Yes, HFOVn.

In our medical service, we have not yet begun that experience.

But we have some interesting references:

Yoder, B., Albertine, K. and Null Jr., D: High-frecuency ventilation for non-invasive respiratory suppert of neonates in Seminars in Fetal & Neonatal Medicine, xxx (2016) 1-12 (in press).

Mukerji, A., Singh, B., el Helou, S., Fusch, C., Dunn, M., Belik, J. and Shah, V. Use of Noninvasive High-Frequency Ventilation in the Neonatal Intensive Care Unit: A Retrospective Review in Amer J Perinatol 2015; 32(02): 171-176.

I have read about Nasal HFOV.. I'm still wondering though.. How can such a tiny tidal volume (in a HFOV) give through the nose and hoping it will open the lung? I think the tiny pressure will be just lost in the way, particularly if the baby open its mouth.. Please enlighten me.. ☺️☺️

Good point @Rizalya - I also wonder about the lung mechanical principles why this would work, to me this feels like a "HFNC 2.0"

But I have also heard about cases handled succesfully (post-extubation).

I guess there will be more publications coming out (and companies promoting it...)

For sure if you use small tidal volumes and the mouth open won't help like bubble CPAP you should close the mouth and apply the ventilation .Also the size  of the nasal prong or canula is very important to achieve good oscillation.
