Table 1 Patients diagnosed with “posterior fossa lesion & CVJ malformation” and undergoing surgery reported in the literature [3,4,5]
Patient | Age (years) | Sex | CVJ malformation | Histopathology of the posterior fossa lesion | Occipitocervical fusion | Follow-up |
|---|---|---|---|---|---|---|
1 | 25 | M | BI, reducible AAD, C0-C1 and C2-3 fusion | Dermoid cyst | Occiput C2-C3 (using inverted U-shaped, contoured rod) | Good effect |
2 | 23 | M | BI, reducible AAD, C0-C1 fusion | Dermoid cyst | Occiput C2-C3 (using a contoured rod) | Good effect |
3 | 18 | F | BI, C2-3 fusion, irreducible AAD | Epidermoid cyst | Excision of the odontoid process via the transoral route + occipitocervical (occipital C2–C3) fusion | Good effect |
4 | 12 | F | Reducible AAD; C0-C1 fusion; C2-5 fusion | Dermoid cyst | Occipitoaxial fusion (using multiholed plates) | Good effect |
5 | 20 | M | Platybasia, BI, C0-C1 fusion, C2-3fusion | Dermoid cyst | Excision of the posterior fossa lesion by Poppen’s approach followed by transoral odontoidectomy and posterior fusion 2 months later. | Good effect |
