Hunan Daily, August 14 (Text/Video Hunan Daily All-Media Reporter Zhou Yangle Correspondent Peng Xiangyue Li Baoqi Lai Ying) The reporter learned today from the Hunan Children's Hospital that the hospital successfully performed mandibular distraction osteogenesis surgery on a 7-year-old boy with micrognathia syndrome, turning the boy with a "bird-beaked face" into a handsome boy.
7-year-old Mumu and his younger brother are twins. When they were born, they were found to have short and retracted chins. They were prone to vomiting when eating, and sometimes choking and coughing. It was difficult for them to chew meat and swallow larger food, so their height and weight were always lower than their younger brother. As they got older, Mumu began to breathe with his mouth open and snore. His mother found that Mumu's chin was getting more and more retracted, and he was getting "uglier" and looked like he had a "bird's beak". After being transferred to the Department of Otolaryngology and Head and Neck Surgery of Hunan Children's Hospital, Mumu was diagnosed with micrognathia, as well as enlarged tonsils and adenoids. He was recommended to be hospitalized for surgery.
It is reported that micrognathia syndrome is caused by various reasons during fetal development, which leads to tongue prolapse and developmental defects of laryngeal tissues due to insufficient mandibular development, resulting in breathing and feeding difficulties. The severity of symptoms varies with the degree of deformity. Severe cases may lead to suffocation and death. The main appearance feature is that the lower jaw of infants and young children is relatively small, presenting a "bird-like face".
In order to solve Mumu's mandibular deformity and adenoids and tonsils at the same time, Professor Zhao Sijun and Professor Huang Min of the Department of Otolaryngology and Head and Neck Surgery of Hunan Children's Hospital convened doctors in the department to discuss Mumu's condition repeatedly, and conducted a full evaluation with experts from the Department of Radiology and Anesthesia and Surgery, and recommended bilateral mandibular distraction osteogenesis + adenoids and tonsillectomy for Mumu. In order to ensure the accuracy of the operation, the expert team of the key laboratory of orthopedics of the hospital simulated the design of osteotomy and lengthening plan through computer software before the operation, and verified the computer simulation results through 3D printing head mold, 3D printing individualized osteotomy module, and pre-bend extender to ensure the accuracy of osteotomy and extender placement during the operation.
After more than 4 hours of joint efforts, the surgical anesthesia team successfully completed the operation. After more than ten days of mandibular traction, Mu Mu's "bird beak" deformity was significantly improved, and his snoring and mouth breathing also improved. He can finally sleep peacefully.
Huang Min introduced that mandibular distraction osteogenesis is currently only performed in a few hospitals in China. Hunan Children's Hospital has performed the operation on many patients since 2020. The youngest was 28 days old and weighed only 2.7 kg. The operation can not only improve the child's breathing and feeding difficulties, but also improve the child's maxillofacial problems and restore his appearance.
