It is universally acknowledged that correction of a cleft lip nasal deformity continues to be a difficult problem. In developing countries, it is common for patients with cleft lip deformities to present in their early or late teens for correction of severe secondary lip and nasal deformities retained after the initial repairs were carried out in infancy or early childhood. Such patients have never had the benefit of primary nasal correction, orthodontic management, or alveolar bone grafting at an appropriate age. Along with a severe nasal deformity, they present with alveolar arch malalignments and anterior fistulae. In the study presented here, a strategy involving a complete single-stage correction of the nasal and secondary lip deformity was used. In this study, 26 patients (nine male and 17 female) ranging in age from 13 to 24 years presented for the first time between June of 1996 and December of 1999 with unilateral cleft lip nasal deformity. Eight patients had an anterior fistula (diameter, 2 to 4 mm) and 12 patients had a secondary lip deformity. An external rhinoplasty approach was used for all patients. The corrective procedures carried out in a single stage in these patients included lip revision; columellar lengthening; repair of anterior fistula; augmentation along the pyriform margin, nasal floor, and alveolus by bone grafts; submucous resection of the nasal septum; repositioning of lower lateral cartilages; fixation of the alar cartilage complex to the septum and the upper lateral cartilages; augmentation of nasal dorsum by bone graft; and alar base wedge resections. Medial and lateral nasal osteotomies were performed only if absolutely indicated. The median follow-up period was 11 months, although it ranged from 5 to 25 months. Overall results have been extremely pleasing, satisfactory, and stable. In this age group (13 years of age or older), it is not fruitful to use a technique for nasal correction that corrects only one facet of the deformity, because no result of nasal correction can be satisfactory until septal deviations and maxillary deficiencies are addressed along with any alar repositioning. The results of complete remodeling of the nasal pyramid are also stable in these patients because the patients' growth was nearly complete, and all the deformities could be corrected at the same time, leaving no active deforming vector. These results would indicate that aesthetically good results are achievable even if no primary nasal correction or orthodontic management had been previously attempted.
唇裂鼻畸形的矫正一直是个难题,这是举世公认的。在发展中国家,唇裂畸形患者常在青少年早期或晚期前来矫正婴儿期或幼儿期初次修复后遗留的严重继发性唇鼻畸形。这类患者从未在合适年龄接受过一期鼻矫正、正畸治疗或牙槽骨植骨。除了严重的鼻畸形,他们还伴有牙槽弓排列不齐和前瘘。在本研究中,采用了一种涉及鼻和继发性唇畸形完全一期矫正的策略。在本研究中,26例患者(9例男性,17例女性),年龄在13至24岁之间,于1996年6月至1999年12月首次因单侧唇裂鼻畸形前来就诊。8例患者有前瘘(直径2至4毫米),12例患者有继发性唇畸形。所有患者均采用鼻外整形手术入路。这些患者一期进行的矫正手术包括唇部修复;鼻小柱延长;前瘘修复;通过植骨对梨状缘、鼻底和牙槽进行增宽;鼻中隔黏膜下切除术;下外侧软骨重新定位;鼻翼软骨复合体固定于鼻中隔和上外侧软骨;通过植骨增高鼻背;以及鼻翼基底楔形切除术。仅在绝对必要时才进行鼻内侧和外侧截骨术。中位随访期为11个月,范围为5至25个月。总体结果非常令人满意且稳定。在这个年龄组(13岁及以上),使用仅矫正畸形一个方面的鼻矫正技术是没有成效的,因为在解决鼻中隔偏曲和上颌骨发育不足以及任何鼻翼重新定位之前,鼻矫正的结果都不会令人满意。这些患者鼻锥体完全重塑的结果也很稳定,因为患者的生长已基本完成,所有畸形都可同时矫正,不存在活跃的致畸形因素。这些结果表明,即使之前未尝试过一期鼻矫正或正畸治疗,也能获得美观的良好效果。
