Oral Surgery

For extraoral maxillary nerve block the target is�
�1. Anterior to lateral pterygoid plate
�2. Posterior to lateral pterygoid plate
�3. Pterygomandibular fossa
�4. Pterygomandibular fissure

Option 1

Option 2

Option 3

Option 4

📝 Explanation:

Anterior to lateral pterygoid plate. In the extraoral maxillary nerve block, the needle is inserted at the posterior aspect of the condylar neck and directed anteriorly to target the pterygomandibular space, which contains the maxillary nerve and its branches. This technique is used to anesthetize the molars and premolars of the upper jaw and is also known as the Vazirani-Akinosi technique.

Oral Surgery

Diagnosis of dry socket is done by
1) History
2) Clinical examination
3) Radiographs
4) None of the above

Option 1

Option 2

Option 3

Option 4

📝 Explanation:

Dry socket (alveolar osteitis) is a clinical diagnosis.

History: Patients typically report severe, throbbing pain starting 2�4 days after extraction, often radiating to the ear or temple.

Clinical examination: Empty socket with exposed bone, absence of clot, foul odor, and tenderness.

Radiographs: Usually not diagnostic for dry socket. They are only used to rule out retained root fragments or other pathology.

History supports the diagnosis, but the definitive diagnosis is made clinically by examining the socket.

Oral Surgery

A surgical procedure required bilateral block. A bilateral inferior alveolar nerve block is�
�1. Not contraindicated
�2. Should rarely be preformed
�3. May cause space infection
�4. None of the above

Option 1

Option 2

Option 3

Option 4

📝 Explanation:

A bilateral inferior alveolar nerve block is not inherently contraindicated. It is commonly performed in cases requiring surgery on both sides of the mandible. However, it should be done with caution in patients with certain medical conditions or anatomical variations that could increase the risk of complications. It is important to assess each patient individually before administering the block.
