DERMATOLOGIST in ATHENS

Dermatologist in Athens Dr Apostolos Karalexis was first trained at the University of Thessaloniki and completed his studies in Athens in Military Medicine. He then trained at the “Andreas Syngros” Hospital in the Dermatology – Venereology Department. After serving for two years at the Athens Naval Hospital he started his post-graduate training in Dermatologic Surgery initially in Greece at ¨Syggros¨ Hospital. In addition he trained in the USA at Tulane University, New Orleans, Louisiana especially in Dermatology and Dermatologic surgery.

DERMATOLOGIC SURGEON in ATHENS DR. KARALEXIS

As a dermatologic sergeon in Athens he currently holds the position of Director of the Dermatology Clinic at the Naval Hospital. Furthermore he is actively taking part in conferences in Greece and abroad as a speaker and lecturer.

Why should you trust Dermatologist Dr. Karalexis?

He has more than 20 years of experience in the field of Dermatology. All kinds of dermatological diseases such as psoriasis, lichen, eczema, warts, cutaneous lupus, acne, fungal infections, etc. are treated and cured, as well as venereal diseases such as warts, urethritis etc. while due to the specialization in hair diseases, cases such as hair loss, alopecia, etc.

Finally, he has great experience in the diagnosis and removal of tumors and skin moles.

Within a very large, modern and contemporary clinic and equipped with the latest equipment and Lasers, all kinds of therapies are undertaken at reasonable prices. Mostly we provide always the best human approach and respect to the patient’s psychology.

What is the modern dermatology?

Modern dermatology uses laser techniques and methods almost revolutionary. Let’s have a look at the evolution of dermatology. Over the past few decades, the deeper knowledge of the pathogenesis of many dermatological diseases has led to the development of new therapies such as biological agents in psoriasis, resulting in a “revolution” in their therapeutic approach and management. The evolution of technology has led to the discovery of Lasers to achieve a more youthful and desirable appearance. The contemporary dermatologist is a multidimensional scientist who should combine classical knowledge with modern technology.

Benefits of micrografts

Nearly undetectable: The main benefit of follicular unit micrografting is that the final results are nearly undetectable as transplants. The relocated hair follicles grow new hairs just as they had done in their previous location, and with expert placement of the grafts, the new hairs grow out in a natural way.

The individual small grafts can be placed in a way that mimics natural hair growth more easily than would be possible using old style full-size grafts alone. Many people who would in the past not be considered good candidates for full size grafts because the area requiring coverage is too large to be adequately covered with the limited amount of donor follicles available, are good candidates for follicular unit micrografting. With expert placement of the grafts, micrografting allows the look of more coverage, with less donor hairs.

Add density: Micrografts can be individually placed between other growing hairs, adding density to thin areas, before these areas become completely bald. Men just beginning to experience receding hairlines, and women just starting to have overall thinning, can both benefit from follicular unit micrografting procedures before their hair loss becomes more apparent.

Pain: Prior to surgery, all patients are given a “cocktail” consisting of a tranquilizer, a short-acting sleeping pill, and the pain kill. Most patients fall asleep within 15 minutes and wake up near the end of the procedure. During surgery the scalp is numbed with local anesthetics.

Variations by graft size and preparation: Dr. Karalexis recommended procedure is Follicular Unit micrografting. This procedure is used on everyone, men, women, new patients, and old patients seeking enhancements or repairs of grafts placed by other doctors.

The following procedures are not recommended

“Bare follicle” grafts: Some surgeons specially prepare single-hair “monografts” by separating follicular units and then trimming away from the individual follicles all excess fat and scalp tissue in an effort to promote fast revascularization. This additional handling may actually reduce the survival rate of the grafts, and Dr. Karalexis considers this to be a risky and unacceptable technique.

Machine cut grafts: Some procedures use machines to separate donor material into individual grafts, achieving great savings in time and labor. Sometimes these savings are passed on to patients in the form of cheaper hair transplant quotes. But these graft cutting machines are guillotine like devices with multiple blades, and do not identify individual follicles within each graft, so while every graft is uniform in size and there is less handling of each graft, there is also substantially more transection, or “cutting-in-half” of the follicles themselves. Although many transected follicles will still survive and grow normal hairs, skilled surgeons prefer the higher yield and whole follicles that result from individually hand cut grafts. Dr. Karalexis believes that there is no substitute for the graft-cutting judgment and surgical skill of a physician or experienced team of medical assistants.

Variations by recipient site preparation and graft placement

Slits: The standard procedure for placing Follicular Unit micrografts is small slits in the scalp, made with slender flat-bladed surgical instruments. Dr. Karalexis uses an especially fine blade called an MIS67, which was designed for use in eye surgery. Slits allow grafts to be placed between growing hairs and transplanted hairs, with less risk of damage to the adjacent hairs, thereby increasing hair density. Slits also hold the grafts securely during the healing process, and the slits heal very rapidly. With some patients however, the slits may compress the tissue around the new hairs and cause them to grow together as a tuft, with all of the hairs from a graft appearing to come out of a single hole. For this reason, slit grafting is usually done only with follicular unit micrografts having three hairs or less, so that the risk of graft compression is minimal.

Holes: Holes for larger minigrafts of 5-6 hairs used to be made with a circular punch called a trephine, however this size graft is rarely used at present. The trephine removes a tiny plug of scalp tissue to make a hole. The plugs are smaller than a grain of rice, but when they are all added up, they reduce the amount of bald scalp and thereby increase hair density. Holes have somewhat less of a tendency to compress grafts, but slightly increase the risk of grafts becoming loose before they have completely healed.

Laser transplants: “Laser transplants” use a cosmetic surgery laser to vaporize scalp tissue to make narrow recipient slots for placing micrografts and sometimes larger minigrafts. The laser slots are slightly wider than slits made with a metal blade, and may reduce graft compression with some patients. Laser slots have the potential to combine the advantages of both slits and holes, by allowing speedy graft placement between existing hairs, while also reducing bald scalp area and graft compression. Lasers however, also have some additional disadvantages.
The main disadvantage of lasers is that they cause some degree of thermal damage to the tissue in the recipient site for the graft, slowing the rate of healing, delaying the appearance of new hairs, and causing considerably more crusting at the graft site. The crusting associated with laser slots can sometimes still be visible 2 to 4 weeks after surgery, in comparison to the 2 to 4 days that is typical for with slits made with a metal blade.

Variations in graft placement pattern

A wide range of graft placement patterns exist, and most are custom tailored to each individual for each session. In general, micrografts are placed so that even with future hair loss, they will look natural. Some surgeons use a grid, or a grid pattern, to assure that individual grafts do not crowd other hairs and threaten their survival. Others place the grafts in a more random pattern, while taking care to allow adequate space between grafts. Dr karalexis selects the best graft placement method for each patient, for each procedure. Among the factors taken into consideration are the size of the grafts to be placed, the amount of existing hair on the scalp, the color contrast between the skin and hair, and the number of procedures to be performed as part of each patient’s complete treatment program.

Special Location Transplants: These are micrograft transplants to locations other than the scalp, such as the eyebrows, sideburns, mustache, and even eyelash areas. Often patients need special location micrografts to correct flaws from vehicle accidents, burns, or other surgical procedures. Others may need to cover scars from cosmetic surgery procedures, and some simply want to enhance their facial hair. Special location transplants require great care in the placement of each graft so that the angle and direction of the transplanted hairs mimic the natural pattern of hairs growing in those areas.
