Abstract:ObjectiveTo investigate an effective method for prevention of septal hematoma after nasal endoscopic correction of nasal septum.MethodsClinic data of 220 patients admitted to the first affiliated hospital of anhui medical university was analyzed retrospectively. The patients underwent an endoscopic septoplasty under nasal endoscopy from January 2016 to April 2019. Ninety cases of the 220 patients had intact mucosa on both sides of the nasal septum after nasal septum correction, who were defined as group A; The incisions of the septum mucosa in 90 patients with intact mucosa postoperation were cut for 1 cm at the proximal nasal base named as a mucosal assisted incision. And the 90 patients were defined as group B. Forty patients had an asymmetry broken in the nasal septum mucosa on one or both sides after surgery, which was defined as group C. All patients of the 3 groups were filled with expanded sponge.ResultsThere were septal hematoma in 5 cases of group A. No septal hematoma occurred in all patients of group B or group C. No nasal septum perforation was found in all cases. There was a statistically significant difference in the incidence of septal hematoma between the three groups (P<0.05).ConclusionThe patients with intact nasal septum mucosa on both sides after operation, the septal mucosal incision of one side after septoplasty can effectively prevent the occurrence of nasal septum hematoma .
