As the Chinese New Year approaches, people, especially young people, can’t hold back their joy and get ready to set off firecrackers and fireworks to relax after a long year of hard work and to add to the festive atmosphere. Every year during the Chinese New Year, hospitals receive patients with blast deafness caused by firecrackers. The common feature of these patients is that they feel a vague pain in their ears after setting off more powerful firecrackers and are unable to hear the sound. The so-called blast deafness, also known as noise deafness, refers to the acute damage to the auditory organs caused by the sudden occurrence of loud sounds. Due to improper protection or lack of necessary protective equipment, the shock wave acts directly on the auditory organs and causes acute and severe trauma, resulting in rupture of the tympanic membrane, destruction of the middle ear bone, and damage and bleeding of the inner ear tissue. Immediately after the shock, both ears feel deaf, tinnitus, ear pain and other symptoms can be diagnosed as blast deafness. Severe cases may also be accompanied by vertigo, vomiting, and other symptoms of inner ear damage. Hearing tests may reveal severe hearing impairment or even complete hearing loss. In mild cases, hearing can be partially restored with timely treatment, while in severe cases, permanent deafness can result. During the Chinese New Year, the noise generated by firecrackers can be as high as 90 decibels or even more than 100 decibels. Although the deafening sound of firecrackers adds to the festive atmosphere, the harm caused by the powerful noise is multifaceted, the first is hearing damage, which can cause acute blast deafness. When the noise intensity greatly exceeds the tolerance limits of the human ear, it can cause permanent hearing damage to many people, especially children. In general, the more firecrackers are set off, the more concentrated the time and the louder the sound, the more chances of causing deafness and the more severe the hearing damage. In individually sensitive individuals, even one occasional discharge or hearing others discharge firecrackers once in close proximity can cause deafness. The clinical treatment principles of blast deafness are: 1: isolate the noise stimulation to avoid re-injury; 2: timely application of hormones, vitamins, neurotrophic drugs, improving microcirculation and pro-cellular metabolism drugs treatment, if possible, can simultaneously assist hyperbaric oxygen chamber treatment; 3: for patients with tympanic membrane perforation to prohibit ear drops and water in the ear, and avoid blowing nose, cold-induced secondary infection, use antibiotics as appropriate; 4 : If accompanied by traumatic brain injury or injury to other parts of the body are treated according to the situation, such as trauma disposal. The only way to effectively prevent the emergence of blast deafness is to have as few or no firecrackers as possible during the holiday season. When setting off firecrackers, take precautions by opening your mouth while covering your ears with both hands or stuffing cotton balls in both ears to stop the noise from vibrating your eardrums to the maximum extent possible. In case of ear pain, tinnitus and deafness after the explosion, go to the otolaryngology department of a regular hospital and seek treatment under the guidance of a specialist to save your hearing as much as possible.
