The 10-Item Standardized Cosmesis and Health Nasal Outcomes Survey (SCHNOS) for Functional and Cosme

Moubayed SP, Ioannidis JPA, Saltychev M, Most SP. The 10-Item Standardized Cosmesis and Health Nasal Outcomes Survey (SCHNOS) for Functional and Cosmetic Rhinoplasty. JAMA Facial Plast Surg. 2018 Jan 1;20(1):37-42. doi: 10.1001/jamafacial.2017.1083. PMID: 28880988; PMCID: PMC5833673.


Congrats to Miguel for having the vision to start this group!

I have chosen for paper of the day the original creation/psychometric validation study of the Standardized Cosmesis Health Nasal Outcomes Survey or SCHNOS (2017). I acknowledge that there are other QOL PROMS out there, including by members of this group, and I encourage the use of at least one of them in your practice. My bias, of course, is to this one so I will present it to you for use.

The SCHNOS measures aesthetics, function, and has a psychosocial component in just 10 questions. Importantly, the SCHNOS has been extensively validated psychometrically, as one of two my co-authors (Ioannidis and Saltychev) are world leaders in clinical research and psychometric evaluation of PROMs. This is very important, as if not done properly, you may not be measuring clinically useful data with your PROM. I have made this mistake myself with prior scales (RHINO). The SCHNOS has been shown to be useful as an indicator of BDD as well as useful for measuring likelihood to seek revision later (see refs).

The SCHNOS has been advocated as one of the PROMs to use by the US Rhinoplasty Work Group, a multispecialty group whose advocacy paper will be coming out soon in PRS.

The SCHNOS has been translated and validated into multiple languages (French, Spanish, Portuguese, Turkish, Korean, Persian/Farsi, Arabic)….and more validation studies are underway.

If you are interested in working on a translation study, please message me.

In addition to the paper, I’m sending out a PDF with all of the existing translations FREE FOR YOUR USE. If you use in any study, simply reference the original study and the translation study.

The scoring methodology is included, as well as the multiple references for psychometric validation and rhinoplasty studies that use it.

In your practice you will find the use of PROMs invaluable…I feel like I’m flying blind if I go to see a patient in the office without knowing their SCHNOS scores…it gives me a handle on their concerns before I walk into the room.

Please consider this simple 10 question PROM for your practice, so that we may all start ‘speaking the same language’ when it comes to our results quantitatively.

If you have any questions about use of this PROM, please contact me directly.
