[Clinical study of radiofrequency ablation combined with lauromacrogol for the treatment of parotid gland hemangioma in infants].

Objective: To investigate the clinical effect of radiofrequency ablation (RFA) combined with lauromacrogol for the treatment of parotid gland hemangioma in infants.

Methods: From Sep.2005 to Dec.2014,a total of 117 patients with parotid gland hemangioma were divided into observation group (n =32),control group 1 (n =30),control group 2 (n =28) and control group 3 (n =27).The observation group was treated by RFA combined with lauromacrogol, while the control group 1 was treated by RFA only, the control group 2 was treated by pingyangmycin only, and the control group 3 received additional pingyangmycin based on RFA. All the patients were followed up for 6 to 24 months, and the clinical effects were observed in four groups.

Results: Control group 1:16 patients were cured (53.3％),and the number of patients with ≥2 treatments was 9.There was 1 case with skin ulceration,1 with abdominal discomfort,1 with liver function damage and 1 with high fever.Control group 2:17 patients were cured(60.7％),and number of patients with ≥2 treatments was 12.There were 3 cases with skin ulceration,9 with abdominal discomfort,6 with liver function damage and 5 with high fever.Control group 3:21 patients were cured(77.8％),and number of patients with ≥2 treatments was 2.There were 2 cases with skin ulceration,6 with abdominal discomfort,4 with liver function damage and 4 with high fever.However,in observation group,25 patients were cured(78.1％) and number of patients with ≥ 2 treatments was 4,which were significantly different from that in control group 1 or control group 2 (P ＜0.05).And the difference in postoperative adverse reactions between observation group and control group 2 or control group 3 was also of significance (2 with skin ulceration,1 with abdominal discomfort,1 with liver function damage and 6 with high fever,P ＜ 0.05).

Conclusions: Combined RFA and lauromacrogol has a good therapeutic effect on parotid gland hemangioma with relatively low adverse effect, so it deserves to be suggested and applied in clinical practice.
