# Golden period for treatment of open wound is? 

A. 2 hrs 

B. 4 hrs

C. 6 hrs 

D. 8 hrs 

The correct answer is B. 4 hours.

In the first 4 hours after a breach in an epithelial surface and underlying connective tissues, there is delay in the mobilisation of host defences.

Rhytidectomy is a surgical procedure meant to counteract the effects of time on the aging face. In the rhytidectomy procedure (also known as a “face-lift”), the tissues under the skin are tightened and excess facial and neck skin are excised. Rhytidectomy literally means wrinkle (rhytid-) removal (-ectomy).

The great auricular nerve, which supplies sensation to the skin of the ear and nearby skin is the most commonly injured in a rhytidectomy.
