项目摘要

Objective: The object of the present study was to clarify the effect of Hotz Plate on the articulation of cleft palate children.Design: (1) We record and analyzed the tongue movement of cleft palate infants with and without Hotz Plate during sucking and swallowing by means of ultrasonography, and compared the result with that of normal infants. (2) We also examined the articilation of 15 children with Hotz Plate and compared the result with that of 91 cleft palate children with no history of the use of Hotz Plate. Results. (1) The downward movement of dorsum of the tongue during sucking was greater in the cleft palate cases than in the normal. This tendency was also seen in the cleft palate cases with Hotz plate. The result would suggest that even with Hotz Plate cleft palate infants could not make effective negative pressure sucking. (2) The articulation of children with Hotz Plate was not significantly different from that of those without Hotz Plate. More longitudinal data must be needed before we reach a conclusion on the effect of Hotz Plate on abnormal articulation. We found palatalyzed articulation in most of children with Hotz Plate made of hard resin, which was often loosely attached to the palate. Fitness of the plate to the palate seemed a significant factor to prevent abnormal articulation. Fistula were found in the children who had worn Hotz Palate until patatoplasty using a mucosal flap. The use of Hotz Palate should be discontinued at a certain time before the palataplasty in order to avoid excessive local stimulation.

目的：本研究旨在探讨Hotz板对腭裂患儿发音的影响，研究设计：（1）应用超声技术记录腭裂患儿使用Hotz板前后的舌运动，并与正常儿童进行比较。(2)我们还对15例使用Hotz钢板的腭裂患儿的发音情况进行了检查，并与91例无使用Hotz钢板的腭裂患儿的发音情况进行了比较。结果(1)腭裂患者舌背在吮吸过程中向下运动的幅度大于正常人。这种趋势也出现在腭裂病例与Hotz板。结果提示腭裂患儿即使使用Hotz Plate也不能进行有效的负压吸吮。(2)使用Hotz钢板与未使用Hotz钢板儿童的发音无显著差异。在我们得出Hotz接骨板对异常关节的影响的结论之前，必须需要更多的纵向数据。用硬树脂制成的Hotz板固定腭部时，大多数儿童出现腭化。接骨板与上腭的适合度似乎是防止异常发音的重要因素。瘘管被发现的儿童谁穿Hotz腭，直到Patatoplasty使用粘膜瓣。在腭裂修复术前的某个时间应停止使用Hotz Palate，以避免过度的局部刺激。
