Summary
A dental patient developed chest pain and neck swelling after third molar extraction due to surgical emphysema. Using vented surgical handpieces can prevent this rare complication.
Area of Science:
- Oral and Maxillofacial Surgery
- Thoracic Medicine
- Medical Device Technology
Background:
- Third molar extraction is a common dental procedure.
- Complications, though rare, can arise from surgical techniques.
- Understanding potential iatrogenic injuries is crucial for patient safety.
Observation:
- A previously healthy woman experienced chest pain and cervical swelling post-third molar surgery.
- Chest X-ray revealed mediastinal and subcutaneous emphysema.
- Air was introduced via a high-speed turbine drill, not the air/water syringe.
Findings:
- The emphysema was caused by air dissection under the soft tissue flap during alveolar bone removal.
- The high-speed turbine drill, not the air/water syringe, was implicated in air introduction.
- Subcutaneous and mediastinal air resolved with oxygen administration.
Implications:
- Vented surgical handpieces are recommended to prevent air embolism and emphysema during dental extractions.
- This case highlights the importance of appropriate tool selection in preventing surgical complications.
- Prompt recognition and conservative management (oxygen) can lead to resolution of surgical emphysema.
