“…The abducens nerve originates from the cerebral cortex, descends to the brainstem nuclei, and then emits secondary neuronal bers to innervate the lateral rectus muscle of the eye [14][15] . Lesions affecting the horizontal gaze center in the pons, as well as lesions in the cerebral cortex and cortical gaze center, can result in paralysis of the extraocular muscles [16] .…”

Objective: This study aimed to assess the therapeutic efficacy of surgical and conservative treatments in patients with traumatic abducens nerve injury on neurofunctional recovery based on dual-center clinical experience. Methods: A retrospective analysis was conducted on the clinical data of 71 patients with traumatic abducens nerve injury. Patients were categorized into the operation group and the conservative treatment group based on whether patients underwent surgical intervention during their hospitalization. A comparison was made between the two groups regarding ocular motility recovery before and after treatment. In addition, patients were further divided into complete paralysis and incomplete paralysis groups based on their initial ocular position score for subgroup analysis. Results: The overall effective rate of conservative treatment group was 81.82%, while the overall effective rate of operation group was 88.89%. there is no statistically significant difference (χ2=0.173, P=0.678) between two groups. Subgroup analysis indicated that both in the conservative treatment group and in the surgical group, the efficacy rate is significantly lower in the complete paralysis subgroup compared to the incomplete paralysis subgroup. Results showed the total effective rate was 92.31% vs .66.67%（χ2=4.70, P<0.05） on conservative treatment group and 100% vs .66.67% （χ2=3.857, P<0.05）on operation group. Conclusion: The total effectiveness rate of the conservative treatment group was similar to that of the operation group, suggesting no difference in treatment effectiveness between two treatment plans, and the prognosis of traumatic abducens nerve injuries remains favorable. However, the higher the initial ocular position score of the patient, the more severe the paralysis symptoms, and the worse the treatment effect. Thus, treatment choices should be individualized to ensure optimal results.

“…Within the cavernous sinus, it runs alongside the internal carotid artery and enters the orbit through the middle part of the superior orbital fissure and innervates the lateral rectus muscle. [ 7 ] In the absence of hematoma or fracture, the mechanism of injury to the abducens nerve is believed to be stretching against the apex of the temporal bone just before it enters the Dorello's canal. [ 8 ]…”
