ABSTRACT
Prosthodontic decision and management should be considered the patient’s aesthetic need for anterior teeth in maxillary edentulism. This case report describes 10-year clinical outcome of a maxillary edentulous patient was rehabilitated by means of an implant-supported fixed dental prosthesis (ISFDP) for the anterior region and a distal-extension removable partial denture (RPD) for the posterior region. The ISFDP was designed to splint 4 endosseous implants as one unit and engaged by the RPD. The edentulous mandible was restored by means of an implant-supported overdenture. Over the course, no major adverse event occurred other than wear, discoloration, and breakage of resin veneers and artificial teeth.
ABSTRACT
Based on a thorough understanding of facial structure around the superficial musculoaponeurotic system (SMAS), some types of sub-SMAS techniques have emerged to allow more harmonious rejuvenation procedures in the lower face and midface. These techniques are the Hamra composite facelift, the Stuzin extended SMAS technique, the Barton high SMAS technique, and the Ramirez subperiosteal facelift, each of which involves a specific dissection plane and is informed by distinct rationales with reasonable support. Each patient presents a unique facial structure and undergoes an individual rate of aging. The facial structures of East Asian faces, in particular, differ from those of Western faces. While emphasizing that the theory of structural mid-cheek anatomy is an essential part of facial rejuvenation, we would like to discuss the advantages and disadvantages of various sub-SMAS facelift techniques and to propose the most suitable techniques for a variety of individual faces.

BACKGROUND: The costal cartilage allows for versatile and stable cartilage supply for rhi-noplasty but disadvantages remain; to minimize these, the 10th costal cartilage was used. We present our experience with the use of the 10th costal cartilage as autologous graft material for rhinoplasty. METHODS: Sixty-four patients whose 10th costal cartilage had been used for correction of severe caudal nasal deviation, secondary cleft lip nasal deformity, and secondary rhi-noplasty with difficulty using the septal and auricular cartilages were enrolled in this study from November 2008 to December 2012. To evaluate the efficacy and safety of this method in rhinoplasty, donor-site morbidity, scarring, and postoperative results, including availability of graft material and complications, were assessed. RESULTS: The mean time for cartilage harvesting was 18 minutes, and the mean length of the harvested cartilage was 2.4 cm. The harvested cartilage was used for columellar struts and tip onlay grafts. The natural curvature of the 10th costal cartilage was used, depending on the purpose of the strut. It could be applied without carving in 38 cases (59%). Although revision was performed in three patients, there were no graft-related complications. CONCLUSIONS: The 10th costal cartilage can be harvested safely and quickly, and its han-dling procedure is simple. As such, it is a good option as an autologous graft for rhinoplasty.

BACKGROUND: This study aimed at overcoming the disadvantages of septal extension grafts and keeping the nasal tip as natural as possible by using different forms of the graft and additional supporting methods depending on the case. METHODS: Among 458 patients who received a septal extension graft from March 2008 to September 2011, 107 patients were selected who underwent at least a 6-month follow-up. Patients were categorized according to the primary objective of the operation; an upturned tip correction or tip lengthening, tip lengthening with tip projection, or retracted columella correction. Each group of patients received a different type of septal extension graft out of 3 different types of grafts based on the purpose of the operation. The evaluation of the results was made from by comparing preoperative and postoperative photographs of the tip angle, projection, and nasolabial angle. RESULTS: The average tip angle for the patients in the upturned tip correction group was reduced to 98.3 from 124.9 degrees. For the patients in the tip lengthening with tip projection group, the average tip angle was reduced to 96.8 from 122.4 degrees and the average tip projection was increased to 27.5 from 23.2 mm. The average nasolabial angle for the patients in the retracted columella correction group was increased to 94.6 from 74.8 degrees. CONCLUSIONS: Sufficient nasal tip lengthening and projection could be achieved by applying a septal extension graft using the graft best suited for the group of patients categorized by surgical objective.

We should better not confuse "short nose" with "the nose that the tip of it turned upward regardless of its length". If we simply diagnose "the nose that the tip of it turned upward" as "short nose", we might have the risk of focusing on lengthening the whole nose instead of correcting the angle of the tip of the nose. We, therefore, started to call "the nose that the tip of it turned upward" differently from "short nose" in the cases of Asian patients who have relatively short and small noses. We then decided to classify "the nose that the tip of it turned upward" as "upturned nose". And, in revision cases, we have to be careful about changes of anatomical structures, and the usage of the amount of shared cartilages, we have to be fully aware of various operation procedures to correct upturned nose. Furthermore, we have to consider many other different ways of corrections that possibly need various types of grafts and suture techniques combined or modified from the usual procedures. We achieved satisfactory results by using this new paradigm of "upturned nose" and concepts of procedures to have the better result of reforming the "short nose".
