RESUMO
Objective@#The aim of this study is to explore the application and advantages of combined intrathecal and extrathecal hypothermic plasma tonsillectomy in reducing intraoperative and postoperative hemorrhage in OSA children. @*Method@#We retrospectively reviewed 726 cases who were diagnosed as OSA. All patients were divided into two groups according to the surgical method: 320 cases by total tonsillectomy and 406 cases by combined extracapsular and intracapsular tonsillectomy. The intro operative bleeding volume, post operative haemorrhage data as time, location and degree in the two groups were compared. @*Result@#There was no statistical difference in the intro operative bleeding volume in the two groups [（9.3±4.6） mL]vs [（7.6±3.5） mL], t=12.687, P=0.235. Two patients who underwent combined extracapsular and intracapsular tonsillectomy presented with post operative haemorrhage, the total post operative haemorrhage rate was significantly decreased that in the total tonsillectomy group（14 cases）（χ²=10.779, P=0.001）. The 2 patients in combined extracapsular and intracapsular tonsillectomy group were secondary haemorrhage, with location in the upper pole and medium, grade A haemorrhage; while in the 14 cases in in the total tonsillectomy group, there were 2 cases presented with primary haemorrhage and 12 cases with secondary haemorrhage; with regard to location of haemorrhage, 1 in the upper pole, 2 in the medium, 11 in the lower pole; 5 cases presented with grade A haemorrhage, 8 with grade B haemorrhage and 1 with grade C haemorrhage. The haemorrhage rate at 7 days after surgery （χ²=5.697, P=0.017）, at the lower pole（χ²=11.961, P=0.001） and grade B（χ²=8.097, P=0.004） were all significantly decreases in the combined extracapsular and intracapsular tonsillectomy group. @*Conclusion@#Plasma tonsillectomy combined with intrathecal and extrathecal hypothermic tonsillectomy is a safe and effective method, which has obvious advantages in reducing the postoperative hemorrhage, especially the secondary hemorrhage of Subtonsillar Pole.

The intro operative bleeding volume, post operative haemorrhage data as time, location and degree in the two groups were compared. There was no statistical difference in the intro operative bleeding volume in the two groups [（9.3±4.6） mL]vs [（7.6±3.5） mL], =12.687, =0.235. Two patients who underwent combined extracapsular and intracapsular tonsillectomy presented with post operative haemorrhage, the total post operative haemorrhage rate was significantly decreased that in the total tonsillectomy group（14 cases）（χ²=10.779, =0.001）. The 2 patients in combined extracapsular and intracapsular tonsillectomy group were secondary haemorrhage, with location in the upper pole and medium, grade A haemorrhage; while in the 14 cases in in the total tonsillectomy group, there were 2 cases presented with primary haemorrhage and 12 cases with secondary haemorrhage; with regard to location of haemorrhage, 1 in the upper pole, 2 in the medium, 11 in the lower pole; 5 cases presented with grade A haemorrhage, 8 with grade B haemorrhage and 1 with grade C haemorrhage. The haemorrhage rate at 7 days after surgery （χ²=5.697, =0.017）, at the lower pole（χ²=11.961, =0.001） and grade B（χ²=8.097, =0.004） were all significantly decreases in the combined extracapsular and intracapsular tonsillectomy group. Plasma tonsillectomy combined with intrathecal and extrathecal hypothermic tonsillectomy is a safe and effective method, which has obvious advantages in reducing the postoperative hemorrhage, especially the secondary hemorrhage of Subtonsillar Pole.
