Prostaglandin E Receptor 2 (EP2) Dysregulation in Allergic Fungal Rhinosinusitis Nasal Polyp Epithelium

OBJECTIVES

Allergic fungal rhinosinusitis (AFRS) is an eosinophilic subtype of chronic rhinosinusitis with nasal polyposis (CRSwNP). This study aimed to investigate the transcriptome of AFRS nasal polyp epithelium.

METHODS

Sinonasal epithelial cells were harvested from healthy nasal mucosa and polyp tissue collected from participants undergoing elective sinonasal surgery. Primary epithelial cells were subsequently grown in air/liquid interface and subjected to RNA-seq analysis, RT-qPCR, immunoblotting, and immunostaining.

RESULTS

A total of 19 genes were differentially expressed between healthy and AFRS sample epithelium. The second top candidate gene, ranked by adjusted p-value, was prostaglandin E receptor 2 (PTGER2). The upregulation of PTGER2 was confirmed by RT-qPCR and immunoblot. The presence of the EP2 receptor, encoded by the PTGER2 gene, was confirmed by immunocytochemistry.

CONCLUSION

PTGER2 is a potential novel therapeutic target for AFRS. EP2 dysregulation is associated with aspirin-exacerbated respiratory disease, potentially giving insight into common mechanisms of disease in severe CRSwNP.

Factors Impacting Follow-Up Care in Allergic Fungal Rhinosinusitis

OBJECTIVE

The purpose of this study was to analyze barriers to medical care and follow-up in patients with allergic fungal rhinosinusitis (AFRS).

STUDY DESIGN

Cross-sectional questionnaire-based study with retrospective chart review.

SETTING

Tertiary Medical Center.

METHODS

Subjects with AFRS and chronic rhinosinusitis with nasal polyps (CRSwNP) were prospectively recruited for completion of the Barriers to Care Questionnaire (BCQ) and formal chart review.

RESULTS

Fifty-nine AFRS and 51 CRSwNP patients participated. AFRS patients were more likely to be lost to follow-up within 6 months of surgery (35.6% vs 17.7%, P = 0.04) and no-show at least 1 appointment (20.3% vs 5.9%, P = 0.03) compared to CRSwNP patients. Men with AFRS were more likely to have only a single follow-up visit (37.0% vs 3.1%, P < 0.001) and be lost to follow-up (66.7% vs 9.4%, P < 0.001) than women. There were no significant differences in the BCQ between groups; however, rate of questionnaire completion was lower in the AFRS group than the CRS group (62.7% vs 80.4%, P = 0.042). AFRS patients who did not complete the BCQ were more likely to be male (63.6% vs 35.1%, P = 0.034), lost to follow-up (77.3% vs 10.8%, P < 0.0001), and have a single follow-up visit (40.9% vs 5.4%, P < 0.0001). Younger age was associated with increased likelihood of having a single follow-up visit (odds ratio 1.143, 95% CI 1.022-1.276).

CONCLUSION

Young, male AFRS patients are more frequently lost to follow-up after surgery and less likely to complete questionnaires assessing barriers to care. Further investigation is needed to assess barriers to follow-up in these at-risk groups.

New Developments in Allergic Fungal Rhinosinusitis Pathophysiology and Treatment

BACKGROUND

Allergic fungal rhinosinusitis (AFRS) is an endotype of chronic rhinosinusitis (CRS) with nasal polyps characterized by eosinophilic mucin laden with fungal hyphae entrapped in expanded sinus cavities with an exaggerated hypersensitivity to fungal elements. The last decade has elucidated fungi-driven inflammatory pathways contributing to the pathophysiology of chronic inflammatory respiratory diseases. In addition, novel therapeutic biologic options have become available for CRS over the last several years.

OBJECTIVE

To review the current literature examining AFRS, focusing on recent developments in our understanding of its pathophysiology and implications for treatment options.

METHODS

Review article.

RESULTS

Fungi-driven respiratory inflammation has been linked to fungal proteinases and toxin activity. In addition, AFRS patients demonstrate a local sinonasal immunodeficiency in antimicrobial peptides and hence limited antifungal activity, along with an exaggerated type 2 inflammatory response, highlighting a possible imbalanced type 1, type 2, and type 3 profile. The elucidation of these dysregulated molecular pathways has highlighted novel potential therapeutic targets. As such, the clinical management of AFRS, which once included surgery and extended courses of oral corticosteroids, is transitioning away from long courses of oral corticosteroids to incorporate novel delivery mechanisms of topical therapeutic targets and biologics for recalcitrant disease.

CONCLUSION

AFRS is an endotype of CRS with nasal polyps (CRSwNP) for which the molecular pathways leading to its inflammatory dysfunction are beginning to be illuminated. In addition to affecting treatment options, these understandings may shape necessary changes to diagnostic criteria and the extrapolated effects of environmental changes on AFRS. More critically, a better appreciation of fungi-driven inflammatory pathways may have implications for the understanding of broader CRS inflammation.

Allergic Fungal Rhinosinusitis: The Role and Expectations of Biologics

Allergic fungal rhinosinusitis (AFRS) is a noninvasive subtype of chronic rhinosinusitis with nasal polyps (CRSwNP) that usually develops in immunocompetent atopic individuals and is more common in geographic regions characterized by warm temperatures and high humidity, conducive to higher environmental fungal presence. Allergic fungal rhinosinusitis usually presents with unique computed tomography findings and significant polyp burden, yet patients often report minimal sinus symptoms. Patients with AFRS often have extremely elevated serum total and fungal-specific IgE levels. Treatment almost always requires surgery, in which adjuvant medical therapy is critical to success. However, until recently the choice of adjuvant therapy has consisted primarily of either oral and/or topical steroids. Although oral corticosteroids decrease recurrence after surgery, data for the effectiveness of other adjunctive pharmacologic agents, including topical and oral antifungal agents and immunotherapy, have remained unclear and hence are not recommended in recent guidelines including the International Consensus of Allergy and Rhinology. Three biologics, omalizumab, dupilumab, and mepolizumab, have recently been approved for treating CRSwNP in general, but clinical trials to date with these biologics did not involve AFRS patients. Recently published case reports and smaller prospective studies have shown good efficacy of these biologics on the AFRS subgroup of patients. This article provides an overview of the understanding of the pathophysiology of AFRS, implications of this understanding on the possible role of biologics, and clinical reports on the use of biologics in treating AFRS. Because biologics are indicated for treating CRSwNP, follow up real-world evidence studies are needed for AFRS.

A Multi-Institutional Database Review of Orbital Complications and Survival Outcomes in Adult Patients with Invasive or Non-Invasive Fungal Rhinosinusitis

BACKGROUND

Invasive fungal rhinosinusitis (IFS) with orbital complications has remained a challenging disease over the past few decades. Only a few studies have been conducted to investigate the factors associated with orbital complications in fungal rhinosinusitis (FRS). We aimed to review the characteristics between IFS and non-invasive fungal rhinosinusitis (NIFS) and determine clinical factors associated with orbital complications and overall survival.

METHODS

A multi-institutional database review study was conducted using the Chang Gung Research Database (CGRD) from January 2001 to January 2019. We identified FRS patients using International Classification of Diseases diagnosis codes and SNOMED CT. We categorized patients into IFS and NIFS groups and analyzed the demographic data, underlying diseases, clinical symptoms, laboratory data, image findings, fungal infection status, and survival outcomes.

RESULTS

We included 1624 patients in our study, with 59 IFS patients and 1565 NIFS patients. The history of an organ or hematopoietic cell transplantation had a significant prognostic effect on the survival outcomes, with surgical intervention and high hemoglobin (Hb) and albumin levels recognized as positive predictors. Posterior ethmoid sinus involvement, sphenoid sinus involvement, facial pain, blurred vision, and periorbital swelling were risk factors of orbital complications.

CONCLUSIONS

In NIFS patients, orbital complications were found to be associated with old age, a high WBC count, high blood glucose, and a high CRP level. For the risk factors of orbital complications in IFS patients, posterior ethmoid sinus involvement, sphenoid sinus involvement, facial pain, blurred vision, and periorbital swelling were recognized as predictors. Among IFS patients, a history of organ or hematopoietic cell transplantation was a risk factor for poor survival, while, conversely, surgical intervention and high Hb and albumin levels were related to improved survival. As predictors of orbital complications in IFS patients, posterior ethmoid sinus involvement, sphenoid sinus involvement, facial pain, blurred vision, and periorbital swelling upon the first visit should raise attention, with close monitoring.

Pediatric Allergic Fungal Rhinosinusitis: Does Age Make a Difference?

Background Allergic fungal rhinosinusitis (AFRS) is a hypersensitive response to fungi within the sinus cavity. Children represent a challenging group of patients with sinonasal disorders, as their sinus anatomy is not fully developed. This study aimed to determine the various clinical manifestations and management outcomes in children with AFRS. Methods A retrospective chart review of children who underwent sinus surgery for AFRS at a tertiary healthcare center between 2005 and 2021 was performed. Demographics, clinical manifestations, radiological and laboratory results, treatment regimens, complications, and recurrence rates were collected. Subanalysis was performed based on age at first surgery: group A (<13 years) and group B (≥13 years). Results Overall, 35 children underwent sinus surgery for AFRS during the study period. The mean patient age at the time of surgery was 14 years. Bilaterality was present in 15/35 (42.9%) patients and anosmia in 12/35 (34.3%). Polyps on examination were present in 31/35 (88.6%) patients and proptosis in 8/35 (22.9%). Sub-analysis revealed that group A showed less bilateral disease (11.4%) than group B (31.4%) and a lower Lund-Mackay score (median=11.50 and 17, respectively, p=0.002). Conclusion Age at surgery did not have an impact on the outcome. A high index of suspicion should be exercised when dealing with children with sinonasal symptoms that do not respond to routine treatment and should be investigated for chronic sinusitis.

Bacterial and Fungal Infections Promote the Bone Erosion Progression in Acquired Cholesteatoma Revealed by Metagenomic Next-Generation Sequencing

An acquired cholesteatoma generally occurs as a consequence of otitis media and eustachian tube dysfunction. Patients with acquired cholesteatoma generally present with chronic otorrhea and progressive conductive hearing loss. There are many microbes reportedly associated with acquired cholesteatoma. However, conventional culture-based techniques show a typically low detection rate for various pathogenetic bacteria and fungi. Metagenomic next-generation sequencing (mNGS), an emerging powerful platform offering higher sensitivity and higher throughput for evaluating many samples at once, remains to be studied in acquired cholesteatoma. In this study, 16 consecutive patients from January 2020 to January 2021 at the Second Affiliated Hospital of Zhejiang University School of Medicine (SAHZU) were reviewed. We detected a total of 31 microbial species in patients, mNGS provided a higher detection rate compared to culture (100% vs. 31.25%, p = 0.000034). As the severity of the patient’s pathological condition worsens, the more complex types of microbes were identified. The most commonly detected microbial genus was Aspergillus (9/16, 56.25%), especially in patients suffering from severe bone erosion. In summary, mNGS improves the sensibility to identify pathogens of cholesteatoma patients, and Aspergillus infections increase bone destruction in acquired cholesteatoma.

Allergic Fungal Sinusitis: Ophthalmic Complications Due to the COVID-19 Pandemic and the Potential of Telemedicine

We report a case of a 26-year-old female who initially presented to an outside optometrist with complaints of proptosis and decreased visual acuity. Magnetic resonance imaging (MRI) obtained at that time was concerning for allergic fungal sinusitis. Unfortunately, the patient’s referral to ophthalmology was delayed due to the coronavirus disease 2019 (COVID-19) pandemic. On presentation to ophthalmology one year later, the patient had clinically deteriorated with significant visual and olfactory loss. She underwent emergent endoscopic sinus surgery by otolaryngology with histological analysis of the sinus debris confirming allergic fungal sinusitis. This is a unique case demonstrating the devastating impact that the COVID-19 pandemic had on patient care for an otherwise treatable condition. We propose the utilization of telemedicine networks as a way to prevent similar complications.

Sinonasal Anatomic Variants in Allergic Fungal Rhinosinusitis

BACKGROUND

The pathophysiology of allergic fungal rhinosinusitis (AFRS) is not well understood.

OBJECTIVES

To study the incidence of sinonasal anatomic variants (AVs) in AFRS.

METHODS

Retrospective cohort study. Patients with AFRS presenting to our clinic from 2008 to 2018 were reviewed for laterality of the disease. Patients with unilateral involvement were further studied for AV presence by reviewing their preoperative sinus CT scan at original presentation. Each patient's uninvolved side served as its own control. AVs studied include agger nasi (AN), Haller's cells (HC), concha bullosa (CB) and supraorbital ethmoid cells (SOEC).

RESULTS

A total of 155 patients with AFRS were identified. 30 patients (19.3%) had unilateral disease involvement. Of these, 16 patients had left sided and 14 patients had right sided disease. AV were present in 26 of the 30 AFRS sides (86.7%) and in 21 of the 30 healthy sides (70%), (chi squared = 2.45, p = 0.117). CB were present in 12 of 30 AFRS sides (40%) and only in 1 of 30 healthy sides (3%), (chi squared = 11.88, p = 0.0006). The presence of HC was more common in the AFRS vs healthy sides (7 of 30, 23.3% vs 2 of 30, 6.7%, respectively, p = 0.071). AN and SOEC presence was similar in both AFRS and healthy sides (p = 0.598 and p = 0.718 respectively).

CONCLUSION

AV are more common on the sides with AFRS compared to healthy sides, with the presence of CB reaching unquestionable statistical significance. Further study is needed to determine the possible association of AV, especially concha bullosa, with the pathophysiology of AFRS.

Bone Regeneration in Allergic Fungal Rhinosinusitis: Post-treatment Image Follow Up

Background: Bone erosion is a feature of allergic fungal rhinosinusitis (AFRS). The incidence of bone regeneration after treatment is unknown. The objective of this study is to evaluate the fate of bone erosion in AFRS.

Materials and methods: A retrospective chart review was conducted for all AFRS patients who had preoperative evidence of bone erosion on the computed tomography (CT) of the paranasal sinus (PNS) and at least one postoperative image. We used the bone erosion score (BES) as a valid tool to evaluate the preoperative bone erosion extension and the rate of regeneration on postoperative images.

Results: A total of 40 patients met our enrollment criteria. Of these, 30 patients underwent CT within nine months postoperatively (mean baseline BES: 9.07, SD: 8.11), 33 patients underwent CT between nine and 18 months postoperatively (mean baseline BES: 9.36, SD: 8.80), and 34 patients underwent CT after 18 months postoperatively (mean baseline BES: 8.56, SD: 7.69). The BES improved by 88.92% within nine months postoperatively with a follow-up BES of 0.93 (SD: 1.65), by 90.29% between nine and 18 months with a follow-up BES of 0.91 (SD: 2.15), and by 96.57% after 18 months with a follow-up BES of 0.29 (SD: 0.62). Complete bone regeneration occurred in 27 patients (67.50%); this was noted within nine months in 21 patients and after 18 months in six. Among them, 16 were male and 11 were female (p = 0.75). Regarding their ages, eight were pediatric and 19 were adult patients (p = 0.31).

Conclusion: Bone erosion in AFRS is a mostly reversible process. Complete bone regeneration occurred in more than two-thirds of patients within a short period of time.

Paranasal Sinus Wall Erosion and Expansion in Allergic Fungal Rhinosinusitis: An Image Scoring System

Background

Bone erosions are common in allergic fungal rhinosinusitis (AFRS). This study aimed at developing an image-based grading and scoring system for paranasal sinus (PNS) wall erosion in AFRS.

Methods

A retrospective review of all confirmed AFRS cases based on the Bent and Kuhn criteria was conducted. Preoperative computed tomography (CT) images were studied to detect PNS wall erosion with expansion. Based on our observation, we described a grading system based on the proportion of PNS wall erosion, with 1 if less thanone-third, 2 if between one-third and two-thirds, and 3 if more than two-thirds of the wall is eroded. This method provides a new scoring system ranging from 0 to 72. The inter-observer reliability of this scoring system was tested and the percent of agreement was found to be 90%.

Results

Among 142 AFRS cases, 82 patients (57.7%) had bone erosion. Orbital extension via lamina papyracea erosion occurred in 28.2% and 17.6% of the anterior and posterior ethmoid sinuses respectively, via floor erosion in 8.3% of the frontal sinuses, and via roof erosion in 2.1% of the maxillary sinuses. Intracranial extension caused by the anterior skull base erosion occurred in 19.4%, 10.9%, and 6% of the posterior ethmoid, anterior ethmoid, and frontal sinuses, respectively. The middle and posterior cranial fossa skull base was eroded in 14.4% and 9.2% of the sphenoid sinuses, respectively. Infratemporal extension occurred via erosion of the sphenoid sinus lateral wall in 17.3% of the sphenoid sinuses and via erosion of the maxillary sinus posterior wall in 6.7% of the maxillary sinuses. The mean of bone erosion score was 9.52, and the highest score was 34/72.

Conclusion

The orbit is the most common extra-sinus extension site via the lamina papyracea erosion. We propose a new grading and scoring system to assess disease severity and progress.

Bony orbital changes in allergic fungal sinusitis are reversible after treatment

Allergic fungal sinusitis (AFS) arises from a host hypersensitivity reaction to fungi residing within the sino-nasal tract. Computed tomography imaging may show heterogenous sinus opacification with bony erosion and expansion into the orbits. With advanced orbital involvement there is a risk of optic neuropathy and irreversible vision loss. We present a patient with AFS who presented with bilateral proptosis and early optic neuropathy. Radiologically, there was evidence of bony erosion and orbital wall compression. Following oral corticosteroids and full-house endoscopic sinus surgery, these changes reversed considerably. This case shows that bony and anatomical orbital changes from AFS are reversible with adequate surgical treatment.

Ophthalmic Manifestations of Allergic Fungal Sinusitis

PURPOSES

To study the ophthalmic manifestations of patients with allergic fungal sinusitis (AFS) and evaluate the importance of early diagnosis and management in preventing the possible future complications of AFS.

METHODS

Retrospective chart review of 100 patients with the diagnosis of AFS from a single institution was performed. Age, gender, clinical presentation including ophthalmic and radiological findings, immune status, patterns of sinus involvement, medical and surgical intervention needed, laboratory results, and the course of the disease were evaluated.

RESULTS

The mean age at presentation was 19.8 years (range, 10-42 years) with no clear gender predominance (52% of patients were female).The most common sinuses involved were ethmoid and maxillary sinuses. All patients underwent functional endoscopic sinus surgery and received systemic and topical steroids. There were no intervention-related complications. Thirty-four of 100 patients had ophthalmic consequences of AFS. The most common ophthalmic presentation was proptosis (n = 21, 61.7%), followed by epiphora (n = 5, 14.7%), visual loss (n = 4, 11.7%), diplopia (n = 3, 8.8%), and dystopia (n = 1, 2.9%) in addition to 1 patient having ptosis beside proptosis. CT scans of these 34 patients showed that 82.3% had nonhomogenous opacification of sinuses, 52% had erosion of lamina papyracea, 17.6% had intraorbital extension, and 8.8% had intracranial extension.

CONCLUSIONS

Ophthalmologists may be the first who encounter these patients which necessitates familiarity with AFS presentations and complications. In cases of sudden visual loss, early intervention may prevent permanent vision loss. Functional endoscopic sinus surgery and postoperative systemic and topical steroids resulted in dramatic improvement of ophthalmic symptoms and signs.

Neurological Complications of Acute and Chronic Sinusitis

PURPOSE OF REVIEW

Acute and chronic sinusitis can give rise to a wide array of intracranial and orbital complications. These complications include brain abscess, subdural empyema, epidural abscess, meningitis, venous sinus thrombosis, frontal bone osteomyelitis, and orbital cellulitis and abscess. Despite numerous medical advances, these complications carry a risk of mortality and significant morbidity.

RECENT FINDINGS

Recent studies have shown improvement in both the mortality and the morbidity associated with the neurologic complications of acute and chronic sinusitis. However, there are still a large portion of patients with long-term sequelae, and the literature reports a morbidity rate of approximately 30%. The most common post-treatment morbidities include permanent changes in vision, seizures, and hemiparesis. Although the overall incidence of neurologic complications from a sinogenic source are rare, the potential long-term complications can be devastating making prompt diagnosis and treatment vital to improving outcomes.

Role of diffusion-weighted imaging in skull base lesions: A pictorial review

Skull base lesions can be related to wide number of pathologies including infections, benign and malignant tumors. Accurate diagnosis and differentiation between these entities is important for prompt and appropriate treatment. However, computed tomography and routine magnetic resonance imaging techniques only provide information on the extent of the lesions, with limited ability to differentiate between benign and malignant lesions. Diffusion-weighted imaging can help in many such situations by providing additional information, including help in differentiating benign from malignant lesions, so that appropriate treatment can be initiated. In this review article, we illustrate the imaging findings of the spectrum of skull base lesions, emphasizing the role of diffusion-weighted imaging in this domain.

Bony Erosion Patterns in Patients with Allergic Fungal Sinusitis

Objective

To investigate bony erosion patterns in allergic fungal sinusitis (AFS) and to determine whether the extent of erosion correlates with demographics and preoperative clinical parameters.

Study Design

Retrospective review of prospectively collected data.

Methods

Seventy-four patients with a histopathologic diagnosis of AFS were identified. Preoperative computed tomographies (CT) were reviewed to determine sites with bony erosion. The 20-item Sinonasal Outcomes Test (SNOT-20) scores, endoscopy scores, and Lund-Mackay CT scores were compared between patients with and without bony erosion. Patients with bony erosion were further classified based on the extent of erosion. Statistical analysis was performed by using the Student's t-test and the χ2 test of independence.

Results

Of the 74 patients, 39 (52.7%) had bony erosion and 35 (47.3%) did not. Bony erosion was found to be associated with younger age (27.5 versus 36.0 years; p = 0.011) and African American race (p = 0.041). Preoperative CT scores correlated with the presence and extent of bony erosion (p = 0.010). Sex, race, number of previous surgeries, SNOT-20 scores, and endoscopy scores did not correlate significantly.

Conclusion

Younger age and African American race were found to significantly correlate with bony erosion in AFS, which indicated that a more severe inflammatory response was mounted in these patient groups. As expected, higher Lund-Mackay scores correlated with the severity of erosion. The lack of correlation with SNOT-20 scores indicated the insidious nature of this destructive disease. The level of evidence is 4.

Extensive Allergic Fungal Rhinosinusitis: Ophthalmic and Skull Base Complications

To review the clinical features, ophthalmic and skull base complications, radiologic correlates, surgical methods and outcomes in cases of extensive allergic fungal rhinosinusitis (AFRS). The retrospective review was carried out at a tertiary referral center and included 11 patients with extensive AFRS. Inclusion criteria were confirmed cases of AFRS with intracranial extension, gross erosion of the skull base or medial orbital wall and/or ophthalmic complications of AFRS, including visual loss. Acute bacterial or invasive fungal sinusitis and other non-AFRS sinus pathologies with orbital or skull base complications were excluded from the study. The mean age of patients was 22.7 years. Proptosis was the most common presenting feature followed by diplopia and visual loss. Four patients exhibited unilateral visual loss with one case of sudden acute onset. Intracranial extradural spread to the middle cranial fossa was observed in two cases with cavernous sinus involvement, destruction of the entire cranial base and extension to the petrous temporal bone. Ten patients exhibited co-existing orbital and skull base erosion whereas gross erosion of the lamina papyracea alone was seen in one patient. All patients underwent endoscopic sinus surgery with complete disease clearance. The minimum and maximum follow-up periods were 1 and 3 years, respectively with one documented recurrence 18 months after surgery. Visual recovery was complete after sudden vision loss whereas it was only partial or absent in patients with prolonged vision loss. Cases of extensive AFRS with ophthalmic and skull base complications pose diagnostic and therapeutic challenges and merit early intervention with long-term follow-up.

Quality of life, disability scores, and distress index in fungal rhinosinusitis

Our goal was to determine quality of life (QOL), disability, and distress in the day-to-day lives of patients suffering from fungal rhinosinusitis (FRS) based on a prospective questionnaire. The study included 125 patients suffering from FRS, excluding those with acute fulminant FRS and any other comorbid illness. The data were compared with data for 50 age- and sex-matched controls who did not have any other chronic illness and obtained outpatient services from the Department of Otolaryngology and Head and Neck Surgery of our institute. Analysis showed that patients with FRS had worse QOL, with an average score of 87.34 compared with 94.15 for the control group. QOL score further decreased to 85.31 for patients with extensive disease that included intracranial or intraorbital extension and to 71.1 in those with recurrent disease. Patients showed significant disability and had decreased work efficiency in disability parameters. Distress among these patients was also greater and further increased in those with extensive disease or recurrence. We conclude that patients with FRS have worse QOL, more disability, and more distress compared with age- and sex-matched controls. This issue needs to be addressed while treating cases of FRS.

Rhinotillexomania: a rare cause of medial orbital wall erosion

The authors report a rare case of medial orbital wall erosion with an orbital inflammatory mass and resultant lacrimal obstruction secondary to rhinotillexomania. A 67-year-old male with known history of compulsive nose picking (rhinotillexomania) sought treatment for complaints of watering in his OD. Examination revealed a blocked right inferior canaliculus. Nasal endoscopy showed a large nasal septal defect with multiple areas of crusting and bleeding. Hematologic investigations were normal. CT scan confirmed a large nasal septal and right medial orbital wall defect with an adjacent soft tissue mass in the medial orbit. Investigations ruled out systemic pathology. Histologic examination of medial orbital mass, sinus, and nasal mucosa revealed a reactive inflammatory infiltrate with surface Gram-positive cocci. The authors hypothesized that the patient had enlarged an existing nasal septal defect due to repetitive nose picking resulting in recurrent infection and inflammation of sinuses, leading to erosion of his medial orbital wall.
