Postoperative spinal deformity is the most common complication after surgical resection of intradural tumors, and posterior longitudinal ligament complex (PLC) plays an important role in postoperative spinal deformity. In this study, we investigated the role of PLC in spinal deformity after the surgical treatment of intradural tumors.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>We analyzed the data of 218 consecutive patients who underwent intradural tumor resection from 2000 to 2018 in this retrospective study. Before 2010, patients underwent laminoplasty without maintaining the integrity of PLC (laminoplasty group, <jats:italic>n<\/jats:italic>\u00a0=\u00a0155). After 2010, patients performed single\u2010port laminoplasty to maintain the integrity of PLC (laminoplasty retain posterior ligament complex group, <jats:italic>n<\/jats:italic>\u00a0=\u00a063). The score of quality of life, painful cortex, spinal cord movement, progressive kyphosis or scoliosis, perioperative morbidity, and neurological results were analyzed in the laminoplasty group and laminoplasty retain posterior ligament complex group. The distributed variable was shown as mean\u2009\u00b1\u2009standard deviation and an independent <jats:italic>t<\/jats:italic>\u2010test or one\u2010way analysis of variance was calculated.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>There are 155 patients (71.1%) included in the laminoplasty group, and 63 patients (28.9%) in the laminoplasty retain posterior ligament complex group. The average age of patients was 42\u2009\u00b1\u20092.3\u2009years, and the average modified McCormick score was 2. There were 158 (72.4%) patients with intramedullary tumors and 115 (52.7%) patients with extramedullary tumors. The length of hospital stays (8\u2009days vs. 6\u2009days; <jats:italic>p<\/jats:italic>\u00a0=\u00a00.023) and discharge to inpatient rehabilitation (48.4% vs. 26.9%; <jats:italic>p<\/jats:italic>\u00a0=\u00a00.012) were significantly lower in the laminoplasty retain posterior ligament complex group than the laminoplasty group. There was no significant difference in the risk of progressive deformity between the two groups at 18\u00a0months after surgery (relative risk 0.12; 95% confidence interval [CI] 0.43\u20131.25; <jats:italic>p<\/jats:italic>\u00a0=\u00a00.258) and at 20\u00a0months after surgery (relative risk 0.24; 95% CI
