Abstract
Background and objective Transsphenoidal surgery, including endoscopic and microscopic resection, is the first choice of treatment for pituitary tumors. With the widespread application of neuroendoscopy in recent decades, there has been a trend to replace microscopes. In clinical practice, we have found that in transsphenoidal surgery for non-invasive microadenomas and macroadenomas, microscopy can achieve a higher total resection rate, shorter operation time, lower incidence of postoperative complications, and faster recovery of olfaction. This study aimed to explore the selection of endoscopes and microscopes for non-aggressive transsphenoidal surgery for pituitary adenomas and the factors affecting olfactory recovery. Methods From August 2019 to October 2022, 93 patients with non-aggressive microadenomas and macroadenomas via the transsphenoidal approach were selected from the First Affiliated Hospital of Harbin Medical University and treated with rich experience in pituitary tumor subspecialty microscopy and endoscopic surgery. Different surgical methods were used to divide the patients into microscopic (n = 35) and endoscopic (n = 58) groups. The total tumor removal rate, intraoperative blood loss, operation time and cost, postoperative hospital stay, recovery of visual function, postoperative changes in hormone levels, complication rate, and recovery from complications 3 months after the operation were compared between the two groups. Results There were no significant differences in the tumor removal rate, postoperative visual acuity, and visual field recovery between the two groups (p > 0.05). There was a significant difference in the recovery rate of olfactory function between the two groups 3 months after the operation (p < 0.05), and there was no significant difference in the incidence of other complications (p > 0.05); Compared with the two groups, the microscope group had shorter operation time, longer postoperative hospital stay, less average operation cost and less blood loss, and the difference was statistically significant (p < 0.05). The position of the nasal septum mucosal flap incision was a risk factor for hyposmia 3 months after the operation. Conclusion Microsurgery and endoscopic surgery are suitable surgical treatments for nonaggressive microadenomas and macroadenomas. The total tumor removal and postoperative hormone remission rates of the two surgical methods were approximately the same. However, the microsurgery group had a shorter operation time, less intraoperative blood loss, faster olfactory function recovery, and a lower average operation cost. The position of the nasal septal mucosal flap incision was a risk factor for hyposmia at 3 months postoperatively. Hyposmia is less likely to occur when the superior edge of the nasal septal mucosal flap incision is not higher than the lower edge of the ipsilateral superior turbinate.

Abstract
ABSTRACT Mucoceles are fluid filled cysts with numerous etiologies that can erode bone and if left untreated, can lead to infraorbital and intracranial complications. With limited cases published in the medical literature, our patient with a frontonasal mucocele expanding from the frontal sinus to the nasal dorsum with erosion of the nasal bones and upper lateral cartilages, provides an opportunity for evidence-based diagnosis and treatment. We present a 24-year-old female with a nasal mass destroying numerous nasal structures. Three surgical approaches were considered: open rhinoplasty, bicoronal approach, and Lynch excision; the latter executed with subsequent total nasal reconstruction. Bone, septal cartilage, and temporalis fascia were utilized to provide structural support and a posterior nasal septal flap was incorporated to maintain a blood supply. Integrity of nasal structure and cosmesis as well as recurrence of disease were monitored during postoperative visits.

Endoscopic endonasal cyst fenestration into the sphenoid sinus using the mucosa coupling method for symptomatic Rathke's cleft cyst: a novel method for maintaining cyst drainage to prevent recurrence. J Neurosurg 2020; 133:1710-1720.

Abstract
OBJECTIVE Rathke's cleft cyst (RCC) is a benign cystic lesion with a relatively high incidence of local recurrence that occasionally requires repeat surgery. To prevent recurrence, simple cyst fenestration and drainage of the cyst contents to the sphenoid sinus is recommended, but it occasionally recurs. The authors postulated that obstruction of fenestration is a main cause of recurrence, and they developed a method, named the "mucosa coupling method (MC method)," that maintains persistent drainage. In this method, the RCC epithelium and the mucosa of the sphenoid sinus are connected, which promotes re-epithelialization between the two epithelia, maintaining persistent drainage. The outcome of this method was compared with that of conventional cyst fenestration. METHODS In a consecutive series of 40 patients with RCC, the surgical strategy was changed during the study period: from December 2009 to September 2014 (the conventional period), 24 patients were scheduled to be treated using the conventional fenestration method, whereas from September 2014 to September 2017 (the MC period), 16 patients were scheduled to be treated using the MC method. However, because of an intraoperative CSF leak, the fenestration was closed during surgery in 3 patients in the conventional period and 2 in the MC period; therefore, these 5 patients were excluded from the analysis. Twenty-one patients treated with the conventional fenestration method (conventional group) and 14 patients treated with the MC method (MC group) were analyzed. All patients regularly underwent MRI after surgery to detect reaccumulation of cyst contents. The rate of reaccumulation with and without reoperation, visual outcomes, endocrinological outcomes, and postoperative complications were compared between these two groups. RESULTS The median follow-up period in all 35 patients was 48.0 months (range 1-96 months), 54.0 months (range 1-96 months) in the conventional group and 35.5 months (range 12-51 months) in the MC group. No reaccumulation was detected on MRI in the 14 patients in the MC group, whereas it was noted in 9 (42.9%) of 21 patients in the conventional group, and 2 of these 9 patients required repeat surgery. There were no significant differences in visual and endocrinological outcomes and complications between these two groups. CONCLUSIONS The MC method for RCC is effective for preventing obstruction of cyst fenestration, which contributes to preventing cyst reaccumulation. Furthermore, this method is equivalent to the conventional fenestration method in terms of visual and endocrinological outcomes and the complication rate.

Abstract
Background The expanded endoscopic endonasal transplanum transtuberculum approach allows tumor removal by minimally invasive procedures. A large dural and bone defect is created during the surgical procedure, increasing the risk of postoperative cerebrospinal fluid (CSF) leakage. Objective The aim of this study is to describe a surgical technique and complications observed in patients undergoing endonasal resection of planum sphenoidale and/or tuberculum sellae meningiomas. Methods A retrospective analysis was performed of patients with planum sphenoidale and/or tuberculum sellae meningiomas after expanded endoscopic endonasal resection between June 2013 and August 2018, in which autologous grafts, fascia lata inlay, and nasoseptal flap onlay were used for closure of skull base defects. Results Ten patients were included in the analysis. No cases of postoperative CSF leakages or meningitis were reported, whereas two patients evolved with postoperative infectious complications (fungal ball in right frontal sinus and brain abscess). The skull base defect created for resection measured, on average, 3.58 cm2. Conclusion Our experience suggests that closure of skull base defects using combined fascia lata inlay and nasoseptal flap onlay is effective for preventing postoperative CSF leakage in resection of planum sphenoidale and/or tuberculum sellae meningiomas, and offers high reproducibility due to its low cost.

Abstract
INTRODUCTION Over the last two decades there has been a gradual shift from the traditional microscopic approach toward the use of endoscopic endonasal approach for resection of pituitary adenomas. Multiple medical and surgical complications can occur following endoscopic transsphenoidal resection of adenomas. AREAS COVERED We discuss the evolution of the surgical practice from the use of the 'microscope' to the 'endoscope' in the resection of pituitary adenomas. We present a comprehensive review of the medical and surgical complications following surgery with particular emphasis on both the prevention and management of electrolyte disturbance, cerebrospinal fluid leak and the rare but dreaded complication of internal carotid injury (ICA). We also searched the PubMed database to identify relevant literature between 1984 and 2019. EXPERT OPINION Use of endoscope compared with microscope may be associated with better preservation of pituitary gland function with similar extent of resection. Overall medical and surgical complications can be safely managed in high volume centers in association with endocrinologists and skull base trained otolaryngologists. Understanding of anatomico-technical nuances and meticulous surgical technique are important toward preventing ICA injury. Ongoing surgical and technical developments coupled with imaging advances will likely lead to better future outcomes for patients with functioning and nonfunctioning adenomas.

Abstract
BACKGROUND Endoscopic skull-base surgery (ESBS) is employed in the management of diverse skull-base pathologies. Paralleling the increased utilization of ESBS, the literature in this field has expanded rapidly. However, the rarity of these diseases, the inherent challenges of surgical studies, and the continued learning curve in ESBS have resulted in significant variability in the quality of the literature. To consolidate and critically appraise the available literature, experts in skull-base surgery have produced the International Consensus Statement on Endoscopic Skull-Base Surgery (ICAR:ESBS). METHODS Using previously described methodology, topics spanning the breadth of ESBS were identified and assigned a literature review, evidence-based review or evidence-based review with recommendations format. Subsequently, each topic was written and then reviewed by skull-base surgeons in both neurosurgery and otolaryngology. Following this iterative review process, the ICAR:ESBS document was synthesized and reviewed by all authors for consensus. RESULTS The ICAR:ESBS document addresses the role of ESBS in primary cerebrospinal fluid (CSF) rhinorrhea, intradural tumors, benign skull-base and orbital pathology, sinonasal malignancies, and clival lesions. Additionally, specific challenges in ESBS including endoscopic reconstruction and complication management were evaluated. CONCLUSION A critical review of the literature in ESBS demonstrates at least the equivalency of ESBS with alternative approaches in pathologies such as CSF rhinorrhea and pituitary adenoma as well as improved reconstructive techniques in reducing CSF leaks. Evidence-based recommendations are limited in other pathologies and these significant knowledge gaps call upon the skull-base community to embrace these opportunities and collaboratively address these shortcomings.

Abstract
The evolution of expanded endoscopic skull base surgery has enabled development of minimally invasive approaches for resection of large skull base tumors with the nasoseptal flap proving to be an indispensable tool in skull base reconstruction. We here present our experience of sphenoid mucocele development after skull base reconstruction with the nasoseptal flap along with a comprehensive review of the limited literature on the same. With the expanding scope of endoscopic skull base surgery, the nasoseptal flap is increasingly being used for reconstruction. Despite adherence to standard recommendations and use of meticulous technique during flap placement, the potential risk of mucocele formation under the flap should always be borne in mind. In our experience, displacement of the flap pedicle could lead to ostial obstruction and mucocele formation. Hence, in addition to meticulous technique, a close follow up of such patients via nasal endoscopy or imaging is important to further our knowledge and understanding of the long-term effects and complications of this flap.

Abstract
Paranasal sinus mucoceles are benign, expansive, cystic lesions which arise from retention of mucus secretions. They arise primarily in the setting of cystic degeneration of the sinus mucosa or secondarily in the setting of obstruction of the sinus ostium due to mucosal trauma or chronic inflammation. Septal mucoceles are rare. Only 10 cases to our knowledge have previously been reported. Patients are exclusively male, in their middle years, usually with a history of nasal trauma or nasal surgery. Nasal obstruction followed by headache present for 3 months to a year are the most common presenting symptoms. Here, we present a case of septal mucocele with dystrophic bone formation in a 57-year-old man arising 35 years after open septorhinoplasty treated successfully with total excision via an endoscopic, endoseptal approach. A review of the available literature was conducted to provide a consolidated update on diagnosis and management.

Abstract
OBJECTIVE At our institution, skull base reconstruction using a free mucosal graft from the nasal cavity floor has been the standardized technique after pituitary adenoma resection via transsellar approach. In this study, the expected appearance of the reconstruction on postoperative magnetic resonance imaging (MRI) scans is described and its integrity and impact on the sinonasal cavity are assessed. METHODS Fifty patients were selected, and their electronic medical records were reviewed for postoperative course, Sino-Nasal Outcome Test-22 (SNOT-22) scores, and nasal endoscopy reports. A total of 116 postoperative MRI scans were available to evaluate 1) the appearance and thickness of the graft, 2) the enhancement of the graft, and 3) the T2 signal in sphenoid sinus as a potential indication for inflammatory disease. RESULTS There was no significant change in the thickness of the graft over time. Except for the 7 scans that were obtained without intravenous contrast, all scans showed enhancement of the graft. About half of the patients showed persistent T2 hyperintense signal at 12 and 24 months. However, this finding was not clinically significant, because postoperative SNOT-22 scores showed minimal sinonasal impact. CONCLUSIONS Postoperative MRI surveillance scans showed a stable appearance of the graft that mimics the native mucosa, with enhancement through time, reflecting its robust vascularization and integration to the skull base. Although persistent T2 hyperintense signal was detected in the sphenoid sinus, clinical evidence based on nasal endoscopy reports and SNOT-22 scores indicated minimal sinonasal morbidity.

Abstract
OBJECTIVE The purpose of this study was to review the clinical characteristics, treatment methods, and surgical outcomes of sphenoid sinus mucocele after transsphenoidal pituitary surgery. PATIENTS AND METHODS A total of 404 patients who underwent transsphenoidal pituitary surgery between January 2010 and December 2016 were identified. Among them, 5 patients with sphenoid sinus mucocele were included in this study. In our hospital, a single-nostril endonasal endoscopic wide sphenoidotomy is routinely used for pituitary tumor surgery. RESULTS The occurrence rate of sphenoid sinus mucocele was 1.2% (5/404). Of the 5 patients, 2 were males and 3 were females. Four lesions (80.0%) were located in the right sphenoid sinus and 1 lesion (20.0%) was located in the left sphenoid sinus. Endoscopic marsupialization for sphenoid sinus mucocele was performed under local anesthesia in all patients. There were no major complications resulting from the surgical intervention, and there was no recurrence at the time of the last follow-up. CONCLUSION Sphenoid sinus mucocele after endonasal transsphenoidal pituitary surgery is an extremely rare complication. Nasal endoscopy and MRI are useful for diagnosing this lesion. Endoscopic marsupialization is a safe and effective procedure for sphenoid sinus mucocele after endonasal transsphenoidal pituitary surgery.

Abstract
OBJECTIVES The utilization of the nasoseptal flap (NSF) in endoscopic anterior skull base surgery (EASB) has resulted in reduced rates of postoperative cerebrospinal fluid leak (CSF). The long-term impact on sinonasal function after surgery remains incompletely defined. METHODS A consecutive series of patients undergoing EASB with NSF and with at least 3 years follow-up was prospectively evaluated. Patient demographics, pre- and postoperative Sino-nasal Outcome Test-22 (SNOT-22) scores, Lund-Mackay scores (LMS), CSF leak, and sinonasal complications were analyzed. RESULTS A total of 46 patients undergoing EASB with NSF met inclusion criteria. The mean follow-up was 67.4 months (range 39-90, standard deviation [SD] 14.2 months). No statistically significant differences were noted between the mean overall pre- (16) and postoperative SNOT-22 scores (18). SNOT-22 scores improved in 27 patients (58.7%), deteriorated in 17 patients (37.0%) and stayed the same in two patients (4.3%). Deterioration in SNOT-22 scores was greater in younger (mean change + 7.2 [SD17.4] vs. older patients -3.4 [SD 7.5], P = 0.010). A statistically significant increase in LMS was noted (mean preoperative LMS0.9 vs. mean postoperative LMS 2.2, P = 0.001). The LMS decreased in nine patients (19.6%), increased in 22 patients (47.8%), and remained the same in 15 patients (32.6%). One patient (2.2%) developed a postoperative CSF leak following resection of metastatic skull base lesion and was successfully treated with placement of a lumbar drain, Foley catheter balloon, and strict bed rest. One patient (2.2%) developed a postoperative mucocele requiring decompression 3 years after initial surgery. CONCLUSION Whereas long-term sinonasal quality of life is overall improved in the majority of patients following NSF use for EASB, younger patients show higher incidence of deterioration. Increased sinus opacification on imaging is generally noted and may require continued follow-up and management. The incidence of reoperation for symptomatic mucocele formation is low.

Abstract
OBJECTIVE The vascularized nasoseptal flap (NSF) has become the workhorse for skull base reconstruction during endoscopic endonasal surgery (EES) of the ventral skull base. Although infrequently reported, as with any vascularized flap the NSF may undergo ischemic necrosis and become a nidus for infection. The University of Pittsburgh Medical Center's experience with NSF was reviewed to determine the incidence of necrotic NSF in patients following EES and describe the clinical presentation, imaging characteristics, and risk factors associated with this complication. METHODS The electronic medical records of 1285 consecutive patients who underwent EES at the University of Pittsburgh Medical Center between January 2010 and December 2014 were retrospectively reviewed. From this first group, a list of all patients in whom NSF was used for reconstruction was generated and further refined to determine if the patient returned to the operating room and the cause of this reexploration. Patients were included in the final analysis if they underwent endoscopic reexploration for suspected CSF leak or meningitis. Those patients who returned to the operating room for staged surgery or hematoma were excluded. Two neurosurgeons and a neuroradiologist, who were blinded to each other's results, assessed the MRI characteristics of the included patients. RESULTS In total, 601 patients underwent NSF reconstruction during the study period, and 49 patients met the criteria for inclusion in the final analysis. On endoscopic exploration, 8 patients had a necrotic, nonviable NSF, while 41 patients had a viable NSF with a CSF leak. The group of patients with a necrotic, nonviable NSF was then compared with the group with viable NSF. All 8 patients with a necrotic NSF had clinical and laboratory evidence indicative of meningitis compared with 9 of 41 patients with a viable NSF (p < 0.001). Four patients with necrotic flaps developed epidural empyema compared with 2 of 41 patients in the viable NSF group (p = 0.02). The lack of NSF enhancement on MR (p < 0.001), prior surgery (p = 0.043), and the use of a fat graft (p = 0.004) were associated with necrotic NSF. CONCLUSIONS The signs of meningitis after EES in the absence of a clear CSF leak with the lack of NSF enhancement on MRI should raise the suspicion of necrotic NSF. These patients should undergo prompt exploration and debridement of nonviable tissue with revision of skull base reconstruction.

Abstract
To maximize outcomes from endoscopic skull base surgery, careful early postoperative management is critically important. Standardized postoperative regimens are lacking. The type of reconstruction and presence and type of cerebrospinal fluid leak dictate management. If a leak is encountered intraoperatively, patients should avoid maneuvers that increase intracranial pressures for at least 1 month. Early postoperative care focuses on minimizing and managing nasal crusting. This article reviews the evidence in the literature on postoperative management, complications, and quality of life after surgery, and outlines our experience in the management of patients after endoscopic skull base surgery.

Postoperative otorhinolaryngologic complications in transnasal endoscopic surgery to access the skull base. Braz J Otorhinolaryngol 2016; 83:349-355. [PMID: 27320654 PMCID: PMC9444793 DOI: 10.1016/j.bjorl.2016.04.020] [Citation(s) in RCA: 30] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/07/2016] [Revised: 04/08/2016] [Accepted: 04/14/2016] [Indexed: 12/02/2022] Open
Abstract
Introduction The large increase in the number of transnasal endoscopic skull base surgeries is a consequence of greater knowledge of the anatomic region, the development of specific materials and instruments, and especially the use of the nasoseptal flap as a barrier between the sinus tract (contaminated cavity) and the subarachnoid space (sterile area), reducing the high risk of contamination. Objective To assess the otorhinolaryngologic complications in patients undergoing endoscopic surgery of the skull base, in which a nasoseptal flap was used. Methods This was a retrospective study that included patients who underwent endoscopic skull base surgery with creation of a nasoseptal flap, assessing for the presence of the following post-surgical complications: cerebrospinal fluid leak, meningitis, mucocele formation, nasal synechia, septal perforation (prior to posterior septectomy), internal nasal valve failure, epistaxis, and olfactory alterations. Results The study assessed 41 patients undergoing surgery. Of these, 35 had pituitary adenomas (macro- or micro-adenomas; sellar and suprasellar extension), three had meningiomas (two tuberculum sellae and one olfactory groove), two had craniopharyngiomas, and one had an intracranial abscess. The complications were cerebrospinal fluid leak (three patients; 7.3%), meningitis (three patients; 7.3%), nasal fossa synechia (eight patients; 19.5%), internal nasal valve failure (six patients; 14.6%), and complaints of worsening of the sense of smell (16 patients; 39%). The olfactory test showed anosmia or hyposmia in ten patients (24.3%). No patient had mucocele, epistaxis, or septal perforation. Conclusion The use of the nasoseptal flap has revolutionized endoscopic skull base surgery, making the procedures more effective and with lower morbidity compared to the traditional route. However, although mainly transient nasal morbidities were observed, in some cases, permanent hyposmia and anosmia resulted. An improvement in this technique is therefore necessary to provide a better quality of life for the patient, reducing potential complications.

Abstract
OBJECTIVE To study the long-term radiological findings after endonasal endoscopic approach to the skull base. MATERIAL AND METHODS Prospective study that included 55 patients who underwent advance endoscopic skull base surgery. All patients were evaluated with MRI before, 3 months and 12 months after surgery. We used the Lund-Mackay staging system for chronic rhinosinusitis to evaluate the paranasal cavities and the sinonasal scoring system to assess sinonasal symptoms. RESULTS Seventeen patients (30.9%) underwent extended endonasal approach that required a nasoseptal flap (NSF) for reconstruction of skull base. At baseline the mean total Lund-Mackay score was 0.63 ± 1.2 (range 0-4), and at 3 and 12 months postoperatively the mean scores were 3.5 ± 3.8 (range 0-14) and 2.0 ± 2.5 (range 0-8) respectively. Patients who needed an NSF for reconstruction had a greater Lund-Mackay score (p<0.05). Moreover, NSF is correlated with sinonasal mucosal thickening and fluid retention at 3 months (r=0.45, p<0.01) and 12 months (r=0.4, p<0.01). Total 5-symptom score (T5SS) was similar between both groups at baseline. Patients with extended endoscopic approach reported more smell loss (40.1 ± 26.2; p<0.05) and posterior nasal discharge (49.3 ± 30.1; p<0.05) than TTEA patients (21.6 ± 30.9 and 22.5 ± 27.5 respectively). CONCLUSIONS We observed that sinus opacity is still present after one year of advance endoscopic skull base surgery but symptoms seems to return to basal after 12 months of follow-up.

Repair and prevention of cerebrospinal fluid leakage in transsphenoidal surgery: a sphenoid sinus mucosa technique. Neurosurg Rev 2015; 39:123-31; discussion 131.

Abstract
Cerebrospinal fluid (CSF) leakage is a common but sometimes serious complication after transsphenoidal surgery (TSS). To avoid this postsurgical complication, we usually repair the CSF leaking area using an autologous material, such as fat, fascia, or muscle graft and sometimes nasonasal septal flap. In this report, we propose a technique using a novel autologous material, sphenoid sinus mucosa (SSM), to repair intraoperative CSF leakage or prevent it postoperatively. On 26 February 2007, we introduced the technique of using SSM to repair or prevent CSF leakage in TSS. Until 30th of June 2014, we performed 500 TSSs for patients with pituitary or parasellar lesions. They were 195 men and 305 women with a mean age of 48.5 years (range, 5-85 years). We used SSM for patching or suturing the arachnoid laceration or dural defect, in lieu of fat or fascia harvested from abdomen or thigh, or made pedicle flap of SSM instead of nasonasal septal flap to cover the sellar floor. Comparing the previous 539 cases not using these techniques before 26 February 2007, intraoperative CSF leakage increased from 49 to 69.4% (p < 0.0001) due to more aggressive surgical technique, mainly related to more extensive approaches and lesion removals, but the rate of using fat was reduced significantly from 35.5 to 19.4% (p = 0.00021) in small or moderate CSF leaks during TSS without increasing the reoperation rate for postoperative CSF leaks (1.86 vs 1.2%, p = 0.45). The technique of using SSM to repair intraoperative CSF leaks or prevent them postoperatively in TSS was considered useful, effective, less invasive, easier for graft harvesting (same surgical field), and providing natural anatomical reconstruction, without potential donor site morbidity. We can recommend it as a standard method for CSF leaks repair and prevention in TSS.

Abstract
PURPOSE OF REVIEW Skull base surgery has undergone a fundamental transformation with the development and rapid adoption of endoscopic endonasal expanded approaches. Defects created from these newer approaches have necessitated an evolution of novel reconstructive techniques, which are reviewed here. RECENT FINDINGS New reconstructive techniques continue to be developed for repairing surgical defects from endoscopic endonasal skull base resections. Improvisations also allow well known flaps to be used in these approaches. Long term outcomes from repair using some of these techniques are now becoming available. SUMMARY Endoscopic resection of previously unapproachable skull base lesions has become possible with advancements in technology, as well as reconstructive methods. These newer techniques may offer improved outcomes and lower morbidity over conventional surgery.

Abstract
OBJECTIVE The endonasal route often provides the most direct and safe approach to skull base pathology. In this article we review the literature with regard to management of the paranasal sinuses in the setting of skull base surgery. METHODS We describe our institutional experience and review the literature of concurrent management of the sinusitis in patients undergoing endoscopic skull base surgery. RESULTS Patients should be optimized preoperatively to ensure the endonasal route is a safe corridor to enter the intracranial cavity. Often the paranasal sinuses can be surgically addressed at the same time as endoscopic skull base surgery. We describe the technical details of management of the paranasal sinuses when addressing skull base pathology. CONCLUSIONS Careful management of the paranasal sinuses throughout the peri-operative course is paramount to optimizing sinonasal function and safety.

Abstract
OBJECTIVES/HYPOTHESIS To analyze complications associated with nasoseptal flap elevation and reconstruction in endoscopic skull base surgery. STUDY DESIGN Case series. METHODS Retrospective chart review of all patients who underwent nasoseptal flap procedure in our institution between 2008 and 2013. RESULTS A total of 121 patients were identified with a mean follow-up time of 10.4 months. Complications associated with this procedure occurred in 33 patients (27%). The majority of complications were related to the septal donor site and included septal perforation, cartilage necrosis, and prolonged crusting. Other complications included intraoperative injury to the flap pedicle (n = 4) or recurrent/persistent cerebrospinal fluid leak occurring in the early postoperative period (n = 7). Long-term quality-of-life data assessed via Sinonasal Outcome Test-22 questionnaires did not reveal notable differences when compared to preoperative scores. CONCLUSION The complication rate associated with nasoseptal flap elevation and inset is higher than previously described. The majority of complications became manifest beyond the immediate postoperative period and were associated with the septal donor site, including septal perforation, prolonged crusting, and cartilage necrosis. We hypothesize that donor site morbidity may be related to compromise of the contralateral septal vascular supply during the procedure. The range and frequency of complications of nasal septal flap surgery should be considered in counseling patients who may receive a nasoseptal flap for skull base reconstruction.

Abstract
Advances in endoscopic skull base (SB) surgery have led to the resection of increasingly larger cranial base lesions, resulting in large SB defects. These defects have initially led to increased postoperative cerebrospinal fluid (CSF) leaks. The development of the vascularized pedicled nasoseptal flap (PNSF) has successfully reduced postoperative CSF leaks. Mucocele formation, however, has been reported as a complication of this technique. In this study, we analyze the incidence of mucocele formation after repair of SB defects using a PNSF. A retrospective review was performed from December 2008 to December 2011 to identify patients who underwent PNSF reconstruction for large ventral SB defects. Demographic data, defect site, incidence of postoperative CSF leaks, and rate of mucocele formation were collected. Seventy patients undergoing PNSF repair of SB defects were identified. No postoperative mucocele formation was noted at an average radiological follow-up of 11.7 months (range, 3–36.9 months) and clinical follow-up of 13.8 months (range, 3–38.9 months), making the overall mucocele rate 0%. The postoperative CSF leak rate was 2.9%. Proper closure of SB defects is crucial to prevent CSF leaks. The PNSF is an efficient technique for these repairs. Although this flap may carry an inherent risk of mucocele formation when placed over mucosalized bone during repair, we found that meticulous and strategic removal of mucosa from the site of flap placement resulted in a 0% incidence of postoperative mucocele formation in our cohort.
