A zygoma fracture might result in a condition called infraorbital nerve numbness.
The infraorbital nerve block is frequently used to provide facial regional anesthesia. Compared to local tissue infiltration, the treatment has various advantages.
A nerve block frequently induces anesthesia with less medicine than is necessary for local infiltration. The ipsilateral lower eyelid, upper cheek, side of the nose, and upper lip are all anaesthetized via an infraorbital nerve block.
The most frequent consequence of zygomatic fractures is malunion, which is brought on by insufficient reduction and fixation and manifests as malocclusion, facial asymmetry, and exophthalmos.
Although extraocular muscle entrapment is primarily caused by the original fractures, it can also develop as a result of fracture healing.
Therefore, the correct answer is option b. infraorbital nerve anesthesia
