BACKGROUND: We aimed to assess the efficacy of augmented reality technology assisted by three-dimensional (3D) computed tomography (CT) reconstruction, in facilitating microvascular decompression (MVD) during craniotomy for hemifacial spasm. METHODS: A retrospective analysis was conducted on 80 patients who underwent MVD for hemifacial spasm at Hebei General Hospital between January 2, 2020, and March 24, 2021. Among them, 43 patients received traditional craniotomy (assigned to the traditional group), while 37 patients underwent modified craniotomy (assigned to the modified group). The distinctive feature in the modified group involved employing 3D-CT reconstruction assisted by augmented reality technology, specifically utilizing Sina software, for precise localization of scalp incision. The impact of the modified method on surgery was assessed based on operation time, incision length, postoperative complications, long-term efficacy, and patient-reported outcomes. RESULTS: No significant differences in age, sex, disease duration, and disease side were observed between the two groups (P > 0.05). The modified group exhibited a significantly shorter average craniotomy time (29.68 ± 4.89 min vs. 34.19 ± 4.55 min, P < 0.001) and time to close the skull (25.22 ± 3.12 min vs. 28.95 ± 2.54 min, P < 0.001) compared to the traditional group. Additionally, the incision length in the modified group (59.69 ± 10.71 mm) was evidently lower than that in the traditional group (70.84 ± 11.27 ...
