The purpose of this paper was to investigate the impact of Methicillin Resistant Staphylococcus Aureus (MRSA) infection in the aetiology of pharyngo-cutaneous fistula (PCF) formation following total laryngectomy for advanced laryngeal cancer.

This was a retrospective uncontrolled case study series of 31 consecutive patients based in a single institution tertiary referral head and neck oncology centre.

Pharyngo-cutaneous fistulas (PCF) following total laryngectomy occurred in 10 (32%) patients. MRSA was identified in 80% of patients with a PCF compared to 9% of patients that did not develop a fistula (p = 0.0001255 Fisher exact test). MRSA infection (p = 0.00012) and previous radiotherapy (p = 0.00025) were the only significant factors found to be important in fistula formation on multivariate analysis. Post-operative infections such as cellulitis, chest infection and carotid fistula were also associated with MRSA infections.

MRSA infection following total laryngectomy for laryngeal cancer can lead to potential serious complications such as PCF. Patients who underwent total laryngectomy following radiotherapy failure are at a higher risk of acquiring MRSA.
