The three-year-old girl Amina Khan, who was born in the Hetian area of ​​Xinjiang, was born with upper and lower gums. He never opened his mouth and could only feed through the gap between the upper alveolar and his nose. She survived. After the unsuccessful visit to the hospital, the family held her in Guangzhou recently. With the help of 3D printing technology, Guangzhou doctors successfully separated the gums for her, and Amina Khan finally opened her mouth like a normal child.
Rare malformations no more than 100 cases worldwide
The face of Amina Khan has a severe deformity: the deformed fusion of the upper and lower jaw molar areas, and the upper and lower gums cannot be opened together. At the same time, she also suffers from cleft lip and palate, soaked in water, through the natural cracks in the upper lip, the whole piece swallowed, is her main source of nutrition after birth.
According to Cui Yingqiu, director of the Oral and Maxillofacial Surgery Department of Guangzhou Women and Children's Medical Center, there is no documented record of the integration of maxilla and mandible in China. There are only 100 cases recorded in foreign countries.
In the past three years, Amina Khan has never opened his mouth and he has never chewed any food. His speech is also vague. Due to the complicated condition, many hospitals in my hometown are unable to diagnose and treat it.
The People's Daily reporter interviewed in southern Xinjiang discovered Amina Khan and went to the Affiliated Hospital of the local medical university for medical treatment. Later she was referred to major hospitals in Beijing and Shanghai for medical treatment and contacted China Lips through the Randolph Fund. Cleavage diagnosis and treatment alliance.
According to a multi-faceted expert consultation conducted by the China Cleft Lip and Palate Diagnosis and Treatment Alliance, Amina Muhan’s surgical risk was high and he eventually recommended surgery at the Guangzhou Women and Children Medical Center.
Perform 2 3D simulations before surgery
The skeletal condition in the mouth of Amina Wooden Khan is complicated and the naked eye cannot observe it at all. The Oral and Maxillofacial Surgery Department of Guangzhou Women and Children's Center decided to perform surgery on Amina Khan with digital surgical simulation technology and 3D printing technology.
Cui Yingqiu introduced a 3D printing company that provided technical support to model the maxillofacial of Amina Khan on a computer and printed out two 1:1-sized 3D models using resin.
Before the actual surgery was performed on Thursday, the surgical team performed a virtual surgery on the computer and performed a second simulated operation on the 3D model to ensure that nothing was lost.
Cui Yingqiu introduced that during the operation, a 30mm x 6mm to 8mm bone was cut off from the right fusion site of Amina Khan so that her upper and lower teeth can be separated. There are also two required osteotomies on the left side. The doctor also creatively implanted her own periosteum on the bone wound to avoid postoperative recurrence of adhesions.
After successfully completing the operation, Amina Khan finally opened her mouth like a normal child. According to reports, Amina Wood Khan can be discharged home after 4 days, but it also requires the repair of cleft palate and micromaxillary deformity. In addition, long-term correction and training are needed after the operation to restore language, chewing and swallowing functions. She is expected to have a neat tooth like a normal child, and she can't even see the difference.
