Myringoplasty is an operation performed to repair a perforation of the tympanic membrane. The ear is usually free from discharge with no other anatomic or physiologic defect. This operation, therefore, offers the best opportunity to study skin grafting procedures in the middle ear since the number of variable factors is limited. The purpose of this paper is to review the principles of myringoplasty and compare the results using full-thickness postauricular skin, split-thickness arm skin, and ear canal skin.
Blood Supply of the Ear Canal and the Tympanic Membrane
This subject was reviewed in detail in a previous publication1 and will be summarized here. The blood supply of the external canal is different in its cartilaginous and bony portion. The vessels of the cartilaginous portion of the canal stop abruptly at the bony isthmus except in the posterior superior portion, where they run in the substance of the skin down
