[Ethisorb/Ethisorb durapatch for the transnasal duraplasty procedure?]

Area of Science:

• Neurosurgery
• Otolaryngology

Background:

• Rhinobasal dura defects pose a surgical challenge.
• Transnasal closure offers a minimally invasive approach.
• Autologous and alloplastic materials are available for repair.

Purpose of the Study:

• To evaluate the efficacy of Ethisorb and Ethisorb durapatch for transnasal closure of rhinobasal dura defects.
• To assess the safety and outcomes of this alloplastic repair technique.

Main Methods:

• Eight patients with rhinobasal dura defects underwent repair using Ethisorb or Ethisorb durapatch.
• A sandwich technique involved endocranial and endonasal application of the material.
• Nasal concha mucosa and fibrin glue were used for sealing.

Main Results:

• All eight patients achieved successful treatment outcomes.
• No persistent cerebrospinal fluid (rhinoliquorrhea) leaks were observed post-healing.
• The technique allowed for early detection of potential new leaks.

Conclusions:

• Ethisorb and Ethisorb durapatch are suitable alloplastic materials for endonasal dura defect repair.
• The materials' stiffness and moldability facilitate effective closure.
• This technique presents a viable alternative for managing substantial dura defects with cerebrospinal fluid leakage.
