Abstract

Nasal obstruction is one of the most common complaints in pediatric otolaryngology. Generally nasal obstruction is caused by anatomic abnormalities of the nasal cavity, inflammation of the nasal mucosa, adenoid vegtation and hypertrophic tonsils in children. The severity of the symptom -varies from patient to patient. The size of the nasopharyngeal airway and adenoids on the posterior pharyngeal wall has been assessed by clinical inspection with the posterior rhinoscopy. However, this inspection may be difficult to carry out in children and has limited value in physiologic aspect
I can measeure the nasal obstruction objectively and reliably with rhinomanometry. 32 patients with nasal obstruction were evaluated preoperatively and postoperativeley. We compared the effects of the two types of surgery by measuring the total nasal resistance(TNR) of rhinomanometry (Rion SR11) during inspiration.
The results were as folloes ;
1) The group who undewent tonsillectomy, adenoidectomy and submucous diatermy had more significant improvement of symptoms than the group who underwent just tosillectomy and adenoidectomy(p < 0.05)
2) The preoperative TNR of all the patients during inspiration was o.360Pa/cm3/sec and 0.275Pa /cm´/sec in postoperative period(p<0.01). The group who underwent tonsillectomy and adenoidectomy had a preoperative, TNR of 0.377Pa/cm3/sec and postoperative TNR of 0.292Pa/cm3/ sec. The group who underwent tonsillectormy, adenoidectormy and submucous diathermy had a pre-operative TNR of 0.348Pa/cm3/sec. This changed into a postoperative TNR of 0.261Pa/cm3/sec (p< 0.01).
3) The difference of the TNR between preoperative group and postoperative group was statisti
tally significant (P< 0.01).
