Correction of Depressed Nasal Base and Piriform Aperture Using Polyethylene Implants

Lower midface concavity due to depressed nasal base and pyriform aperture may be aesthetically displeasing. A relative deficiency in lower midface projection may be congenital or acquired, particularly after cleft surgery and trauma. People with normal occlusion associated with lower midface concavity due to depressed nasal base and pyriform aperture can be corrected with an autologous bone graft or artificial implants. The authors performed paranasal augmentation with an alloplastic implants using a porous polyethylene implants(Medpor(R)) on 430 patients who had visited authors' hospital for aesthetic correction of lower midface contour from January 2000 to June 2009. 425 patients were satisfied with the outcome, which gave them a natural contour. Complications such as dislocation, displacement, infection and extrusion were not observed. Only five patients had their implants removed due to displeasing and foreign body sensations. Alloplastic augmentation in the paranasal area is a very easy procedure and can simulate the visual effect as that of maxillary advancement osteotomy. Paranasal augmentation using a porous polyethylene implants(Medpor(R)) in patients having lower midface concavity with normal occlusion can contribute to the enhancement of the lower midface contour.

Lower Blepharoplasty: In and Out Complementary Technique

PURPOSE: Traditional transcutaneous incision and transconjunctival incision methods are commonly used in the lower blepharoplasty. The transconjunctival method leaves no visible scars nor does it change the shape of lower eyelid contour and the surgical technique is not difficult. However removal of excess baggy skin is not possible through this method. Therefore, the transconjunctival incision method is useful only for patients who still have normal elasticity of the lower eyelids and fat that is protruding only anterocaudally. The Author will introduce a technique, which complements the limitations of these two methods mentioned above. METHODS: The author combined the transconjunctival approach and lower blepharoplasty with only the excised skin flap method. This method does not go beyond the previous methods but does apply the advantages of them. RESULTS: From March 2007 to October 2010, this new technique was performed in a total of 62 patients. Fat was removed and repositioned through transconjunctival incision. Drooped skin was excised as in the traditional blepharoplasty but only the skin flap was elevated. This prevents post-operative complications such as ectropion, sclera show, and deformation of the shape of the lower eyelids or under-resection of fat. All patients were satisfied with the post-operative appearance. CONCLUSION: The author was able to get satisfactory results while avoiding complications of traditional transcutaneous technique with this combined technique of the transconjunctival approach and the lower blepharoplasty method of skin flaps only.

Reconstruction of Injured Muscle Roll of Lower Eyelid with Alloderm(r)

The periorbital region including upper and lower eyelids is a decisive area for attractive appearance. Therefore, the blepharoplasty is one of the most frequent facial plastic surgeries performed today. In the lower eyelids region, the orbicularis oculi muscle roll gives young, charming and cute impression in general. However, in the process of lower blepharoplasty, the muscle roll can be often injured or damaged by a surgeon. In this case, the patients can complain about the loss of muscle roll and unnaturalness, Yet, the literature for reconstruction of injured muscle roll can be hardly found. By this point, we would like to introduce the methods and results of using Alloderm(R) in reconstruction of orbicularis oculi muscle roll damaged after lower blepharoplasty. From June, 2000, to May, 2002, we had reconstructed orbicularis oculi muscle roll of lower eyelids by implanting rolled Alloderm(R) in subcutaneous tunnel for 10 patients. It satisfied the patients and the revision was not performed. The reconstruction of injured muscle roll with Alloderm(r) after lower blepharoplasty is not only a simple procedure but also provides satisfactory.
