Tiny hole in septum skin on right nostril roughly 1mm. Just looks like missing mucosa membrane. Advice?

Hello and thank you for your question.  The
best advice you can receive is from an in-person consultation.  An intranasal speculum exam will be able to tell more about your possible septal perforation.   Make sure you specifically look
at before and after pictures of real patients who have had this surgery
performed by your surgeon and evaluate their results.   The most
important aspect is to find a surgeon you are comfortable with. I recommend
that you seek consultation with a qualified board-certified plastic surgeon who
can evaluate you in person.
Best wishes and good luck.

Thank you for the questions Shelly. Is the perforation something that your surgeon told you about or something that you can see? A 1mm perforation (micro-perforation) is very small would be difficulty to visualize yourself.  If this in the front of your septum it may cause crusting, bleeding, or whistling. If it is in the back, a septal perforation will usually not cause any functional issues. 
A single event or recurrent trauma can lead to a septal perforation. The tip of a nasal spray bottle, picking scabs, blowing forcefully, cocaine abuse, decongestant abuse, or surgery are all traumatic causes of a perforation. It may or may not heal, but conservative measures (ointment) and avoiding future trauma can only help. At minimum, the skin (mucosa) should be healthier. This is only general advice and your care should be directed by your surgeon and the diagnosis confirmed. 
There are surgical measures to repair a hole if necessary, but you should see someone that has experience in this procedure and is comfortable with these repairs. A risk of surgical repair is enlargement of the perforation and incomplete closure is possible. I hope this helps. Take care.
