The swelling of the child’s ear is considered to be chondromalacia, which is often caused by external impact on the patient’s ear, or by squeezing or repeated rubbing. In terms of treatment, it is important to actively reduce inflammation, as auricular chondromalacia is particularly likely to cause necrosis of the auricular cartilage, leading to deformation of the ear. In clinical practice, antibiotics need to be administered in a sedative drip, more commonly cefoperazone injection and cefuroxime sodium injection, all of which need to be skin tested before use. Patients can also apply Bactroban ointment, Denide cream, and Ketoconazole cream on the surface of the ear, which can effectively play an anti-inflammatory and anti-swelling role. During this period, if the patient’s pain is particularly pronounced, he or she can also take oral ibuprofen capsules or ibuprofen suspension for pain relief. Be sure not to squeeze the ear again to avoid aggravating the condition. After about a week of active treatment, the patient’s condition should improve significantly.
