Abstract: The authors have been monitoring influence of a therapeutic laser (LLLT), wavelength 830 nm, output 40 - 120 mW, on treatment of acute sinusitis in 194 patients in group I (consisting of 20 patients with diagnosis of sinusitis maxillaris unilat., bilateralis - 145, frontalis unilat. - 2, pansinusitis - 24 patients). Control group II consisted of 241 patients with the same diagnosis, treated without the use of a laser. Energy density applied on children was 1.6 J/cm2, 3 times every other day, on adults 2.5 J/cm2, 5 times every other day on every affected sinus. Laser probe was applied externally on the skin of frontal wall of the sinus. 30 patients were treated with laser only, 91 patients were treated with laser and antihistaminics, 73 patients were treated with laser, antihistaminics and antibiotics. A significant analgetic effect of laser irradiation was noticed in all groups, the number of punctures decreased substantially in comparison with group II, presumably thanks to release of outlets of the sinus and improved drainage, the time of treatment decreased significantly. No complications were noticed.

ABSTRACT: Chronic rhinosinusitis (CRS) is a common inflammatory disease of the nose and paranasal sinuses that has a significant impact on patients' quality of life. No study has examined the effectiveness of applying low-level laser therapy (LLLT) locally over the sinuses in patients with CRS. The aim of this study was to evaluate the effect of LLLT in patients with CRS. Fifteen adult patients with CRS participated in this pilot pretest-posttest clinical study. Patients were treated with a 830-nm Ga-Al-As laser in continuous-wave mode at a power output of 30 mW and energy dose of 1 J. Laser irradiation was delivered on six points over each maxillary or frontal sinus with 33 sec irradiation for each point and a total treatment duration of 198 sec for each sinus. Patients were given LLLT three times per week for ten treatment sessions. Patients were asked to score their symptoms in accordance with a four-point scale (0-3), and a total symptom score (TSS) for each patient was calculated. Percentage improvement of TSS was considered as the primary outcome measure. TSS was calculated at baseline (T0), at 2 weeks (T1) and at 4 weeks (T2). The TSS was improved significantly at T1 (39%) and at T2 (46.34%). A large effect size for LLLT was found (ηp2 ηp2  =  0.63). The therapeutic effect was sustained for a mean of 5 months. This pilot study indicates that LLLT applied for 4 weeks improves symptoms in patients with CRS.
