Abstract
Objective: To determine the frequency of occult cervical metastasis in oral squamous cell carcinoma patients. Methods: This cross sectional study was conducted in the department of maxillofacial surgery, Mayo Hospital, Lahore from July 31st, 2015 to January 31st, 2016 on 100 patients of oral Squamous Cell Carcinoma (SCC) having clinically and radiologically negative nodes. Prophylactic functional neck dissection was done in each patient and was sent to the pathology lab for evaluation of any occult metastasis. Results: Overall frequency of occult cervical metastasis was found to be 27%. In 41(41 %) specimens of SCC of tongue, 13(31.7%) had occult metastasis. In Alveolar mucosa occult metastasis was found in 4(20 %) out of 20(20 %) patients. In SCC of buccal mucosa occult metastasis was found in 10(29.4%) out of 34(34 %) patients. In SCC of lip no occult metastasis was detected. Conclusion: Within the boundaries of the present study, it is concluded that occult cervical metastasis was most frequent in cases of SCC tongue, whereas no occult cervical metastasis detected in SCC of lip. Key Words: Squamous cell carcinoma, cervical lymph nodes, prophylactic neck dissection, occult cervical metastasis. Continuous...

Summary
Representation of oral cancers in men and women is 5% and 2%. Respectively.[1] Incidence of oral cancer varies with geographic distribution. An overall prevalence of 9% of oral cancers were found in Pakistan.[2] Among the oral cancer cases diagnosed globally, more than half of them are found in Asia where 168,850 new cases were diagnosed in this geographical region alone.[3] Out of all different types of oral cancers,90% were squamous cell carcinomas.[4] In Pakistan Oral squamous cell carcinoma is a major public health problem due to its poor survival rates and high morbidity.[5] The most common sites of the oral cavity involved by SCC are tongue and floor of the mouth. There is an increased incidence of occult cervical metastasis in lesions involving floor of the mouth and tongue, even in earlier stages of the disease.[2]
