Relationship between pain-related comorbidities and quality of life in patients with symptoms of chronic rhinosinusitis.

INTRODUCTION: Facial pain is a common manifestation of sinonasal disease but may be due to a variety of other conditions. Misattribution of pain to chronic rhinosinusitis may result in worse quality of life in populations both with and without objective evidence of sinonasal disease. The purpose of this study was to determine if there is an association between pain-related comorbidities and worse chronic rhinosinusitis specific quality of life in patients with and without objective evidence of sinonasal inflammation. METHODS: Retrospective cohort study of 299 patients meeting diagnostic criteria for sinusitis evaluated at a tertiary academic medical center from 2017 to 2018. Objective evidence was measured using the Lund-Kennedy and Lund-MacKay scoring systems; for the purposes of this study a score >3 on either scale was considered indicative of disease. Quality of life was determined by the rhinosinusitis disability index. RESULTS: A total of 191 patients were included in the study, with an average age of 52.7. (SD=15.3). The average Lund-Kennedy and Lund-MacKay scores were 4.7 and 8.3, respectively. The average rhinosinusitis disability index was 32.1. When stratified by the presence of pain-related comorbidities, there was no significant difference in Lund-Kennedy (p = 0.203), Lund-MacKay (p = 0.101), or rhinosinusitis disability index (p = 0.421). CONCLUSION: Although prior studies have suggested a correlation between the presence of pain-related comorbidities and worse chronic rhinosinusitis specific quality of life, this relationship was not evident within the current cohort of patients. The relationship between pain and sinusitis specific quality of life is likely complex and requires further research to fully elucidate.

Subcutaneous emphysema after vigorous sneezing in the setting of acute frontal sinusitis.

INTRODUCTION: Subcutaneous emphysema [SCE] can develop due to traumatic, infectious, and spontaneous causes and usually localizes to the periorbital space. CASE: We present a case of an 18-year-old male with an 8-day history of migraine-like headaches followed by the acute onset of frontofacial swelling after vigorous sneezing. Radiologic and physical exam findings supported a diagnosis of frontofacial SCE in the setting of frontal sinusitis. DISCUSSION: A sneeze, although usually benign, causes a significant increase in intranasal pressure. When coupled with a history significant for facial trauma or rhinosinusitis, this rise in pressure can be sufficient to cause fracturing of the bone overlying a paranasal sinus, leading to the formation of SCE.

Impact of elexacaftor/tezacaftor/ivacaftor CFTR modulator therapy on rates of endoscopic sinus surgery in cystic fibrosis.

BACKGROUND: Elexacaftor/tezacaftor/ivacaftor (ETI), a combination cystic fibrosis transmembrane receptor (CFTR) modulator, has demonstrated improved pulmonary outcomes in individuals with cystic fibrosis (CF). However, ETI's impact on functional endoscopic sinus surgery (FESS) remains unclear. METHODS: The TriNetX Analytics Research Network, consisting of 120 million global de-identified electronic medical records, was queried from 2012 to 2023 for subjects with CF who underwent sinus surgery.1 Patients on ETI prior to FESS (n = 6,056) were propensity score matched to control individuals with CF not on CFTR modulators (n = 37,906) and those on other FDA-approved CFTR modulators (tezacaftor/ivacaftor, lumacaftor/ivacaftor, and ivacaftor) (n = 2437) based on relevant factors. The primary outcome was the absolute risk reduction (ARR) of undergoing FESS. Secondary outcomes included ARR of CF-related pulmonary exacerbations and hospital admission from 0 to 6, 6 to 12, and 12 to 24 months following FESS. RESULTS: ETI use demonstrated a significant ARR for FESS when compared to CF patients not on CFTR modulators (2.12%; 95% confidence interval [CI] 1.5-2.75; p-value < 0.0001) and those on other CFTR modulators (4.7%; 95% CI 3.54-5.85; p-value < 0.0001). No significant differences occurred in secondary outcomes between ETI and non-CFTR modulator groups, except for reduced CF-related pulmonary exacerbations from 0 to 6 months post-FESS. Additionally, a significant reduction in pulmonary exacerbations was observed at all time points and hospital admissions within 6 months following FESS compared to those using other CFTR modulators. CONCLUSIONS: In a large dataset, CF patients on ETI demonstrated significantly reduced risk of FESS, pulmonary exacerbations, and hospital admission compared to patients not on CFTR modulators or those on other CFTR modulators, suggesting improved sinonasal disease and overall health status in CF.

Treatment of unilateral olfactory neuroblastoma: Appropriate extent of surgical resection and potential for olfactory preservation.

Historically, comprehensive surgical resection for olfactory neuroblastoma has included the bilateral olfactory epithelium, cribriform plate, overlying dura, olfactory bulbs and tracts. This results in postoperative anosmia that may significantly impact a patient's quality of life without definitive added benefit in survival. The prevalence of occult intracranial disease is low, especially for Hyams grade I and II tumors. A unilateral approach sparing the contralateral cribriform plate and olfactory system can be considered for select cases of early stage, low-grade tumors when the disease does not cross midline to involve the contralateral olfactory cleft or septal mucosa and when midline dural margins can be cleared with frozen pathology. Approximately half of patients who undergo unilateral resection may have residual olfaction even with adjuvant unilateral radiation. Early data suggest favorable disease-free survival and overall survival for patients who underwent the unilateral approach; however, larger sample studies are needed to confirm comparability to bilateral resections regarding oncologic outcomes.

Impact of dual electronic and conventional cigarette use on diagnosis and surgery for chronic rhinosinusitis: A multicenter study.

KEY POINTS: Dual EC/CC users had a significantly greater risk of CRS or FESS when compared to solo users. Dual EC/CC users did not have a significantly greater risk of polyposis when compared to solo users. This effect likely relates to bacterial, immune cell, genetic, and mucociliary alterations.

Management of Complications and Secondary Deformity After Fractures of the Midface, Orbit, and Upper Third of the Maxillofacial Skeleton.

Craniomaxillofacial trauma is a challenging entity to manage effectively and often necessitates serial evaluation and treatment. A multidisciplinary team is best served to evaluate and treat these complex injury patterns with the use of necessary adjuncts, such as neuronavigation, intraoperative imaging, custom implant use, and virtual surgical planning. Complications of facial trauma can present at a spectrum of time points and manifest in a variety of manners and as such patients should be observed closely and longitudinally. Although not all complications and secondary deformities can be avoided, this article highlights some common pitfalls and our unique management strategies.

Anatomically realistic nasal replicas capturing the range of nasal spray drug delivery in adults.

To improve the relationships between commonly conducted in vitro studies for locally-acting nasal spray drug products with in vivo regional deposition, this study developed a set of in vitro adult nasal geometries that captured the range of nasal drug delivery to the region posterior to internal nasal valve (INV), also known as posterior delivery (PD), and evaluated their performance with existing in vivo data. The PD of fluticasone propionate (FP) and fluticasone furoate (FF) in 40 nasal cavities was statistically analyzed to identify three airway models representing the low, mean, and high PD in adults. The models were also externally validated by comparing the in vitro nasal deposition from a different drug product (mometasone furoate (MF)) with the relevant in vivo data. The three selected geometries represented the low, mean, and high PD with multiple nasal sprays. They were verified in terms of reproducibility of in vitro data and validated by showing a reasonable agreement with preexisting in vivo MF PD despite differences in administration and defining the regions. The three models are envisioned to potentially facilitate the development of locally-acting nasal sprays and provide a better understanding of how in vitro metrics relate to in vivo regional nasal deposition.

Correlations to Estimate the Key Anatomical Dimensions of Pediatric Nasal Airways using Minimally Invasive Measurements of Intranasal Pressure Gradient.

Background: Understanding the morphology of nasal airways is important in determining the nasal airway deposition of inhaled aerosol. Moreover, objective assessment of the anatomy of human nasal airways is useful to develop a database of reference or normal values as a resource to investigate anatomical abnormalities of airways. Current methods for the objective assessment of the nasal airways are either limited to very few dimensions or can only be performed by specialized researchers. Thus, the main objective of this study was to determine the correlations between the intranasal pressure gradient (Δp) and the key anatomical dimensions of the pediatric nasal airways, which could in turn allow the extrapolation of nasal airway morphology based on simple minimally invasive measurements of pressure. Methods: The anatomical data and Δp were obtained from in vitro studies with nasal airway models of 11 infants ages 3-18 months and 13 children ages 4-14 years old. Key anatomical dimensions were identified based on both rhinology and aerosol dosimetry literature. These anatomic data, including the volume, V, surface area, As, length, L, and the minimum cross-sectional area of the replicas, Amin, were then analyzed for correlation with Δp and flow parameters, using Bernoulli's principle and dimensional analysis. Results: Strong correlations were found between Δp and As/L for children, and between Δp and V/As for infants. Additional pressure gradient correlations were developed with Amin, V/As, V∕L, and L. Conclusions: The correlations identified between anatomic data and Δp have clinical implications in pediatric rhinology, suggesting that certain aspects of airway anatomy in infants and children can be predicted through the measurement of Δp. The airway dimensions, predicted using Δp measurement, may be used in tandem with aerosol nasal deposition correlations that account for nasal airway dimensions.

Sinus Surgery: Analysis of Videos Available Online.

OBJECTIVES: YouTube is the second most visited website in the world and can be a useful resource for patients to gain insight into surgical procedures. A multitude of studies have evaluated the quality of otolaryngology-specific healthcare information available on the YouTube platform, but to our knowledge, the online content regarding functional endoscopic sinus surgery available on this site has not been systematically evaluated. STUDY DESIGN: Cross sectional study. SETTING: Online. METHODS: YouTube was searched using the keywords "sinus surgery." Variables including video length, total number of views, authorship (academic, private practice physician, patient, or third party), objective (advertisement, informative, or patient perspective), inclusion of intra-operative footage, and discussion of balloon sinuplasty were recorded and analyzed by a single reviewer. RESULTS: Two-hundred twenty-two videos met inclusion criteria, with a median length of 4 minutes, and a median of 3349 views. The majority of videos were informative (n = 145, 65%), narrated (n = 151, 68%), and did not mention balloon sinuplasty (n = 189, 85%) nor contain intra-operative footage (n = 116, 52%). Private practice physicians were the most common authors (n = 113, 51%), followed by patients (n = 70, 32%), third parties (n = 28, 13%) and academics (n = 11, 5%). CONCLUSIONS: Sinus surgery is one of the most common ambulatory procedures performed. Online resources such as YouTube can be useful for improving health literacy and patient comfort with medical topics such as functional endoscopic sinus surgery, but it is important for clinicians and patients to understand that there is a spectrum in the authorship, content, and quality of sinus surgery related videos posted online.

Pain Catastrophizing and Quality of Life in Adults With Chronic Rhinosinusitis.

OBJECTIVES/HYPOTHESIS: Psychological comorbidity is common in patients with chronic rhinosinusitis (CRS) and is correlated with decreased overall and disease-specific quality of life (QoL). Prior research reported that anxiety and depression, as measured by the hospital anxiety and depression scale (HADS), are associated with worse CRS-specific QoL, as assessed via the Rhinosinusitis Disability Index (RSDI). Furthermore, patients prone to anxiety/depression may display an exaggerated response to real or anticipated discomfort; the pain catastrophizing scale (PCS) is a validated instrument designed to measure this phenomenon. This study is intended to explore the role of pain catastrophizing in relation to anxiety, depression, and disease-specific QoL in patients with facial pain attributed to CRS. STUDY DESIGN: Prospective cohort study. METHODS: Diagnosis of presumed CRS was based upon current American Academy of Otolaryngology - Head & Neck Surgery (AAO-HNS) guidelines; all participants reported facial pain as a component of their CRS symptomatology. RSDI, HADS, and PCS questionnaires were administered upon presentation prior to intervention, and objective measurements of sinonasal inflammation were obtained via nasal endoscopy and computed tomography (CT). RESULTS: Seventy-five patients were enrolled in the study. Significant positive correlations were found between PCS and HADS, total RSDI, and RSDI emotional sub-scores (P < .05). The incidence of objective evidence of disease, as measured via nasal endoscopy and CT, was not significantly different in catastrophizing patients. CONCLUSIONS: Pain catastrophizing correlates with anxiety/depression and worse disease-specific QoL in patients meeting symptomatic criteria for CRS. Otolaryngologists should be aware that catastrophic thinking can intensify a patient's perception of sinonasal symptoms, and clinicians may consider management of psychological comorbidity to optimize rhinologic outcomes.

The Sensitivity and Specificity of Touch Preparation for Rapid Diagnosis of Invasive Fungal Sinusitis: A Pilot Study.

Invasive fungal sinusitis is a morbid pathology that typically affects immunocompromised patients and may quickly progress to fulminant disease. The purpose of this study was to measure the sensitivity and specificity of touch preparation of nasal debridement specimens as a rapid diagnostic tool for invasive fungal sinusitis. A retrospective chart review was performed of 22 patients undergoing nasal debridement due to suspicion for invasive fungal sinusitis over a 10-year period. Thirteen patients had touch preparation of nasal specimens followed by routine histologic processing; two of these patients underwent 2, and 1 patient had 3 separate debridements, for a total of 17 touch preparations performed. The sensitivity and specificity of touch preparation were calculated by correlating the initial results with the presence of fungal invasion on final pathologic analysis. The sensitivity of touch preparation was 56% (95% confidence interval [CI]: 0.23-0.85), specificity was 100% (95% CI: 0.60-1.00), positive predictive value was 100% (95% CI: 0.46-1.00), and negative predictive value was 67% (95% CI: 0.35-0.89). This procedure may be a useful adjunct in situations requiring rapid diagnosis of invasive fungal sinusitis but should not be used as the sole criteria for determining the need for surgical intervention.

In vitro evaluation of regional nasal drug delivery using multiple anatomical nasal replicas of adult human subjects and two nasal sprays.

Quantifying drug delivery to the site of action using locally-acting nasal suspension sprays is a challenging but important step toward understanding bioequivalence (BE) between test and reference products. The main objective of this study was to investigate the in vitro deposition pattern of two common but different locally-acting nasal suspension sprays using multiple nasal cavities. Twenty anatomically accurate nasal replicas were developed from high-resolution sinonasal computed tomography scans of adults with healthy nasal airways. The airways were segmented into two regions of anterior and posterior to the internal nasal valve. Both sides of the septum were considered separately; hence, 40 nasal cavities were studied. The positioning of the spray nozzle in all 40 cavities was characterized by the head angle, coronal angle, and the insertion depth. Despite using a controlled protocol to minimize the anterior losses, a wide range of variability in posterior drug delivery was observed. The observed intersubject variability using this in vitro method may have important implications for understanding BE of locally-acting nasal suspension sprays.

Use of anatomically-accurate 3-dimensional nasal airway models of adult human subjects in a novel methodology to identify and evaluate the internal nasal valve.

The optimal method for radiographic evaluation of the internal nasal valve (INV) has not been established. The objective of this study was to develop a method to assess the cross-sectional area and the angle of the INV using anatomically-accurate 3D digital nasal airway models. Axial CT images of the paranasal sinuses of twenty adult subjects with healthy nasal airways (50% female and 50% age ≥ 50) were used to create the models. Patients with significant radiographic evidence of sinonasal disease were excluded. A primary cutting plane that passed through the edge of the nasal bone, upper lateral cartilage, and the head of the inferior turbinate was defined in coronal view. This primary coronal cutting plane was then rotated in 5° increments anteriorly while ensuring the anatomic criteria for the INV were still met. The cutting plane resulting in the minimum INV area was identified as the optimal cutting plane and the total cross-sectional area of INV in this plane,198.79 ± 54.57 mm2, was significantly less than the areas obtained using the existing methods for radiographic evaluation of the INV. The angle between the optimal cutting plane and nasal dorsum was 75.00 ± 10.26°, and the corresponding INV angle was 10.77 ± 6.02°.

Herpes oncolytic therapy of salivary gland carcinomas.

Oncolytic herpes simplex viruses (HSV) have demonstrated potent antitumoral effects against a variety of human malignancies in preclinical studies and are in early clinical trials. We explored the activity of an attenuated, replication-competent, oncolytic HSV (NV1023) for the treatment of human salivary gland carcinomas. NV1023 was able to successfully enter into 4 mucoepidermoid carcinoma (H292, H3118, HTB-41, UT-MUC-1) and 2 adenocarcinoma (HSY, HSG) cell lines, as measured by lacZ assays after exposure to 5 viral particles per cell (MOI 5). Viral plaque assays showed variation of viral replication within these cell lines, ranging from a 268-fold increase (H292) to a 3-fold increase (HSG) in viral titer. At MOI 5, all cell lines showed >95% cytotoxicity from NV1023 by Day 7, except for HSY (73%). At MOI 0.1, H3118 and UT-MUC-1 remained highly sensitive to NV1023, both showing >95% cytotoxicity by Day 7. The mucoepidermoid carcinomas were more sensitive to NV1023 at low viral concentrations compared with the adenocarcinomas. Flank tumors of H3118, HTB-41 and HSY in nude mice showed significant tumor volume reductions after a single intratumoral injection of NV1023 (2 x 10(7) plaque-forming units). These data suggest that oncolytic herpes viruses have significant efficacy entering, replicating within, and lysing human salivary gland carcinomas. These promising biologic agents should be further investigated as novel therapy for patients with salivary carcinomas failing conventional treatment.

Long-term management and outcomes after repair of cerebrospinal fluid rhinorrhea related to idiopathic intracranial hypertension.

PURPOSE OF REVIEW: To identify long-term management strategies and outcomes for the treatment of spontaneous cerebrospinal fluid (CSF) rhinorrhea related to idiopathic intracranial hypertension (IIH). RECENT FINDINGS: Adjuvant treatments following surgical repair of spontaneous CSF leaks are aimed at normalizing intracranial pressure (ICP) to minimize the risk of recurrence. IIH is closely linked to obesity, and growing evidence suggests that weight loss, both through conservative and surgical approaches, is effective at addressing the root cause of this disorder. Recent data also support the use of acetazolamide and dural venous sinus stenting as adjuncts for reducing ICP. SUMMARY: Spontaneous CSF rhinorrhea associated with IIH represents a challenging clinical entity, with an increased risk of recurrence compared to CSF leaks because of other causes. Adjunct therapies intended to reduce ICP likely improve outcomes after surgical repair, but further research is necessary to better characterize the effects of these treatment modalities.

Treatment Paradigm for Nasal Airway Obstruction.

Nasal airway obstruction (NAO) is a common otolaryngic complaint with many potential causes, frequently structural or inflammatory in nature. Patients typically have multiple coexisting factors leading to symptoms. Good patient outcomes require careful preoperative evaluation, including nasal endoscopy, to accurately identify sources of obstruction and tailor intervention appropriately. Common structural causes of NAO include inferior turbinate hypertrophy, nasal septal deviation, and narrowing or collapse of the internal or external nasal valves. The internal nasal valve has the narrowest cross-sectional area within the nasal airway and is thus most sensitive to changes in dimension due to anatomic variation or surgical intervention.

Sinonasal epithelial-myoepithelial carcinoma: Report of a novel subsite and review of the literature.

BACKGROUND: Epithelial-myoepithelial carcinoma (EMC) is a rare tumor of the major and minor salivary glands. Sinonasal EMC is extremely uncommon and hitherto not described within the frontal or ethmoid sinuses. OBJECTIVE: To present a novel sinonasal subsite and review the literature regarding sinonasal EMC. METHODS: A case of frontoethmoidal EMC was presented. A medical literature data base was queried from January 1, 1950, to August 8, 2017, for all reports of sinonasal EMC. RESULTS: A 69-year-old man underwent combined open and endoscopic craniofacial resection of a right frontoethmoidal EMC, a previously undescribed primary location for this tumor. A comprehensive review of the literature revealed 13 additional cases of sinonasal EMC. CONCLUSION: EMC is an uncommon neoplasm typically found in the major salivary glands; occurrence in the nose or paranasal sinuses is extremely rare. EMC often follows an indolent clinical course, although, in a minority of cases, particularly in large tumors with nuclear atypia, more aggressive behavior may be observed.

Elimination of pain improves specificity of clinical diagnostic criteria for adult chronic rhinosinusitis.

OBJECTIVE: Determine whether the elimination of pain improves accuracy of clinical diagnostic criteria for adult chronic rhinosinusitis. STUDY DESIGN: Retrospective cohort study. METHODS: History, symptoms, nasal endoscopy, and computed tomography (CT) results were analyzed for 1,186 adults referred to an academic otolaryngology clinic with presumptive diagnosis of chronic rhinosinusitis. Clinical diagnosis was rendered using the 1997 Rhinosinusitis Taskforce (RSTF) Guidelines and a modified version eliminating facial pain, ear pain, dental pain, and headache. RESULTS: Four hundred seventy-nine subjects (40%) met inclusion criteria. Among subjects positive by RSTF guidelines, 45% lacked objective evidence of sinonasal inflammation by CT, 48% by endoscopy, and 34% by either modality. Applying modified RSTF diagnostic criteria, 39% lacked sinonasal inflammation by CT, 38% by endoscopy, and 24% by either modality. Using either abnormal CT or endoscopy as the reference standard, modified diagnostic criteria yielded a statistically significant increase in specificity from 37.1% to 65.1%, with a nonsignificant decrease in sensitivity from 79.2% to 70.3%. Analysis of comorbidities revealed temporomandibular joint disorder, chronic cervical pain, depression/anxiety, and psychiatric medication use to be negatively associated with objective inflammation on CT or endoscopy. CONCLUSION: Clinical diagnostic criteria overestimate the prevalence of chronic rhinosinusitis. Removing facial pain, ear pain, dental pain, and headache increased specificity without a concordant loss in sensitivity. Given the high prevalence of sinusitis, improved clinical diagnostic criteria may assist primary care providers in more accurately predicting the presence of inflammation, thereby reducing inappropriate antibiotic use or delayed referral for evaluation of primary headache syndromes.
