Cleft surgeons are always concerned about the impact of their surgical maneuver on the growth of the maxilla. Hypoplastic maxilla, concaved mid-face and deformed dental arch have constantly been reported after cleft treatments. It is very hard to completely circumvent these postoperative complications by current surgical protocols. In this paper, we discussed the factors that inhibit the maxillofacial growth on cleft patients. These factors included pre-surgical intervention, the timing of cleft palate and alveolae repair, surgical design and treatment protocol. Also, we made a review about the influence on the maxillary growth in un-operated cleft patients. On the basis of previous researches, we can conclude that most of scholars express identity of views in these aspects： early palatoplasty lead to maxilla growth inhibition in all dimensions; secondary alveolar bone graft had no influence on maxilla sagittal growth; cleft lip repair inhibited maxilla sagittal length in patients with cleft lip and palate; Veau＇s pushback palatoplasty and Langenbeck＇s palatoplasty with relaxing incisions were most detrimental to growth; Furlow palatoplasty showed little detrimental effect on maxilla growth; timing of hard palate closure, instead of the sequence of hard or soft palate repair, determined the postoperative growth. Stilt, scholars hold controversial viewpoints in some issues, for example, un-operated clefts have normal growth potential or not, pre-surgical intervention and pharyngoplasty inhibited maxillofacial growth or not.展开更多

Moreover, racial variation for Asian nose rhinoplasty could even demand sophistication of tip and columella strut graft infrastructure enhancement. Various autogenous graft options such as 6th costal cartilage, septal cartilage and conchal cartilage are very commonly considered whilst the 10th costal cartilage is scarcely reported. Objective and Method: The purpose of this manuscript is to illustrate the detailed operative steps to harvest the 10th costal cartilage for infrastructural grafting at NTC subunits by a case illustration. The pros and cons of different cartilage options will be discussed, particularly its application in cleft nose rhinoplasty in Chinese patient. We have adopted the 10th rib as the key option for NTC reconstruction in 11 cases of Chinese cleft secondary rhinoplasty since 2019 and have achieved good and stable results without complications. Conclusion: The 10th costal cartilage is one of the best options in Nasal Tip Columella subunits reconstruction, particularly in complex cleft nose or failure revision aesthetic rhinoplasty cases, due to its safety of harvesting, and the sufficient quality and quantity of grafting materials it provides for simultaneous adjunctive augmentation purpose.展开更多
