FIGURE 2

Chronic postoperative temporal bone cavity inflammation focus surface area measurements. Otomicroscopical photographs of CPTBCI (i.e., chronically discharging radical mastoid cavity) in a patient at four checkups depict surface areas (mm2) transformed to percentages (italics) according to the baseline. The figure represents a regression of inflammation (i.e., spherical granulation) in a patient treated with PVRP. D5 marks the anatomical area of CPTBCI focus according to the anatomical classification (Supplementary Material 2) and in the upper left corner, an ID of the patient (Supplementary Materials 710). CPTBCI: chronic postoperative temporal bone cavity inflammation; PVRP: platelet- and extracellular vesicle-rich plasma.
