Abstract:To study the clinical effect of nasal endoscopic cystic surgery with nasal endoscopic cryoplasma. Methods 60 patients with nasal vestibular cysts from January 2014 to January 2018 were enrolled as study subjects. They were divided into control group and study group randomly 30 cases in each. The control group received a conventional cleft lip and incision approach to remove cysts. The study group underwent endoscopic cryo-plasma resection for cysts. The surgical parameters, postoperative swelling, pain, inflammatory factors, complications, etc. were compared between the two groups. Results The study showed that the operation time, intraoperative blood loss, postoperative wound healing time and epithelialization time of the study group were significantly better than that in control group, the difference was statistically significant (P < 0.05); Moderate and severe swelling after surgery, moderate and severe pain of wound in study group were significantly lower than that of the control group, and the difference was significant (P < 0.05). Tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), interleukin-8 (IL-8), C-reactive protein (CRP) levels in study group at 5 day after surgery were significantly lower than the control group, and the difference was statistically significant (P < 0.05); The overall incidence of infection, numbness, nasal vestibular discomfort and recurrence rate at 6 months after surgery in study group were significantly lower than the control group, and the difference was statistically significant (P < 0.05). Conclusion Endoscopic low-temperature plasma surgery compared with traditional cleft lip incision approach for cystectomy for nasal vestibular cysts has less trauma to the patient, helps promote wound healing, reduces postoperative swelling and pain, and has low postoperative inflammatory response. The complications and recurrence rate are low, which is worthy of clinical application.
