Vocal cord swelling benign and malignant, early from the symptoms can not be distinguished, so there is no “precursor” said, vocal cord swelling is generally invisible, need to be observed under the laryngoscope to make a preliminary judgment, such as whether the surface is smooth, whether the border is clear, whether the invasion of the surrounding tissues, etc., and the exact identification also need to be clearly diagnosed through histopathological examination. The exact differentiation also requires histopathologic examination to make a clear diagnosis.
1. Benign vocal fold swellings: The most common benign vocal fold swellings include vocal fold nodules, vocal fold polyps, and vocal fold cysts. The surface of benign swelling is smooth, the boundary is clear, and it does not invade the surrounding tissues and grows slowly.
2. Malignant vocal fold swelling: common malignant vocal fold swelling includes laryngeal cancer, which has rough or cauliflower-like surface, broken surface and foul smell, unclear boundary, and also invades the surrounding tissues and grows faster.
In addition to the above clinical differentiation points, pathologic biopsy is needed to confirm the diagnosis.
Therefore, after the discovery of the swelling, we must consult the doctor as soon as possible, and carry out laryngoscopy and pathological examination to determine the benign or malignant nature of the swelling, benign timely surgical resection, and malignant after surgery, radiotherapy is also needed to avoid the spread of the tumor as soon as possible.
