From what I have learned, there is not much of a middle ground for Central Sleep Apnea. Either one has it or not. I suffer from it. My father died from it after suffering from it untreated for 40 years. CPAP and BiPAP do not do much for Central.

I was not suggesting the nasal opening were the cause of your OSA (Obstructive Sleep Apnea). But, they may be a contributing factor. My small nasal openings do not effect my breathing in bed. It is when I am more upright that they get easily clogged up with just normal drainage.

But, I wonder if small nasal openings through the bony area contribute to the flesh (that the Breath Right pulls away) collapsing in ? Would widening the opening provide a wider structure for the flesh that falls into the airway ?
