Tumor resection in the oral cavity results in mucosal defects leave the patient with noteworthy functional and esthetic defect & in OSF surgical management after releasing fibrotic bands defect created OSF surgical management in which after releasing fibrotic bands created a defect which needs to be reconstructed to avoid re-fibrosis. The flexibility of the nasolabial flap has been attributed to its reliable vascularity derived from numerous vessels within the vicinity. AIM: This study is designed to compare the island NLF with pedicled NLF used in patient having intraoral defects after small oncological resection and oral submucous fibrosis. METHOD: Study was conducted on patients undergoing treatment for intraoral lesions and oral submucous fibrosis requiring reconstruction using nasolabial flap on the patients reported to the department of Oral and Maxillofacial surgery in Rama dental college, Hospital and Research Centre, Kanpur. RESULTS: In our study we had seen the island NLF showed superior results as compared with pedicled NLF in few of our chosen criteria and overall, also. CONCLUSSION: Conclusions can be drawn from this study that both groups are more or less similar results with superiority towards island NLF
