Background: Several sellar reconstruction algorithms stratify patients based on risk of postoperative cerebrospinal fluid (CSF) leak. Many proposed algorithms employ techniques that are overly complex and confer morbidity. We review our experience with sellar reconstruction following transsphenoidal pituitary surgery and propose a highly effective, yet simple and low morbidity, algorithm. Methods:A retrospective review of 582 patients who underwent transsphenoidal surgery for pituitary adenoma by a single neurosurgeon between 2005 and 2020 was performed. Patients without an intraoperative CSF leak and without a patulous diaphragm were repaired with an oxidized cellulose onlay (group 1).Patients with a low-flow intraoperative CSF leak or a patulous diaphragm were repaired with a synthetic dural substitute inlay (group 2). Patients with a persistent leak around the inlay repair or a high-flow leak were reconstructed with a synthetic dural substitute inlay and a nasoseptal flap onlay (group 3). Results: There was an overall leak rate of 1.5% (9/582) to 1.0% (2/197) in group 1, 1.7% (6/347) in group 2, and 2.6% (1/38) in group 3. Group 3 had the highest rate of postoperative morbidity, including sinusitis (23.7% vs. 8.6% and 15.0% in groups 1 and 2, p = 0.018) and crusting (42.1% vs. 4.6% and 6.3% in groups 1 and 2, p < 0.001). All techniques healed equally well radiographically. Conclusion:The proposed algorithm for sellar reconstruction is highly effective and minimizes complexity and morbidity, primarily utilizing single-layer reconstructions without the addition of packing material or lumbar drainage.

IMPORTANCE Erich arch bars, 4-point fixation, and bone-supported arch bars are currently used in maxillomandibular fixation, although to what extent they differ in terms of overall charges and clinical outcomes has yet to be reported. OBJECTIVE To determine the association of Erich arch bars, 4-point fixation, and bone-supported arch bars in maxillomandibular fixation with hospital charges and clinical outcomes.
