Clinical features and literature review related to the material differences in thread rhinoplasty: Two case reports

Figure 1 Photographic finding of case one’s initial visit. Erythema and pus drainage with skin necrosis at the nasal dorsum were observed.

Figure 2 Photographic finding of patient’s initial visit. Erythema with skin necrosis was observed at the nasal tip.

Figure 3 Hounsfield unit measurement of case one. A: Inflammatory tissue; B: Calcified lesion estimated as polydioxanone (PDO); C: Inflammatory tissue at POD #5. It can be seen that the HU values decreased compared to the preoperative period. HU: Hounsfield unit.

Figure 4 Hounsfield unit measurement of case two. A: Preoperative measurement on suspected inflammatory tissue; B: Inflammatory tissue at polydioxanone #8.

Figure 5 Clinical features of the patient one. A: Intraoperative finding. capsule and foreign body granuloma (white arrow) around the polydioxanone (PDO) were observed in the sub-superficial musculoaponeurotic system layer; B: PDO fragment broken down into multiple pieces; C: Histopathological findings (Hematoxylin-eosin staining, magnification × 200).

Figure 6 Clinical features of patient two. A: Polypropylene threads with a barbed pattern located between medial crura of the lower lateral cartilage (white arrow); B: Removed barbed pattern thread; C: Histopathological findings (Hematoxylin-eosin staining, magnification × 200).
