There is a legend in South America that every child with a cleft lip is an angel sent from heaven to the mortal world. They experience a surgical repair that makes him whole before they even know the world. But this is not the end of the pain …… After cleft lip repair, as the child grows and develops, new deformities of varying degrees of lip and nose usually appear, and some deformities do not stabilize until development stops, so further deformity revision surgery is often required. These deformities are mainly manifested in lip and nasal deformities: such as scar deformity of the upper lip, uneven lip redness, non-display of the human middle, too long upper lip, too tight upper lip, whistle-like deformity, nasal wing collapse, too small nostrils, etc. The secondary deformities of the mouth and nose often lead to low self-esteem and reluctance to interact with others, which may even affect their schooling, employment and marriage. At an age when they should be youthful and lively, but because they are children with cleft lip, they become silent, introverted, have low self-esteem, afraid of contact with people, afraid of others seeing their asymmetrical nose, mouth and lips that cannot be closed, and want to isolate themselves from people …… What poor innocent children these are, because the congenital cleft lip has changed their life, and their parents, because of their Their parents, because of their guilt and heartache for their children, live a more painful life. Therefore, the second stage of post-operative revision of cleft lip becomes especially important. If the deformity is obvious, we advocate a revision before school age because the patient is too young to fundamentally resolve the deformity, and some deformities, although corrected, may appear again with development. This surgery is mainly a psychological treatment to prevent the child from being ridiculed and discriminated by classmates at school due to the deformity, which may affect the normal psychological development of the child. When the child’s development is complete, a more thorough and definitive second-stage cleft lip surgery can be performed. This includes: 1. correction of nasal deformities, such as nasal collapse and low nasal dorsum; 2. correction of upper lip deformities, such as lip scar, over-long upper lip, over-short upper lip, over-tight upper lip, abnormal upper lip orbicularis muscle, uneven lip redness, whistling deformity, etc. After the second-stage cleft lip revision, children who were introverted and shy when they came to see me became more cheerful and confident, and they started to take the initiative to communicate with others, to touch things they once dared not think about, and to look at the world with eyes full of hope and love. It can be said that the second stage of cleft lip surgery is an important turn in the life of a cleft lip child, because of it, they welcome the late happiness in their life, and the angel smiles again.
