1. Product Categories and Applications
This catalog details prosthetic devices used in otologic surgeries, specifically stapedectomy, stapedotomy, and tympanoplasty. The main categories include:
- Stapedoplasty Prostheses (SPL): For restoring middle ear function post-stapedectomy/stapedotomy.
- Tympanoplasty Prostheses (TPL): For reconstructive middle ear surgeries.
- Total Audio Prostheses (TAP) and Partial Audio Prostheses (PAP): For comprehensive or partial auditory reconstruction.
2. Materials and Components
The prostheses utilize biocompatible materials selected for durability and tissue compatibility:
- Metals: Platinum, Titanium (ASTM F67), Nitinol (superelastic nickel-titanium alloy).
- Polymers and Ceramics: AUDIO-PE (porous polyethylene), PTFE, AUDIO-HA (bioactive calcium hydroxylapatite ceramic), AUDIO-HAP (porous hydroxylapatite ceramic), Silicone.
- Composite Structures: Combinations such as Platinum/PTFE, Titanium/PTFE, and Nitinol/PTFE enhance mechanical and biocompatible properties.
3. Prosthesis Types and Features
- Platinum Prostheses: Available in piston diameters from 0.30 mm to 0.80 mm and lengths 3.00 mm to 6.00 mm; some models are trimmable for customized fit.
- PTFE and Silicone Loop Prostheses: Designed for stapedotomy/stapedectomy with notched or non-notched options; lengths 4.00 mm to 7.00 mm.
- Adjustable Cup Prostheses: Feature bioactive ceramic cups with platinum joints and PTFE columella; piston diameter typically 0.60 mm; lengths 4.00 mm to 5.00 mm.
- Titanium Bucket Handle Prostheses: Sizes with piston diameters 0.40 mm to 0.80 mm; total lengths 4.00 mm to 6.50 mm; functional lengths slightly shorter.
- Self-Crimping Prostheses: Titanium and Nitinol based for ease of implantation and secure attachment; piston diameters 0.40 mm to 0.80 mm; lengths 4.25 mm to 6.50 mm; some trimmable down to 4.25 mm.
- Trimmable Prostheses: Various models allow length adjustment from 7.00 mm down to ~4.00 mm for precise surgical fit.
4. Dimensions and Coding System
Each prosthesis is identified by a unique code (e.g., SPL 03.13.400), where the last digits indicate length in millimeters. Functional lengths are specified separately for certain types. Diameter specifications for pistons, loops, and columella guide selection based on patient anatomy.
5. Special Features and Accessories
- Nitinol Hooks: Available in small, standard, and large sizes based on anvil diameter; suffixes "P" (small) or "G" (large) added to product codes.
- Anvil Measurement Device: Code SPL 03.56, used intraoperatively for precise sizing.
- Adjustable Russo-Sanna Pistons: Titanium wire with PTFE trimmable stems; lengths 7.00 mm to 11.00 mm; allow intraoperative length adjustment.
6. Materials Properties and Biocompatibility
Materials are chosen for long-term stability and tissue integration. Platinum, titanium, and bioactive ceramics ensure biocompatibility. Porous polyethylene and PTFE provide inertness and compatibility. Nitinol offers superelasticity, enhancing surgical handling and fixation.
7. Recommendations and Usage Notes
- Multiple sizes and diameters accommodate patient-specific anatomy.
- Trimmable designs enable intraoperative length customization for optimal fit and function.
- Prosthesis selection should consider surgical technique, anatomy, and desired outcomes.
8. Additional Prosthesis Lines (AUDIO and TITANIUM Brands)
