Otoplan是一种手术计划软件,旨在帮助人工耳蜗植入手术。其输出之一是基于成像参数的电极阵列类型的推荐。在这项回顾性研究中,我们评估了植入Otoplan软件推荐的阵列的患者与阵列选择不同于Otoplan推荐的阵列的患者之间听觉结局的差异.将114例患者的术前CT图像导入软件,并生成阵列建议。将这些与在手术过程中实际植入的阵列进行比较,在数组类型和长度方面。如建议,47%的患者接受了相同的阵列,34%的人接受了较短的阵列,18%的人接受了更长的阵列。出于与结构和听力保护有关的原因,83%的人接受了更灵活的阵列。接受较硬阵列的人有耳蜗畸形或骨化。一个否定的,尽管在12个月时的CNC评分与推荐阵列和植入阵列之间的差异绝对值之间观察到无统计学意义的相关性。总之,临床医生可能会稍微偏向于较短的电极阵列,因为他们认为更有能力实现完全插入。术前规划期间使用3D成像可提高临床医生植入较长电极阵列的信心,在适当的情况下,以达到最佳的听力效果。
Otoplan is a surgical planning software designed to assist with cochlear implant surgery. One of its outputs is a recommendation of electrode array type based on imaging parameters. In this retrospective
study, we evaluated the differences in auditory outcomes between patients who were implanted with arrays corresponding to those recommended by the Otoplan software versus those in which the array selection differed from the Otoplan recommendation. Pre-operative CT images from 114 patients were imported into the software, and array recommendations were generated. These were compared to the arrays which had actually been implanted during surgery, both in terms of array type and length. As recommended, 47% of patients received the same array, 34% received a shorter array, and 18% received a longer array. For reasons relating to structure and hearing preservation, 83% received the more flexible arrays. Those who received stiffer arrays had cochlear malformations or ossification. A negative, although non-statistically significant correlation was observed between the CNC scores at 12 months and the absolute value of the difference between recommended array and implanted array. In conclusion, clinicians may be slightly biased toward shorter electrode arrays due to their perceived greater ability to achieve full insertion. Using 3D imaging during the pre-operative planning may improve clinicians\' confidence to implant longer electrode arrays, where appropriate, to achieve optimum hearing outcomes.
