Background:
Numerous approaches to access the parapharyngeal space have been described, each with associated morbidities.
Surgical Technique:
We describe the use of vertical ramus osteotomy to increase exposure of the parapharyngeal space.
Results:
We have been using this approach over the past 5 years and have found it to be the preferred approach to the parapharyngeal space.
Conclusion:
This approach provides excellent exposure with low risk to the facial nerve while allowing for adequate tumor resection. It also avoids facial scarring and oral contamination of the cervical wound.
