057). On multivariate analysis, HHG and positive node status predicted for worse OS and only HHG predicted for worse DFS. Of note, five patients (all Kadish stage A) who received surgical resection alone had no observed deaths or recurrences with a median follow-up of 44 months (range 5-235 months). Conclusion In this retrospective cohort, patients with positive nodes or HHG have significantly worse clinical outcomes. Future studies should explore treatment intensification for HHG or positive nodes.Patient-centered care is defined as "care that is consistent with and respects the values, needs, and wishes of patients" and is best achieved when clinicians involve patients and their support system in health care discussions and decisions. Tanespimycin ic50 While this approach has been well established and supported in more general medical specialties, such as primary care, that may encompass a more holistic approach, it has rarely been described in surgical disciplines. Acoustic neuromas (ANs) can be unique among other skull base and intracranial pathologies, in that the management of these tumors can vary from patient to patient depending on various factors. Moreover, typical options, including observation, radiation, and surgery, may often have equipoise for some patients and their tumors. Therefore, a patient-centered approach, strongly guided by the expertise of experienced skull base surgeons, may likely be the most appropriate type of care for patients with ANs. Herein, we review the documented use of patient-centered care in other aspects of medicine, propose the benefits of this approach for patients with ANs, and provide ways this can be better implemented in practice.This report introduces a new closure technique for the management of intraoperative cerebrospinal fluid (CSF) leakage during endoscopic endonasal surgery. The procedure is based on the combination of a traditional autologous tissue flap with a heterologous fibrin graft (TachoSil). We performed a retrospective analysis on 121 patients with pituitary adenomas treated in our center by the senior neurosurgeon (author V.R.B) in the previous 4 years. Only one patient (0.8%) developed a CSF leakage and no adverse events were found related to the use of TachoSil. Compared with other techniques used previously, sellar diaphragm reconstruction with TachoSil seems to be an effective and inexpensive alternative.Objective To compare outcome data for surgical approaches in the management of a middle cranial fossa encephalocele or cerebrospinal fluid (CSF) leak and, secondarily, to evaluate the role of obesity and the etiology of the defect. Design Retrospective Setting Quaternary referral center Participants The study included 73 patients who underwent surgical repair of middle cranial fossa tegmen defects, two of which underwent bilateral repair. Outcome Measures Demographic characteristics, clinical presentation, etiology, imaging, audiometry, surgical findings, method and material for repair, and postoperative course. Results Fifty cases were spontaneous in origin, 2 were iatrogenic, and 23 were because of chronic otitis media. Of the 50, 18 underwent middle fossa craniotomy, 29 underwent a transmastoid approach, and 28 underwent a combined approach for repair. A postoperative CSF leak was seen in five patients one who had undergone a transmastoid approach and four after a combined approach. There was no significant difference between the three approaches and risk of postoperative CSF fistulae. Two of the CSF fistulae resolved after a lumbar drain, and the remaining three patients required revision surgery. Conclusions Middle cranial fossa tegmen defects are most commonly seen in obese females and are spontaneous in origin. The most common location was the tegmen mastoideum, and these defects were most commonly repaired through the transmastoid approach, with no greater risk of recurrence.Introduction Olfactory groove meningiomas (OGMs) are often associated with loss of smell following resection. Loss of smell has a measurable impact on quality of life. Smell preservation has been previously described in open approaches for early stage or unilateral OGMs. Evidence of smell preservation in endoscopic approaches is lacking. Design A multi-institutional retrospective review was performed on consecutive patients who underwent unilateral endoscopic endonasal resection of OGM. A gross total resection was achieved with preservation of the contralateral olfactory cleft and bulb. Olfactory function was assessed with a six-point olfactory symptom score and the Sniffin' Sticks 12-item smell identification test (SS-12). Contralateral olfactory bulb volume was measured on postoperative magnetic resonance imaging. Results Four patients (age 42.0 ± 7.5, 75% female) were assessed. Olfactory function was assessed at 21.8 ± 5.6 months following surgery. All patients reported some degree of smell preservation (75% described a slight/mild impairment in smell or better). Olfactory identification was preserved with an SS-12 score of 9 ± 1.4 (anosmia defined as ≤6). The olfactory bulb volume was calculated to be 47.4 ± 15.9 mm 3 (normal >40 mm 3 ). Conclusion Smell preservation is possible following unilateral endoscopic endonasal resection of carefully selected OGM.Introduction Preoperative high-resolution computed tomography (HRCT) is essential in patients undergoing transsphenoidal surgery to identify potential high-risk anatomic variations. There is no consensus in the literature, as to which grading system to use to describe these variants, leading to inconsistent terminology between studies. In addition, substantial variability exists in the reported incidence of anatomic variants. In this study, we performed an institutional imaging analysis and literature review with the objective of consolidating and clearly defining these sphenoid sinus anatomical variations. In addition, we highlighted their surgical implications and propose a checklist for a systematic assessment of the sphenoid sinus on preoperative CT. Methods Review of the literature and retrospective analysis assessing several imaging parameters in 81 patients who underwent preoperative HRCT imaging for endoscopic transsphenoidal tumor resection from January 2008 through July 2015 at Rush University Medical Center.
