Abstract

BACKGROUND AND OBJECTIVES: To predict postoperative pulmonary complication in patients with conservative laryngectomy, variable factors such as pulmonary function test (PFT) have been reported. Therefore, we reviewed the relationships between postoperative pulmonary complications and preoperative risk factors including the parameters of PFT.
PATIENTS AND METHOD
From 1997 Jun. to 2005 July., conservative laryngectomy was performed under diagnosis of laryngeal cancer in 36 patients. The factors related to age, history of lung diseases, the parameters of PFT (FEV1, FEV1/FVC and FVC), and the types of surgery were analyzed to evaluate the postoperative pulmonary complication. We used a retrospective analysis of medical records and Fisher exact method to verify the relationships between preoperative risk factors and the pulmonary complications.
RESULTS
8 patients had postoperative pulmonary complication. Age, history of lung diseases and PFT parameters had no statistical significance. Among them, 7 patients and 1 patient had takensupracricoid laryngectomy and supraglottic laryngectomy, respectively. Supracricoid laryngectomy cases had more significant postoperative pulmonary complications than vertical partial laryngectomy cases.
CONCLUSION
Age, the history of lung diseases, and parameters of PFT had no predictable value for postoperative lung complications. In the comparison between the surgery types, only supracricoid laryngectomy cases had statistical increase of postoperative pulmonary complications.
