Objectives The use of endoscopic approaches for sinonasal malignancy resection has increased, but survival data are limited secondary to disease rarity and new surgical technique. Here we present a systematic review and meta-analysis of endoscopic endonasal resection of sinonasal malignancy. Data Sources MEDLINE, PubMed Central, NCBI Bookshelf, Cochrane Library, clinicaltrials.gov, National Guideline Clearinghouse. Review Methods PRISMA/MOOSE guidelines were followed. MeSH terms were “endoscopic” AND (“esthesioneuroblastoma” OR “sinonasal adenocarcinoma” OR “squamous cell carcinoma” OR “sinonasal undifferentiated carcinoma”). For studies in which individual-level data were available, results were obtained by direct pooling. For studies in which only summary Kaplan-Meier curves were available, numerical data were extracted, traced, and aggregated by fitting a Weibull model. Results Of 320 studies identified, 35 case series were included (n = 952 patients), with 15 studies analyzed via aggregate modeling and 20 studies analyzed via direct pooling. Two- and 5-year survival rates for patients in aggregate modeling were 87.5% and 72.3%, respectively (mean follow-up: 32.9 months). Two- and 5-year survival for patients in direct pooling were 85.8% and 83.5%, respectively (mean follow-up: 43.0 ± 19.5 months). Significant overall survival difference was found between low- and high-grade cancers (P = .015) but not between low- and high-stage cancers (P = .79). Conclusion Overall 2- and 5-year survival rates are comparable and sometimes greater than those from open craniofacial resection. Survival rates significantly differ by cancer grade but not stage. Journals and investigators should be encouraged to publish retrospective and prospective case series with staged survival updates based on established guidelines.

OBJECTIVE To study the role of endoscopic sinus surgery (ESS) in the management of intracranial complications of children with acute rhinosinusitis METHODS: Retrospective chart review at a tertiary care pediatric hospital MAIN OUTCOMES: Demographics, intracranial complications, length of hospital stay (LOS), neurological sequelae, ESS, neurosurgical procedures RESULTS: Twenty-four children with a mean age (SD) of 12.9 years (+/-3.2) with an intracranial complication(s) of acute rhinosinusitis were identified between 2005-2016. A total of 22 were included and 15 (68%) of these were males. The most common complications were: subdural abscess (n=10), epidural abscess (n=10), meningitis (n=5), intraparenchymal abscess (n=5), and cavernous sinus thrombosis (n= 2). Neurologic symptoms included headache (n=12), hemiparesis (n=5) and aphasia (n=3). Average length of stay was 16 (+/- 9.2) days. Average follow up was 7 (+/-5.6) months. One patient had residual seizures and 1 had recurrent rhinosinusitis. Aphasia and hemiparesis resolved in all patients within 1 year. Nineteen (86%) patients had ESS within 4 days of admission. Fourteen patients (63%) had a neurosurgical procedure, 6 (27%) required more than 1 neurosurgical procedure. Six patients (27%) had concurrent neurosurgical drainage and ESS. Four patients (17%) had neurosurgical procedure followed by ESS and 3 patients (13%) were treated only by a neurosurgical procedure. Patients who underwent ESS prior to a neurosurgical procedure had significantly less risk of needing a neurosurgical intervention (OR = .02, p < .01). There was a significantly higher proportion of neurosurgical patients with positive Strep anginosus cultures compared to the ESS only group (85.7% vs 37.5%, p = .02). Studies with larger patient populations are needed to determine the role of ESS in the management of intracranial complications of children with acute rhinosinusitis. DISCUSSION Early ESS may be associated with less need for neurosurgical procedures.

Objective The purpose is to determine the prevalence of electrocardiogram (ECG) abnormalities, including borderline and prolonged QT, among screened children with sensorineural hearing loss (SNHL) and to analyze their subsequent medical workup. Study Design Institutional Review Board–approved case series with chart review. Setting Tertiary academic center. Subjects and Methods Cases from 1996 to 2014 involving pediatric patients (N = 1994) with SNHL were analyzed. Abnormal ECGs were categorized as borderline/prolonged QT or other. A board-certified pediatric cardiologist retrospectively determined the clinical significance of ECG changes. For follow-up analysis, children with heart disease, known syndromes, or inaccessible records were excluded. Results Among 772 children who had ECGs, 215 (27.8%) had abnormal results: 35 (4.5%) with QT abnormalities and 180 (23.3%) with other abnormalities. For children with QT abnormalities meeting inclusion criteria (n = 30), follow-up measures included cardiology referral (46.6%), repeat ECG by ear, nose, and throat (ENT) specialist (20%), clearance by ENT specialist with clinical correlation and/or comparison with old ECGs (20%), and pediatrician follow-up (6.7%). Documentation of further workup by ENT or referral was absent for 6.7%. For children with other ECG changes meeting inclusion criteria (n = 136), abnormalities were documented for 57 (41.9%); normal QT without other abnormality was documented for 18 (13.2%). The most common follow-up referrals were to pediatricians (16.9%) and cardiologists (10.3%). Among patients with clinically significant non-QT abnormalities mandating further evaluation (n = 122), 38 (31.1%) had documented follow-up in medical records. Conclusion There is a high prevalence of ECG abnormalities among children with congenital SNHL. If findings are confirmed by future studies, screening should be considered for congenital unilateral or bilateral SNHL, regardless of severity. We describe a standardized protocol for ECG screening/follow-up.

Objective To highlight key anatomical and technical considerations for facial artery identification, and harvest and transposition of the facial artery buccinator (FAB) flap to facilitate its future use in anterior skull base reconstruction. Only a few studies have evaluated the reverse-flow FAB flap for skull base defects. Design Eight FAB flaps were raised in four cadaveric heads and divided into thirds; the facial arterys course at the superior and inferior borders of the flap was measured noting in which incisional third of the flap it laid. The flaps reach to the anterior cranial fossa, sella turcica, clival recess, and contralateral cribriform plate were studied. A clinical case and operative video are also presented. Results The facial artery had a near vertical course and stayed with the middle (⅝) or posterior third (⅜) of the flap in the inferior and superior incisions. Seven of eight flaps covered the sellar/planar regions. Only four of eight flaps covered the contralateral cribriform region. Lastly, none reached the middle third of the clivus. Conclusions The FAB flap requires an understanding of the facial arterys course, generally seen in the middle third of the flap, and is an appropriate alternative for sellar/planar and ipsilateral cribriform defects.

Importance The use of skull base surgery in patients 70 years or older is increasing, but its safety in this age group has not been evaluated to date. Objectives To describe outcomes in a cohort of patients 70 years or older undergoing skull base surgery and to evaluate whether age, type of disease process, and approach (endoscopic vs traditional open surgery) are associated with increased intraoperative and postoperative complications in this population. Design, Setting, and Participants This retrospective cohort study analyzed a population-based sample of 219 patients 70 years or older from a database of 1720 patients who underwent skull base surgery at University of North Carolina Hospitals, Chapel Hill, a tertiary referral center, between October 2007 and June 2017. Data were collected from June 2016 to July 2017 and analyzed in July 2017 and August 2017. Exposure Skull base surgery. Main Outcomes and Measures Data collected included demographic characteristics, surgical approach, and disease process. Intraoperative findings and postoperative complications were analyzed by age, surgical approach, and malignancy status. Results Of the 219 patients, 166 were aged 70.0 to 79.9 years and 53 patients were older than 80 years (mean [SD] age, 76.4 [4.7] years); 120 (54.8%) were men and 160 (73.7%) were white. There were 161 (73.5%) endoscopic and 58 (26.5%) open operations. The most common pathologic processes among the 219 patients were nonsellar malignant (81 [37.0%]), nonsellar benign (53 [24.2%]), and pituitary (49 [22.4%]) tumors. The most common intraoperative and postoperative complications were intraoperative major bleeding (5 of 219 patients [2.3%]) and postoperative bleeding (9 [4.1%]). Thirty-day mortality was zero. There was no clinically meaningful difference in complications between patients aged 70.0 to 79.9 years vs those older than 80 years, endoscopic vs open surgery, or benign vs malignant neoplasms. Specifically, between the endoscopic and open surgery groups, there was no difference in intraoperative major bleeding (3.9%; 95% CI, −0.7% to 12.9%), postoperative cerebrospinal fluid leak (−0.6%; 95% CI, −3.4% to 5.6%), or postoperative bleeding (1.5%; 95% CI, −3.9% to 10.6%). Conclusions and Relevance Skull base surgery is a safe option in persons 70 years or older, with similar outcomes across age ranges, surgical approaches, and disease processes.
