A Comparative Study of Surgical Outcomes in Children with Cochlear Implantation Using Posterior Tympanotomy & Modified Veria Technique.

Purpose: To compare the two common approaches of cochlear implantations i.e., mastoidectomy with posterior tympanotomy approach (MPTA) and modified veria technique and to know whether veria technique and its later modifications are as efficacious as the classic approach in terms of duration of procedure, gain in hearing and acquisition and incidence of complications if any. Methods: A prospective comparative study was undertaken at a tertiary care teaching institute. 30 children were selected and randomised into 2 groups who then underwent surgery from the same surgeon after proper evaluation but with 2 different approaches. Their outcomes were then observed and compared in terms of surgical technique and complications and hearing outcomes. Results: 30 children were operated with 15 in each group. In the study, patients under Group A (MPTA) had mean surgical duration of 139.67 ± 16.53 min while Group B (modified Veria) had of 84.67 ± 11.72 min, which was statistically significant (p < 0.05). 1 patient in Group A suffered House Brackman grade 4 facial nerve injury that recovered over 3 months and another had discolouration of the skin flap. No complications were observed in group B. During follow-up CAP and SIR scores were compared and were found to be statistically non-significant between the 2 groups (p value > 0.05), but the paired differences within each group showed statistical significance (P value- <0.001). Conclusion: Veria Technique (and its later modifications) for cochlear implantation is a simple, safe and easy procedure, which is as efficacious as MPTA with added benefits of consuming lesser surgical duration.

Lateral Skull Base Lesions: Our Experience of 15 Years.

To analyse and report various aspects of lateral skull base surgery by describing the incidence and demographic variables, diagnostic and management challenges, surgical choices along with complications and their management and the long term morbidity and survival outcomes in our experience of 15 years. Retrospective review of complete records of all cases operated for lateral skull base tumors at a tertiary care teaching institution in India between timespan of 15 years from 2003 to 2018 was undertaken. 53 cases were selected and analysed. Those having follow up of less than 6 months were excluded. Outcomes were assessed in terms of incidence of types of tumors, benign or malignant, age and sex variation of the patients, staging status at presentation, status of facial and other lower cranial nerves pre-operatively, surgical techniques with complications if any, recurrences and survival. Of 35 benign tumors, tympanojugular paragangliomas were most common. Average age for these was 53 years with 19 females and 14 males. All were non-functional. Tinnitus and hearing loss were most common presentations. Class B2 and C1 tumors were most commonly encountered and the ITF A approach was most commonly used. Hearing loss and Facial palsy were commonest complication post-operatively. There were 2 recurrences. 18 malignancies were observed. Most were stage IV at presentation. Otorrhea and otalgia were most common presenting symptoms followed by hearing loss. 5 year survival was 55%. Successful treatment of lateral skull base lesions requires a multimodality therapy with team approach. Surgical resection is the primary management choice with variable approaches. ICA status related to the tumor is the most important consideration. Malignancies require more aggressive treatment for obtaining clear margins along with pre/post-op chemoradiation. Good results with acceptable complications can be obtained even with advanced tumors.

Sublabial Approach Versus Modified Denker's Procedure: A Comparative Study of Pre-maxillary Tissue Clearance in Covid-Associated Mucormycosis.

To compare the efficacy of the sublabial and modified Denker's procedure in clearance of fungal disease from the anterior wall of maxilla and the pre-maxillary area i.e. the difficult areas of maxillary sinus. A prospective observational study was conducted over a period of 2 months (April 21-June 21) in the ENT department of Sawai Man Singh hospital, Jaipur. All the patients with clinical involvement of the premaxilla or the cheek abutting the anterior wall of maxilla were included in the study population. Cases matched in both groups were subjected to debridement either by the sublabial or the modified denker's approach. Outcomes were measured by assessing the daily CRP values, post-operative DNE every 3 days after pack removal, and imaging at the end of 1 month. Repeat biopsies were performed in patients that still had persistent symptoms after getting operated on. 16 of the 60 patients (26.6%) operated on by the endoscopic approach showed evidence of residual disease on follow-up whereas only 5 patients (9.6%) in the other category had a similar outcome. Most of the recidivism was seen in the anterior maxilla. Lower rates of complications were found following debridement by the sublabial approach. Since the sublabial approach is the most direct approach for the key areas of fungal involvement of maxillary sinus, it is recommended over the modified Denker's procedure for disease clearance from pre maxilla and the anterior wall of maxillary sinus. This view is also supported by the lower rates of complications encountered following the former.

Invasive Fungal Infections in Dengue Recovered Patients: A New Phenomenon in the Covid-19 Era.

Invasive fungal rhinosinusitis was seen to rise to epidemic levels after the 2nd wave of ongoing Covid pandemic, especially in tropical countries, maximally in India. A similar trend is being observed for cases who have recently recovered from dengue virus infection. Post dengue invasive fungal infection is a new presentation and any associations between it and Covid pandemic need to be studied in detail to help prepare for any complications. 3 patients presented to the out-patient department of E.N.T at a tertiary level teaching hospital in East India with complains similar to rhinosinusitis. These patients were then evaluated and diagnosed to be infected from Mucormycosis and Aspergillosis fungal sinusitis after which they were managed with surgical debridement and systemic antifungal therapy. All had a recent history of recovery from Dengue virus infection and a possible association could be suspected. 3 patients presented with complains of pain over upper jaw with orbital swelling and loss of vision developing over a period of 24 days. Two of them had ulceration of hard palate. They were then subjected to Contrast MRI along with CT scan of the Paranasal sinuses which depicted pansinus involvement with intracranial extension in two patients. These were then planned for diagnostic nasal endoscopies along with biopsies which turned out to be Invasive fungal sinusitis in the form of Aspergillosis and Mucormycosis. All the 3 patients had recent history of recovery from Dengue virus infection and did not have any other co-morbidities. Covid Associated Mucormycosis (CAM) is a well-known entity now but no reports of Dengue associated Invasive fungal sinusitis are yet reported. Whether this new phenomenon has anything to do with the interactions between dengue virus and coronavirus is not known at present and needs to be studied in detail so appropriate management protocols can be formulated.

Encapsulated Follicular Variant of Papillary Thyroid Carcinoma: A review on Surgical Treatment.

Differentiated thyroid carcinoma is one of the commonest malignancies in head and neck region. Among differentiated thyroid carcinoma, papillary carcinoma is the commonest. Encapsulated follicular variant of papillary thyroid carcinoma tumors are very indolent tumors which behave like benign tumors. Many tumors have been over diagnosed and over treated in spite of their indolent nature. We aimed to find out if total thyroidectomy is really required for very low grade tumors like encapsulated FVPTC. We operated 672 patients of thyroid disease during 2012 to 2020 in SMS Medical College, Jaipur. Out of 256 patients, 199 patients (78%) had papillary carcinoma of thyroid. Classical variant was present in 40% and follicular variant was present in 35% (N-69). Out of 69 patients with follicular variant of PTC, 59 patients had well encapsulated type of follicular variant of PTC while 10 patients had invasive type of follicular variant of PTC. Encapsulated FVPTC are less aggressive and indolent tumors. They should be treated more conservatively. Hemithyroidectomy is sufficient treatment for its complete cure. Out of 69 patients with Follicular variant of PTC, 59 patients had encapsulated disease. Out of 59 patients, 14 (24%) had bilateral nodular disease. 45 (77%) patients had unilateral disease; multicentric in one lobe in 9 (15%) patients and unicentric in 36 (61%) patients. However, encapsulated FVPTC was only found in predominant lobe and the non dominant lobe had benign disease.

Clinical Profile of Cognitive Decline in Patients with Parkinson's Disease, Progressive Supranuclear Palsy, and Multiple System Atrophy.

BACKGROUND: There are very less data on the comparison between the cognitive profile in Parkinson's disease (PD) and Parkinson's-plus groups, especially in India. AIMS: The aim of this study is to compare the cognitive profile across PD, progressive supranuclear palsy (PSP), and multiple system atrophy (MSA) groups and compare them using Mini-Mental State Examination (MMSE), frontal assessment battery (FAB), and verbal fluency tests. SETTINGS AND DESIGN: This was a cross-sectional study. MATERIALS AND METHODS: MMSE, FAB, and verbal fluency tests were administered in a total of 73 patients constituting 22 patients in MSA, 26 patients in PD, and 25 patients in PSP group, respectively. Twenty-six participants both age- and gender-matched were enrolled in control group. STATISTICAL ANALYSIS: Statistical analysis was done using SPSS Version 20.0. Descriptive statistics were done to find out the mean and standard deviation of different variables. ANOVA was done for followed by post hoc Bonferroni test to assess the cognitive function in three groups. RESULTS: ANOVA showed that there is a significant difference for MMSE scores (P = 0.038) being worse scores for PSP and maximum for MSA. A significant difference was found for FAB scores within three groups. There is a significant difference for FAB scores (P = 0.00003) being worse scores for PSP and highest scores obtained for PD. All the subtests of FAB test differed significantly except motor programming across MSA, PSP, and PD groups. CONCLUSIONS: Our data suggest that global cognitive impairment and executive dysfunction are worst in PSP among the three groups. Patients with MSA had significant cognitive decline as opposed to previous experience. FAB scores and verbal fluency tests are good tests to assess cognitive impairment in these diseases. Subsets of FAB score have significant differences but cannot help differentiating conclusively between these three diseases.

Clinical Profile of Dysphagia in Patients with Parkinson's Disease, Progressive Supranuclear Palsy and Multiple System Atrophy.

BACKGROUND: Swallowing changes are commonly observed in Parkinson's and Parkinsonism plus syndromes. Expeditious identification is necessary to provide early intervention in this population to avoid risk of aspiration and swallowing complications. OBJECTIVE: To investigate swallowing problems using detailed case history and swallowing speed on 3 ounce water test in three groups i.e. PD, MSA and PSP groups and further, to compare it with control group. SUBJECT AND METHODS: Cross sectional study design. A total of 73 patients were classified in MSA, PSP and PD for testing aged between 38 yrs and 70 yrs according to respective diagnostic criteria. A simple bedside water swallowing test was performed using 90 cc of water. Detailed assessment was done to check swallowing function. RESULTS: The mean age of both experimental group and control group was 62.4±8.37 yrs. and 61.05±7.07 yrs. Males were affected more in every pathological group compared to females. The dysphagia presented earlier in PSP and MSA groups as compared to PD groups. The water swallowing speed was found to be significantly less than 10ml/sec amongst three neurological groups compared to control group. The patients were found to have significant difficulty in parameters like repetitive swallowing, transferring food bolus through mouth, and food sticking in throat after swallowing. CONCLUSIONS: This is the first study comparing clinical profile of dysphagia in patients with PD, MSA, and PSP. Although there is no specific pattern of dysphagia for each of these disorders, the presence of some findings may provide clue to the diagnosis and necessary intervention.

Drug Abuse as an Emanating Risk for Stroke in Young Adults.

Drug abuse is a substantial risk factor for stroke among patients under 45 years of age and ranks second among the most commonly identified potential risk factors. Drug abusers aged 15 to 44 years are 6.5 times more likely to have a stroke than non drug users. Stroke occurring in persons under 45 years of age accounts for only 4% of all strokes but causes an enormous toll in personal suffering, lost productivity, and health care costs.

Morvan's syndrome with anti contactin associated protein like 2 - voltage gated potassium channel antibody presenting with syndrome of inappropriate antidiuretic hormone secretion.

Morvan's syndrome is a rare autoimmune disorder characterized by triad of peripheral nerve hyperexcitability, autonomic dysfunction, and central nervous system symptoms. Antibodies against contactin-associated protein-like 2 (CASPR2), a subtype of voltage-gated potassium channel (VGKC) complex, are found in a significant proportion of patients with Morvan's syndrome and are thought to play a key role in peripheral as well as central clinical manifestations. We report a patient of Morvan's syndrome with positive CASPR2-anti-VGKC antibody having syndrome of inappropriate antidiuretic hormone as a cause of persistent hyponatremia.

Chronic meningitis with multiple cranial neuropathies: A rare initial presentation of Wegener's granulomatosis.

Wegener's granulomatosis (WG) is a systemic necrotizing vasculitis that affects the small blood vessels. It mainly affects the upper and lower respiratory tract and kidneys. Central nervous system (CNS) involvement is rare, and has been reported only in about 8% of cases during the course of illness. Initial presentation with neurologic affection, particularly chronic hypertrophic meningitis is very unusual. We report the case of a 34 year old male who presented with chronic hypertrophic meningitis and multiple cranial nerve involvement as the initial manifestation, without respiratory and renal symptoms. This case highlights the difficulties in diagnosing a rare disease with rarer presentation, and at the same time illustrates that Wegener's granulomatosis should be considered in the differential diagnosis of chronic meningitis.

Immunohistochemistry, a valuable tool in detection of cervical lymph node micrometastases in head and neck squamous cell carcinoma: a prospective study.

The regional failure after comprehensive clearance of neck metastasis and consequent pathological report of N0 disease has been reported fairly frequently. The role of recurrence of disease in the neck in the cases has been variously reported by different authors. The light microscopy does not detect the micrometastasis and the specimen is reported negative for metastasis. The presence of micrometastasis (the reason for neck failure) has been reported by many studies as 5-58 % (mean 19.6 %). These figures are significantly high. The present study was done to ascertain the micrometastasis after comprehensive neck clearance (pN0 report). Two groups of patients were included in this study. (1) Group I included patients with N0 necks (80 patients). (2) Group II included Patients with N+ necks (107 patients). We found that 20 % case were reported N0 (Group I) in light microscopy but on immunohistochemistry these were positive for disease. 15 % upstaging was reported in N+ cases (Group 2). Immunohistochemistry has been more sensitive for cancer detection and has significantly changed the tumor staging and its consequent management.

A 3-year study of supraomohyoid neck dissection and modified radical neck dissection type I in oral cancer: with special reference to involvement of level IV node metastasis.

The present study was undertaken to determine the pattern and incidence of predictable lymphatic spread and skip metastasis in oral cancer and analyze the prognostic implications of different therapeutic modalities in the neck metastases. The study includes 81 patients with squamous cell carcinoma of oral cavity with T1-2N0M0 and T1-3N1-3M0 who were admitted to the Department of ENT and Head and Neck Surgery, SMS Medical College and Hospital, Jaipur, from June 2006 to May 2008. After complete diagnostic evaluation (imaging, FNAC), all these patients were operated (wide primary excision with SOHND/Extended SOHND/MRD-I) and followed up periodically till date. Occult metastasis was found in 26% of the patients. Level I, II, III was most commonly involved. We did not find any metastasis or recurrence at level IV in N0 cases. Involvement of level IV node in N0 and N+ neck were 0 and 9%, respectively. We did not find any "skip metastasis" at level IV in oral cancers. We concluded that SOHND for N0 and MRND type I for N+ neck for oral cancers is an appropriate treatment.
