The Myringotomy Knife, Blades Set at 90 & 120°, 6 1/4″ is a specialized otologic surgical instrument designed for precise and controlled incision during myringotomy and related ear procedures. The instrument features blades positioned at 90° and 120°, providing different working angles to help accommodate the surgeon’s preferred approach and the anatomical requirements of the operative field.
Myringotomy involves creating a controlled opening in the tympanic membrane to provide access to the middle ear or facilitate drainage when clinically indicated. Because the tympanic membrane is a delicate anatomical structure, an appropriate surgical knife is important for controlled incision and accurate instrument handling. The angled blade design of this myringotomy knife helps provide access within the external auditory canal while maintaining a practical working orientation.
With an overall length of 6 1/4 inches, the instrument offers useful reach for otologic procedures while allowing the surgeon to maintain controlled manipulation. The 90° and 120° blade angles provide versatility when approaching the tympanic membrane from different positions. This configuration can be particularly useful when anatomical access or visualization makes a straight cutting instrument less convenient.
The instrument is designed for professional ENT and otologic use and is typically manufactured from surgical-grade stainless steel. Stainless steel construction provides mechanical strength, corrosion resistance, and durability when the instrument is properly cleaned, maintained, and processed. Its smooth surface also facilitates routine cleaning and inspection as part of a validated surgical instrument reprocessing workflow.
The Myringotomy Knife is suitable for use in operating rooms, ENT procedure rooms, and otologic surgical instrument sets where precise tympanic membrane incision is required. Its specialized geometry supports controlled handling during delicate ear surgery and helps the surgeon work within the confined space of the external auditory canal.
Proper maintenance is important for preserving the instrument’s performance. Following each procedure, the knife should be cleaned promptly according to the healthcare facility’s validated instrument-processing protocol. Particular attention should be given to the blade areas and any joints or surfaces where biological material may accumulate. After cleaning, the instrument should be thoroughly inspected for cleanliness, structural integrity, and blade condition before sterilization.
When supplied as a reusable instrument and validated for the applicable sterilization method, the knife may be processed using an approved sterilization system, such as steam sterilization, according to the manufacturer’s instructions and facility protocols. Proper handling, drying, sterilization, and storage can help maintain the instrument’s service life and functional condition.
The Myringotomy Knife with 90° and 120° blades combines specialized blade angulation, practical length, and durable surgical construction for controlled ENT procedures. It is a useful addition to professional otology, myringotomy, tympanic membrane, and ENT surgical instrument sets.
