There are similarities and differences between rhinitis and sinusitis. First, in terms of symptoms, both have nasal congestion, nose, runny nose and other performance, but rhinitis generally flow clear nose mainly. In the case of sinusitis, the flow of yellow pus nose is generally a bit more. The second, the scope of the lesion is not the same, rhinitis lesion is mainly confined to the nasal cavity, the main nasal turbinates and nasal septum mucosal surface, sinusitis lesion in addition to nasal cavity lesion, but also involved in various sinuses, such as maxillary sinus, sieve sinus, butterfly sinus, frontal sinus and so on. Third, the clinical treatment is different. Generally speaking, sinusitis, including rhinitis, can be routinely treated with antibiotics, and rhinitis generally does not require the application of antibiotics. Fourth, in general, sinusitis requires surgery if it is recurrent, generally do open sinus surgery, and when rhinitis requires surgery, most do external displacement of inferior turbinate fracture and partial ablation of inferior turbinate plasma.
