Maxillary sinus retention cysts are probably common findings on PNS series. Many patients remain asymptomatic in the presence of these lesions, but a variety of local and systemic symptoms have been associated with them. A patient presented with symptoms of chronic rhinosinusitis had a finding of both maxillary sinus retention cysts on PNS series. He has taken the Gal-gen-tang and treated by acupunture & infra-red. After about 4 months' treatment, his symptoms resolved and PNS series were normal. In conclusion, Maxillary sinus retention cysts may become clinically important when they occur in the setting of symptoms compatible with chronic rhinosinusitis, or when the diagnosis is in doubt.
