Endoscopic Assessment of Cholesteatoma Following Microscope Assisted Tympano: Mastoidectomy: Study design: a cross section descriptive study.

Complete surgical removal of cholesteatoma has been traditionally performed by microscopic approaches. In recent years, use of endoscopes in middle ear surgery is gaining increasing importance. The wide field view offered by the endoscopes in comparison to the narrow field of view of the binocular microscope enables a surgeon to see and dissect around corners, thereby exposing 'hidden recesses' of the middle ear which can be useful during cholesteatoma surgery. To identify remnant cholesteatoma in difficult access sites of the middle ear cleft using endoscopes following a microscope assisted mastoidectomy. A cross sectional study was conducted in patients who were clinically diagnosed with cholesteatoma. Patients were subjected to High Resolution Computed Tomography of the temporal bone and pre-operative audiological tests. Mastoid exploration was performed microscopically followed by endoscopic evaluation and clearance of disease in the same setting. Patients were then followed up post-operative and endoscopically evaluated to look for any remnant disease. A total of 45 patients were included, all of which underwent microscopic assisted mastoidectomy. Remnant cholesteatoma was discovered in 15 out of 45 cases (33%) distributed in the hidden areas; in the region of sinus tympani 9(60%), anterior epitympanum 4(27%), hypotympanum 1(7%) and tip Cells 1(7%). It can be concluded that endoscopes have a definite role in evaluation and complete surgical clearance of cholesteatoma particularly from the hidden areas of middle ear cleft which would have otherwise been missed by the straight line view of a microscope thereby grossly reducing the rate of remnant disease.

Alveolar Rhabdomyosarcoma of the Temporal Region with Metastatic Cervical Lymph Node.

Introduction: Paediatric rhabdomyosarcoma most commonly occurs in the head and neck region. Its treatment is complex, including multi-drug chemotherapy, surgery and radiotherapy. Case report: Here, we report a case of alveolar rhabdomyosarcoma of the temporal region with a metastatic cervical lymph node, in a 15-year-old girl, and its management. The patient received ne-adjuvant chemotherapy, followed by surgery and post operative radiotherapy. Literature was also reviewed for the various treatment modalities for these rare tumours. Discussion: Rhabdomyosarcoma of the temporal region has rarely been reported in the literature. Due to the rarity of these tumours, there are difficulties in creating standardized therapeutic protocols. However, multimodality treatment, including chemotherapy, surgery and radiotherapy, has been shown to improve the overall survival rate.

Sentinel ear bleed as a presenting sign for carotid artery blowout due to aspergillus abscess in parapharyngeal space in an immunocompetent infant.

Parapharyngeal abscesses leading to complications, although rare after the advent of antibiotics, can lead to serious complications. One such complication is carotid erosion that can lead to a potentially fatal carotid artery blowout. We report a case of a previously healthy infant who presented with fever, ear bleed and progressively increasing swelling in the right side of his neck that led to airway compromise. The child required immediate securing of the airway at presentation. Imaging revealed lobulated abscess with multiple bleeding points eroding the carotid vessels, along with internal jugular venous thrombus. Surgical exploration was done and abscess debulked. Histopathology revealed aspergillus, which was treated with antifungals. He was discharged on oral warfarin after 40 days of hospital stay and remains well on follow-up. Sentinel ear bleed warrants close observation for possibility of carotid artery blowout in children with parapharyngeal abscesses.

Sarcomatoid Carcinoma of Larynx: A Rare Case.

Sarcomatoid carcinoma is a rare tumour consisting of both sarcomatous and carcinomatous elements. It accounts for less than 1% of laryngeal malignancies. This case report describes sarcomatoid carcinoma of the larynx in a 54-year-old male managed by total laryngectomy with post operative radiotherapy. Surgery is the treatment modality of choice for this rare entity. However, early stage sarcomatoid carcinoma tumours are better treated with radiotherapy alone similar to early stage squamous cell carcinoma of the larynx with favourable results.

Sinonasal Inflammation or Neoplasm: Raise the Red Flagsǃ-A Pictorial Review.

Inflammatory pathology remains the most common indication for sinonasal imaging. However, sinonasal region is also the epicenter of a variety of neoplasms. These are often missed both clinically and radiologically owing to nonspecific signs and symptoms and subtle imaging pointers. An early diagnosis of sinonasal neoplasms is critical for timely management and hence better prognosis and survival rate. This pictorial review aims to acquaint the reader with the "red flag" signs on computed tomography that should raise suspicion for an underlying neoplastic pathology and also highlights the imaging features of common sinonasal neoplasms.

Acceptance of Endoscopes in Otology - An Indian Perspective and Review of the Literature.

Introduction The role of endoscopes in the ear, nose, and throat (ENT) field has been described since the 1980s; It started with endoscopic nasal surgeries, followed by otological and laryngological procedures, and, since then, it has experienced a rapid evolution. Endoscopes help otologists understand how to approach difficult areas of middle ear, as well as the physiology of middle ear cleft. Objectives Despite the introduction of endoscopes in the field of otology, microscopes are still widely used in clinics and in operation theaters either alone or with endoscopes. The present study, which was conducted amongst otologists in India, is on their experience with and knowledge of the use of the endoscope compared to microscopes. Methods A Google form-based questionnaire comprising 18 questions was developed and sent online to otologist all over the country. The final dataset included responses from 354 active otologists. Results Out of 354 participants, only 3% had more than 5 years of experience in endoscopic ear surgery (EES), and 16.1% had never worked with an endoscope. Endoscopes were used in clinics and in operation theaters by 74.9% of the participants. Conclusion There has been a rise in the acceptance and use of endoscopes among Indian otologists and otology surgeons in last few decades.

A common tumour in an uncommon region.

Lipomas are benign, slow growing soft tissue neoplasm that present as soft, painless nodules that are most commonly seen on the trunk but can be located anywhere on the body. They are however seldomly encountered within in the parotid region. It's occurrence in this region also makes its surgical resection challenging due to its close relation to the facial nerve and its branches. We report a case of lipoma of the parotid region in a 30-yearold man who had a 5.0 × 3.0 cm soft mass in the right parotid gland which was managed surgically.

Infantile Fibrosarcoma of the Tongue Base.

Infantile fibrosarcoma is an uncommon soft tissue tumour in infants and children mostly located in the extremities. Its occurrence in the head and neck, particularly in the oral cavity is extremely rare. Here, we report a case of infantile fibrosarcoma of the tongue base in a 9-year-old boy and discuss the complexities in arriving at diagnosis and its management. The patient underwent wide local excision of the tumour. Histopathology was essential in confirming the diagnosis. As per search in English literature, this is the first case of infantile fibrosarcoma of the tongue base to be reported till date. Treatment of choice is wide local excision with or without chemotherapy.

Correlation of ultrasound-based TIRADS and the Bethesda system for reporting of thyroid cytopathology: A study in a tertiary care centre.

BACKGROUND: The age-standardised incidence rate of thyroid cancer in India is 1 in 416 in the general population. This increased incidence has mainly been attributed to improved detection methods for small thyroid lesions. Two such methods are the American College of Radiology Thyroid Imaging Reporting and Data System (ACR TIRADS) and the Bethesda System for Reporting Thyroid Cytopathology (TBSRTC). AIMS AND OBJECTIVES: To study the correlation between ACR TIRADS and TBSRTC, and between each system and the final histopathological report. MATERIALS AND METHODS: Thyroid cytopathology cases were retrieved for the period January 2019 to July 2022. For each case, the TIRADS score and Bethesda category were noted. Histopathology specimens were also traced. RESULTS: The study comprised 1100 cases, with 955 female and 145 male patients (M:F = 1:6.59), and ages ranging between 7 and 85 years. The TIRADS scoring was available for 1036 cases. Histopathology was available for 231 cases. There was a significant correlation between TIRADS and TBSRTC, with a p-value of 0.000 and a substantial Kappa agreement of 0.688. Both TIRADS and TBSRTC also had significant correlations with the histopathology data, with a p-value of 0.000 for each. The sensitivity values for TBSRTC and TIRADS were 69.4% and 65.8%; specificity, 99.3% and 96.5%; positive predictive value (PPV), 98.3% and 91.8%; and negative predictive value (NPV) 84.7% and 84.4%, respectively. The risk of malignancy (ROM) was also calculated and was found to be high, especially for TBSRTC II, III, IV and V (11.3%, 20%, 61.5%, 97.4% respectively) and TIRADS 2 and 3 (10.3% and 29.6% respectively). CONCLUSION: The TIRADS and TBSRTC systems of categorisation of thyroid lesions are concordant and could help improve the overall survival rate of patients with thyroid malignancies.

Outcomes of 8 × 8 mm osteotomy in powered external dacryocystorhinostomy.

Purpose: To study the endoscopic ostium characteristics and outcome of 8 × 8 mm osteotomy in external dacryocystorhinostomy (DCR) using the microdrill system. Methods: This prospective interventional pilot study was performed on 40 eyes of 40 patients with primary acquired nasolacrimal duct obstruction (NLDO) from June 2021 to September 2021 in patients undergoing external DCR. An 8 × 8 mm osteotomy was performed using round, cutting burr attached to a microdrill system. Success was defined as patent ostium on lacrimal syringing (anatomical) and a Munk score <3 (functional) at 12 months. Postoperative endoscopic ostium evaluation was done using a modified DCR ostium (DOS) scoring system at 12 months. Results: The mean age of the study participants was 42.41 ± 11.77 years and the male-to-female ratio was 1:4. The mean duration of surgery was 34.15 ± 1.66 minutes and that for osteotomy creation was 2.5 ± 0.69 minutes. The mean intraoperative blood loss was 83.37 ± 11.89 ml. Anatomical and functional success rates were 95% and 85%, respectively. The mean modified DOS score was "excellent" in 34 patients (85%), "good" in 1 patient (2.5%), "fair" in 4 patients (10%), and "poor" in 1 patient (2.5%). Complications included nasal mucosal injury in 10% (4/40) of patients, complete cicatricial closure of ostium in 2.5% (1/40), incomplete cicatricial closure in 10% (4/40), nasal synechiae in 5% (2/40), and canalicular stenosis in 2.5% (1/40). Conclusion: An 8 × 8 mm-sized osteotomy created by powered drill and covered by lacrimal sac-nasal mucosal flap anastomosis in external DCR is an effective technique that has minimal complications and shorter surgical time.

COVID-Associated Sinonasal Mucormycosis: Radiological Pathological Correlation and Prognostic Value of MR Imaging.

Purpose Our aim was to assess the sinonasal magnetic resonance imaging (MRI) features of acute invasive fungal rhinosinusitis (AIFRS) in coronavirus disease (COVID)-associated mucormycosis (CAM) and to correlate these with histopathology and patient outcome in terms of duration of hospital stay and survival at 10 weeks. Methods Twenty patients with histopathologically confirmed sinonasal CAM underwent MRI (including postcontrast T1-weighted and diffusion-weighted imaging). Histopathological findings (presence of coagulative necrosis, granulomatous reaction, and fungal burden) were recorded and all patients were followed up at 6 and 10 weeks. Statistical analysis was done using chi-square test and Fischer's exact test. Results Enhancement patterns seen in our subjects included homogeneous, heterogeneous, and lack of contrast enhancement (LOC), with LOC being the most common (65%). Diffusion restriction was found in 90% patients. Statistically significant correlation was found between LOC pattern and presence of coagulative necrosis ( p -value = 0.007), extent of fungal hyphae ( p -value = 0.047), and duration of hospital stay ( p -value = 0.004). Restricted diffusion was also seen to correlate with a high fungal load ( p -value = 0.007). Conclusion Our study describes the MRI findings of AIFRS in CAM and highlights the imaging features which may be surrogate markers for coagulative necrosis and fungal burden.

MRSA Causing Necrotizing Fasciitis in 18-Month-Old Boy.

Necrotizing fasciitis is a rare and fulminant infection of the superficial fascia and subcutaneous cellular tissue. It is commonly polymicrobial, with the combination of aerobic and anaerobic bacteria, which contributes to the rapid progression and severity of the disease. The microbes commonly involved include group A streptococcus, Enterobacteriaceae, anaerobes, and Staphylococcus aureus. Over the past few years, skin and soft tissue infections, including necrotizing fasciitis, due to methicillin-resistant Staphylococcus aureus are increasing.

Osteosarcoma of the jaw: Primary versus secondary - A report of two cases.

ABSTRACT: Osteosarcoma (OS) is the most common primary malignancy of bone excluding hematological malignancies. Most common sites of tumor are long bones of extremities. OS of the jaw are extremely rare with mandible being more commonly after than maxilla. Hereby, we present two cases of OS of jaw with one patient being male and other female.

A non-invasive miRNA-based approach in early diagnosis and therapeutics of oral cancer.

Oral or mouth cancer is the 16th most common form of cancer among the world's topmost malignancies. Healthy lifestyle and control of known risk factors can reduce its incidences further. Patients succumb to oral cancer when diagnosed late and lack timely access to tertiary care. Molecular biomarkers might help in early detection of oral cancer. Recently, researchers have identified numerous microRNAs which play a crucial role in promoting and suppressing oral cancers. miRNAs are short non-coding RNA molecules (18-22 nucleotides) that play a pivotal role in regulating gene expression. Understanding the miRNA interplays in oral cancers could augment the development of potential diagnostic, prognostic, and therapeutic tools. Liquid biopsy- a non-invasive approach that has been used lately, allows the determination of miRNAs in biological fluids that play essential roles in tumor suppression and cancer promotion. Herein, we summarize an update on the role of miRNAs in the diagnosis and treatment of oral cancer.

Perceived usefulness of trauma audit filters in urban India: a mixed-methods multicentre Delphi study comparing filters from the WHO and low and middle-income countries.

OBJECTIVE: To compare experts' perceived usefulness of audit filters from Ghana, Cameroon, WHO and those locally developed; generate context-appropriate audit filters for trauma care in selected hospitals in urban India; and explore characteristics of audit filters that correlate to perceived usefulness. DESIGN: A mixed-methods approach using a multicentre online Delphi technique. SETTING: Two large tertiary hospitals in urban India. METHODS: Filters were rated on a scale from 1 to 10 in terms of perceived usefulness, with the option to add new filters and comments. The filters were categorised into three groups depending on their origin: low and middle-income countries (LMIC), WHO and New (locally developed), and their scores compared. Significance was determined using Kruskal-Wallis test followed by Wilcoxon rank-sum test. We performed a content analysis of the comments. RESULTS: 26 predefined and 15 new filter suggestions were evaluated. The filters had high usefulness scores (mean overall score 9.01 of 10), with the LMIC filters having significantly higher scores compared with those from WHO and those newly added. Three themes were identified in the content analysis relating to medical relevance, feasibility and specificity. CONCLUSIONS: Audit filters from other LMICs were deemed highly useful in the urban India context. This may indicate that the transferability of defined trauma audit filters between similar contexts is high and that these can provide a starting point when implemented as part of trauma quality improvement programmes in low-resource settings.

Preoperative emobilisation of juvenile nasopharyngeal angiofibroma.

INTRODUCTION: Juvenile nasopharyngeal angiofibroma(JNA) are highly vascular benign tumours originating in the sphenopalatine fossa and may extend to the pterygopalatine fossa, paranasal sinuses, and nasal cavity. The management of JNA has evolved greatly with development of endoscopy. Treatment modality has changed from open approach to endoscopic approach due to various advantages offered by the endoscopic approach. Bleeding during the surgery can compromise the exposure and surgical excision of JNA endoscopically. There have been many techniques to decrease intraoperative bleeding including external carotid ligation, hypotensive anaesthesia and more recently embolization of the feeding vessels. Embolization of the tumour has made the endoscopic excision of JNA easier because of less bleeding. This study was taken to find out the outcomes of surgical excision of JNA after embolization. METHODOLOGY: We retrospectively reviewed 22 histopathological proven JNA cases that underwent preoperative embolization followed by resection during the period of June 2015 to December 2020 in our tertiary care hospital. From the records demographic, clinical, radiological imaging (CECT nose and PNS), angiographic, pre-operative embolization and operative details were evaluated. RESULT: In the present study a total of 22 cases of angiofibroma were taken up for surgical excision after embolization. A complete endonasal endoscopic resection could be done in 21/22 cases with average operative time of 141 minutes (80 minutes-190 minutes range). The mean blood loss during surgery was 1163 ml (Range 500 ml- 1900 ml). In 7/22 (31.81%) subjects required intraoperative blood transfusion. No perioperative surgical complications occurred. CONCLUSION: Endoscopic excision of JNA has now become the primary operative technique and pre operative embolization in such cases can reduce the intraoperative time, blood loss and tumour relapse rate. It is a relatively safe procedure in a hand of an expert and must be done where ever available.

Prevalence of Positive Level IIb Lymph Nodes in Tongue Carcinoma: Experience From a Tertiary Care Center in North India.

Introduction Complications during and after dissection of level IIb lymph nodes include spinal accessory nerve (SAN) dysfunction, which results in the limitation of shoulder movements and, thus, hurts the quality of life. The current study aims to know the occurrence of level IIb lymph node positivity in tongue carcinoma. Methods This cross-sectional study was conducted from January 2019 to December 2019 in a tertiary care center in North India. Adult cases with primary ulcer-proliferative growth over the lateral border of the tongue were included in the study. The level IIb lymph node positivity from the postoperative histopathology report was the primary outcome measure of this study. To investigate the potential association of tumor size on level IIb lymph node positivity, we compared the maximum tumor dimensions among the level IIb lymph node-positive and -negative groups. In addition, to analyze the impact of the tumor's invasive nature on level IIb lymph node positivity, we compared the depth of invasion and proportion of cases with muscle involvement among the level IIb lymph node-positive and -negative groups. Lastly, to investigate their concurrent occurrences, we compared the number of level IIb lymph node-positive cases among the level IIa lymph node-positive and -negative groups. Results A total of 39 patients fulfilling the inclusion criteria were included in the study. Only six had positive level-IIb lymph nodes. No significant associations of tumor size, invasion depth, muscle invasion, or involvement of level IIa lymph nodes with the positivity of level IIb lymph nodes were found. However, only three were level IIb lymph node-positive in 28 level IIa lymph node-negative cases. Conclusion Considering the low risk of isolated level IIb lymph node positivity in level IIa lymph node-negative cases, the dissection of level IIb nodes could be omitted during the surgical excision of the tumor. However, radiological investigations detecting metabolic activity should be used in the preoperative period and postoperative follow-up to detect early lymph node involvement and disease recurrence.

MR imaging spectrum in COVID associated Rhino-Orbito-Cerebral mucormycosis with special emphasis on intracranial disease and impact on patient prognosis.

In the wake of the ongoing Coronavirus Disease 2019 (COVID-19) pandemic, a new epidemic of COVID associated mucormycosis (CAM) emerged in India. Early diagnosis and prompt treatment of this deadly disease are of paramount importance in improving patient survival. MRI is the cornerstone of diagnosis of early extrasinus disease, particularly intracranial complications which have traditionally been associated with a high mortality rate. In this review, we depict the sinonasal, perisinus, orbital and intracranial involvement in CAM. Special emphasis is laid on intracranial disease which is categorized into vascular, parenchymal, meningeal, bony involvement and perineural spread. Vascular complications are the most common form of intracranial involvement. Some unusual yet interesting imaging findings such as nerve abscesses involving the optic, trigeminal and mandibular nerves and long segment vasculitis of the internal carotid artery extending till its cervical segment are also illustrated. In our experience, patient outcome in CAM (survival rate of 88.5%) was better compared to the pre-pandemic era. Presence of intracranial disease also did not affect prognosis as poorly as traditionally expected (survival rate of 82.8%). Involvement of brain parenchyma was the only subset of intracranial involvement that was associated with higher mortality (p value 0.016). The aim of this review is to familiarise the reader with the MR imaging spectrum of CAM with special focus on intracranial complications and a brief account of their impact on patient prognosis in our experience.
