RESUMEN
Background: The prognosis of squamous cell carcinoma involving the oral cavity depends on various factors. The most important predictor of relapse and hence poor prognosis is the positive surgical margin of resected tissue. Therefore, it should be considered a priority while performing surgical resection
Objective: To estimate the frequency of presence of tumor cells on margins of histopathological specimens of oral squamous cell carcinoma after safe margin resection and the reoccurrence rate
Period: Two years from January 2015 to December 2017. Setting and design: This quasi experimental study was carried out at the department of oral and maxillofacial surgery, Mayo hospital, Lahore. Methodology: Fifty patients with squamous cell carcinoma of orofacial region requiring safe margin surgical resection were selected. Presence of tumour cells on margins of histopathological specimens was determined. And monthly follow up was done for six months to check the recurrence
Results: Histopathological results of margins of total 50 patient showed that 70% patient had negative margin,26 %patients had close margin and 4% patients had involved margin. Out of these patients 12% had recurrence of the disease
Conclusion: Margins are an important predictor of disease control and its recurrence
RESUMEN
Introduction: There are twelve cranial nerves and seventh one is the Facial cranial nerve, which supplies the muscles of facial expression. It gives of five terminal branches, which form a plexus with in the parotid gland. These branches exhibit variations in their branching pattern. Detection of the main trunk of facial nerve and its branches is important in all surgeries of this area, to avoid any injury that may lead to the loss of function of this nerve. This study has elaborated the branching and communications among the terminal branches of facial nerve in parotid gland
Objectives: To study the anatomical variations in the terminal branching and communicating pattern of the seventh cranial nerve and to observe the division pattern of the facial nerve trunk in parotid area
Study Design: It was carried out at Department of Forensics and Department of Anatomy in King Edward Medical University Lahore
Period: The study commenced in March 2014 after approval of the synopsis by the Advance Studies and Research Board of KEMU and was successfully completed in December 2015
Methodology: Dissection of one hundred hemi-faces in the Departments of Forensic and Anatomy at King Edward Medical University Lahore. Adult cadavers of both sexes were included and with mutilated face were excluded. A Descriptive Cross-sectional type of study. Collected data was analyzed in SPSS 13. Simple frequency/percentages tables and charts were used to presents the outputs. Chi-Square, Student t-test and ANOVA were used
Results: Branching and Communicating Pattern according to occurrence were: Type I, 9%, Type II, 39%, Type III, 20%, Type IV, 25%, Type V, 6%, Type VI, 1%. 95% cases showed bifurcation
Conclusion: Most common branching pattern was Type II [39%], and least common was Type VI [1%]. Surgery of Zygomatic region must be done carefully due to complexity of branching in this area
