Steps in performing hair transplantation with Choi Implanter Pen

The process of hair transplantation utilising the Choi Implanter Pen entails a series of precise procedures aimed at achieving optimal graft placement and subsequent success. Choi Implanter Pen is a specialised instrument designed to enhance the accuracy and precision of hair follicle implantation in the context of a hair transplant surgery. The following is a comprehensive outline of the procedural stages involved:

Preoperative Assessment

Initiate the process with a comprehensive preoperative evaluation, encompassing an analysis of the patient’s hair loss pattern, assessing the availability of donor areas, and engaging in a dialogue about the patient’s desired outcomes.

Donor Hair Harvesting

Proceeding to the next step involves the identification and preparation of the donor area, typically situated at the rear of the head. Utilizing the Follicular Unit Extraction (FUE) method, individual hair follicles are meticulously harvested one by one.

Follicle Extraction

Following the harvesting phase, the extracted hair follicles undergo careful scrutiny and categorization under a microscope to verify their quality and viability. This meticulous examination is imperative for the selection of the healthiest follicles intended for transplantation.

Recipient Site Preparation

Prepare the recipient area, where the hair is slated for transplantation, by creating small incisions or holes. The density, angle, and direction of these incisions play a pivotal role in achieving a result that appears natural.

Choi Implanter Pen Loading

Utilize the Choi Implanter Pen for the implantation of hair follicles into the pre-made incisions. The pen, equipped with a hollow needle, allows for the loading and direct implantation of the graft into the scalp. This approach minimizes trauma to the grafts and guarantees accuracy in terms of depth and angle.

Implantation with Choi Implanter Pen

Exercise control over the depth, angle, and direction of graft placement with the Choi Implanter Pen, thereby enhancing the precision of the procedure. This control is paramount for achieving a natural-looking hairline and ensuring optimal coverage.

Graft Placement Control

Provide the patient with postoperative care instructions, including guidance on hair washing, recommendations to avoid strenuous activities, and adherence to prescribed medications to facilitate the healing process.

Postoperative Care

Provide the patient with postoperative care instructions, including guidelines on washing the hair, avoiding strenuous activities, and taking any prescribed medications to aid in the healing process.

Follow-Up Appointments

Establish follow-up appointments to monitor the progress of the transplanted hair and address any queries or concerns the patient may have.

Proficiency and experience are essential when performing hair transplantation with the Choi Implanter Pen. Adherence to ethical and professional standards throughout the procedure, coupled with comprehensive postoperative care, ensures the best possible outcomes.
