Risk of incisional recurrence after midface and anterior skull base surgery in sinonasal malignancies.

ABSTRACT: We sought to determine the risk of tumor incisional recurrence in patients receiving surgery and postoperative radiation therapy for locally advanced sinonasal malignancies. Medical records for 70 patients newly diagnosed with nonmetastatic American Joint Committee on Cancer stage II to stage IV sinonasal malignancies between 1991 and 2003 were retrospectively reviewed. Patient demographics and tumor variables were recorded. All patients underwent upfront surgical resection with postoperative three-dimensional conformal proton beam radiotherapy. Recurrence and survival-related outcomes were recorded. Two patients with squamous cell carcinoma had pathologically confirmed tumor recurrence at the incision site. The actuarial risk of incisional recurrence for the entire group at 1 year was 3%. One of the two patients had a maxillary sinus tumor and developed isolated skin recurrence along the transfacial incision. The other patient with an ethmoid sinus tumor developed isolated dural recurrence along the craniotomy incision. Both patients underwent multiple courses of salvage surgery and radiation therapy. One was successfully salvaged locally but developed distant metastases and the other died of local recurrence. Tumor seeding following transfacial and craniotomy surgery can occur, especially for squamous cell carcinoma. Sound oncological surgical technique, even when utilizing these difficult surgical approaches, is important to minimize incisional recurrence.

Mental Health Disorders Associated with Sinonasal and Skull Base Malignancies: A Large Cohort Study.

Project description:Objective The main purpose of this article is to examine the prevalence, incidence, sociodemographic, and clinical characteristics of mental health disorders (MHDs) among patients with skull base malignancies. Design Retrospective cohort study. Settings/Participants Six-thousand seven-hundred sixty sinonasal/skull base cancer patients in the MarketScan database between 2005 and 2014. Main Outcome Measures Frequency of MHDs pre- and post-diagnosis in patients harboring sinonasal/skull base malignancies. Results A significant increase in MHDs was noted from pre- to post-cancer diagnosis (22 vs 31%, p < 0.0001). Despite an increase in the prevalence rate, the demographic profile of patients with MHDs post-diagnosis remained similar to pre-diagnosis. Those patients harboring MHDs were, however, more likely to be women (62.7 vs 47.4%), and carry a history of smoking (40.9 vs 26.3%) than those without MHDs. These comparisons were statistically significant ( p < 0.0001). Conclusion The prevalence of MHDs increases following a diagnosis of a sinonasal/skull base malignancy. Patients with MHDs were more likely to be women and smokers.

Quality-of-Life after Anterior Skull Base Surgery: A Systematic Review.

Project description:Background?Improved treatment and survival of patients with skull base tumors has made the assessment of quality-of-life (QoL) in this population increasingly important. This article provides a comprehensive systematic review pertaining to QoL assessment in adults undergoing anterior skull base surgery. Methods?We performed a literature search using the electronic databases of Ovid Medline and Embase. Additional articles were identified through a search using the phrase anterior skull base. Further articles were sought through hand-searching relevant journals and reference lists of identified articles. Results?Our search strategy identified 29 articles for inclusion in our systematic review, with considerable variation between studies in population characteristics, methodological design and quality, follow-up length, and outcome assessment. The most commonly used QoL tools were the Karnofsky Performance Status and the Anterior Skull Base Questionnaire. QoL following anterior skull base surgery appears to improve beyond preoperative levels in the months after surgery. For patients undergoing endoscopic skull base surgery, the gain in QoL appears to be greater and may manifest earlier, with no clear long-term deleterious effect on sinonasal outcomes compared with open surgery. Conclusions?QoL after anterior skull base surgery in adults appears to improve within several months of surgery, but earlier and to a larger extent if the endoscopic approach is used. Given the relative paucity and heterogeneity of anterior skull base tumors, large-scale prospective multicentre studies utilizing valid and reliable multidimensional QoL tools are required. This may result in improved patient care, by understanding patients' needs better and facilitating the provision of reliable outcome data for clinical trials.

Modifications to the endoscopic approach for anterior skull base lesions improve postoperative sinonasal symptoms.

Project description:Background/Objective Our institution previously showed that patients experience significant postoperative sinonasal symptoms for the first few months after endoscopic transnasal transsphenoidal skull base surgery (eTNTS). Since our initial study we have modified our technique, discontinuing routine resection of the middle turbinate, maxillary antrostomies, and nasoseptal flaps. In this study, we analyze whether these technical modifications decrease postoperative sinonasal morbidity after eTNTS. Methods A retrospective review was performed of 93 consecutive patients who underwent eTNTS at a tertiary academic medical center from August 2011 to August 2012. Main Outcome Measures Sino-Nasal Outcome Test (SNOT)-20 and SNOT-22 scores preoperatively and after surgery. Results Compared with our previous study, our new cohort experienced a significant improvement (p < 0.05) in SNOT scores for the need to blow nose, runny nose, postnasal discharge, thick nasal discharge, wake up at night, reduced concentration, and frustrated/restless/irritable. Within the new cohort, patients who did not have a nasoseptal flap or middle turbinate resection had less worsening and faster improvement of nasal symptom scores after surgery. Conclusions Preserving normal sinonasal physiology during eTNTS by limiting middle turbinate resections, avoiding unnecessary maxillary antrostomies, and reducing the use of nasoseptal flaps when feasible results in less sinonasal morbidity and more rapid recovery during the postoperative period.

A new radiological classification for the risk assessment of anterior skull base injury in endoscopic sinus surgery.

Project description:Keros and Gera classifications are widely used to assess the risk of skull base injury during endoscopic sinus surgery. Although, both classifications are useful preoperatively to stratify risk of patients going for surgery, it is not practical to measure the respective lengths during surgery. In this study, we aimed to propose a new radiological classification (Thailand-Malaysia-Singapore (TMS)) to assess the anatomical risk of anterior skull base injury using the orbital floor (OF) as a reference. A total of 150 computed tomography images of paranasal sinuses (300 sides) were reviewed. The TMS classification was categorized into 3 types by measuring OF to cribriform plate and OF to ethmoid roof. Most patients were classified as TMS type 1, Keros type 2 and Gera class II, followed by patients classified as TMS type 3, Keros type 1 and Gera class 1. TMS has significant correlation with Keros classification (p?<?0.05). There was no significant correlation between Keros and Gera classifications (p?=?0.33) and between TMS and Gera classifications (p?=?0.80). The TMS classification has potential to be used for risk assessment of skull base injury among patients undergoing ESS. It serves as an additional assessment besides the Keros and Gera classifications.

Minimally invasive surgery of the anterior skull base: transorbital approaches.

Project description:Minimally invasive approaches are becoming increasingly popular to access the anterior skull base. With interdisciplinary cooperation, in particular endonasal endoscopic approaches have seen an impressive expansion of indications over the past decades. The more recently described transorbital approaches represent minimally invasive alternatives with a differing spectrum of access corridors. The purpose of the present paper is to discuss transorbital approaches to the anterior skull base in the light of the current literature. The transorbital approaches allow excellent exposure of areas that are difficult to reach like the anterior and posterior wall of the frontal sinus; working angles may be more favorable and the paranasal sinus system can be preserved while exposing the skull base. Because of their minimal morbidity and the cosmetically excellent results, the transorbital approaches represent an important addition to established endonasal endoscopic and open approaches to the anterior skull base. Their execution requires an interdisciplinary team approach.

Endoscopic anterior skull base surgery: intraoperative considerations of the crista galli.

Project description:We sought to measure the anatomic dimensions of the crista galli in a consecutive series of patients undergoing the endoscopic transcribriform approach for anterior skull base tumors at a tertiary academic university hospital. We performed a retrospective chart review of patients undergoing purely endoscopic transcribriform surgery for sinonasal and skull base lesions. Main outcome measures included radiological dimensions of the crista galli. A total of 12 patients were identified and treated by the senior authors at the University of Pennsylvania. The average crista galli dimensions were 12.7 ± 2.4 mm (anterior-posterior) and 12.9 ± 2.5 mm (cranial-caudal dimension). Knowledge of the dimensions of the crista galli is important in preoperative planning for both instrumentation and access.

Perioperative Considerations in Endoscopic Skull Base Surgery.

Project description:Purpose of the Review:Present an overview of perioperative considerations specific to endoscopic skull base surgery necessary to maximize successful outcomes. Recent Findings:The majority of perioperative considerations for endoscopic skull base surgery lack strong supporting evidence and frequently have varied use or implementation amongst institutions. A notable exception comes from a recent randomized controlled trial demonstrating the benefit of lumbar drainage in high-risk cerebrospinal fluid leaks. Summary:Skull base surgeons must consider a multitude of perioperative factors. While many components of perioperative management are extrapolated from related fields such as endoscopic sinus surgery or open cranial base surgery, additional high-quality studies are needed to delineate best practices specific to endoscopic skull base surgery.

Computer assisted skull base surgery: a contemporary review.

Project description:Skull base surgery has evolved significantly since Harvey Cushing's first descriptions in the early 1900s. Computer aided surgery (CAS) applications continue to expand; they include virtual surgical planning, augmented and virtual reality, 3D printing of models/cutting guides/implants, surgical navigation, and intraoperative imaging. The authors will review the current skull base CAS literature and propose a computer aided surgical workflow categorizing these applications into 3 phases: 1) Virtual planning, 2) Surgical execution, 3) Intraoperative verification.

Venous thromboembolism chemical prophylaxis after skull base surgery.

Project description:PurposeThere is no guidance surrounding postoperative venous thromboembolism (VTE) prophylaxis using pharmacological agents (chemoprophylaxis) in patients undergoing skull base surgery. The aim of this study was to compare VTE and intracranial haematoma rates after skull base surgery in patients treated with/without chemoprophylaxis.MethodsReview of prospective quaternary centre database including adults undergoing first-time skull base surgery (2009-2020). VTE was defined as deep vein thrombosis (DVT) and pulmonary embolism (PE) within 6 months of surgery. Multivariate logistic regression was used to determine factors predictive of postoperative intracranial haematoma/VTE. Propensity score matching (PSM) was used in group comparisons.ResultsOne thousand five hundred fifty-one patients were included with a median age of 52 years (range 16-89 years) and female predominance (62%). Postoperative chemoprophylaxis was used in 81% of patients at a median of 1 day postoperatively. There were 12 VTE events (1.2%), and the use of chemoprophylaxis did not negate the risk of VTE entirely (p > 0.99) and was highest on/after postoperative day 6 (9/12 VTE events). There were 18 intracranial haematomas (0.8%), and after PSM, chemoprophylaxis did not significantly increase the risk of an intracranial haematoma (p > 0.99). Patients administered chemoprophylaxis from postoperative days 1 and 2 had similar rates of intracranial haematomas (p = 0.60) and VTE (p = 0.60), affirmed in PSM.ConclusionPostoperative chemoprophylaxis represents a relatively safe strategy in patients undergoing skull base surgery. We advocate a personalised approach to chemoprophylaxis and recommend it on postoperative days 1 or 2 when indicated.

Image-guided robotic skull base surgery.

Project description:Objectives To describe the potential uses of computed tomography image guidance in concert with the surgical robot for skull base surgery. Design An anatomical study was conducted. Setting Tertiary academic center. Participants Cadaveric skull. Main Outcome Measures The primary outcome measure was to measure the accuracy of robotic arm positioning to anatomical landmarks on a skull using image guidance and the surgical robot synchronously. Instruments with different angles of rotations were used. Estimated systematic error was calculated and compared with achieved errors. Clinical applications of metachronous image guidance and robotic system were discussed. Results The skull model approximated < 1 mm accuracy using standard image guidance instruments and the 0-degree robotic arm positioning. Increased angles of instruments from 20 to 60 degrees on the robotic system revealed more significant increases in error than estimated. Conclusions Image guidance may be useful for transoral robotic approaches. Precise movements are improved by limiting the angle of deviation. Future studies will help optimize the combined technologies before validating the study in clinical settings.
