Abstract
PURPOSE To report a case of acute rhino-orbital-cerebral aspergillosis with aggressive intracranial and orbital extension co-managed medically and surgically with endoscopic sinus debridement and multiple retrobulbar injections of amphotericin B. OBSERVATIONS A 70-year-old male patient presented via external transfer with headaches and left ophthalmoplegia concerning for severe complicated sinusitis with intracranial and left orbital spread. His history is notable for a simultaneous heart-kidney transplant three years prior on chronic immunosuppression. Ophthalmologic examination revealed complete ophthalmoplegia in the left eye with no light perception concerning for a left orbital apex syndrome. The patient was taken to the operating room twice for endoscopic sinus debridement and three separate retrobulbar injections of amphotericin B. Fungal cultures from surgical specimens grew isolated Aspergillus fumigatus. Patient's symptoms gradually improved and repeat MRI demonstrated resolution of pansinusitis, sparing left eye exenteration. CONCLUSIONS AND IMPORTANCE Multidisciplinary management of invasive fungal rhinosinusitis in the setting of profound immunosuppression poses a significant challenge. While surgical debridement remains the cornerstone approach, the achievable reduction in disease burden may be augmented by targeted retrobulbar antimicrobials.

Abstract
There was tremendous increase in the number of cases of mucormycosis among patients affected by coronavirus disease 2019 (COVID-19) during the second wave of pandemic in South Asian countries. This invasive fungal infection primarily affects paranasal sinuses and can have orbito-facial and intracranial extension. We are presenting the radiological findings of invasive mucormycosis with pathological and clinical outcome correlation. It is important for radiologists to have the knowledge of various presentations of this opportunistic infection for early diagnosis and helping clinicians in planning the appropriate line of management. The study also emphasizes on the correlation between the extent of involvement with clinical outcome and we proposed a magnetic resonance imaging (MRI) based scoring system to standardize and prognosticate the patients affected with mucormycosis. MATERIALS AND METHODS We utilized GE 1.5 tesla, 16-channeled MRI machine for scanning the clinically suspected mucormycosis patients and did plain and contrast study of the paranasal sinuses, orbito-facial study and included brain as and when required. Images were acquired in axial, coronal, and sagittal planes using T1, T2, and fat-saturated short tau inversion recovery sequences (STIR), fat-saturated contrast sequences for better evaluation of the extent of the disease. Diffusion-weighted sequence was also acquired to detect ischemic changes in optic nerve or brain parenchyma. Contrast study was used to detect any major vessel occlusion or cavernous sinus thrombosis in the study population. RESULTS Total number of cases (n) included in the study were 32. The mean age group was 41-50 years with the median age was 47 years. Out of 32 cases (n=32), in 16 cases (50%) the disease was limited only to the paranasal sinuses and in remaining 16 (50%) cases, disease has spread to other regions such as orbits, facial soft tissues, optic nerve, and brain parenchyma. All the 18 cases with Mild score (MRI ROCM score 1-3) survived and all those with severe score (2 cases) (MRI ROCM score 7-10) did not survive. CONCLUSION During the second wave of COVID-19 pandemic, we observed a significant rise in acute invasive mucormycosis infection primarily involving the paranasal sinuses and spread to orbito-facial, cerebral parenchyma causing related complications and hence increased morbidity and death. Radiologically, using MRI, it was effectively possible to detect early extrasinonasal spread and other fatal complications thereby guiding the physicians and surgeons in the proper early aggressive management of the disease. Here, we have described the radiological characteristics of paranasal sinus mucormycosis and its spread to other regions. We also proposed an MRI-based Scoring System for standardized assessment of the disease severity. We observed in our study that the extent of disease on MRI is directly correlating with mortality.

Abstract
Purpose Increased incidence of acute invasive fungal rhinosinusitis (AIFR) in the setting of COVID-19 is undeniable. This can be attributed to its effect on innate immunity and extensive use of corticosteroids. The goal of our study was to assess the orbital complications of AIFR and its management in the COVID-19 convalescent patients. Methods Our longitudinal prospective study included 45 patients with orbital complications of AIFR in recently recovered COVID-19 patients. We performed otorhinolaryngological, ophthalmological, and neurological examinations to monitor the manifestations of the disease. Computed tomography and contrast enhanced magnetic resonance imaging were performed to detect the extent of infection. Antifungal medications, surgical intervention, and general condition management were all provided to all the patients. Results We reported pre-septal cellulitis, orbital cellulitis, and orbital apex syndrome in 18, 13, and 10 patients, respectively. Four patients had cavernous sinus thrombosis. Mucormycosis and Aspergillus species were detected in 80% and 11.11% of our patients, respectively, while the mixed infection was found in 8.88% of our patients. Diabetes mellitus was the most common cause of immunocompromise (95.55% of our patients). Orbital pain and ophthalmoplegia were the most common ocular manifestations, followed by proptosis and relative afferent pupillary defect. All patients underwent surgical intervention, except for one patient who was unfit for surgery. One patient had orbital exenteration. The ophthalmological manifestations were reversible in cases of orbital and pre-septal cellulitis. The overall survival rate was 66.67%. Conclusion Early diagnosis and treatment of AIFR can decrease the morbidity and mortality rate of affected patients.

Abstract
COVID-19 is not only limited to a defined array but also has expanded with several secondary infections. Two uncommon opportunistic fungal infections, COVID-19 associated mucormycosis (CAM) and aspergillosis (CAA), have recently been highly acquainted by many worldwide cases. Two immune response deteriorating factors are considered to be responsible for immunosuppression: comorbidities and medication. Due to unlike infection sites and patterns, CAM and CAA-associated factors deflect a few degrees of proximity, and the present study is for its assessment. The study evaluated 351 CAM cases and 191 CAA cases retrieved from 65 and 53 articles based on inclusion criteria, respectively. Most of the CAM reported from India and CAA were from four South-European and West-European neighbor countries. The mean ages of CAM and CAA were 52.72 ± 13.74 and 64.81 ± 11.14, correspondingly. Mortality of CAA (56.28%) was two times greater than CAM (26.02%). Nevertheless, the count of diabetes cases was very high in CAM compared to CAA. The main comorbidities of CAM were diabetes (nearly 80%) and hypertension (more than 38%). All noticeable complications were higher in CAA except diabetes, and these were diabetes (34.55%), hypertension (45.03%), and obesity (18.32%). Moreover, pre-existing respiratory complications like asthma and chronic obstructive pulmonary disease are visible in CAA. The uses of steroids in CAM and CAA were nearly 70% and 66%, respectively. Almost one-fourth of CAA cases were reported using immunosuppressant monoclonal antibodies, whereas only 7.69% were for CAM. The overall finding highlights diabetes, hypertension, and steroids as the risk factors for CAM, whereas obesity, chronic pulmonary disease, and immunosuppressants for CAA.

Abstract
This study aimed to determine the patient demographics, risk factors, which include comorbidities, medications used to treat COVID-19, and presenting symptoms and signs, and the management outcome of COVID-19-associated invasive fungal sinusitis. A retrospective, propensity score-matched, comparative study was conducted at a tertiary care center, involving 124 patients with invasive fungal sinusitis admitted between April 2021 and September 2021, suffering from or having a history of COVID-19 infection. Among the 124 patients, 87 were male, and 37 were female. A total of 72.6% of patients received steroids, while 73.4% received antibiotics, and 55.6% received oxygen during COVID-19 management. The most common comorbidities were diabetes mellitus (83.9%) and hypertension (30.6%). A total of 92.2% had mucor, 16.9% had aspergillus, 12.9% had both, and one patient had hyalohyphomycosis on fungal smear and culture. The comparative study showed the significant role of serum ferritin, glycemic control, steroid use, and duration in COVID-19-associated invasive fungal disease (p < 0.001). Headache and facial pain (68, 54.8%) were the most common symptoms. The most involved sinonasal site was the maxillary sinus (90, 72.6%). The overall survival rate at the three-month follow-up was 79.9%. COVID-19-related aggressive inflammatory response, uncontrolled glycemic level, and rampant use of steroids are the most important predisposing factors in developing COVID-19-associated invasive fungal sinusitis.

Abstract
Mucormycosis is a life threatening, opportunistic infection often seen in individuals with a weak immune system. With an upsurge of cases of Covid-19, a drastic increase in cases of Rhino-Orbito-Cerebral Mucormycosis is being witnessed at present. This article has been written with the purpose of understanding the factors responsible for it and the challenges it brings along for the Indian health-care system at present. Possible solutions for dealing with these problems have also been included in the manuscript.
Google, PubMed and ENT Cochrane databases were searched without a time limit using key words like “Mucormycosis”, “Rhino-cerebral-mucormycosis” in conjunction with “COVID-19” and “SARS CoV-2”. We found 34 articles to be relevant and hence included them to write this review. Rhino-Orbito-Cerebral Mucormycosis is being seen due to coming together of the three entities-the agent, host and environment that constitute the epidemiological triad for this disease in India. Responsible factors are uncontrolled diabetes mellitus, overzealous use of steroids and antibiotics and other environment related issues. The solutions for these problems lie in spreading awareness about prevention of these practices along with early diagnosis and treatment of mucormycosis. To deal effectively with this situation, particularly when there is an existing overload on otolaryngologists and the rest of the health-care system, a multipronged and multilevel collaborative approach is the need of the hour. With effective Standard Operating Procedures and guidelines promoting a multidisciplinary approach for early diagnosis and treatment, we can surely overcome this situation.

Abstract
Coronavirus disease 2019 (COVID-19) has been found to be associated with mucormycosis in few parts of the world, especially India. It is important to look for reasons for this upsurge of cases so that other countries may take proper steps to prevent it. A prospective clinico-demographic study was conducted in SMS Medical College, Jaipur, India from April to May 2021. All patients (235) with COVID associated mucormycosis (CAM) were studied in detail with reference to their diabetic status and steroid intake during treatment of COVID-19. Steroid usage was in 84.3% of patients with methylprednisolone being the most commonly used steroid (66.8%). Majority of the patients had taken steroids for 7–14 days. Diabetes was found in 204 patients and 42.1% of patients were newly diagnosed during/after COVID-19 treatment. The HbA1c levels of diabetic patients ranged from 6.0% to 16.3%. This is perhaps the biggest study in the world shows that the triad of COVID-19, diabetes and steroid usage is a major contributing factor towards mucormycosis. Proper steps should be taken to prevent CAM.

Abstract
The predisposing factors of invasive fungal disease in COVID 19 infection are still debatable because of the limited human understanding of the virus with the current literature. In this study, we have tried to correlate the various predisposing factors influencing the clinical profile and treatment outcomes in patients with covid associated mucormycosis (CAM). It is a retrospective analysis of cases of CAM during the second wave of COVID 19 infection, which was managed in the department of Otorhinolaryngology from Dec 1, 2020, to June 10, 2021. The detailed clinical, radiological and management of patients with CAM were collected, recorded, evaluated and correlated with the predisposing factors. Of the total, 46 patients, 44(95.65%) were diabetic and 41 patients had a previous history of steroid intake. When clinical parameters were compared between blood sugar < 200 mg/dl and > 200 mg/dl, the old and newly diagnosed diabetes mellitus in patients with CAM, there was no significant differences in any of the above clinical parameters (p > 0.05), except the hospital stay (p = 0,004). Steroid intake in patients with coexisting DM associated with CAM is considered the most important factor for the development of the CAM. There was are no significant difference in any of the clinical/treatment outcomes in patients with CAM with respect to the initial blood sugar, except for the hospital stay. A large sample size with a long-term follow-up period may be needed for a better understanding of common predisposing factors for the development of CAM.

Abstract
Patients with severe COVID-19, such as individuals in intensive care units (ICU), are exceptionally susceptible to bacterial and fungal infections. The most prevalent fungal infections are aspergillosis and candidemia. Nonetheless, other fungal species (for instance, Histoplasma spp., Rhizopus spp., Mucor spp., Cryptococcus spp.) have recently been increasingly linked to opportunistic fungal diseases in COVID-19 patients. These fungal co-infections are described with rising incidence, severe illness, and death that is associated with host immune response. Awareness of the high risks of the occurrence of fungal co-infections is crucial to downgrade any arrear in diagnosis and treatment to support the prevention of severe illness and death directly related to these infections. This review analyses the fungal infections, treatments, outcome, and immune response, considering the possible role of the microbiome in these patients. The search was performed in Medline (PubMed), using the words "fungal infections COVID-19", between 2020-2021.

Abstract
Visual impairment can occur because of several mechanisms, including optic nerve disease and occasionally fungal sinusitis. An 87-year-old man presented with the loss of right visual acuity; he was diagnosed with optic neuritis. Steroid pulse therapy was not effective. One month later, he became unconscious because of meningitis, following which treatment with ceftriaxone and acyclovir was initiated. However, his consciousness deteriorated because of a subarachnoid hemorrhage caused by a ruptured aneurysm. Meningitis and vascular invasion caused by fungal rhinosinusitis were suspected, and the sinus mucosa was biopsied. He was pathologically diagnosed with invasive Aspergillus rhinosinusitis. Despite continuous liposomal amphotericin B administration, he died of cerebral infarction, following a right internal carotid artery occlusion. It is important to consider the possibility of Aspergillus as an etiological agent, especially when cerebrovascular events are associated with visual impairment.

Abstract
Background Fungal involvement of the paranasal sinuses has been described more than two centuries ago. In the current article, it is referred to as fungal rhinosinusitis (FRS) which is a general term that is used to describe a spectrum of pathologically, immunologically, and clinically different disease entities affecting the paranasal sinuses where fungus is thought to be the major potential etiology. Objective To determine the incidence and spectrum of FRS in Singapore and to compare our findings with international figures through literature review. Methods A retrospective review of the clinical charts, radiological and laboratory results, and operative reports of all patients who underwent endoscopic sinus surgery at an ENT department of a tertiary referral hospital in Singapore over five-year period. Results Out of 533 functional endoscopic sinus surgeries performed during the period of the study for management of chronic rhinosinusitis, 44 (8.4%) were found to fit the criteria for diagnosis of FRS. Twenty (45.5%) were eosinophilic FRS and 24 (54.5%) were fungal balls. Invasive FRS has not been encountered. Clinical presentation, investigations, and management of both groups of patients are discussed. Conclusion Fungal rhinosinusitis is not uncommon in Singapore. Fungal ball and eosinophilic mucin fungal rhinosinusitis are among the most common forms encountered in this part of the world.

Treatment outcomes in acute invasive fungal rhinosinusitis extending to the extrasinonasal area. Sci Rep 2020; 10:3688. [PMID: 32111952 PMCID: PMC7048759 DOI: 10.1038/s41598-020-60719-7] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/07/2019] [Accepted: 02/14/2020] [Indexed: 11/08/2022] Open
Abstract
Acute invasive fungal rhinosinusitis (AIFRS) can spread beyond the sinonasal cavity. It is necessary to analyze the association between the specific site involved in the extrasinonasal area and the survival rate to predict patient prognosis. We investigated 50 patients who had extrasinonasal lesions on preoperative gadolinium (Gd)-enhanced magnetic resonance imaging (MRI) scan and underwent wide surgical resection of AIFRS. The specific sites with loss of contrast enhancement (LoCE) on Gd-enhanced MRI were analyzed for AIFRS-specific survival rate. The most common underlying disease was diabetes mellitus followed by hematological malignancy. The most common symptoms were headache and facial pain. Seven patients (14.0%) expired because of AIFRS progression. Poor prognosis was independently associated with LoCE at the skull base on preoperative MRI (HR = 35.846, P = 0.004). In patients with AIFRS extending to the extrasinonasal area, LoCE at the skull base was an independent poor prognostic factor.

Abstract
Objectives This study aimed to evaluate the clinical characteristics of maxillary sinus fungus ball (MFB) to increase the preoperative diagnostic accuracy. Methods A retrospective review of 247 patients who underwent endoscopic sinus surgery for unilateral maxillary sinusitis from January 2015 to December 2017 at a single institution was performed. Patients with pathologically proven MFB were compared to those with unilateral chronic maxillary sinusitis (CMS). Patient demographics and computed tomography (CT) findings were evaluated. The CT features were categorized as intralesional hyperdensity (calcification), the irregular lobulated protruding lesion (fuzzy appearance), maxillary sinus full haziness without mass effect, maxillary sinus full haziness with mass effect, and others. A regression tree analysis was performed. Results In total, 247 patients were analyzed; among them, 179 (72.5%) had MFB and 68 (27.5%) had CMS. MFB showed predominance in older individuals. Among the radiological features, intralesional hyperdensity was most commonly associated with MFB. The presence of a fuzzy appearance or full opacity with mass effect was also associated with MFB. The highest area under the curve was noted with the regression tree analysis based on the model, which included the presence of intralesional hyperdensity, demographic data (age), and presence of fuzzy appearance or maxillary sinus full haziness with mass effect in case of absence of intralesional hyperdensity (0.904). Conclusion A simple algorithm to optimize the preoperative diagnosis of MFB was developed. Physicians should be aware of such findings in the management of patients presenting with unilateral CMS.

Aspergillus fumigatus biofilm formation on different bone substitutes used in maxillary sinus augmentation: an in vitro analysis. Int J Implant Dent 2019; 5:22.

Abstract
Background Fungus ball (FB) typically affects healthy adults, and Aspergillus fumigatus is the most frequent etiologic agent: iatrogenic factors represent an important issue in FB pathogenesis. Moreover, a recent study suggested a significant association between the use of anorganic bovine bone as sinus grafting material and subsequent development of FB. The aim of the present investigation is to evaluate in vitro eventual differences in the ability of Aspergillus fumigatus to colonize different bone grafting materials and grow on them as biofilm. Findings Five different bone substitutes (demineralized bone matrix, anorganic bovine bone, ß-tricalcium phosphate, synthetic nano-hydroxyapatite, and synthetic hydroxyapatite), commonly used in sinus floor augmentation procedures, were inoculated with conidia suspensions of A. fumigatus and incubated at 37 °C for 4 and 8 h, in standardized conditions. Biofilm bound to the different materials underwent quantitative and qualitative analysis by confocal and scanning electron microscopy. A. fumigatus proved to be able to adhere and form biofilm on all the tested bone substitutes. The surface plot representation of the samples displayed some differences in the density of the superficial layer, due to the physical characteristics of the biomaterials. Nevertheless, Kruskal–Wallis test showed no significant differences in biomass amount among the five bone substitutes (p = 0.236 and p = 0.55 after 4 and 8 h adhesion, respectively). Conclusions All the bone substitutes normally used in sinus floor augmentation represent a favorable substrate for fungal growth, due to their physical and chemical characteristics. During sinus floor elevation procedures, Schneiderian membrane integrity should be maintained in order to avoid the exposure of the grafting material at the respiratory environment, with potential risks of fungal colonization.

Abstract
Objective: The purpose of this study was to investigate the characteristics of this unique form of rhinosinusitis. Methods: Ninety-one patients with sinus fungus balls were evaluated for clinical characteristics. Nasal tissues obtained from 38 patients with sinus fungus ball, along with 26 controls were used for histopathological, cytokines/chemokines, western blotting, and genetic analyses. Results: Patients with fungus balls had significantly more females and their age was older. The presentation of fungus ball was predominantly unilateral (97.8%). Thirty-three patients (36.3%) had risk factors for fungal infection. Macrophage and neutrophil dominated cellular infiltration was found in nasal tissues of fungus ball patients. A tendency of reduced tight junction staining (e-cadherin) and protein expression was found. Interleukin 8 (IL8) and granulocyte colony stimulating factor (G-CSF) significantly increased in sinus fungus ball tissue homogenates when compared with those from controls. Higher prevalence of a single single nucleotide polymorphism (SNP) with E-cadherin was found in the patients with fungus ball. Conclusions: We found that patients with sinus fungus ball had robust immune responses, allowing recruitment and activation of macrophages and neutrophils. However, patients with sinus fungus ball could have genetic or acquired weakness in immunity. The fungal hyphae were localized and accumulated within single sinus instead of being eradicated by host.

Abstract
Fungus ball of maxillary sinus generally affects immunocompetent and nonatopic subjects. Although endoscopic removal is the current gold standard treatment, removal is at times difficult due to an accumulation of fungal elements in the anterior ad inferior recesses. Aim. To present our experience of maxillary fungus ball treated by the “gauze technique” that avoids these removal difficulties. Materials and Methods. A retrospective, cross-sectional, and descriptive study of 25 patients affected by maxillary fungus ball was carried out: 19 were treated by the “gauze technique” and 6 were treated without “gauze technique.” Results. A comparison was made between the two groups for surgery procedure time, length of hospitalization, time from surgery to nasal unpacking, complications, and postsurgical patient satisfaction. The only statistically significant difference observed was a shorter surgical procedure time (p < 0.05) for the “gauze technique.” Conclusions. The data obtained in this study demonstrated that the “gauze technique” is a safe, simple, and quick technique, able to reduce surgery procedure time whilst providing excellent functional outcomes and patient satisfaction.

Abstract
An otherwise healthy 34-year-old man was referred to our ear, nose and throat (ENT) clinic for a bilateral maxillary radiologic opacity. This condition was accidentally discovered with a panoramic radiography performed during a follow-up visit after a bilateral endodontic treatment. The patient did not report any specific sinonasal symptom such as purulent nasal discharge, loss of smell and cough, apart from an unspecific sinus pressure. The CT scans showed a bilateral inflammatory process into the maxillary-ethmoidal sinuses and an iron-like density within the maxillary sinuses, while nasal endoscopy showed purulent discharge in the ostiomeatal complex. The patient underwent functional endoscopic sinus surgery under general anaesthesia and the inflammatory material collected was histologically diagnosed as a rare case of bilateral fungus ball. The patient was dismissed the following day with no complications; there were not any sign of recurrence or symptoms during a 4 month follow-up.

Abstract
A 63-year-old man presented to the outpatient department of our tertiary care hospital, with unilateral left nasal obstruction, foul smelling nasal discharge and occasional mild epistaxis. On examination, a hard greyish black mass was noted in the anteroinferior portion of the inferior turbinate, with extension posteriorly into the inferior meatus with surrounding unhealthy granulation tissue. Provisional diagnosis of rhinolith was surprisingly reversed by histopathology, which suggested the presence of an Aspergillus fungus ball with Actinomyces colonisation.

Abstract
Chronic rhinosinusitis (CRS) is a relevant and prevalent medical condition in Germany, Europe and the world. If analysed in detail, the prevalence of CRS shows regional and temporary variety. In this review, currently available data regarding the prevalence of CRS is therefore sorted by country and/or region, time point of data collection and the CRS-definition employed. Risk factors like smoking and gastroesophageal reflux are discussed regarding their influence on CRS prevalence. Moreover, comorbidities of CRS, like asthma, conditions of the cardiovascular system and depression are listed and their influence on CRS is discussed. Furthermore, data on CRS prevalence in special cohorts, like immunocompromised patients, are presented. To estimate the economic burden of CRS, current data e.g. from Germany and the USA are included in this review.

Abstract
Fungus ball in the concha bullosa is an extremely rare disease. We described a case of the fungus ball in the concha bullosa in a 22-year-old woman. Preoperative diagnosis was based on nasal endoscopy and computed tomography scanning. The patient was endoscopically operated on. The examination of the removed material was reported as fungal infection. This case was found worth writing because of the location of the concha bullosa and its rare occurrence in this location.

Abstract
Rhinosinusitis is the inflammation of the mucous membranes of nose and paranasal sinus(es). 5-13% of upper respiratory tract infections in children complicate into acute rhinosinusitis. Though not life threatening, it profoundly affects child's school performance and sleep pattern. If untreated, it could progress to chronic rhinosinusitis (CRS). The pathogens involved in perpetuation of CRS consist of multidrug-resistant mixed microflora. CRS is challenging to manage and could further extend to cause eye or intracranial complications. In children, CRS diagnosis is often either missed or incomprehensive. Due to this, morbidity and strain on healthcare budget are tremendous. Flexible fiberoptic endoscopy has revolutionized management of CRS. Its utility in children is being increasingly recognized. Optimal management entails specific appropriate antimicrobials as well as treatment of underlying causes. The aim is to normalize sinus anatomy and physiology and regain normal mucociliary function and clearance.

Abstract
OBJECTIVES Acute invasive fungal rhinosinusitis (AIFR) is an aggressive fungal infection in immunocompromised patients with high mortality rates. The aim of this study is to present our experiences on endonasal treatment in immunocompromised pediatric hematology-oncology patients with AIFR. METHODS Thirteen pediatric hematology-oncology patients treated for AIFR between March 2006 and December 2011 were analyzed retrospectively. We reviewed the following data for all patients: age, gender, predisposing disease, initial symptoms, pathological diagnosis, microbiological results, laboratory findings, surgical procedure, number of operations and treatment outcomes. RESULTS Nine of 13 patients with lesions confined to sinonasal cavity were operated with endoscopic approach. Open surgery was performed in four patients, three of them had palatal and buccal lesions and one had facial skin involvement. Endoscopic approach was also used for sinonasal lesions of these four patients. A total of 7 patients died: 4 patients with progression of the underlying disease, 2 patients with sepsis and 1 patient due to renal failure. Survival rate in surgically treated patients was found 46% (6/13 patients). CONCLUSIONS Endonasal endoscopic approach is both feasible and efficient technique, also enables excellent local control with less morbidity compared to open surgery. This approach is suitable for patients who are diagnosed in the early stages of AIFR and also presents a less traumatic option for patients with poor health status. Open surgical procedure should be preferred in patients with disease extending out of the sinonasal cavity.

Abstract
ABSTRACT
Invasive sinus Aspergillus infection has been reported in the last decade with increased frequency, most commonly in the setting of hematologic malignancy, neutropenia, HIV infection and other states of immunosuppression. Fungal rhinosinusitis can be broadly classified into two varieties-invasive and noninvasive on the basis of tissue invasion. Invasive fungal sinusitis are acute invasive, chronic invasive (both granulomatous and nongranulomatous forms), whereas noninvasive are fungus balls and allergic fungal sinusitis. Invasive fungal sinusitis is one of the most challenging forms of sinonasal pathology to manage, most commonly presenting in immunocompromised individuals. Chronic invasive being sinus aspergillosis (CISA) is being reported in immunocompetent patients at an increasing rate while most of these cases are being reported from the India subcontinent and middle east. Invasive fungal sinusitis is on the rise worldwide and especially in north India as it is endemic in this part of the country. It is affecting immunocompetent young and middle aged population causing a great morbidity and mortality. This entity needs to be picked up early by spreading awareness among the family physicians, internists, otolaryngologists, ophthalmologists, neurosurgeons, pulmonary physicians, critical care specialists so that an early management can initiated to achieve better control over the disease. This review is an attempt to initiate an interdisciplinary approach to achieve a better outcome.

Abstract
Allergic Aspergillus sinusitis (AAS) is a three decade old clinicopathologic entity in which mucoid impaction akin to that of allergic bronchopulmonary aspergillosis (ABPA) occurs in the paranasal sinuses. Features such as radiographic evidence of pansinusitis, passage of nasal plugs and recurrent nasal polyposis in patients with an atopic background is suggestive of AAS. Histopathlogic confirmation from the inspissated mucus is a sine qua non for the diagnosis. Heterogeneous densities on computed tomography of the paranasal sinuses are caused by the 'allergic mucin' in the sinuses. Many patients give a history of having undergone multiple surgical procedures for symptomatic relief. The current approach to treatment appears to include an initial surgical debridement followed by postoperative oral corticosteroids for long durations. Although both ABPA and AAS are classified as Aspergillus-related hypersensitivity respiratory disorders, their co-occurrence appears to be an infrequently recognised phenomenon. This could perhaps be attributed to the fact that these two diseases are often treated by two different specialties. A high index of suspicion is required to establish the diagnoses of ABPA and AAS. All patients with asthma and/or rhinosinusitis along with sensitisation to Aspergillus antigens are at an increased risk of developing ABPA and/or AAS. ABPA must be excluded in all patients with AAS and vice versa. Early diagnosis and initiation of appropriate therapy could plausibly alter the course of the disease processes and prevent the possible development of long term sequelae.

Abstract
The complex regional anatomy of the nose and paranasal sinuses makes the interpretation of imaging studies of these structures intimidating to many radiologists. This paper aims to provide a key to interpretation by presenting a simplified approach to the functional anatomy of the paranasal sinuses and their most common (and most relevant) variants. This knowledge is basic for the full understanding of chronic rhinosinusitis and its computed tomography (CT) patterns. As fungal infections may be observed in the setting of chronic rhinosinusitis, these are also discussed. Chronic sinus inflammation produces bone changes, clearly depicted on CT images. Finally, clues to suspecting neoplastic lesions underlying inflammatory sinus conditions are provided.

Abstract
BACKGROUND Fungal (rhino-) sinusitis encompasses a wide spectrum of immune and pathological responses, including invasive, chronic, granulomatous, and allergic disease. However, consensus on terminology, pathogenesis, and optimal management is lacking. The International Society for Human and Animal Mycology convened a working group to attempt consensus on terminology and disease classification. DISCUSSION Key conclusions reached were: rhinosinusitis is preferred to sinusitis; acute invasive fungal rhinosinusitis is preferred to fulminant, or necrotizing and should refer to disease of <4 weeks duration in immunocompromised patients; both chronic invasive rhinosinusitis and granulomatous rhinosinusitis were useful terms encompassing locally invasive disease over at least 3 months duration, with differing pathology and clinical settings; fungal ball of the sinus is preferred to either mycetoma or aspergilloma of the sinuses; localized fungal colonization of nasal or paranasal mucosa should be introduced to refer to localized infection visualized endoscopically; eosinophilic mucin is preferred to allergic mucin; and allergic fungal rhinosinusitis (AFRS), eosinophilic fungal rhinosinusitis, and eosinophilic mucin rhinosinusitis (EMRS) are imprecise and require better definition. In particular, to implicate fungi (as in AFRS and EMRS), hyphae must be visualized in eosinophilic mucin, but this is often not processed or examined carefully enough by histologists, reducing the universality of the disease classification. A schema for subclassifying these entities, including aspirin-exacerbated rhinosinusitis, is proposed allowing an overlap in histopathological features, and with granulomatous, chronic invasive, and other forms of rhinosinusitis. Recommendations for future research avenues were also identified.

Abstract
A fungus ball is usually found in just one sinus, often the maxillary sinus, followed by the sphenoid, ethmoid, and frontal sinuses. We report the case of a fungus ball in the inferior meatus of a 50-year-old woman, which was successfully removed by nasal endoscopic surgery. This is the first case to our knowledge that has been reported at this unusual site. In addition, we hypothesise that "inferior meatus fungus ball" is a disease entity similar to a sinus fungus ball.

Abstract
BACKGROUND AND OBJECTIVES Allergic fungal sinusitis (AFS) is a relatively newly recognized entity consisting of a pansinusitis with allergic mucinous infiltrates in all involved sinuses. Historically mistaken for a paranasal sinus tumor, AFS is believed to be an allergic reaction to aerolized environmental fungi, usually of dematiaceous and Aspergillus species, in an immunocompetent host. We determined the occurrence of AFS in patients with chronic rhinosinusitis (CRS) to identify accurate preoperative parameters for AFS, as well as to identify the common fungi causing AFS in Saudi Arabia. METHODS We conducted a retrospective chart review of 406 cases of CRS undergoing functional endoscopic sinus surgery from 2001 to 2005. Data regarding patient demographics, presenting symptoms, ENT examination, laboratory and radiological features, histopathological features and fungal culture was collected and analyzed. RESULTS Fungal cultures were positive in 69 (16.9%) cases of CRS. Based on radiological features, histopathologic findings and culture results, AFS was diagnosed in 59 (14.5%) cases. Nasal polyposis was present in 56 (94.9%) cases; multiple sinuses were affected in all cases. Aspergillus species was the commonest causative fungal pathogen, being isolated in 40 (67.8%) cases, whereas dematiaceous fungi were isolated in 19 (32.2%) cases. CONCLUSIONS AFS has been an underdiagnosed clinical entity. Only increased awareness among physicians of fungal involvement will increase accuracy of diagnosis.

Abstract
Paranasal sinus development and pneumatisation variants are described, and rhinosinusitis and different patterns of inflammatory sinonasal diseases are reviewed. Other inflammatory sinonasal diseases, e.g., fungal sinusitis, mucocele, pyocele and sinonasal manifestations in systemic diseases, are briefly described. Computed tomography (CT) is the primary modality in diagnosing and mapping suspected inflammatory sinonasal disease. Magnetic resonance (MR) imaging is complementary to CT if fungal sinusitis, pyocele or malignancy are suspected.

Abstract
Aspergillus spp. produce a wide range of invasive and sapropytic syndromes which may involve any tissue. Within a given tissue or organ the pathology and pathogenesis varies enormously, ranging from angioinvasive disease to noninvasive saprophytic disease. The individual invasive and saprophytic syndromes in which a causative role can be attributed to Aspergillus spp. are detailed specifically with reference to the underlying pathology and pathogenesis, the clinical setting and features, and the manner in which a diagnosis can be established.

Abstract
UNLABELLED Here we evaluated a possible relationship between chronic hyperplastic sinusitis (CHS) and moisture exposure and secondly a seasonal variation of fungal and bacterial findings in the healthy nose. In 28 CHS patients sinus mucus was collected during endoscopic sinus surgery. Samples from the nasal cavities of 19 healthy volunteers were collected by nasal lavage (NAL) in January and in September. Bacterial culture and fungal staining and culture were carried out. Histological samples from the sinus mucosa were obtained. Patients' medical history and environmental factors were enquired. Mold odor or moisture problems in the home or work environment were reported by 46% of the CHS patients. Patients who reported moisture exposure did not differ significantly from those who had not been exposed with regards to microbiological findings, tissue eosinophilia, and earlier operations. Cladosporium (16%) and Alternaria (11%) were found in NAL fluid collected in the autumn from the control subjects. No fungi were isolated from samples taken during the winter. An association between CHS or fungal sinusitis and moisture damage was not apparent in the present study. The fungal findings in the nasal cavity reflect the environmental exposure. This should be taken into account when NAL is used for microbiological studies. PRACTICAL IMPLICATIONS Living in a moldy house or working in a similar environment may increase the risk of respiratory symptoms and infections. However, our results suggest that chronic hyperplastic sinusitis and fungal sinusitis are not associated with moisture exposure. The nose is a good collector of particles in the air. Especially samples taken by the nasal lavage method reflect the environmental exposure. This should be taken into account when this method is used for microbiological studies.

Abstract
In the invasive forms of fungal sinusitis rapid identification of etiologic agent is of vital importance because of the different reaction of the fungi to various antifungal agents. In the non-invasive forms it is of interest for epidemiologic reasons and because of the potential transition to invasive and generalized mycoses in case of additional immunodeficiency. A diagnosis of fungal genus in histologic slides is desirable since up to 70% of the fungal cultures remain without result.In the present study 77 cases of fungal sinusitis were examined with the comercially available antibodies Anti-Aspergillus and Anti-Rhizomucor. The results of the histological examination and fungal cultures were added. The immunohistochemical examination permitted in 64 cases a classification as Aspergillus/Penicillium. Two cases caused by Zygomyzetes alone or in combination could be confirmed immunohistochemically. Four fungus balls showed no significant immunoreaction with both antibodies. If these where caused by other Hyphomycetes p.e. Pseudallescheria or if it where Aspergillus fungus balls that did not react because of extreme regressive change can not be decided.

Abstract
OBJECTIVE The purpose was to show the capacity of zinc oxide and eugenol to affect the growth of Aspergillus fumigatus. STUDY DESIGN An in vitro microbiological analysis was conducted on samples from infected maxillary sinuses and on 3 different endodontic sealers. RESULTS Tests showed that zinc oxide in solution favors the growth of Aspergillus fumigatus, while eugenol inhibits this growth, even when mixed with zinc oxide powder. This inhibiting effect decreases over time. A reduced effectiveness was demonstrated over a 75-day period. CONCLUSIONS The hypothesis is that the diminishing concentration of eugenol over time in endodontic sealers allows the zinc oxide to support growth of Aspergillus fumigatus. This is reinforced by clinical experience, where mycetoma has developed years after endodontic therapy with excess sealer in the maxillary sinus.

Abstract
Allergic fungal sinusitis is a form of noninvasive fungal disease resulting from an IgE-mediated hypersensitivity reaction in atopic individuals. Allergic fungal sinusitis can present with a continuum of symptoms. Accumulation of allergic inspissated mucin may cause simple nasal obstruction or progress to facial deformity with osteolytic destruction and intracranial extension. Multiple species of fungi are now recognized as etiologic factors responsible for initiating the inflammatory response. This article discusses 3 cases involving Aspergillus and Curvularia species, and reviews diagnostic image findings, pathophysiology, and medical-surgical management of this increasingly common disease.

Abstract
Acute invasive fungal rhinosinusitis is a difficult disorder to diagnose and treat. A systematic approach to the susceptible patient, however, leads to an earlier diagnosis with improved survival. Early evaluation with rigid nasal endoscopy with frozen section biopsy of suspicious lesions or the middle turbinate should be considered in the high-risk population. Complete surgical resection and the reversal of neutropenia appear to be critical elements in achieving a successful outcome in patients with invasive fungal rhinosinusitis.

Abstract
Chronic invasive fungal rhinosinusitis is an increasingly recognized, but inadequately characterized, disease entity which is separate and distinct from acute fulminant invasive fungal sinusitis and allergic fungal sinusitis. Chronic invasive fungal rhinosinusitis is divided into granulomatous and nongranulomatous subtypes based on histopathology, but the clinical distinction between the two subtypes is not clear. Current management includes varying degrees of surgical débridement and a prolonged course of antifungal agents. A protracted clinical course with recurrence after treatment is common.

Abstract
Neoplastic disease of the nose, paranasal sinuses, the nasopharynx and the parapharyngeal space requires thorough assessment of location and extent in order to plan appropriate treatment. CT allows the deep soft tissue planes to be evaluated and provides a complement to the physical examination. It is especially helpful in regions involving thin bony structures (paranasal sinuses, orbita); here CT performs better than MRI. MRI possesses many advantages over other imaging modalities caused by its excellent tissue contrast. In evaluating regions involving predominantly soft tissue structures (ec nasopharynx and parapharyngeal space) MRI is superior to CT. The possibility to obtain strictly consecutive volume data sets with spiral CT or 3D MRI offer excellent perspectives to visualize the data via 2D or 3D postprocessing. Because head and neck tumors reside in a complex area, having a 3D model of the anatomical features may assist in the delineation of pathology. Data sets may be transferred directly into computer systems and thus be used in computer assisted surgery.
