Side Effects and Complications
- Bleeding and Hematoma: Incomplete hemostasis during surgery may lead to postoperative bleeding and hematoma formation. Minor hematomas can be absorbed spontaneously, whereas severe hematomas may require surgical removal.
- Infection: If the surgical incision becomes infected, it may cause local redness, swelling, pain, and fever. Severe infections can impair wound healing and even lead to surgical failure. Therefore, strict adherence to medical advice for anti-infective treatment and wound care is essential after surgery.
- Facial Nerve Damage: The area surrounding the zygomatic bone is rich in nerves. Accidental injury to these nerves during surgery may result in facial sensory abnormalities such as numbness, tingling, or unnatural facial expressions. Most nerve injuries are temporary and improve gradually with recovery, though a small number of cases may lead to permanent nerve damage.
- Bilateral Asymmetry: Inconsistent treatment of the zygomatic bones on both sides during surgery, or differing postoperative recovery patterns, may result in facial asymmetry. Mild asymmetry can often be corrected with revision surgery, while severe asymmetry can significantly compromise the surgical outcome and facial aesthetics.
- Poor Bone Healing: Following zygomatic osteotomy, proper bone healing is critical. Inadequate healing may cause zygomatic displacement or facial deformities, necessitating further surgical intervention.
