OBJECTIVETo investigate the correlation between enhanced computed tomography (CT) findings and pathological results of rare parotid gland tumors, and improve diagnosis accuracy.
METHODSThe enhanced CT manifestations of 22 cases with pathologically documented rare parotid gland tumors, which included 6 cases of basal cell tumor, 5 cases of myoepithelioma, 4 cases of vascular invasion, 3 cases of lymphatic cyst, 3 cases of lipoma, and 1 case of chondrosarcoma, were retrospectively analyzed. The location, size, shape, density, and relationship with surrounding structure were evaluated on CT images.
RESULTSThe enhanced CT showed that basal cell tumors occurred in the superficial lobe of the parotid gland, with clear boundary, within the cystic lesion. The lesions were moderate to obviously enhanced, which may be accompanied by enlarged lymph nodes. Myoepithelial tumors were located in the superficial lobe of the parotid gland, with a small cystic prone and microcalcification within a few cases. The lesions were moderate to obviously enhanced. Hemangiomas of soft tissue mass prominent in the parotid gland surface were mild to significantly enhanced. Larger lesions may occupy the entire parotid gland, with uneven density and visible vein stone. The CT density values of the lymphatic cyst were usually higher. Chondrosarcoma mainly manifested cystic mass at the calcification edge. Lipoma with fat density mass exhibited clear boundary without enhancement. Fiber separation could be observed in the lesion.
CONCLUSIONCT can reflect the pathological features of rare parotid gland tumors by demonstrating their corresponding imaging features. Enhanced CT is the most effective means of imaging to identify the nature of rare tumor of the parotid gland lesions.

Objective To perform facial nerve monitoring in patients under the low level of neuromuscular blockade during resection of acoustic neurinomas.Methods Twenty-eight patients with large,or medium acoustic neuroma underwent the surgery of acoustic neurinomas resection. During the operation,TOF and EEG monitoring were performed in order to detect the degree of muscle relaxation and the depth of anesthesia. Neuromuscular relaxation was maintained at T_4/T_1=25%~50% by adjusting doses of muscle relaxant and aneasthetic. Free-run EMG and Triggered EMG of orbicularis oris, orbicularis oculi, masseter and trapezius were recordered to monitor the function of the facial, trigeminal and accessory nerves, respectively. The function of the facial nerve was evaluated at first week and half year postoperatively according to House-brackmann classification.Results The facial never was successfully identified and mapped by neurominitoring in all 28 patients. successfully, tThe electrical stimulation was 0.1 mA-0.3 mA and no any involuntary body movement was observed in all patients ne of patients have moved during operation. The preservation of the facial nerve function following surgery was good. Five patients had a HB grade I, 13 a HB grade II, 8 a grade III and 2 a HB grade IV The facial nerve function was HB Grade Ⅰin 5 of 28 patients, HB GradeⅡ in 13, HB Grade Ⅲ in 8 and HB Grade Ⅳ in 2 immediately after operation. Six months after surgery, 10 casespatents showed demonstrated a HB GradeⅠof facial never function, 12 cases exhibited a slight palsy (HB Grade II) , and 5 cases exhibited a HB Grade III palsy and . Another 1 cases a exhibited severe palsy (HB Grade IV).Conclusions Facial nerve monitoring in patients under the low level of neuromuscular blockade can ensure the surgical safety and preserve the facial never function.
