摘要

Dysphagia is a common complication following posterior fossa tumor (PFT) resection, primarily due to brainstem compression and involvement of lower cranial nerves. This study aims to evaluate pre- and postoperative swallowing function, identify clinical indicators of dysphagia, and assess outcomes following structured rehabilitation. A retrospective study was conducted on 38 adults who underwent PFT resection at a tertiary care center. Swallowing assessments were conducted preoperatively, started with prophylactic measures and continued regular follow up at 1, 3, 6, 9, and 12 months postoperatively. Statistical analysis included Pearson’s chi- square test, Fisher’s exact test with significance set at p < 0.05. Preoperatively, 10 (26.31%) of patients had dysphagia and received prophylactic swallowing exercises. Postoperatively, 28 (73.6%) developed dysphagia, with 22 (57.1%) requiring enteral feeding. Significant clinical predictors of postoperative dysphagia included abnormal maximum phonation duration (MPD) (p = 0.008), diminished gag reflex (p = 0.01) vocal cord palsy (p = 0.03) and suboptimal Dysphagia Handicap Index (DHI) score (0.02). Swallowing function improved in 21 (71%) by 1 month, 29(76%) by 3–6 months, 32 (84%) by 9 months, and 35 (92%) by 12 months. There is a high incidence of postoperative dysphagia following PFT resection. Early screening, identification of key predictors, risk factors and structured rehabilitation are crucial for optimal recovery and functional swallowing outcomes. An integrated neurosurgical dysphagia management protocol is recommended.
