I recently invited as a faculty to do a master talk on rhinoplasty at Institute of Dental Sciences, SOA University, Bhubaneswar organized by Association of Oral and Maxillofacial Surgeons of India. The class mainly covered basic anatomy, various techniques, indications and implications of Rhinoplasty. This was mainly to motivate the budding maxillofacial surgeons.
And to break the stereotype that oral surgeons can only perform impactions, traumas and all. There are a lot more an oral and maxillofacial surgeons can perform. If you have the will to explore you can travel way long in your career.
