<p class="abstract"><strong>Background:</strong> Variations in sinonasal anatomy of adults<strong> </strong>are common and vary among different populations. Their role in development of pathological conditions such as sinusitis, epistaxis, etc is debated. Having clear picture of sinonasal anatomy of a person is essential in avoidance of complications during surgery. This study was done<strong> </strong>to<strong> </strong>analyze<strong> </strong>sinonasal anatomy in adults from Karaikal region having chronic sinusitis by nasal endoscopy and CT scan imaging.</p><p class="abstract"><strong>Methods:</strong> A total of 50 patients undergoing endoscopic sinus surgery were studied by preoperative nasal endoscopy, CT scanning and endoscopy at the time of definitive surgery and variations recorded and analyzed. </p><p class="abstract"><strong>Results:</strong> The incidence of the sinonasal anatomical variations in CT scan study were – discharge in the frontal sinus (100%), agger nasi cells (96%), deviated nasal septum (70%), anterior ethmoidal cells (86%), posterior ethmoidal cells (58%), sinus lateralis (52%), frontal cells (50%), discharge in sphenoid sinus (50%), pneumatised superior turbinate (46%), INSA (34%), prominent bulla ethmoidalis (30%), supra orbital cells (26%), pneumatised septum(16%), medialised uncinate process (16%), paradoxical middle turbinate (16%), Haller cells (14%), supreme turbinate (14%), pneumatised inferior turbinate (12%), frontal recess obliteration (12%), absent pneumatisation of frontal sinus (12%), pneumatised middle turbinate (10%), Onodi cells (6%), pneumatised uncinate process (2%), maxillary sinus septation (2%).</p><p><strong>Conclusions:</strong> The high incidence of variations emphasises the need for proper preoperative assessment for safe and effective endoscopic sinus surgery. </p>
<p class="abstract"><strong>Background:</strong> Hearing impairment is a common disability in children. This study is to evaluate the common high risk factors for hearing loss in our locality and to estimate hearing threshold by brain stem evoked response audiometry.</p><p class="abstract"><strong>Methods:</strong> 100 children under five years were subjected to brainstem evoked response audiometry. Wave V morphology was studied and hearing threshold estimated. The high risk factor(s) were analysed and degree of hearing impairment assessed. </p><p class="abstract"><strong>Results:</strong> 38 children were found to have hearing impairment. Most of the children had bilateral hearing impairment. Of them 30 children (79%) had profound hearing loss. Consanguineous marriage was the most common risk factor.</p><p class="abstract"><strong>Conclusions:</strong> Since consanguinity is the most common risk factor, health education and genetic counselling will help to decrease the incidence of autosomal recessive nonsyndromic deafness. Improvement in immunization for rubella can decrease the hearing impairment due to these infections. Due to availability of medical facilities hearing impairment due to perinatal factors have decreased.</p>
<p class="abstract"><strong>Background:</strong> <span lang="EN-IN">Malignant neoplasms of the nose and paranasal sinuses are rare and account for 3% of malignancies involving head and neck region. Maxillary sinus is the commonest area affected and squamous cell carcinoma is the commonest malignancy reported. Due to nonspecific clinical features, late presentations and poor accessibility tumours in these areas are both therapeutically and diagnostically challenging. Data about maxillary sinus tumours, especially from Karaikal are lacking. This prospective hospital-based study was conducted to determine the common benign and malignant tumours affecting the maxilla, their epidemiology and to analyse their clinical presentations.</span></p><p class="abstract"><strong>Methods:</strong> <span lang="EN-IN">Relevant epidemiological and clinical details were collected for all the patients with maxillary tumours and thorough clinical evaluation was performed. CT scan of head and neck region and histopathological examination of the lesion was carried out. All the details were tabulated and percentages were calculated for comparison and analysis. </span></p><p class="abstract"><strong>Results:</strong> <span lang="EN-IN">During two years period of the study 44 patients with tumours affecting the maxilla were detected, 32 (72%) being benign and 12 (27%) malignant. Incidence of both benign and malignant tumours was highest in the 51-60 years age group with male preponderance. Squamous cell carcinoma (58.33%) was the most common malignant histological variant found while inverted papilloma with squamous epithelium (62.5%) was the most common benign histological variant. In TNM staging, 42% patients had T4 and the remaining were T3 and T2. </span></p><p class="abstract"><strong>Conclusions:</strong> <span lang="EN-IN">In Karaikal region, inverted papilloma with squamous epithelial lining and squamous cell carcinoma are the commonest benign and malignant tumours of maxilla respectively. Although clinical manifestations of both benign and malignant lesions overlap, certain features like facial pain, cheek swelling, loosening of teeth which were found only in association with carcinoma should warrant thorough evaluation.</span></p>
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
