As an essential part of facial reconstruction, silicone nasal prosthesis repair plays a crucial role in improving the appearance and function of patients who have suffered nasal defects due to various reasons such as trauma, burns, infections, congenital disorders, or surgical procedures. The recent release of the new public - strength ranking of silicone nasal prosthesis repair in New York City has drawn significant attention from patients, medical professionals, and the general public. This ranking provides valuable insights into the capabilities and reputations of different medical institutions and practitioners in this field.
Understanding Silicone Nasal Prosthesis
Properties of Silicone for Nasal Prosthesis
Silicone has become a popular choice for nasal prostheses due to its numerous advantageous properties. According to the research on "Nasal reconstruction with silicone using customised impression technique", the ideal properties for facial prosthetic materials are multifaceted. For silicone, it has excellent processing characteristics, including low viscosity, which allows for easy molding during the fabrication process. It also has an extended working time, enabling precise shaping and fitting of the prosthesis. The capability of intrinsic and extrinsic colorization is another important aspect, as it allows the prosthesis to closely match the patient's skin color, enhancing its aesthetic appearance. Additionally, it has a relatively low processing temperature, which is beneficial for maintaining the integrity of other components during fabrication.
In terms of mechanical or performance characteristics, silicone offers high tensile strength, high percent elongation, and an appropriate elastic modulus. This ensures that the prosthesis can withstand normal mechanical forces during daily use without easily breaking or deforming. It also has good dimensional stability, which means the shape of the prosthesis remains consistent over time. Moreover, silicone has resistance to chemicals and ultraviolet light, protecting it from damage and deterioration. In terms of patient accommodation properties, silicone is non - toxic and non - allergenic, ensuring the safety of the patient. It is easily cleansible, lightweight, and compatible with adhesives, which are important factors for patient comfort and usability.
Types of Nasal Defects Suitable for Silicone Prosthesis
Silicone nasal prostheses can be used to address a wide range of nasal defects. Patients who have undergone partial or total rhinectomy due to diseases such as adenoid cystic carcinoma, as described in the case study of "Nasal reconstruction with silicone using customised impression technique", can benefit from silicone prostheses. Trauma - induced nasal defects, whether from accidents or injuries, can also be effectively repaired with silicone. Congenital nasal deformities, which may affect the normal function and appearance of the nose, can be corrected or improved using silicone nasal prostheses. Some patients with complex nasal defects that extend onto the cheek, forehead, upper lip region, or into the mouth, as mentioned in the information about nasal prostheses from "Nasal Prosthesis - Prosthetic Nose | Wisconsin — Life - like Prosthetics", may require a mid - facial prosthesis made of silicone, which is designed in collaboration with dental specialists (maxillofacial prosthodontists) to provide effective solutions.
Process of Silicone Nasal Prosthesis Repair
Initial Assessment and Consultation
When a patient presents with a nasal defect and is considering silicone nasal prosthesis repair, the first step is usually an in - depth assessment and consultation. In institutions like Mount Sinai's division of facial plastic and reconstructive surgery, as described in "Rhinoplasty (Nose Job) NYC | Mount Sinai", patients start with an extensive consultation. During this process, medical professionals will carefully listen to the patient's concerns and goals. They will examine the patient's nasal anatomy, including the shape, size, and condition of the remaining nasal tissues. Photographs may be taken to document the current state of the nose and for future reference during the treatment planning process. They will also review the patient's medical history, including any previous surgeries, infections, or other relevant medical conditions. This comprehensive assessment helps the medical team to understand the specific needs of the patient and develop an individualized treatment plan.
Impression and Modeling
The next step is to create an impression of the nasal defect and adjacent tissues. In the case study of "Nasal reconstruction with silicone using customised impression technique", an impression was made of the defect and adjacent tissues using irreversible hydrocolloid impression material. Care was taken not to block the desirable undercuts as they are important for the mechanical retention of the prosthesis. Paper clips were attached on the wet surface of the impression material on the face, and dental plaster was applied over it to provide a rigid support for the impression. After that, a cast was obtained by pouring type III dental stone. Then, a custom acrylic tray was fabricated over this cast to achieve a functional impression of the tissues. The patient was asked to do various facial movements while making the functional impression to ensure that the prosthesis can fit well during normal use.
Once the functional impression is obtained, a wax - up of the final prosthesis is done on the cast using modeling wax. The wax pattern is adjusted according to the patient's facial symmetry and other aesthetic requirements. The patient may be asked to try on the wax prototype to ensure a natural contour and fit. Any necessary adjustments are made at this stage based on the patient's feedback.
Prosthesis Fabrication
After the wax pattern is finalized, the actual prosthesis fabrication begins. The wax pattern is secured back onto the final cast and flasked. After de - waxing, the nasal prosthesis is processed using medically graded silicone prosthesis material. Intrinsic staining is done using the intrinsic stains provided by the silicone manufacturer based on a trial - and - error method and then cured. This process helps to achieve the desired color and appearance of the prosthesis. After curing, de - flasking is done, and the prosthesis is retrieved. The excess silicone extending beyond the borders is removed, and extrinsic coloration is done to further match the skin color of the patient. The final contouring and matching are carried out to ensure that the superior and medial borders of the prosthesis are adapted as closely as possible to the point of contact with the eyeglass frames (if applicable), and the overall appearance of the prosthesis is natural and aesthetically pleasing.
Attachment and Adjustment
There are several methods for attaching silicone nasal prostheses. As mentioned in "Nasal Prosthesis - Prosthetic Nose | Wisconsin — Life - like Prosthetics", one method is medical adhesive attachment. Special medical adhesives are used to attach the prosthetic nose, and patients usually easily adjust to using them, similar to using other daily - care items like flossing or caring for contact lenses. Anatomical retention is another option, where the partial nasal prosthesis engages with the existing anatomy to stay in place securely. For example, after nose removal, the remaining opening may allow for the design of a prosthesis that slides into place and engages anatomical undercuts for secure attachment with little or no adhesive. In some cases, a prosthetic nose may be designed to attach to a dental device called an obturator. Craniofacial bone - anchored implants are also available for more secure attachment. These small titanium fixtures are surgically implanted during an outpatient hospital procedure, and after a 3 - 6 month healing period, the prosthesis can be snapped onto the implants using technovent magnets.
After the prosthesis is attached, the medical team will make further adjustments to ensure the fit and comfort of the patient. They will check the position of the prosthesis, the level of support, and the overall appearance. Any necessary fine - tuning is done at this stage to optimize the performance of the prosthesis.
