Nasal and Tracheal Cytological Changes After Total Laryngectomy in Long-Term Survivors

Complete separation of upper and lower respiratory tract after total laryngectomy results in permanent effects on nasal cavities and tracheo-bronchial airways. Aim of this study is evaluating nasal and tracheal cytological alterations of mucosa in laryngectomy long-term survivors, analyzing the feasibility of scraping for cytological examination of tracheal mucosa

Nasal and Tracheal Microbial Colonization in Laryngectomized Patients

Complete separation of upper and lower respiratory tract after total laryngectomy results in loss of physiological nasal functions and presence of "unconditioned" inspired air in lower airways. Aim of this study is evaluating the presence of a microbial colonization of nasal cavities and trachea in laryngectomized long-term survivors.METHODS: Twenty-five laryngectomized patients underwent symptoms' anamnestic evaluation, endoscopic fiber optic nasal and tracheal examination, specimen collection for microbiological exam, and culture. Enrolled patients had at least a 2-year follow-up period in order to evaluate long-term microflora. RESULTS: Gram positive polimicrobic flora represented the main finding in nasal cavities and trachea (92% and 48% of patients, respectively). Other bacteria were non-fermenters Gram negative bacteria, Enterobacteriaceae and Staphylococcus aureus. The same microflora was demonstrated in nasal cavity and trachea in 5 patients (20%), while sterile nasal cavity and trachea were seen in 3 (12%) and 4 (16%) cases, respectively. No fungi were observed in nasal cavity and trachea. CONCLUSION: Nasal cavities and trachea of laryngectomized patients are colonized by nonpathogenic and/or potentially pathogenic bacteria, in absence of signs and symptoms of infection. Colonizer microflora should be kept in mind when a culture from nasal or tracheal swabs is needed in daily practice
