Abstract
ObjectiveThe aim of this study was to evaluate the therapeutic effects of intralesion injection of pingyangmycin in combination with triamcinolone acetonide or pingyangmycin alone on lymphatic malformations in oral and maxillofacial regions. MethodsTwenty-nine cases with lymphatic malformations in the oral and maxillofacial region were divided into experimental and control groups. Thirteen patients in the experimental group underwent intralesion injections of pingyangmycin in combination with triamcinolone acetonide, and 16 patients of control group underwent intralesion injections of pingyangmycin alone. The effects of treatments were assessed by measuring lesion volume and facial deformity before and after treatment. ResultsTwo years after the treatment, the volumes of macrocystic and microcystic lesions were 3.7% ± 0.3 and 4.2% ± 0.4 of pre-treatment volume in the experimental group, respectively, whereas the volumes of macrocystic and microcystic lesions in control group were 15.4% ± 1.3 and 24.1% ± 3.1, respectively. Facial appearance was satisfactory in all subjects in the experimental group, whereas facial asymmetry remained in varying degree in control group. ConclusionIntralesion injection of pingyangmycin with triamcinolone acetonide was more effective than pingyangmycin alone for treatment of lymphatic malformations in oral and maxillofacial regions.
