Abstract
Recently, negative pressure wound therapy (NPWT) has been reported to be effective for the treatment of cervical infections including retropharyngeal abscess. The 71-year-old woman with retropharyngeal abscess presented in this case showed improvement of infection through longterm NPWT. She continued to complain of swallowing difficulties after recovery. In this case, we performed the transcutaneous injection of botulinum toxin at the cricopharyngeus muscle for the patient who developed dysphagia after treatment for retropharyngeal abscess and observed improvement in swallowing.
