Displacement and Functional Impairment:• Significant displacement can result in facial asymmetry, malocclusion, trismus (limited jaw movement), and diplopia (double vision).2. Aesthetic Considerations:• Proper alignment of the zygomatic arch is necessary to maintain facial symmetry. Restoring the malar eminence is crucial for cosmetic outcomes. Inadequate reduction may result in visible deformity.3. Fracture Stability:• ZMC fractures typically involve the zygomatic arch, lateral orbital rim, inferior orbital rim, and zygomaticomaxillary buttress. Evaluating these structures’ stability is key to determining the need for rigid fixation.4. Orbital Volume and Eye Position:• Displacement may affect orbital volume, leading to enophthalmos (posterior displacement of the eye) or exophthalmos (protrusion). Orbital floor fractures may need correction to prevent vision or cosmetic issues.5. Three-Dimensional Consideration:• ZMC fractures require evaluation in three planes: lateral, anterior-posterior, and vertical, to ensure proper anatomic reduction.6. Airway Considerations:• Severe fractures can compromise the nasopharyngeal airway, particularly if associated with Le Fort or other midface fractures.Indications for Surgical Repair:1. Significant Displacement (>2 mm):• Surgical repair is indicated if fracture fragments are displaced more than 2 mm to restore alignment and prevent deformity.2. Functional Impairment:• Surgery is needed for functional impairments like trismus or restricted eye movements, especially if diplopia persists.3. Cosmetic Deformity:• Surgery is indicated for asymmetry, flattening of the malar eminence, or enophthalmos to restore facial symmetry.4. Orbital Involvement:• Surgery is required for fractures affecting the orbital floor or rim that result in enophthalmos or entrapment of orbital soft tissue.5. Nerve Injury:• Persistent sensory disturbances, such as infraorbital nerve dysfunction, may require surgical decompression.6. Open Fractures:• Open fractures need urgent surgical debridement and stabilization to prevent infection and ensure healing.7. Complex Fractures:• Multiple midfacial fractures, such as Le Fort II or III fractures, often require surgical repair to restore facial contour and stability.References:1. Strong, E. B., & Gary, C. G.
