Now, with the popularization of medical knowledge, we know that children snoring has many hazards, such as: 1, children sleep at night snoring, especially the loud and serious snoring, sleep often interrupted breathing, night does not get a good rest, daytime spirit, poor appetite, so that the intake of food calories is not enough, over time, resulting in children’s growth stagnation, height, weight will be lower than the normal children of the same age. 2.Lack of concentration in class during the day, drowsiness, memory loss, and poor academic performance. 3. Children’s night waking, sleepwalking and urine loss are also related to snoring. 4. Long-term open-mouth breathing may also affect the development of the jaw and face, forming a special face, the so-called “adenoid face”, which is characterized by an upturned upper lip, bared upper teeth, high palatal arch, and a dull expression. 5. The blockage of the upper airway of children is likely to lead to sinusitis or otitis media, and the recurrent attacks will not be cured after a long time. 6. Long-term snoring not only affects the normal physical and intellectual development of children, but also causes jaw deformity and abnormal craniofacial bone development, and in serious cases, it can also cause abnormal development of the sternum and funnel chest. Some time ago, a child with severe snoring was admitted to our department. He had been snoring severely since he was 2 years old, and his airway was blocked during sleep inspiration, resulting in a negative pressure depression in the chest cavity, and was found to have adenoid hypertrophy and tonsillar hypertrophy blocking the upper airway in some large hospitals. The doctor advised the parents of the child to have the tonsils and adenoids removed when the child is older, but at present it is too small and the operation is risky. Therefore, the parents waited until the child was 4 years old before coming to our hospital for treatment. After our examination, we found that the child’s symptoms were already more severe, his development was significantly smaller than that of children of the same age, and his thorax was funnel-shaped. We recommended that the child be operated as soon as possible (in our department, after weighing the pros and cons and fully communicating with the parents, plasma adenoid tonsillectomy has been performed on children around 2 years of age, as these children’s enlarged tonsils and adenoids have caused serious complications.) We performed plasma adenotonsillectomy on the child after the parents’ consent. The child’s severe thoracic depression during sleep disappeared 3 days after surgery, although there was still some snoring, which was due to postoperative pharyngeal cavity edema at that time and would be further relieved 2 weeks after surgery. Funnel chest is a congenital and often familial condition. It is a deformity in which the sternum, rib cartilage, and part of the rib cage are depressed toward the spine to form a funnel shape. The cause of funnel chest is unknown and is thought to be genetically related. Funnel chest is a progressive lesion that may be present at birth, but often becomes more pronounced after a few months or even years and is detected by parents. The external appearance is characterized by a sunken anterior chest, anteriorly extended shoulders, a slight hunchback and a prominent epigastrium. This is probably due to the compression of the heart and lungs by the funnel chest and scoliosis, which impairs the respiratory and circulatory functions, resulting in a shorter survival time and death before the age of 40. Currently, the treatment of funnel chest is based on surgical correction of thoracic deformity. Our clinical observation is that some children with funnel chest have sleep apnea syndrome caused by tonsillar and adenoid hypertrophy in infancy and childhood, and the upper airway is blocked at night. Or the child has a tendency of congenital deformation of the thorax, and snoring accelerates the deformation of the thorax. For such children, we believe that the upper airway stenosis should be lifted first, and plasma adenotonsillectomy is a minimally invasive and safe procedure for children over 2 years old. Removal of the upper airway stenosis can effectively cure the funnel chest or alleviate the progression of the funnel chest.
