<p class="abstract"><strong>Background:</strong> Oral cancer consists of a group of neoplasms affecting any region of the oral cavity. This term is commonly used interchangeably with oral squamous cell carcinoma (OSCC), representing the most frequent of all oral neoplasms. Factors affecting the development of the oral squamous cell carcinoma are tobacco use, alcohol consumption, low socio-economic status, poor hygiene, poor diet, viral infection like HPV, ill-fitting dentures, jagged teeth.</p><p class="abstract"><strong>Methods:</strong> An institution based retrospective observational study was conducted in the department of ENT, GMC Jammu, including the records of the patients with oral squamous cell carcinoma admitted from June 2016 to July 2019. 80 patients of oral carcinoma were included in the study.</p><p class="abstract"><strong>Results:</strong> Male to female ratio was 5.1:1. Mean age of presentation was 49.2±4.1 with most of the cases presenting in the 6^th decade. 27 (33.75%) patients had history of chewing tobacco alone, 17 (21%) had smoking with chewing tobacco and 10 (12.5 %) smoking with alcohol. 52% patients presented with growth of tongue (52%) followed by buccal mucosa (17.5%) and other sites. Histopathological grading of OSCC showed predominance of well differentiated cancer in 44 cases (55%).</p><p class="abstract"><strong>Conclusions:</strong> Cases of OSCC are increasing day by day in young generation due to increasing exposure to the risk habits which are easily accessible to them.</p>

<p class="abstract"><strong>Background:</strong> In India the overall incidence of cancer is low. However the cancers of head and neck have high incidence like that of larynx and pharynx.</p><p class="abstract"><strong>Methods:</strong> This is a retrospective study conducted in the department of ENT, SMGS Hospital, GMC Jammu, for a period of 3 years from June 2016 to March 2019. 112 patients with cancer of larynx and hypopharynx were included in the study.  </p><p class="abstract"><strong>Results:</strong> The male to female ratio in the present study was 9:1. Mean age of presentation of the patients was 57.9±4.6 years. Hoarseness was the overall the most common complaint of the patients presenting with malignancy of larynx and hypopharynx (80.35%), followed by the complaint of dysphagia (68.7%). Smoking and alcohol consumption was the most common risk factor associated. 78 (69.6%) had primary malignancy of larynx and 34 (30.4%) had primary malignancy arising from hypopharynx. Most common site of presentation for laryngeal cancer was supraglottis (56/78) while pyriform sinus was the most common site to be involved in hypopharynx (24/34). 76 out of 112 patients (67.8%) presented with neck nodes. 41% of the patients presented in stage III and 32.14% patients presented in stage IV malignancy.</p><p class="abstract"><strong>Conclusions:</strong> Malignant laryngeal and hypopharyngeal cancers are presented in late stages when management options become limited and survival of the patients fall significantly. Awareness of the symptoms developing due to laryngeal and hypopharyngeal cancer is necessary so that people can recognize the developing cancers in earliest stages.</p>

<p class="abstract"><strong>Background:</strong> For anterior mandibular defects, vascularized bone flap reconstructions are the best for providing a solid arch necessary to restore form and function, especially in patients receiving tumour excision surgery in head and neck region. Our aim was to study aesthetic and functional outcome of free fibula osteocutaneous flap (FFOCF) in anterior mandibular defects in case of anterior floor of the mouth malignancies with mandibular infiltration.</p><p class="abstract"><strong>Methods:</strong> The clinical data of 15 oral cavity carcinoma patients with involvement of anterior floor of mouth with mandiblular infiltration that underwent FFOCF reconstruction at our institute, government medical college, Jammu, was prospectively collected from January 2018 till January 2020. In this study, the aesthetic and functional outcome of these patients was evaluated at 6 months and 1 year post surgery.</p><p class="abstract"><strong>Results:</strong> The aesthetic result of reconstruction was excellent in most patients. Also, there was no long-term donor-site morbidity. There was no peri-operative death. Flaps survived in all patients. Functional outcomes including the ability to tolerate oral diet and speech outcome were good in all cases.</p><p class="abstract"><strong>Conclusions:</strong> The FFOCF, in reconstruction surgery of advanced oral cavity carcinoma permits more radical resection of tumour with good functional as well aesthetic outcome.</p>
