ABSTRACT
【Objective】 To evaluate the efficacy and weight of sellar floor repair techniques such as different dura suture, bone reconstruction, and pedicled nasoseptal flap (PNSF) on the skull base reconstruction of medium and high flow cerebrospinal fluid leakage during endonasal endoscopic pituitary adenoma surgery. 【Methods】 We collected the data of Grade 2-3 cerebrospinal fluid leakage (Kelly grade) during endonasal endoscopic pituitary adenoma resection in our hospital from January 2015 to April 2021. Multiple reconstruction techniques such as dura suture, bone reconstruction and PNSF, and related factors such as age, sex, body mass index (BMI), diabetes, tumor size and diameter of diaphragmatic defect were recorded and introduced to multivariate regression to analyze the effects of the above factors on the duration of postoperative cerebrospinal fluid rhinorrhea and bed rest time, with a special focus on the weight priority of dura suture, bone reconstruction, and PNSF. 【Results】 A total of 281 patients were included, with the average age of (47±12.6) years, males accounting for 52.6%. There were 93 cases of PNSF, 268 cases of bone reconstruction, 109 cases of dura anchor suture, 50 cases of patch suture, and 122 cases without suture. The results of multivariate analysis indicated that the application of PNSF, bone reconstruction, and dura suture significantly reduced postoperative rhinorrhea time [reduced by 18.524, 35.876, and 16.983/19.791 (anchor suture/patch suture) hours, respectively; all PPNSF>bone reconstruction [Standard β=0.211/0.207 (anchor suture/patch suture)>0.200>0.165]. The weight of reducing bed time was bone reconstruction >dura suture > PNSF [Standard β=0.239>0.206/0.210 (anchor suture/patch suture) >0.164]. After stabilizing the learning curve in 25-30 cases, the average time for bone reconstruction was (3.9±0.4) minutes. After stabilizing learning curve in 30-40 cases, the dura suture technique took an average of (3.7±0.3) minutes per stitch, (3.7±1.0) stitches per case, and (13.6±2.7) minutes of total time consumption per case. 【Conclusion】 Dural anchoring and patching suture can both effectively shorten the duration of cerebrospinal fluid rhinorrhea and bed rest time. Bone reconstruction significantly improves the stability of reconstruction, especially in prompting patients’ early disengagement of bed rest. Moreover, the learning curves of the above two methods are economical and reasonable, and their weight is close to or even exceeds that of PNSF. Therefore, they can be an effective supplement or even substitute for PNSF.
