Depends on airway: You need an ENT evaluation including a fiberoptic scope of your airway. The key areas for concern are your nose, tongue base, tonsils, palate and uvula. If your anatomy is favorable surgery can help.

Snoring? Many Causes: One cause is nasal blockage due to deviated septum and enlarged turbinates, nasal allergies, or even nasal polyps (benign tissue growths inside the nose). Other woe could be in the palate, uvula, tongue, tonsils, a big jaw or lax throat muscles. You need to have a head and neck examination by an ent, a specialist expert in all areas of the nose and throat. You should be able to get help.

Oral Sleep appliance: Is my recommended choice, if that not resolve the issues you may consult with ENT and have surgery.
