Anterior surgery of the upper part of the cervical spine by prevascular extraoral approach.
Anterior surgery of the upper part of the cervical spine, that is, proximal to C3, may be performed by transoral approach, possibly enlarged by glossomandibulotomy, by a retrovascular extraoral approach, or by a prevascular extraoral approach. The authors describe the surgical method of prevascular extraoral approach that allowed them to effectively treat osteoma localized at C2 and C3, post-laminectomy instability at C3 and C4, solitary metastasis at C3. As compared to transoral surgery the prevascular extraoral approach has the advantage of avoiding the risk of infection from germs in the oral cavity and of allowing for easier postoperative management, avoiding tracheotomy and/or prolonged dysphagia. As compared to a retrovascular approach the prevascular approach obtains a truly anterior exposure instead of an anterolateral one. Prevascular extraoral approach should thus be used whenever possible. Transoral surgery is indicated for decompression, of the brainstem and a bilateral retrovascular approach may be used to perform anterolateral fusion at C1-C2.
