Summary

The purpose of the study is to evaluate the therapeutic effect of erythromycin phonophoresis in reducing chronic rhinosinusitis.

Detailed description

Chronic rhinosinusitis (CRS) is defined as "inflammation of the nose and the paranasal sinuses characterized by two or more symptoms, one of which should be either nasal blockage, obstruction, congestion or nasal discharge (anterior or posterior nasal drip) with/without facial pain or pressure, reduction or loss of smell, endoscopic signs of nasal polyps, mucopurulent discharge primarily from middle meatus, oedema, mucosal obstruction primarily in middle meatus and computed tomography (CT) changes (mucosal changes within the osteomata complex and/or sinuses)". CRS may be a benign disorder, but it has significant morbidity. If not treated, the quality of life is poor. The condition is known to exacerbate asthma and can even lead to meningitis and brain abscess formation- which increases morbidity and mortality. Patients with chronic sinusitis who are treated usually have satisfactory outcomes. Symptom relief can be obtained after functional endoscopic sinus surgery in about 75% of patients who fail to respond to medical management. In rare cases, chronic sinusitis can result in orbital and intracranial infections, leading to visual and neurological deficits. This study will design to provide a guideline about effect of erythromycin phonophoresis on chronic rhinosinusitis and to assist in planning ideal treatment program. The treatment for chronic rhinosinusitis is realized through the use of medications such as corticosteroids, antibiotics and antimycotics or surgical procedures. However, treatments are not always effective, which makes patients adhere to other therapeutic modalities, including medicinal herbs, homeopathy and probiotics. A modality that stands out is the use of therapeutic ultrasound, which has shown promising results for its anti-inflammatory and antinociceptive activity.

Conditions

• Chronic Rhinosinusitis

Interventions

Type	Name	Description
OTHER	Erythromycin Phonophoresis	The procedures of ultrasound phonophoresis will be as follows: Patients will be positioned comfortably, sitting in a relaxed position. The physiotherapist will explain the treatment procedures to the patient. The device cables will be checked before each session. The treatment will last 5 minutes for each maxillary sinus. The frequency will be set to 1 MHz, and the intensity will be 1 W/Cm2 for the maxillary sinuses. The ultrasound will be pulsed, and the treatment will consist of 12 sessions, 3 days per week.
DEVICE	Ultrasound (US)	Therapeutic US is produced by a transducer composed of a piezoelectric crystal, which converts electric energy into alternating compression and rarefaction of sound waves at a frequency greater than 20 kHz. The amplitude of the US wave is proportional to the displacement of the US transducer head during each half cycle. The amplitude represents the wave energy. The ultrasound waves penetrate the tissue on the way to the target organ and have two mechanisms of action (thermal and non-thermal), which may potentially work synergistically to reduce nasal symptoms (nasal blockage and secretions).
DRUG	Topical Erythromycin	Erythromycin is a 14-member macrolide originally discovered in the 1950s. It has broad-spectrum antimicrobial action, inhibiting bacterial protein synthesis. studies have shown that erythromycin has immunomodulatory and anti-inflammatory activity independent of its antimicrobial action Erythromycin is a broad-spectrum macrolide antibiotic, wherein its bactericidal effect occurs by the inhibition of protein synthesis. It is used for the treatment of infections affecting the skin and mucosa; it shows immunomodulatory characteristics
OTHER	Medical treatment	Saline nasal wash 3 times daily for a month.
