In this study, we aimed to evaluate the efficacy of a diode laser for turbinate hypertrophy by using rhinomanometry. <strong>Methods:</strong> This cross-sectional study included 199 patients for 13 months. Preoperative, intraoperative, and 6-week postoperative rhinomanometry values were measured. <strong>Results:</strong> The most common intraoperative symptoms were olfactory annoyance (barbecue smell) (76.4%) and a painful burning or stinging sensation (64.3%). The inspiratory and expiratory mean nasal airflow values increased both intraoperatively and postoperatively, illustrating the effect of decongestants and inferior turbinate surgery. Intraoperatively, inspiration improved by 262.73 ± 196.09 (p < 0.01) and expiration by 247.94 ± 180.05 (p < 0.01). Postoperative inspiration improved by 254.03 ± 199.08 (p < 0.01) and expiration by 244.05 ± 194.57 (p < 0.01). Postoperative snoring (22.6%, p = 0.026) and nasal obstruction (20.2%, p = 0.042) were significantly higher in female than in male patients. <strong>Conclusions:</strong> The therapeutic efficacy of using diode lasers in inferior turbinate resection was established in this study on the basis of rhinomanometric data with a follow-up of 6 weeks. Postoperative nasal obstruction was effectively decreased and the other symptoms displayed a female preponderance.展开更多

The authors aim to provide objective measurements on their effects on the nasal airway. The aim is to study the feasibility of three novel intranasal stenting devices, AlaxoLito, AlaxoLito Plus, and AlaxoLito Xtreme, as treatment for nasal obstruction.CASE SUMMARY A 58-year-old man, who had right sided nasal obstruction, used stents during sporting activities intermittently for four years and subsequently in addition to intermittent sports use regularly for sleep for another two years. Magnetic resonance imaging(MRI) of the nasal passages and rhinomanometric measurements were taken with and without stents in situ. The stents tested are all braided from thin nitinol wires. The AlaxoLito Nasal Stent has a length of 35 mm.The AlaxoLito Plus and AlaxoLito Xtreme Nasal Stents have a length of 60 mm.Both have a diameter of about 10 mm in unloaded state and comprise a widened,ball-shaped section(which is positioned at the nasal alar) of about 11 and 14 mm,respectively. Rhinomanometric nasal airflow after application of the stents improved 1.11, 1.23, and 1.38 fold, respectively, with application of the AlaxoLito,AlaxoLito Plus and AlaxoLito Xtreme stents. MRI showed that after application of the stents, the nasal passage increased in diameter.CONCLUSION Intranasal stenting shows improvement in nasal airflow. Intermittent and regular longterm use had been shown to be safe, with no discomfort and no side effects.展开更多
