BackgroundThe goal of this study is to compare quality of life (Qol) and symptoms in 91 patients with a deviated nasal septum preoperatively and postoperatively with a control group of 93 healthy individuals.MethodsAll patients reported Qol on Sino-Nasal-Outcome-Test-20 (SNOT-20) and symptoms on visual analogue scale (VAS) preoperatively and 6 months after surgery and the results were compared with the controls.ResultsMean SNOT-20 score improved from 1.8(SD0.9) preoperatively to 0.9(SD0.8) postoperatively (p < 0.000) but did not reach the same level as the controls 0.4(SD0.5). Septum surgery leads to a significant symptom improvement for all symptoms investigated (p < 0.000) on VAS. The patients reached the same level as the healthy controls in 6 of 11 symptoms (headache, facial pain, sneezing, trouble with rhinosinusitis, cough and snoring) but the patients group had significantly more trouble with nasal blockage (VAS 29 vs 9), change in sense of smell (VAS 12 vs5), nasal discharge (VAS 22 vs 11), oral breathing (VAS 23 vs 13) and reduced general health (VAS 12 vs 5) also postoperatively (p < 0.01). Sub analyses showed that allergic patients reported a VAS score of 36 (SD30) for nasal blockage and 17 (SD22) for facial pressure postoperatively versus 23(SD22) and 6(SD13) in non-allergic patients (p < 0.03 and p < 0.01). Patients with obstructive sleep apnea syndrome (OSAS) reported more trouble with snoring on VAS postoperatively than other patients, 42(SD28) versus 20(SD23) (p < 0.002).ConclusionSeptoplasty leads to a highly significant improvement in Qol and symptoms. The patients do not reach the same level of Qol as healthy controls. All symptoms are reported as mild on VAS postoperatively.Allergic patients tend to report more nasal blockage and facial pressure postoperatively than other patients and a focus on medical treatment should be kept also postoperatively. Patients with obstructive sleep apnea report more trouble with snoring postoperatively and alterative treatment options for snoring may be considered in these patients.Electronic supplementary materialThe online version of this article (doi:10.1186/s12901-016-0031-7) contains supplementary material, which is available to authorized users.
BackgroundThe objective of this observational study was to evaluate the outcomes of intranasal surgery in patients with obstructive sleep apnea (OSA) in a single institution in Norway.MethodsFifty-nine patients with OSA and clinically significant nasal obstruction underwent either septoplasty alone or septoplasty with concomitant volume reduction of the turbinates from August 2008 until the end of December 2010. Subjects were scheduled for sleep polygraphy before and 3 months after treatment.In this observational single-centre cohort study we evaluated and compared the effect of these two specific surgical procedures on sleep related parameters.ResultsThere was a significant reduction in the apnea-hypopnea index (AHI) only in the group that had septoplasty with turbinate reduction (17.4, (SD 14.4) – 11.7, (SD 8.2), p <0.01), and this effect was significantly better than in the group treated with septoplasty alone. Other objective parameters remained unchanged. Subjective assessments obtained with a postoperative questionnaire showed an equally positive effect on diurnal sleepiness and nasal obstruction in both groups, and a better effect on sleep quality in the combined treatment group.ConclusionThe effect of nasal surgery on obstructive sleep apnea seemed to be greater when there were indications for combined surgery of the inferior turbinates and the nasal septum, compared to when there were indications for septoplasty alone.
OSA patients have a lower minimum cross-sectional area, nasal cavity volume and peak inspiratory flow compared to controls. Our study supports the view that changes in the nasal cavity may contribute to development of OSA.
ObjectiveTo evaluate the biomechanical properties of the soft palate and velopharynx in patients with obstructive sleep apnea (OSA) and nasal obstruction.Study designProspective experimental study.Materials and methodsTwo finite element (FE) models of the soft palate were created in six patients undergoing nasal surgery, one homogeneous model based on CT images, and one layered model based on soft tissue composition. The influence of anatomy on displacement caused by a gravitational load and closing pressure were evaluated in both models. The strains in the transverse and longitudinal direction were obtained for each patient.ResultsThe individual anatomy influences both its structural stiffness and its gravitational displacement. The soft palate width was the sole anatomical parameter correlated to the critical closing pressure, but the maximal displacement due to gravity may have a relationship to closing pressure of possibly an exponential order. The airway occlusion occurred mainly at the lateral attachments of the soft palate. The total transverse strain showed a strong correlation with maximal closing pressure. There was no relationship between the critical closing pressure and the preoperative AHI levels, or the change in AHI after surgery.ConclusionHyperelastic FE models both in the homogeneous and layered model represent a novel method of evaluating soft tissue biomechanics of the upper airway. The obstruction occurs mainly at the level of the lateral attachments to the pharyngeal wall, and the width of the soft palate is an indicator of the degree of critical closing pressure. A less negative closing pressure corresponds to small total transverse strain. The effect of nasal surgery on OSA is most likely not explained by change in soft palate biomechanics.Level of EvidenceNA.
