Reduced hypopharyngeal muscle strength in patients with dysphagia symptoms after anterior cervical discectomy and fusion
Authors' conclusion
Post-ACDF dysphagia symptoms were associated with reduced hypopharyngeal contractile pressure.
Study context
- Population
- Patients within one year after anterior cervical discectomy and fusion (ACDF)
- Participants
- 43 patients
- Exposure
- Dysphagia symptoms vs no dysphagia symptoms after ACDF
- Dysphagia symptomsn = 29
- Without dysphagia symptomsn = 14reference
- Outcome
- Pharyngeal contractile function on high-resolution impedance manometry (HRIM) (hypoPeakP, SRI) and videofluoroscopy
Main finding
As reported in the abstract
Hypopharyngeal mean peak pressure (hypoPeakP), thin liquid (IDDSI level 0)
Observational data: associations, not effects.
Further findings
hypoPeakP, extremely thick liquid (IDDSI level 4)
Median
| Outcome | Dysphagia symptoms | Without dysphagia symptoms |
|---|---|---|
| Swallow Risk Index (SRI), thin liquid (IDDSI level 0) | 18.60 | 4.30 |
Swallow Risk Index (SRI), thin liquid (International Dysphagia Diet Standardisation Initiative (IDDSI) level 0)
- Significantly higher SRI with dysphagia symptoms
hypoPeakP, extremely thick liquid (IDDSI level 4)
- Significantly lower hypoPeakP with dysphagia symptoms
SRI, extremely thick liquid (IDDSI level 4)
- SRI did not differ significantly between groups
Safety
Aspiration (Penetration-Aspiration Scale (PAS) score ≥ 6)
- No aspiration events observed
