Neuropathy of the infraorbital area following rapid palatal expansion: A case report

This case illustrates that MARPE, while effective and generally safe, can occasionally induce neuropathic complications extending beyond palatal branches to involve the infraorbital pathway. Mechanical stress redistribution in skeletally mature patients likely contributes to this outcome. Careful monitoring for atypical sensory changes, early recognition, and timely pharmacological intervention are essential to optimize prognosis. Further research is warranted to clarify biomechanical mechanisms and risk factors for trigeminal nerve injury during orthodontic maxillary expansion.
