Mixed tumors of the parotid gland, also known as pleomorphic adenomas, are benign tumors that occur in the parotid gland. Mixed tumors of the parotid gland are one of the most common tumors of the oral and maxillofacial region. It occurs mostly in young adults, usually without obvious conscious symptoms, and grows slowly and can last for several years or even decades. The lump is located in front of or below the earlobe and grows slowly, with a nodular elevation on the surface, no tenderness, soft or hard to the touch; some parts are soft like a sac, some parts are hard like a bone, and the shape is irregular and can be pushed. Otherwise, it will be more difficult to operate when the tumor grows larger, especially when the tumor is close to the facial nerve, and it is very difficult to preserve the facial nerve and remove the tumor completely. The main treatment method for mixed tumors of the parotid gland is to remove the tumor completely by surgery and to protect the facial nerve during surgery. The facial nerve is an important nerve that manages facial movement and expression, and plays an important role in facial appearance. Once it is damaged, facial palsy may occur in different degrees, such as loss of ipsilateral frontal lines, incomplete eyelid closure, cheek puffing, and crooked mouth. Since the envelope of the tumor is often incomplete, sometimes the tumor cells may invade the envelope or extra-envelope tissues, which may lead to recurrence of the tumor if the resection is not complete. Therefore, the tumor should be removed together with the surrounding parotid tissue during parotid tumor surgery. In the past, superficial lobe, deep lobe or whole lobe resection of parotid gland was used according to the location of the tumor, and the facial nerve was preserved. Superficial or total lobectomy of the parotid gland requires dissection of the branches of the facial nerve and the common trunk, which greatly increases the incidence of postoperative temporary facial paralysis. At the same time, because the surgery destroys most of the parotid fascia covering the surface of the parotid gland, a natural mechanical barrier between the parotid tissue and the skin is lost, and the incidence of gustatory sweating syndrome is more pronounced in postoperative patients, manifested by flushing and sweating of the skin in the operated area during eating. Superficial or total parotidectomy usually does not preserve the parotid ducts, which often results in atrophy of the parotid gland tissue and greatly diminishes parotid function after surgery. In addition, the facial depressions of patients after superficial or total parotidectomy are also serious, and patients are often not satisfied with the postoperative facial appearance, sometimes requiring transfer of adjacent muscle tissue to fill the depressions, which can add new surgical trauma and affect the function of adjacent muscle tissue. In recent years, based on a large number of clinical case follow-ups and basic research by domestic and international colleagues, we have adopted a surgical approach of partial parotidectomy including the tumor to treat benign tumors such as mixed tumors of the parotid gland. This procedure has significant advantages in reducing facial nerve injury, reducing the occurrence of gustatory sweating syndrome, preserving some parotid functions and reducing postoperative facial depression deformity. A large number of case follow-up studies have also confirmed that the treatment results are consistent with previous procedures in terms of tumor recurrence. Of course, performing partial parotidectomy requires a surgeon with extensive experience and excellent surgical skills, because if the tumor is incorrectly incised, it will lead to recurrence of the tumor and make the later surgery difficult. As for the incision of parotid surgery, the conventional “S” shaped incision often results in a more obvious surgical scar in the upper neck below the earlobe, which is not expected to be satisfactory for young women or patients with facial aesthetic requirements. Therefore, for this group of patients, we were the first in China to perform parotid surgery using the cosmetic incision of facial wrinkle surgery (i.e., the incision is located in front of the ear, in the fold behind the ear, and in the hairline under the ear), and because the postoperative scars are located behind the ear and in the hairline under the ear, they are very hidden and meet the patients’ cosmetic requirements for the surgical incision. In addition, we routinely protect and preserve the greater auricular nerve, which manages the sensory function of the earlobe, throughout the parotid surgery, thus avoiding the complication of earlobe numbness caused by parotid surgery. In conclusion, for benign tumors such as mixed tumors of the parotid gland, our current routine procedure is partial parotidectomy including the tumor. By using special treatments such as cosmetic incision, protection of the greater auricular nerve, preservation of the glandular function, and preservation and immediate restoration of the facial appearance of the operated area, we can achieve a balance of tumor treatment, scar reduction, function preservation, and restoration of the appearance, thus obtaining the ideal treatment results.
