The authors presented their experiences with many volunteer cleft lip and palate trips to third world countries; however the structure of this article is not a new hypothesis and data based to support a scientific study, but observations are objective to get a conclusion. To perform one-stage definitive repair of the cleft lip and palate in late-presented patients was the reality that they had only 1 chance to undergo these operations. According to the terms and conditions of this challenging operation, one-stage simultaneous repair of cleft lip and palate is a more demanding and time-consuming procedure than is isolated cleft lip repair or cleft palate repair. Although technically challenging, single-stage repair of the whole deformity in late-presenting patients is a feasible, reliable, successful, and safe procedure in authors' experience.
The maxilla is the most important bony structure of the midface, extending between the zygomatic bone, the orbit, and the upper teeth, which is like a six-walled pyramide. It is vulnerable to midfacial trauma because of the buttresses that extend around the bone and inside there is a sinus contains 2-4 mL of air. Midfacial tissue losses caused by trauma or oncological resections of skin, soft-tissue, and bone may not be life-threatening, but can have
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
