Clinical value of ultrasound-guided percutaneous submandibular region puncture and drainage in the treatment of parapharyngeal space abscess / 中华超声影像学杂志

ABSTRACT

Objective:To investigate the feasibility and safety of ultrasound-guided percutaneous submandibular region puncture and drainage(PSPD) for treating parapharyngeal space abscess (PPSA).Methods:The clinical data of 26 patients with PPSA receiving PSPD from January 2015 to December 2019 in the Third Central Hospital of Tianjin were retrospectively analyzed.Results:All 26 patients successfully underwent puncture and catheterization with a primary success rate of 100%. After catherization, pain relieved within 12-24 hours, body temperature returned to normal within 24-48 hours, white blood cell(WBC) and C-reactive protein(CRP) returned to normal within 48-96 hours. The catheterization duration ranged from 5 to 14 days and the average time was 7 days. There were statistically significant differences in the body temperature, maximum abscess diameter, WBC and CRP between pre-operation and 7 days after operation(all P<0.001). None of the 26 patients experienced any serious complications such as major vessels, nerve or glands injury. Bacterial cultures were positive in 18 patients and the most common bacteria was hemolytic streptococcus. Conclusions:PSPD is an effective, safe and minimally invasive method for the treatment of PPSA as an alternative to operative incision and drainage.
