The Role of Surgery in Treating Nasal Obstruction to Control Asthma

Advances in co-pathogenesis of the united airway diseases

According to the concept of "united airway diseases", the airway is a single organ in which upper and lower airway diseases are commonly comorbid. A range of inflammatory factors have been found to play an important role in the chain reaction of upper and lower airway diseases. However, the amount of research on this concept remains limited. The underlying mechanism of the relationship between typical diseases of the united airway, such as asthma, allergic rhinitis, and chronic sinusitis, also needs to be further explored. This review highlights the interaction between upper and lower respiratory diseases gathered from epidemiological, histoembryology, neural mechanistic, microbiological, and clinical studies, revealing the relationship between the upper and lower respiratory tracts.

Management of Patients with Severe Asthma and Chronic Rhinosinusitis with Nasal Polyps: A Multidisciplinary Shared Approach

Chronic rhinosinusitis (CRS) is one of the most frequent comorbidities associated with asthma and it contributes to an amplified global disease burden in asthmatics. CRS prevalence is much higher in asthmatic patients compared to the general population and it is more frequently related to severe asthma, especially in presence of nasal polyps (chronic rhinosinusitis with nasal polyps, CRSwNP). Moreover, asthma exacerbation has a higher occurrence in CRSwNP. From a pathologic point of view, CRS and asthma share similar and connected mechanisms (e.g., type-2 inflammation). A multidisciplinary approach represents a crucial aspect for the optimal management of patients with concomitant asthma and CRSwNP and improvement of patient quality of life. An Italian panel of clinicians with different clinical expertise (pulmonologists, ear, nose and throat specialists, immunologists and allergy physicians) identified three different profiles of patients with coexisting asthma and nasal symptoms and discussed the specific tracks to guide a comprehensive approach to their diagnostic and therapeutic management. Currently available biological agents for the treatment of severe asthma act either on eosinophil-centered signaling network or type-2 inflammation, resulting to be effective also in CRSwNP and representing a valid option for patients with concomitant conditions.

Pediatric turbinate radiofrequency ablation improves quality of life and rhinomanometric values. A prospective study

OBJECTIVE

turbinate surgery in pediatric patients is gradually increasing in popularity amongst pediatric otolaryngologists. However, despite this, there is scarce information regarding this surgical procedure in children. The present research is designed with the aim of assessing changes in nasal resistance, nasal airflow and quality of life in pediatric patients undergoing turbinate radiofrequency ablation.

METHODS

A prospective uncontrolled intervention clinical trial design was followed. Children between 4 and 15 years old undergoing turbinate radiodiofrequency ablation (TRA) were consecutively selected. Children were examined preoperatively and 1, 3, 6 and 12 months after turbinate surgery. Anterior active rhinomanometry with and without nasal decongestant and examination of the turbinates and adenoid size were carried out in each follow-up visit. The SN5 quality of live survey was answered by parents.

RESULTS

81 children were included, 28 with associated adenoidectomy. A significant improvement in quality of life was demonstrated since the first month after TRA. Regarding nasal resistance, there was an improvement 1 month after surgery, but it only reached statistical significance for the whole sample (p < 0.001)) and for the cohort of isolated turbinate surgery (p < 0.001) at 3 months, while the values for the cohort of children who underwent adenoidectomy reached significance at 6 months after surgery (p = 0.04). The difference in nasal resistance before and after decongestant was compared to the change in nasal resistance after surgery. It demonstrated a strong correlation with the change in nasal resistance at 1 month (R = 0.985; p < 0.001), 3 months (R = 0.995; p < 0.001), 6 months (R = 0.98; p < 0.001) and 12 months (R = 0.98; p < 0.001) after surgery.

CONCLUSIONS

turbinate surgery in pediatric patients seems to be a safe procedure which objectively and subjectively improves the symptoms of children suffering from nasal obstruction.
