Epistaxis01:30

Epistaxis

867
Epistaxis, or nosebleeds, occurs when small, swollen blood vessels in the nasal mucous membrane rupture. Typically, the anterior septum is the primary site of occurrence.
Etiology
Possible causes of this condition include high blood pressure, trauma, low humidity, upper respiratory tract infections, allergies, foreign bodies, nasal inhalation of corticosteroids or illicit drugs, excessive use of decongestant nasal sprays, facial or nasal surgery, anatomic malformation, tumors, or systemic...

Nose and Nasal Cavity01:24

Nose and Nasal Cavity

17.1K
The nose is composed of an observable exterior segment (external nose) and an internal segment within the skull known as the nasal cavity (internal nose). The external nose, visible on the face, consists of a framework of bone and hyaline cartilage enveloped in skin and muscle and lined with a mucous membrane. This structure is supported by the frontal bone, nasal bones, and maxillary bone and is supplemented by a cartilaginous framework comprising the septal nasal cartilage, lateral nasal...

Summary

A novel technique uses polyester (Dacron) felt to secure nasal implants, promoting fibrotic tissue growth. This method effectively treats saddle nose deformity and maxillary retrusion with minimal complications over 15 years.

Area of Science:

  • Plastic Surgery
  • Biomaterials Science
  • Regenerative Medicine

Background:

  • Nasal implants require stable fixation to prevent migration and ensure optimal aesthetic and functional outcomes.
  • Traditional methods may have limitations in achieving long-term stability or can lead to complications.
  • Polyester (Dacron) felt offers potential as a biocompatible material for implant fixation.

Purpose of the Study:

  • To introduce and evaluate a new method for immobilizing nasal implants using polyester (Dacron) felt.
  • To assess the efficacy and safety of this technique in correcting nasal deformities.

Main Methods:

  • Utilizing sewn polyester (Dacron) felt to create a robust fibrotic reaction around nasal implants.
  • Application of the technique in cases of saddle nose deformity and maxillary retrusion (flat nasal tip).

Main Results:

  • The polyester (Dacron) felt effectively immobilized nasal implants by stimulating a strong fibrotic response.
  • The method demonstrated successful application in correcting saddle nose deformity and maxillary retrusion.
  • Over a 15-year period and in a large patient cohort, complications were limited to a temporary inflammatory reaction in only 5% of cases.

Conclusions:

  • Sewn polyester (Dacron) felt is a safe and effective method for immobilizing nasal implants.
  • This technique offers a reliable solution for correcting complex nasal deformities with a low complication rate.
  • The induction of fibrotic reaction by Dacron felt contributes to long-term implant stability.
