The Impact of Endonasal Endoscopic Sinus Surgery on Patients with Chronic Pulmonary Diseases

Introduction: The impact of endoscopic sinus surgery on bronchial asthma has been studied by several groups. According to the latest studies, patients with chronic obstructive pulmonary disease (COPD) seem to have frequent symptoms of chronic rhinosinusitis. Our study compares the impact of endoscopic sinus surgery on both the upper and lower airways of patients with bronchial asthma as well as those with COPD. Methods: This study includes 43 patients (bronchial asthma, n = 32, COPD, n = 11) undergoing surgical treatment for chronic rhinosinusitis at the ENT-Department, University of Homburg (Homburg, Germany). To assess the effect of sinus surgery, the Sino-Nasal Outcome Test 20 German Adapted Version (SNOT-20 GAV) and St. George’s Respiratory Questionnaire (SGRQ) were used both pre- and postoperatively. Results: Both SNOT-20 (p < 0.001) and SGRQ (p = 0.021) scores improved significantly after sinus surgery. The postoperative improvement in bronchial asthma and COPD was similar in both groups, indicating no difference of the diseases in regards to postoperative symptom improvement. There was no difference indicated in SNOT-20 GAV or SGRQ when grouping patients by polyps, aspirin (ASS) intolerance, allergies, eosinophilia or previous surgery. Conclusions: The treatment of chronic rhinosinusitis by sinus surgery may help to improve the therapy outcome of patients with bronchial asthma as well as patients with COPD

Augmented reality-enhanced navigation in endoscopic sinus surgery: A prospective, randomized, controlled clinical trial

Objective: Endoscopic sinus surgery represents the gold standard for surgical treatment of chronic sinus diseases. Thereby, navigation systems can be of distinct use. In our study, we tested the recently developed KARL STORZ NAV1 SinusTracker navigation software that incorporates elements of augmented reality (AR) to provide a better preoperative planning and guidance during the surgical procedure. Methods: One hundred patients with chronic sinus disease were operated on using either a conventional navigation software (n = 52, non‐AR, control group) or a navigation software incorporating AR elements (n = 48, AR, intervention group). Incidence of postoperative complications, duration of surgery, surgeon‐reported benefit from the navigation system and patient‐reported postoperative rehabilitation were assessed. Results: The surgeons reported a higher benefit during surgery, used the navigation system for more surgical steps and spent longer time with preoperative image analysis when using the AR system as compared with the non‐AR system. No significant differences were seen in terms of postoperative complications, target registration error, operation time and postoperative rehabilitation. Conclusion: The AR enhanced navigation software shows a high acceptance by sinus surgeons in different stages of surgical training and offers potential benefits during surgery without affecting the duration of the operation or the incidence of postoperative complications
