“…This finding may have been related to the high false‐negative rate for mucoepidermoid carcinoma cases (57.1% [4 of 7]) and the small sample size for malignant lesions (7.3% [16 of 218]). Low‐grade mucoepidermoid carcinoma can be misdiagnosed as chronic sialadenitis, a mucous retention cyst, a Warthin tumor, or adenomatoid hyperplasia of the mucous salivary gland 10 , 17 . For further evaluation, a larger study may be required.…”

“…Malignant tumors are typically irregularly shaped, firm, ill-defined and poorly movable, and show fast growth; however, for certain painless, slow-growing tumors of the parotid gland, the possibility of malignancy cannot be easily ruled out (30,31). In previous studies, the accuracy of fine-needle aspiration biopsy in the diagnosis of parotid gland tumor prior to surgery ranged from 91 to 98% (32)(33)(34)(35). There were some misdiagnoses in pathological examination among the preoperative fine-needle aspiration biopsy specimens, intraoperative frozen sections, and paraffin-embedded sections (31,32,36,37).…”

Abstract. Non-standardized or conservative procedures are employed when parotid tumors involving the facial nerve or parotid carcinoma are misdiagnosed as benign parotid tumors prior to or during surgery. Remedial measures are usually required when the pathological diagnosis of a malignant parotid tumor is confirmed following surgery. The aim of the present study was to systematically evaluate reoperation subsequent to treatment with non-standardized procedures for malignant parotid tumors, and to explore the preoperative diagnoses, the primary procedure selection and the necessity of reoperation following non-standardized procedures in malignant parotid tumors. A total of 30 patients who met the inclusion criteria, were diagnosed with a malignant parotid tumor and underwent reoperation following the use of a non-standardized procedure were included in the present study. Surgical conditions and clinical data were analyzed. Among the patients with a malignant parotid tumor who underwent reoperation subsequent to a non-standardized procedure, the incidence of residual tumor, as confirmed by pathological examination, was 63.3% (19/30). The intact facial nerve preservation rate was 83.3% (25/30), the facial nerve branch resection rate was 6.7% (2/30), the facial partial nerve resection rate was 6.7% (2/30) and the facial nerve resection rate was 3.3% (1/30). In total, 3 patients underwent facial nerve reconstruction, 3 patients underwent a local flap repair of skin defects in the parotid region and 3 patients underwent pectoralis major muscle flap repair. The current findings indicate that the qualitative diagnosis of malignant parotid tumors prior to surgery is difficult, there is a high incidence of residual tumor following non-standardized procedures, and that reoperation in a timely manner is required in such cases.
