GRAFTS SURVIVAL

It depends on several factors, such as recipient bed, vascularization and nutritional contribution. The following factors also affect:

 

1-Recipient bed quality, ischemia y reperfusion:

Recipient site of the graft must be under optimum conditions. There can´t be any active infectious processes and its vascularization must be adequate so that it can nourish grafts.

 

2-Physical trauma of follicles:

Follicular trauma, even done by stretching, folds or squashing is enough for reducing hair follicular growth. Deterioration phenomenon is shown by electronic microscope. A light touch on bulb could cause growing reduction from 35 to 64 %.

 

3- Solutions for preservation:

There are only a few ways for follicular preservation, such as:

Saline 0,9%

Ringer Lactato

A-Cell

Hypothermosol

 

4-Hydration:

Only 3 minutes are enough for follicles to start spoiling, so follicular growth decreases. There is mayor deterioration of 1-hair follicular units compared to 2, 3, and 4-hair ones.

 

5-Density:

High density of procedures which have more than 50 follicles/cm2 t has low survival compared to others having lower density. This phenomenon occurs due to ischemia-reperfusion effect.

 

6-Temperature:

Cold protects against physical damage. 40 º C temperature is ideal in order to maintain follicles viable and to help survival rate.

 

7-Time:

Dr. Bob Limmer in 1992 carried out a study consisting of 200 follicular units in different periods of time out of the body and these are the results he got:
