<s>[INST] Im 20-year-old female, height: 1.51 m, weight 44 kg. I have rhinitis and allergic skin. I have a problem with my jaw. my left jaw looks wider than the right one, such as swelling in the left jaw because of the mass. There is no pain when I touch them, they are a bit hard. doctor said that theyre maybe lipoma and have to confirm with FNA biopsy to make sure. actually, Im not sure theyre lipoma because they cant be felt to move slightly under skin when I press on them. is it true lipoma or other diseases? is it okay if I dont go for surgery? [/INST] Thanks for your query, I have gone through your query. The asymmetry of the face could because of swelling secondary to any defect in the mandible like hemimandibular hypertrophy or hypotrophy or condylar hypoplastic or hyperplasia. It can also because of the masseter muscle hypertrophy or intramasseteric lipoma. Consult an oral physician and get a radiograph like OPG to rule out any tooth or bone related pathologies and get an ultrasound to rule out lipoma. I hope my answer will help you. Take care. </s>
