hello everyone,
I'm looking for advice or experiences regarding persistent breathing difficulties after uvulopalatal flap (UPF) surgery.
On January 26, 2026, I underwent a sleep study (PSG) at a local clinic and was diagnosed with moderate obstructive sleep apnea (AHI 22, minimum oxygen saturation 77%). I initially tried APAP therapy but couldn't tolerate it.
I subsequently underwent UPF surgery and tonsillectomy at Korea University Anam Hospital on July 23, 2026.
It has now been almost three months since surgery, and I have been experiencing persistent breathing difficulties. My main symptom is an inability to take a deep, satisfying breath, accompanied by a strong sensation of tightness or tension in my soft palate.
My surgeon suspects postoperative sensory changes, possibly involving the soft palate indirectly. However, I suspect that the uvula being folded and fixed upward during UPF may have restricted the natural movement of my soft palate, making inspiration difficult.
Interestingly, whenever the tension in my soft palate temporarily decreases, my breathing becomes noticeably easier. However, the discomfort eventually returns.
My operative report also mentions "uvula elongation," indicating that my uvula was elongated before surgery.
While reviewing the medical literature, I found several statements that seem relevant to my hypothesis:
1. Powell et al. (1996)
"In patients with excessively thick palates, the doubling over of the muscular uvula may interfere with palatal function"
A Reversible Uvulopalatal Flap for Snoring and Sleep Apnea Syndrome.
Sleep, 19(7), 593–599.
2. Zhou & Hsia (2015)
"There is no absolute contraindication, but relative contraindications include patients with excessively long or bulky soft palate or patients classified as Friedman stage III."
The Uvulopalatal Flap.
Operative Techniques in Otolaryngology–Head and Neck Surgery, 26(2), 78–84.
3. Verse, Pirsig & Maurer (2010)
"A too thick uvulopalatal flap may lead to dysphagia, articulation impediments, and obstructed breathing."
Palatal Surgery.
In Surgery for Sleep Disordered Breathing, 2nd edition, Springer.
Based on these references, I'm wondering whether my soft palate or uvula may have been too long or bulky for UPF, resulting in excessive tissue tension or restricted movement after surgery.
Most of my yawns get cut short before I can complete them. Only when I manage to yawn fully do I feel like I can take a deep, satisfying breath
I'm not suggesting that the surgery was performed incorrectly. I'm simply trying to understand whether the anatomical changes caused by UPF could be contributing to my breathing difficulties.
Has anyone experienced similar breathing difficulties or a sensation of restricted soft palate movement after UPF or UPPP surgery?
