持续负压引流术治疗严重颌面颈部间隙感染的探讨

目的 应用持续的负压引流术治疗严重颌面颈部间隙感染，观察其疗效。方法 采用持续负压引流术治疗18例严重颌面颈部间隙感染患者。在患者感染部位肿胀最明显或波动处用小切口切开引流，放置负压引流装置，同时缝合封闭创口，持续负压引流。结果 18例患者中，14例患者经持续负压引流至肿胀及疼痛消退，然后拔除引流管；4例患者术后创口破溃，负压消失而拔除引流管，改用其他无负压引流方法。所有患者术后肿胀疼痛未加重，无窒息、感染性休克、纵膈脓肿等并发症发生，均痊愈出院。结论 持续负压引流术为治疗严重颌面颈部间隙感染的方法多了一种选择，该方法改变了传统的脓肿切开引流的治疗方式，减少了患者的痛苦，同时也减轻了医生的工作负担。

Sustained negative pressure drainage for treatment of severe maxillofacial and neck space infection

Objective This study observed the curative effect of sustained negative pressure drainage application on treatment of severe maxillofacial and neck space infection. Methods Incision and drainage were performed to treat 18 patients with severe maxillofacial and neck space infection. A small incision was made on the site of the most obvious swelling or fluctuations, and localized negative pressure was applied with a drainage device on the wound during suturing. Results Among the 18 patients, 14 were healed, whereas 4 underwent dehiscence of the wound after the operation. Negative pressure was lost as the drainage tubes were removed, and non-negative pressure drainage method was used instead. During the negative pressure treatment, swelling and pain did not increase after the operation. Other complications, such as asphyxia, septic shock, or mediastinal abscess, did not occur. All the patients were healed and eventually discharged from the hospital. Conclusion Sustained negative pressure drainage, which is a modified version of the traditional method of incision and drainage, is an alternative treatment for severe maxillofacial and neck space infection. Such treatment reduces patient pain and eases doctor exertion. Thus, this method provides a new therapeutic strategy for severe maxillofacial and neck space infection.
