Rehabilitation of swallowing with polydimethylsiloxane injections in patients who underwent partial laryngectomy.
BACKGROUND
We conducted this longitudinal prospective study to illustrate a surgical technique for swallowing rehabilitation of patients after partial laryngectomy.


METHODS
Nine patients with persistent swallowing impairment after partial laryngectomy were included in the study. Evaluation of swallowing was performed by fiberoptic endoscopic evaluation of swallowing (FEES), and was quantified using 2 scales: a dysphagia score and a modified penetration-aspiration scale. The site of bolus inhalation was identified. Polydimethylsiloxane (PDMS) was injected into the neoglottis to fill these passages, and to obtain a certain continence of the organ.


RESULTS
Mean follow-up was 25 months (range, 5-39). All patients showed an improvement both in the dysphagia score and in the modified penetration-aspiration scale. Average improvement was 2.6 points in the dysphagia score (p = .0042) and 2.1 points in the modified penetration-aspiration scale (p = .0043).


CONCLUSIONS
PDMS injection can be considered as an option in surgical rehabilitation of swallowing in patients who underwent partial laryngectomy.
