There is no one who does not care about his or her face, but ENT head and neck surgeons are always stepping on the tightrope of the facial nerve, which is responsible for the face, and the parotid surgery is the most closely related to the facial nerve. The parotid nerve enters the parotid tissue from the stoma below the earlobe and divides into two and then five branches that fan out into the facial expression muscles from the forehead to the neck, and the preferred treatment for swelling in the parotid gland is surgery, so parotid surgery is not really about making a tumor, but about dissecting and protecting the facial nerve. The thicker the facial nerve is near the earlobe, the better the resistance to pulling and separation is compared to the endings, so it is very important to find the facial nerve for parotid surgery. The first technique of parotid surgery was introduced into China from abroad from the center to the endings, but later Chinese doctors found that finding the endings in a shallower position is less difficult, so there are now 2 ways to find the endings in China, the parotid surgery is performed both in the downstream and the retrograde way. In conclusion, as long as one is familiar with the alignment of the facial nerve in the parotid gland and the nerve is not invaded by the tumor, it is possible to remove the tumor and protect the face at the same time.
