Congenital healed cleft lip

Congenital “healed” cleft lip (CHCL) is an unusual anomaly including a paramedian “scar” of the upper lip, which appears as if a typical cleft lip has been corrected in utero. The CHCL is frequently associated with an ipsilateral notch in the vermilion, and “collapsed” nostril. Twenty-five CHCL cases are presented, eighteen of which were an isolated malformation found among the 3,950,715 births examined in two similar birth defect registries: ECEMC in Spain and ECLAMC in Latin America. Like open cleft lip, of which it seems to be a variant, CHCL is most frequently seen among males (14/18 isolated cases), it preferentially affects the left side (10/18 cases), and it segregated together with cleft lip in one family. The five CHCL cases with other congenital anomalies included: two cases with hydrocephalus, two VACTERL associations, and one atypical oblique facial cleft infant with single umbilical artery. CHCL may result from a defective fusion of the frontonasal and maxillary processes (before week 7 of embryonic life), or from a spontaneously repaired open cleft lip, later on. In either way, these cases heal with a visible scar, and the pre-occurrence of CHCL in two families suggests a familial predisposition to this phenomenon. © 1995 Wiley-Liss, Inc.     

继发性唇裂鼻畸形硅胶植入整复术

本文介绍一种使继发性唇裂鼻畸形获得较好外形的新手术方法。术式包括切除偏曲的鼻中隔软骨,并将一片硅胶植入于中央作为鼻小柱支柱,从而矫正歪斜的鼻小柱和抬高鼻尖,使两侧鼻孔形态对称一致,用本法为11例单侧唇裂畸形较重者进行了整复,随访4个月至4年半。绝大多数(10/11)取得满意效果,未见有严重感染和变形等并发症。     

改良Millard法修复单侧重度完全性唇裂

目的：探讨一种修复重度完全性单侧唇裂的方法。方法：应用改良Mi11ard法与裂隙缘粘膜瓣联合应用修复单侧重度完全性唇裂，笔者自2000年始应用此法对单侧完全性重度唇裂的鼻槛修复及口、鼻瘘口封闭、鼻堤重建效果满意。21例患者创口均Ⅰ期愈合。所有病例经术后复查效果满意。结果：该组病例在唇裂修复的同期行口、鼻瘘口之完善封闭。结论：此方法适用于单侧重度完全性唇裂且齿槽骨裂隙较宽大者。     

前颌中缝牵张修复牙槽裂的实验研究

目的　探索用缝牵张成骨技术以组织再生的原理修复牙槽裂。方法　采用犬牙槽裂模型 ,牙槽裂形成术后 2周 ,于前颌中缝处安置缝牵张器 ,外张力 2 0 0g。牵张 2～ 3周 ,裂隙侧的前颌骨向侧方移动贴紧远中裂缘 ,用局部黏骨膜瓣修复牙槽裂隙。保持 2周后去除缝牵张器。临床观察、连续X线、头颅干骨和组织学检查评价治疗结果。结果　所有对照动物形成规则的牙槽裂 ,无自发骨性愈合。前颌中缝牵张后 ,裂隙侧前颌缓慢向裂侧上颌靠拢 ,2～ 3周与远中裂缘密切贴合。X线片示前颌中缝呈现由窄渐宽的三角形 ,三角形的尖端指向后方 ,三角区域的骨密度逐渐增加。骨膜成形术后 3个月 ,原牙槽嵴缺损处骨质连续性完全恢复 ,且牙槽骨段在三维方向上均与对侧相同。前颌中缝恢复正常直线形态。结论　该牙槽裂模型稳定性和重复性好 ;前颌中缝牵张诱导缝区新骨形成 ,一侧前颌向裂隙移位和局部骨膜成形可达到完善的牙槽裂修复。     

唇腭裂早期治疗中对患者及其父母的支持

唇腭裂早期治疗是对唇腭裂患儿出生后存在的生理功能障碍、外貌缺陷，以及随生长发育畸形的变化，术后继发的牙颌系统畸形，患儿及父母的精神心理健康问题进行一系列治疗护理，直到成为身心康复的个体，唇腭裂的治疗是长期，复杂的过程，护理是在此系列治疗中针对患者及父母各阶段存在的知识缺乏提供适当的信息，对患者及父母精神心理状况，围手术期的问题，语音异常等进行健康教育，为患儿及父母提供必要的帮助，可取得良好效果。     

上唇短缩畸形的手术治疗

目的 针对微笑时鼻唇部出现上唇上提并短缩,鼻小柱下方褶沟,上唇牙龈外露等现象,探讨一种治疗上唇短缩畸形的手术方法.方法 采用经口或鼻前庭切口,将鼻小柱根部鼻中隔降肌肌纤维切断及部分切除,并广泛剥离使上唇下降.结果 共为27例上唇短缩畸形患者进行手术治疗.其中9例采用了双侧鼻小柱外侧与前庭基底贯穿切口,18例采用了上唇唇龈沟切口.通过手术,患者获得微笑时上唇中部适度降低,鼻小柱下方褶沟变浅或消失,上唇牙龈外露消失的效果.6例患者还在手术矫正上唇动态短缩畸形的同时,实施了鼻整形术.通过手术可矫正鼻唇牙龈部的综合动态缺陷,获得满意的美学效果.结论 手术方法治疗上唇短缩畸形,可改善患者微笑时的表情,是值得推广的治疗方法.     

唇腭裂患者上颌骨牵引成骨术后发音方式的变化

目的:通过对行颅外支架式上颌骨牵引成骨术(rigidexternaldistraction,RED)唇腭裂患者治疗前后的错误发音数量变化、不同发音部位、不同发音方法以及不同类型错误发音发生特点及其变化评价,分析上颌骨RED对患者发音方式的影响。方法:1999年至2001年行上颌骨RED的唇腭裂术后上颌发育不足患者21例,其中男性13例,女性8例,平均年龄15.05岁。所有患者RED前后进行语音测听并分类。治疗前后错误发音的差异性用非参数检验。结果:RED术后42.9%患者错误发音数较RED前增加,19.0%减少,38.1%无变化。从发音部位,舌尖前音错误发音发生率最高,其次为舌面音。从发音方法,错误发音多发于塞擦音。错误发音类型以咽喉摩擦/爆破音为主,其次为腭化构音和声门爆破音。上颌骨RED后腭化构音累及音节数减少,但咽喉摩擦/爆破音和声门爆破音反而增加,尤其是咽喉摩擦/爆破音。结论:唇腭裂患者经RED前移上颌骨后,会对患者发音方式产生影响,在行语音治疗前需考虑全面。

Mid-infrared spectroscopy on skin using a silver halide fibre probe in vivo

Background/aim: Mid-infrared spectroscopy is a versatile method for in vivo investigation of skin after topical treatment with skin care products.
Methods: FTIR-spectrometer (Bruker Optics) with a flexible silver halide fibre probe (Infrared Fiber Sensors).
Results: Absorbance spectra from 700 to 3000 cm⁻¹ have been recorded to gain information about proteins (amide-I and amide-II vibrations at 1650 and 1550 cm⁻¹), esters (1740 cm⁻¹), carboxylic acid (1710 cm⁻¹), polyalcohols (1050 cm⁻¹) and hydrocarbons (CH _n vibrations at 2800–3000 cm⁻¹).
Conclusions: Using the particular light guide, we were able to measure for the first time the effects of lip care products on lips directly. Furthermore, water binding and glycerol content of the skin could be determined simultaneously, as well as the replenishment of lipids by lipid-enriched bath oil.
