The use of the nasoseptal flap has revolutionized endoscopic skull base surgery, making the procedures more effective and with lower morbidity compared to the traditional route. However, although mainly transient nasal morbidities were observed, in some cases, permanent hyposmia and anosmia resulted. An improvement in this technique is therefore necessary to provide a better quality of life for the patient, reducing potential complications.

This study demonstrated that in an animal model of sinusitis that does not disturb the sinus directly osteitis occurs in the affected sinus and that it also affects the contralateral side.

The proposed model is technically simple to perform, it is similar to the rhinogenic model in human beings, and it is highly efficient to reproduce an acute bacterial sinus infection.

Introduction Coronavirus disease 2019 (COVID-19) has claimed millions of lives. Adequate protection of the professionals involved in patient care is essential in the battle against this disease. However, there is much uncertainty involving safety-relarted topics that are of particular interest to the rhinologist in the context of COVID-19. Objective To evaluate the current evidence regarding three safety-related topics: mask and respirator use, performance of nasal endoscopic procedures, and use of topical nasal and intranasal medications (saline irrigation and nasal corticosteroids). Methods A literature review was performed on the PubMed, Scopus, and Cochrane databases, with standardized search queries for each of the three topics of interest. Results In total, 13 articles on mask use, 6 articles on the safety of nasal corticosteroids, 6 articles on the safety of nasal endoscopic procedures, and 1 article on nasal irrigation with saline solution were included in the final analysis. Conclusion N95 respirators are essential for the adequate protection of otolaryngologists. If reuse is necessary, physical methods of sterilization must be employed. No evidence was found to contraindicate the use of nasal corticosteroids, whether acute (in the management of sinonasal inflammatory conditions) or continued (in patients who use them chronically). Nasal irrigation with saline solution apparently does not increase the risk in the context of COVID-19. Nasal endoscopic procedures should only be performed after testing the patient for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), and the surgical team must wear full personal protective equipment to prevent aerosol exposure.
