Abstract
Olfactory neuroblastomas are uncommon malignancies that arise from olfactory receptor cells located high in the nasal cavity. Accurate diagnosis plays a crucial role in determining clinical results and guiding treatment decisions. Diagnosis can be a major challenge for pathologists, especially when dealing with tumours with poor differentiation. The discovery of several molecular and immunohistochemical markers would help to overcome classification difficulties. Due to the paucity of large-scale studies, standardisation of diagnosis, treatment and prediction of outcome remains a challenge. Surgical resection by endoscopic techniques with the addition of postoperative irradiation is the treatment of choice. In addition, it is advisable to consider elective neck irradiation to minimise the risk of nodal recurrence. Molecular characterisation will help not only to make more accurate diagnoses but also to identify specific molecular targets that can be used to develop personalised treatment options tailored to each patient. The present review aims to summarise the current state of knowledge on histopathological diagnosis, the molecular biology and management of this disease.

Abstract
OBJECTIVES We compared the lengths of a nasoseptal flap (NSF) and skull base according to race, age, and sex. METHODS We performed paranasal sinus computed tomography in 19,961 adult patients between 2003 and 2022. The race of the patients was East Asian (n = 71), Caucasian (n = 71), or Middle Eastern (n = 71). The expected lengths of the NSF and anterior skull base defect were measured and analyzed according to race, age, and sex. RESULTS Compared with Caucasians and Middle Easterners, East Asians had a shorter NSF length (p < 0.001) and lower ratio of the expected NSF length to the expected defect length (p < 0.001). There was no difference in the values among age groups. The expected NSF length was longer, and the ratio of the expected NSF length to the expected defect length was higher, in males than females (p < 0.001 for both). CONCLUSIONS East Asians and females had a shorter NSF length and lower ratio of expected NSF to surgical defect lengths after anterior skull base reconstruction compared with the other races and with males, respectively. Anatomical differences should be considered when long NSF lengths are required, such as for anterior skull base reconstruction.

Abstract
BACKGROUND Surgical excision represents the unequivocal treatment modality for symptomatic paranasal sinus osteomas. However, the optimal surgical approach and the extent of the surgery, as well as the management stance in the case of an asymptomatic tumor, remain controversial. METHODS The MeSH terms 'Osteoma', 'Nasal Cavity', and 'Paranasal Sinuses' were used to retrieve articles concerning the management of paranasal sinus osteomas that were published in the last 30 years, the vast majority of which comprised case reports of one or two cases. Original articles or large series of more than six cases were prioritized. RESULTS Our review summarizes previous findings and opinions relevant to the management of symptomatic and asymptomatic paranasal sinus osteomas. The recent shifts in trends of their management are thoroughly discussed. Currently, an extension of the lesion through the anterior frontal sinus wall; an erosion of the posterior wall of the frontal sinus; a far-anterior intraorbital extension; an attachment to the orbital roof beyond the midorbital point; and some patient-specific adverse anatomic variations that may restrict access, are considered strong contraindications to a purely endoscopic approach. On the grounds of this thorough review, a new grading system for frontal and frontoethmoidal osteomas is proposed to allow better conformity to recent advancements and current clinical, research, and educational needs. CONCLUSION Over the past 30 years, endoscopic techniques have emerged as the new standard of care for favorably located paranasal sinus osteomas. Nonetheless, open approaches remain indispensable for the management of the more perplexing cases of frontal sinus osteomas.

Abstract
OBJECTIVE The endoscopic endonasal approach (EEA) has evolved into a mainstay of skull base surgery over the last two decades, but publications examining the intraoperative and perioperative complications of this technique remain scarce. A prior landmark series of 800 patients reported complications during the first era of EEA (1998-2007), parallel to the development of many now-routine techniques and technologies. The authors examined a single-institution series of more than 1000 consecutive EEA neurosurgical procedures performed since 2010, to elucidate the safety and risk factors associated with surgical and postoperative complications in this modern era. METHODS After obtaining institutional review board approval, the authors retrospectively reviewed intraoperative and postoperative complications and their outcomes in patients who underwent EEA between July 2010 and June 2018 at a single institution. RESULTS The authors identified 1002 EEA operations that met the inclusion criteria. Pituitary adenoma was the most common pathology (n = 392 [39%]), followed by meningioma (n = 109 [11%]). No patients died intraoperatively. Two (0.2%) patients had an intraoperative carotid artery injury: 1 had no neurological sequelae, and 1 had permanent hemiplegia. Sixty-one (6.1%) cases of postoperative cerebrospinal fluid leak occurred, of which 45 occurred during the original surgical hospitalization. Transient postoperative sodium dysregulation was noted after 87 (8.7%) operations. Six (0.6%) patients were treated for meningitis, and 1 (0.1%) patient died of a fungal skull base infection. Three (0.3%) patients died of medical complications, thereby yielding a perioperative 90-day mortality rate of 0.4% (4 deaths). High-grade (Clavien-Dindo grade III-V) complications were identified after 103 (10%) EEA procedures, and multivariate analysis was performed to determine the associations between factors and these more serious complications. Extradural EEA was significantly associated with decreased rates of these high-grade complications (OR [95% CI] 0.323 [0.153-0.698], p = 0.0039), whereas meningioma pathology (OR [95% CI] 2.39 [1.30-4.40], p = 0.0053), expanded-approach intradural surgery (OR [95% CI] 2.54 [1.46-4.42], p = 0.0009), and chordoma pathology (OR [95% CI] 9.31 [3.87-22.4], p < 0.0001) were independently associated with significantly increased rates of high-grade complications. CONCLUSIONS The authors have reported a large 1002-operation cohort of EEA procedures and associated complications. Modern EEA surgery for skull base pathologies has an acceptable safety profile with low morbidity and mortality rates. Nevertheless, significant intraoperative and postoperative complications were correlated with complex intradural procedures and meningioma and chordoma pathologies.

Abstract
OBJECTIVES/HYPOTHESIS Olfactory neuroblastoma (ONB) is a rare sinonasal malignant neoplasm that is known to develop late recurrence. The aim of this study is to evaluate the long-term outcomes of patients with ONB and to determine the factors associated with prognosis. STUDY DESIGN Retrospective study. METHODS A retrospective review of the medical records of 139 patients diagnosed with ONB at MD Anderson Cancer Center was performed between 1991 and 2016. Descriptive statistics were calculated, and Kaplan-Meier curves were utilized to assess survival. RESULTS Median follow-up time was 75 months. Overall, 129 patients (92.8%) had surgery as part of their treatment and 82 (58.9%) patients received postoperative radiation therapy (PORT) or concurrent chemoradiotherapy. Endoscopic approaches were utilized for 72 patients, 69.4% of whom had pure endoscopic endonasal approaches. Five-year overall survival and disease-specific survival were 85.6% and 93.4%, respectively. Recurrence rate was 39.6% with a median time to recurrence of 42 months. Among the 31 patients who received elective nodal irradiation (ENI), two patients developed neck recurrence (6.4%) compared with 20 who developed neck recurrence when ENI was omitted (34.4%) (P = .003). Advanced Kadish stage, orbital invasion, intracranial invasion, and presence of cervical lymphadenopathy at the time of presentation were significantly associated with poor survival. CONCLUSION ONB has an excellent survival. Surgical resection with PORT when indicated is the mainstay of treatment. Endoscopic approaches can be used as a good tool. Elective neck irradiation reduces the risk of nodal recurrence among patients with clinically N0 neck. Despite the excellent survival, recurrence rate remains high and delayed, highlighting the need for long-term surveillance. LEVEL OF EVIDENCE Level 4 Laryngoscope, 2021.

Abstract
OBJECTIVE The objective of the present study was to describe and evaluate the feasibility, mobility, and surface area provided by the simple and extended transorbital pericranial flap (TOPF). Furthermore, we compared this novel technique with the current practice of pericranial flap harvesting and insetting techniques. We also studied the adequacy of the TOPF in the reconstruction of postoperative anterior cranial fossa (ACF) defects. METHODS The TOPF was performed bilaterally in 5 alcohol-preserved, latex-injected human cadaveric specimens. The TOPF was harvested in 2 stages: the orbitonasal stage and the cranial stage. For the orbitonasal stage, a transorbital superior eyelid approach was used. We have described 2 harvesting techniques for creating 2 distinct TOPF types (simple and extended) according to the main vascular pedicle. The superficial flap areas offered by the simple and extended TOPF and the traditional bicoronal pericranial flap were calculated and compared. The distances from the supratrochlear and supraorbital arteries to specified anatomical landmarks were also measured. Additionally, the ACF defect area of relevant surgical cases performed using endoscopic transcribriform approaches were measured on immediate postoperative computed tomography head scans using radiological imaging software. RESULTS The harvest of both the simple and the extended TOPFs was efficient. As expected, the areas offered by simple and extended TOPFs were smaller than that offered by the traditional bicoronal flap. However, the surface area offered by either the simple or extended TOPF provides sufficient coverage for most ACF defects. A high spatial distribution was observed between the vascular pedicles and their respective foramen or notch. CONCLUSIONS The TOPF represents a novel harvesting, tunneling, and insetting technique that offers a large, versatile, pedicled flap for coverage of most standard ACF defects after endoscopic surgery.

Abstract
OBJECTIVE The endoscopic endonasal approach (EEA) has been applied in the treatment of olfactory neuroblastoma (ONB). However, there is a lack of research examining the impact of EEA on locally advanced ONB. This study assessed the outcomes of EEA in patients with locally advanced ONB and its impact on the quality of life (QOL). METHODS We retrospectively reviewed patients with Kadish stage C ONB who underwent EEA between December 2004 and October 2019 and assessed demographic data, histopathologic grade, the extent of resection, postoperative complications, and outcomes. Preoperative and postoperative QOL was assessed using the Sino-Nasal Outcome Test. RESULTS Twenty-six patients (18 men, 8 women; aged 26-79 years) were enrolled, with 12 cases of Hyams grade II and III and 1 case of grade I and IV each. In total, 25 patients received radiotherapy and 16 patients received chemotherapy, of whom 11 received preoperative neoadjuvant chemotherapy. Postoperative nasal bleeding was observed in 2 patients. The follow-up ranged from 8 to 124 months (median, 42.3 months). The 1-year and 5-year overall survival were 96.2% and 84.8%, respectively. The 1-year and 5-year disease-free survival were 76.9% each. The analysis of the postoperative Sino-Nasal Outcome Test scores showed significant improvement in certain psychological and sleep-associated domains, compared with the preoperative scores. CONCLUSIONS Our results showed that pure EEA followed by radiotherapy offered excellent outcomes in the management of selected patients with locally advanced ONB. The postoperative QOL was significantly improved. More research is required on neoadjuvant chemotherapy to establish its role.

Abstract
Background: Esthesioneuroblastoma (ENB) is a rare sinonasal malignancy, lacking a unified staging system and treatment. Management at a single center was retrospectively evaluated to inform future treatment options and prognostic factors. Methods: Clinical data of 64 consecutive ENB patients, including prognostic factors and treatment methods, were reviewed retrospectively. Data were collected to calculate overall survival (OS) and progression free survival (PFS). Results: The majority of tumors 84.4% were within Kadish C stage, 79.7% were within T3 or T4, and 64.0% were within Hyams grade III or IV. A total of 50 (78.1%) patients received surgery and combined radiotherapy with or without chemotherapy, 10 (15.6%) received surgery with or without chemotherapy alone, and 4 (6.3%) received radiotherapy with or without chemotherapy alone. The majority of patients (79.7%) underwent endoscopic resection (endoscopic and endoscopically assisted). Surgery combined with radiotherapy with or without chemotherapy resulted in significantly better OS (84.4 vs. 50.6%, 84.4 vs. 37.5%) compared to surgery alone and radiotherapy alone (P = 0.0064). Endoscopic surgery group (endoscopic and endoscopically assisted) resulted in significantly better 5-year PFS (61.7 vs. 22.2%) compared to the open surgery group (P < 0.001). Although endoscopic surgery group was not a statistically significant predictor of 5-year OS (P = 0.54), the 5-year OS was 79.3% for the endoscopic surgery group and 76.2% for the open surgery group. A Cox regression analysis identified intracranial extension and surgery combined with radiotherapy as independent factors affecting 5-year OS while cervical lymph node metastasis and Hyams grade IV as independent factors affecting 5-year PFS. Conclusion: Our findings suggest that surgery combined with radiotherapy is the best treatment approach for ENB. For advanced tumors, endoscopic surgery is an effective treatment, and its survival rate is equal to or better than open surgery.

Abstract
BACKGROUND For olfactory neuroblastoma (ONB), the combination of surgical tumor resection and radiation therapy (RT) has been considered the "gold standard" in treatment protocols intended to cure. OBJECTIVE To summarize evidence on the treatment of ONB using surgery alone. METHODS A retrospective institutional case series, a systematic review of the literature, and an individual patient data (IPD) meta-analysis on only surgically treated ONB patients. RESULTS At our institution, a total of 10 patients were treated through surgery alone and remained alive and free of disease at last follow-up. The IPD meta-analysis on 128 patients revealed a disease-free survival (DFS) and overall survival (OS) of 67.7% and 75.4% at 5 years and 57.1% and 71.9% at 10 years, respectively. Univariate analysis showed that Kadish stage C/D and Hyams grading III//IV significantly affected OS (P = 0.000 and P = 0.000) and DFS (P = 0.000 and P = 0.002). For low-risk patients, the DFS was 80.6% at 5 years and 67.8% at 10 years, respectively. CONCLUSIONS Surgery alone is an equivalent alternative to combined treatment in carefully selected low-risk ONB patients with better outcome measures than previously reported.

Cancer Manag Res 2020; 12:8355-8362. [PMID: 32982429 PMCID: PMC7490047 DOI: 10.2147/cmar.s259921] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/25/2020] [Accepted: 08/04/2020] [Indexed: 11/23/2022] Open
Abstract
Purpose Esthesioneuroblastoma (ENB) is a type of rare malignant neoplasm of the sinonasal cavity. Optimal treatment for ENB is still controversial. A retrospective study was conducted to identify the clinical outcome and optimal treatment for ENB in the era of intensity-modulated radiation therapy (IMRT). Patients and Methods Between December 2006 and August 2018, 37 patients with ENB without distant metastasis who underwent neoadjuvant chemotherapy followed by chemoradiotherapy (C+RC) or surgery followed by radiotherapy or chemoradiotherapy (S+R/RC) were retrospectively reviewed at our center. Results The median follow-up period was 63.7 months (range, 13.2-111.5 months). Five-year overall survival (OS), progression-free survival (PFS), locoregional relapse-free survival (LRFS), and distant metastasis-free survival (DMFS) were similar between treatment arms (P values > 0.05). With a multivariate analysis, a Karnofsky Performance Status (KPS) of ≤80 was a prognostic factor for poor five-year OS. A KPS of ≤80 and Kadish class C-D tumors were prognostic factors for poor PFS. A KPS of ≤80 was a prognostic factor for poor LRFS. When KPS was ≤80 and tumors were Kadish class C-D, T3-4 and N1 were prognostic factors for poor DMFS. Subgroup analyses also demonstrated that the two treatment arms exhibited similar trends for OS, PFS, LRFS, and DMFS, excluding patients with N1 or Kadish class A-B tumors (P values > 0.05). Conclusion In the era of IMRT, S+R/RC failed to improve the outcomes of patients with ENB. C+RC may be a feasible treatment option for patients with ENB.

Abstract
The esthesioneuroblastoma (ENB) is characterized as a rare malignant sinonasal tumor of neuroectodermal origin. Its starting point is the olfactory epithelium located in the upper part of the nasal cavities. Different nomenclatures have been proposed, but the most common are "esthesioneuroblastoma" and "olfactory neuroblastoma". ENBs have a bimodal distribution and mainly occur in teenagers, young adults and people aged 50-60. It is a very rare tumor in pediatrics since only around 100 cases have been reported so far. Within ENBs, we can distinguish tumors with different biological behavior ranging from localized forms with slow evolution to aggressive and metastatic forms at onset. In addition, precisely diagnosing undifferentiated tumors and distinguishing them from other etiologies of sinonasal tumors are sometime difficult. Added to its very low incidence, these characteristics make the study of ENB complicated. The standard treatment currently includes broad surgery followed by radiation therapy in localized resectable tumors. Neoadjuvant chemotherapy is indicated in large unresectable tumors and in metastatic forms. However, in certain indications, such as high-grade operable tumors, the role of perioperative chemotherapy remains to be defined. The objective of this analysis is to detail current knowledge regarding ENBs' epidemiological, biological, clinical and radiological characteristics as well as how to manage ENB in young patients.

Abstract
Background Consensus in timing of radiotherapy is yet to be established in esthesioneuroblastoma (ENB). Objective This study was aimed to investigate if planned adjuvant radiotherapy improves tumor control after complete margin negative resection of low Hyams' grade (1 or 2) ENB. Methods A retrospective review of patients with pathologically confirmed negative margin resection of Kadish's stage B or C and Hyams' grade 1 and 2 ENBs was conducted. Seventeen patients meeting the criteria were divided into the following two groups for cohort study: (1) those who underwent planned immediate postoperative adjuvant radiotherapy (IR group) and (2) those who did not (delayed radiotherapy [DR] group). Results The IR group included nine patients (Kadish's stage B in one and stage C in eight; Hyams' grade 1 in two and grade 2 in seven). Mean follow-up was 140.8 months. Seven patients (78%) had disease progression (DP) at a median of 88 months (four with cervical lymph node metastasis [CLNM], one with distant metastasis, and two with both local recurrence and CLNM). One patient experienced frontal lobe abscess. The DR group included eight patients (Kadish's stage B in six and stage C in two; all Hyams' grade 2). Mean follow-up was 123.3 months. Four (50%) patients who developed DP (all local recurrence) were salvaged with surgery and adjuvant radiotherapy at a median of 37.5 months. There was no statistically significant difference in DP rate ( p = 0.23), time to DP ( p = 0.26), or the local tumor control rate ( p = 0.23). Conclusion In our limited cohort, immediate postoperative radiotherapy did not demonstrate superiority in tumor control, although risk of radiotherapy toxicity appears low.

Abstract
BACKGROUND In this study, we evaluate our experience and the outcomes of patients with sinonasal cancer treated with endoscopic resection. METHODS Retrospective review of patients with sinonasal cancer who had endoscopic resection was conducted. The outcomes of interest included survival outcomes and surgical complications. RESULTS Overall, 239 patients were included. Median follow up time was 46.6 months. Of the 239 patients, 167 (70%) had a pure endonasal endoscopic approach, while 72 (30%) had an endoscopic-assisted approach. Postoperative cerebrospinal fluid (CSF) leakage occurred in 14 patients (5.9%). Negative margins were achieved in 209 patients (87.4%). There was no significant difference in the margin status between the pure endoscopic and endoscopic-assisted group (P = .682). There was no significant difference in the survival outcomes between both the groups. CONCLUSION Our data suggest that in properly selected patients, endoscopic approaches have acceptable morbidity with low complication rates and can provide an oncologically sound alterative to open approaches.

Abstract
OBJECTIVE Olfactory neuroblastoma (ONB) is a rare malignant neoplasm of the sinonasal cavity. Surgery has been and remains a mainstay of treatment for patients with this tumor. Open craniofacial resections have been the treatment of choice for many decades. More recently, experience has been growing with endoscopic approaches in the management of patients with ONB. The object of this study is to report the authors' experience over the past 11 years with ONB patients treated with purely endonasal endoscopic techniques. METHODS The authors performed a retrospective chart review of 20 consecutive patients with ONB who underwent a completely endonasal endoscopic approach for an oncological tumor resection at their institution between January 2006 and January 2017. Patient demographics, tumor stage, pathological grade, frozen section analysis, permanent margin assessment, perioperative complications, postoperative therapy, length of follow-up, and outcomes at last follow-up were collected and analyzed. RESULTS Eighteen patients presented with newly diagnosed disease, with a modified Kadish stage of A in 2 cases, B in 3, C in 11, and D in 2. Two patients presented with recurrent tumors. An average of 25.3 specimens per patient were examined by frozen section analysis. Although analysis of intraoperative frozen section margins was negative in all but 1 case, microscopic foci of tumor were found in 7 cases (35%) on permanent histopathological analysis. Perioperative complications occurred in 7 patients (35%) including 1 patient who developed a cerebrospinal fluid leak; there were no episodes of meningitis. All but 1 patient received postoperative radiotherapy, and 5 patients received postoperative chemotherapy. With a mean follow-up of over 5 years, 19 patients were alive and 1 patient died from an unrelated cause. There were 2 cases of tumor recurrence. The 5-year overall, disease-specific, and recurrence-free survival rates were 92.9%, 100%, and 92.9%, respectively. CONCLUSIONS The current results provide additional evidence for the continued use of endoscopic procedures in the management of this malignancy.

Abstract
INTRODUCTION Many controversies exist in the diagnosis and management of this aggressively malignant condition, mainly because of limited literature and lack of randomized control trials, resulting in nonstandardized treatment methods. We performed a comprehensive review of the literature to identify management approach and treatment options for esthesioneuroblastoma. METHODS An extensive review of the published literature was conducted in PubMed, OVID Medline, and EMBASE journals for studies of esthesioneuroblastoma. Terms for search included esthesioneuroblastoma (ENB) and olfactory neuroblastoma (ONB). No date restrictions were used. RESULTS The search yielded 3876 related articles. Cross-checking of articles led to exclusion of duplicate articles. The remaining 1170 articles were screened for their full text and English language availability. Of 609 full-text articles available, animal studies, irrelevant articles, and studies with mixed/confusing data were excluded. We finalized 149 articles pertaining to the topic, including 119 original research articles, 3 book chapters, 11 reviews, 9 case reports, and 7 case series. CONCLUSIONS Surgical resection followed by radiotherapy is the standard for treatment for higher-grade lesions. The endoscopic endonasal approach is gaining further recognition with more favorable outcomes and better survival than for open surgery. Postoperative radiotherapy is associated with the highest overall survival and shows benefit for patients with higher-stage disease and those who receive chemotherapy. Recurrence rates after treatment vary drastically in the literature and, therefore, prolonged follow-up with repeated imaging is recommended. Lifelong surveillance is recommended because of late recurrences associated with this tumor.

Abstract
During the last two decades evolution of the endoscopic endonasal approaches (EEA) has offered the option of minimally invasive techniques in the management of esthesioneuroblastomas (ENB), either as endoscope assisted cranial resection or as pure endoscopic procedures. This study presents the use of pure EEA in the management of ENB in our center, along with a literature review. We retrospectively reviewed the clinical, radiology and pathology records of patients with ENB treated during the period July 2006 to January 2016. During the above period, ten patients with ENB were treated using pure EEA. The mean age was 47.5 years. The gender distribution was: eight males, two females. The most common presenting symptoms were nasal obstruction and discharge or epistaxis (8/10). The mean duration of symptoms was 1.5 years. All patients had preoperative confirmation of ENB by biopsy. Five patients received neoadjuvant radiation and four underwent postoperative radiation. One patient did not receive any radiotherapy and no patient received chemotherapy. Gross total resection was achieved in all patients and intraoperative microscopically negative surgical margins achieved in 9/10 (90%). No major intraoperative complications occurred. The most common postoperative complication was nasal infection. Cerebrospinal fluid leak was noted in one patient. During the follow-up period of 6-120 months (mean 74.8) two cases of neck lymph node recurrence were observed. No deaths due to the disease occurred during the follow-up period. Pure EEA offer excellent results in the management of ENB. Neoadjuvant radiation treatment is promising although more studies need to establish its role.

Abstract
PURPOSE OF REVIEW To provide a comprehensive review of the literature focusing on the recent advances in the diagnosis and management of olfactory neuroblastoma. RECENT FINDINGS Multimodality treatment is usually recommended for the majority of ONB cases. Recent advances in surgical approaches include the evolving role of endonasal endoscopic surgical resection and reconstruction. The introduction of new conformal radiation techniques has improved the outcomes and reduced treatment-related toxicity to important structures such as the eye and the brain. The role of neoadjuvant and adjuvant chemotherapy is yet to be defined. In the last two decades, there have been advances in surgical techniques with endoscopic approaches, either alone or in combination with craniotomy, gradually replacing the open traditional approaches. Prolonged surveillance is recommended for ONB due to late recurrences associated with that tumor. The role of chemotherapy and elective neck irradiation is still controversial and needs more studies to investigate their optimal role.

[PMID: 29421455 DOI: 10.1016/j.wneu.2018.01.142] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/10/2016] [Revised: 01/17/2018] [Accepted: 01/18/2018] [Indexed: 10/18/2022]
Abstract
BACKGROUND Reconstruction of large anterior skull base (ASB) defects after an endoscopic endonasal transcribriform approach (EEA-TC) remains a challenge despite the advent of the vascularized pedicled nasoseptal flap (PNSF). OBJECTIVE We describe a relaxing PNSF slit incision that extends the anterior and posterior reach of the PNSF to maximize tensionless flap coverage of transcribriform ASB defects. METHODS A retrospective chart review was conducted on 20 consecutive patients who underwent endoscopic endonasal transcribriform approach and subsequent PNSF reconstruction with a relaxing slit incision. At the time of endoscopic ASB reconstruction, the PNSF is rotated into position so that the anterior margin of the flap is situated at the posterior table of the frontal sinus. A relaxing slit incision is made across the sphenoidal segment of the PNSF, which is the segment of flap that bridges across the sphenoid sinus once the flap is rotated into position. The anterior reach of the flap is increased to adequately cover the posterior table of the frontal sinus, and the redundant sphenoidal flap is rotated posteriorly to make contact to the bony planum sphenoidale. RESULTS No patients developed postoperative cerebrospinal fluid leaks (0%). The ASB repair was monitored via postoperative outpatient nasal endoscopy at various time points, which demonstrated excellent mucosalization of the ASB with a mean follow-up of 19.2 months (range: 4.1-36.2 months). CONCLUSIONS Our simple relaxing slit incision in the sphenoidal portion of the PNSF allows for maximal tensionless coverage of extensive transcribriform defects by increasing the anterior and posterior reach of the flap.

Abstract
Objectives Evaluation of the changing trends in esthesioneuroblastoma in an Irish context and review of management options nationally to clarify the best current therapeutic approach by comparing with international research on this uncommon malignancy. Design Retrospective review. Setting Tertiary referral center. Participants All patients presenting with esthesioneuroblastoma in Beaumont hospital or on the National Cancer Registry of Ireland between 1994 and 2013. Main Outcome Measures Recurrence-free and overall survival. Results During the study period, 32 cases of esthesioneuroblastoma were diagnosed (0.4 per million per year). Average age at diagnosis was 57 years; however, two cases were under 20. The majority (62.5%) were male. Patients predominantly presented with epistaxis or nasal congestion (73%), while two cases were identified incidentally on radiological investigations. Twenty-seven cases underwent primary surgical management (two post neo-adjuvant treatment) with seventeen requiring bifrontal craniotomy. Twenty-four of these received postoperative radiation therapy. Overall, 5-year survival was 65%. Kadish A/B patients exhibited 100% 5-year disease-specific survival versus 54% in Kadish C/D ( p = 0.011). Hyams grade I/II patients exhibited 75% 5-year disease-specific survival versus 63% in Hyams grade III/IV ( p = 0.005). Patients treated endoscopically exhibited 100% 5-year disease-specific survival versus 51% in those treated via an open approach ( p = 0.102). Conclusions Many controversies exist in the diagnosis and management of this condition. Despite this, results from Irish data are mostly concordant with the international literature. The rising incidence of this disease may represent improved pathological recognition. An increasing number of esthesioneuroblastoma cases are being successfully treated via endoscopic surgery.

Abstract
INTRODUCTION AND OBJECTIVES Olfactory neuroblastoma (ONB) is a rare entity that constitutes less than 5% of nasosinusal malignancies. Mainstream treatment consists in surgical resection+/-adjuvant radiotherapy. By exposing results observed with apparition of new therapeutic options as neoadjuvant chemotherapy, the objective is to evaluate a series and a review of the current literature. METHODS A retrospective review was conducted including patients diagnosed and followed-up for ONB from 2008 to 2015 in our institution. RESULTS 9 patients were included. Mean follow-up of 52.5 months (range 10-107). Kadish stage: A, 1 patient (11.1%) treated with endoscopic surgery; B, 2 patients (22.2%) treated with endoscopic surgery (one of them received adjuvant radiotherapy); C, 6 patients (66.7%), 4 patients presented intracranial extension and were treated with neoadjuvant chemotherapy followed by surgery and radiotherapy. The other 2 patients presented isolated orbital extension, treated with radical surgery (endoscopic or craniofacial resection) plus radiotherapy. The 5-year disease free and overall survival observed was 88.9%. CONCLUSION Neoadjuvant chemotherapy could be an effective treatment for tumor reduction, improving surgical resection and reducing its complications.

Abstract
OBJECTIVE The aim of the present study was to illustrate the safety and utility of the endoscopic endonasal approach (EEA) for the treatment of esthesioneuroblastomas (ENB). METHODS We retrospectively reviewed patients with a diagnosis of ENB between March 2008 and February 2016 at 10 tertiary referral hospitals in Japan, and assessed demographic data, stage of disease, surgical approach, outcomes and postoperative complications. RESULTS A total of 22 patients (10 males and 12 females; mean age at presentation, 49.0 years) underwent endoscopic endonasal resection of newly diagnosed ENBs. Dulguerov staging at presentation was T1, 6 patients; T2, 9 patients; T3, 5 patients; and T4, 2 patients. As surgical procedures, unilateral resection via EEA was performed in 12 patients aiming preservation of the contralateral olfactory system, and bilateral resection via EEA was done in 10 patients. Post-operative radiotherapy was done in 20 patients. Pathological margin studies revealed margin-free resections in 21 patients (95.5%). The mean period of follow-up was 44 months. Local recurrence was observed in one T2 patient 12 months after bilateral resection. All patients were alive at the last follow-up, and 21 patients showed no evidence of disease. No post-operative complications including bleeding, CSF leak and meningitis were identified. Preservation of olfactory function was achieved in 11 patients (91.7%). CONCLUSION The results of the present study indicate the safety and utility of multilayer resection using EEA for treatment of ENBs.

Abstract
Olfactory neuroblastoma (ONB) is a potentially curable disease, despite being an aggressive malignancy with a poor natural history. Our goal was to evaluate management outcomes for patients with ONB treated at our institution. Our prospective database for brain tumors and the pathology registry of head and neck cancers at Oslo University Hospital were searched to identify all patients treated for ONB between 1998 and 2016. Variables extracted from these databases, supplemented by retrospective chart reviews, underwent thorough analysis. All cases were formally re-examined by a dedicated head and neck pathologist. Twenty patients were identified. Follow-up was 100%. Mean follow-up was 81.5 months for the entire cohort and 120.3 months for patients with no evidence of disease. Fourteen patients underwent treatment of choice including craniofacial resection (CFR) with or without radiotherapy (XRT). Six patients could only receive less extensive treatment; three patients underwent lateral rhinotomy (LR) with or without XRT after being deemed medically unsuitable for CFR, while another three patients received only supportive, non-surgical treatment (due to positive lymph node status in two and to extensive tumor size in one case). Overall and disease-specific survival rates were 100% after 10 years of follow-up when negative surgical margins were achieved by CFR. Positive margins were associated with poorer outcome with no patients surviving longer than 44 months. Long-term survival was also achieved in two cases among patients not eligible for CFR: one case after radical LR and one case after radio-chemotherapy. Advanced disease at presentation (tumor size ≥40 mm, Kadish grades C and D, or TNM IVa and IVb) and positive surgical margins were correlated to significantly dismal survival. Our study suggests that CFR with or without adjuvant XRT is safe and leads to excellent long-time overall and disease-specific survival. Negative surgical margins, tumor size <40 mm, Kadish stage A/B, and TNM stages I-III are independent prognostic predictors of outcome.

Abstract
INTRODUCTION In esthesioneuroblastoma, greater disease extent and Kadish staging correlate with greater recurrence, complications, and mortality. These advanced stage malignancies require extensive resections and aggressive adjuvant therapy. This increases the risk of complications such as cerebrospinal fluid leak, neurologic deficits, and osteomyelitis. We present our case series and then analyze the literature to ascertain whether advanced stage tumors corresponds to greater rates of complications. METHODS A retrospective review of consecutive patients with histologically-proven esthesioneuroblastoma who were aggressively managed at our institution was performed. This was followed by an extensive literature search of published original data, in large series from 2006-2016, where both surgery and adjuvant therapy were used for the treatment of esthesioneuroblastoma. RESULTS Single institution review revealed eight patients with esthesioneuroblastoma, half with advanced Kadish staging. All Kadish A patients ( Kadish A: confined to nasal cavity) underwent endoscopic approaches alone, while Kadish C patients (Kadish C: extends beyond nasal cavity and paranasal sinuses) and D patients (Kadish D: lymph node or distant metastases) underwent craniofacial approaches, while all patients received post-operative adjuvant therapies. Complications such as cerebrospinal fluid (CSF) leak, seizures, meningitis, and abscess only occurred in high Kadish stage patients. Literature review demonstrated a higher proportion of advanced Kadish stage cases correlated with increasing rates of pneumocephalus, infection, and recurrence. A higher proportion of Kadish C and D tumors was inversely correlated with CSF leak rate and overall survival. DISCUSSION Advanced stage tumors are often associated with a higher incidence of adverse events up to 33%, both due to disease burden and treatment effect. There is increasing use of endoscopy and neoadjuvant therapy, which have the potential to decrease complication rates. CONCLUSION Advanced Kadish stage esthesioneuroblastoma necessitates meticulous surgical resection and aggressive adjuvant therapies, together, these increase the likelihood of adverse events, including CSF leak, neurologic deficits, and infections, and may represent the real morbidity cost of radically treating these tumors to achieve an improvement in overall survival. In selected patients, less-invasive approaches or neo-adjuvant therapies can be used without compromising on a curative resection.

Abstract
Introduction Advanced Kadish stage esthesioneuroblastoma requires more extensive resections and aggressive adjuvant therapy to obtain adequate disease-free control, which can lead to higher complication rates. We describe the case of a patient with Kadish D esthesioneuroblastoma who underwent multiple surgeries for infectious, neurologic, and wound complications, highlighting potential preventative and salvage techniques. Case Presentation A 61-year-old man who presented with a large left-sided esthesioneuroblastoma, extending into the orbit, frontal lobe, and parapharyngeal nodes. He underwent margin-free endoscopic-assisted craniofacial resection with adjuvant craniofacial and cervical radiotherapy and concomitant chemotherapy. He then returned with breakdown of his skull base reconstruction and subsequent frontal infections and ultimately received 10 surgical procedures with surgeries for infection-related issues including craniectomy and abscess evacuation. He also had surgeries for skull base reconstruction and CSF leak, repaired with vascularized and free autologous grafts and flaps, synthetic tissues, and CSF diversion. Discussion Extensive, high Kadish stage tumors necessitate radical surgical resection, radiation, and chemotherapy, which can lead to complications. Ultimately, there are several options available to surgeons, and although precautions should be taken whenever possible, risk of wound breakdown, leak, or infection should not preclude radical surgical resection and aggressive adjuvant therapies in the treatment of esthesioneuroblastoma.

Abstract
BACKGROUND We describe a rare case of a sphenoid sinus myxoma that was resected via an endoscopic endonasal skull base approach. We review the literature regarding these rare tumors of the paranasal sinuses. CASE DESCRIPTION A 72-year-old woman was diagnosed with an incidental sphenoid sinus tumor and left sphenoid wing meningioma during a workup for left-sided proptosis and diplopia. Biopsies of the sphenoid wing and sphenoid sinus tumors were obtained. After undergoing surgical resection of the meningioma, the patient then underwent definitive resection of the sphenoid sinus myxoma via endoscopic endonasal skull base approach. Postoperative imaging demonstrated a gross total resection. The patient suffered postoperative thromboembolic complications due to underlying hypercoagulable state but made a complete recovery and returned to her neurologic baseline. There has been no evidence of recurrent myxoma in the sphenoid sinus 24 months after surgery. DISCUSSION Myxomas are benign tumors derived from primitive mesenchyme. Myxomas very rarely present in the paranasal or skull base location. Complete surgical resection is the primary treatment for these tumors. The endoscopic endonasal approach is an effective technique for resecting various benign and more aggressive extradural skull base tumors. CONCLUSIONS Myxomas of the sphenoid sinus are rare. The endoscopic endonasal skull base approach is an effective and minimal access technique for resection of this rare tumor of the sphenoid sinus.

Abstract
Objectives Sinonasal cancers with neuroendocrine features share similar clinical, radiological, and histopathological features; however, these tumors often exhibit varying degrees of aggressive behavior presenting significant treatment challenges. The objective of this study was to report our experience with these rare malignancies and to present a review of current literature. Methods Following institutional review board approval, the records of all patients with biopsy-proven sinonasal malignancies over a 5-year period were reviewed. Results The study included 14 patients with olfactory neuroblastomas (ONBs), 7 patients with sinonasal undifferentiated carcinomas (SNUC), and 2 patients with sinonasal neuroendocrine carcinomas (SNEC). Histopathologic markers aided in final diagnosis, but showed variable specificity. In patients with sufficient follow-up, the 2-year disease-free survival rate was 81% (9/11) for ONB and 75% (3/4) for SNUC. Three patients developed a regional or distant recurrence (two with ONBs and one with SNUC). Two patients, one with SNEC and one with ONB, succumbed to brain radionecrosis related to proton radiation therapy. Conclusions Overlapping clinical and histopathological features in poorly differentiated sinonasal cancers with neuroendocrine features continue to present a diagnostic challenge. Individualized assessment and treatment strategies can improve the accuracy of the initial assessment and the treatment outcomes.

Abstract
PURPOSE OF REVIEW This article provides a contemporary review of the management of esthesioneuroblastoma (ENB) within the context of recent surgical advancements, while highlighting the ongoing limitations and controversies surrounding this uncommon pathologic entity. RECENT FINDINGS Surgical management of ENB is continuously evolving with contemporary endoscopic approaches complementing or in many cases replacing open approaches. SUMMARY Complete surgical resection remains the mainstay definitive therapy for ENB. Aggressive, combined modality therapy appears to be justified in patients at greatest risk of developing recurrence based on advanced tumor stage and high pathologic grade. ENB requires prolonged surveillance following treatment given its tendency for late recurrence.

Abstract
Esthesioneuroblastoma is a rare malignant tumor of sinonasal origin. These tumors typically present with unilateral nasal obstruction and epistaxis, and diagnosis is confirmed on biopsy. Over the past 15 years, significant advances have been made in endoscopic technology and techniques that have made this tumor amenable to expanded endonasal resection. There is growing evidence supporting the feasibility of safe and effective resection of esthesioneuroblastoma via an expanded endonasal approach. This article outlines a technique for endoscopic resection of esthesioneuroblastoma and reviews the current literature on esthesioneuroblastoma with emphasis on outcomes after endoscopic resection of these malignant tumors.

Recurrent Olfactory Neuroblastoma in Remote Leptomeninges, Mimicking Intracranial Meningioma. World Neurosurg 2016; 96:612.e9-612.e14.

Abstract
BACKGROUND Olfactory neuroblastoma (ONB) is an uncommon neoplasm that arises from olfactory epithelium in the nasal cavity near the cribriform plate. Although local recurrence or direct extension along olfactory epithelium and metastasis to the central nervous system has been reported, remote leptomeningeal metastasis is quite rare. In our report of a leptomeningeal metastasis of ONB without recurrence of primary site, we discuss the possible pathogenesis of this rare phenomenon with a review of the literature. CASE DESCRIPTION A 56-year-old woman was admitted with epistaxis. Magnetic resonance imaging revealed a mass in the right cribriform plate and ethmoid sinus with intracranial extension. She was primarily treated with craniofacial resection followed by radiotherapy. Gross total resection was achieved, but annual follow-up magnetic resonance imaging showed a new enhancing mass in the left parietal meninges mimicking meningioma without local recurrence at 5 years after the first operation. A second operation was performed, and pathologic examination confirmed the lesion as metastatic olfactory neuroblastoma. CONCLUSIONS ONB is a locally aggressive tumor, but it also potentially spreads to remote leptomeninges via blood or cerebrospinal fluid. Therefore, careful evaluation is needed not to misdiagnose a meningioma and delay the treatment. Moreover, understanding the route of remote leptomeningeal metastasis and en-bloc resection of tumor at first operation might reduce leptomeningeal metastasis, irrespective of surgical corridors.

Abstract
BACKGROUND Esthesioneuroblastoma (ENB) is a rare, poorly characterized, intranasal cancer arising from olfactory neuroepithelium. METHODS This case report reviews the underlying pathophysiology, clinical presentation, and diagnosis of primary ENB and parotid metastases. RESULTS We present the case of a 43-year-old man who was referred to our practice with radiographically and biopsy confirmed ENB. After neoadjuvant chemotherapy, radiation, and open surgical resection, he returned to the clinic 30 months postoperatively with a right parotid mass, which was found to be a recurrence of his primary cancer. A parotidectomy was performed; however, he returned 10 months later with a new left parotid mass. Subsequent imaging and biopsy confirmed recurrence of ENB and a second parotidectomy was performed. CONCLUSION This case illustrates that delayed metastases in the setting of ENB are not limited to the cervical lymph nodes and, in rare instances, may involve the parotid glands. Surveillance should include the parotid lymph node basin with a high clinical index of suspicion in the setting of parotid lymphadenopathy after primary surgical therapy. © 2016 Wiley Periodicals, Inc.

Abstract
BACKGROUND Endoscopic skull base surgery is becoming more popular as an approach to the anterior skull base for tumors and cerebrospinal fluid (CSF) fistulae. It offers the advantages of better cosmesis and improved quality of life after surgery. We reviewed the complication rates reported in the literature. METHODS A literature search was performed in the electronic database Ovid MEDLINE (1950 to August 25, 2015) with the search item "([Anterior] AND Skull base surgery) AND endoscopic." RESULTS We identified 82 relevant studies that included 7460 cases. An average overall complication rate of 17.1% (range 0%-68.0%) and a mortality rate of 0.4% (0%-10.0%) were demonstrated in a total of 82 studies that included 7460 cases. The average CSF leak rate for all studies was 8.9% (0%-40.0%) with meningiomas and clival lesions having the greatest CSF leak rates. The most frequent benign pathology encountered was pituitary adenomas (n = 3720, 49.8% of all cases) and the most frequent malignant tumor was esthesioneuroblastoma (n = 120, 1.6% of all cases). Studies that included only CSF fistula repairs had a lower average total complication rate (12.9%) but a greater rate of meningitis compared with studies that reported mixed pathology (2.4% vs. 1.3%). A trend towards a lower total complication rate with increasing study size was observed. CONCLUSIONS The endoscopic approach is an increasingly accepted technique for anterior skull base tumor surgery and is associated with acceptable complication rates. Increasing experience with this technique can decrease rates of complications.

Abstract
OBJECTIVE Anterior craniofacial resection has served as the traditional surgical treatment of olfactory neuroblastoma (ON). With the development of extended endonasal approaches, the opportunity exists for using minimal access techniques for management of select tumors. This study assesses the impact of endoscopic resection on ON and patient outcomes and quality of life. METHODS A retrospective review identified 10 patients with ON (3 women, 7 men; mean age 49.1 years) who underwent endoscopic resection during the period 2010-2013. Modified Kadish staging divided the cohort into 3 stage B patients (30%), 5 stage C patients (50%), and 2 stage D patients (20%). Outcome measures included extent of resection, complications, recurrence, and preoperative and postoperative Sino-Nasal Outcome Test-20 scores. RESULTS Gross total resection was achieved in all patients, with negative margins in 9 patients. One patient had negative frozen section pathology but was noted to have a positive posterior dural margin on final pathology. There was a 20% complication rate (pneumocephalus, ethmoid meningoencephalocele). Neoadjuvant chemotherapy and radiation were performed in 2 patients (Kadish stage C and D). Adjuvant chemotherapy and radiation were performed in 5 patients (4 Kadish stage C and 1 stage D). Postoperative radiation alone was administered in 3 patients (Kadish stage B). Analysis of postoperative Sino-Nasal Outcome Test-20 scores demonstrated no significant change relative to preoperative Sino-Nasal Outcome Test-20 scores. At the most recent follow-up examination, there was no evidence of recurrent disease in patients who underwent endoscopic resection. One patient (Kadish stage D) died during the follow-up period. Mean follow-up duration was 21.1 months. CONCLUSIONS This series adds to the growing body of literature that suggests equivalent or improved outcomes of purely endonasal resection for select patients. Given the advanced Kadish stage of most of our patients, longer follow-up is required to determine the full applicability of purely endoscopic approaches to the treatment of ON.

Abstract
Adenoid cystic carcinoma (ACC) is a rare malignant tumor that might occur in nasal cavity and paranasal sinuses. It is characteristic for poor prognosis, especially the solid histopathological subtype of the tumor. ACC might spread along nerves and fascias and it is usually diagnosed at advanced stage. Computed tomography and magnetic resonance imaging together with fine-needle biopsy are the gold standards in the diagnostic procedure of the cancer. Surgery with adjuvant therapy are the most common methods of treatment. Among the surgical approaches, the functional endonasal sinus surgery seems to be the most appropriate and favorable way of treatment. In the study, the authors present a case of a 62-year-old patient with T4aN0M0 ACC tumor treated endoscopically at the Department of Laryngology and ENT Oncology, WSS No. 5 in Sosnowiec. The authors indicate the usefulness of FESS procedure in the treatment of malignancies of nasal cavity and paranasal sinuses. They also review the recent publications on endonasal versus open approach in similar cases. In conclusions, the authors favor endonasal approach as a mini-invasive method of surgical treatment of ACC of paranasal sinuses that results in satisfactory oncological outcome and high quality of patient's life.

Abstract
BACKGROUND Endoscopic orbital surgery represents the next frontier in endonasal surgery. The current literature is largely composed of small, heterogeneous, case series with little consensus regarding optimal techniques. The purpose of this study was to combine the experience of multiple international centers to create a composite of the global experience on the endoscopic management of a single type of tumor, the orbital cavernous hemangioma (OCH). METHODS This was a retrospective study of techniques for endoscopic OCH resection from 6 centers on 3 continents. Only primary data from strictly endoscopic resection of OCHs were included. Responses were analyzed to qualitatively identify points of both consensus and variability among the different groups. RESULTS Data for a total of 23 patients, 10 (43.5%) male and 13 (56.5%) female were collected. The majority of lesions were intraconal (60.9%). The mean ± standard deviation (SD) surgical time was 150.7 ± 75.0 minutes with a mean blood loss of 82.7 ± 49.6 mL. Binarial approaches (26.1%) were used exclusively in the setting of intraconal lesions, which were associated with a higher rate of incomplete resection (31.3%), postoperative diplopia (25.0%), and the need for reconstruction (37.5%) than extraconal lesions. Orthotropia and symmetric orbital appearance were achieved in 60.9% and 78.3% of cases, respectively. CONCLUSION Extraconal lesions were managed similarly; however, greater variability was evident for intraconal lesions. These included the laterality and number of hands in the approach, methods of medial rectus retraction, and the need for reconstruction. The increased technical complexity and disparity of techniques in addressing intraconal OCHs suggests that continued research into the optimal management of this subclass of lesions is of significant priority.

Abstract
BACKGROUND Endoscopic approaches have been adopted as an alternative to craniofacial resection in the surgical management of olfactory neuroblastoma. METHODS We conducted a systematic review and meta-analysis using MEDLINE, EMBASE, Cochrane, and CINAHL (2000-2014) to compare outcomes for open versus endoscopic approaches. RESULTS Thirty-six studies containing 609 patients were included. Meta-analysis of (a) all patients, (b) Kadish C/D only, and (c) Hyams III/IV only, failed to show a difference in locoregional control and metastasis-free survival between approaches. However, endoscopic approaches were associated with improved overall survival (OS) for all 3 groups (p = .001, .04, and .001, respectively), and higher disease-specific survival (DSS) for all patients (p = .004) and Hyams III/IV only (p = .002). CONCLUSION The current study suggests that endoscopic approaches have comparable control rates to open approaches for olfactory neuroblastoma. © 2015 Wiley Periodicals, Inc.

Abstract
OBJECTIVE Esthesioneuroblastoma (ENB) is an uncommon malignant tumor. During the past decade, endoscopic approaches have been gradually applied in treating skull base tumors. However, the experience in using this approach to treat ENB is still limited. Kadish staging and Dulguerov staging are common methods used for ENB staging, but it remains unclear as to which method is better. In this study, we reviewed our experiences with endoscopic surgeries for ENB and analyzed the prognostic roles of the two staging methods. METHODS A total of 24 patients with ENB treated with only endoscopic endonasal surgery between January 2001 and March 2012 were included. Overall survival (OS) and disease-free survival (DFS) were analyzed using the Kaplan-Meier method and early and advanced stages were compared using the log-rank test. The prognostic roles of the two staging methods were also analyzed. RESULTS Amongst the 24 patients, 19 patients presented with newly diagnosed ENB, and 5 patients presented with recurrent disease. The three-year OS and DFS rates were 82% and 70.8%, respectively. Four patients (16.6%) died from recurrence of the tumor. Dulguerov staging predicted OS with significant differences (P=0.042), whereas Kadish staging predicted DFS with significant differences (P=0.020) between the early and advanced stages. CONCLUSIONS The present study showed experiences that purely endoscopic endonasal surgery for ENB showed successful survival results with remarkably decreased complications. Dulguerov staging and Kadish staging play different prognostic roles in patients treated with purely endoscopic endonasal resection based on various end points.

Abstract
Introduction Malignant sinonasal tumors comprise less than 1% of all neoplasms. A wide variety of tumors occurring primarily in this site can present with an undifferentiated or poorly differentiated morphology. Among them are esthesioneuroblastomas, sinonasal undifferentiated carcinomas, and neuroendocrine carcinomas. Objectives We will discuss diagnostic strategies, recent advances in immunohistochemistry and molecular diagnosis, and treatment strategies. Data Synthesis These lesions are diagnostically challenging, and up to 30% of sinonasal malignancies referred to the University of Texas MD Anderson Cancer Center are given a different diagnosis on review of pathology. Correct classification is vital, as these tumors are significantly different in biological behavior and response to treatment. The past decade has witnessed advances in diagnosis and therapeutic modalities leading to improvements in survival. However, the optimal treatment for esthesioneuroblastoma, sinonasal undifferentiated carcinoma, and neuroendocrine carcinoma remain debated. We discuss advances in immunohistochemistry and molecular diagnosis, diagnostic strategies, and treatment selection. Conclusions There are significant differences in prognosis and treatment for esthesioneuroblastoma, neuroendocrine carcinoma, and sinonasal undifferentiated carcinoma. Recent advances have the potential to improve oncologic outcomes but further investigation in needed.

Abstract
We describe the clinical findings in two patients with pathologically diagnosed olfactory neuroblastoma (ONB) of the sinonasal area and the surgical methods used for its treatment. Using an endoscopic endonasal approach (EEA) without dura resection, along with radiotherapy, we successfully treated ONB at the Kadish stage A. One of our patients, however, experienced tumor recurrence 24 years after open surgery with radiotherapy that was conducted at another hospital. This patient was no longer eligible for radiotherapy, and the tumor was therefore resected with dura resection using an EEA combined with duraplasty. The dura resection with duraplasty using fascia lata and a pedicled nasal septal flap was minimally invasive. As with surgery without duraplasty, a postoperative computed tomography (CT) examination revealed that EEA with duraplasty led to quick improvement of the postoperative inflammatory response as well as pneumocranium. Here, we investigated whether to modify the method of surgery depending upon the primary site of early-stage ONB. We suggest that, in early-stage ONB, an endoscopic endonasal approach is an effective and less invasive method. It is also advisable to perform dura mater resection of the lesion site despite the absence of obvious intracranial invasions in image findings.

Abstract
Background Esthesioneuroblastoma is an uncommon malignant neoplasm that arises from the olfactory neuroepithelium. In this article we report a case of esthesioneuroblastoma presenting concomitantly with a growth-hormone (GH)-secreting pituitary macroadenoma. Results A 52 year old woman underwent surgery for suspected nasal polyps. Intralesional debulking of an intranasal tumor disclosed a low-grade esthesioneuroblastoma. Magnetic resonance imaging (MRI) demonstrated a large nasal and intracranial tumor, in addition to a separate sellar and suprasellar tumor. The patient was frankly acromegalic. She underwent a first-stage gross total resection of the esthesioneuroblastoma via a combined extended subfrontal and extended endonasal approach, followed by focused radiation therapy. She then returned for endoscopic removal of the GH-secreting pituitary macroadenoma. Conclusion The combined open and endoscopic management of this patient is described and a review of the literature presented. To our knowledge this is the first case of synchronous esthesioneuroblastoma and macroadenoma, in this case GH secreting, described in the literature.

Abstract
CONCLUSIONS Endoscopic techniques seem to be safe approaches for the treatment of esthesioneuroblastomas (ENBs). However, they are intended for selected patients and require extensive experience in base of the skull surgery. OBJECTIVES ENB is a rare tumor of the nasal cavity. The craniofacial approaches remain the gold standard of treatment in multiple centers. Endoscopic endonasal approaches were progressively developed. The main objective of this work was to study the overall survival and recurrence-free period for patients with ENB who underwent endoscopic resection. METHODS We performed a retrospective study from 1996 to 2014, reviewing the patients treated by endonasal endoscopic surgery for ENB. RESULTS Eight patients benefited from endoscopic surgical resection. According to the Kadish classification, one patient was stage A, three patients were stage B, and four patients were stage C. According to the Dulguerov classification, one patient was stage T1, five patients were stage T2, and two were stage T4. Reconstruction of the base of the skull was performed in three patients. No postoperative complications were noted. The mean follow-up period was 95 months. The 5-year overall survival was 87.5% and the 5-year recurrence-free survival was 75%. To date, there have been no local recurrences but two patients had lymph node recurrences. Seven patients are disease-free and one is deceased.

Abstract
OBJECTIVES/HYPOTHESIS To conceive and critically evaluate an adaptation of the split calvarial osteopericranial flap for reconstruction following endoscopic endonasal resection of the anterior skull base. STUDY DESIGN Cadaveric anatomic study. METHODS Five cadavers were embalmed with methanol, and vasculature was injected with latex. Endoscopic endonasal resection of the anterior skull base was performed, followed by reconstruction with a unilateral osteopericranial flap and a contralateral conventional pericranial flap. RESULTS Rigid reconstruction was achieved in all specimens. Osteoplastic flap harvest was made more reliable by drilling the diploe below the graft with a curved bur. Dimensions of the bony flap were ideally shorter and wider than the defect, allowing for flap inset and rigid support by the orbits without compromise of the flap vascular supply. Endoscopic inset of the flap is feasible via nasion-frontal osteotomy and inlay technique. CONCLUSION Rigid anterior skull base reconstruction via split calvarial osteopericranial flap is adaptable to current endoscopic techniques. This provides more anatomic reconstruction than current methods and may lead to decreased complication rates following anterior skull base resection.

Abstract
Objectives We present a case of olfactory preservation after a unilateral transcribriform transethmoidal endoscopic resection of esthesioneuroblastoma. We also discuss the oncologic results of endoscopic and transcranial approaches and describe the potential benefits and limitations of an endoscopic approach. Setting Single academic medical center. Participant and Design The clinical course of a 28-year-old patient who underwent endoscopic en bloc resection of esthesioneuroblastoma through a unilateral transcribriform transethmoidal approach was reviewed. Results Imaging demonstrated a left-sided nasal mass with cribriform plate involvement (Kadish C). Intraoperatively, the left olfactory bulb and epithelium were sacrificed. Negative frozen sections were obtained from the right olfactory epithelium and dura surrounding the right olfactory bulb. Reconstruction was performed using a multilayered closure of fascia, rigid buttress, and nasoseptal flap. Histology was consistent with esthesioneuroblastoma. Postoperative clinical evaluation, endoscopy, and magnetic resonance imaging demonstrated no evidence of residual or recurrent tumor at 18 months. The UPSIT smell testing revealed normal olfaction preoperatively, moderate microsomia at 3 months postoperatively, and mild microsomia at 18 months postoperatively. Conclusions Endoscopic resection of esthesioneuroblastoma has demonstrated similar oncologic control while reducing postoperative morbidity and mortality over transcranial approaches. This case reveals the potential to preserve olfaction while achieving en bloc endoscopic resection of early stage esthesioneuroblastoma.

Abstract
Esthesioneuroblastoma (ENB) involving the anterior skull base is a rare malignant tumour derived from the olfactory epithelium. The gold standard of surgical treatment is currently craniofacial resection (CFR), which allows efficient removal of the tumour but entails significant morbidity. To reduce morbidity combined with good visualization of tumour limits removal, endonasal endoscopy resection (EER) has developed. The objective of this work was (1) to describe the EER surgical procedure, the morbidity, and the limitations of this endoscopic approach as compared with CFR, (2) analyse recurrences to define risk factors of recurrences and (3) to discuss a therapeutic decision algorithm. Retrospective series of 18 patients with ENB endoscopically treated in a university tertiary referral centre over 13 years. Fifteen of those underwent radiotherapy. Epidemiological data, clinical and imaging findings, histology, treatment modalities and outcome of patients were studied. Mean follow-up was 31 months. Morbidity was mainly related to radiotherapy. Three recurrences were detected: one bone and one sylvian metastasis, and a local recurrence in a patient not irradiated. One recurrence spread through leptomeningeal propagation. Dural extension and frontal invasion were significantly associated with recurrences (p = 0.001 and p = 0.019, respectively). Patients with dural extension or frontal invasion should receive aggressive treatment. With a low rate of perioperative morbidity and efficient local control, EER seems to be a promising approach for selected cases of ENB.

Abstract
A variety of histologic tumor types are present in the anterior skull base. Primary tumors of this area may be derived from the bone, paranasal sinuses, nasopharynx, dura, cranial nerves, pituitary gland and brain. Symptoms are caused mostly through mass effect but, if the tumor becomes aggressive, also through invasion. Selection of surgical approaches to the anterior skull base is based upon balancing risk reduction with maximizing extent of resection. Here we review a spectrum of neoplastic entities found in the anterior skull base in adults and discuss clinical and radiographic presentation, treatment options, and outcomes. Surgical resection remains the mainstay in treatment of these tumors, particularly in the hands of experienced surgeons exercising proper patient and case selection.

Int Forum Allergy Rhinol 2014; 4:517-21.

Abstract
BACKGROUND The endoscopic modified Lothrop procedure (EMLP) is well established for resistant frontal sinus disease and anterior skull base (ASB) exposure. However, this technique may be unnecessarily aggressive by removing avoidable sinonasal structures in select cases. Previously, in a cadaveric study, we proposed a modification of the EMLP, termed the modified subtotal-Lothrop procedure (MSLP), to access the ASB and to address complex frontal sinus disease, for which access to the bilateral frontal sinus posterior table is required. This study provides a step-by-step description of this technique, and presents our experience in 5 patients who underwent this approach. METHODS A retrospective analysis was performed at a tertiary referral center on all patients undergoing endoscopic ASB resection and complex frontal sinus surgeries between May 2011 and May 2013. Of 8 patients identified who underwent an MSLP, 5 had at least 1-year follow-up. RESULTS All patients underwent successful ASB exposure via the MSLP without complications and preservation of one frontal sinus recess. Adequate access to the bilateral posterior frontal sinus table was achieved in all cases. A patent frontal sinus drainage pathway could be assessed endoscopically after a mean follow-up of 18.6 (range, 12-27) months. CONCLUSION The MSLP is a feasible approach for exposure of the ASB and accessing complex frontal sinus pathology. This modification provides adequate ASB exposure and surgical maneuverability similar to the EMLP, while preserving one frontal sinus recess. This modification was successful in providing adequate exposure and maneuverability as well as maintaining frontal sinus patency in this small cohort.
