Do Mean Values of the Peak Inspiratory Nasal Flowmeter Vary According to the Severity, Direction and Type of Nasal Septum Deviation?

The aim is to investigate the contribution of the PNIF test in daily clinical practices in the objective evaluation of the early postoperative functional results of septoplasty and the effect of the severity, direction, and type of nasal septum deviation on mean PNIF values. Nasal septum deviation (NSDs) of the cases were grouped according to the Mladina classification and the severity of NSDs. An objective evaluation of the nasal airway was conducted via a peak flowmeter device in the preoperative and postoperative first month.
