What is a potential complication of a nasopalatine nerve block?

• A. Necrosis of soft tissue
• B. Hematoma
• C. Prolonged numbness
• D. Infection

Answer: (A)

When performing a nasopalatine nerve block, you’re aiming at the palatal tissue near the incisive foramen. A key risk here is tissue death from ischemia. The palatal mucosa has a delicate blood supply, and if a vasoconstrictor is used or injected in a way that markedly reduces blood flow to this area, prolonged ischemia can occur and cause soft tissue necrosis. This is the kind of complication tied directly to perfusion loss in the palatal tissues. While other issues like a hematoma or infection can happen with palatal injections, necrosis stands out as a potential consequence because it reflects a true loss of tissue viability from compromised blood flow.
