Effect of pulsed ultrasound on chronic rhinosinusitis: A case report

This case report demonstrates that pulsed ultrasound (US), when used for a total of 20 treatment sessions, provided symptom relief to a patient with chronic rhinosinusitis (CRS). A 16-year-old boy with a 12-month history of rhinosinusitis and candidate for sinus surgery was referred for ultrasound therapy. He presented with facial pain/pressure, nasal obstruction, and postnasal drip (total sinusitis score=7). On computed tomographic (CT) scanning, the total opacification of the right maxillary sinus was observed. The ostiomeatal complex was occluded (total CT score=6). Pulsed ultrasound was administered three times a week, every other day. After 10 treatment sessions, his symptoms were resolved with exception of nasal obstruction being mild (total sinusitis score=2). On CT scan, right maxillary sinus showed partial improvement (total CT score=2). After additional 10 treatments, the nasal obstruction was resolved, and follow-up CT scan of his sinuses showed that right maxillary sinus was clear and normal. At 6-month follow-up, the positive effects were maintained and the patient reported no recurrence of symptoms. Twenty sessions of pulsed ultrasound therapy eradicated the CRS and resolved the symptoms.
