Clinical investigation of CT-guided ozone-blowing and fumigation therapy for the chronic refractory cutaneous sinus and ulcer

摘要

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 pre-located 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?therapeuticeffects?and three cases showed improvement. The effective ratio was 85%. Incontrol 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.
