About

follicular unit extraction as a method of hair transplantation in cicatricial alopecia

Full description

The study will include 20 patients with cicatrical alopecia.Patients will be randomly assigned into two groups:Group (A):include ten patients will undergo (FUE) alone. Group (B): include ten patients will undergo(FUE) and (PRP).3-Surgical technique: Preoperative Investigations including complete blood count, coagulation profile and hepatitis viral markers. 1-Group(A): will undergo (FUE) Washing the scalp with antiseptic shampoo before the procedure. Tumuscentanaesthesia:The donor area is anesthetized with a lidocaine 1% solution diluted with 20 cc saline in addition to adrenaline. Creation of micropunches(0.7-1 mm) using micromotor. After removal of the punch,the follicular unit is extracted with Jweler's forceps. Extracted grafts are then placed on chilled saline gauze for maximum four hours until ready for transplantation. The recipient area is prepared with rectangular scalpel blades 1mm or hypodermic blades 0.9 mm. Implantation using fine tipped jweler's forceps. Finally, receptor and donor areas will be softly cleansed with saline and crepe bandage is applied. 2-Group (B): FUE+PRP The same procedure will be done but grafts will be placed in Prp solution. Prp session one week before transplantation then monthly for 3 monthes after (FUE). Preparation of PRP 10 cc blood will be aspirated in test tube contained a modified solution of anticoagulant,called acid-citrate-dextrose type (ACDA), in which the physiological pH will reached to preserve the platelet integrity. The first spin of whole blood sample will be at 2500 rpm for 4 minutes The second spin at 4000 for 20 minutes for obtained plasma. Platelets are separated as a pellet at the bottom of the tube from platelet-poor plasma (PPP) above. The platelet-rich pellet is resuspended in remaining amount of plasma. The resulting suspension is used as PRP. Prp is injected in the recipient area. 4-Follow up: Follow up clinically by digital photographs and trichoscopy 1 week after operation, after 3 months and after 6 months.
