**Core Concept**
The patient's presentation of a fracture in the symphysis (midline of the face) and left angle region (zygomaticomaxillary complex) suggests a complex facial fracture involving multiple bones and possibly the orbit. The treatment of such fractures requires a multidisciplinary approach, including ophthalmology, otolaryngology, and plastic surgery.

**Why the Correct Answer is Right**
The management of complex facial fractures involves reduction and stabilization of the fracture fragments, often with the use of internal fixation devices such as plates and screws. This is typically performed by a team of surgeons, including plastic surgeons, otolaryngologists, and ophthalmologists. The goal is to restore the normal anatomy of the face and orbit, allowing for proper healing and minimizing the risk of complications such as orbital entrapment or facial asymmetry.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because it does not provide a comprehensive treatment plan for complex facial fractures. While antibiotics may be used to prevent infection, they do not address the underlying fracture.
**Option B:** This option is incorrect because it is too narrow in scope, focusing only on one aspect of the fracture (the zygomatic arch). Complex facial fractures require a more comprehensive approach.
**Option C:** This option is incorrect because it is not a standard treatment for facial fractures. While pain management is important, it does not address the underlying fracture.

**Clinical Pearl / High-Yield Fact**
In the management of complex facial fractures, the timing of treatment is critical. Early reduction and stabilization of the fracture fragments can help minimize the risk of complications and promote proper healing.

**Correct Answer: D.**
