Why do i still have sinus problems if i had deviated septum surgery; ?

Not the only cause: A deviated septum is not always the cause of sinusitis. It may produce a nasal airway obstruction that contributes to sinusitis but there are many other possible explanations for the sinusitis. Testing the septum may relieve outflow o structuring but decongestants, drainage and antibiotics may still be needed.

Sinusitis?: The deviated septum may have had nothing to do with your sinus problems. You need to be reevaluated to determine your diagnosis.

Sinus surgery: Maybe you need sinus surgery. Have you nose evaluated by a board certified otolaryngologist.

See an ENT: for evaluation, imaging and treatment options.
