Instead

The mosquitoes in the summer night are invincible. Various "human mosquito wars" have been staged in turn, especially when they are sleepy in the early morning, the buzzing sounds are endless.

Recently, Mr. Zhou was asleep at night, and was suddenly awakened by the buzz of mosquitoes in his ear. He waited for the mosquito to approach himself, and slapped his hand and threw his left ear. But the mosquito was not killed, but Mr. Zhou felt that the left ear was severe because of his hard work, and even the sound he heard was dull and tinnitus.

On the morning of the next day, Mr. Zhou went to the otolaryngology head and neck surgery of the Aerospace City Hospital of Xi'an People's Hospital (Fourth Hospital of the City). Left ear), conductive hearing decreased. After getting the results of the inspection, Mr. Zhou was helpless and joked again and again.

According to the doctor, the perforation of the trauma is a vibration wave and airflow when the drum film encounters an external air vibration (such as palm, firecrackers, explosions, etc.), and it quickly spreads to the outer ear canal to rupture the tympanic membrane. The human body will suddenly feel ear pain, hearing, and tinnitus immediately, a small amount of bleeding from the outer ear canal, and the stuffy inner ear stuffy. It may also be damaged in the inner ear due to the strong exercise of the bones in the small bones, and dizziness, nausea and mixed deafness occur.

The human tympanic membrane is divided into three layers, and it is divided into epithelial layers, inherent layers (fiber layers), and mucosal layers from the outside to the inside. Because the inherent layer in the middle does not have the ability to regenerate, there are only two layers after the self -healing: the epithelium layer and the mucous membrane layer. Therefore, the neonatal tympanic membrane after healing is thinner than the normal tympanic membrane. Generally speaking, the perforation is small, the self -healing rate of the tympanic membrane is higher; the larger the perforation, the smaller the self -healing rate of the tympanic membrane. If there is no secondary infection, most tympanic membrane perforation can heal itself within 1 month.

According to the inspection, consider Mr. Zhou's left ear drum film, and the possibility of healing itself is small. It is recommended to hospitalize surgery. Yang Yongtong used ear endoscopy to complete the tympanic repair in 30 minutes. Mr. Zhou was discharged normally the next day. Three weeks after surgery, the ear endoscopy and pure sound inspection were reviewed. Mr. Zhou's hearing was completely returned to normal.

The doctor reminded that once the perforation of the drum membrane caused by external forces should go to the hospital in time, the doctor made a judgment, and the ear endoscopy and hearing evaluation should be performed if necessary. Keep the ear canal clean during the tympanic recovery process, do not get into the water, and keep the outer ear canal dry.
