Question 1

The needle is moved toward the condyle's neck in?

Accepted Answer

Gow-gates technique

Answer

The Gow-Gates technique is a comprehensive mandibular nerve block where the anesthetic solution is deposited near the neck of the condyle. This approach aims to anesthetize the entire V3 division of the trigeminal nerve, providing widespread anesthesia to the mandibular teeth, buccal soft tissues, and tongue. Its target site is superior and posterior to the traditional inferior alveolar nerve block.

Question 2

What is the color code for a medium-level emergency patient?

Accepted Answer

Yellow

Answer

In emergency triage systems, color codes are used to quickly classify patients based on the severity of their condition and the urgency of treatment. Yellow typically designates patients with a medium-level emergency, indicating their condition is serious but not immediately life-threatening, allowing for a short wait for treatment. Red is for immediate life-threatening conditions, and black for deceased or expectant deceased.

Question 3

Mandibular nerve block using a closed mouth technique?

Accepted Answer

Akinosi method

Answer

The Akinosi method, also known as the Vazirani-Akinosi closed-mouth mandibular nerve block, is performed with the patient's mouth closed or only partially open. This technique is particularly advantageous for patients who have difficulty opening their mouths due to conditions like trismus. It targets the inferior alveolar, lingual, and buccal nerves from a medial approach.

Question 4

Which of the following ASA classifications applies to a patient who's under threat to life?

Accepted Answer

4

Answer

The American Society of Anesthesiologists (ASA) Physical Status Classification System assesses a patient's overall health before surgery. An ASA Class 4 patient is defined as having a severe systemic disease that is a constant threat to life. This classification indicates a high risk for anesthesia and surgical procedures.

Question 5

Muscle that has been penetrated in IANB?

Accepted Answer

Buccinator

Answer

During an Inferior Alveolar Nerve Block (IANB), the needle typically penetrates the buccinator muscle as it advances towards the pterygomandibular space. The buccinator muscle forms the bulk of the cheek and is superficial to the target nerves and vessels in this region. While other muscles are nearby, the buccinator is the one directly pierced by the needle.
