Safety and efficacy of functional laryngectomy for end-stage dysphagia

Objectives/Hypothesis

To evaluate functional outcomes and complication rate after total laryngectomy (TL) for dysfunctional larynx with end-stage dysphagia.

Study Design

Retrospective chart review.

Methods

Chart review was performed on all patients who underwent TL from January 2008 to July 2016 at a single tertiary academic medical center. Patients who underwent TL for dysfunctional larynx without preoperative evidence of malignancy were included. Main outcome measures were post-TL functional swallowing and speech outcomes, and complication rate.

Results

The study included 19 patients from a cohort of 278 consecutive patients. All patients were previously treated with radiotherapy (RT), whereas 13/19 (68%) previously received chemoradiotherapy. The median time from RT to TL was 10.98 years (range, 0.67–23.94 years). Aspiration was evident preoperatively in 17/19 (89%) patients, with 11 experiencing recurrent aspiration pneumonia. Seventeen of 19 (89%) patients were nil per os (NPO) requiring enteral nutrition. Six of 19 (32%) patients had surgical complications, including three (16%) pharyngocutaneous fistulas. At 3-month and 1-year postoperative follow-up, there was significant improvement in mean Functional Oral Intake Scale (FOIS) score and aspiration, recurrent pneumonia, enteral nutrition, and NPO status rates (P < .05). At 1-year follow-up, no patients were NPO, and only one patient required gastrostomy tube supplementation. Mean FOIS score increased from 1.3 to 6.1 (P = .001). Eight of 13 patients (62%) were actively using a tracheoesophageal prosthesis at 1-year follow-up.

Conclusions

Laryngectomy for dysfunctional larynx eliminates the morbidity of aspiration while improving diet and reducing gastrostomy tube dependence with an acceptable complication rate.
