ABSTRACT
Lymphangiomas are congenital benign lesions commonly seen in pediatric age group with a rare occurrence in the region of head and neck, commonly presenting as asymptomatic masses. Cervical lymphangioma is a rare entity among adults, and giant sized lymphangiomas in this region have sparse mention in literature. This case report describes the rare presentation of a giant cervical lymphangioma and the challenges involved to treat such masses in the region of head and neck. We encountered a rare case of a 52 year old female who presented with a 10 × 5 cm swelling in the right posterior triangle of neck swelling since 6 months extending from skull base up till clavicle. Pathological and radiological entities confirmed the lesion as a "giant cervical lymphangioma". Head and neck lymphangiomas are congenital lesions of benign origin. Lymphangiomas have been classified as macrocystic if larger than 2 cm, and microcystic if less than 2 cm. Our description of a macrocystic 10 × 6 cm lesion is hence definitely one of the largest cervical lymphangiomas encountered till date. It's a problematic and arduous plan of treatment for such masses in head and neck with a high chance of recurrence if incompletely removed.
ABSTRACT
Plasmoacanthoma is an extremely rare benign verrucous lesion, with few cases reported in the literature, and it often goes misdiagnosed. An attempt was made to discuss the features and compare them to reduce the diagnostic dilemma in cases of plasmoacanthoma, which mimics squamous cell carcinoma, both for the clinician and pathologist. Written informed consent was obtained from the patient for the case report. Institutional ethical clearance was obtained. A review of the literature was conducted after a PubMed search with the keyword "Plasmoacanthoma" on September 20, 2023. Nine articles were obtained, out of which two were not available. One was excluded since it was on plasma cell cheilitis. Five articles, all of which were in the English language, with a diagnosis of plasmoacanthoma were retrieved for the study. A 70-year-old female presented with an ulcer-exophytic lesion involving the lower lip, mimicking a typical squamous cell carcinoma, for which an edge biopsy of the lesion was taken to confirm. Histopathology revealed it to be plasma cell mucositis. The patient was put on the medical line of management with corticosteroids as per guidelines, with no response. A wedge excision was later done as the patient was not responding to medical therapy, and the final histopathology came out to be "plasmoacanthoma". Due to their close resemblance to malignant lesions and histologically mimicking plasma cell mucositis, such lesions often get misdiagnosed, leading to inadequate management. Various sources of literature related to plasmoacanthoma were compared, and the features and histological findings were tabulated so that if any cases were similar to the present case reports, then we could have other differential diagnoses and work accordingly. Plasmoacanthoma may be present in any age group, and the clinical features may be similar to those of squamous cell carcinoma. PCM and plasmoacanthoma are clinically and histologically mimicking conditions that should be confirmed by excisional biopsy on histopathological examination rather than incisional biopsy to avoid pathological adversity, as seen in our case. IHC with kappa and lambda light chains will help identify clonal plasma cells seen in plasmoacanthoma.
ABSTRACT
Myoepitheliomas are uncommon neoplasms of major and minor salivary glands. These tumours are encapsulated and slow growing in nature and are benign in majority of the cases. The mean age of presentation is 40 years and this entity is rarely reported in younger age groups. Here, we seek to report a rare case of a 10-year-old patient who presented with a swelling below the right ear. Clinical and radiological evaluation revealed a mass in the parotid gland. This patient was treated with a superficial parotidectomy and subsequent histopathological examination revealed it to be a myoepithelioma.
ABSTRACT
Objective measurement of the lumen area demands an intraoperative diagnostic tool to aid on-site decision-making. We present a compliant mechanism-based unfurling actuator assembly integrated with a shaft connected to a motorized encoder to translate torque from the user at the proximal end to the actuator at the distal end. The actuator assembly has flexible arms coiled inside a cylindrical casing that moves radially outward upon actuation. Leveraging 3D printing of flexible materials, the unfurling actuator's four-arm design enables patency measurements in circumferential tracheal stenosis of varying grades. The rotary encoder output is correlated with the radially outward movement of the unfurling arms to estimate the lumen diameter. The measurement stability is analyzed using process control charts; data distribution over ten iterations reveals nearly 100% of process data falls between ±3 sigma (Upper and Lower control limits). Comparing measurements from the tool with direct measurement (vernier caliper) and ImageJ analysis, one-way ANOVA for circular morphology yields no significant differences in diameter p = 0.974 and area measurements p = 0.975.Clinical Relevance- Central airway narrowing reduces the effective lumen area in the tracheal and bronchial segments. Grading the degree of narrowing is often based on a suspicion index. A quick but thorough assessment of the airway caliber is essential in emergent or planned intubation, whether congenital, iatrogenic, or idiopathic tracheal stenosis.

Plasmacytomas are localized monoclonal plasma cell lesions with no evidence of systemic involvement which are divided into solitary bone plasmacytoma (SBP) and extra-medullary plasmacytoma (EMP). The diagnosis of plasmacytomas (PCM) in the oral regions is challenging given the atypical clinical manifestations and low frequency. Here, we report an extremely rare case of plasmacytoma in an elderly male which initially appeared to be arising from the left buccal mucosa on clinical examination but after radiological imaging and intra-operative findings, the epicentre was found to be in the left infratemporal fossa (ITF). The patient underwent en-bloc compartment resection with high clearance of the ITF which proved to be an effective management strategy. It is crucial for the head and neck surgeon to be aware of the solitary bone plasmacytoma in the oral and maxillofacial region in order to identify it early and provide these patients with the best care possible before complications arise.
ABSTRACT
Objectives: To compare pre- and post-operative pure tone audiometric and impedance audiometric analysis following conventional and endoscopic microdebrider assisted adenoidectomy and compare the outcomes. Methods: Patients diagnosed with chronic adenoiditis were divided in groups of 25 each. Patients in the first group underwent conventional curettage adenoidectomy, while those in second group underwent endoscopic microdebrider assisted adenoidectomy. Pre- and post-operative pure tone and impedance audiometry were performed for all patients and outcomes were compared. Results: The endoscopic microdebrider assisted method resulted in significantly better outcomes compared to conventional curettage. Criteria such as hearing threshold (p value 0.004 at second follow-up), peak pressure (p value 0.045 at first follow-up) and tympanogram (p value 0.016) showed that the endoscopic method was better, while peak compliance (p value 0.340 at first follow-up) did not show any significant difference between groups. Conclusions: The endoscopic microdebrider assisted method for adenoidectomy has a definite advantage of better visualisation resulting in better clearance of tissue, leading to enhanced middle ear function compared to conventional curettage.

Actinomycosis is caused by actinomyces israelii, a gram positive nonacid fast, anaerobic, commensal bacterium within the oral cavity. Though it is a commensal in oral cavity, it seldom presents as cervicofacial actinomycosis. But there is limited access to literature proving cervicofacial actinomycosis existence so far. We report a case of 35 year old gentleman who presented with painless progressive neck swelling associated with pain while chewing food. On examination, 3.5*2.5 swelling was noted in right submandibular gland area, radiologically a foreign body was detected in the right submandibular gland. Mass was excised in toto and sent for HPE which revealed submandibular gland actinomycosis. Post operatively, patient was managed with long-term broad-spectrum beta lactams and was on regular follow-up. No evidence of recurrence/ fresh complaints noted till date. Although cervicofacial actinomycosis is rare and dangerous with debilitating complications, timely diagnosis and early intervention with broad spectrum antibiotics and surgical excision (if required) shows promising results with complete eradication of disease leaving no residues.

ABSTRACT
Lateral medullary syndrome/Wallenberg syndrome, is a neurological disorder occurring due to ischemia in the lateral part of medullary oblongata resulting in wide range of symptoms. Dysphagia is usually exhibited in severe and persistent form in LMS. Hence timely intervention is mandatory before the patient further worsens. We describe a case of Lateral medullary syndrome with persisitent dysphagia who was managed successfully with cricopharyngeal myotomy.
ABSTRACT
Obstructive sleep apnoea syndrome (OSAS) is a condition that is characterised by frequent apnoea and hypopnoea attacks occurring during sleep. The blood supply to cochlea and acoustic nerves is from terminal arteries, thereby making them susceptible to hypoxia. To compare the audiological profiles in patients with OSAS according to Apnoea Hypopnoea index (AHI) score. Descriptive study was conducted in 32 patients diagnosed to have OSAS in a tertiary referral centre over two year period. The study group was divided into mild, moderate, severe OSAS based on AHI score. The hearing evaluation was done using pure tone audiogram (PTA) and distortion product otoacoustic emission test (DPOAE). Moderate and severe OSAS participants had elevated thresholds at higher frequencies in PTA (4 kHz, 8 kHz), although this was not statistically significant. We also noticed, absent DPOAE responses at higher frequencies (4 k, 6 k, 8 k), with increase in the severity of OSAS at higher frequency, which was statistically significant (p value < 0.05). This study revealed elevated hearing thresholds at higher frequencies (4 kHz, 8 kHz) in PTA and DPOEA with an increase in the severity of OSAS. All OSAS patients, especially with AHI > 30 should be regularly screened for hearing loss.
ABSTRACT
AIM: To determine the effect of cochlear dose on sensorineural hearing loss in patients with head and neck cancer treated by radiotherapy and chemoradiotherapy. MATERIALS AND METHOD: A two-year longitudinal study was conducted on 130 subjects with various head and neck malignancies who were receiving radiotherapy or chemoradiation. 56 patients received only radiotherapy while 74 patients received concurrent chemoradiation five days a week at a dose of 66-70 Gy. They were categorized as having a radiation dose to the cochlea of <35 Gy, <45 Gy or >45 Gy. Pre- and post-therapy audiological evaluation was done using a Pure-tone audiogram, distortion product otoacoustic emission, and impedence. Hearing thresholds were measured at frequencies up to 16,000 Hz. RESULTS: Out of 130 patients 56 received RT alone and 74 received CTRT. There was statistically significant (p value <0.005) difference in Pure-tone audiometry assessment in both the RT and CTRT groups between subjects who received more than and <45 Gy of radiation to the cochlea. There was no significant difference in distortion product otoacoustic emission assessment between patients who received >45 Gy and <45 Gy radiation to the cochlea. Comparison between subjects who received radiation dose of <35 Gy and >45 Gy revealed significant results in the degree of hearing loss (p value <0.005). CONCLUSION: We observed that patients who received >45 Gy of radiation had more sensorineural hearing loss compared to patients who received <45 Gy. A cochlear dose of <35 Gy is associated with significantly lower hearing loss compared to higher doses. We would like to conclude by emphasizing the importance of regular audiological assessments prior to and post radiotherapy and chemoradiotherapy, with regular follow-ups encouraged over a longer period to improve the quality of life in patients with head and neck malignancy.

ABSTRACT
A man in his 50s presented with a 2-month history of left ear discharge associated with hearing loss and weakness of left half of face since 15 days. The patient had no comorbidities, but he gave history of being treated for COVID-19 pneumonia 2 months ago post which he started experiencing left-sided aural symptoms. Clinical examination of ear revealed a subtotal perforation with multiple granulations in middle ear. Facial nerve examination revealed grade 3 lower motor neuron palsy. The biopsy of the granulations was sent to aid in diagnosis which later confirmed left ear mucormycosis. Otological involvement with facial palsy and sudden sensorineural loss in a patient with prior history of COVID-19 has not been reported until in literature. We try to communicate our experience to bridge the gap in understanding and managing this extremely rare occurrence of mucormycosis in the ear of a patient diagnosed with COVID-19 infection.

OBJECTIVE: This retrospective study was undertaken to assess the outcome of the medical and/or surgical management of patients presenting with clinical features of arytenoid granuloma. METHODS: The records of 53 males and 9 females were reviewed for predisposing factors, types of treatment received and recurrence following the treatment. RESULTS: Most of the patients (48 out of 62, 77.4 per cent) were treated conservatively with medical management and voice therapy, which resulted in complete resolution of arytenoid granuloma in over two-thirds of the patients treated (32 out of 48, 66.6 per cent). Overall, 28 patients (out of 62, 45.1 per cent) required surgery (14 failed medical treatment cases and 14 surgery as first-line treatment cases). Of these, five patients (out of 28, 17.9 per cent) had recurrence, and were managed with revision surgery and concurrent local injection of Botox. CONCLUSION: Anti-reflux medication and voice therapy are effective first-line management options. Pre- and post-surgery adjuvant treatment improves the results of surgery. Local injection of Botox was successful in the treatment of failed surgical cases.

Osteomyelitis is an infection of the bone which is accompanied by bony destruction and sequestrum formation. Osteomyelitis of frontal bone requires us to deal with great caution as it can lead to a great deal of morbidity and mortality. Often when surgical treatment provided, it is radical and leaves behind surgical defect over the frontal bone. We report a case of a 14 year old boy diagnosed with frontal bone osteomyelitis of the left side who was treated using antibiotic loaded bone cement.

ABSTRACT
Otoacariasis is the presence of ticks and mites within the ear canal. Though the coexistence of ticks and humans is known for thousands of years, tick infestation is relatively rare in urban population. The most common presenting symptoms are usually itching, otalgia and a foreign body sensation and less frequent ones are tinnitus and otorrhoea. We report cases of otoacariasis with unusual presentation. A total of 43 cases presented to the ENT clinic in our hospital over a period of three years from 2018 to 2021. We present patients who presented with unusual symptoms of conductive hearing loss, ear bleed, and facial palsy. Total of 6 cases of otoacariasis had unusual presentation. 2 cases presented with lower motor neuron palsy, 1 case with ear bleed, and 3 cases with hearing loss. Otocariasis can present with unusual symptoms of hearing loss, ear bleed or facial palsy and this should be included in the differential diagnosis of a patient with history of close proximity to domestic or wild animals. Detailed examination often reveals the presence of the tick and identification and complete removal along with appropriate medication for associated symptoms often results in complete recovery.
ABSTRACT
PURPOSE: The current in vitro study was conducted to assess the remineralization potential of CPP-ACP and a customized dentifrice (tricalcium-phosphate) on artificial carious lesions using DIAGNOdent. MATERIALS AND METHODS: Fifty-one extracted premolars that satisfied the inclusion criteria were painted using acid-resistant nail varnish. A window of 4 × 4 mm was exposed on the center of the buccal surface of each tooth. After 20 minutes of drying, the baseline reading of enamel specimens was assessed using DIAGNOdent. The teeth were then immersed in a bath of demineralizing solution. An incubation period of 96 hours at 37°C resulted in artificial caries-like lesions on the specimen. Readings of the specimen within the window after demineralization were recorded using DIAGNOdent for all the samples. The specimens were divided into three groups randomly [group I-casein phosphopeptide-amorphous calcium phosphate (CPP-ACP), group II-customized dentifrice, group III-artificial saliva]. Samples were subjected to the daily treatment regimen for a period of 30 days. The samples were evaluated for remineralization by laser fluorescent device (DIAGNOdent) on the 15th and 30th day, respectively. RESULTS: The statistical analysis was done using the Friedman test, Kruskal-Wallis test, Wilcoxon sign rank test, and Mann-Whitney test. The results showed that both CPP-ACP and customized dentifrice showed almost similar remineralization potential but CPP-ACP showed significant remineralization (p < 0.001). CONCLUSION: The DIAGNOdent observation conclusively proves that CPP-ACP and customized dentifrice remineralizes the demineralized tooth samples in vitro with CPP-ACP showing significant remineralization.

ABSTRACT
We conducted a randomized crossover trial to identify whether the use of citrate dialysate (CD) for bicarbonate hemodialysis is beneficial compared to regular acetate dialysate (AD) in terms of adequacy, reuse, and quality of life. Thirty-two stable end-stage renal disease patients on twice-weekly maintenance hemodialysis were randomly assigned to CD or AD fluid in a single-blinded randomized prospective crossover trial of 1-year duration. The primary outcomes studied were the impact of CD in comparison with AD on hemodialysis adequacy, reuse of dialyzer, and quality of life. Secondary outcomes studied were the effect on intradialytic hypotension, acidosis correction, and episodes of symptomatic hypocalcemia. A total number of 28 patients underwent a total of 1456 sessions of hemodialysis with CD over 6 months and 1456 sessions with AD over 6 months. There was a significant increase in dialyzer reuse with the use of CD (P = 0.02). There was no difference in dialyzer adequacy as measured by Single pool Kt/V (spKt/V) (P = 0.840) and urea reduction ratio (%) (P = 0.90). Quality of life did not differ between the two groups. No statistically significant difference was observed in predialysis arterial pH (P = 0.23) serum bicarbonate (0.17) and calcium change (P = 0.16). CD is safe and equally effective as compared to AD. It significantly improves the reuse of dialyzer but it does not offer any added advantage in terms of improvement in hemodialysis adequacy and quality of care.
ABSTRACT
OBJECTIVES: To compare the audiological profiles in postmenopausal women with and without osteoporosis and to study the pattern of hearing loss in osteoporotic patients. MATERIALS AND METHODS: 80 postmenopausal women were evaluated at a tertiary referral center and were divided into normal, osteopenic and osteoporotic based on BMD results. The hearing evaluation was done using PTA, Impedance audiometry and DPOAE and the results were compared between the groups and analyzed. RESULTS: Osteoporotic patients had higher incidence of sensorineural hearing loss than normal and osteopenic patients and the results were statistically significant (Pâ¯≤0.001) on PTA and DPOAE testing. The mean pure tone thresholds were significantly higher in osteoporotic patients in comparison with normal and osteopenic patients. The average hearing loss in osteoporotic patients with sensorineural loss was of mild degree. CONCLUSION: The data reveal that osteoporosis is associated with sensorineural hearing loss in postmenopausal women. The underlying mechanism needs further research but cochlear dysfunction could be an important factor.

Blood brain barrier (BBB) is a dynamic interface, comprising polarized endothelial cells, that separates the brain from the circulatory system. The highly protective nature of this tight junction impairs diagnosis and treatment of brain disorders. In this study, we designed a sub atomic size, near infrared emitting, dual function glutathione gold cluster with high fluorescence yield to facilitate permeability of BBB, for imaging applications and drug delivery. The gold cluster was then modified with Levodopa (l-dopa), to utilize the large amino acid transporter 1 (LAT1) pathways to enhance brain entry. Uptake and permeability of the nanoprobes were demonstrated using an established model of BBB, comprising brain endothelial cells (bEnd.3). The uptake and the clearance of l-dopa modified cluster was faster than the glutathione cluster. l-Dopa modified cluster supports the slow and sustained delivery of a model drug, pilocarpine, to the brain. Results of in vivo imaging and drug release in normal mice hold promise for considering the probe for early diagnosis of brain diseases, when the barrier is not disrupted, and for subsequent drug treatment.
