Changes in indications for endoscopic sinonasal surgery over 14 years

Changes in indications for endoscopic sinonasal surgery over 14 years. Objective: To assess how surgical indications for endoscopic sinonasal surgery have changed over time. Material and methods: The surgical indications of 1173 patients who underwent endoscopic sinonasal surgery between 1994 and 2007 were reviewed retrospectively. Results: Preoperative diagnoses were chronic sinusitis without nasal polyps in 511 patients (43.6%), chronic sinusitis with nasal polyps in 434 (36.9%), concha bullosa in 113 (9.6%), nasal mass in 66 (5.6%), and others in 49 patients (4.1%). Over 60% of patients had surgery for chronic sinusitis without nasal polyps between 1994 and 1999, whereas nearly 60% of patients who underwent surgery between 2001 and 2007 had chronic sinusitis with nasal polyps. Conclusions: Reasons for the decrease in the number of the patients with chronic sinusitis without nasal polyps and the increase in the number of patients with chronic sinusitis with nasal polyps might include: 1) Administration of maximal medical therapy; 2) Increased recognition of the possibility for false positive opacifications in computed tomography and increased understanding that not all anatomical variations predispose to sinusitis; 3) More careful “profit and loss” discussions with patients as our postoperative experience increased; 4) More patients with nasal polyps underwent endoscopic sinonasal surgery as surgical skills improved, and recurrences remained common.
