[Analysis of related factors of postoperative complications of Juvenile-onset recurrent respiratory papillomatosis].

To analyze the causes and related factors of postoperative complications of Juvenile-onset recurrent respiratory papillomatosis（JORRP）. One hundred and seventy cases of JORRP who underwent surgical treatment in Beijing Tongren Hospital of Capital Medical University from 2017 to 2019 were followed up, and the types of complications, age of first operation, number and frequency of operations, and underwent tracheotomy or not were reviewed. According to the presence or absence of postoperative complications, the patients were divided into a complication group and a control group, and the differences between the two groups and related factors causing postoperative complications were compared. In the 170 cases, 75（44.12%） had postoperative complications, including 52（69.33%） cases of vocal cord adhesion, 37（49.33%） cases of lower airway diffusion, and 25（33.33%） cases of laryngeal stenosis in the complication group. The age of first operation was among 0.3-14 years old, and the total number of surgeries was 14.52（1-54） for each patient during the observation period, with an average annual number of 2.93（0.04-18.39）. Compared with the control group, the complication group had 19.07±13.12 total surgeries, the control group had 10.97±9.41 surgeries（<0.01）, annual surgeries ≥4 times（=0.034）, postoperative complications after tracheotomy（=0.007）, and underwent low temperature plasma radiofrequency ablation and photodynamic therapy were more likely to occur than those treated with CO2laser only（<0.01）. The postoperative complications of JORRP include vocal cord adhesion, laryngotracheal stenosis, lower airway dissemination, etc. Multiple and frequent operations, tracheotomy, and different surgical methods are closely related to postoperative complications. The risk of postoperative complications may be increased when children are younger in age of initial operation and with more frequency of surgeries.
