[Use of L-shaped silicone prosthesis and expanded polytetrafluoraethylene to repair the nasal deformities after repair of unilateral cleft lip: report of 17 cases].

Purpose: To evaluate the effect of using L-shaped silicone prosthesis and expanded polytetrafluoraethylene (ePTFE) to correct the nasal deformities after repair of unilateral cleft lip in 17 cases.

Methods: After correction of the malposed nasal cartilages, a chip of ePTFE was added to the tip of the L-shaped silicone prosthesis, and sutured with 5-0 nylon thread, to consolidate and mold the nasal dorsum, tip, ala and nasal columella.

Results: Simultaneous use of L-shaped silicone prosthesis and expanded polytetrafluoraethylene could elevate the flat nasal dorsum, tip, ala and nasal columella, which improved the nasal contour significantly.
