A Clinical Trial on the Treatment of Chronic Rhinosinusitis with Continuous Ultrasound

Abstract

Abstract.[Purpose] Chronic rhinosinusitis is a common and long-term disease for which no definitive treatment has been established. The purpose of this trial was to examine the effects of continuous ultrasound on the treatment of patients with chronic maxillary and frontal sinusitis.[Subjects] Thirty adults with chronic rhinosinusitis (24 men, 6 women; age range, 18-65 yrs; mean, 35

Efeitos agudos do ultrassom terapêutico de 1-MHz na desobstrução nasal de indivíduos com rinossinusite crônica

“…Our findings are similar to those of Naghdi et al 12 and Ansari et al 9,10 who showed that the frequency of the main symptoms in chronic rhinosinusitis (facial pain, nasal congestion and nasal block, rhinorrhea, olfaction disorders, and coughing) decreased significantly following 1 and 3 MHz LIUST. These studies showed that the thickness of the sinus mucosa decreased, the meatal ostia became more open, and paranasal sinus lesions regressed after the 15 th day of LIUST at 1.0 W.cm -2 (SATA) for 5 minutes over the maxillary and frontal sinuses.…”

“…These studies showed that the thickness of the sinus mucosa decreased, the meatal ostia became more open, and paranasal sinus lesions regressed after the 15 th day of LIUST at 1.0 W.cm -2 (SATA) for 5 minutes over the maxillary and frontal sinuses. 10,12 Studies by Barros et al 11 demonstrated that only two sessions of pulsed mode LIUST at 1.0 -1.5 W.cm -2 for 3 minutes were not enough to decrease nasal block in 13 subjects with rhinosinusitis -with or without antibiotics. However, this approach significantly reduced other symptoms such as headaches and facial pain in these subjects.…”

“…8 Other studies have proposed using low intensity ultrasound therapy (LIUST) applied on the nose (maxillary and frontal sinuses). [9][10][11][12][13] Ultrasound (1 to 3-MHz) is low power and low intensity mechanical energy which is produced by passing a high frequency electrical current through a piezoelectric material. [14][15][16] Sound waves propagate longitudinally in biological tissues; particles vibrate parallel to the direction of waves.…”

“…[17][18][19] A few studies have demonstrated that LIUST-induced accelerated skin tissue repair results from local modulation of cell mediators/signalers such as nitric oxide, histamine and other cytokines that are involved in inflammation in healing; it also increases the number of fibroblasts and collagen synthesis. [16][17][18][19] There are few published clinical studies on LIUST as treatment or adjuvant therapy for chronic rhinosinusitis; [9][10][11][12] it seems plausible that LIUST may reduce nasal block and congestion by its physical and chemical effects on tissues, 13,21,22 reestablishing interstitial mucosal permeability, reducing the viscosity of paranasal sinus secretions and helping eliminate nasal discharges. [13][14][15] Thus, the main purpose of this study was to evaluate the short-term effects of continuous 1 MHz LIUST on nasal block and the symptoms of subjects with chronic rhinosinusitis.…”

Multimodal Frequency Treatment for Facial Pain Caused by Chronic Rhinosinusitis: A Pilot Study

“…There are several studies that used 1-MHz frequencies to treat CRS symptoms, including pain [38][39][40][52][53][54][55], but only one was conducted in English with comparable data. We obtained raw data for this study; it had a total of 20 patients treated with a 1-MHz frequency (1 W/cm 2 and 0.5 W/cm 2 ) at a 10% duty cycle [40].…”
