RESUMO
Background: Rates of spontaneous cerebrospinal fluid leak (sCSF) repairs have increased in recent decades in line with increases in obesity rates. Objectives: To determine if the national rate of sCSF leak has continued to rise in recent years and to identify associated risk factors utilizing a comprehensive national database comprising most academic medical centers. Methods: A retrospective review from 2009 to 2018 was performed using the Vizient Clinical Database (CDB) of 105 leading academic medical centers in the United States. Patients who underwent CSF leak repair in the CDB database using ICD-9 and ICD-10 diagnostic and procedure codes. Patients with epidural hematomas over the same time frame were used as a control. National rates of craniotomy for sCSF leak repair each quarter were assessed and sCSF leak patient characteristics (age, gender, obesity, hypertension, diabetes) were calculated. Results: The rate of craniotomy for all sCSF leak repairs increased by 10.2% annually from 2009 to 2015 (P < 0.0001). There was no statistically significant change in the rate of epidural hematomas over the same period. The rate of lateral sCSF leak repair increased on average by 10.4% annually from 2009 (218 cases/year) to 2018 (457 cases/year) (P < 0.0001). A statistically significant increase was observed across all regions of the United States (P ≤ 0.005). sCSF leak patients had an average (standard deviation) age of 55.0 (13.2) years and 67.2% were female. Obesity was the only demographic factors that increased significantly over time. Likely due to comorbid factors, Black patients comprise a disproportionately large percentage of lateral sCSF leak repair patients. Conclusions: The rate of craniotomy for spontaneous CSF leaks continues to rise by approximately 10% annually.
RESUMO
OBJECTIVES/HYPOTHESIS: To conduct longitudinal postoperative follow-up and discern health-related quality-of-life (HR-QoL) changes using a validated questionnaire among patients undergoing head and neck surgeries during a short-term, global surgical trip in a resource-limited setting. To identify clinicodemographic predictors of post-operative HR-QoL improvements in this setting. STUDY DESIGN: Retrospective observational study with prospective follow-up. METHODS: Patients undergoing surgery at Moi Teaching and Referral Hospital in Eldoret, Kenya through the authors' short-term surgical trip (STST) between 2016 and 2019 were asked to complete preoperative Short Form-36 (SF-36) HR-QoL questionnaires, and postoperative SF-36 questionnaires during subsequent follow-up. Preoperative and postoperative SF-36 domain scores, and two composite scores (mental component summary [MCS] and physical component summary [PCS]) were compared. Linear regression models were fit to identify clinicodemographic factors predictors of general health (GH), MCS, and PCS scores. RESULTS: Among the 26 participating patients, significant improvements were seen in post-operative GH (mean change = 19.8) and MCS (mean change = 11.2) scores. Lower pre-operative GH, MCS, and PCS scores were predictive of greater improvement in the corresponding post-operative scores. Longer time to follow-up was associated with greater improvement in GH score. Mean follow-up interval was 23.1 months (SD = 1.8 months). CONCLUSIONS: Utilizing the SF-36 questionnaire, we found that patients' perception of their general and psychosocial health improved after undergoing head and neck surgeries through a global STST. This study provides important, preliminary evidence that that elective surgeries performed in low-resource settings convey substantial benefit to patient QoL. LEVEL OF EVIDENCE: 4 Laryngoscope, 131:2006-2010, 2021.

OBJECTIVE: Temporal bone spontaneous cerebrospinal fluid (sCSF) leaks are characterized by defects in the tegmen along with calvarial thinning without associated thinning of the extracranial zygoma. The authors sought to determine the effect of age and race on calvarial, tegmen, and zygoma thickness. STUDY DESIGN: Retrospective cohort study. SETTING: Tertiary Referral Center. PATIENTS: A total of 446 patients with high-resolution head computer tomography (CT) imaging from 2003 to 2018.Intervention(s): Calvarial, tegmen, and zygoma thicknesses were measured using 3D slicer.Main Outcome Measure(s): Effects of age and race on calvarium, tegmen, zygoma thickness. RESULTS: Among all patients, increased age was associated with increased thickness of the calvarium [95% CI, 0.0002 to 0.007 mm/year, Pâ<â0.05] and tegmen [95% CI, 0.00039 to 0.0075âmm/year, Pâ=â0.03], but decreased thickness of the zygoma [95% CI, -0.013 to -0.005âmm/year, Pâ<â0.001]. When compared to white patients, black patients had thicker mean [SD] calvaria (2.63 [0.61] versus 3.30 [0.79] mm; difference, 0.67âmm; [95% CI, 0.57 to 0.77]; Cohen d, 1.02), tegmen (0.73 [0.34] versus 0.92 [0.36] mm; difference 0.19âmm; [95% CI, 0.101 to 0.279]; Cohen d, 0.533) and zygoma (4.89 [0.81] versus 5.55 [0.91] mm; difference, 0.66âmm; [95% CI, 0.53 to 0.79]; Cohen d, 0.78). CONCLUSIONS: Racial differences exist in calvarial and zygoma thickness. Aging generally leads to increased calvarium and tegmen thickness, suggesting that early onset of obesity and comorbid conditions known to thin the skull base may predispose patients to developing sCSF leaks by reversing the effects of age.

We describe a case of an 81-year-old male presenting with bitemporal visual field defects and blurry vision in the right eye. The patient was found to have a recurrent primary paraganglioma in the sellar and suprasellar region requiring a repeat transsphenoidal endoscopic resection. Immunohistochemical examination confirmed paraganglioma with the classic zellballen appearance which stained positive for chromogranin, synaptophysin, and S-100 in the periphery. Paragangliomas (PGLs) in the sella turcica are a rare entity; only 19 cases have ever been reported in the literature. PGLs in the sellar region are often misdiagnosed or diagnosed in a delayed fashion. Earlier diagnosis of this locally aggressive tumor and meticulous debulking can prevent morbidity secondary to the tumor's compressive effects. This report highlights the effectiveness of surgical interventions in treatment of paragangliomas. More research is still needed to determine the need for adjuvant therapies such as radiation.
RESUMO
OBJECTIVES: To systematically evaluate the clinico-diagnostic profile and management outcomes of otorhinolaryngologic manifestations of Extranodal Rosai-Dorfman Disease (ENRDD) in the pediatric population. METHODS: The search terms Rosai Dorfman Disease and Sinus Histiocytosis were used to query PubMed, Ovid/Medline, and Scopus databases from inception through September 30, 2018. Studies were systematically reviewed in accordance to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) protocol. All reports of ENRDD involving at least one otorhinolaryngologic subsite in children less than 18 years were eligible for inclusion. RESULTS: A total of 31 studies met inclusion criteria resulting in identification of 31 ENRDD cases with a mean age of 11.5 years. Of the 31 patients, 23 were male (74.2%) and 7 were female (22.6%). Extranodal lesions were limited to otorhinolaryngologic subsites in 24 patients (77.4%), while 7 patients (22.5%) were found to have extranodal lesions simultaneously involving otorhinolaryngologic and nonotorhinolaryngologic sites. The nasal vault was the most common otorhinolaryngologic site involved (n = 13, 41.9%), followed by the paranasal sinuses (n = 10, 32.3%). The most common non-otorhinolaryngologic site that was concurrently involved was the orbit (n = 4, 57.1%). Concurrent cervical lymphadenopathy was present in 19 patients (61.2%). While not documented for 2 cases, emperipolesis on histopathology was confirmed in 29 patients (93.5%). Single therapy with surgical excision was the most common modality of treatment (n = 15, 53.6%) and yielded highest remission rates (80%). In 11 instances (34.36%), ENRDD was misdiagnosed. CONCLUSION: Pediatric ENRDD is a rare disease entity that maintains a high misdiagnosis potential. The most common otorhinolaryngologic location for extranodal manifestation is the sinonasal compartment. Surgical excision remains the most common treatment modality yielding lowest persistence and/or recurrence rates.

OBJECTIVE: Determine if patients with increased opening pressure (OP) on lumbar puncture (LP) have thinner calvaria and skull bases. STUDY DESIGN: Retrospective cohort study. SETTING: Tertiary referral center. PATIENTS: Patients (≥18 yr of age) who had a recorded OP on LP and high-resolution computed tomography imaging of the head. Patient age, sex, body mass index were calculated. Intracranial hypertension (IH) was defined with an OP≥25âcm-H2O and low intracranial pressure with an OP<15âcm-H2O. INTERVENTION: Measurement of calvarial, zygoma, and skull base thickness when blinded to OP with three-dimensional slicer and radiologic calipers. MAIN OUTCOME MEASURES: Association of calvarial, skull base, and zygoma thickness with OP and age. RESULTS: Fifty-eight patients were included with a mean (SD) age of 53.1 (16.2) years and average (SD) body mass index of 30.1 (9.1) kg/m. Patients with IH had thinner mean (SD) calvaria (3.01 [0.81] versus 2.70 [0.58] mm; pâ=â0.036) and skull bases (5.17 [1.22] versus 4.60 [1.42] mm; pâ=â0.043) when compared with patients without IH. The mean (SD) extracranial zygoma thickness was similar between the two groups (5.09 [0.76] versus 5.00 [0.73] mm; pâ=â0.56). General linear model regression demonstrated advancing age was associated with increasing calvarial thickness in patients without IH and calvarial thinning in patients with IH (pâ=â0.038). CONCLUSION: IH is independently associated with intracranial bone (calvaria and skull base) thinning and not extracranial (zygoma) thinning. Skull thinning occurs with IH and advancing age. These findings support a possible role of increased ICP in the pathophysiologic development of spontaneous cerebrospinal fluid leaks.
