What are the outcomes of endolaryngeal laser versus total laryngectomy for T3 T4 laryngeal cancer?

No direct evidence for endolaryngeal laser versus total laryngectomy in T3 T4 laryngeal cancer was identified. Current guidance suggests total laryngectomy may offer better outcomes for T4 diseases, while organ-preserving approaches, including laser, could be viable for T3 cases, but this depends on individual tumor characteristics and patient circumstances.
