Objectives: Positive volume‐outcome relationships exist for diseases treated with technically complex surgery. Contemporary patterns of laryngeal cancer surgery by hospital and surgeon volume are poorly defined. Methods: The Maryland Health Service Cost Review Commission database was queried for hospital and surgeon laryngeal cancer surgical case volumes from 1990 to 2009. Results: Overall, 1,981 laryngeal cancer surgeries were performed by 288 surgeons at 41 hospitals. Cases performed by high‐volume surgeons increased from 19% in 1990 to 1999 to 35% in 2000 to 2009 (odds ratio [OR] = 3.0, P < .001), whereas cases performed at high‐volume hospitals increased from 33% to 39% (OR = 2.0, P < .001). High‐volume surgeons were more likely to perform total laryngectomy (OR = 1.7, P = .001) and neck dissection (OR = 1.7, P = .002). High‐volume hospitals were significantly associated with total laryngectomy (OR = 2.0, P = .003), neck dissection (OR = 1.8, P = .038), flap reconstruction (OR = 5.1, P = .021), prior radiation (OR = 3.0, P = .031), and increased mortality risk scores (OR = 3.2, P = .006). After controlling for other variables, laryngeal cancer surgery in 2000 to 2009 was associated with increased access to high‐volume surgeons (OR = 1.9, P < .001) and high‐volume hospitals (OR = 1.3, P = .040), a decrease in partial and total laryngectomy procedures (OR = 0.2, P < .001), an increase in neck dissection (OR = 2.2, P < 0.001), an increase in prior radiation (OR = 3.0, P < .001), increased case complexity scores (OR = 5.7, P < .001), and an increase in wound fistula or dehiscence (OR = 2.0, P = .015) compared with 1990 to 1999. Conclusions: The proportion of laryngeal cancer surgery patients treated by high‐volume surgeons and hospitals increased significantly in 2000 to 2009 compared with 1990 to 1999, with a decrease in laryngectomy procedures and an increase in wound complications. These findings may be due to changing trends in primary management of laryngeal cancer. Laryngoscope, 2011
