A Three-Step Submandibular Retropharyngeal Approach to the Craniovertebral Junction: Is Less Always More?
J Clin Med

Department of Neurosurgery, Fondazione Policlinico Universitario "A. Gemelli" IRCCS, 00168 Rome, Italy.
: Accessing the craniovertebral junction poses unique challenges due to its anatomical complexity and proximity to critical structures, such as the cord-brainstem junction, great vessels of the neck, cranial nerves, oropharynx, and rhinopharynx. Among the approaches that have been developed over the years, the submandibular retropharyngeal approach offers good antero-lateral access without the need of transgressing mucosal layers. In its traditional form, however, this approach involves multiple sequential steps and requires intricate dissection, extensive retraction, and meticulous maneuvering, which can increase operative time and produce approach-related morbidity.

Background: Chordoma is a rare malignant neoplasm that predominantly arises from the axial skeleton, but can also develop in unusual locations. However, there are also rare cases of "NOS" chordoma involving the oropharyx and epithelial-myoepithelial carcinoma of the parotid gland in the same patient. According to contemporary research, chordoma is a rare malignant neoplasm that arises from the embryonic remnants of the notochord.

Chordomas are slow-growing aggressive tumors that account for 1-4% of all bone tumors. The anatomical distribution of chordomas includes 50-60% in the sacrococcygeal region, 25-30% in the skull base and 15% in the mobile spine. Virchow was the first to describe and term these tumors as 'ecchordosis physaliphora' in 1857, and Muller established their notochordal origin in 1895.

Objective: The endoscopic endonasal approach (EEA) to the lower clivus and craniovertebral junction (CVJ) has been traditionally performed via resection of the nasopharyngeal soft tissues. Alternatively, an inferiorly based rhinopharyngeal (RP) flap (RPF) can be dissected to help reconstruct the postoperative defect and separate it from the oropharynx. To date, there is no evidence regarding the viability and potential clinical impact of the RPF.
