Yellowish-smelling nasal mucus is often seen in chronic rhinitis, sinusitis or sinus cysts, as well as the bottom of the nose after the infection of the cysts of the clinical symptoms. If the symptoms of chronic rhinitis and sinusitis, first of all, we should use nose spraying drugs Coxsulam or Renoxolone, plus rhinitis drugs, Cang Er Zi Rhinitis Drops or Nasal Abyssal Oral Liquid, and at the same time, we can use pro-excremental drugs, Ginotropic or Mucosolvan. If the chronic sinusitis is not only accompanied by runny nose, but also headache and dizziness, then sinus CT can be used to make a clear diagnosis and then consider surgical treatment options. If it is only limited to the maxillary sinus, the maxillary sinus puncture treatment can be done alone.
