Objective: To establish demographics of OSCC patients presenting to a major tertiary care hospital and identify different potential risk factors. Study Design: Descriptive Cross Sectional study. Setting: Department of Oral and Maxillofacial Surgery Mayo Hospital Lahore. Period: July 2021 to July 2022. Material & Methods: A total of 86 patients were included in the study. The diagnosis of OSCC was histo-pathologically confirmed. Patients of both gender and all ages were included in the study and a standard questionnaire was developed to collect data including bio-data, demographics and history of illicit habits. Results: Out of 86 patients 75.58% (n=65) were males and 24.41% (n=21) patients were females. The mean age of the patients was 47.02 years. Male to female ratio was 3.6:1. Well differentiated squamous cell carcinoma was most common (53.48%), Majority presented with stage 4 disease. Highest proportion of the patients (29.6%) was having no obvious predisposing factor. Most commonly involved site was tongue followed by buccal mucosa. Conclusion: The disease trends are changing in our population, as the disease is increasingly affecting younger age group, tongue is now increasing being involved more commonly as in majority of the previous studies the incidence of OSCC of buccal mucosa was much higher, the incidence of OSCC without any obvious risk factor is increasing which needs further investigation.

Objective: To evaluate the accuracy of ultrasonography in diagnosis of infectious maxillofacial/swelling. Study Design: Simple Cross Sectional study. Setting: Outpatient Department of Oral and Maxillofacial Surgery Unit, Punjab Dental Hospital, Lahore. Period: February 2016 to August 2016. Material & Methods: Conducted on 100 patients. The patients were evaluated with the ultrasound diagnostic modality. The ultrasound interpretation of all the cases was done and best possible diagnosis was made and recorded regarding diagnosis of infectious maxillofacial swellings. The incisional biopsy of every patient was done for histopathology. All findings of ultrasound and histopathology were entered to a proforma. Results: The average age of the patients was 35.81±14.31 years. In this study, 63% patients were males and 37% were females. Out of 100 patients, 70(70%) patients had infectious swelling while 30(30%) did not have infectious swelling. The sensitivity of ultrasonography was calculated as 84.72%, specificity was 67.86%, positive predictive value was 87.14%, negative predictive value was 63.33% and diagnostic accuracy was noted as 80% taking histopathology as gold standard. Conclusion: It was concluded from results of this study that ultrasonography has enough diagnostic accuracy to diagnose infectious swellings of maxillofacial region.

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...
