[Therapeutic effect of vadian neurectomy under the nasal endoscope on the vasomotor rhinitis].

OBJECTIVE

To explore the therapeutic effect of vadian neurectomy under the nasal endoscope on the vasomotor rhinitis.

METHODS

Anatomic measurements of vadian canal in 14 cadavers were carried out, and vadian neurectomy under the nasal endoscope was performed on 51 patients with vasomotor rhinitis.

RESULTS

Anatomic measurements showed vadian canal was located behind the sphenoid-palatine hole, and its external orifice was shaped as infundibular. The vertical diameter was (3.5+/-0.9) mm and the horizontal diameter was (2.9+/-0.5) mm. The distance to the rotundum foramen and nasal septum was (6.1+/-1.2) mm and (10.5+/-5.9) mm. Longitudinal axes of the vadian canal was (27.0+/-9.6) degrees with the horizontal plane, and (7.8+/-2.5) degree with the sagittal plane. Among the 51 patients, 41(80.4%) patients showed complete response and 3(5.9%) partial response at the 5-year follow-up.

CONCLUSION

Vadian neurectomy under nasal endoscope is an effective technique for vasomotor rhinitis.
