Predictors of facial palsy after surgery for benign parotid disease: Multivariate analysis of 626 operations

Abstract

Comorbid diabetes, and more extensive as opposed to partial superficial parotidectomy, may be associated with transient facial palsy following operation for benign parotid disease. The incidence of permanent facial palsy may be higher when a more extensive parotidectomy is performed.

Facial nerve paralysis postparotidectomy: A retrospective review of the prevalence and risk factors at a tertiary center

“…[8,9,11,12] In addition, long operative duration was also significantly associated with facial nerve paralysis as previously reported. [7,10] In previous studies, malignant lesions were more likely to be associated with permanent facial nerve paralysis.…”

“…[8] It is noteworthy that physician' years of experience and the use of surgical loupes also had no effect on postoperative facial nerve status. The present study had limitations indicating that the results must be interpreted with caution.…”

“…[7] Several factors have been associated with facial nerve injury including a history of malignant pathology, deep lobe involvement, lack of nerve monitoring, use of diathermy, surgical techniques, revision surgery, additional neck dissection, and diabetes. [8][9][10][11][12][13][14] In the present study, we aimed to determine the prevalence of postparotidectomy facial nerve paralysis and to identify risk factors associated with its development.…”

Stratifying the risk of facial nerve palsy after benign parotid surgery

“…4,5 Despite advances in operative technique, a significant proportion of patients undergoing parotid surgery still develop a post-operative facial palsy, with published prevalences of up to 57 per cent for temporary palsy and up to 7 per cent for permanent facial palsy. [6][7][8][9][10] This study aimed to evaluate risk factors for developing facial palsy in patients undergoing parotidectomy for treatment of benign parotid disease.…”

Facial mimicry after conservative parotidectomy: a three-dimensional optoelectronic study

“…Facial nerve paralysis is a possible complication following parotidectomy. When surgery is performed for benign diseases such as pleomorphic adenoma, temporary nerve palsy has been reported in 18-44% of patients, depending on the type of surgical removal (total conservative parotidectomy vs. superficial parotidectomy) patients regain normal function within 1 year of surgery, but permanent facial palsy occurs in 1-4% 1,4,[12][13][14][15] .…”
