Abstract In cholesteatoma surgery, precise tissue resection is important, as the diseased tissue needs to be completely removed while preserving the ossicular chain to prevent recurrence and hearing loss. The ability to precisely ablate tissue using a pulsed \(445 nm\) diode laser operating in single-trigger mode was investigated. Single laser pulses with a duration of \(100 ms\) were applied with a power ranging from \(0.5 \text{to} 4 W\) via a multimode optical fiber.
