Local Anesthesia in Oral and Maxillofacial Surgery Part 2

What is the Vazirani-Akinosi (VA) technique used for?

• Anesthetizing the IAN, lingual, and long buccal nerve simultaneously

• Anesthetizing the maxillary nerve

• Anesthetizing the mandibular nerve

• Anesthetizing the glossopharyngeal nerve

What are the indications for VA technique?

• Patients with restricted mouth opening

• Cases of failure of IAN blocks

• Difficult-to-locate landmarks for IAN block

• All of the above

Why is the percentage of positive aspiration higher with IAN block compared to VA?

• Due to the close proximity of the inferior alveolar artery

• Due to the close proximity of the maxillary artery

• Due to the close proximity of the lingual artery

• Due to the close proximity of the facial artery

What is the Akinosi-Vazirani technique also known as?

• Closed Mouth Technique

• Open Mouth Technique

• Gow-Gates Technique

• Inferior Alveolar Nerve Block

What is the technique used for mental nerve block?

• Depositing the solution around the mental nerve as it exits the mandible at the mental foramen

• Injecting the solution into the mandible through the mental foramen

• Injecting the solution into the maxilla through the mental foramen

• Depositing the solution around the maxillary nerve

What areas are anesthetized in mental nerve block?

• Buccal mucosa and gingiva in the mandible anterior to the premolar area

• Lower lip mucosa and skin on the same side

• Mandibular teeth anterior to the mental foramen

• All of the above

What is the technique used for posterior superior alveolar nerve block?

• Inserting the needle into the height of the mucobuccal fold opposite the upper second molar tooth

• Inserting the needle into the height of the mucobuccal fold opposite the lower second molar tooth

• Inserting the needle into the height of the mucobuccal fold opposite the upper first molar tooth

• Inserting the needle into the height of the mucobuccal fold opposite the lower first molar tooth

What areas are anesthetized in posterior superior alveolar nerve block?

• Buccal alveolar mucosa and gingiva in relation to the maxillary molar teeth

• All the three maxillary molar teeth

• Mesiobuccal root of the first molar

• All of the above

What is the technique used for infraorbital nerve block?

• Inserting the needle into the mucosa medial to the mandibular ramus on a line parallel to a line drawn from the intertragic notch to the corner of the mouth

• Inserting the needle into the mucosa lateral to the mandibular ramus on a line parallel to a line drawn from the intertragic notch to the corner of the mouth

• Inserting the needle into the mucosa medial to the maxillary tuberosity on a line parallel to a line drawn from the intertragic notch to the corner of the mouth

• Inserting the needle into the mucosa lateral to the maxillary tuberosity on a line parallel to a line drawn from the intertragic notch to the corner of the mouth

What areas are anesthetized in infraorbital nerve block?

• Lower eyelid, lateral side of the nose, and the upper lip on the same side

• Buccal gingiva and mucosa, as well as the upper anterior and premolar teeth on the same side

• Mesiobuccal root of the first molar

• All of the above
