Objective: 
The aim was to describe a transoral endoscopic approach for large odontogenic jaw tumors and to assess the feasibility of endoscopy in complete enucleation of any tumor remnants.
Materials and methods: 
This retrospective cohort study was done on patients presenting with different types of large jaw tumors in the period from 2013 to 2017 at the Department of Otolaryngology – Head and Neck Surgery, Mansoura University, Egypt. All patients were managed endoscopically. with the bony port measured in its largest dimension. Outcome measures were the occurrence of recurrence during the follow up. Follow‑up ranged from 6 to 36 months.
Results: 
All patients had complete removal of tumor from the cavity with the transoral endoscopic approach through portal opening of the tumor cavity with a mean (SD) of 24.3 (3.12 mm).
Various types of odontogenic tumors were included. No recurrence was detected in the follow‑up period except for 1 case requiring a second look.
Conclusion: 
Management of large jaw tumors varies from incomplete excision as shaving to aggressive excision with greater morbidity requiring reconstruction. Endoscopic transoral route provides a marvelous option that ensures complete excision with functional preservation and less morbidity.
