Due to vascular damage after radiotherapy, hypoxia led to increased postoperative complications. The authors attempted to quantitatively analyze the pathology and histomorphology of the irradiated and injured soft tissue of the jaw. Forty patients with mandibular radiosclerosis who underwent surgical resection were enrolled in the study, and histopathology and histomorphology were examined. Results: Histopathological examination revealed that 7 cases of radioactive bone necrosis experienced congestion, endocarditis, thrombosis, apoptosis, tissue ischemia, myelin
