This is an Ostrum Antrum Backbiting Punch, a highly specialized instrument used in otolaryngology (ENT) and sinus surgery. It features a long, slender shank with right-angled jaws designed to “bite” and remove small portions of bone or soft tissue in the nasal cavity and maxillary sinus. The scissor-style ring handles provide precise control, while the strong biting mechanism ensures clean and accurate cuts. Constructed from surgical-grade stainless steel, this instrument offers durability, corrosion resistance, and safe sterilization for repeated use. The Ostrum Backbiting Punch is an essential tool in functional endoscopic sinus surgery (FESS), polyp removal, and maxillary sinus interventions.
