چکیده
Introduction: Head and neck cancers form around 50% of all the cancers. 1 In India, it constitutes about 30% of all cancers. 2 It is the sixth most common cancer among all cancers in the world. 3 Squamous cell carcinoma is the most common malignant tumor found in the head and neck region.4 Lymphatic spread is considered as the most important mechanism of the spread of the head and neck cancers. 5 The rate of metastasis to cervical lymph nodes tells us about the aggressiveness of the primary tumor. The presence of cervical lymph. In this study we compared the diagnostic accuracy of clinical palpation and CT scan of the cervical lymph nodes with cytology for evaluation of lymph node metastasis.

Introduction:Most metastatic lymph nodes from head and neck malignancy are solid. Cystic nodes are found in 33% - 61% of carcinomas arise from Waldeyer’s ring, of which only 1.8% - 8% originate are from the nasopharynx. Some cystic cervical metastases were initially presumed to be branchial cleft cyst. This case report aims to highlight the unusual presentation of cystic cervical metastasis sec...

Introduction: Squamous Cell Carcinoma (SCC) is the most common head and neck malignancy. To decrease the side effects of treatment and mortality from disease relapse, careful staging for the proper treatment plan is necessary. The main purpose of this prospective study is to compare the diagnostic value of Computed Tomography (CT) and Magnetic Resonance Im-aging (MRI) in oral SCC and its lymph ...

I read the manuscript entitled “Case Report of An Open Neck Procedure Complication Associated with Laryngeal Mask Airway Use” by Subramaniam T et al. This is a valuable manuscript describing iatrogenic complications during level-2 cervical lymph node biopsy, in which the airway is managed with laryngeal mask airway (LMA). During the procedure, the surgeon realized that the mass was actually the...
