On a long-term basis, the epithelium of pectoralis major flaps incorporated in the mouth and the oropharynx is macroscopically and microscopically very similar to the sourrounding mucosa. Light microscope and electro microscopic investigations show that the type of keratinization of the epithelium of this flap has changed from orthokeratosis to parakeratosis which is typical for the mucosa of the mouth. The possible reasons for these changes, which, to our knowledge, have not been described before, are discussed.
从长期来看，纳入口腔和口咽的胸大肌皮瓣的上皮在宏观和微观上与周围黏膜非常相似。光学显微镜和电子显微镜研究表明，该皮瓣上皮的角化类型已从正角化转变为口腔黏膜典型的不全角化。据我们所知，这些变化的可能原因此前尚未见报道，本文对此进行了讨论。
