After treatment with standard medication and surgery, the child’s hearing gradually returned to normal. The treatment plan] Topical medication (physiological sodium chloride solution) + oral medication (nasal abdomen and orifice granules) + adenoidectomy + tympanic membrane puncture and aspiration [Treatment period] Half a month of hospitalization [Treatment effect] The child’s hearing returned to normal I. Initial consultation The child, male, 4 years old, visited our hospital for “hearing loss for half a year, aggravated for 1 week”, and asked the family about the onset of the child’s illness in detail. One week ago, the child complained of hearing loss after catching a cold, so the child was brought to our hospital. On examination, the child’s external auditory canal was found to be clear, with no secretions, the tympanic membrane was sunken, the light cone was shortened, the tympanic membrane was amber in color, the hearing test indicated conductive hearing loss, the average hearing threshold was 40 decibels, and the B-shaped curve of sound conduction resistance. The diagnosis was “pediatric secretory otitis media and adenoid hypertrophy”. The child’s middle ear was inflamed due to adenoid hypertrophy, and both of them required intervention. The child was given physiological sodium chloride solution to cleanse the nasal cavity, while oral administration of nasal abnormalities and orifice granules to improve nasal ventilation. The child was also hospitalized for adenoidectomy to remove the hyperplastic adenoids because of their obvious enlargement and hypertrophy. Tympanic membrane aspiration was performed on both ears. After the adenoids were removed and treated with medication, the child’s nasal ventilation was initially restored. After the tympanic membrane puncture and fluid extraction treatment, the child’s hearing was significantly improved. After half a month of standard treatment, the child’s hearing returned to normal and he was discharged from the hospital. Precautions We are glad that the child’s condition has improved and his hearing has recovered. If there is any discomfort in the child’s ear or other parts of the body, do not ignore it and bring the child to the hospital in time to improve the relevant examination and standardize the treatment to avoid delaying the disease. Pay attention to the protection of the external ear canal in daily life to avoid the recurrence of middle ear inflammation caused by pollutants entering the ear, participate in more outdoor sports, ensure balanced nutrition, and get enough sleep to help develop a healthy body. V. Personal insight In daily life, any abnormal performance of children should attract parents’ attention. In this case, the child’s hearing decreased for half a year, and the parents brought him to the clinic only after his condition worsened. The onset of otitis media is insidious, but it must be actively treated after diagnosis. Since the nose and ears are connected, medication often includes drugs for the nose. If medication is not effective or if the condition is severe, surgical treatment, such as adenoidectomy, tympanocentesis, tympanic membrane placement, etc., can be considered.
