Cleft Palate Craniofac J. 1998 Nov;35(6):481-8. doi: 10.1597/1545-1569_1998_035_0481_vffsat_2.3.co_2.
This study was undertaken by several members of the University of Florida Craniofacial Center to assess the results of palatoplasty performed by the method devised by Larisa Y. Frolova, M.D. in 1971.
The assessment was based on evaluation of each subject's speech and velopharyngeal function through perceptual measures, nasometry, and video-nasendoscopy.
The study took place at the National Pediatric Center for Congenital Maxillofacial Pathology, Moscow, Russia, under the auspices and with the cooperation of Dr. Frolova, director of the program.
One hundred twelve children (40 girls and 72 boys; age range, 4 to 10 years; mean age, 7.5 years) with repaired cleft palate who had undergone palatoplasty 2 to 4 years earlier and had no secondary surgery were randomly selected from the center's clinical files by the staff. Subjects with known conditions that could jeopardize normal speech development were excluded.
Each subject was assessed for speech and velopharyngeal function with a battery of perceptual measures and videonasendoscopy.
The percentage of subjects judged to have normal resonance was 55.5%. An additional 9.5% of the subjects judged to be hyponasal increased the rate of nonhypernasal outcome to 64%.
The Furlow double-Z palatoplasty has had an increasing rate of success (up to 87%), whereas the Frolova technique has a success rate of only 55% to 65%.
本研究由佛罗里达大学颅面中心的几位成员开展，旨在评估采用拉里萨·Y·弗罗洛娃医生于1971年设计的方法进行腭裂修复术的效果。
评估基于通过感知测量、鼻音测量和视频鼻内镜检查对每位受试者的语音和腭咽功能进行评估。
该研究在俄罗斯莫斯科的国家先天性颌面病理学儿童中心进行，由该项目负责人弗罗洛娃医生主持并合作开展。
从该中心临床档案中随机挑选出112名腭裂修复儿童（40名女孩和72名男孩；年龄范围4至10岁；平均年龄7.5岁），这些儿童在2至4年前接受了腭裂修复术且未进行二次手术。排除已知可能危及正常语音发育情况的受试者。
使用一系列感知测量方法和视频鼻内镜检查对每位受试者的语音和腭咽功能进行评估。
被判定共鸣正常的受试者比例为55.5%。另外9.5%被判定为鼻音不足的受试者使非高鼻音结果的比例提高到64%。
弗洛氏双Z腭裂修复术的成功率不断提高（高达87%），而弗罗洛娃技术的成功率仅为55%至65%。
