Evidence for the role of nasal endoscopy in the diagnosis of allergic rhinitis

Study	Year	LOE	Study design	Study groups	Clinical endpoint	Conclusion
Hamizan et al.786	2016	3b	Cross-sectional	Adults with rhinitis and nasal obstruction	Nasal endoscopy, allergy testing	MT edema is a useful nasal endoscopic feature to predict presence of inhalant allergy.
White et al.785	2014	3b	Cross-sectional	Adults with isolated MT polypoid edema	Nasal endoscopy, allergy testing	Isolated MT polypoid edema is associated with positive allergy testing.
Eren et al.783	2013	4	Case series	Adults with rhinitis	Nasal endoscopy, AR diagnosis	Nasal endoscopic findings do not provide reliable diagnosis of AR.
Ameli et al.782	2011	4	Case series	Children with suspected AR	Nasal endoscopy, AR diagnosis	Inferior or middle turbinate septal contact was predictive for AR, whereas pale turbinates were not.
Jareoncharsri et al.784	1999	4	Case series	Adults and children with PAR	Nasal endoscopy, nasal symptoms	No significant correlation between individual symptoms and endoscopic findings.

AR = allergic rhinitis; LOE = level of evidence; MT = middle turbinate; PAR = perennial allergic rhinitis.
