Eligibility Inclusion Criteria: 1. Inclusion Criteria of Part A - Sign informed consent before the test to fully understand the purpose, process and possible adverse reactions of the test; - Age 18-75 years old (including the threshold), male or female; - Enroll in the clinical study of TQH2722 for chronic sinusitis with or without nasal polyps (study number TQH2722-II-02) and meet the following criteria "a" or "b" : 1. Subjects completed prescribed treatment as required and completed Part A end of study (EOS) visit; 2. The subjects withdrew early due to poor compliance or other objective reasons other than TQH2722-related AE, and completed the early exit interview according to the plan, and the influencing factors that led to the subjects' early termination of the main study treatment have disappeared/no longer affected the subjects' participation in the continuation study as assessed by the investigators and sponsors. Note: If protocol window period requirements are met, examination results from subject's main study EOS/ early exit visit may be used as screening/baseline examination for this study. - Subjects had used a more stable dose of nasal glucocorticoids (INCS) for more than 4 weeks prior to screening (for subjects who had used other INCS prior to screening than intranasal Mometasone furoate nasal spray (MFNS), subjects were willing to switch to MFNS during the study); - Subjects agree not to have a family plan for 6 months from the date of signing the informed consent to the last dose, and must use effective non-drug contraception with their sexual partners of childbearing age. 2. Inclusion Criteria of Part B - Sign informed consent before the test to fully understand the purpose, process and possible adverse reactions of the test; - Age 18-75 years old (including the threshold), male or female; - Enroll in the clinical study of TQH2722 for chronic sinusitis with or without nasal polyps (study number TQH2722-II-02) and meet the following criteria "a" or "b" : 1.

A deviated nasal septum leads to obstruction of at least one nostril 2. Persistent drug rhinitis; 3.
