I'm no surgeon, but it would unlikely cure your OSA (then again, I might be wrong). It should help you breathe easier through your nose though I'm only saying this due to my physiology background of OSA.
Most surgery to try and cure OSA is performed around the upper airway because, as I said, this is the site of collapse. However, I have seen many unsuccessful operations. In some patients, their OSA is worse following surgery!
Well that kills my option of saving surgery for later.
Now, about that gastric bypass and plastic surgery.
Supportive Data?

I thought I might add to this thread.
This was a study published back at the start at the year. In this study, the aurhors looked at the effect of stretching the trachea (tracheal traction) on airway collapsibility and surrounding tissue pressure in anaethetised rabbits. This study again confirms how important airway tension is in regards to airway collapsibility. It also goes into a bit of detail about tissue pressure. I have explained a bit about this in this thread (post 11).

STUDY OBJECTIVES: To investigate the mechanisms via which lung volume related caudal tracheal traction decreases upper airway collapsibility. DESIGN: Acute physiological study. PARTICIPANTS: 20 male, supine, anesthetised, tracheostomised, spontaneously breathing, NZ white rabbits fitted with a sealed face mask. SETTING: N/A. MEASUREMENTS AND RESULTS: Upper airway extraluminal tissue pressure (ETP) was measured in the lateral (ETPlat) and anterior (ETPant) pharyngeal walls (pressure transducer tipped catheters). Graded traction was applied to the isolated upper airway (n = 17, 0-140 g). Subsequently, inflation and deflation was performed (with and without traction, 48 g, n = 13) with measurement of intraluminal pressure. Upper airway transmural pressure (PTM) was calculated (at closure and reopening) for both ETP sites (PTMlat and PTMant, respectively). A traction force of 144 g decreased ETPlat from 2.6 +/- 0.7 cm H2O (mean +/- SEM) to 2.1 +/- 0.7 cm H2O and ETPant from 1.1 +/- 0.4 cm H2O to 0.8 +/- 0.4 cm H2O (both P < 0.001). Increasing traction decreased closing and reopening pressures by 1.4 +/- 0.2 cm H2O for 48 g of traction (n = 13, P < 0.0001). In addition, 48 g of traction decreased ETPlat (at closure and reopening) by 0.2 +/- 0.05 cm H2O (P < 0.0001), and decreased ETPant by 0.5 +/- 0.1 cm H2O at closing pressure and 0.8 +/- 0.1 cm H2O at reopening (both p < 0.0001). Thus, for 48 g of traction, PTMlat (at closure and reopening) fell by 1.1 +/- 0.2 cm H2O and PTMant (reopening only) fell by 0.9 +/- 0.3 cm H2O (all P < 0.0001). CONCLUSIONS: Since tracheal traction decreased PTMlat and PTMant by a greater amount than ETPlat and ETPant, we conclude that the decrease in upper airway collapsibility mediated by lung volume related caudal tracheal traction is partially explained by reductions in ETP.

... and so where does one get tracheal reduction surgery and how much does it cost?

Geeze, Roberto. At least use the correct term for that kind'a surgery!
It's a
trachie tuck!!

Ok ok ... but is it covered by regular insurance or do you have to have a special rabbit insurance?

This is a cool thread, and I do not mean to hijack it, but...I guess I AM going to try. Before I do, thank you for posting such a complete report and one that is so interesting to us, Split. (If I may address you by your "first" name!)
The rabbit topic immediately reminded me of this:
How does one catch a unique rabbit?
Answer: Unique up on him! Of course! 
OK, I'll be around the corner...

Hmmm - I am definitely post-menopausal and overweight (after some months on prednisone) and have mild-to-moderate OSA. On the other hand, I have a friend who is post-menopausal and *very* thin and has severe OSA. Go figure!

I think that split needs to study apnea in giraffes ... they are at greater risk for the condition than little fat bunny rabbits.

lol...I'll give you points for that one!

Thanks to Padacheek, here's a link that talks about tracheal surgery. I really don't know what this surgery does...

Sounds like tracheal chiropractics rather than a surgical tuck ... so let me guess, Dr. Zhou stretches your neck into that of a giraffe so that the throat stays nice and tight.

I actually think this group are suggesting that caudal tracheal displacement i.e. strecthing??? causes these medical conditions. Seems a bit vague to me....
"
Trachea Caudal Displacement (TCD) induced chronic intermittent hypoxia through Silent Upper Airway Resistance Syndrome (SUARS) and Frequent & Recurrent Upper Airway Collapse Syndrome (FRUACS) as a new fundamental physio-pathological mechanism, as one of the main causes, for mild to moderate but prolonged hypoxia for most illness & diseases.
Dr. Jin Zhou also developed an innovative clinical therapy
to eliminate TCD and chronic intermittent hypoxia, to enhance or optimize human innate immune functions by employing human upper airway defensive reflexes and volitional resuscitation inherited or observed from autoresuscitation or spontaneous recovery."

You know, sometimes researchers get so involved in the defined terms of their studies that it borders on the ridiculous.
Maybe there should be a simplification of terms movement.

I have it on good "authority" that we stretch back...

This must be where Dr. Zhou got the idea from ... or is it where you got your research idea from?
