In particular, the Ralstonia genus was significantly dominant in the clinically healthy subjects. Additional pyrosequencing data from 32 subjects (healthy participants: n=15, AR patients: n=17) revealed a greater abundance of Staphylococcus epidermidis, Corynebacterium accolens, and Nocardia coeliaca, accounting for 41.55% of mapped sequences in the nasal mucus of healthy participants. Dysbiosis of the nasal microbiome was more pronounced in patients with AR, and Staphylococcus aureus exhibited the greatest abundance (37.69%) in their nasal mucus, in association with a positive response to house dust mites and patients' age and height.</p><p><strong>Conclusion: </strong>This study revealed alterations in the nasal microbiome in the nasal mucus of patients with AR at the levels of microbial genera and species.

Four ears showed perforation of the tympanic membrane after TM. Among the remaining 17 ears, 15 ears underwent ventilation tube insertion before BDET, while two ears underwent ventilation tube insertion and BDET simultaneously. Although none of the patients were capable of the Valsalva maneuver before BDET, 13 (62%) were able to perform the Valsalva maneuver successfully after BDET. When evaluating the tympanic membrane status at the latest follow-up, ventilation tubes were still present in eight ears. In the other 13 ears, intact tympanic membranes were present in nine out of 11 ears n the successful Valsalva group, whereas none of them were intact in the unsuccessful Valsalva group (P=0.014). The successful Valsalva group after BDET showed an improved air-bone gap of 8.9±12.4 dB, while the unsuccessful Valsalva group showed an aggravated air-bone gap of 3.8±11.8 dB at 1 year after BDET; this difference was statistically significant (P=0.031).</p><p><strong>Conclusion: </strong>The Valsalva maneuver could be performed successfully after BDET by 62% of patients with COM and ET dysfunction.
