Thanks for the query. As per your chief complaints, there will be upper or lower jaw discrepancy or combination of both. Along with jaw discrepancy, teeth discrepancy can also be involved like cross bite
or scissor bite leading to improper occlusion. A complete clinical examination is required along with few x-ray investigation like lateral cephalogram for accessing the jaw discrepancy. After the diagnosis, treatment plan can be made out whether it can be treated with fixed appliance or with combination of orthodontic treatment and orthognathic surgery
.If there is jaw discrepancy, surgery is considered and planned based on various factors like age, growing or non growing patient, treatment outcome and prognosis.
So I would suggest you for clinical examination by your orthodontist along with x-ray investigation like lateral cephalogram which is having a minimal exposure compared to any other higher exposure scans.
Hope I have answered your query. Feel free to ask if you have any further query.
