Abstract INTRODUCTION Cranial base development plays a large role in anterior and vertical maxillary growth through age 7, and the effect of early endonasal cranial base surgery on midface growth is unknown. We present our experience with pediatric endoscopic endonasal surgery and long-term midface growth. METHODS This is a retrospective review (2000-2016). Pediatric patients were grouped by age at first endoscopic endonasal skull base surgery (<7 yo and >7 yo). Included patients had both pre- and post-operative (>1 yr) imaging. Radiologists performed measurements (Sella-Nasion distance and angles from S-N to maxilla and mandible (SNA, SNB, ANB)), which were compared to age- and sex-matched Bolton standards. Z score test was used; significance was set at P < 0.05. RESULTS >The <7 yo group had 11 patients, averaging follow-up of 5 yrs; the >7 yo group had 33 patients. Most tumors were benign; one patient with a panclival AVM was a significant outlier for all measurements. Comparing the <7 yo group to Bolton standard norms, there was no significant difference in post-operative SNA (P = 0.10), SNB (P = 0.14), or ANB (0.67). SN distance was reduced both pre- and post-operatively (SD = 1.5, P = 0.01 and P = 0.009). Sex had no significant effect. Compared to patients who had surgery in the >7 yo group, the <7 yo group demonstrated no significant difference in pre- to post-operative changes with regard to S-N (P = 0.87), SNA (P = 0.89), and ANB (P = 0.14). Tumor type (craniopharyngioma, angiofibroma, and other types) had no significant effect in either age group. CONCLUSION Though our cohort of patients with skull base tumors demonstrate some abnormal measurements before their operation, their post-operative cephalometrics fall within normal standard deviations and generally have no significant difference compared to patients who underwent operations at an older age. Therefore, there appears to be no evidence of impact of endoscopic endonasal skull base surgery on craniofacial development within the growth period studied.

OBJECTIVECranial base development plays a large role in anterior and vertical maxillary growth through 7 years of age, and the effect of early endonasal cranial base surgery on midface growth is unknown. The authors present their experience with pediatric endoscopic endonasal surgery (EES) and long-term midface growth.METHODSThis is a retrospective review of cases where EES was performed from 2000 to 2016. Patients who underwent their first EES of the skull base before age 7 (prior to cranial suture fusion) and had a complete set of pre- and postoperative imaging studies (CT or MRI) with at least 1 year of follow-up were included. A radiologist performed measurements (sella-nasion [S-N] distance and angles between the sella, nasion, and the most concave points of the anterior maxilla [A point] or anterior mandibular synthesis [B point], the SNA, SNB, and ANB angles), which were compared to age- and sex-matched Bolton standards. A Z-score test was used; significance was set at p < 0.05.RESULTSThe early surgery group had 11 patients, with an average follow-up of 5 years; the late surgery group had 33 patients. Most tumors were benign; 1 patient with a panclival arteriovenous malformation was a significant outlier for all measurements. Comparing the measurements obtained in the early surgery group to Bolton standard norms, the authors found no significant difference in postoperative SNA (p = 0.10), SNB (p = 0.14), or ANB (0.67) angles. The S-N distance was reduced both pre- and postoperatively (SD 1.5, p = 0.01 and p = 0.009). Sex had no significant effect. Compared to patients who had surgery after the age of 7 years, the early surgery group demonstrated no significant difference in pre- to postoperative changes with regard to S-N distance (p = 0.87), SNA angle (p = 0.89), or ANB angle (p = 0.14). Lesion type (craniopharyngioma, angiofibroma, and other types) had no significant effect in either age group.CONCLUSIONSThough our cohort of patients with skull base lesions demonstrated some abnormal measurements in the maxillary-mandibular relationship before their operation, their postoperative cephalometrics fell within the normal range and showed no significant difference from those of patients who underwent operations at an older age. Therefore, there appears to be no evidence of impact of endoscopic endonasal skull base surgery on craniofacial development within the growth period studied.

Purpose Immediate postoperative imaging is frequently obtained after combined skull base surgery (SBS) with endoscopic endonasal and open transcranial approaches. The importance of early postoperative imaging for detecting complications in these patients is still debatable. In this study, we investigated the clinical utility of early postoperative imaging after combined SBS for determination of postoperative complications. Methods A retrospective chart analysis of 21 cases of combined SBS between 2009 and 2015 was performed. Data on postoperative computed tomography (CT) and magnetic resonance imaging (MR), and the hospital course were collected. We separated interpretations of postoperative imaging into two groups: (1) when using the radiologist's interpretation alone, and (2) when using the surgeon's knowledge of the case in conjunction with imaging. Results Forty-two postoperative scans were obtained (21 CT, 21 MR) within 48 hours of surgery. There was a significant statistical difference between imaging interpretation by surgeons and radiologists for CT interpretation only. For CT interpretation the true positive (TP), false positive (FP), true negative (TN), and false negative (FN) rates for radiologists (TP, 0/21; FP, 6/21; TN, 11/21; FN, 4/21) slightly deviated from surgeons' interpretation (TP, 1/21 [p = 0.9999]; FP, 0/21 [p = 0.0207]; TN, 17/21 [p = 0.1000]; FN, 3/21 [p = 1.000]). Rates for MRI interpretation by both groups were nearly identical, with no significant difference found. Overall, four patients experienced seven postoperative complications, which led to a complication rate of 19.0% (4/21). The patients exhibited clinical symptoms in all instances of postoperative complications that required further intervention. Conclusion The benefit of early postoperative imaging to detect complications after combined SBS was limited. In this cohort of patients, positive imaging findings' effects on patient management were dictated by the presence of supporting clinical symptoms.

Abstract Objective Patients undergoing endoscopic endonasal surgery have historically been restricted from using straws postoperatively, due to the concern that this activity generates negative pressure. The objective of this study is to evaluate the pressure dynamics in the sinonasal cavity associated with the use of a straw. Methods Intracranial pressure catheters were placed in the nasal cavity of 20 healthy individuals. Pressure measurements were then recorded while participants drank liquids of different viscosities from a cup and from a straw. Measurements were recorded with and without subjects occluding their nose to simulate postoperative nasal obstruction. Results The average pressure in the nasal cavity while drinking water from a cup was −0.86 cmH2O, from a straw was −1.09 cmH2O, and while occluding the nose and using a straw was −0.81 cmH2O. The average pressure in the nasal cavity while drinking a milkshake from a cup was −0.98 cmH2O, from a straw was −1.88 cmH2O, and while occluding the nose and using a straw was −1.37 cmH2O. There was no statistically significant difference in pressure measurements when comparing either task or consistency (p > 0.05). Conclusion Straw use is not associated with the generation of significant negative pressure in the nasal cavity. The pressure generated when drinking from a straw is not significantly different from that of drinking from a cup. This data suggest that straw use may be safe for patients following endoscopic skull base surgery, but further investigation is warranted.

Anterior skull base (ASB) schwannomas are extremely rare and can often mimic other pathologies involving the ASB such as olfactory groove meningiomas, hemangiopericytomas, esthesioneuroblastomas, and other malignant ASB tumors. The mainstay of treatment for these lesions is gross-total resection. Traditionally, resection for tumors in this location is performed through a bifrontal transbasal approach that can involve some degree of brain retraction or manipulation for tumor exposure. With the recent advances in endoscopic skull base surgery, various ASB tumors can be resected successfully using an expanded endoscopic endonasal transcribriform approach through a “keyhole craniectomy” in the ventral skull base. This approach represents the most direct route to the anterior cranial base without any brain retraction. Tumor involving the paranasal sinuses, medial orbits, and cribriform plate can be readily resected. In this video atlas report, the authors demonstrate their step-by-step techniques for resection of an ASB olfactory schwannoma using a purely endoscopic endonasal transcribriform approach. They describe and illustrate the operative nuances and surgical pearls to safely and efficiently perform the approach, tumor resection, and multilayered reconstruction of the cranial base defect.
