Eardrum surgery mostly refers to tympanoplasty, the use of gelatin sponge in the inner side of the tympanic chamber is usually absorbed in 10 to 15 days, but also varies from person to person, and some patients take slightly longer. Some gelatine sponges in the external auditory canal are dissolved and discharged, while others need to be removed by the surgeon about 3 weeks after surgery.
Gelatin sponge is often used in eardrum surgery to fill in the tympanic cavity and support the graft. Glands in the tympanic cavity can secrete mucus, and inflammatory secretions are also exuded after surgery, which can infiltrate the gelatin sponge in the early postoperative period to support the graft, so that it can be adhered to the mucous membrane of the grafting bed, and to promote the growth of the two to bridge the gap. The gelatin sponge can be diluted and discharged through the Eustachian tube at 10-15 days after surgery.
The gelatine sponge in the external auditory canal contacts the skin tissue and presses the tympanic membrane against the graft to promote healing. Some of the gelatin sponges dissolve and are expelled, while others need to be removed by the surgeon about 3 weeks after surgery.
Patients who have undergone eardrum surgery with gelatin sponges in the ear should follow the surgeon’s instructions for standardized medication, regular checkups, and prompt medical attention if they experience any discomfort.
