Ans. A

Explanation:

 

Dangerous area of face

Dangerous area of face includes upper lip and anteroinferior part of nose including the vestibule. This area freely communicates with the cavernous sinus through a set of valveless veins, anterior facial vein and superior ophthalmic vein. Any infection of this area can thus travel intracranially leading to meningitis and cavernous sinus thrombosis.

Vein draining dangerous area                                                                                                                  

  • Through facial veins communicating with ophthalmic veins (both having no valve)
  • Through the pterygoid plexus of veins which communicate with facial vein on one hand and the cavernous sinus through emissary vein on the other hand.

 

Deep connections of the facial vein include:

  • A communication between the supraorbital and superior ophthalmic veins.
  • Another with the pterygoid plexus through the deep facial vein which passes backwards over the buccinator. The facial vein communicates with the cavernous sinus through these connections. Infections from the face can spread in a retrograde direction and cause thrombosis of the cavernous sinus. This is specially likely to occur in the presence of infection in the upper lip and in the lower part of the nose. This area is, therefore, called the dangerous area of the face.

Q. 4

Complication of trauma to danger area of face ‑

 A

Cavernous sinus infection

 B

Meningitis

 C

Visual loss

 D

Loss of memory

Q. 4

Complication of trauma to danger area of face ‑

 A

Cavernous sinus infection

 B

Meningitis

 C

Visual loss

 D

Loss of memory

Ans. A

Explanation:

Ans. is ‘a’ i,e., Cavernous sinus infection

The area of upper lip and the lower part of nose is the danger area of face. It is due to that this area is the common site of infection.

This area is drained by facial vein which communicates with the cavernous sinus through the superior ophthalmic vein and pterygoid venous plexus through the emissary vein.

In case of any infection of this area it may spread to the cavernous sinus causing infection and/or thrombosis.


Q. 5

Most common nerve injured in face lift surgery is

 A

Zygomatic branch of the facial nerve

 B

Greater auricular nerve

 C

Mandibular branch of facial nerve

 D

Frontal branch of facial nerve

Q. 5

Most common nerve injured in face lift surgery is

 A

Zygomatic branch of the facial nerve

 B

Greater auricular nerve

 C

Mandibular branch of facial nerve

 D

Frontal branch of facial nerve

Ans. D

Explanation:

Ans. is ‘d’ i.e., Frontal branch of facial nerve

Nerve injury during facelift surgery

  • Some sensory reduction after facelift surgery is considered a consequence and not a complication of facelift surgery.
  • Care must be taken to avoid injury to the greater auricular nerve.
  • The most commonly injured nerve is the frontal branch of the facial nerve.
