AbstractAs yet, there is no totally satisfactory means for treating hypertrophied turbinates and the proper management of turbinate dysfunction remains in question. In the present series, four of the widely practiced surgical procedures for the reduction of the size of the inferior turbinates were evaluated and compared. In all cases turbinectomy was performed as an isolated procedure. Eighty patients with chronic non-allergic rhinitis and hypertrophied inferior turbinates were selected, randomly divided into four groups, and followed up post-operatively for one year. Study of the results indicated that the beneficial effect of the operation is mainly mechanical by reduction of the resistance to nasal airflow. The post-operative improvement in smell acuity correlated positively with the increased patency of the nasal airway. None of the procedures had a deleterious effect on olfactory acuity. In contrast, the operation failed to enhance the mucociliary clearance rate or significantly decrease nasal drainage. Partial inferior turbinectomy and laser turbinectomy improved nasal breathing in 77 per cent of patients, and enhanced olfactory acuity in 78 per cent of patients who had pre-operative hyposmia. The results of turbinoplasty and cryoturbinectomy were less favourable. The surgical technique, advantages, and drawbacks of each of these procedures are discussed.

Objective: Spreader grafts are commonly used in rhinoplasty to achieve an aesthetic improvement of the nose or a functional improvement of the nasal airway. Currently, the aesthetic role of spreader grafts is well established. The functional effect of these grafts, however, has been controversial due to the lack of studies clearly demonstrating an increase on nasal airflow assigned to spreader grafts. The purpose of this study is to evaluate the effect of spreader grafts on nasal breathing. Methods: Nasal breathing of 72 consecutive patients undergoing rhinoplasty was evaluated by measuring peak nasal inspiratory flow (PNIF) before surgery and six months after surgery. Results: The mean preoperative PNIF of the 72 patients included in this study was 79.44 l/min and the mean postoperative PNIF was 110.42 l/min (p < 0.001). In 37 patients of this study no spreader grafts were used. In this group of patients the mean PNIF values changed from 73.24 l/min before surgery to 99.46 l/min after surgery. In the group of 35 patients in whom spreader grafts were used the mean PNIF values changed from 86.00 l/min before surgery to 122.00 l/min after surgery. The increase in the mean PNIF value after rhinoplasty was slightly higher in the group of patients with spreader grafts than in the group of patients without spreader grafts. The difference in the postoperative increase of PNIF between these two groups of patients, however, is not statistically significant. Conclusions: This study suggests that patients undergoing rhinoplasty have a statistically significant improvement in nasal breathing after surgery. However, patients receiving spreader grafts in a non-randomized way do not have statistically significant greater benefit than those who do not.

AbstractEvaluation of the nasal airway is crucial for every patient with symptoms of nasal obstruction as well as for every patient with other nasal symptoms. This assessment of the nasal airway comprises clinical examination together with imaging studies, with the correlation between findings of this evaluation and symptoms reported by the patient being based on the experience of the surgeon. Measuring nasal airway resistance or nasal airflow can provide additional data regarding the nasal airway, but the benefit of these objective measurements is limited due to their lack of correlation with patient-reported evaluation of nasal breathing. Computational fluid dynamics (CFD) has emerged as a valuable tool to assess the nasal airway, as it provides objective measurements that correlate with patient-reported evaluation of nasal breathing. CFD is able to evaluate nasal airflow and measure variables such as heat transfer or nasal wall shear stress, which seem to reflect the activity of the nasal trigeminal sensitive endings that provide sensation of nasal breathing. Furthermore, CFD has the unique capacity of making airway analysis of virtual surgery, predicting airflow changes after trial virtual modifications of the nasal airway. Thereby, CFD can assist the surgeon in deciding surgery and selecting the surgical techniques that better address the features of each specific nose. CFD has thus become a trend in nasal airflow assessment, providing reliable results that have been validated for analyzing airflow in the human nasal cavity. All these features make CFD analysis a mainstay in the armamentarium of the nasal surgeon. CFD analysis may become the gold standard for preoperative assessment of the nasal airway.

Our purpose was to assess the separate effects of nasal airflow and resistance on the activity of the nasal dilator [alae nasi (AN)] muscles. Nasal airflow and the AN electromyogram were recorded at rest and during progressive-intensity exercise at 60, 120, and 150–180 W in 10 healthy subjects who breathed nasally under all conditions. The activity of the AN muscles increased linearly as a function of the increase in nasal minute ventilation evoked by progressive-intensity exercise (r = 0.99, P < 0.002). Reciprocal changes in nasal airflow and resistance were produced by surreptitious substitution of 12–15 breaths of 79% He-21% O2 for air at rest and during exercise. The switch to He-O2 decreased airway resistance (anterior rhinomanometry) by approximately 30% at rest and 40–60% during exercise. He-O2 did not change nasal flow or AN activities significantly under resting conditions. In contrast, He-O2 increased nasal flow and decreased the AN electromyogram by 25–50% during exercise (P < 0.05). The results suggest that AN muscle activities during nasal breathing are regulated by mechanisms that track airway resistance or the level of flow turbulence. The increase in AN activities during exercise probably helps ensure nasal airway patency in the face of the considerable collapsing pressures that prevail under these conditions.

Abstract Objective To investigate the effects of nasal irrigation with sodium hyaluronate and surfactant solutions on mucociliary clearance time in patients with mild persistent allergic rhinitis. Methods A total of 120 patients diagnosed with mild persistent allergic rhinitis were enrolled in this prospective study. The patients were allocated randomly to the surfactant, sodium hyaluronate or isotonic saline (as a control) nasal irrigation group. The mucociliary clearance times and improvements in mucociliary clearance times were compared. Results Improvements in mean mucociliary clearance time were significantly greater in the surfactant and sodium hyaluronate groups than in the control group (p < 0.01). The mean post-treatment mucociliary clearance time of the surfactant group was significantly lower than that of the control (p < 0.001) and sodium hyaluronate groups (p = 0.03). Conclusion Surfactant and sodium hyaluronate nasal irrigation solutions may both be used as adjunctive treatments for allergic rhinitis. Surfactant nasal irrigation resulted in better mucociliary clearance times.
