Abstract

Objective

Radiotherapy is considered a risk factor for pharyngocutaneous fistula after a total laryngectomy. This study aimed to analyse the impact of exclusive radiotherapy versus chemoradiotherapy and the time interval between radiotherapy and surgery on the risk of pharyngocutaneous fistula.

Method

This study was a retrospective revision of 171 patients treated with a total laryngectomy after radiotherapy or chemoradiotherapy.

Results

Pharyngocutaneous fistula occurred in 33 patients (19.3 per cent). Patients previously treated with chemoradiotherapy showed a non-significant higher pharyngocutaneous fistula rate compared with patients treated with radiotherapy (25.0 per cent vs 18.0 per cent; p = 0.455). Patients with a pharyngocutaneous fistula after chemoradiotherapy treatment required a surgical repair more frequently than patients treated with radiotherapy (p = 0.005). There were no significant differences in the pharyngocutaneous fistula rate depending on the time interval between radiotherapy and surgery (p = 0.580).

Conclusion

There were no differences in the pharyngocutaneous fistula rate after total laryngectomy depending on the previous treatment with radiotherapy or chemoradiotherapy, or depending on the interval between radiotherapy treatment and surgery.
