[Clinical application of the reconstruction of prevertebral fascia in cervical vertebrae anterior approach].

OBJECTIVE

To evaluate the preventive effect of the reconstruction of prevertebral fascia on the complication of cervical vertebrae anterior approach.

METHODS

One hundred and seventy-six patients with cervical vertebrae anterior approach were divided into two groups by throwing coins, coins for the positive, patients entered the group A, coins for the negative, patients entered the group B. Eighty-seven cases of group B were treated with cervical vertebrae anterior decompression, bone grafting and internal fixation with plate and screws. In other 89 cases of group A, prevertebral fascia were covered on the surface of the plate and screws as experiment group. The patients were followed up after three weeks, three months and 12 months. The incidence of the dysphagia was as observation indicator and was statistically analyzed.

RESULTS

The followed-up period was 3 weeks, 3 months and 12 months after operation. The incidence of the dysphagia of group A was respectively 25.8%, 9.0%, 5.6%; the incidence of the dysphagia of group B was respectively 25.3%, 20.6%, 14.9%. The dysphagia in the experiment group was lower than that in contrast group, 3 months and 12 months after operation (3 months P = 0.030, 12 months P = 0.049 < 0.05).

CONCLUSION

The reconstruction of prevertebral fascia is an effective method to avoid the dysphagia of cervical vertebrae anterior approach.
