Tympanoplasty with antrostomy or mastoidectomy (without reconstruction of the ossicular chain)

A tympanoplasty is an outpatient surgery to correct a tear of the eardrum (the eardrum is the tissue found in the middle part of your ear and divides your inner ear canal). A mastoidectomy is surgery to remove the cells in the hollow and air-filled spaces that are in the skull behind the ear, which are called mastoid cells, while an antrostomy consists of opening the maxillary sinuses through an incision made under the upper lip, in the gum, reaching the breast through a small window, open in the bone itself.
