Abstract
The purpose of this article is to investigate the clinical effect of CT-guided ozone-blowing and fumigation in the treatment of chronic refractory cutaneous sinus and ulcer. Twenty-six cases of chronic refractory sinuses and ulcers caused by different diseases were retrospectively analyzed in our study. After sterilization, all patients were scanned by computed tomography and the sinuses and ulcers prelocated by CT were treated by O3-blowing and fumigation. Twenty-one patients treated with traditional surgery were randomly assigned into control group. A total number of 15 patients were completely cured in 45 days after receiving CT-guided ozone-blowing fumigation treatment. Four patients exhibited markedly therapeutic effects and three cases showed improvement. The effective ratio was 85%. In control group, seven patients were completely cured in 45 days after being treated by traditional surgery. Four patients exhibited markedly therapeutic effects and five cases showed improvement. An obvious statistical difference exists between two groups. Application of CT-guided O3-blowing and fumigation therapy is an effective approach in the treatment of chronic refractory cutaneous ulcer and sinus with shorter therapeutic duration, less suffering, better curative effect and less adverse effect.
