Features of Importance in Nasal Endoscopy: Deriving a Meaningful Framework.

Critical components of the nasal endoscopic examination have not been definitively established for either the normal examination or for clinical disorders. This study aimed to identify concordance among rhinologists regarding the importance of examination findings for various nasal pathologies. A consortium of 19 expert rhinologists across the United States was asked to rank the importance of findings on nasal endoscopy for 5 different sinonasal symptom presentations. An online questionnaire was distributed in July 2023. The questionnaire utilized JotForm® software and featured 5 cases with a set of 4 identical questions per case, each covering a common indication for nasal endoscopy. Rankings were synthesized into Normalized Attention Scores (NASs) and Weighted Normalized Attention Scores (W-NASs) to represent the perceived importance of each feature, scaled from 0 to 1. General concordance was found for examination findings on nasal endoscopy within each case. The perceived features of importance differed between cases based on clinical presentation. For instance, in evaluating postnasal drip, the middle meatus was selected as the most important structure to examine (NAS, 0.73), with mucus selected as the most important abnormal finding (W-NAS, 0.66). The primary feature of interest for mucus was whether it was purulent or not (W-NAS, 0.67). Similar analyses were performed for features in each case. The implicit framework existing among rhinologists may help standardize examinations and improve diagnostic accuracy, augment the instruction of trainees, and inform the development of artificially intelligent algorithms to enhance clinical decision-making during nasal endoscopy.

Pleomorphic Adenoma in the Nasal Cavity: Case Report and Review of Literature.

Pleomorphic adenoma (PA) represents the most frequently occurring benign tumor within both major and minor salivary glands. However, in rare instances, nasal PA is an epithelial-derived borderline tumor, often originating from the nasal septum. Diagnosis usually relies on histopathological analysis. Under general anesthesia, these rare nasal tumors can be completely resected via endoscopic surgery. This article reports a case of PA originating from the nasal septum in a 49-year-old patient presenting with nasal congestion, along with a brief review of the current literature. The diagnostic nasal endoscopic examination showed a pink neoplastic mass in the left nasal cavity. Subsequent radiologic examination demonstrated a soft tissue mass in the anterior part of the nasal septum. After complete resection under nasal endoscopy, histopathological examination confirmed it as PA. Fortunately, no related complications occurred perioperatively and postoperatively. After surgery, performing a thorough examination with nasal endoscopy and scheduling regular follow-ups are crucial steps to prevent local recurrence.

Manifestation and associated factors of systemic and local allergy among patients with allergic fungal rhinosinusitis: An observational study.

Allergic fungal rhinosinusitis (AFRS) is a subtype of chronic rhinosinusitis, characterized by excessive immune responses to environmental molds or fungi. The diagnosis and classification of AFRS into systemic and local types remain clinically challenging due to overlapping characteristics. This study investigated the prevalence of AFRS, its manifestation and associated factors in systemic and local AFRS. A total of 200 patients diagnosed with fungal rhinosinusitis underwent both skin provocation tests (SPT) and nasal provocation tests (NPT) to confirm AFRS and classify systemic and local types. Patients were considered to have AFRS if either the SPT or NPT was positive. Among these, patients with systemic AFRS were those who had a SPT positive. Local AFRS was when patients had a negative SPT and a positive NPT. Medical history, serum total IgE level, nasal endoscopy examinations, and CT scans were also recorded. Most patients were female (65.8%), with a mean age of 55.6 years (SD = 14.4). Based on the SPT and NPT results, 31% of patients (n = 62) were diagnosed with AFRS. Among these, 54.8% (n = 34) had systemic AFRS, while 45.2% (n = 28) had local AFRS. Patients with AFRS exhibited significantly higher levels of total IgE, eosinophils, and more pronounced signs and symptoms compared to those without AFRS. However, no statistically significant differences were observed between patients with systemic AFRS and those with local AFRS. AFRS was prevalent in our study. Among patients with AFRS, both systemic AFRS and local AFRS were also prevalent. While allergic indicators and clinical presentations can aid in AFRS diagnosis, minimal distinctions were observed between systemic and local AFRS. A comprehensive assessment incorporating both local and systemic allergic responses through provocation tests, such as a combination of skin and nasal tests, is imperative for optimizing AFRS diagnosis and management.

Clinical efficacy and safety evaluation of Dermatophagoides farinae drops in the treatment of allergic rhinitis with epistaxis.

Background. Epistaxis is frequently observed in allergic rhinitis (AR) patients. However, few studies focus on the outcome of epistaxis with treatment of AR patients. This study aimed to retrospectively analyze the efficacy and safety of AR patients with epistaxis treated with sublingual immunotherapy (SLIT). Methods. A total of 74 patients aged 4-60 years with house dust mite (HDM)-induced AR accompanied by epistaxis and who completed 1 year of SLIT treatment with standard Dermatophagoides farinae (D. farinae) drops were enrolled in this study. The symptom scores, total medication scores (TMS), combined symptom and medication score (CSMS), visual analog scales (VAS), and bleeding score (BS) were assessed, as well as the nasal endoscopic examinations were performed to observe nasal signs. Results. The levels of symptom scores, TMS, CSMS, VAS, and BS at 0.5 year and 1 year of SLIT treatment were significantly lower than those at the baseline (all p less than 0.01). Also, statistical differences were seen in CSMS (p less than 0.05) and VAS (p less than 0.01) between 0.5 year and 1 year. As expected, BS was positively correlated with CSMS (r = 0.617, 95% CI 0.517-0.699) and VAS (r = 0.777, 95% CI 0.719-0.822) at all three time points. Conclusions. SLIT with D. farinae drops was effective and safe for AR patients with epistaxis, resulting in improving the symptoms of rhinitis while relieving the symptoms of epistaxis.

Accessory Ostium of the Maxillary Sinus and Its Impact on Sinusitis

Background: One of the anatomical variations in the maxillary sinus is the accessory ostium (AO). In the nasal cavity, the lateral wall’s vertical plane is parallel to the form of the AO, which is round or oval in appearance. During a nasal endoscopic examination, AO may be seen in contrast to the normal ostium of the maxillary sinus, which is hidden behind the uncinate process. Methods: The search for recent research articles on AO of the maxillary sinus was done with databases Scopus, PubMed, Medline, and Google Scholar. This review article discusses the prevalence, development, endoscopic examination, clinical significance, surgical importance, relationship with chronic sinusitis, and its management. Results: AO may interfere with ventilation and drainage of the maxillary sinus. Hence, it is important to evaluate the anatomical features of the AO for its relationship with sinus pathology. The development of maxillary sinusitis may be significantly impacted by the anatomical variance known as AO of the maxillary sinus. The middle meatus’s posterior nasal fontanelle is where AO is most frequently observed. The possible mechanism for the formation of AO is obstruction of the natural ostium of the maxillary sinus by sinusitis or due to anatomical and pathological factors in the middle meatus leading to rupture of membranous regions such as fontanelle. Conclusion: Clinicians must have adequate knowledge regarding the anatomical variations of the AO. It frequently appears in the fontanelle, the membranous portion of the middle meatus’ lateral nasal wall that is between the uncinate process and inferior meatus.

Efficacy of endoscopic sinus surgery in management of odontogenic maxillary sinusitis after control of dental pathology

BackgroundOdontogenic sinusitis (ODS) has clinical features like rhinogenic sinusitis. Although it is usually unilateral, diagnostic overlap could happen. However, ODS necessitates different management which includes dental intervention to eliminate the dental infection source. In some patients, ODS may persist even after management of dental pathology. The aim of this study was to assess the clinical features, and diagnostic criteria of ODS that is persistent after management of dental pathology, and to evaluate the efficacy of endoscopic sinus surgery (ESS) as a therapeutic option of the disease.MethodsTwenty patients were included in this study. All patients were presented with ODS refractory to medical treatment after management of their dental problems. Clinical features of the patients were analyzed. Also, endoscopic nasal examination and computed tomography of paranasal sinuses (CT) were performed for all patients. ESS were used, with widening of the maxillary ostium for drainage. Follow-up was carried out for at least 6 months.ResultsAll patients had unilateral disease, with 3 main complaints: malodourous nasal discharge (90%), facial pain (75%), and nasal obstruction (45%). Endoscopic nasal examination showed either middle meatal purulence (70%) or polypoid mucosa (30%). CT showed either thickened maxillary sinus mucosa (50%), or complete maxillary opacity (50%) with retained foreign body in 2 patients (10%). After ESS, all patients reported relieve of their sinonasal symptoms, and nasal endoscopy showed patent middle meatus, with one patient demonstrated adhesions between the middle turbinate and lateral nasal wall which was asymptomatic.ConclusionPrior dental intervention is a suspicious diagnostic landmark for ODS, and unilateral foul nasal discharge is the main prevalent complaint. Nasal endoscopy usually shows purulence or polypoid mucosa in the middle meatus, and CT is a good diagnostic tool for ODS. ESS with good widening of the maxillary ostium is an effective therapeutic option for those patients.

Relationship between bleeding sites and clinical data: experience of 646 epistaxis cases in 8years.

This study aims to investigate the bleeding sites and their relationship with clinical characteristics in hospitalized epistaxis patients. We retrospectively reviewed the data of 646 hospitalized epistaxis patients. The bleeding sites were identified in 395 (61.1%) patients and unidentified in 251 (38.9%). We found that age > 50years (P = 0.030) and the history of cardiovascular diseases (P = 0.027) were more frequent in patients with unidentified bleeding sites. Among patients with identified sites, inferior meatus (n = 130, 32.9%) was the most common site, followed by the septal surface of the olfactory region (n = 102, 25.8%), nasal septum (n = 80, 20.3%), middle meatus (n = 60, 15.2%), and others (n = 23, 5.8%). After dividing patients into five groups by the area of the bleeding sites, we found significant differences in age (P = 0.026), history of hypertension (P = 0.001), cardiovascular diseases (P = 0.032), and nasal packing (P = 0.011). The logistic regression also revealed that these four factors were predictors for different bleeding sites. The bleeding sites can be identified in most epistaxis patients. Age > 50years and the history of cardiovascular diseases are more frequent in patients with unidentified bleeding sites. In our patients, the most common bleeding site is inferior meatus, followed by the septal surface of the olfactory region, nasal septum, and middle meatus. Age, histories of hypertension, cardiovascular diseases, and nasal packing are factors associated with the bleeding risks of different bleeding sites. According to the different clinical characteristics of patients, the order of the nasal endoscopic examination should be adjusted to develop their treatment plans.

Unveiling the Rarity: A Fascinating Case of Chondro-Osseous Respiratory Epithelial Adenomatoid Hamartoma (COREAH) in the Sinonasal Tract.

Chondro-osseous respiratory adenomatoid hamartoma (COREAH) are extremely rare benign lesions of the sinonasal tract. It is present in 3 to 83-year-olds. It originates from various sites of the sinonasal tract; the most common site is the posterior lateral wall of the nasal cavity. Imaging calcification is an important finding in COREAH. In this case report, we present an exceptionally rare occurrence involving a 55-year-old female patient who exhibited symptoms of nasal obstruction, bleeding from the left side of the nasal cavity and loss of smell. We aim to share our experience in managing this unique condition. Diagnostic nasal endoscopic examination of the patient revealed a reddish, fleshy polypoidal mass in the left nasal cavity arising from the lateral wall of the left nasal cavity posteriorly and extending anteriorly into the left nasal cavity. The patient underwent an excisional biopsy. Upon microscopic examination, we observed a hamartomatous proliferation of respiratory-type glands exhibiting mucinous metaplasia. Additionally, numerous spicules of mature bone were present, a distinctive feature of COREAH. The patient underwent a 6-month follow-up, during which no recurrent growth was detected within the nasal cavity.

Fascia Lata-Fat Island Graft in Septal Perforation Repair.

Objective: To measure the success of the fascia lata-fat island graft technique in septal perforation repair as measured by nasal endoscopic examination. Background: This study presents the results of using fascia lata-fat island, a different graft technique, for the repair of septal perforations, offering an alternative to this challenging procedure. Methods: This retrospective study assesses nasal septal perforation repair using the fascia lata-fat island graft technique performed by a single surgeon. Inclusion criteria involved completing 12-month follow-ups within a 3-year review period. Success rates were calculated and evaluated alongside patient characteristics. Results: The median (range) age of the 25 patients included in the study was 34 (25-45) years and 72.0% were men. The septal perforation size of all patients was >2 cm and the etiological cause in all of them was previous septal surgery. All patients were followed for 12 months. The perforation was completely closed in 23 of 25 patients (92%). Conclusion: Using a different graft with an open rhinoplasty approach, we achieved a high success rate in patients with large septal perforations, followed for 1 month with nasal stenting and an average follow-up duration of 12 months.

Acute and chronic rhinosinusitis age characteristics

Children's and adults' rhinosinusitis are two diseases that have both similarities and differences in anatomy, epidemiology, causes, pathogenesis, diagnosis and treatment. At the same rhinosinusitis is one of the most common in otorhinolaryngology's practice, both in children and adults. The of adults paranasal sinuses (PNS) anatomy differs from children's PNS anatomy. Although ostiomeatal complex occlusion is recognized as a major cause of poor ventilation and drainage of the adult paranasal sinuses, it does not have a strong effect on pediatric rhinosinusitis, but adenoids play a key role. Adenoids are bacteria and biofilms reservoirs that cause chronic refractory rhinosinusitis regardless of pharyngeal tonsil size. The prevalence of chronic rhinosinusitis (CRS) is lower in children than in adults. Diagnosis of children's rhinosinusitis is more difficult because nasal cavity endoscopic examination is performed rarely due to the occasional need of general anesthesia during the procedure. Moreover, it's necessary to take into account prevailing etiological role of viruses in ARS at children's age and chronic adenoiditis often accompanies pediatric CRS, which requires attention prescribing medical therapy as the basis of rhinosinusitis treatment. The DysheLORz based on Pelargonium sidoides roots is highly effective and safe for children's and adults ARS and CRS treatment, both as monotherapy and in combination with topical steroids and antibiotics. This herbal medicine immunomodulatory effect is mediated mainly by stimulating the production of TNF-α, IL-1, IL-12 and IFN-γ. It activates macrophages and improves their phagocytic activity. IL-12, together with TNF-α, enhances NK and cytotoxic CD8+ lymphocytes' activity against infected cells. IL-12 effect on Th1 lymphocytes maturation provides a link between innate and adaptive immunity. This is also increasing MCP-1, IP-10 and MIP-1β chemokines synthesis and decreasing MIP-1α, ENA-78, GROα and IL-8 production in PNS and nasal mucosa. This leads to decrease of neutrophils chemotaxis to the inflammation site, and decline of serine proteases concentration (neutrophils main enzymes), that increases mucous membrane epithelial barrier permeability, reducing bacterial infections risk. Additionally, Pelargonium sidoides increases epithelial cells beating cilia frequency and inhibits hemagglutinin and neuraminidase present on influenza virus surface. The drug increases antimicrobial peptides production as defensins, human neutrophil peptides (HNP) and bactericidal permeability-increasing protein (BPI), which is also important for rapid inflammation regression in rhinosinusitis. It causes bacterial adhesion to epithelial cells inhibition, phagocytosis stimulation, nitric oxide (NO) release and oxidative burst. The medicine had a direct effect on Streptococcus pneumoniae, Staphylococcus aureus, Neisseria, Moraxella catarrhalis and Haemophilus influenza. Based on these data, it is possible to explain the high effectiveness and safety of the drugs based on Pelargonium sidoides in ENT organs inflammation treatment, for both adults and children over 1 year old.

Reliability of nasofibroscopy for the evaluation of adenoid hypertrophy and its correlation with clinical symptoms

ObjectiveTo analyze the reliability of estimating the percentage of rhinopharyngeal obstruction by the adenoid using nasofibroscopy and its correlation with clinical symptoms. MethodsCross-sectional observational study was conducted, involving 80 patients between 4 and 14 years old, recruited from Santa Casa of São Paulo general otorhinolaryngology outpatient service during the years of 2020 and 2021. All patients underwent nasal endoscopy examination, and the recorded videos were randomly assigned to four evaluators in two different sessions, with a minimum interval of 1 month. The evaluators estimated the percentage of rhinopharyngeal obstruction caused by the adenoid. Intra- and inter-evaluator correlations were established by comparing the reports from each evaluator. The data were compared to the Pro Image J Software report, that also estimates a percentage of obstruction by computer graphics. To correlate the grading of obstruction with clinical symptoms, all patients completed the OSA (Obstructive Sleep Apnea) 18 questionnaire, a validated tool for assessing sleep apnea in children. The questionnaire data were then compared to the average scores assigned by the evaluators. ResultsSatisfactory intra- and inter-rater correlations were observed, and the results were consistent with the Pro Image J Software. However, no correlation was found between the percentage of obstruction and the severity of clinical symptoms. ConclusionNasofibroscopy demonstrates good reliability in assessing a percentage of rhinopharyngeal obstruction caused by adenoids. However, there is no correlation between the degree of obstruction of the rhinopharynx and the clinical symptoms. Level of evidence4.

Seeing Voices: A Dynamic, Interprofessional Approach to Teaching Performing Arts and Speech-Language Pathology Students About Vocal Anatomy and Physiology

Seeing Voices was an interprofessional, technology-enabled, large-scale, teaching and learning event developed to address the need to improve voice students' knowledge of laryngeal anatomy and physiology toward understanding and maintaining vocal health. Seeing Voices trialed a novel interprofessional educational approach, collected both quantitative and qualitative data about student experiences of laryngostroboscopic examination, and built a databank of laryngeal recordings for future student learning. Seeing Voices involved two 3-hour seminars in a large, university lecture space, run by an interprofessional team (speech-language pathologists, vocal coach, Ear Nose and Throat consultant) with quality equipment projecting laryngeal images to large screens with expert commentary in real time. Participants were 18 students who volunteered for laryngeal examination (9 per seminar) and student attendees (n=175) from performing arts courses (classical singing, contemporary, jazz, musical theater, acting) and a speech-language pathology course. A quantitative evaluation of knowledge gained was undertaken using a Qualtrics survey. Results from pre (n=175; performing arts=120; speech-language pathology (SLP)=55) and postevent (n=99; performing arts=56; SLP=43) questionnaires were received from the students who attended. Interviews were collected from 15 of the 18 student volunteers about their experiences of nasendoscopic evaluation and data were analyzed using qualitative description and qualitative content analysis. Quantitative results demonstrated a strong trend toward increased knowledge following attendance at the event across year cohorts for both student groups. Qualitative interviews highlighted the value in seeing multiple examples of normal laryngeal functioning across different vocal techniques in real time. For those undertaking nasendoscopic examination, simultaneously seeing and feeling laryngeal maneuvers used in training appeared to promote understanding of their own vocal mechanism and the purpose of different vocal techniques. Seeing Voices offers a novel way to improve interprofessional collaboration, and engagement with, and understanding of, laryngeal anatomy and vocal health by students in performing arts and speech-language pathology courses.

Imaging of pharyngeal pathology: A pictorial review.

The pharynx plays a significant role in swallowing and speech, and this is reflected in both its complex anatomy and degree of physiological motility. Patients who present with pharynx-related symptoms such as sore throat, globus, dysphagia or dysphonia will usually undergo visual and nasal endoscopic examination first. Imaging is frequently required to supplement clinical assessment and this typically involves MRI and CT. However, fluoroscopy, ultrasound and radionuclide imaging are of value in several clinical situations. The aforementioned complexity of the pharynx and the myriad of pathologies which may arise within it often make radiological evaluation challenging. In this pictorial review, we aim to provide a brief overview of cross-sectional pharyngeal anatomy and present the radiological features of a variety of pharyngeal pathologies, both benign and malignant.

Augmented Virtual Examination for Cosmetic and Functional Rhinoplasty.

Background: Few studies have critically evaluated the quality of data obtained during telemedical evaluations of patients with nasal complaints. Objective: To compare the quality of data provided by remote endoscopic and external nasal examination with those by in-person evaluations for rhinoplasty and functional nasal surgery, measured by detectability of anatomic features, and to assess associated patient experience measured by reported ease, discomfort, and likelihood of peer recommendation. Materials and Methods: Twenty healthy subjects performed a nasal self-examination using an endoscope and webcam under remote videoconferencing service (VCS) guidance. They subsequently underwent in-person examination and were surveyed about their experience. Inter-rater reliability was calculated using kappa coefficients. Detectability of anatomic features by in-person versus virtual examination was compared using Wilcoxon and chi-square tests. Results: Median subject age was 27.5 years (range 23-77). Kappa coefficients were 0.78 for in-person and 0.66 for virtual evaluations. Only the internal nasal valve and inferior turbinate were better visualized in person. There were no differences between detectability of external features on in-person versus virtual examinations. Subjects' average likelihood of recommending this technology (1-10) was 8.65 (SD 1.4). Conclusions: Intranasal examination by physician-guided remote endoscopy and webcam-based facial analysis demonstrate nasal anatomy comparable with in-person evaluation and anterior rhinoscopy.

Sphenochoanal polyp in a child presented with recurrent middle ear effusion: a case report

BackgroundSphenochoanal is a rare benign sinu-nasal lesion. It arises from the sphenoid sinus and passes to the choana then to the nasopharynx. It usually presents with nasal obstruction, discharge, snoring, and headache. It has been reported—only once in the English literature—to cause Eustachian tube dysfunction and middle ear effusion (MEE) in an adult male. In this report, we described an 8-year-old child with a sphenochoanal polyp presented with MEE.Case presentationAn 8-year-old boy was referred to us by his family physician with recurrent earache. Otoscopic examination showed MEE on the left side. Anterior rhinoscopy showed a thick grayish discharge in the left nasal cavity. Nasal endoscopic examination showed a polyp in the posterior part of the left nasal cavity obstructing the choana. Computed tomography revealed soft tissue density on the left sphenoid sinus extended to the choana and nasopharynx. Diagnosis of sphenochoanal polyp was established. Endoscopic sinus surgery with removal of the lesion and ventilation tube insertion in the left ear was performed. Histopathologic examination confirmed that the polyp was inflammatory. Follow-up for 1 year showed no recurrence.ConclusionsSphenochoanal which is a rare lesion in children could be a cause of Eustachian tube dysfunction and MEE. Nasal endoscopy and computed tomography are important for diagnosis. We recommend to list sphenochoanal polyp as a cause of Eustachian tube dysfunction and recurrent MEE in children.

Importance of S-point in the Management of Severe Epistaxis

Although severe epistaxis is uncommon, it is serious. The systematic endoscopic nasal examination is an essential step in identifying the bleeding point and aiding electrocauterization. Currently, the S-point, which is located in the superior part of the nasal septum behind the septal body and corresponding to the axilla of the middle concha, is identified in about 30% of cases with severe epistaxis. Cauterization of this point has an excellent rate of controlling the bleeding and preventing its recurrence. We aimed to highlight the significance of the S-point in the management of severe cases of epistaxis.

Clinical and Imaging Evaluation of COVID-19-Related Olfactory Dysfunction.

Olfactory dysfunction has been reported in 47.85% of COVID patients. It can be broadly categorized into conductive or sensorineural olfactory loss. Conductive loss occurs due to impaired nasal air flow, while sensorineural loss implies dysfunction of the olfactory epithelium or central olfactory pathways. The aim of this study was to analyze the clinical and imaging findings in patients with COVID-related olfactory dysfunction. Additionally, the study aimed to investigate the possible mechanisms of COVID-related olfactory dysfunction. The study included 110 patients with post-COVID-19 olfactory dysfunction, and a control group of 50 COVID-negative subjects with normal olfactory function. Endoscopic nasal examination was performed for all participants with special focus on the olfactory cleft. Smell testing was performed for all participants by using a smell diskettes test. Olfactory pathway magnetic resonance imaging (MRI) was done to assess the condition of the olfactory cleft and the dimensions and volume of the olfactory bulb. Olfactory dysfunction was not associated with nasal symptoms in 51.8% of patients. MRI showed significantly increased olfactory bulb dimensions and volume competed to controls. Additionally, it revealed olfactory cleft edema in 57.3% of patients. On the other hand, radiological evidence of sinusitis was detected in only 15.5% of patients. The average olfactory bulb volumes were significantly higher in the patients' group compared to the control group, indicating significant edema and swelling in the olfactory bulb in patients with COVID-related olfactory dysfunction. Furthermore, in most patients, no sinonasal symptoms such as nasal congestion or rhinorrhea were reported, and similarly, no radiological evidence of sinusitis was detected. Consequently, the most probable mechanism of COVID-related olfactory dysfunction is sensorineural loss through virus spread and damage to the olfactory epithelium and pathways.

Bilateral antrochoanal polyp: a case report of an extremely rare entity managed conservatively with a review from the past 26 years

We report a rare case of a middle-aged man presenting with nasal obstruction, rhinorrhea, and sleeping disturbances, eventually diagnosed with bilateral ACPs. After confirming the diagnosis with imaging and biopsy studies, the patient was treated conservatively, with marked improvements in his symptoms during 2-3 months of regular follow-ups. A review of the relevant literature regarding the presentation, diagnosis, and outcome of this rare entity is presented, highlighting its controversial etiopathogenesis. Presenting symptoms of ACP in most cases is unilateral progressive nasal obstruction. The occurrence of ACP bilaterally is rarely encountered in clinical practice. Diagnosis is mainly clinical and is achievable via nasal endoscopic examination and supported by computed tomography imaging. Treatment remains to be surgical, with 2 years of regular follow-ups being advised to detect any recurrence. This case report adds to the scarce data pool on bilateral ACPs and highlights the necessity of prudent and timely diagnosis of this uncommon entity to avoid unnecessary investigations and lengthy medical or surgical treatment. Additionally, a trial of medical therapy may provide symptomatic relief for patients who do not qualify for surgery.

Endoscopic Grading, Radiological Grading and Clinical Features in Children with Chronic Adenoid Hypertrophy: A Correlational Study.

To obtain a correlation between endoscopic findings, radiological findings and clinical features in children with symptomatic Chronic Adenoid hypertrophy. A cross sectional study was conducted in 42 pediatric patients (3-14years) who visited the Department of Otorhinolaryngology in a tertiary care centre from November 2019 to April 2021 (18months). The patients were subjected to complete history taking; ENT examination, Rigid nasal endoscopic examination, a lateral X-ray nasopharynx were performed prior to surgery after obtaining consent from the parents of the patients. The endoscopic findings were assessed using ACE grading system and the X-ray nasopharynx was assessed using Adenoid- Nasopharyngeal ratio. A male predominance was noted with mouth breathing, snoring, nasal obstruction and recurrent rhinitis as common presentation. Grade 3 hypertrophy was the most common finding in X-ray Nasopharynx (Mean ANR-0.682). Children with Grade 3 adenoid hypertrophy with more than 50% choanal obstruction and Eustachian tube abutment in nasal endoscopy were noted to be the most symptomatic clinically. A positive correlation between reduced hearing (p value-0.004) and blocked ear sensation (p value- < 0.01) with eustachian tube abutment was noted. The children with more symptoms did not show higher-grade adenoid hypertrophy radiographically in our study. The adenoid- nasopharyngeal ratio on X-ray correlated with endoscopic grading of adenoid hypertrophy (p value-0.006) and degree of choanal obstruction (p value-0.003) but not with the abutment of the eustachian tube. The endoscopic grading correlated with clinical grading, but not the X-ray grading. Hence, endoscopic grading appears to be more accurate in assessing the adenoid size and endoscopic grading is nearer to clinical grading than X-ray grading. Though, the digital X-ray nasopharynx lateral view is a more convenient method, nasal endoscopy is the gold standard method to determine whether the adenoid hypertrophy is clinically significant or not.

Acute Vision Loss in Patients With Allergic Fungal Rhinosinusitis: A Case Series

Allergic fungal rhinosinusitis (AFRS) is a subtype of chronic noninvasive sinusitis accounting for 7.8% (0.2%-26.7%) of all chronic rhinosinusitis cases. A definitive diagnosis is usually made after sinus surgery. Successful treatment requires a combination of surgical and medical management. Although orbital involvement is relatively common, reports on optic neuropathy and acute vision loss are limited. Herein, we present a series of 3 patients with AFRS who presented with acute visual loss as the chief complaint. All 3 patients were otherwise healthy adults in their early 20s with extensive nasal polyps on endoscopic nasal examination and bone erosion in the bilateral orbits and lateral wall of the sphenoid sinus on the affected side on imaging. One of the 3 patients had bilateral cranial nerve IV defects in addition to cranial nerve III defects. All patients underwent endoscopic sinus surgery with orbital decompression and were followed up postoperatively by both otolaryngology and ophthalmology services with endoscopic and radiologic evaluation. Unfortunately, no meaningful improvement in vision was observed in any patient despite successful nerve decompression. Prompt diagnosis and early medical and surgical intervention are warranted to prevent complications in patients with AFRS with orbital extension.
