Objectives  The aim of this study was to identify the reasons for patient messages, phone calls, and emergency department (ED) visits prior to the first postoperative visit following discharge after endoscopic transnasal transsphenoidal (eTNTS) surgery. Design  This is a retrospective review of patients at a tertiary care academic center who underwent eTNTS for resection of a sellar region tumor between May 2020 and August 2021. Patient, tumor, and surgical characteristics were collected, along with postoperative, postdischarge, and readmission information. Regression analyses were performed to investigate risk factors associated with postdischarge phone calls, messages, ED visits, and readmissions. Main Outcome Measures  The main outcomes were the number of and reasons for phone calls, patient messages, and ED visits between hospital discharge and the first postoperative visit. We additionally determined whether these reasons were addressed in each patient's discharge instructions. Results  A total of 98 patients underwent eTNTS during the study period. The median length of hospital stay was 2 days (interquartile range [IQR]: 1-4 days), at which point most patients (82%) were provided with eTNTS-specific discharge instructions. First postoperative visit took place 9 days after discharge (IQR: 7-10 days). Within that time, 54% of patients made at least one phone call or sent at least electronic message and 17% presented to the ED. Most common reasons for call/message were nasal care, appointment scheduling, and symptom and medication questions. Conclusion  Through this work, we highlight the most common reasons for resource utilization via patient phone calls, messages, and ED visits among our cohort to better understand any shortfall or gap in the discharge process that may reduce these events.

PurposeSpheno-orbital meningiomas are rare tumors, accounting for up to 9% of all intracranial meningiomas. Patients commonly present with proptosis, and visual deficits. These slow growing tumors are hard to resect due to extension into several anatomical compartments, resulting in recurrence rates as high as 35-50%. Although open surgical approaches have been historically used for resection, a handful of endoscopic approaches have been reported in recent years. We aimed to review the literature and describe a case of spheno-orbital meningioma with severe vision loss which was resected with an endoscopic endonasal approach achieving complete resolution of visual symptoms.MethodsA systematic review of literature was conducted in accordance with the PRISMA guidelines. PubMed, Cochrane, and Web of Science databases were queried for spheno-orbital meningiomas resected via an endoscopic endonasal approach. Furthermore, the presentation, surgical management, and post-operative outcomes of a 53-year-old female with a recurrent spheno-orbital meningioma are described.ResultsThe search yielded 26 articles, of which 8 were included, yielding 19 cases. Average age at presentation was 60.5 years (range: 44-82), and 68.4% of patients were female. More than half of the cases achieved subtotal resection. Common complications associated with endoscopic endonasal surgery included CN V2 or CN V2/V3 hypoesthesia. Following surgical intervention, visual acuity and visual field remained stable or improved in the majority of the patients.ConclusionEndoscopic approaches are slowly gaining momentum for treatment of spheno-orbital meningiomas. Further studies on the clinical benefits of this approach on patient outcomes and post-operative complications is warranted.

Airway epithelia express intrinsic antimicrobial and nutrient-sequestering factors, which contribute to the host defense of the respiratory tract. Hepcidin is an endogenous peptide hormone that serves as a key regulator of iron metabolism, and ferroportin and ZIP8 are iron transporters. All exhibit innate antimicrobial activity. The purpose of this pilot study is to determine if molecules involved in iron regulation are expressed within sinus epithelia and to compare levels of expression between patients with and without chronic rhinosinusitis (CRS). Sinus mucosa was obtained from patients with (n = 19) and without (n = 14) CRS. Real-time polymerase chain reaction following RNA extraction was used to quantify expression of hepcidin, ferroportin, and ZIP8 mRNA. Hepcidin, ferroportin, and ZIP8 were all detected in the sinus epithelia of patients with and without CRS. However, only ZIP8 was significantly changed in CRS, with a 2.5-fold mean increase in mRNA expression relative to controls (P = .005). These findings suggest that ZIP8 may play a role in the innate epithelial defense of the paranasal sinuses.

Objective: To assess the long‐term safety and effectiveness of temperature‐controlled radiofrequency (TCRF) neurolysis of the posterior nasal nerve (PNN), a minimally invasive treatment for chronic rhinitis. Methods: A prospective, single‐arm study of 129 patients at 16 centers (United States, Germany) was conducted. Patient‐reported outcome measures were the 24‐h reflective total nasal symptom score (rTNSS) and mini rhinoconjunctivitis quality of life questionnaire (MiniRQLQ). Postnasal drip and cough symptoms were assessed using a 4‐point scale. Results: The mean pretreatment rTNSS was 7.8 (95% CI, 7.5–8.1). The significant rTNSS treatment effect at 3 months (−4.2 [95% CI, −4.6 to −3.8]; p < 0.001) was sustained through 2 years (−4.5 [95% CI, −5.0 to −3.9]; p < 0.001), a 57.7% improvement. At 2 years, the proportion of patients with a minimal clinically important difference (MCID) of ≥30% improvement in rTNSS from baseline was 80.0% (95% CI, 71.4%–86.5%). Individual postnasal drip and cough symptom scores were significantly improved from baseline through 2 years. The proportion of patients who reached the MCID for the MiniRQLQ (≥0.4‐point improvement) at 2 years was 77.4% (95% CI, 68.5%–84.3%). Of 81 patients using chronic rhinitis medications at baseline, 61.7% either stopped all medication use (28.4%) or stopped or decreased (33.3%) use of ≥1 medication class at 2 years. No device/procedure‐related serious adverse events were reported throughout 2 years. Conclusion: TCRF neurolysis of the PNN resulted in sustained improvements in chronic rhinitis symptom burden and quality of life through 2 years, accompanied by a substantial decrease in medication burden.

Objectives: Dysbiosis of the sinonasal microbiome has been implicated in the pathogenesis of chronic rhinosinusitis (CRS). However, the mycobiome remains largely understudied, and microbial alterations associated with specific CRS subtypes have yet to be delineated. The objective of this study is to investigate the fungal and bacterial microbiome of sinus mucosa in CRS patients with and without nasal polyposis (CRSwNP and CRSsNP) versus healthy controls. Methods: Sinus mucosa was obtained from 92 patients (31 CRSsNP, 31 CRSwNP, and 30 controls) undergoing endoscopic sinus/skull base surgery. Data regarding demographics, Lund‐MacKay scores, and histopathology were collected. Fungal and bacterial microbiome analysis was performed utilizing internal transcribed spacer amplicon and 16S rRNA sequencing. Results: Beta diversity of the sinonasal mycobiome differed significantly between CRS and controls (p = 0.001) and between CRSwNP and controls (p = 0.049), but not between CRSwNP and CRSsNP (p = 0.32) nor between CRSsNP and controls (p = 0.06). With respect to the bacterial microbiome, significantly lower alpha diversity was observed between CRS and controls (p < 0.001), CRSwNP versus controls (p < 0.001), and CRSsNP versus controls (p < 0.001). Beta diversity was also significantly different at the genus level between CRSwNP and CRSsNP (p = 0.019), CRSwNP and controls (p = 0.002)), and CRSsNP and controls (p < 0.001). However, alpha and beta diversity did not differ significantly between CRS patients with/without eosinophils or correlate with Lund‐MacKay scores. Conclusions: Differences in mycobiota diversity in CRS patients in comparison with controls suggest that alterations in the mycobiome may contribute to disease pathogenesis. Our findings also confirmed that diminished diversity among bacterial communities is associated with CRS and that significant differences are present in microbial composition between CRSwNP and CRSsNP.

Background: Many people with cystic fibrosis (PwCF) have chronic rhinosinusitis (CRS). CRS requires additional management beyond that of pulmonary disease and leads to increased utilization of healthcare resources. Elexacaftor/tezacaftor/ivacaftor (ETI) is a highly effective modulator therapy that has been shown to improve CRS in PwCF. However, the impact of ETI on rhinologic healthcare utilization is understudied. Objective: To compare rates of rhinologic healthcare utilization and procedures among PwCF prior to and after initiating ETI therapy. Methods: A single-center, cohort study investigating adult PwCF was performed in January 2023. Demographics, clinical characteristics, and data related to CF treatment were retrospectively abstracted. Characteristics of the cohort were compared over 2 periods: the 12-months prior to ETI initiation and the 12-months after ETI initiation. Post-ETI data were linearly extrapolated if a subject had not yet completed the full 12 months of ETI. Paired t-testing, Wilcoxon signed rank testing, and regression analysis were performed. Results: Of 126 PwCF, 98 (77.8%) were on ETI therapy and 35 (27.7%) were both on ETI and concurrently followed by the rhinology service (ETI-ENT). Rhinology clinic visits (P =.007) and frequency of obtaining nasal cultures (P =.046) decreased for the ETI-ENT cohort after initiating ETI treatment. There were no significant changes in the number of endoscopic sinus surgeries (P =.452) performed. Beyond ETI use, regression analysis did not identify any factors associated with changes in utilization. Conclusion: Aspects of rhinology healthcare utilization by PwCF decreased after initiation of ETI therapy. Additional studies are needed to determine rhinologic healthcare requirements for PwCF who remain on ETI for the long-term and to evaluate larger cohorts of PwCF on ETI. [ABSTRACT FROM AUTHOR]

This article discusses the use of different techniques for skull base reconstruction in endoscopic pituitary surgery and their association with cerebrospinal fluid (CSF) leaks. The Hadad-Bassagasteguy nasoseptal flap (NSF) has been effective in reducing CSF leaks, but there is limited data on the appearance of different reconstruction techniques on MRI and their relationship to CSF leak rates. The study reviewed patient data and imaging to compare the vascularization patterns of free mucosal grafts (FMG) and NSF, and found that patients with NSF reconstruction had higher rates of intraoperative CSF leaks. However, there was no association between patterns of flap enhancement on MRI and CSF leaks. FMGs showed a predictable change in enhancement pattern over 3 months, while NSFs without flap enhancement at 1 week still demonstrated neovascularization without increased risk of complications.

Objective While postoperative cerebrospinal fluid (CSF) leak rates of pituitary tumors have been frequently studied, there are fewer studies examining postoperative CSF leak rates for extrasellar tumors. The purpose of this study was to identify risk factors for the development of postoperative CSF leak in patients undergoing endoscopic surgery for extrasellar tumors. Methods A retrospective chart review was done for patients who underwent endoscopic resection for extrasellar tumors between 2008 and 2020. Age, gender, tumor type, tumor location, tumor size, reconstruction technique, medical comorbidities, and other potential risk factors were identified. Data was analyzed to identify significant risk factors for development of postoperative CSF leak. Results There were 100 patients with extrasellar tumors who developed intraoperative CSF leaks. Seventeen patients (17%) developed postoperative CSF leaks. Leaks occurred at a median of 2 days following surgery (range 0–34 days). Clival tumors had a significantly higher incidence of postoperative leak than those in other sites (p < 0.05). There were no significant differences in other locations, body mass index, tumor size, reconstruction technique, medical comorbidities, or other factors. There were nearly twice as many intraoperative grade III leaks in those who developed postoperative CSF leak, but this was not statistically significant (p = 0.12). Conclusion Extrasellar tumors, particularly clival tumors, have a higher rate of postoperative CSF leak than pituitary tumors. Prophylactic lumbar drains can be considered for patients at high risk for developing postoperative CSF leak. [ABSTRACT FROM AUTHOR]

Objective: This study aims to identify clinical predictors of treatment response to Eustachian Tube Balloon Dilation (ETBD) as measured by changes in Eustachian Tube Dysfunction Questionnaire-7 (ETDQ-7) scores. Methods: One hundred thirteen patients who underwent ETBD at an institution from 2017 to 2021 completed ETDQ-7 pre- and post-operatively. We conducted multivariable regression analyses with ETDQ-7 normalization (<2.1 post-op), minimum clinically important difference (MCID) (>0.5 pre-op – post-op), and quantitative improvement in ETDQ-7 score as outcome variables. Pre-operative ETDQ-7 score, tympanogram type, chronic otitis media, chronic rhinosinusitis (CRS), inferior turbinate hypertrophy, deviated septum, allergic rhinitis, and rhinorrhea were included as covariates. Models controlled for age, sex, ethnicity, prior ear or sinus surgery, and follow-up duration. Results: The mean age was 49 years old. 51% were females, and all patients had pre-operative ETDQ-7 above 2.1. After a mean follow-up period of 13 months, 77% achieved MCID and 37% had normalized. Higher pre-operative ETDQ-7 score was associated with greater ETDQ-7 score improvement (B = 0.60, 95% CI = [0.37, 0.83]) and greater odds of achieving MCID (aOR = 1.65; 95% CI = [1.06, 2.59]). A history of CRS improved chances of achieving MCID (aOR = 4.53; 95% CI = [1.11, 18.55]) and a history of chronic otitis media predicted increased odds of ETDQ-7 normalization (aOR = 2.88; 95% CI = [1.09, 7.58]). Conclusions: Our findings suggest that ETBD was highly effective among patients with pre-operative ETDQ-7 above 2.1. Furthermore, higher pre-operative ETDQ-7 score, CRS, and chronic otitis media predicted more favorable symptomatic benefit from ETBD. These factors may be important to consider when counseling potential candidates for this procedure. [ABSTRACT FROM AUTHOR]
