Objective:The aim of this study was to conduct a cost analysis in patients treated with partial laryngectomy surgery due to laryngeal carcinoma.Methods:The length of stay, complication rates, decannulation time, time to initiate oral nutrition, costs of examination, medication costs and total cost were assessed by investigating the records and bills of 26 patients with larynx squamous-cell carcinoma treated with frontolateral, supraglottic and supracricoid laryngectomy surgery in the Ear-Nose-Throat Clinic of the Şişli Etfal Research and Training Hospital between January 2007 and December 2011.Results:Frontolateral laryngectomy was performed in 11 of 26 patients, supraglottic laryngectomy was performed in 8 of these patients and supracricoid laryngectomy was performed in 7 of these patients. Complications were observed in one of these 26 patients. When the costs of diagnostic tests/treatments of these three surgical methods were compared, supracricoid laryngectomy was found to be the most expensive method (p<0.05). Drug costs in this set of patients were significantly higher than in the frontolateral and supraglottic laryngectomy group (p<0.05). The total cost of the supracricoid laryngectomy group was significantly higher than that of the supraglottic and frontolateral laryngectomy group (p<0.05). Length of stay in the supracricoid laryngectomy group was significantly higher than that of the frontolateral and supraglottic laryngectomy group (p<0.05). In terms of decannulation times, although there was no significant difference between the supracricoid and supraglottic laryngectomy groups, the decannulation time was significantly lower in the frontolateral laryngectomy group (p<0.05). While the initiation time of oral nutrition was longest in the supracricoid and supraglottic laryngectomy groups, there was no significant difference between them. The initiation time of oral nutrition was significantly lower in the frontolateral laryngectomy group (p<0.05).Conclusion:The length of stay following partial laryngectomy due to squamous-cell carcinoma of the larynx can be prolonged due to the longer decannulation time and the longer initiation time of oral nutrition. To overcome these problems, particularly in supracricoid laryngectomy, action to prevent complications and precautions that can be taken during surgery will seriously reduce costs.
