephalic base.

Figure 2 Gross findings of calcified nasal implant. A: A calcified capsule (orange arrows) is observed around the implant; B: Another implant with severe multifocal peri-implant calcification.

Figure 3 Histopathologic findings of calcified nasal implant. A: Calcified material surrounded by fibrotic tissue. Amorphous, irregular-shaped, basophilic deposits (orange arrowheads) suggesting dystrophic calcification were found surrounding the foreign material and fibrous tissue; B: Adjacent soft tissue exhibits a mild lymphocytic infiltration and a few foreign body-type giant cells (yellow arrowheads). Hematoxylin and Eosin staining, 500 μm.

Figure 4 Histopathologic findings of peri-implant tissue. A: Dispersed multinucleated giant cells (orange arrowheads) in the surrounding fibrotic stroma; B: Sparse lymphocytic infiltration (yellow arrowheads) is also observed in the stroma. Hematoxylin and Eosin staining, 200 μm.

Figure 5 Computed tomography findings of calcified nasal implant. A: A thick calcified capsule observed on the implant; B: Extensive peri-implant calcification surrounding with the right-side deviated implant.

Figure 6 Relationship between the duration of the implant and the median value of Hounsfield unit.

Figure 7 Bending strength test of soft silicone implant. A: The implant on the above is a hard type implant (MISTI^®; KEOSAN Trading, Seoul, Korea), and the implant on the below is a soft type nasal implant, (SOFTXIL^®; BISTOOL, Seoul, Korea); B: It can be observed that the soft type nasal implant (left, orange arrow) bends much better when a mild grasping force is applied.
