Schwannoma of Nasopharynx-A Rare Case with A Complex Presentation

Nasopharyngeal tumors are rare, and schwannomas originating from this location are extremely uncommon. Schwannomas are tumors arising from the Schwann cells of peripheral nerve sheath which are neuroectodermal in origin. These are benign, slow growing, well-encapsulated tumors and are mostly seen in the head and neck region. We present a rare case of schwannoma with nasopharynx as its epicenter in an elderly female patient who presented with complaints of hematemesis, bilateral nasal obstruction and stertorous breathing. Diagnostic nasal endoscopy revealed a smooth mucosa covered globular mass occupying bilateral choana. Contrast-enhanced computed tomography of Nose and paranasal sinuses revealed a homogenous mass occupying the entire nasopharynx extending into the nasal and oropharyngeal cavities. The patient underwent Trans-nasal Endoscopic excision under general anesthesia. Nasopharyngeal tumors have a wide range of presentation and a high index of clinical suspicion combined with imaging modalities is required for diagnosis and pre operative planning. Some tumors can cause life-threatening airway obstruction due to delayed presentation and should be managed efficiently and meticulously, with endoscopic excision being a viable approach for cases confined within the nasopharynx.

Site of Tracheostomy and Its Influence on The Surgical Outcome and Quality of Life After Tracheal Resection and Anastomosis in Patients with Tracheal Stenosis

Introduction  With the advances in critical care, the incidence of post intubation tracheal stenosis is increasing. Tracheal resection and anastomosis have been the gold standard for the management of grades III and IV stenosis. Scientific evidence from the literature on the determining factors and outcomes of surgery is not well described. Objective  This study was aimed at determining the influence of tracheostoma site on the surgical outcomes and postoperative quality of life of patients undergoing tracheal resection anastomosis. Methods  Thirteen patients who underwent tracheal resection and anastomosis during a period of 3 years were followed up prospectively for 3 months to determine the degree of improvement in their quality of life postsurgery by comparing the pre and postoperative validated Tamil/vernacular version of RAND SF-36 scores and Medical Research Council (MRC) dyspnea score. Results  As per preoperative computed tomography (CT), the mean length of stenosis was found to be 1.5 cm while the mean length of trachea resected was 4.75 cm. We achieved a decannulation rate of 61.53%. There was an estimated loss of 3.20 +/- 1.90 cm of normal trachea from the lower border of the stenosis until the lower border of the stoma that was lost during resection. Analysis of SF-36 and MRC dyspnea scores revealed significant improvement in the domains of physical function postoperatively in comparison with the preoperative scores ( p  < 0.05). Conclusion  Diligent placement of tracheostomy in an emergency setting with respect to the stenotic segment plays a pivotal role in minimizing the length of the resected segment of normal trachea.

One More Chance to See the World: A Rare Case Report on Sphenoid Mucocele Causing Vision Loss

Mucocele of the sphenoid sinus is one of the rare diseases which an ENT surgeon can encounter in a clinical setup. It can often present as a chronic headache. It can remain undiagnosed unless a symptom due to the compression effect of the mucocele, such as diminution of vision, ophthalmoplegia, or any intracranial complication, occurs. Early diagnosis and emergency surgical intervention are imperative to prevent complications. Although late presentation can have a risk of permanent vision loss, improvement in vision postsurgery does not necessarily depend on the duration of symptoms. Here, we present a rare case scenario where, even after the delayed presentation, the patient had a significant vision improvement postsurgery.

Endoscope-Assisted Removal of Post-Traumatic Orbital Epidermoid Inclusion Cyst: A Useful Adjunct

Orbital epidermoid cysts are uncommon lesions within the bony orbit with varied symptomatology related to both the eye and the sino-nasal system. They are often slow-growing cystic masses which may cause facial asymmetry and visual loss due to pressure symptoms. Cross-sectional imaging such as computed tomography and magnetic resonance imaging are contributory and useful for assessment of the size and actual extent and should be mandatory before planning any surgical intervention. Open approaches and needle aspiration have been traditionally described; however, the use of the rigid nasal endoscope in the intraorbital compartment is a useful adjunct for exploration of the extent of the lesion and for complete surgical clearance. In this report, a 69 years old female with an old post- traumatic orbital epidermoid cyst which was removed completely using an endoscope via transorbital route was presented with the review of literature.

Kaposiform Haemangioendothelioma of the Sublingual Gland in an Adult

Kaposiform haemangioendotheliomas (KHE) are extremely rare, borderline malignant, locally aggressive vascular tumours. KHE is usually found in the retroperitoneum, over the extremities, the soft tissues of the trunk, mediastinum and the head and neck regions. We present a very rare case of KHE of the sublingual gland in an adult, which was not associated with Kasabach-Merritt phenomenon and was resected completely without any recurrence. To the best of our knowledge, this is the first reported case in the literature of a KHE arising from the salivary glands in an adult.

Veillonella atypica causing retropharyngeal abscess: A rare case presentation

Veillonella species are obligate anaerobes which are part of the human oral, gut and vaginal microbiota. The genus Veillonella consists of 16 characterized species. Very few infections due to Veillonella atypica have been reported till date. Here we present a case of retropharyngeal abscess due to this organism in a 55-year-old lady.

Clinical and Current Microbiological Profile with Changing Antibiotic Sensitivity in Malignant Otitis Externa

Malignant otitis externa (MOE) is a rare and fatal condition affecting temporal bone. It is also known as skull base osteomyelitis and is a rapidly progressive condition. This retrospective study evaluates the clinical, haematological, microbiological profile and management of malignant otitis externa in a tertiary care hospital and literature review. A retrospective review of 79 patients diagnosed with Malignant Otitis Externa from January 2015 to June 2021 was analyzed. History and Clinical findings, Imaging, Bacteriology, Random blood sugar on admission, Erythrocyte Sedimentation rate, HbA1C level, Biopsy of the granulation tissue from Externa auditory canal, cranial nerve involvement, duration of hospital stay, and treatment outcomes were analyzed. Out of 79 patients, otorrhea, otalgia, EAC oedema, and granulation were the most common findings. Facial nerve paralysis was found in 20 patients (25.3%) and multiple cranial nerve paralysis in 5 patients (6.3%). Uncontrolled diabetes mellitus and older age have increased duration of hospital stay, while cranial nerve paralysis did not affect this duration. Six different microorganisms were isolated. Pseudomonas aeruginosa was the most common organism cultured. Ciprofloxacin resistance was detected in 79% of cases. Amikacin, Cefaperazone-Sulbactam, and Piperacillin were the most sensitive antibiotics for gram negative organisms in our study. This study reviews the current microbiological profile and shows the need for higher-end antibiotics to treat MOE in present times. Early diagnosis, aggressive control of diabetes mellitus, and long duration culture-sensitive antibiotic therapy with regular monitoring are essential to reducing morbidity and mortality due to MOE.

Recurrent Giant Mucoepidermoid Carcinoma of the Parotid: A Case Report and Review of Literature

Mucoepidermoid carcinoma is the most common salivary gland malignancy and about one third occurs in the parotid gland. The peak incidence is commonly seen between the third and fifth decades of life. It routinely presents as a fixed, painless mass below the ear. However, its presentation as a giant mass is exceedingly rare. Here, we report a case of a recurrent giant exophytic mucoepidermoid carcinoma in a young male. He underwent Revision Total Parotidectomy with Modified Radical neck dissection with Sural nerve grafting and an Anterolateral thigh flap reconstruction followed by Adjuvant radiotherapy. The rarity of the clinical presentation and the management challenges faced in a young male are being discussed in this case report.

Oesophagoscopy in a Treated Oral Cavity Carcinoma Patient: A Case Report and Review

Vegetable matter, especially fruit seed impaction, is uncommon in Otolaryngology practice. If it happens, there should be a possibility of abnormality in the oesophagus like stricture, web, malignancy, trauma or diverticulum. Here we present a case of seed as a foreign body oesophagus in a patient who was a known case of carcinoma left buccal mucosa status post left hemimandibulectomy with flap reconstruction Radiotherapy 20 years ago. We explained the practical and logistic issues while intubation and doing oesophagoscopy in this patient.

Intact Parathyroid Hormone Levels in Predicting Postoperative Hypocalcaemia After Total Thyroidectomy in South Indian Population: Cross Sectional Study

Hypocalcaemia being one of the most common complications after total thyroidectomy may not be avoidable in all cases. This study evaluated the effectiveness of intact Parathyroid hormone (iPTH) measured at 1-h after total thyroidectomy in predicting postoperative hypocalcaemia in early postoperative period in South Indian population. Patients who underwent total thyroidectomy in our institute from 2016 to 2018 were included. Preoperative calcium and iPTH levels were measured. Patients' iPTH level was measured 1 h after surgery and serum calcium level was measured at 24 h after surgery. Patients were also monitored clinically for any symptoms and signs of hypocalcaemia. A total of 57 patients were studied. The malignant causes accounted for 75.4% with papillary carcinoma thyroid being the most common cause. 65.7% of patients who underwent total thyroidectomy and 100% of patients who underwent total thyroidectomy with neck dissection developed hypocalcaemia. 70% of patients with low iPTH developed hypocalcaemia and none of the patients who had normal iPTH developed hypocalcaemia. This relation was statistically significant with p value of 0.018 (< 0.05). The positive predictive value is 70% and negative predictive value is 100%. Though our study supports the hypothesis that iPTH is effective in predicting hypocalcaemia after total thyroidectomy in the early postoperative period, a larger sample study is needed to further support this. It can be used to consider patients for early discharge or to prophylactically start oral calcium and Vitamin D supplementation based on iPTH levels at 1 h after surgery.

Migrated Foreign Body of Upper Digestive Tract-A Ten-Year Institutional Experience

The ingested foreign body is one of the commonest emergencies encountered by otolaryngologists Depending on the shape and duration of impaction, a small number of foreign bodies (1-2%) can perforate the wall of the gastrointestinal Tract. A migrated foreign body may remain quiescent or cause life-threatening suppurative and vascular complications. Data were collected retrospectively from the hospital records in a tertiary care hospital in South India from 2010 to 2020. Fifteen patients diagnosed with migrated foreign body and who underwent neck exploration were included in the study. Demographic details, mode of presentation, clinical and radiological findings, rigid esophagoscopy findings, neck exploration techniques employed were noted. The mean age of the patients was 37.66 years. All patients had a history of dysphagia, odynophagia, and point tenderness. All the patients underwent a lateral neck radiograph, and it was positive in 12 patients (80%), while in 3 patients (20%), it was negative. All the patients had a positive finding in Contrast-Enhanced Computed Tomography. Esophagoscopy was done prior to neck exploration to identify the site of injury and the probable site of migration. All the patients underwent lateral neck exploration, and foreign body was removed. Migrated foreign body can cause significant morbidity and mortality if not diagnosed and managed early. Strong suspicion and a systematic approach are needed for the diagnosis and management.

An Unusual Tumor in an Uncommon Site-Orbital Rosai-Dorfman Disease: A Case Report

Rosai-Dorfman disease (RDD) is also known as Sinus Histiocytosis with Massive Lymphadenopathy. It is a rare, benign, self-limiting disease of phagocytic histiocytes presenting with massive painless cervical lymphadenopathy. RDD can present as a nodal disease and also extra-nodal involvement with episodes of exacerbation and remissions and relapses after treatment. Its etiology remains poorly understood and is highly variable in its clinical presentation and response to treatment. Its treatment is poorly defined but the prognosis is usually fair. Here we are reporting a rare, unusual clinical presentation of infraorbital soft tissue mass diagnosed as RDD with cyto-histopathological correlation. Only a few such cases have been reported in the literature.

Microdebrider Assisted Resection of Suprastomal Lesions via Tracheostoma: A Novel Technique

Subglottic lesions are the commonest airway conditions leading to life threatening complications. Many conditions can present as subglottic lesions and can affect various age groups. There are various methods to manage these conditions described in the literature. We have devised a new method of managing these lesions by using a microdebrider inserted through the tracheal stoma. Here we describe three cases of subglottic lesions with pre-existing tracheostomy managed by this technique. The advantages and the post operative follow up of these patients are described. The follow up of the patients after 1 year showed significant improvement leading to their decannulation. Thus we would like to publish our results with scope of further research of this technique in this area and the treatment of such conditions affecting upper airway.

How Can We Manage Penetrating Neck Injury with Blunt Carotid Injury and Spinal Injury: Case Report and Review of Literature

The Neck is a cylindrical structure containing vital neurovascular and visceral structures tightly packed in a relatively small volume. Mortality rate increases when there is an injury to vascular structures especially the carotid artery, surrounded by other vital neurovascular structures; injuring the neck leads to devastating morbidity when compared to other injuries. With increased awareness of screening techniques and improved detection rates, there is an urge in opting for selective neck exploration and initial aggressive antithrombotic therapy for blunt carotid artery injuries. Here we report a case of a 20-year-old male, with a lacerated injury of the right side of the neck causing transection of the right internal jugular vein, grade 4 (Denver classification) blunt carotid injury, along with cervical vertebral fractures without neurological deficits. The patient underwent emergency surgical neck wound exploration, flush ligation of transacted Right Internal Jugular Vein, and conservative management for blunt carotid artery injury using anti platelets (Aspirin and Clopidogrel) avoiding any immediate neurological deficits. Whenever lacerated neck wounds are evaluated, the chance of blunt injury to the carotid is to be borne in mind and such an injury can be managed with double antiplatelet therapy, if there are no demonstrable neurological deficits.

Plasma Cell Granuloma of the Maxillary Sinus-A Case Report and Review

Plasma cell granuloma is a rare, benign, space occupying lesions occurring after recurrent infections. It most commonly involves young adults with lungs being the most common site. They are usually rounded masses with bony expansion and destruction without any life threatening complications and surgery being the best choice of treatment. Here we reported a 33 year-old female with plasma cell granuloma of the maxillary sinus treated with surgery and no recurrence has been noted.

'Shifting from anxiety to the new normal': A qualitative exploration on personal protective equipment use by otorhinolaryngology health-care professionals during COVID-19 pandemic

BACKGROUND

The novel coronavirus pandemic has influenced the working practice of health-care professionals who come across symptomatic and asymptomatic COVID patients in their day-to-day practice. Especially, among HCWs in otorhinolaryngology, with the risk of exposure being high, hence were mandated to use personal protective equipment (PPE).

MATERIALS AND METHODS

The change in perceptions and patterns of PPE use throughout the COVID-19 pandemic was studied in detail through interviews conducted among 15 key informants, and the data were analyzed using health belief model in our study.

RESULTS

A health belief model explains the trajectory of PPE use by otorhinolaryngology health care providers during the COVID-19 pandemic. The course of usage of PPE by otorhinolaryngology health-care professionals during the COVID-19 pandemic was explained through the health belief model. During the initial days of the COVID-19 pandemic, intense perceived severity and susceptibility to COVID infection led to PPE use, and otorhinolaryngology HCWs resorted to higher grade PPEs which gave optimal protection; but in course of time with a better understanding of the natural course of illness, minimal PPEs without compromising HCW safety were used with minimal discomfort. Perceived severity of COVID infection on self and family, health knowledge, influence of peers, and support from the institution encouraged them in using PPEs.

CONCLUSION

We found that various aspects of health belief model such as the perceived susceptibility, perceived severity of the disease, perceived barriers and benefits in PPE use, self-efficacy, health-related knowledge, and the cues to action influence PPE use among otorhinolaryngology HCWs. The key findings can be applied in behavior change models to promote the use of PPE in the hospitals, especially during the time of pandemic.

Naso-Bronchial Rhinosporidiosis

Rhinosporidiosis is a chronic mucocutaneous granulomatous disease caused by Rhinosporidium seeberi, commonly affecting the nose and nasopharynx. Endobronchial involvement is of rare occurrence but can pose challenging problems for diagnosis, surgical excision and anaesthetic management. We report a 40-year-old man with a history of recurrent nasal rhinosporidiosis who presented with unilateral nasal obstruction, cough, shortness of breath and a radiological feature of left lung collapse. Eight years since the last surgery, he presented with a recurrent lesion in the nose with concurrent endobronchial involvement. The patient underwent excision of the nasal and the endobronchial lesion successfully under general anaesthesia without any complication and good symptomatic improvement. The clinical presentation and the management of endobronchial rhinosporidiosis are discussed here. The surgical difficulties faced during the procedure are highlighted.

Middle turbinate angiofibroma in an adolescent boy

Bleeding nasal mass in adolescent boys has customarily been attributed to Juvenile nasopharyngeal angiofibroma. However, little is known regarding the extranasopharyngeal origin of angiofibroma, as highlighted in this case report of a 15-year-old boy who presented with recurrent epistaxis and nasal obstruction. On constructing a working diagnosis of nasal haemangioma, the patient was taken up for endoscopic excision under general anaesthesia. Intraoperative endoscopic findings and histopathological examination revealed the diagnosis of middle turbinate angiofibroma, which is an extremely rare extranasopharyngeal angiofibroma. Consequently, this represents the third described case of a juvenile angiofibroma arising from the middle turbinate.

Analysis of the prescription pattern of psychotropics in an outpatient department of a general hospital psychiatry unit

BACKGROUND

World Health Organization has prescribed drug use indicators for evaluating rational prescribing. Very few studies have been conducted on rational prescriptions for psychotropic drugs; hence, this study was undertaken at a tertiary care center of North India.

METHODS

After obtaining approval of the Institutional Ethics Committee, all prescriptions deposited with the dispensary of the psychiatry department of the hospital between 01 October 2017 and 31 December 2017 were included in the study. The prescriptions were analyzed for drug use indicators, namely the average number of drugs per encounter, percentage of prescriptions with generic name, percentage of prescriptions from the essential drug list, percentage of prescriptions with antibiotics, and percentage of prescriptions with an injection. In addition, the prescriptions were analyzed for patterns of psychotropics prescribed.

RESULTS

A total of 3770 prescriptions were analyzed. On an average, 2.35 medicines were prescribed per prescription. Injectable comprised 2.39% of prescriptions and fixed drug combinations were 0.16% of the total. Of all prescriptions, 91.3% were by generic name, while 55.02% of prescriptions were from the essential drug list. Polypharmacy constituted 4.53% of prescriptions. Risperidone, escitalopram, sodium valproate, and clonazepam were the most commonly prescribed drugs.

CONCLUSION

While we fared well with respect to the percentage of prescriptions with injections and those with an antibiotic, we have not been able to achieve the prescribed standards in prescription with generic names, number of drugs per prescription, and prescriptions from the essential drug list. The study emphasizes that there is scope for improvement.

Change in dysphagia and laryngeal function after radical radiotherapy in laryngo pharyngeal malignancies - a prospective observational study

Background

Intensity modulated radiotherapy (IMRT) has the perceived advantage of function preservation by reduction of toxicities in the treatment of laryngo-pharyngeal malignancies. The aim of the study was to assess changes in dysphagia from baseline (i.e. prior to start of treatment) at three and six months post treatment in patients with laryngo-pharyngeal malignancies treated with radical radiotherapy ± chemotherapy. Functional assessment of other structures involved in swallowing was also studied.

Materials and methods

40 patients were sampled consecutively. 33 were available for final analysis. Dysphagia, laryngeal edema, xerostomia and voice of patients were assessed at baseline and at three and six months after treatment. Radiation was delivered with simultaneous integrated boost (SIB) using volumetric modulated radiation therapy (VMAT). Concurrent chemotherapy was three weekly cisplatin 100 mg/m².

Results

Proportion of patients with dysphagia rose significantly from 45.5% before the start of treatment to 57.6% at three months and 60.6% at six months post treatment (p = 0.019). 67% patients received chemotherapy and addition of chemotherapy had a significant correlation with dysphagia (p = 0.05, r = -0.336). Severity of dysphagia at three and six months correlated significantly with the mean dose received by the superior constrictors (p = 0.003, r = 0.508 and p = 0.024, r = 0.391) and oral cavity (p = 0.001, r = 0.558 and p = 0.003, r = 0.501). There was a significant worsening in laryngeal edema at three and six months post treatment (p < 0.01) when compared to the pre-treatment examination findings with 60.6% of patients having grade two edema at six months. Significant fall in the mean spoken fundamental frequency from baseline was seen at 6 months (p = 0.04), mean fall was 21.3 Hz (95% CI: 1.5-41 Hz) with significant increase in roughness of voice post treatment (p = 0.01).

Conclusion

There was progressive worsening in dysphagia, laryngeal edema and voice in laryngo-pharyngeal malignancies post radical radiotherapy ± chemotherapy.

Comparison of the Efficacy of Septoplasty with Nonsurgical Management in Improving Nasal Obstruction in Patients with Deviated Nasal Septum – A Randomized Clinical Trial

Introduction In the current era, the major indication for septoplasty is nasal obstruction due to deviated nasal septum (DNS). Even though septoplasty is a commonly performed surgery, its effectiveness in relieving nasal obstruction in DNS has not been proven.

Objective The present study involved the measurement of both objective (nasal patency) and subjective (quality of life measures) outcome measures for the evaluation of the efficacy of septoplasty as compared with medical management.

Methods Patients with DNS presenting with nasal obstruction were included and randomized into a septoplasty group or into a nonsurgical management group, with 70 patients in each group. The improvement in nasal obstruction was assessed subjectively by the visual analogue scale (VAS), and the sino-nasal outcome test-22 (SNOT-22) and the nasal obstruction symptom evaluation (NOSE) questionnaires and was measured objectively by assessment of nasal patency by peak nasal inspiratory flow (PNIF) at 0, 1, 3, and 6 months of treatment in both groups.

Results The average VAS, SNOT-22 and NOSE scores for the septoplasty versus the nonsurgical group before treatment were 6.28 versus 6.0, 19.5 versus 15, and 14 versus 12, respectively, and at 6 months post-treatment, the scores were 2.9 versus 5.26, 10 versus 12, and 8 versus 10 (p = 0.001), respectively. The average PNIF scores at 0 and 6 months were 60/50 l/min and 70/60 l/min, respectively, in the septoplasty group (p = 0.001); the scores at 0 and 6 months in the nonsurgical management group were 60/60 l/min and 70/70 l/min, respectively (p = 0.001).

Conclusion Surgical correction of DNS by septoplasty improves nasal obstruction better than nonsurgical management at 6 months postsurgery.

A Trip Down the Bronchus- A Tracheostomy Complication in COVID Pandemic

Foreign body of the trachea and the bronchus are critical emergencies which can lead to life threatening complications. But the advent of the 2019 novel corona virus disease, pandemic has dramatically changed the comfort of these procedures since aerosol generating medical procedures pose a risk and spread of infection to the health care workers. Even the patients are uncomfortable visiting the hospital due to the fear of acquiring the COVID infection.A 41-year-old obese female with grade 4 subglottic stenosis status post tracheostomy presented with foreign body Fuller’s tracheostomy tube flange in the right bronchus during the COVID 19 pandemic. The patient had delayed presentation to the hospital due to fear of getting exposed to COVID and poor access to health care facilities due to lockdown imposed in various places in the nation. The patient was tested for COVID and taken up for surgery where rigid bronchoscopy and foreign body removal was done via the tracheostoma. The details of the procedure, challenges faced during the procedure, the effect of the COVID pandemic on the patients and hospital staffs are discussed. The complications of the broken tracheostomy tube can be most efficiently dispelled by proper tube care by the attenders and frequent tube change.

Lacrimal sac rhinosporidiosis

Rhinosporidiosis is a chronic mucocutaneous granulomatous disease caused by Rhinosporidium seeberi, involving primarily the nose and nasopharynx. Very rarely, the disease can affect the lacrimal sac. Here we report a 35-year-old male patient who had rhinosporidial involvement of the nose 5 years ago, for which he underwent endoscopic nasal surgery. Five years after the excision of the nasal mass, he presented with lacrimal sac involvement. The clinical presentation and the management of lacrimal sac rhinosporidiosis are discussed here.

Monte Carlo-based dosimetric studies of a locally developed170Tm LDR brachytherapy seed source

¹⁷⁰Tm is being explored as a source for applications in brachytherapy. Although it has adequate physical properties, such as a short half-life (128.6 d), high specific activity and a mean photon energy of about 66 keV, it has a drawback of low photon yield (only about six photon emissions/100 beta emissions). The objective of this work is to study the dosimetric characteristics of a locally developed¹⁷⁰Tm brachytherapy seed source using the Monte Carlo-based EGSnrc code system. In this study, we calculate the dose rate constant, air-kerma strength, radial dose function, anisotropic function and 2D dose-rate distributions in water. Separate simulations are carried out by considering the photon (gamma and characteristic x-ray) and beta spectra of the source. For regions close to the source (surface of the source <r< 0.4 cm), the dose is solely due to direct dose deposition by beta particles. At larger distances (0.4 cm <r<10 cm), the dose is due to bremsstrahlung photons produced by beta particles and photon emissions. The calculated value of the dose rate constant is 1.217 ± 0.052 cGy h^-1U^-1. The value ofS_kper mCi is 0.029 ± 0.0009 U mCi^-1. The contributions of the inherent photon emission and the bremsstrahlung photons to the totalS_kare 0.58 and 0.42, respectively.

Surgical corridors for congenital aural atresia with otogenic cerebellar abscess and lateral sinus thrombosis

The following is a case report of an adolescent with mental retardation who had congenital aural atresia with contralateral congenital facial palsy. She developed multiple intracranial complications (cerebellar abscess and lateral sinus thrombosis) due to cholesteatoma. We managed her in a multidisciplinary approach. This report discusses case management, emphasising the meticulous intraoperative steps taken in identifying the landmarks and precautions adopted to avoid postoperative facial palsy and other complications.

Comparison of efficacy of potassium titanyl phosphate laser & diode laser in the management of inferior turbinate hypertrophy: A randomized controlled trial

Background & objectives:

Inferior turbinate hypertrophy (ITH) is a common condition causing nasal obstruction. This study was undertaken to compare the efficacy of potassium titanyl phosphate (KTP) laser and diode laser in the reduction of the turbinate size.

Methods:

This randomized controlled trial included 209 patients with ITH. Pre-operative symptoms were assessed based on the Nasal Obstruction Symptom Evaluation (NOSE) score. Diagnostic nasal endoscopy was done to rule out other nasal sinuses. Nasal mucociliary clearance was measured by saccharin transit time (STT). Postoperatively, the NOSE score, STT and complications were assessed at days one and two, at one week, one month and three months.

Results:

Of the 209 patients analyzed at day one, the median NOSE score was 50 in the diode group and 40 in the KTP group, and at three months, 15 in the diode group and five in the KTP group. KTP laser showed a 93 per cent improvement in the NOSE score as compared to 77 per cent improvement shown by diode laser group. Among the intra-operative complications, of the 104 patients in the diode group, 6.73 per cent had burning sensation and 91.43 per cent had bleeding, and of 105 patients in the KTP group, 54.29 per cent had burning sensation and 36.54 per cent had bleeding. Among the post-operative complications in the KTP group, 32 and 34 per cent had bloody nasal discharge on days one and two, compared to 12 and 14 per cent in diode group. Crusting was present in 61 and 49 per cent on days one and two in KTP group as compared to 9 and 15 per cent in diode group, respectively. In the KTP group 30 per cent had synechiae as compared to 10 per cent in diode group.

Interpretation & conclusions:

KTP laser was more efficacious than diode laser in improving the NOSE scores but with slightly increased rate of complications in early post-operative period. Both the lasers impaired the mucociliary clearance mechanism of the nose till three months of post-operative follow up.

Quantification of biomaterial dispersion during otologic procedures and role of barrier drapes in Covid 2019 era - a laboratory model

BACKGROUND

Aerosol generation during temporal bone surgery caries the risk of viral transmission. Steps to mitigate this problem are of particular importance during the coronavirus disease 2019 pandemic.

OBJECTIVE

To quantify the effect of barrier draping on particulate material dispersion during temporal bone surgery.

METHODS

The study involved a cadaveric model in a simulated operating theatre environment. Particle density and particle count for particles sized 1-10 μ were measured in a simulated operating theatre environment while drilling on a cadaveric temporal bone. The effect of barrier draping to decrease dispersion was recorded and analysed.

RESULTS

Barrier draping decreased counts of particles smaller than 5 μ by a factor of 80 in the operating theatre environment. Both particle density and particle count showed a statistically significant reduction with barrier draping (p = 0.027).

CONCLUSION

Simple barrier drapes were effective in decreasing particle density and particle count in the operating theatre model and can prevent infection in operating theatre personnel.

Diagnostic delay for head and neck cancer in South India: A Mixed-methods Study

Background:

Early diagnosis is an important aspect of quality of cancer care.Analysis of the diagnostic delays and the reasons for delay helps to plan strategies to improve cancer care.

Objectives:

To determine the primary, secondary, and total diagnostic delay of patients diagnosed with head and neck cancer and to explore the reasons for the delay from the patient perspective.

Methods:

Explanatory mixed method design was used. Two hundred persons with a confirmed diagnosis of head and neck cancer attending the ENT (ear, nose, throat) cancer clinic in a teaching hospital before the initiation of treatment were included in the study. The median delay and the association of the delay with the various factors were analyzed. Sixteen one-to-one interviews of patients were done to identify the reasons for the delays from the patient perspective.

Results:

Median primary, secondary, and total diagnostic delays were 30 days, 30 days, and 73 days, respectively. Statistically, primary delay was found significantly longer among ever users of smokeless tobacco and significantly longer secondary delay was found among those with age less than 60 years. The reasons for the delay were grouped in the categories (i) Symptom appraisal delay due to low perceived seriousness and (ii) health-seeking behavior delay.

Conclusions:

The diagnostic delay was considerable. Measures to enhance symptom appraisal by improving health literacy, opportunistic screening, and strengthening the referral system would decrease diagnostic delay.

Periorbital Inner Canthal Arteriovenous Malformations: Percutaneous Glue Embolization in Three Cases

Inner canthal or palpebral arteriovenous malformations (AVMs) are uncommon and difficult lesions to treat if they are of high-flow type. Though they may present with mainly cosmetic reasons, they derive feeders from the ophthalmic artery and are associated with dangerous anastomoses. Percutaneous liquid embolic agent has been used to treat various head and neck vascular malformations and tumors and, if done in meticulous attention to detail, can offer cure or control before surgical excision. We report three adults who presented with medial canthal swelling and on imaging diagnosed to have high-flow AVMs. They underwent percutaneous n-butyl cyanoacrylate (glue) embolization and subsequently operated to excise the embolized malformation without any blood loss or complications.

MEASUREMENT OF OPERATIONAL QUANTITIES Hp(0.07) AND Hp(3) FOR INDIGENOUSLY DEVELOPED 106Ru/106Rh SOURCE USING AN EXTRAPOLATION CHAMBER

In the present study, a prototype 106Ru/106Rh source was fabricated using high level liquid waste from reactor fuel, fixed in a stainless steel housing with a window and backing made of silver. The study involves measurement of the operational quantities Hp(0.07), Hp(3) and the percentage depth dose (PDD) using an extrapolation chamber. It also involves determination of necessary correction factors to arrive at Hp(0.07) and Hp(3) following International Organisation for Standardisation (ISO) and methods suggested in literature. The study facilitates incorporation of the 106Ru/106Rh source as a beta reference source for quality assurance programme in TLD personnel monitoring as per the guidelines of ISO.

Dosimetry of indigenously developed 177Lu patch source for surface brachytherapy-Experimental and Monte Carlo methods

This paper describes the evaluation of dosimetry characteristics of an in-house developed ¹⁷⁷Lu skin patch source for treatment of non-melanoma skin cancer. A ¹⁷⁷Lu skin patch source based on Nafion-115 membrane backbone containing 3.46 ± 0.01 mCi of activity was used. Activity measurement of the patch source was based on gamma ray spectrometry using a HPGe detector. The efficiencies of the HPGe detector were fitted using an orthogonal polynomial function. The absorbed dose rate to water at 5 μm depth in water was determined using an extrapolation chamber, EBT3 Gafchromic film and compared with Monte Carlo methods. The correction factors such as Bragg-Gray stopping power ratio of water-to-air and chamber wall material being different from water, needed to be applied on measurements for establishing the dose rate at 5 μm depth, were calculated using the Monte Carlo method. Absorbed dose rate at 5 μm depth in water (surface dose rate) measured using an extrapolation chamber and EBT3 Gafchromic film were 9.9 ± 0.7 and 8.2 ± 0.1 Gy h^-1 mCi^-1 respectively for the source activity of 3.46 ± 0.01 mCi. The surface dose rate calculated using the Monte Carlo method was 8.7 ± 0.2 Gy h^-1 mCi^-1, which agrees reasonably well with measurement. The measured dose rate per mCi offers scope for ascertaining treatment time required to deliver the dose for propitious therapeutic outcome. Additionally, on-axis depth dose and lateral dose profiles at 5 μm and 1 mm depth in water phantom were also calculated using the Monte Carlo method.

Effect of Incudostapedial Reconstruction Using Conchal Cartilage Interposition Graft on Hearing Outcome

Introduction  Chronic otitis media is a widely prevalent condition in developing countries and is a cause of correctable hearing loss. The most frequent ossicular chain defect found during surgery for chronic otitis media has been a discontinuity of the incudostapedial joint. This study observes the effect of incudostapedial reconstruction using conchal cartilage on the hearing of the patient.

Objectives  To evaluate improvement in hearing by incudostapedial reconstruction using conchal cartilage interposition graft in tympanoplasty and to identify the independent factors associated with erosion of the long process of incus among patients with chronic suppurative otitis media tubotympanic type.

Methods  This study was conducted in the department of ear, nose and throat (ENT) amongst 22 patients with tubotympanic-type chronic suppurative otitis media who were found to have erosion of the long process during tympanoplasty. These patients underwent incudostapedial reconstruction using conchal cartilage. Their hearing was again reassessed at 12 weeks postsurgery, and the changes were observed.

Results  A statistically significant improvement in air conduction by 15.14 dB was found after undergoing incudostapedial reconstruction using conchal cartilage ( p  < 0.001). There was no statistically significant change in bone conduction ( p value > 0.05). A total of 59.1% of patients in the study had an improvement in hearing ranging from 11 to 20 dB. It was also found that 50% of the patients had a postoperative hearing of 10 to 20 dB.

Conclusion  Conchal cartilage interposition graft effectively improved hearing when used for the reconstruction of the incudostapedial joint during tympanoplasty in patients of chronic suppurative otitis media.

Hearing loss in tympanic membrane perforations: an analytic study

<p class="abstract"><strong>Background:</strong> Tympanic membrane perforations are common cause of hearing loss. There are very few systematic studies that have evaluated the size and location of a perforation to the degree of hearing loss, this study correlates the size and location of tympanic membrane perforation to the pattern of hearing loss.</p><p class="abstract"><strong>Methods:</strong> The study design was based on cross sectional study. Ninety-six ears of dry tympanic membrane perforation of CSOM mucosal type were selected. Photographs of the tympanic membrane perforations were taken and size measured using the “Image J” software. The area of perforation was compared to hearing loss measured by pure tone audiometry.  </p><p class="abstract"><strong>Results:</strong> Ninety-six patients, aged 15-60 years with perforated eardrums were studied. Size of tympanic membrane perforation showed moderate level of correlation with hearing loss (Pearson r value=0.463). The various locations of perforations were: posterior (23 ears with Mean hearing loss 28.6±7.7 dB), anterior (31 ears with Mean hearing loss 26.5±7.8dB), subtotal (42 ears with Mean hearing loss 34.2±8.2 dB).</p><p class="abstract"><strong>Conclusions:</strong> The hearing loss is frequency dependent, with maximum hearing loss at lower frequencies. Irrespective of size of perforation the hearing loss was the least for frequency of 2000Hz. Magnitude of hearing loss increases with increase in size of tympanic membrane perforation. Perforation posterior to handle of malleus resulted in more hearing loss than perforations involving anterior to the handle of malleus.</p>

Safety and Efficacy of Autologous Platelet-rich Fibrin on Graft Uptake in Myringoplasty: A Randomized Controlled Trial

Introduction  Chronic suppurative otitis media is a common ailment in developing countries, and it generally presents with otorrhea and hearing loss. Different surgical procedures have been used to treat otitis media; among them is myringoplasty, which is a procedure that includes repair of the tympanic membrane. Platelet concentrates have been used widely in different types of wounds and are found to improve wound healing. Hence, the use of platelet-rich fibrin in myringoplasty will also improve the tympanic membrane healing. Objectives  To assess the safety and efficacy of autologous platelet-rich fibrin on graft uptake in myringoplasty. Methods  Eighty-six patients were observed during the study period of two years. Forty-three patients in the study group underwent myringoplasty aided with platelet-rich fibrin, and 43 patients in the control group went through the same procedure but without the platelet-rich fibrin. The patients were observed for three months postoperatively by a blinded observer. Results  A total of 4.7% of the patients in the study group had postoperative infection, compared with a rate of 19% in the control group ( p  = 0.039). The graft uptake success rate was found to be 97.7% in the study group as compared with 81% in control group ( p  = 0.012). The results were found to be statistically significant. Conclusion  Being autologous in nature, and by comparing the groups, platelet-rich fibrin is safe for patients. The postoperative graft uptake rate is better in cases in which platelet-rich fibrin was used. The postoperative infection rate was also lower in the same group.

Dynamic Slow Motion Video Endoscopy as an Adjunct to Impedance Audiometry in the Assessment of Eustachian Tube Function

Introduction  Eustachian tube (ET) dysfunction plays an important role not only in the pathophysiology of various middle ear disorders, but also in predicting the outcome of the treatment. As there is no single test that assesses both the anatomic and physiological functions of the ET, a combination of tympanometry and dynamic slow motion video endoscopy may improve the sensitivity of ET function assessment.

Objective  To find out if there is any correlation between dynamic slow motion nasal video endoscopy and impedance audiometry in assessing ET function in patients with middle ear diseases.

Methods  Ours was a descriptive study performed with 106 patients attending the Ear, Nose and Throat (ENT) Outpatient Department of a tertiary care center in South India with features suggestive of middle ear disease. All patients underwent impedance audiometry and dynamic slow motion nasal video endoscopy, and were graded based on the severity of the ET pathology.

Results  A total of 47 out of 97 patients with abnormal endoscopy findings also had abnormal impedance audiometry. The correlation was greater among the patients with higher grades of ET dysfunction. The endoscopy findings of 106 cases, when correlated with middle ear manometry, revealed that 56 cases showed complete agreement, and 50 cases showed disagreement. The nasal endoscopy results, when correlated with middle ear manometry studies by using McNemar's chi-squared (χ ² ) test, showed a significant association between the 2 tests ( p  = 0.017).

Conclusion  There is a significant alteration in middle ear pressure as the severity of the ET tube dysfunction increases. Impedance audiometry and nasal endoscopy provide a better measure of ET function.

Assessing the Viability of Hadad Flap by Postoperative Contrast-Enhanced Magnetic Resonance Imaging

INTRODUCTION

The Expanded Endonasal Approaches (EEAs) have been widely used for various skull base lesions. The reconstruction of the skull base defects is of vital importance to prevent postoperative complications. The vascular pedicled-nasoseptal flap (Hadad-Bassagasteguy flap) is used as a workhorse in reconstruction of majority of the defects.

AIM

The purpose of this study was: (a) To assess the postoperative MRI appearance of vascularised pedicled nasoseptal flap for its viability; (b) To determine the variations in MRI that may suggest potential flap failure.

MATERIALS AND METHODS

A prospective study of 13 patients was done, who underwent endoscopic skull base surgery with reconstruction using the Hadad-Bassagasteguy flap. Pre-operative MRI was done to assess the size, extent and location of the lesion and a postoperative MRI was done to evaluate flap configuration, enhancement patterns, location, flap thickness and signal intensity characteristics.

RESULTS

The postoperative MRI of all patients showed a detectable flap covering over the skull base defects forming an "open cup" appearance. They were uniformly isointense on T1-weighted/ fat suppressed images to the adjacent nasal mucosa and hyperintense on T2-weighted images. On the MRI scans done after four weeks, all 13 of our patients had enhancing flaps. One flap migrated slightly to the left side; however, there was no Cerebrospinal Fluid (CSF) leak.

CONCLUSION

Vascular pedicle nasoseptal (Hadad) flaps are being widely used. MRI is a very useful tool in assessing the viability of the flap postoperatively and to evaluate for variations that may suggest potential flap failure.

Factors predicting early diagnosis of pediatric laryngotracheobronchial foreign bodies

OBJECTIVE

To study the clinical and radiological findings to make early diagnosis of foreign body (FB) aspiration in children.

METHODS

This prospective study was conducted on 45 children below 12 years of age with a clinical diagnosis of FB aspiration undergone rigid bronchoscopy from September 2008 to may 2010.

RESULTS

Bronchoscopy was positive for FB in 37 children. The results of these 37 children (15 female and 22 male) were analyzed. 81% of children were in age group of 1-3 years. Penetration syndrome (sudden onset coughing, choking and gagging when the child is having something in the mouth) (89.2%) and decreased breath sounds (86.5%) were the most common clinical features. Cough, respiratory difficulty and fever were present in 83.8%, 78.4% and 27% respectively. Tachypnoea, tachycardia, chest retractions, decreased chest movements and wheeze were present in 83.3%, 83.3%, 83.3%, 51.4% and 43.2% respectively. Unilateral hyperinflation (64.9%), mediastinal shift (45.9%), and collapse (21.6%) were common radiological sign on chest radiograph and in 13.5% patients the chest X-rays were normal. Sites of FB lodgments were larynx, trachea, right main bronchus, left main bronchus and bilateral bronchi in 10.8%, 10.8%, 35.1%, 37.8 and 5.5% respectively. Food related FBs were present in 30 cases (peanut in 54.1%) and inorganic FBs were present in 7 cases. FBs were removed successfully by rigid bronchoscopy in all cases without any mortality.

CONCLUSIONS

Penetration syndrome, localized decreased breath sounds, unilateral hyperinflation and/or mediastinal shift on radiology are predictors for early diagnosis of FB aspiration.

Voice Outcome Following Carbon Dioxide Laser Assisted Microlaryngeal Surgery

Very few studies have been conducted in South Indian population to evaluate glottic function and voice outcome following carbon dioxide (CO2) laser assisted microsurgery for benign lesions of the larynx. This is a descriptive study which aims at assessing the voice outcome (perceptual and acoustic) and vocal fold function (stroboscopic) following CO2 laser excision in benign vocal fold lesions. 50 adult patients with benign laryngeal lesions were selected to undergo CO2 laser excision in super-pulse mode at power setting of 6 watts. Perceptual analysis was done using GRBAS score. Voice analysis was done using Praat software and fundamental frequency, jitter, shimmer and harmonics to noise ratio were assessed. Stroboscopy was done to evaluate vocal fold function using glottic closure and mucosal wave pattern as parameters. Evaluation of these parameters was done pre-operatively and at 2, 6 weeks and 3 months post-operatively. Perceptual analysis revealed a significant improvement in the GRBAS score after surgery (p < 0.001). Acoustic analysis showed that all the parameters improved significantly after surgery (p < 0.001). Stroboscopy showed that vocal fold function improved in 98 % of patients in terms of completeness of glottic closure and regular, periodic mucosal wave. Super-pulse micro-spot carbon dioxide laser is a safe and effective treatment option for benign lesions of vocal folds, with excellent voice outcome.

The Clinical Utility of Vestibular Evoked Myogenic Potentials in Patients of Benign Paroxysmal Positional Vertigo

CONTEXT

Vestibular Evoked Myogenic Potentials (VEMP) is an emerging tool to diagnose Benign Paroxysmal Positional Vertigo (BPPV). The clinical utility of VEMP has been reported only in small accord in Indian literature.

AIM

To study the latency and amplitude of VEMP in patients with BPPV and compare it with that of normal subjects.

SETTINGS AND DESIGN

The study included two groups. Group one (control group) were 18 normal subjects. Group two (test group) were 15 subjects with unilateral BPPV.

MATERIALS AND METHODS

Those subjects who fulfilled the selection criteria based on case history and audiological assessment were taken for the VEMP recording. The VEMP response consist of positive and negative successive waves (pI-nI), with latency values in adults about 13 and 23 milliseconds respectively.

STATISTICAL ANALYSIS

Data was analysed using Statistical Package for Social Sciences (SPSS) version 12 (Chicago, IL, USA). Unpaired t-test was employed to measure the statistical difference between control group and test group.

RESULTS

The difference in n23 and the peak to peak amplitude between the ipsilateral and contralateral ears of the test group were statistically significant, whereas such a difference in the p13 latency turned out to be statistically insignificant. It should be noted that, out of 15 patients in the test group, five patients showed only artifact tracer recordings in both the ears which is considered as no response. The heterogeneity of the results extended from absence of VEMP to prolongation of both p13, n23; prolongation of p13 alone; and even side to side variations.

CONCLUSION

Absent response from the ipsilateral ear, prolonged latency of n23 and decreased peak to peak amplitude (p13, n23), indicates the disease pathology. However, large sample size is required to draw further conclusions and to consolidate the usage of VEMP in the diagnosis of BPPV.

Monte Carlo-based dose calculation for (32)P patch source for superficial brachytherapy applications

Skin cancer treatment involving ³²P source is an easy, less expensive method of treatment limited to small and superficial lesions of approximately 1 mm deep. Bhabha Atomic Research Centre (BARC) has indigenously developed ³²P nafion-based patch source (1 cm × 1 cm) for treating skin cancer. For this source, the values of dose per unit activity at different depths including dose profiles in water are calculated using the EGSnrc-based Monte Carlo code system. For an initial activity of 1 Bq distributed in 1 cm² surface area of the source, the calculated central axis depth dose values are 3.62 × 10^-10 GyBq^-1 and 8.41 × 10^-11 GyBq^-1at 0.0125 and 1 mm depths in water, respectively. Hence, the treatment time calculated for delivering therapeutic dose of 30 Gy at 1 mm depth along the central axis of the source involving 37 MBq activity is about 2.7 hrs.

Pediatric recurrent acute suppurative thyroiditis of third branchial arch origin--our experience in 17 cases

OBJECTIVE

To describe clinical presentations, management and treatment outcomes of 17 cases of congenital pyriform sinus fistula (PSF) of third branchial arch origin presenting as left recurrent acute suppurative thyroiditis with cervical abscess.

METHOD

Medical record of these 17 cases (5-males, 12-females) presented during 2009-2013 were reviewed.

RESULTS

Average age was 9.6 years (range 3-15 years). Fistulous opening in neck was present in 10 cases (58.8%). Average number of episode of infection from first presentation to definitive diagnosis was 3 (range 2-5). All patient had history of incision and drainage (ID) of abscess (average 2, range 1-3). All cases had barium swallow and CT scan. Sixteen cases had telescopic hypopharyngoscopy. Barium swallow and telescopic hypopharyngoscopy detected PSF in 88.23% (15/17) and 100% (16/16) cases respectively. Fourteen cases were treated by transcervical excision (TE) (fistulectomy with left hemithyroidectomy), two cases were treated by endoscopic chemical cauterization (ECC) of internal opening at pyriform sinus using silver nitrate and only ID of abscess was done in one case. Success rate of TE and ECC was 93% and 100% respectively. Recurrence in one case initially treated by TE was managed successfully by ECC.

CONCLUSION

Presence of congenital PFS should be suspected when left-sided intra-thyroidal abscess formation occurs as gland is resistant to infection. Strong clinical suspicion, barium swallow study, telescopic pharyngoscopy and CT scan are the key to diagnosis. Both TE and ECC has comparable success rate. ECC may prove a useful and equally effective method of treatment for congenital PFS in future.

Fractured and migrated tracheostomy tube in the tracheobronchial tree

OBJECTIVE

To study the clinical presentation and management of fractured tracheostomy tube (FTT) presenting as tracheobronchial foreign body (FB) in children.

METHODS

A retrospective chart review of children with a diagnosis of FTT, FB in tracheobronchial tree was carried out. Data regarding the patients' demographic details, diagnosis, clinical presentation and management were noted and analyzed.

RESULTS

Total 8 cases (males 3 and females 5, average age 8.8 years, range 1-15 years) wearing tracheostomy tube for an average period of 2 years (range 3 months-4 years) were found. Indications for tracheostomy were bilateral abductor palsy, subglottic stenosis and congenital subglottic hemangioma in 4 (50%), 3 (37.5%) and 1 (12.5%) cases, respectively. Classical triad of FB aspiration (coughing/choking, wheezing and reduced breath sounds) was present in 6 (75%) patients. Aspirated FTTs were Jackson's metallic inner tube, Romson's polyvinyl chloride plastic tube and Fuller's outer tube flange in 4 (50%), 3 (37.5%) and 1 (12.5%) respectively. The most common fracture site was at the junction between tube and neck plates {in 7 (87.5%) children}. Sites of lodgment of FTT were right bronchus, trachea and both trachea and left bronchus in 5 (62.5%), 2 (25%) and 1 (12.5%) cases, respectively. FTTs were retrieved by transtracheostomal rigid bronchoscopy and exploring the tracheostomal wound in 7 cases and 1 case, respectively.

CONCLUSION

Though FTT presenting as pediatric tracheobronchial FB is rare, it should be considered in differential diagnosis in a tracheostomised child with respiratory distress. When diagnosed, FTT removal is best done using a rigid bronchoscope through the tracheal stoma.

Brachytherapy of intra ocular tumors using 'BARC I-125 Ocu-Prosta seeds': an Indian experience

Aim:

To report our experience of brachytherapy using ‘BARC I-125 Ocu-Prosta seeds’ for the management of intraocular tumors with regard to tumor control, globe preservation visual outcome, and patient survival at Sankara Nethralaya, Chennai, India between September 2003 and May 2011.

Materials and Methods:

We reviewed records of 35 eyes of 35 patients who underwent ophthalmic brachytherapy between September 2003 and May 2011. Twenty-one cases had choroidal melanoma, nine had childhood retinoblastoma, two had adult-onset retinoblastoma, and there were one case each of vasoproliferative tumor, retinal angioma, and ciliary body melanoma. Brachytherapy was administered using a 15- or 20-mm gold plaque with or without a notch. Brachytherapy was the primary treatment modality in all tumors other than retinoblastoma, wherein brachytherapy was done post chemoreduction for residual tumor.

Results:

For choroidal melanomas, the mean radiation dose was 68.69 ± 15.07 (range, 47.72-94.2) Gy. The eye salvage rate was 13/20 (65%) and tumor control rate was 16/20 (80%) at an average follow-up of 24.43 ± 24.75 (range, 1.5-87.98) months. For retinoblastoma, the mean dose was 45.85 ± 3.90 (range, 39.51-50.92) Gy. The eye salvage rate and tumor control rate was 5/6 (83.3%) at an average follow-up of 38.36 ± 31.33 (range, 4.14-97.78) months. All eyes with retinoblastoma needed additional focal therapy for tumor control and eye salvage.

Conclusion:

The results of this retrospective study confirms that the use of ‘BARC I-125 Ocu-Prosta seeds’ in episcleral plaques to treat intraocular tumors offers a viable option for the management of intraocular cancers.
