Most parotid tumors are benign tumors, and the surgical approach is mainly parotidectomy and facial nerve dissection. In order to avoid complications of facial nerve injury and facial muscle paralysis, a long incision is usually required to achieve good exposure of the surgical area. The length of the traditional “S” incision in front of and behind the ear screen is usually more than 16 cm, which leaves obvious surgical scars on the postoperative neck and affects the appearance and quality of life. The most important feature of endoscopic-assisted minimally invasive parotid surgery is that patients no longer have to worry about leaving visible scars on their face after surgery, which can affect their appearance. The new minimally invasive surgical incision is approximately 4.0 cm and is located just below the back of the earlobe. The facial flap is separated using a high-frequency ultrasonic knife under a monitor with the aid of a 5-mm diameter endoscope. The facial nerve trunk was searched for and the cervical or temporal facial trunk was dissected depending on the location of the tumor. The gland is cut about 0.5-1.0 cm lateral to the tumor, and the normal superficial parotid lobe tissue and parotid ducts are preserved as much as possible without sutures and ligatures. In addition, the new minimally invasive surgery routinely preserves the subcutaneous branches of the greater auricular nerve, thus preserving the patient’s earlobe sensation. 3-0 absorbable thread is intermittently sutured under the dermis without removal of sutures; negative pressure drainage is applied without pressure bandaging after surgery, and no other diet is restricted except for an acidic diet. 48-72 h drainage tubes are removed and the patient is discharged on the third to fourth postoperative day. From October 2004 to September 2006, a total of 14 patients hospitalized with parotid masses were operated with endoscopic assistance for parotidectomy. The average operative time was 115 minutes. The surgical procedure included superficial parotidectomy in 3 cases and partial superficial parotidectomy in 11 cases. The postoperative pathological diagnosis was: pleomorphic adenoma in 8 cases, Warthin’s tumor in 4 cases, lymphoepitheliosis in 1 case, and reactive hyperplasia of lymph nodes in 1 case. Postoperative follow-up ranged from 6 to 31 months, with a mean of 14 months. Mild facial nerve palsy occurred in 5 cases, all of which returned to normal within 6 months. No complications such as wound bleeding, parotid fistula and Frey syndrome occurred. All patients were highly satisfied with the concealed surgical incision. Minimally invasive parotid surgery relies on two new medical devices to accomplish this: an endoscopic system similar to laparoscopic surgery, where the monitor and light source provide excellent illumination and magnification for the surgical operation and different tissues are clearly exposed and identified. The difference is that the endoscope is only 5 mm in diameter, the operating cavity is established by manual subcutaneous separation, and no CO2 gas is injected. The second is the use of ultrasonic knife, the principle is that by high-frequency ultrasonic shock, the knife blade contacts the water vaporization in the tissue cells, the protein hydrogen bond is broken, and the tissue is coagulated and cut. The temperature of the ultrasonic knife tip is lower than 80℃, which causes less tissue damage compared with the commonly used high-frequency electric knife. The ultrasonic knife has a strong coagulation function, and the protein coagulation can close and cut off the 3mm diameter blood vessels, avoiding the foreign body of the wire ligated in the wound and making it less likely for salivary fistula to occur after surgery. Endoscopic-assisted parotidectomy is indicated for benign masses in the superficial lobe of the parotid gland, ≤4 cm in diameter. but it is not suitable for patients with malignant tumors of the parotid gland and tumors too large to affect the exposure of the main trunk of the facial nerve, etc. With the rapid development of China’s economy and the improvement of people’s living standards, patients’ requirements for appearance have also increased. Endoscopic-assisted parotidectomy is a small and concealed incision, in line with the principle of minimally invasive surgery, and the patient recovers quickly, making it one of the options for surgery of benign parotid tumors.
