Summary
Vistafix (VXI) implants provide a safe and reliable method for retaining auricular prostheses. Patients reported high satisfaction and improved quality of life with this osseointegration technique.
Area of Science:
- Otorhinolaryngology
- Biomaterials Engineering
- Plastic Surgery
Background:
- Osseointegrated implants are increasingly used for auricular prostheses.
- Next-generation percutaneous osseointegrated titanium implants have advanced bone conduction hearing.
- The Vistafix system (VXI implant) applies this technology for auricular prosthesis retention.
Purpose of the Study:
- To evaluate the surgical procedure for VXI implant-retained auricular prostheses.
- To assess the clinical outcomes and patient satisfaction.
- To determine the safety and efficacy of VXI implants for auricular reconstruction.
Main Methods:
- Retrospective evaluation of 11 patients who received VXI implants between 2012 and 2017.
- Review of medical files for complications and revision surgery.
- Subjective outcome assessment using the Glasgow Benefit Inventory (GBI).
Main Results:
- 31 VXI implants were placed in 11 patients with no implant loss or need for revision surgery.
- Adverse skin reactions occurred in 13.0% of implants and 27.2% of patients, managed with antibiotic ointment.
- Average follow-up was 2 years and 7 months, with all patients showing a positive GBI score.
Conclusions:
- VXI implants are a safe and reliable option for auricular prostheses in patients with absent auricles.
- Patients experienced high satisfaction and improved quality of life.
- Further prospective studies with larger cohorts are recommended for statistical significance.

Attachment is vital for infant development, as warm social interactions support growth and well-being. In a classic 1958 study by Harry Harlow, the significance of warmth and comfort in forming attachments was examined. Harlow separated newborn monkeys from their mothers and provided two artificial "mothers": one made of cold wire and the other covered in soft cloth. Despite the wire mother offering food, the infant monkeys preferred the comfort of the cloth mother, demonstrating that...

01:24Attachment Styles

Jeffrey Simpson's attachment theory suggests that early caregiver relationships shape lasting patterns of behavior and emotional regulation, known as attachment styles. These patterns are organized along two key dimensions: self-esteem and interpersonal trust. The intersection of these dimensions produces four primary attachment styles that typically persist throughout life and significantly influence how individuals form and maintain relationships.Secure Attachment StyleIndividuals with a...

02:57Attachment of Sister Chromatids
4.0K
As cells progress into mitosis, the nuclear envelope breaks down, and the condensed chromosomes are exposed to the array of bipolar microtubules of the mitotic spindle. The kinetochore, a large, disc-shaped protein complex, is present at the centromere region of the sister chromatids and acts as a binding site for the microtubules. Usually, the plus-end of a single microtubule is embedded within the kinetochore. However, some kinetochores first establish lateral contact with the side-wall...

Attachment is a long-standing connection or bond with others. While Attachment Theory was conceived in developmental psychology to describe infant-caregiver bonding, it's been extended into adulthood to include romantic relationships.

01:28Relationship with Parents: Attachment

Parent-child interactions lay the foundation for how we understand relationships throughout life. These interactions are not uniform across families; instead, they are shaped by a range of environmental, emotional, and behavioral factors unique to each caregiver-child dynamic. Social psychologists study these early relationships to understand how patterns formed in infancy influence social functioning and interpersonal behavior in adulthood.Attachment Theory and Early Relational ModelsJohn...
