Abstract:
Objective To explore the curative effects on surgical methods for the prevention of Frey syndrome and a concave facial deformity after parotidectomy.Methods A literature search was performed using the Wanfang Database,Chinese Biomedical Literature Disk Database,Chinese Digital Hospital Library and Chinese Scientific Journals Database of VIP from January 1989 to December 2008.Twenty-six Chineselanguage controlled studies involving surgical techniques for prevention of Frey syndrome and the concave facial deformity after parotidectomy were identified.Review manager 4.2 software was applied for Meta analysis.Results Meta-analysis for surgical techniques to prevent symptomatic Frey syndrome,a positive starch-iodine test,and contour deformity,favored intervention with a cumulative odds ratio ( OR) of 0.14 [95% confidence interval (CI) ,0.07-0.25] ;OR,0.21 (95% CI,0.17-0.26) ;and OR,0.09 (95% CI,0.04-0.19) ,respectively.There was a significant difference in the incidence of these complications between surgical treatment groups and control groups ( Z = 6.42,Z = 13.70,Z = 6.43,all P ＜ 0.05 ).The application of a sternocleidomastoid muscle flap decreased the incidence of symptomatic Frey syndrome ( Z =2.33,P ＜ 0.05),positive starch-iodine test (Z = 1.48,P ＜ 0.05) and contour deformity (Z = 7.78,P ＜0.05).The application of acellular dermal matrix decreased the incidence of symptomatic Frey syndrome (Z =6.02,P ＜ 0.05 ) and positive starch-iodine test ( Z = 5.72,P ＜ 0.05 ) but did not decrease the incidence of contour deformity (Z = 1.27,P ＞ 0.05).Conclusion Meta-analysis of operative techniques to prevent symptomatic Frey syndrome,a positive starch-iodine test,and facial asymmetry suggests that such methods are likely to reduce the incidence of these complications and improve the quality of life after parotidectomy.
