Mitigating Infectious Complications of Injection Pharyngoplasty with Calcium Hydroxyapatite for Velopharyngeal Insufficiency: Retropharyngeal Abscess and Osteomyelitis.

Abstract

Velopharyngeal insufficiency is a complex condition with various treatment options. In this case, a patient with a cleft palate who was treated for velopharyngeal insufficiency with calcium hydroxyapatite injection pharyngoplasty developed persistent cervical pain on postoperative day 6. CT imaging showed a hypodense structure in the right retropharyngeal tissue, and cultures tested positive for Streptococcus intermedius and Staphylococcus aureus. An MRI later revealed skull base osteomyelitis. The infection was controlled via surgical intervention and antibiotics. This case highlights potential severe complications from injection pharyngoplasty and it underscores the importance of early recognition and management of infectious complications.
