Background: The objective of this study was to evaluate long-term symptom improvements in patients with nasal airway obstruction (NAO) secondary to nasal valve collapse (NVC) following minimally invasive temperature-controlled radiofrequency (TCRF) treatment., Methods: A prospective, single-arm, multicenter study in patients >18 years with NAO due to NVC. Inclusion criteria were response to nasal valve dilation (e.g., modified Cottle maneuver) and baseline Nasal Obstruction Symptom Evaluation (NOSE) Scale score ≥60. Patients were treated in the nasal valve region with a TCRF device and followed through 2 years. A responder was ≥20% reduction NOSE Scale score or ≥1 reduction in severity class., Results: A total of 122 patients were treated and 91 reached 2 years. The mean baseline NOSE Scale score was 80.3 (95% CI, 78.1-82.6). The adjusted mean change in score at 2 years was -45.8 (95% CI, -53.5 to -38.1), p  < 0.001; a 57.0% improvement. The 2-year responder rate was 90.1% (95% CI, 82.3%-94.7%). Significant and sustained symptom improvement was achieved in subpopulations based on sex, age, body mass index, baseline NAO severity, nasal surgery history, NVC mechanism, septal deviation, and other anatomic contributors of NAO. No serious adverse events with a relationship to the study device and/or procedure were reported., Conclusions: Minimally invasive TCRF device treatment of the internal nasal valve for NAO is well tolerated and leads to significant and sustained improvement in NAO symptom severity through 2 years, including in patients with both static and dynamic NVC, septal deviation, turbinate enlargement, or prior nasal surgery., Level of Evidence: 2b., Competing Interests: William C.

Objectives: Current evidence suggests a link between idiopathic intracranial hypertension (IIH) and spontaneous cerebrospinal fluid (sCSF) leak, as well as between IIH and dural venous sinus (DVS) narrowing. However, there are limited data linking DVS narrowing and sCSF leak. This study aims to determine the prevalence of DVS narrowing in patients with sCSF leak., Methods: A retrospective review of all patients with sCSF leak that presented to a tertiary academic center from 2008 to 2019. Preoperative imaging was independently reviewed by two neuroradiologists to evaluate for DVS narrowing. Available literature was used to estimate the prevalence of DVS narrowing in the general population to allow for comparison. Data were analyzed using Exact binomial test., Results: Analysis of 25 patients with appropriate imaging revealed the majority were women (21/25, 84%) with a mean age of 51.89 years (SD 13.96). The majority of these patients were found to have narrowing of the DVS (20/25, 80%). In patient with sCSF leaks, there was a significantly higher proportion of patients with DVS narrowing compared with published literature examining this condition in the general population (80% vs. 40%, CI 0.59-0.93, p  < .001)., Conclusion: The prevalence of DVS narrowing in patients with sCSF leaks is substantial and likely greater than the general population. Moreover, there appears to be narrowing in most patients with sCSF leak. Preoperative radiological evaluation of the DVS using MR venography may be useful in patients with sCSF leaks as DVS stenosis may be an underdiagnosed etiology. Further study is needed to evaluate this., Level of Evidence: IV., Competing Interests: William C. Yao serves as a consultant for Aerin Medical and on the speaker's bureau for Optinose Inc. Martin J.

Background: More than a decade after its introduction, some rhinologic surgeons have incorporated the technique of balloon sinus dilation (BSD) technology into "hybrid" endoscopic sinus surgery (ESS) procedures. A novel BSD device which can be placed over standard surgical instruments, including surgical navigation instruments, has recently been introduced. We present a case series in which this device was used as a hydraulic dissection tool to aid safe efficient surgery in difficult-to-access locations of the paranasal sinuses during hybrid ESS procedures., Objective: Highlight the potential role of hydraulic dissection techniques during ESS utilizing BSD., Methods: Retrospective case series of patients who underwent ESS performed in part with a novel BSD device., Results: A total of 10 patients who underwent hybrid ESS with BSD were reviewed. In all 10 cases, the novel BSD device was used without complication. The device was used over straight and curved suctions while being tracked with surgical navigation in all cases. Thirteen posterior ethmoid dissections, 12 sphenoidotomies, and 8 frontal sinusotomies were assisted with the device. For the selected dissections in which the balloon was utilized, the operating surgeon found it to be helpful in creating more space in difficult to access areas which allowed for continued safe surgical dissection., Conclusions: Sinus balloon devices can be used as a hydraulic dissection tool and may be a useful adjunct during ESS. The novel dilation system used in this study, which deploys a sinus balloon device over standard surgical instruments with surgical navigation, provides even more opportunity to accurately dissect difficult areas of the paranasal sinuses safely and efficiently. Further studies evaluating the exact role of sinus balloon devices used as a hydraulic dissection tool during ESS are warranted., Level of Evidence: 4., (© 2021 The Authors.

Objective: Thyroid orbitopathy is a poorly understood extrathyroidal manifestation of Graves' disease that can cause disfiguring proptosis and vision loss. Orbital decompression surgery for Graves' orbitopathy (GO) can address both cosmetic and visual sequelae of this autoimmune condition. Endonasal endoscopic orbital decompression provides unmatched visualization and access to inferomedial orbital wall and orbital apex. This review examines the state of the art approaches employed in endonasal endoscopic orbital decompression for GO., Methods: Review of literature evaluating novel surgical maneuvers for GO., Results: Studies examining the efficacy of endonasal endoscopic orbital decompression are heterogenous and retrospective in design; however, they reveal this approach to be a safe and effective technique in the management of GO., Conclusion: Subtle variations in endoscopic techniques significantly affect postsurgical outcomes and can be tailored to the specific clinical indication in GO making endonasal endoscopic decompression the most versatile approach available., Level of Evidence: NA.
