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

ABSTRACT

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.
