RESUMEN
Granuloma faciale is an eosinophilic dermatosis that typically presents as red-brown facial plaques of middle-aged white men, while eosinophilic angiocentric fibrosis is a histologically similar fibrotic condition affecting the respiratory mucosa. Both are very uncommon conditions and pose a therapeutic challenge. While a handful of reports have reported concurrent presentation, the authors present the first case of eyelid granuloma faciale with eosinophlilic angiocentric fibrosis.

Allergy and asthma prevalence vary across different subsets of chronic rhinosinusitis with nasal polyposis. In this article, the authors investigate the management of allergy and asthma within populations of patients with aspirin-exacerbated respiratory disease, allergic fungal rhinosinusitis, and central compartment atopic disease. Topical steroids, nasal rinses, and endoscopic sinus surgery are frequently employed in the management of nasal polyposis. Further, other causes of upper and lower airway inflammation like allergy and asthma should be considered in the overall treatment plan in order to optimize outcomes.

BACKGROUND: Endoscopic endonasal surgical resection is an effective therapeutic approach for olfactory neuroblastoma (ONB). Unilateral excision of ONBs with limited extension has been reported with the purpose of preserving olfactory function. We aimed to review implications of surgical management, olfactory preservation feasibility, and survival outcomes in patients who underwent endoscopic unilateral resection of olfactory neuroblastoma. METHODS: A systematic literature review was conducted using the search terms [("Olfactory neuroblastoma") OR ("Esthesioneuroblastoma")] AND [("Unilateral resection") OR ("Olfaction preservation")]. Studies reporting cases of unilateral olfactory neuroblastoma endoscopic resection with postoperative olfaction assessment were included. Concurrently, records of patients who met inclusion criteria at our institution were reviewed retrospectively. The survival and olfactory outcomes were analyzed in both cohorts. RESULTS: Thirty-three patients were identified in the published literature. Twenty-three (69.7%) reported postoperative olfaction preservation. Olfactory function after surgery did not show an association with Kadish stage (p=0.128). No evidence of disease was observed at the latest follow-up in this group of patients. Nine patients who met inclusion criteria were identified at our institution. The extent of resection influenced the level of olfaction preservation when cribriform plate and nasal septum resection coexisted (p=0.05). A single patient at our institution developed recurrence after being lost to follow-up for 22 months. CONCLUSIONS: Olfaction preservation can be achieved in patients who undergo endoscopic unilateral resection and adjuvant radiotherapy. The extent of resection should aim for negative margins, particularly in the midline. Larger studies are required to assess the risk of contralateral microscopic disease, and, hence, close follow-up is advised.
RESUMEN
BACKGROUND: Sinonasal neoplasms, whether benign and malignant, pose a significant challenge to clinicians and represent a model area for multidisciplinary collaboration in order to optimize patient care. The International Consensus Statement on Allergy and Rhinology: Sinonasal Tumors (ICSNT) aims to summarize the best available evidence and presents 48 thematic and histopathology-based topics spanning the field. METHODS: In accordance with prior International Consensus Statement on Allergy and Rhinology documents, ICSNT assigned each topic as an Evidence-Based Review with Recommendations, Evidence-Based Review, and Literature Review based on the level of evidence. An international group of multidisciplinary author teams were assembled for the topic reviews using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses format, and completed sections underwent a thorough and iterative consensus-building process. The final document underwent rigorous synthesis and review prior to publication. RESULTS: The ICSNT document consists of four major sections: general principles, benign neoplasms and lesions, malignant neoplasms, and quality of life and surveillance. It covers 48 conceptual and/or histopathology-based topics relevant to sinonasal neoplasms and masses. Topics with a high level of evidence provided specific recommendations, while other areas summarized the current state of evidence. A final section highlights research opportunities and future directions, contributing to advancing knowledge and community intervention. CONCLUSION: As an embodiment of the multidisciplinary and collaborative model of care in sinonasal neoplasms and masses, ICSNT was designed as a comprehensive, international, and multidisciplinary collaborative endeavor. Its primary objective is to summarize the existing evidence in the field of sinonasal neoplasms and masses.

BACKGROUND: Internal carotid artery injury (ICAI) represents one of the most challenging complications in endoscopic endonasal neurosurgery and its rarity results in limited opportunities for trainees and surgeons to achieve proficiency in its management. Currently, available models for ICAI have employed costly systems that prevent their widespread use. The objective of this study is to validate an affordable submersible peristaltic pump (SPP)-based model as a reproducible and realistic paradigm for ICAI management training. METHODS: A laceration of the left parasellar internal carotid artery was purposely carried out in 2 human cadaveric heads. A blood substitute was perfused to ensure a perfusion flow of 1 L/min using an affordable SPP. A cohort of 20 neurosurgery and otolaryngology residents, fellows, and attendings were enrolled to evaluate the realism and content validity of the model using a validated 5-grade questionnaire. RESULTS: The model proved to mimic a real intraoperative scenario of ICAI with an expected output flow of 1 L/min. Questionnaire responses reported a realistic experience and the impact of this model on improving trainee surgical coordination and capability to rehearse the most accepted repair technique. The use of a fixed noninjected head allowed the reproducibility of the training session without the additional cost of new fresh-frozen heads. The affordable SPP allowed an impactful reduction of ICAI model training expenses maintaining high realism. CONCLUSIONS: The SPP-based ICAI model with noninjected cadaveric specimens is an affordable and cost-effective system that allows reproducibility and realism. These qualities favor greater adoption in neurosurgery and otolaryngology training curricula.

BACKGROUND: Central compartment atopic disease (CCAD) is an emerging phenotype of chronic rhinosinusitis with nasal polyposis (CRSwNP) characterized by prominent central nasal inflammatory changes. This study compares the inflammatory characteristics of CCAD relative to other phenotypes of CRSwNP. METHODS: A cross-sectional analysis of data from a prospective clinical study was performed on patients with CRSwNP who were undergoing endoscopic sinus surgery (ESS). Patients with CCAD, aspirin-exacerbated respiratory disease (AERD), allergic fungal rhinosinusitis (AFRS), and non-typed CRSwNP (CRSwNP NOS) were included and mucus cytokine levels and demographic data were analyzed for each group. Chi-squared/Mann-Whitney U tests and partial least squares discriminant analysis (PLS-DA) were performed for comparison and classification. RESULTS: A total of 253 patients were analyzed (CRSwNP, n = 137; AFRS, n = 50; AERD, n = 42; CCAD, n = 24). Patients with CCAD were the least likely to have comorbid asthma (p = 0.0004). The incidence of allergic rhinitis in CCAD patients did not vary significantly compared to patients with AFRS and AERD, but was higher compared to patients with CRSwNP NOS (p = 0.04). On univariate analysis, CCAD was characterized by less inflammatory burden, with reduced levels of interleukin 6 (IL-6), IL-8, interferon gamma (IFN-γ), and eotaxin relative to other groups and significantly lower type 2 cytokines (IL-5, IL-13) relative to both AERD and AFRS. These findings were supported by multivariate PLS-DA, which clustered CCAD patients into a relatively homogenous low-inflammatory cytokine profile. CONCLUSIONS: CCAD has unique endotypic features compared to other patients with CRSwNP. The lower inflammatory burden may be reflective of a less severe variant of CRSwNP.

BACKGROUND: In the 5 years that have passed since the publication of the 2018 International Consensus Statement on Allergy and Rhinology: Allergic Rhinitis (ICAR-Allergic Rhinitis 2018), the literature has expanded substantially. The ICAR-Allergic Rhinitis 2023 update presents 144 individual topics on allergic rhinitis (AR), expanded by over 40 topics from the 2018 document. Originally presented topics from 2018 have also been reviewed and updated. The executive summary highlights key evidence-based findings and recommendation from the full document. METHODS: ICAR-Allergic Rhinitis 2023 employed established evidence-based review with recommendation (EBRR) methodology to individually evaluate each topic. Stepwise iterative peer review and consensus was performed for each topic. The final document was then collated and includes the results of this work. RESULTS: ICAR-Allergic Rhinitis 2023 includes 10 major content areas and 144 individual topics related to AR. For a substantial proportion of topics included, an aggregate grade of evidence is presented, which is determined by collating the levels of evidence for each available study identified in the literature. For topics in which a diagnostic or therapeutic intervention is considered, a recommendation summary is presented, which considers the aggregate grade of evidence, benefit, harm, and cost. CONCLUSION: The ICAR-Allergic Rhinitis 2023 update provides a comprehensive evaluation of AR and the currently available evidence. It is this evidence that contributes to our current knowledge base and recommendations for patient evaluation and treatment.

Patients will continue to present to the otolaryngologist's office with "sinus headaches" as their primary complaint. Otolaryngologists should take particular care in establishing a precise diagnosis. A thorough clinical history, comprehensive head and neck examination, well-performed nasal endoscopy, and imaging as necessary are essential components for effective diagnosis and treatment plan implementation. It is fundamental to acknowledge the criteria for diagnosing the various headache disorders that may disguise themselves as sinonasal complaints. Moreover, this patient population accurately diagnosed and treated will be extremely grateful for someone pointing them in a direction to obtain the relief they truly need.

OBJECTIVE: To compare systemic allergen sensitivity and local allergen sensitivity in the sinonasal tissue of patients with a recently identified subtype of chronic rhinosinusitis strongly associated with allergy: central compartment atopic disease (CCAD). STUDY DESIGN: Prospective cohort study. SETTING: Academic tertiary care rhinology clinic. METHODS: Fifteen participants with endoscopic and radiographic evidence of CCAD underwent systemic allergy testing with skin testing and measurement of serum specific immunoglobulin E (sIgE) to 15 regionally common aeroallergens. Local allergen sensitivity was determined by measuring sIgE to these same 15 allergens in their sinonasal tissue. sIgE testing was performed by ImmunoCAP assay. RESULTS: Of the 15 participants, 14 were sensitive to at least 1 allergen locally in the central compartment and systemically on skin or serum testing. Among all participants, 4 were sensitive to allergens on central compartment sIgE testing that they were not sensitive to on skin and serum sIgE testing (range, 1-8 discordant allergens). Comparisons between local and systemic aeroallergen sensitivity results showed statistically significant correlations (P < .05) ranging from weak to strong. CONCLUSION: Systemic allergy testing is recommended in the initial workup for CCAD. Local allergen sensitivities may be present in a subset of patients with CCAD. Further study of the clinical significance of these sensitivities should be undertaken in CCAD, with evaluation of the role of medical therapies and allergen immunotherapy in the treatment of CCAD.

BACKGROUND: The current classification system of invasive fungal sinusitis (IFS) includes acute (aIFS) and chronic (cIFS) phenotypes. Both phenotypes display histopathologic evidence of tissue necrosis, but differ by presence of angioinvasion, extent of necrosis, and disease progression. aIFS is defined by a rapid onset of symptoms, while cIFS slowly progresses over ≥12 weeks. However, a subset of IFS patients do not fit into the clinical presentation and histopathologic characteristics of either aIFS or cIFS. OBJECTIVES: To investigate the demographic, clinical, and histopathologic characteristics of a distinct subset of IFS. METHODS: Retrospective review of patients with IFS from a single tertiary-care institution (2010-2020). Patients with symptoms for ≤4 weeks were classified as aIFS if they displayed endoscopic evidence of mucosal necrosis or fungal angioinvasion on pathology. Patients with slowly progressive IFS for ≥12 weeks were classified as cIFS. Patients with symptom duration between 4 and 12 weeks with evidence of invasive fungal disease were classified as a new entity and were further investigated. RESULTS: Of the 8 patients identified, 50% were immunosuppressed at presentation. The mean symptom duration prior to presentation was 50.5 days (SD 16.8), and common symptoms included facial pain (100%), vision change (87.5%), and blindness (37.5%). Two patients (25%) died of their disease. Sites of fungal involvement confirmed by histopathology included sphenoid (62.5%) and ethmoid sinuses (12.5%), orbital apex (25%), optic nerve (12.5%), pterygopalatine fossa (12.5%), and clivus (12.5%). Fungal elements but without obvious angioinvasion, were identified in all specimens, and fungus balls (50%), granulomas (37.5%), and giant cells (25%) were also observed on histopathology. CT and MRI radiographic imaging showed findings consistent with orbital, intracranial, or skull base involvement in all patients. CONCLUSION: We propose intermediate IFS as a new subgroup of patients with IFS who do not fit into the standard classification of aIFS or cIFS.

OBJECTIVE: Provide a detailed anatomical description of the olfactory filaments (OF) and their distribution in the nasal cavity through endoscopic endonasal dissection. METHODS: Four cadaveric specimens (8 sides) were used in this study. Nasoseptal (NSM), middle (MTM) and superior turbinate (STM) mucosa dissection was performed to identify the OF and follow them superiorly to the cribriform plate (CP). Measurements of the OF were taken on the NSM, MTM, STM under direct endoscopic visualization. A Student's T-Test was performed to compare means. RESULTS: The NSM contained a mean of 11 OF, distributed over surface area (SA) of 173 ± 31 mm2 with the highest density of OF being found at the posterior NSM. The MTM contained a mean 6 OF, covering a mean SA of 77 mm2, with the first OF found 5 mm from the anterior border of the MTM, on average. The STM had a mean 9 OF, with the OF covering a mean SA of 96 mm2. Overall mean OF length was 6 mm. The STM OF were significantly greater in number, with a greater distance from the first OF to last OF (p < 0.05) than the MTM OF. SUMMARY: The STM and MTM combined were found to have a greater density of OF than the NSM. The STM contains a significantly greater number of OF covering a greater area than the MTM OF. Preservation of the STM and MTM in skull base defect repair, and in routine sinus surgery, can be as beneficial for olfactory function as preservation of the NSM; particularly in CP defect repair. Moreover, our findings indicate that nasoseptal flap harvest performed at least 6 mm from the skull base preserves OF in the NSM. To our knowledge, this is the first anatomical study of the OF through direct endoscopic observation and measurements.

BACKGROUND: Central compartment atopic disease (CCAD) is a variant of chronic rhinosinusitis (CRS) with nasal polyps (CRSwNP) characterized by polypoid changes of the superior nasal septum, middle (MT), and/or superior turbinates (ST). This study evaluates surgical outcomes in patients with CCAD compared with other CRSwNP subtypes. METHODS: Retrospective analysis was performed at Emory University from May 2012 to November 2019. Patients undergoing primary endoscopic sinus surgery (ESS) for CCAD, aspirin-exacerbated respiratory disease (AERD), allergic fungal rhinosinusitis (AFRS), and CRSwNP not otherwise specified (CRSwNP NOS) were included consecutively, beginning with the earliest date of CCAD patient. Outcome measures included polyp recurrence, revision ESS, oral steroid use, and oral antibiotic use. Pearson chi-square and univariate analysis of variance (ANOVA) were performed for group comparisons. RESULTS: Data was collected for 132 patients (CCAD = 38, AERD = 20, AFRS = 37, CRSwNP NOS = 37; 58 females, mean age 42.9 years [range, 13-85 years]). CCAD patients demonstrated polyp recurrence less frequently than expected, whereas AFRS patients had polyp recurrence more frequently than expected (p = 0.003; phi 0.32). CCAD patients underwent revision ESS less frequently than expected; AFRS and CRSwNP NOS underwent revision ESS more frequently than expected (p = 0.03; phi 0.26). CRSwNP NOS patients received more total antibiotic courses than those with CCAD (p = 0.01; eta-squared 0.09) and more courses of antibiotics per month than those with AFRS (p = 0.03; eta-squared 0.07). There was no significant difference in follow-up measures across groups (number of visits, total months, or visits per month). CONCLUSION: Rates of polyp recurrence and revision ESS were significantly lower in CCAD patients compared with patients with other CRSwNP subtypes, suggesting durable benefit of ESS and postoperative medical therapy in CCAD patients.

BACKGROUND: The association between spontaneous skull base cerebrospinal fluid (CSF) leaks and idiopathic intracranial hypertension (IIH) has been suggested, but its significance remains unclear. OBJECTIVE: To estimate the prevalence of IIH in spontaneous skull base CSF leak patients. METHODS: Systematic collection of demographics, neuro-ophthalmic and magnetic resonance imaging evaluation of spontaneous skull base CSF leak patients seen pre- and post-leak repair in one neuro-ophthalmology service. Patients with preexisting IIH were diagnosed with definite IIH if adequate documentation was provided; otherwise, they were categorized with presumed IIH. Classic radiographic signs of intracranial hypertension and bilateral transverse venous sinus stenosis were recorded. RESULTS: Thirty six patients were included (age [interquartile range]: 50 [45;54] years; 94% women; body mass index: 36.8 [30.5;39.9] kg/m2), among whom six (16.7%, [95% confidence interval, CI]: [6.4;32.8]) had a preexisting diagnosis of definite or presumed IIH. Of the remaining 30 patients, four (13.3%, 95%CI: [3.8;30.7]) had optic nerve head changes suggesting previously undiagnosed IIH, while one was newly diagnosed with definite IIH at initial consultation. One out of 29 patients with normal findings of the optic nerve head at presentation developed new onset papilledema following surgery (3.4%, 95%CI: [0.1;17.8]) and was ultimately diagnosed with definite IIH. Overall, the prevalence of definite IIH was 19.4% (95%CI: [8.2;36.0]). CONCLUSION: Striking demographic overlap exists between IIH patients and those with spontaneous CSF leak. Definite IIH was present in approximately 20% of our patients. However, its true prevalence is likely higher than identified by using classic criteria. We therefore hypothesize that an active CSF leak serves as an auto-diversion for CSF, thereby "treating" the intracranial hypertension and eliminating characteristic signs and symptoms at initial presentation.

Aspergillus is a chronic colonizer as well as a nidus of infection in the sinuses and ears. In the sinuses, the severity of the disease is classified by the invasiveness of the infection. Invasive fungal sinusitis varies in its presentation based upon the infective organism and shows reduced morbidity if identified early, which requires a high index of suspicion. Allergic fungal sinusitis was recently further classified using a radiologic staging system and was proven to have symptomatic improvement with the concomitant use of surgery and immunotherapy. Finally, fungal ball appears to be a chronic problem that is usually cured with surgery. Aspergillus in the ear is a relatively common problem often related to prolonged antibiotic use and almost always successfully treated with topical antifungals.
RESUMEN
OBJECTIVE: Endoscopic sinus surgery is the gold standard for the treatment of medically refractory chronic rhinosinusitis. There is, however, a population of patients for whom persistent disease is a problem. Of all the sinuses, the frontal sinus is the most likely to have recurrent obstruction. We evaluated the findings causing frontal recess obstruction at the time of revision surgery. STUDY DESIGN AND SETTING: A retrospective review was performed in a tertiary care academic otolaryngology department. RESULTS: Findings obstructing the frontal recess at the time of revision sinus surgery were reviewed. Two hundred eighty-nine frontal sinuses were included. Seven findings were identified: mucosal disease (67%), retained ethmoid cells (53%), lateralized middle turbinates (30%), retained agger nasi cells (13%), scar (12%), retained frontal cells (8%), and neoosteogenesis (7%). Most frontal recesses had multiple etiologies for failure listed above, with an average of 1.6. CONCLUSIONS: Multiple findings can be identified that contribute to frontal recess obstruction requiring revision sinus surgery. A comprehensive approach to address all factors is necessary to prevent surgical failure among patients presenting for endoscopic frontal sinus surgery.

BACKGROUND: Pneumocephalus is a rare complication of endoscopic sinus surgery (ESS) and microscopic skull base surgery (MSBS). Postoperatively, patients often present with headache and altered mental status. Unrepaired leaks are associated with an increased risk of ascending meningitis. Standard treatment of pneumocephalus after ESS or MSBS has not been addressed in the literature. METHODS: The study involved a retrospective review of patients at an academic tertiary care center with pneumocephalus after ESS or MSBS. RESULTS: Ten cases of pneumocephalus were identified, 8 after ESS and 2 after MSBS. Seven ESS defects were very small (<3 mm). The remaining three had defects more than 1 cm. Six of the 8 ESS patients had spontaneous resolution of their cerebrospinal fluid (CSF) leak and pneumocephalus, whereas all patients with larger defects failed conservative therapy with lumbar drainage. Lumbar drainage worsened the pneumocephalus in the MSBS patients. Despite resolution of pneumocephalus in many patients, all were recommended to undergo endoscopic exploration due to concern for increased risk of meningitis in unrepaired defects. Endoscopic repair was necessary in 8 cases. Repairs required a mucosal graft with or without a bone graft. Many spontaneously healed defects were found to be very tenuous. In 2 cases, patients were found to have dense scar over the defect not requiring repair. CONCLUSIONS: In patients with pneumocephalus after ESS or MSBS, consideration should be given to endoscopic exploration and repair of the defect with mucosal grafting. Even if spontaneous resolution has occurred, there may be increased risk of ascending meningitis through the thin or incompletely regenerated mucosa.

OBJECTIVE: Intracranial complications of sinusitis (ICS) are uncommon in the antibiotic era. The role of neurosurgical drainage of ICS is fairly well established, but the role for acute surgical intervention for the sinus disease is not well defined. We retrospectively reviewed our experience with ICS to see if we could identify the role and effectiveness of endoscopic sinus surgery (ESS) in the acute setting of ICS. METHODS: The study used a retrospective review of patients presenting to a tertiary care academic medical center for a 6-year period. RESULTS: Twenty-three patients were identified with ICS, including epidural (8), subdural (10), intracerebral abscesses (2), and meningitis (3). Males were more affected than females (7:1). Twenty patients were 21 years old or younger. Twenty-two patients (96%) had radiologic evidence of frontal sinusitis with prefrontal or frontal lobe ICS at presentation. Medical therapy alone was successful in avoiding craniotomy in only 3 of 8 cases. Endoscopic sinus surgery and intravenous antibiotics as initial treatment was successful in avoiding craniotomy in only 1 of 6 patients. Of 23 patients, 18 underwent neurosurgical procedures--9 emergent procedures for abscesses more than 1 cm and 9 delayed procedures for persistent disease despite ICS less than 1 cm at presentation. CONCLUSIONS: Intracranial complications of sinusitis usually result from indirect spread of acute frontal sinusitis. The role of ESS in the initial treatment of ICS is not clear. In our series, ESS did not appear to alter the need for neurosurgical intervention, which was ultimately necessary in most patients with ICS, even with lesions less than 1 cm.

OBJECTIVE: Imaging findings play an important role in the workup and diagnosis of sinonasal disease. Unilateral versus bilateral involvement is a key finding that can differentiate between various diagnoses. Our objective is to characterize presenting symptoms, imaging findings, and most common diagnoses associated with unilateral versus bilateral sinonasal disease. METHODS: Patients who underwent surgical intervention for sinonasal disease at Emory University between May 2015 and December 2016 were included in the study. Information including demographic variables, comorbidities, presenting symptoms, imaging findings, and pathologic diagnosis was collected for each patient. Unilateral versus bilateral disease was determined by preoperative computer tomography and magnetic resonance imaging, and correlated to surgical and pathologic findings. Data was analyzed using quantitative methodologies and descriptive statistics. RESULTS: The study cohort consisted of 250 patients presenting for primary sinonasal surgery, including 110 patients with unilateral disease and 140 patients with bilateral disease. The most common diagnosis for patients with bilateral disease was chronic rhinosinusitis with nasal polyps (46%) followed by chronic rhinosinusitis without polyps (26%). For patients with unilateral disease the most common diagnoses were chronic rhinosinusitis without nasal polyps (21%), malignancy (19%), benign neoplasm (15%), and allergic fungal sinusitis (10%). There was a statistically significant association between unilateral sinonasal disease and the final diagnosis of benign neoplasm (OR = 7.8, P < .01) and malignancy (OR = 8, P < .01). CONCLUSION: Patients with unilateral sinus disease on initial imaging are less likely chronic rhinosinusitis compared to patients with bilateral disease. This should be taken into consideration in the workup and management of patients with unilateral sinus disease. LEVEL OF EVIDENCE: 3 Laryngoscope, 130:E116-E121, 2020.

This literature review collates and summarizes recent literature to explore the relationship between chronic rhinosinusitis (CRS) and allergy. The relationship between CRS and allergy is not fully understood. However, current evidence suggests a relationship between allergy and specific endotypes of CRS with nasal polyposis, including allergic fungal rhinosinusitis and central compartment atopic disease. Specific endotypes of CRS with nasal polyps seem to have an association with allergy. More evidence is necessary to better characterize this relationship. Level of evidence: 5.

BACKGROUND: Respiratory epithelial adenomatoid hamartoma (REAH) is a benign lesion of the sinonasal tract that may mimic more concerning pathology. Clinical factors associated with REAH have not been well characterized. OBJECTIVE: To report our findings on patients with this pathologic diagnosis. METHODS: A retrospective chart review of patients with REAH between September 2006 and November 2019 was conducted. Data collected included clinical allergic rhinitis and asthma history, additional sinonasal diagnoses, prior sinus surgery, and the location of the REAH within the sinonasal cavity. RESULTS: Twenty-six patients were identified (53.8% male, mean age 62 years [range, 29-93]). Bilateral REAH occurred in 50%. REAH was located at the superior nasal septum in 84.6% cases, with the remainder identified in sinus contents submitted for pathology, making definitive site uncertain. Concurrent sinonasal inflammatory disorders were identified in 18 patients (69.2%), including chronic rhinosinusitis with nasal polyps-not otherwise specified (6), chronic rhinosinusitis without nasal polyps (4), aspirin-exacerbated respiratory disease (2), allergic fungal rhinosinusitis (1), central compartment atopic disease (5), and IgG4-related sclerosing disease (1). Eight patients had isolated REAH. Adequate allergy records were available for 19 patients, of which 18 of 19 (94.7%) had clinical allergic rhinitis. CONCLUSIONS: REAH is a benign sinonasal lesion commonly located within the central compartment of the nasal cavity, a site of significant allergen exposure. Affected patients have a high incidence of allergy along with chronic inflammatory conditions. The coexistence of REAH within inflammatory nasal mucosa in a consistent anatomic location, suggests REAH may have a similar etiology to central compartment atopic disease, with resultant respiratory glandular ingrowth within long-standing reactive changes of mucosa derived from ethmoid embryologic origin.
