RESUMEN
OBJECTIVE: Surgical frailty estimates a patient's ability to withstand the physiologic stress of an intervention. There is limited data regarding the impact of frailty on endoscopic cerebrospinal fluid (CSF) leak repair. METHODS: Patients undergoing CSF leak repair at two tertiary academic skull base programs were retrospectively reviewed. Demographic, treatment, and postoperative outcomes data were recorded. Frailty was calculated using validated indices, including the American Society of Anesthesiologists (ASA) classification, Charlson Comorbidity Index (CCI), and the Modified 5-Item Frailty Index (mFI-5). Outcomes included 30-day medical and surgical complications and readmission. RESULTS: A total of 185 patients were included with 128 (69.2%) female patients and average age of 54 ± 14 years. The average body mass index was 34.6 ± 8.5. The most common identified etiology was idiopathic intracranial hypertension (IIH) in 64 patients (34.6%). A total of 125 patients (68%) underwent perioperative lumbar drain placement (primarily to measure intracranial pressures and diagnose IIH). Most patients were ASA class 3 (48.6%) with mean CCI 2.14 ± 2.23 and mFI-5 0.97 ± 0.90. Three patients had postoperative CSF leaks, with an overall repair success rate of 98.4%. There was no association between increased frailty and 30-day medical outcomes, surgical outcomes, or readmission (all p > 0.05). CONCLUSIONS: Endoscopic CSF leak repair in a frail population, including lumbar drain placement and bed rest, was not associated with an increased rate of complications. Previous data suggests increased complications in open craniotomy procedures in patients with significant comorbidities. This study suggests that the endoscopic approach to CSF leak repair is well tolerated in the frail population. LEVEL OF EVIDENCE: IV Laryngoscope, 134:2713-2717, 2024.

OBJECTIVE: Frailty metrics estimate a patient's ability to tolerate physiologic stress and there are limited frailty data in patients undergoing expanded endonasal approaches (EEA) for suprasellar pathologies. Elevated frailty metrics have been associated with increased perioperative complications in patients undergoing craniotomies. We sought to examine this potential relationship in EEA. STUDY DESIGN: Retrospective cohort study. SETTING: Two tertiary academic skull base centers. METHODS: Cases of patients undergoing EEA for suprasellar pathologies were reviewed. Demographic, treatment, survival, and postoperative outcomes data were recorded. Frailty was calculated using validated indexes, including the American Society of Anesthesiologists (ASA) classification, the modified 5-item frailty index (mFI-5), and the Charlson comorbidity index (CCI). Primary outcomes included 30-day medical and surgical complications. RESULTS: A total of 88 patients were included, with 59 (67%) female patients and a mean age of 54 ± 15 years. The most common pathologies included 53 meningiomas (60.2%) and 21 craniopharyngiomas (23.9%). Most patients were ASA class 3 (54.5%) with mean mFI-5 0.82 ± 1.01 and CCI 4.18 ± 2.42. There was no association between increased frailty and 30-day medical or surgical outcomes (including postoperative cerebrospinal fluid leak), prolonged length of hospital stay, or mortality (all P > .05). Higher mFI-5 was associated with an increased risk for 30-day readmission (odds ratio: 2.35, 95% confidence Interval: 1.10-5.64, P = .04). CONCLUSION: Despite the patient population being notably frail, we only identified an increased risk for 30-day readmission and observed no links with deteriorating surgical, medical, or mortality outcomes. This implies that conventional frailty metrics may not effectively align with EEA outcomes.

With the widespread adoption of intranasal radiofrequency (RF) devices, our objective was to report national adverse events (AEs) associated with their use. The Food and Drug Administration's Manufacturer and User Facility Device Experience was queried. A total of 24 device-related AEs were reported, 11 (45.8%) for Celon® (Olympus), 3 (12.5%) for Vivaer® (Aerin), 2 (8.3%) for Neuromark® (Neurent), and 8 (33.3%) for Rhinaer® (Aerin). Seven (63.6%) of the Celon®-related complications were related to tissue necrosis (largely user error-related), but 1 (9.1%) episode of pediatric ocular palsy was also reported. Vivaer® complications included synechiae formation, a mucosal perforation, and a case of empty nose syndrome. Of the posterior nasal nerve ablating devices, 9 of 10 AEs were epistaxes, of which 7 (77.8%) required operative intervention. Surgeons should exercise vigilance and tissue-appropriate device settings when utilizing RF devices. Epistaxis and tissue necrosis may occur, as well as more rare, but devastating, complications.

OBJECTIVE: Nasal airway obstruction (NAO) is caused by various disorders including nasal valve collapse (NVC). A bipolar radiofrequency (RF) device (VivAer®, Aerin Medical, Sunnyvale, CA) has been used to treat NAO through RF heat generation to the upper lateral cartilage (ULC). The purpose of this study is to measure temperature elevations in nasal tissue, using infrared (IR) radiometry to map the spatial and temporal evolution of temperature. STUDY DESIGN: Experimental and computational. METHODS: Composite porcine nasal septum was harvested and sectioned (1 mm and 2 mm). The device was used to heat the cartilage in composite porcine septum. An IR camera (FLIR® ExaminIR, Teledyne, Wilsonville, OR) was used to image temperature on the back surface of the specimen. These data were incorporated into a heat transfer finite element model that also calculated tissue damage using Arrhenius rate process. RESULTS: IR temperature imaging showed peak back surface temperatures of 49.57°C and 42.21°C in 1 and 2 mm thick septums respectively. Temperature maps were generated demonstrating the temporal and spatial evolution of temperature. A finite element model generated temperature profiles with respect to time and depth. Rate process models using Arrhenius coefficients showed 30% chondrocyte death at 1 mm depth after 18 s of RF treatment. CONCLUSION: The use of this device creates a thermal profile that may result in thermal injury to cartilage. Computational modeling suggests chondrocyte death extending as deep as 1.4 mm below the treatment surface. Further studies should be performed to improve dosimetry and optimize the heating process to reduce potential injury. Laryngoscope, 134:1063-1070, 2024.

OBJECTIVES: To evaluate the impact of facility volume on outcomes following primary endoscopic surgical management of sinonasal squamous cell carcinoma (SNSCC). METHODS: The 2010-2016 National Cancer DataBase (NCDB) was queried for patients diagnosed with T1-T4a SNSCC surgically treated endoscopically as the primary treatment modality. Factors associated with overall survival (OS) were evaluated, including facility volume. RESULTS: A total of 330 patients who underwent endoscopic surgical management of SNSCC were treated at 356 unique facilities designated as either low-volume (LVC; treating 1-2 cases; 0-75th percentile), intermediate-volume centers (IVC; 3-4 cases total; 75th-90th percentile), or 144 high-volume (HVC; treating 5+ cases total; >90th percentile) centers. HVC treated patients with higher T staging (42.1 % vs. 29.8 %) and tumors in the maxillary sinus (26.9 % vs. 13.2 %) and ethmoid sinus (10.3 % vs. ≤8.3 %), while LVCs treated lower T stage tumors (70.2 % vs. 57.9 %) and tumors that were located in the nasal cavity (70.2-78.5 % vs. 62.8 %). On multivariable analysis, factors associated with decreased OS included higher T stage (T3/T4a vs. T1/T2; OR 1.92, 95 % CI 1.06-3.47) and older age (>65 vs. <65; OR 2.69, 95 % CI 1.62-4.49). Cases treated at high-volume centers were not associated with a higher likelihood of OS when compared to low-volume centers (OR 0.70, 95 % CI 0.36-1.35). CONCLUSIONS: HVC are treating more primary tumors of the maxillary and ethmoid sinuses and tumors with higher T stages with endoscopic approaches, although this does not appear to be associated with increased OS. SHORT SUMMARY: Sinonasal squamous cell carcinoma (SNSCC) presents late in disease process with poor prognosis. We investigated the impact of facility volume on outcomes following endoscopic treatment of SNSCC. High-volume centers treat more advanced and complex disease with comparable OS.

BACKGROUND: Sinonasal lymphoma (SL) is a heterogeneous, underrecognized neoplastic disorder with limited outcomes data. We sought to better define outcomes by subtype and treatment at 2 referral centers over the past 2 decades. METHODS: Demographics, clinicopathologic data, and treatment outcomes for patients treated for SL were queried from January 1, 2000 to December 31, 2021 at 2 tertiary academic medical centers. RESULTS: Eighty-four patients were included, with an average age at diagnosis of 63.4 ± 15 years. There were 34 females (40.5%). The majority of patients had an Eastern Cooperative Oncology Group (ECOG) score of <2 (76.2%) and the most common presenting symptom was facial swelling/pain (26.2%). The most common primary site was the nasal cavity (36.9%). Diffuse large B-cell lymphoma was the most common subtype (46.4%), followed by extranodal NK/T-cell lymphoma (17.9%). Chemotherapy was the most common treatment strategy (n = 59, 70.2%), followed by radiation therapy (n = 35, 41.7%) and immunotherapy (n = 24, 28.6%). Disease-specific survival rates at 1, 5, and 10 years were 85.7%, 73.6%, and 58.6%, respectively. Eighteen patients (21.4%) developed recurrence. On multivariate analysis, higher ECOG score (p < 0.0001) and history of head and neck radiation (p = 0.048) were associated with worse survival. Younger age was associated with greater risk of recurrence (p = 0.022) and male sex was associated with more treatment side effects (p = 0.012). CONCLUSION: This is the largest multi-institutional analysis of SL characteristics and outcomes. Our work suggests that, although disease control in the first 5 years is reasonable, 10-year outcomes remain challenging. Further studies are needed to investigate new treatment paradigms and risk stratification.

INTRODUCTION: Surfing is a popular pastime in coastal areas around the world with increasing numbers of participants. There is a lack of detailed data in the literature regarding surfing-related head and neck (HN) injuries. MATERIALS AND METHODS: We queried the National Electronic Injury Surveillance System (NEISS) database to characterize patient demographics, injury types, injury subsite, and emergency department (ED) disposition status associated with surfing-related HN injuries between 2009 and 2020 in the United States. RESULTS: A total of 54,978 estimated national cases were reported from 2009 to 2020. Injuries to the head (36.0%) and neck (35.8%) were most common. Young adults (ages 18-35) made up most ED visits, whereas older adults (>35) made up most (63.5%) admissions. Laceration (46.1%) was the most common injury among ED visits, whereas fracture (30.5%) and internal injury (29.2%) were most common in admitted patients. Concussions represented 7.5% of injuries overall, 9.1% of pediatric injuries, and 9.9% of young adult injuries. CONCLUSIONS: When treating a patient who presents with injury suffered during surfing, a thorough examination of the HN should be performed. Specific attention should be given to evaluation of lacerations, fractures, internal ear injuries, and concussions. Pediatric and young adult patients are at increased risk of concussion. The majority of surfing injuries can be treated in an outpatient context.

Importance: Data regarding outcomes after major head and neck ablation and reconstruction in the growing geriatric population (specifically ≥80 years of age) are limited. Such information would be extremely valuable in preoperative discussions with elderly patients about their surgical risks and expected functional outcomes. Objectives: To identify patient and surgical factors associated with 30-day postoperative complications, 90-day mortality, and 90-day functional decline; to explore whether an association exists between the type of reconstructive procedure and outcome; and to create a preoperative risk stratification system for these outcomes. Design, Setting, and Participants: This retrospective, multi-institutional cohort study included patients 80 years or older undergoing pedicle or free-flap reconstruction after an ablative head and neck surgery from January 1, 2015, to December 31, 2017, at 17 academic centers. Data were analyzed from February 1 through April 20, 2019. Main Outcomes and Measures: Thirty-day serious complication rate, 90-day mortality, and 90-day decline in functional status. Preoperative comorbidity and frailty were assessed using the American Society of Anesthesiologists classification, Adult Comorbidity Evaluation-27 score, and Modified Frailty Index. Multivariable clustered logistic regressions were performed. Conjunctive consolidation was used to create a risk stratification system. Results: Among 376 patients included in the analysis (253 [67.3%] men), 281 (74.7%) underwent free-flap reconstruction. The median age was 83 years (range, 80-98 years). A total of 193 patients (51.3%) had 30-day serious complications, 30 (8.0%) died within 90 days, and 36 of those not dependent at baseline declined to dependent status (11.0%). Type of flap (free vs pedicle, bone vs no bone) was not associated with these outcomes. Variables associated with worse outcomes were age of at least 85 years (odds ratio [OR] for 90-day mortality, 1.19 [95% CI 1.14-1.26]), moderate or severe comorbidities (OR for 30-day complications, 1.80 [95% CI, 1.34-2.41]; OR for 90-day mortality, 3.33 [95% CI, 1.29-8.60]), body mass index (BMI) of less than 25 (OR for 30-day complications, 0.95 [95% CI, 0.91-0.99]), high frailty (OR for 30-day complications, 1.72 [95% CI, 1.10-2.67]), duration of surgery (OR for 90-day functional decline, 2.94 [95% CI, 1.81-4.79]), flap failure (OR for 90-day mortality, 3.56 [95% CI, 1.47-8.62]), additional operations (OR for 30-day complications, 5.40 [95% CI, 3.09-9.43]; OR for 90-day functional decline, 2.94 [95% CI, 1.81-4.79]), and surgery of the maxilla, oral cavity, or oropharynx (OR for 90-day functional decline, 2.51 [95% CI, 1.30-4.85]). Age, BMI, comorbidity, and frailty were consolidated into a novel 3-tier risk classification system. Conclusions and Relevance: Important demographic, clinical, and surgical characteristics were found to be associated with postoperative complications, mortality, and functional decline in patients 80 years or older undergoing major head and neck surgery. Free flap and bony reconstruction were not independently associated with worse outcomes. A novel risk stratification system is presented.
