GENERAL HISTOLOGY

Detailed explanation-1: -Frey syndrome. The best described and more frequent complication following parotidectomy is gustatory sweating or Frey syndrome.

Detailed explanation-2: -Facial nerve injury is a common risk associated with parotidectomy. If the facial nerve is injured during parotidectomy surgery, a patient can experience partial or total facial paralysis. With partial facial paralysis following a parotidectomy, some of a patient’s facial nerve branches are damaged.

Detailed explanation-3: -Transient paralysis of facial nerve is seen to vary from 15 % to 66 % in post-parotid surgery. The objective of this study was to find out the complications in post-parotidectomy with regards to facial nerve dysfunction since it is a vital structure encountered in parotid surgeries.

Detailed explanation-4: -Results: Incidence of postoperative facial nerve dysfunction was 42.7% on the first postoperative day, 30.7% at 1 month after the parotidectomy, and 0% at 6 months after the parotidectomy. The most common dysfunction was paresis in a single nerve branch (48.2%), in particular, the marginal mandibular branch.

Detailed explanation-5: -The most significant complication is the facial nerve dysfunction that can appear as paralysis (complete loss of function) or paresis (partial loss) (2, 3). In most cases, this facial paresis is temporary and recovery of nerve function is achieved before 6 months after surgery, usually within the first two months (4, 5).
