Significant Factors Affecting the Operation Time for Benign Parotid Tumor

Abstract

Tumors of the parotid gland are fairly frequent among head and neck tumors. Parotidectomy for benign tumors is necessary for diagnosis and therapy. Furthermore, acquiring the skill for this operation is a significant step in the training course of an otolaryngologist Thus, it is useful to analyze the operation time and determine the factors affecting it to evaluate the progress in the operation skill. To measure the operation time and determine the factors affecting it, 71 cases, including 43 cases of pleomorphic adenomas and 28 cases Warthin's tumor, were retrospectively reviewed to the determine if the operation time depended on the age, sex, operated side, presence of complications, BMI, bleeding volume, tumor size, tumor location, exposure of branches of the facial nerve, and experience of the surgeon. Multivariate analysis was used to determine the factors correlated with the operation time. The results revealed that the bleeding volume, tumor size, tumor location and experience of the surgeon were significantly correlated with the operation time, whereas age, sex, operated side, presentation of complications and BMI showed no correlation with the operation time. Furthermore, surgeons with the experience of operating 20-39 cases took almost the same time for the operation as the surgeon with the experience of operating more than 40 cases. Taken together, to shorten the operation time, the inexperienced surgeon should start with smaller tumors and surgery in the superficial lobe in the initial training period, and supervision by well-experienced supervised surgeons is required until 30-40 are undertaken.

Predictors of Adverse Events After Parotidectomy

“…Finally, the procedure of parotidectomy itself is much less sensitive to obesity, as the head and neck are less adversely affected by excess adiposity, compared to the abdomen and thorax. 50 The only risk factor for surgical complications was current smoking history (OR = 1.81; 95% CI, 1.08-3.05; P = .025). Our findings provide further validation of the risks associated with smoking, which are numerous and well established in the surgical literature.…”

Assessment of cervical lymph node metastasis for therapeutic decision-making in squamous cell carcinoma of buccal mucosa: a prospective clinical analysis

“…The patient factors include previous treatments and medical condition of the patient. Competence and convenience of the surgeon, economics and compliance of the patients, and expected complications also play their role in treatment planning [5]. Approximately 300 lymph nodes are located in the head and neck and they comprise 30% of the total 800 lymph nodes in the human body.…”
