Application of Silicone Catheter in Continuous Negative Pressure Suction after Auricular Reconstruction with Expanded Method
Objective To investigate the clinical application effect of a negative pressure drainage device made of silicone catheter,disposable suction tube and 20ml disposable syringe after dilated ear reconstruction.Methods From January 2021 to January 2022,30 patients with expanded ear reconstruction in the author's hospital were collected.The drainage effect,negative pressure adjustment times,suction and closure times,postoperative complications,and auricle and substructure development were observed.Results The results of a small clinical trial show that after two times of air suction in the flow tube,the ordinary disposable drainage tube became soft and slightly deformed.Infusion set drainage tube completely suction closed.The silicone catheter has no deformation and suction phenomenon.The silicone catheter was used as a drainage tube,the blood supply of the flap was good,the substructure of the auricle was satisfactory,and there was no phenomenon of aspiration closure and infection.All incisions healed by first intention.The average drainage volume of the wound was 8～17ml daily,and the time to extubation was from 4～7 days.Conclusion The device can not only make the flap fit closely with the ear scaffold,ensure the satisfactory shape of the reconstructed ear,but also fully drain the ear to achieve zero suction closure.Its antibacterial and anti-infection material and double cavity structure can also reduce the incidence of infection and provide the opportunity of prophylactic antibiotic irrigation.
