INTRODUCTIONChronic nasal obstruction is very common and mostly caused by hypertrophied inferior turbinates.1 Inferior turbinates are the primary controllers of upper airway helping in adjusting of the volume of the inspired air and improving its quality by humidification, filtration and warming, thus protecting lower respiratory mucosa.
2Interruption of the normal nasal cycle results in persistent hypertrophy of the inferior turbinates which is aggravated by inhalant allergens, infection, airborne irritants.
3Impairment of nasal secretions drainage leading to recurrent respiratory infections with relative hypoxia and hypercapnia which leads to synthesis of inflammatory cytokines, and free nitrogen and oxygen radicals which may be responsible for impaired pulmonary functions. 4 Loss of nasal humidification and warming due to mouth breathing can lead to alterations in the diffusion and viscosity of the surfactant which may be a powerful stimulus for bronchiolar obstruction, consequently affecting daily activity and causes psychological disturbances. 5,6 To avoid this consequences, early medical management is mandatory, in the form of local corticosteroids, systemic corticosteroids, antihistaminics and anticholinergic.7 If medical treatment is insufficient or ineffective, surgical management (in the form of partial turbinectomy) should put in mind. 8 In this study we tried to correlate between the turbinectomy operation and its impact on pulmonary functions and daily activity. This was done objectively by using spirometry evaluating pulmonary functions and 6-minutes walking test evaluating the effect on the daily activity. The evaluation also was done subjectively by using VAS (visual analogue score) system by asking the patient about the improvement of nasal obstruction following the operation, and by using Lund and Kennedy scoring about ABSTRACT Background: Nasal obstruction due to persistent hypertrophy of inferior turbinates is very common affecting respiration and daily activity. Partial inferior turbinectomy is a very safe and effective operation overcoming the nasal obstruction and nasal resistance caused by hypertrophied turbinates. Methods: In this prospective descriptive study, we tried to evaluate the effect of the operation on pulmonary functions and daily activity objectively by using spirometry and 6-minutes walking test before and after the operation. Thirty patients were included in this study. Results: Significant improvement after the operation. Also, we use a subjective VAS score which revealed the same results, proving that, the pulmonary function tests improved significantly after partial inferior turbinectomy operation. Conclusions: Partial inferior turbinectomy is a very effective operation in the management of nasal obstruction caused by persistent hypertrophy of inferior turbinates resulting in improvement of the pulmonary function tests and daily activity after the operation without marked complications.
