Laxometer – Instruction to Use

The Laxometer was invented by Dr. Parsa Mohebi in 2007 and was improved to become more precise in 2011 making it in its current shape known as “Laxometer II”. The purpose of the Laxometer is to measure scalp mobility in a more objective way. Here are step by step instructions of how to use the Laxometer device on a patient who is undergoing a strip procedure.

1. The Laxometer should be held in an upright position with its mobile part placed firmly against the scalp.
2. The tracing rubber ring should be moved to its most superior position so it is touching the ring of the mobile part.
3. While keeping a good grip of the scalp, the mobile part of the Laxometer should pull the scalp to its most superior position until we cannot move the scalp more.
4. Then the operator should hold and stabilize the measuring rod with the other hand and keep it in a fixed position.
5. The final step is to pull the scalp to its most inferior position by moving the mobile part down. This motion is done while the measuring rod is held in a fixed position with the operator’s other hand. This move pulls the tracing rubber ring to its most inferior position on the measuring rod. The position of the tracing rubber ring on measuring rod shows the maximum mobility of scalp from its most superior to most inferior position.

The objective measurement of the scalp from the most superior to most inferior position is extremely important before undergoing a strip hair transplant procedure. The Laxometer Device enhances the safety of the hair transplant procedure by allowing the surgeon to record how much distance is needed in the donor area in order to close the wound.
