%X Chronic sinusitis is one of the most common chronic diseases. In this research, intra- oral radiation of low-level laser has been compared with extra-oral low level laser radiation in treating maxillary chronic sinusitis for the first time. In this clinical trial, 40 patients were enrolled. Treatment plan was performed in 8 sessions, every other day, and using low-level diode laser with 810 nm. SNOT-22 questionnaire and rhinomanometry were used for evaluating patients. Mann whiteny, Fridman and wilcoxson tests were used for data analyses. P. value < 0.05 was considered statistically significant. All studied variables were improved using intra and extra oral low-level laser and this improvement was statistically significant (P. value<0.05). Comparing the two groups, Intra-oral laser therapy significantly (P. value<0.05) improved rhinomanometry variables compared to extra-oral laser therapy. The two groups showed no significant difference in improvement of clinical symptoms that contained in the SNOT-22 questionnaire except for sneeze which intra-oral laser therapy significantly decreased this variable (P. value<0.05). It should be noted that intra-oral radiation reduced all symptoms earlier than extra-oral radiation. After Six-months, in intra-oral group there was no significant difference between the results of completion and the results of 8th treatment session (P. value> 0.05). But in extra-oral group only post nasal discharge and thick nasal discharge were significantly increased compared with the results of the 8th session of radiation. Other symptoms showed no significant difference (P. value>0.05). Using intra and extra oral low-level laser therapy is a suitable way to treat patients with chronic maxillary sinusitis
