[Antibiotic prophylaxis in oncologic pharyngolaryngeal surgery: ceftriaxone versus clindamycin and gentamycin]

There are many papers comparing two antibiotic protocols for the profilaxis of head and neck infections after laryngeal surgery. We present one prospective and randomised study in 60 patients comparing the efficacy of two protocols. The comparison was between ceftriaxone versus the association of clindamicyn and gentamicyn. In our database we included the risk factors for infection, the surgical approach, the duration of surgery and the patient characteristics. We observed an incidence of 28% of infection, with a 23.3% in the clindamicyn + gentamicyn group and a 33.3% in the ceftriaxone group. The differences between the two groups were not statistically significant. In this study we observed a small difference between the amount of alcohol comsuption, the effectiveness of the surgical drainage, the surgical approach and the presence of wound infection. The difference was not statistical significant due to the small group of patients. The profilaxis was adequate for the total laryngectomy and cordectomy group, with a higher incidence of wound infection in patients treated with a supraglottic laryngectomy.
