Vocal fold polyp: what to do when steroid injection fails to achieve adequate lesion reduction
This protocol applies to patients with a vocal fold polyp who have completed a first-line in-office steroid injection and whose lesion has not responded sufficiently — specifically, where a reduction in lesion size of more than 50% was not achieved.
Previous treatment & failure condition
The preceding first-line treatment — a low-dose submucosal triamcinolone acetonide injection into the vocal fold, performed as an awake in-office procedure — did not meet its primary goal: a reduction in vocal fold lesion size of more than 50%. Failure to reach this threshold is the escalation trigger for the current protocol.
Next-line approach (partial overview)
When the injection response threshold is not met, the next step is phonosurgical excision of the vocal fold polyp. Multiple surgical techniques are available; the appropriate approach is selected based on lesion characteristics and clinical context.
The complete technique selection algorithm and procedural details are in the full protocol below.

- As previously noted, with the exception of lesions affecting the patency of the airway or those in which the diagnosis of malignancy is entertained, the indication for surgical therapy is the presence of unacceptable vocal impairment despite compliance with medical treatment and appropriate voice therapy.
- The author's technique of choice is the subepithelial microflap, when feasible.
- A simple superficial excision, sparing the underlying uninvolved LP and minimizing the epithelial loss, is generally sufficient.
