Challenges in Nasal Cartilage Tissue Engineering to Restore the Shape and Function of the Nose.

The repair of nasal septal cartilage is a key challenge in cosmetic and functional surgery of the nose, as it determines its shape and its respiratory function. Supporting the dorsum of the nose is essential for both the prevention of nasal obstruction and the restoration of the nose structure. Most surgical procedures to repair or modify the nasal septum focus on restoring the external aspect of the nose by placing a graft under the skin, without considering respiratory concerns.

Objective diagnosis of internal nasal valve collapse by four-phase rhinomanometry.

Background: Internal valve collapse is a frequent cause of nasal obstruction but remains poorly understood and is sometimes treated inappropriately as a result. No functional or imaging test for the condition has been validated and the reference diagnostic technique is physical examination. The objective of this study was to evaluate the potential of four-phase rhinomanometry as a diagnostic test for internal valve collapse.

Combination of bioactive factors and IEIK13 self-assembling peptide hydrogel promotes cartilage matrix production by human nasal chondrocytes.

Nasal reconstruction remains a challenge for every reconstructive surgeon. Alloplastic implants are proposed to repair nasal cartilaginous defects but they are often associated with high rates of extrusion and infection and poor biocompatibility. In this context, a porous polymeric scaffold filled with an autologous cartilage gel would be advantageous.

A comparative retrospective study: hypoglossofacial versus masseterofacial nerve anastomosis using Sunnybrook facial grading system.

Introduction: The aim of our study is to compare the functional results between two surgical techniques for reanimation of facial paralysis: hypoglossal-to-facial versus masseteric-to-facial nerve anastomosis.

Methods: This is a retrospective study of 13 patients treated for complete facial paralysis in two medical tertiary centers. The patients were classified into two groups.
