Bipolar dissection technique in parotid gland surgery.

Parotid gland surgery (PGS) has to manage the balancing act between sufficient radicality and preservation of functional structures. While many studies evaluate post-therapeutic complication due to different extent of surgery, the current study introduces bipolar dissection (BP) being a fast and safe preparation technique.Analysis of clinical parameters (age, sex, tumour entity, treatment modalities, facial nerve palsy, bleeding, saliva fistula and Frey's syndrome) of 319 consecutively included patients who underwent extracapsular dissection and superficial/total/radical parotidectomy. Subgroup analysis was done according to the preparation technique (cold vs BP).Facial nerve palsy rate increased with the extent of PGS (p < .0001). There were no differences in the risk of post-operative bleeding, salivary fistula and Frey's syndrome. BP resulted in a significant reduction of operation time (p = .04), postoperative bleeding (p = .001) and salivary fistula (p = .045) when compared with cold preparation.Ubiquitous available BP allows fast and safe PGS regardless its extent.
