Comparison of effects of nasal endoscopic adenoid body excision and conventional adenoid body shaving in the treatment of adenoid hypertrophy

Objective To compare the effect of adenoidectomy with adenoidectomy under nasal endoscope in the treatment of adenoid hypertrophy. Methods 120 cases with adenoid hypertrophy were selected as the research subjects.The patients were randomly divided into two groups by random number table, and the control group(n=60) was treated with routine adenoidectomy.The surgical treatment of the observation group(n=60) was performed under nasal endoscope.Surgical treatment, surgery related indicators(operative time, the average amount of bleeding, hospitalization time and the incidence of postoperative complications) were compared between the two groups.Before and after operation, acoustic rhinometry examination of nasopharynx was used to detect the smallest cross-sectional area and compared. Results In the observation group, the operation time, the average amount of bleeding, hospitalization time and incidence rate of postoperative complication were (5.32±2.05)min, (51.05±8.26)mL, (8.50±2.50)d, 15.00%, respectively, which in the control group were (8.56±2.68)min, (78.45±10.15)mL, (12.00±3.50)d, 36.67%, respectively, there were significant differences between the two groups(t=7.44, 15.98, 6.30, χ2=7.35, all P<0.05).12 months after surgery, the nasal minimal cross-sectional area of nasal pharynx in the observation group was (1.99±0.51)cm2, which of the control group was (1.81±0.48)cm2, there was significant difference between the two groups(t=3.99, P<0.05). Conclusion Compared with conventional adenoidectomy, endoscopic adenoidectomy in the treatment of adenoid hypertrophy has good clinical curative effect, less bleeding, shorter operative time and less postoperative complications and other advantages, it is worthy of promotion.
