The alterations in sensitivity of the infraorbital nerve following fractures of the zygomaticomaxillary complex.

52 patients with fractures of the zygomaticomaxillary complex associated with hypoaesthesia of the infraorbital nerve were evaluated as to the degree of residual impairment in sensitivity. Those with minor displacements or no displacements at all showed complete recovery. Early treatment was associated with better results, while no correlation was found between the degree of anatomical reduction and the improvement in nerve sensitivity. The results appeared to be better when the lateral orbital approach was part of the treatment.
