Changes in nasal airway resistance before and after intranasal contact point headaches / 临床耳鼻咽喉头颈外科杂志

ABSTRACT

OBJECTIVE@#To study the influence of endoscopic sinus surgery (ESS) on nasal airway resistance (NAR) of intranasal contact point headaches.@*METHOD@#The NAR and nasal airflow sensation were measured with anterior rhinomanometry in 20 patients (40 sides) before and after the ESS.@*RESULT@#A telephone follow-up six months after operation, 16 (85%) cases were cured, 3 (15%) were improved and 1 (5%) had no response and the effective rate was 95%. NAR decreased significantly after the operation. The change rates in NAR before and after the decongestion were (-0.34+/-0.23), (-0.75+/-0.21) and (-0.68+/-0.20), (-0.74+/-0.16) kPa x s/L, respectively, and there was a significant difference (P<0.05).@*CONCLUSION@#The improvement of nasal functions by ESS is due to the alteration of the anatomic structure of the nasal cavity and the amelioration of mucosal edema. The rhinomanometry can be used as a useful clinical tool in determining nasal patency.
