Objectives: Hospital-acquired catheter-associated urinary tract infections (UTIs) have been regarded as preventable adverse events, yet their risk in endoscopic skull base surgery (ESBS) has not been well described despite common use. We determine the incidence of UTI following ESBS and identify contributing clinical factors.
Methods: Retrospective review was conducted for a cohort of 229 consecutive adult patients who underwent endoscopic endonasal surgery for treatment of any skull base pathology between July 2018 and June 2022 at a tertiary academic skull base surgery program. Postoperative UTI comprised the primary outcome. Independent variables included patient demographics, use and length of urinary catheterization, and pre-existing genitourinary conditions.
Results: Nosocomial UTIs were identified in 1.3% (3/229) of patients, occurring on postoperative days 2, 9, and 14, respectively; all were catheter-associated. Overall, 86.0% (197/229) of patients received urinary catheters (mean duration 2.2 ± 1.8 days). Compared to those without, patients with UTI were older (70.0 ± 15.4 vs. 52.2 ± 16.8 years, = 0.034), had lengthier stays (94.7 ± 126.8 vs. 5.9 ± 8.4 days, < 0.001), and had prolonged catheterizations (9.3 ± 5.5 vs. 2.1 ± 1.5 days, < 0.001). Preoperative genitourinary conditions were also associated with UTI development, namely, chronic urinary retention/obstruction (66.7% vs. 4.0%, = 0.006), urinary incontinence (66.7% vs. 6.2%, = 0.013), prostate disease (100.0% vs. 17.8%, = 0.035), and renal dysfunction (100.0% vs. 9.7%, = 0.001). Among intraoperative cerebrospinal fluid leak patients, postoperative CSF leak incidence was not associated with catheter use versus nonuse (3.3% vs. 12.5%, = 0.276).
Conclusion: Although UTIs are uncommon in ESBS patients, advanced age, length of stay, duration of indwelling urinary catheterization, and comorbid genitourinary conditions may elevate risk.

Pituitary neuroendocrine tumors (PitNETS) are common intracranial tumors, but extrasellar or ectopic PitNETS are very rare and supposed to originate from some pituitary remnants. They are mostly found in sphenoidal sinus. But particularly, ectopic clival PitNETS are highly aggressive and can cause bone invasion and can be misdiagnosed as other lesions of the skull base such as chordomas.

Vestibular deficits are common and debilitating, and many patients struggle with dynamic balance, even after treatment with standard rehabilitation techniques. The objective of this study was to measure changes in computerized dynamic posturography sensory ratio information after computerized vestibular retraining therapy (CVRT). This prospective, single-group, interventional study enrolled adult participants with stable, unilateral vestibular deficits.

Unlabelled: Background: Petrous bone cholesteatoma (PBC) is a challenging condition involving the development of an epidermoid cyst within the petrous portion of the temporal bone. Advances in radiological imaging and skull base surgery have refined the management of PBC. Methods: An ambispective descriptive study was conducted on patients diagnosed with PBC between 2021 and 2024.

Pituitary adenomas, the second most common intracranial pathology, often exhibit symptoms beyond the classic triad of headache, visual disturbances, and hormonal imbalances. Unusual presentations involve sinonasal pathology, cranial nerve involvement, and mass effects on adjacent structures like the skull base. Secretory adenomas may manifest hormonal changes and their effects.
