Nasolabial deformities after cheiloplasty Secondary Nasolabial Deformities
Why ? • Serious deformities • Unbalance of facial growth • Error in operation • Shortcoming of operation design • Infection and Split open
Timing of Operation • Facial growth have finished • avoid to disturb facial growth • maintain stability of healing effect
Clinical sign • Shorten or lengthen of upper lip height • Shorten or extension of upper lip width • Deformities of vermilion • Deformities of nose • Scar
Shorten or lengthen of upper lip height nose base lip peak
Clinical sign • Shorten or lengthen of upper lip height • Shorten or extension of upper lip width • Deformities of vermilion • Deformities of nose • Scar
Shorten or extension of upper lip width right cheilion left cheilion
Clinical sign • Shorten or lengthen of upper lip height • Shorten or extension of upper lip width • Deformities of vermilion • Deformities of nose • Scar
Clinical sign • Shorten or lengthen of upper lip height • Shorten or extension of upper lip width • Deformities of vermilion • Deformities of nose • Scar
Big nostril Inclined nose columella Collapsed nose ala
Small nostril Inclined nose columella Collapsed nose ala
Clinical sign • Shorten or lengthen of upper lip height • Shorten or extension of upper lip width • Deformities of vermilion • Deformities of nose • Scar
Anesthesia • General :hard cooperation complicated • Local :good cooperation simple
Preparation of operation • Body:blood test、x-ray of chest • Local:no rash and inflammation
Operation method • Suspending of nose ala • “V-Y”plasty • “Z”plasty
How to avoid secondary nasolabial deformities • Good design of operation • Skillful operation • Good nursing
Embryogenesis Maxillary process Frontonasal process Maxillary process Medial nasal process Medial nasal process Secondary palatal process Secondary palatal process Primary palatal process Palate
Hereditary factors Etiology Environmental factors
Muscle • Palatopharyngeus muscle • Palatoglossus muscle • Levator veli palatini muscle • Tensor veli palatini muscle • Uvula muscle
Clinical Classification • Cleft of soft palate • Incomplete cleft palate • Unilateral complete cleft palate • Bilateral complete cleft palate • Other (Obsolete cleft palate, Congenital fistula…)
Clinical features • Abnormal morphology • Dysfunction of suck • Hypernasality and nose emission • Bad oral hygiene • Malocclusion • Hearing loss • Dysfunction of maxillary growth
治疗原则 综合序列治疗: 外科手术,正畸治疗, 缺牙修复,语音训练,心理治疗等
目 的 • 整复腭部的解剖形态;恢复腭部的生理功能,重建良好的“腭咽闭合”,为正常吸吮、吞咽、语音、听力等生理功能创造条件。
手术要求 • 封闭裂隙 • 将移位的组织结构复位 • 将分裂的肌纤维复位后准确对位缝合 • 减少手术创伤 • 妥善保留与腭部的营养和运动有关的血管、神经和肌的附着点 • 术后的软腭要有适当长度、相当高度以及灵活的动度 • 手术方法简便 • 确保患儿安全
手术年龄--有争议 • 1~2岁为最佳年龄 • 语音发育尚未形成 • 但因手术创伤影响上颌骨发育
术前准备 • 体格检查:生长发育、体重、营养状况、心、肺、有无其它先天性畸形及上呼吸道感染等全身器质性疾患。 • 实验室检查:胸片、血常规、出凝血时间、EKG、听力 • 胸腺肥大——术前三天口服激素 • 口腔颌面部炎症——预先治疗 • 扁桃体过大——摘除 • 保持口鼻腔清洁,清除病灶
麻醉选择 全身麻醉,气管内插管
