Infraorbital Nerve block Intra oral method

Summary

This instructional video demonstrates how to perform infraorbital nerve anesthesia using the intraoral technique. The process begins with locating the needle insertion point between the upper right teeth, specifically between the upper 4th and 5th teeth. The needle is directed toward the infraorbital foramen, which is roughly 1 cm below the infraorbital margin. A small amount of anesthetic is slowly injected, and the area is massaged to ensure proper distribution of the anesthesia around the nerve. The video concludes by mentioning that the extraoral approach will be shown in a future tutorial.

Takeaways

• 😀 The infraorbital nerve anesthesia can be performed using two methods: interoral and extraoral.
• 😀 The video focuses on demonstrating the interoral method of anesthesia for the infraorbital nerve.
• 😀 The injection site is located between the upper right teeth, specifically between the upper 4th and 5th teeth.
• 😀 The needle should be inserted parallel to the line directed toward the infraorbital foramen, located about 1 cm below the infraorbital margin.
• 😀 A couple of drops of anesthetic are applied gently before the needle is advanced toward the infraorbital margin.
• 😀 Slow injection of the anesthetic (a couple of milliliters) helps ensure proper placement around the infraorbital nerve.
• 😀 When the liquid is injected, it can be felt under the thumb, indicating the correct positioning around the infraorbital nerve.
• 😀 The anesthetic follows a path in line with the mental nerve, infraorbital nerve, and supraorbital nerve when aligned with the pupil.
• 😀 After injection, massaging the area helps distribute the anesthetic around the infraorbital nerve.
• 😀 The next demonstration will cover the extraoral approach for infraorbital nerve anesthesia.

Q & A

What are the two ways to perform infraorbital nerve anesthesia?

The two ways to perform infraorbital nerve anesthesia are the intraoral approach and the extraoral approach.

What is the starting point for the intraoral approach to infraorbital nerve anesthesia?

For the intraoral approach, the starting point is between the upper right teeth, specifically between the upper four and five.

How should the needle be positioned during the intraoral approach?

The needle should be positioned parallel to the area, directed toward the infraorbital foramen, which is about 1 cm below the infraorbital margin.

What should be done once the needle is in position for the injection?

Once the needle is in position, a couple of drops should be injected, followed by introducing the needle gently toward the infraorbital margin and injecting a small amount of solution very slowly.

How can you tell if the injection is in the correct area around the infraorbital nerve?

You can tell the injection is in the correct area by feeling the liquid under your thumb, which indicates it is around the infraorbital nerve.

What anatomical line is used as a reference for positioning during the procedure?

A line drawn from the pupil can be used as a reference, as it aligns with the mental nerve, infraorbital nerve, and supraorbital nerve.

What is the next step after injecting the anesthesia in the correct area?

After the injection, you should gently massage the area where the liquid was injected, which should be around the infraorbital nerve.

What does the term 'infraorbital foramen' refer to?

The infraorbital foramen is a small hole located just below the infraorbital margin, where the infraorbital nerve passes through.

How can the two approaches (intraoral and extraoral) be distinguished in this procedure?

The intraoral approach involves injecting the anesthesia inside the mouth, while the extraoral approach involves injecting from the outside of the mouth, typically around the cheek area.

Why is the procedure done slowly and gently when injecting the anesthesia?

The procedure is done slowly and gently to ensure proper distribution of the anesthetic around the nerve, minimizing discomfort and avoiding damage to surrounding tissues.
