Study on the Effect of Hotz's Palatal Plates for Cleft Lip and Palate Patients.

对早期接受唇裂成形术的唇腭裂新生儿，应用Hotz氏吸奶板，使其能像正常婴儿一样正常喂奶。结果表明：(1)腭板能有效地增加乳汁的摄入量，喂奶时间早在出生后5~6个月就恢复正常。(2)3岁儿童患龋率为42.1%，牙周炎患牙率为2.1%。(3)无先天缺失的儿童乳牙牙弓的宽度和长度与正常儿童相同。先天缺失组的牙弓宽度和长度均大于未使用腭板的患者。(4)在颅面发育方面，乳牙期未发现上颌发育不良、重度牙列畸形和多牙型。(5)在使用腭板的病例中，没有出现发音。(6)腭板对于唇腭裂患者获得正常口腔功能非常有效。

For newborn patients with the cleft lip and palate, who received the lip-plasty in an early stage, Hotz's plates applied to enable to feed milk normally as normal babies do.The results were as follows :(1) The palatal plates were so effective for increasing milk intake that feeding quantity and time became normal as early as from 5 to 6 months after birth.(2) The caries incidence rate of 3-year-old patients was 42.1% and df tooth rate 2.1, which were the same rates as these of normal children living in the same area.(3) The dental arch width and length in the primary dentition of the patients without congenital missing were as the same as these of normal children. In a congenital missing group, the dental arch width and length were larger than these of the patients without using palatal plates.(4) With regard to the craniofacial growth, undergrowth of the maxilla, severe Class lll cases and dolico types were not found in the stage of the primary dentition.(5) In the cases using palatal plates, no palatal pronunciation was produced.(6) The palatal plates were very effective for cleft lip and palate patients to gain normal oral function.
