Abstract
Parapharyngeal space infections are uncommon but associated with significant morbidity and mortality. Early surgical drainage remains the mainstay of treatment; however, the optimal surgical approach continues to be debated. Management typically involves either an external (transcervical) approach or a transoral route. We present the case of a 43-year-old woman with a deep parapharyngeal abscess unresponsive to empirical antibiotic therapy who presented with dysphagia, fever, and left cervical swelling. Computed tomography (CT) confirmed the presence of the abscess. Ultrasound-guided intraoral drainage was performed, followed by intravenous antibiotic therapy. The patient had an uneventful recovery and was discharged on the sixth hospital day. Parapharyngeal abscess is the second most common deep neck space infection after peritonsillar abscess. Accurate diagnosis relies on clinical evaluation and radiologic imaging, with CT considered the gold standard for both initial diagnosis and ongoing monitoring.
