El Paso Forehead Lesion Removal Explained by Experts

El Paso Forehead Lesion Removal: Integrative Care Guide

Abstract

Welcome to our educational series. I’m Dr. Alex Jimenez, and today, I’m excited to share insights into a common yet crucial procedure: the regional nerve block. Specifically, we’ll explore its use for minor forehead procedures, such as removing a skin lesion. This post will take you on a step-by-step journey, explaining the anatomy of the key nerves involved—the supraorbital and supratrochlear nerves—and the precise technique for administering the block.

We’ll cover the physiological mechanisms of local anesthetics like lidocaine and explain why this method is often preferred for patient comfort and procedural success. I will also explain how this targeted care is a cornerstone of our multidisciplinary practice at Injury Medical Clinic. Here, we integrate advanced medical procedures under the direction of our esteemed Medical Director, Dr. Maria Guadalupe Cardenas, MD, with comprehensive chiropractic and functional medicine protocols. This collaborative model allows us to provide holistic, patient-centered care that addresses both immediate needs and long-term wellness.

Our Collaborative Care Model: Blending Medicine and Chiropractic

At Injury Medical Clinic, we have cultivated a unique environment where different medical disciplines work in synergy. Our practice is built on a multidisciplinary foundation, led by me and our Medical Director and Collaborative Physician, Dr. Maria Guadalupe Cardenas, MD. Dr. Cardenas is a highly respected, board-certified Internist with over four decades of experience (NPI #1164426749, Texas MD License #J2933). Her extensive medical knowledge provides the essential oversight and direction for all medical procedures performed at our clinic.

This collaborative setup is a hallmark of modern integrative healthcare. It allows us to offer a broad spectrum of services under one roof:

• Medical Oversight (Dr. Cardenas): Guiding all medical interventions, from minor procedures like the one detailed today to complex diagnostics and treatment plans.
• Chiropractic and Neuromusculoskeletal Care (Dr. Jimenez): Focusing on spinal health, nervous system function, and biomechanics. Chiropractic adjustments and therapies are crucial for restoring alignment and reducing nerve interference, which complements medical treatments by enhancing the body’s overall function and healing capacity.
• Functional Medicine: Investigating the root causes of dysfunction and creating personalized health plans that address diet, lifestyle, and biochemical imbalances.
• Rehabilitation and Personal Injury Care: Providing comprehensive therapies to help patients recover from injuries, improve mobility, and regain strength.

By integrating these fields, we ensure that a patient undergoing a simple medical procedure also benefits from a holistic assessment. For instance, a skin lesion could be related to systemic inflammation, which we can explore through a functional medicine lens. Chiropractic care can enhance post-procedural recovery by optimizing nervous system communication and reducing physical stress. This integrated model ensures that we don’t just treat a symptom; we care for the entire person.

Understanding the Forehead Nerve Block: Anatomy and Rationale

Today, I performed a nerve block on a patient who needed a lesion removed from her left forehead. Instead of numbing a large area with multiple injections around the lesion, which can be more painful and distort tissue, a regional nerve block is a more elegant and effective solution. This technique involves targeting the specific nerves that provide sensation to that area of the forehead.

The primary nerves we target are:

• The Supraorbital Nerve: This is a major sensory nerve of the forehead. It is a branch of the trigeminal nerve (cranial nerve V) and emerges from the skull through a small opening or notch in the upper margin of the eye socket, known as the supraorbital foramen or notch. Its path runs directly superior to the pupil when the patient is looking straight ahead. Blocking this nerve effectively numbs a large portion of the forehead and the front of the scalp.
• The Supratrochlear Nerve: This smaller nerve is also a branch of the trigeminal nerve. It exits the orbital rim more medially, closer to the bridge of the nose, just above the inner corner (canthus) of the eye. It provides sensation to the lower, central forehead.

By blocking both nerves, I achieve complete anesthesia of the entire ipsilateral (same side) forehead, creating a perfect, pain-free field for the procedure.

The Step-by-Step Procedure for a Forehead Nerve Block

Precision and a thorough understanding of anatomy are paramount when performing a nerve block. Here is a detailed breakdown of the steps I took to ensure the procedure was safe, effective, and as comfortable as possible for the patient.

1. Preparation and Landmark Identification

The first and most critical step is accurately identifying the anatomical landmarks.

• Locating the Supraorbital Foramen: I began by palpating the orbital rim, which is the bony ridge that forms the top of the eye socket. With the patient looking forward, I drew an imaginary vertical line up from the center of her pupil. The supraorbital foramen is located along this line on the orbital rim. I used my thumb to apply gentle pressure and locate this exit point.
• Locating the Supratrochlear Nerve Exit: Next, I moved my thumb medially along the orbital rim toward the bridge of the nose. The supratrochlear nerve emerges just above the inner canthus of the eye.
• Aseptic Technique: Before any injection, I thoroughly cleansed the skin with an alcohol prep pad to minimize the risk of infection. This is a non-negotiable step in any invasive procedure.

2. Administering the Supraorbital Nerve Block

With my landmarks identified, I proceeded with the first injection.

• Patient Communication: I always inform the patient right before the needle insertion to help them prepare. I said, “One, two, three,” and then gently inserted the needle. Acknowledging the initial sting (“I know that hurts”) is important for maintaining trust and rapport.
• Injection Technique: I pinched the skin to lift it slightly, which helps to distract from the needle prick and ensures the anesthetic is delivered to the subcutaneous space. I inserted the needle at a perpendicular angle until I felt it gently touch the bone of the orbital rim. This tactile feedback confirms that I am at the correct depth and location, directly over the foramen.
• Safety First: I kept my thumb firmly on the orbital rim below the injection site. This serves two purposes: it confirms my position and acts as a physical barrier to prevent the needle from accidentally slipping below the rim and into the orbit, which could cause serious injury.
• Delivering the Anesthetic: I then aspirated gently (pulled back on the plunger) to ensure I was not in a blood vessel. After confirming a negative aspiration, I slowly injected approximately 0.5 mL of lidocaine. As I injected, I felt the fluid create a small bulge, or wheal, under the skin, confirming it was delivered to the correct tissue plane.

3. Administering the Supratrochlear Nerve Block

The second injection followed a similar protocol, targeting the supratrochlear nerve.

• Landmark Confirmation: I moved to the medial aspect of the orbital rim, just above the inner corner of the eye.
• Injection Technique: Again, I communicated with the patient and inserted the needle until it contacted the bone. I kept my thumb on the orbital rim for safety.
• Anesthetic Delivery: I aspirated and then slowly injected another 0.5 mL of lidocaine. Again, I felt the anesthetic solution bulge against my thumb, confirming proper placement.

After both injections, I applied gentle pressure to the sites. This helps to disperse the anesthetic fluid throughout the tissues and encourages it to permeate around the nerve sheaths. It also helps minimize bruising (ecchymosis).

How Lidocaine Works: The Physiology of Anesthesia

The medication I used, lidocaine, is a local anesthetic belonging to the amide class. Its mechanism of action is fascinating and occurs at a cellular level.

1. Blocking Sodium Channels: Nerves transmit signals—including pain signals—by generating electrical impulses called action potentials. These impulses form when sodium ions (Na⁺) rapidly enter the nerve cell through specialized gateways called voltage-gated sodium channels.
2. Interrupting the Signal: Lidocaine diffuses into the nerve cell and binds to these sodium channels from the inside. This binding action physically blocks the channel, preventing sodium ions from flowing into the cell.
3. Preventing Depolarization: Without sodium influx, the nerve membrane cannot depolarize and generate an action potential. As a result, signal transmission is halted. Pain signals from the forehead cannot reach the brain, and the patient feels no pain in the anesthetized area.

This process begins within minutes and provides effective anesthesia for the duration of the minor procedure.

The Finishing Touches and the Role of Integrative Care

Following the nerve block, I administered a very small amount of supplemental lidocaine directly around the lesion itself. While the block numbs the entire region, this extra step ensures the immediate area is completely desensitized and also provides a vasoconstrictive effect (if lidocaine with epinephrine is used), which can help control bleeding during the removal.

This procedure, while medical in nature, shows how we apply our integrative philosophy.

• Pre-Procedure: Our functional medicine approach might have already identified inflammatory triggers or nutritional deficiencies that could affect skin health and healing. Addressing these beforehand can lead to better long-term outcomes.
• During the Procedure: My training as both a nurse practitioner and a chiropractor gives me a deep appreciation for the body’s intricate neurological and musculoskeletal systems. This allows for precise, anatomy-driven procedures that minimize patient discomfort and maximize effectiveness.
• Post-Procedure: Chiropractic care can enhance recovery. A well-aligned spine and properly functioning nervous system create an optimal internal environment for healing. By reducing systemic stress through chiropractic adjustments, we help the body direct its resources toward repairing the tissue at the procedure site.

Our goal is always to provide care that is not only effective in the short term but also supports the patient’s overall health journey. This commitment to modern, evidence-based, integrative care defines our practice.
