From the abstract
Complete resection of the styloid process at its skull-base origin is challenging in recurrent Eagle syndrome because of postoperative fibrosis, distorted anatomy, and proximity to the internal carotid artery (ICA).
Reported results
Cadaveric dissections demonstrated a reproducible route to the styloid base through the parapharyngeal space using the medial pterygoid muscle, styloid musculature, and carotid sheath as key anatomical landmarks. Navigation guidance and Doppler localization of the ICA facilitated complete styloid base resection in the clinical case.
Authors' conclusions
Navigation-assisted pure endoscopic transoral styloidectomy provides a reproducible and minimally invasive approach for complete styloid base resection in recurrent Eagle syndrome.
