At postsurgical evaluation between 3 and 6 months later, all patients were able to tolerate CPAP for 4 or more hours per night for 70% or more of the nighttime. The mean NOSE score improved significantly from 66.36 before surgery to 34.3 at postsurgical follow-up. Mean ESS score also improved, dropping from 10.45 before surgery to 4.98 at follow-up. The mean lowest nocturnal oxygen saturation also significantly increased by the postsurgical follow-up.
MCA1 and MCA2 also increased after surgery, which correlated significantly with a decrease in necessary CPAP titration pressure. “This improvement in the MCA correlated positively with the decline in the optimal CPAP pressure requirements and rendered non-adherent OSA patients tolerant to CPAP therapy,” study authors wrote.
... nasal surgery appears to improve sleep quality and reduce daytime sleepiness in patients with sleep-related breathing disorders.
Given the results of this and previous studies, “it seems that when combined with CPAP, surgical relief of nasal obstruction provides a remarkable improvement in subjective daytime sleepiness,” the authors concluded.

I believe a nasal airway examination should be a standard procedure for all CPAPers. Here is a summary of a study from a peer-reviewed journal.
