Fresh Frozen Rib Cartilage Grafts in Revision Rhinoplasty: A 9-Year Experience.

Background: Revision rhinoplasty is undoubtedly one of the most challenging procedures in facial plastic surgery. The complexity is compounded when there is a paucity of native septal cartilage to perform the required framework reconstruction. Harvest of autologous costal cartilage can result in increased operative times and possible secondary-site complications such as contour irregularity, poor scarring, and even pneumothorax.

Systematic Surgical Approach to Alar Base Surgery in Rhinoplasty.

In an era with smartphone photography and social media (specifically, "selfies"), basal view aesthetics is becoming increasingly important. Achieving balance between the nasal base and the remainder of the nose and face while preserving or restoring external valve function are essential to a successful rhinoplasty. Without a systematic approach to the nasal base, it is more difficult to achieve an ideal outcome from both aesthetic and functional standpoints.

Rhinoplasty Refinements: Addressing the Deviated, Overprojected Nose.

Deprojection of an overprojected nose and correction of an infralobular deformity are very challenging for rhinoplasty surgeons because a systematic approach is needed to correct these problems. A deviated nose with a dorsal hump is a common deformity that is best treated using septal reconstruction and the component dorsal hump reduction technique using an open rhinoplasty approach. This article and its videos show how to correct a deviated nose with overprojection and a dorsal hump deformity.

Rhinoplasty Refinements: Revision Rhinoplasty Using Fresh Frozen Costal Cartilage Allograft.

A crooked nose is challenging for a surgeon and needs to be treated using a systematic approach. Correction of nasal deformities such as a retracted columella in a revision rhinoplasty may need additional cartilage to correct the framework. Fresh frozen cartilage graft has been used as an extended spreader graft and a columellar strut graft to correct this problem.

With a growing massive weight loss population, upper arm contouring continues to rise in popularity. Refinements in technique, such as modification of skin excision patterns and the adjunct use of liposuction, have allowed for safe and reproducible results. This article helps to understand the evolution of upper arm contouring and provides an update on the limited-incision medial brachioplasty.

Male Rhinoplasty: Update.

Male rhinoplasty is unique in that it requires precise preoperative planning to achieve a successful result. Better communication and clarity are paramount with male rhinoplasty patients because the patients may be less attentive. It is important for the surgeon to screen the patients for any psychosocial disorders.

Rhinoplasty Refinements: Addressing the Pollybeak Deformity.

Pollybeak deformity represents one of the most common complications of rhinoplasty that require revision rhinoplasty for correction. This article helps to understand the basis behind the deformity, which helps us to prevent and to treat this deformity. This article and video also reiterate that systematic facial analysis is important to look for imperfections and asymmetries in other parts of the face and show how a chin augmentation is performed to correct microgenia.

Preventing Lateral Canthal Malposition in Modern Blepharoplasty.

Current goals in lower eyelid blepharoplasty include blending the lower eyelid-cheek junction, which is highlighted in the authors' six-step lower lid blepharoplasty technique. One major question in lower lid blepharoplasty is how to prevent lower lid malposition and ectropion, because these are untoward outcomes after an aesthetic procedure. In the authors' technique, they perform a superficial lateral retinacular canthopexy that is effective and safe and also prevents lower lid malposition or ectropion.

Chemical Peels: Role of Chemical Peels in Facial Rejuvenation Today.

The practice of chemical peeling remains an important aspect of the nonsurgical techniques available to the aesthetic surgeon when approaching skin rejuvenation. Despite past predictions of their disappearance in favor of lasers, the overall use of chemical peels by plastic surgeons continues to grow. In the past two decades, the techniques available to the clinician have evolved in safety and efficacy based on the dermatologic investigations of various individuals, including Obagi, Hetter, and Stone.

Role of Ancillary Procedures in Facial Rejuvenation.

Face-lift techniques have evolved beyond the concept of lifting and now include incorporating superficial and deep filling of facial fat compartments to address volume deflation and aging. In addition to traditional face-lift methods involving the excision and tightening of skin and the underlying soft tissues, the following ancillary procedures have become paramount in achieving an optimal result: blending the lid-cheek junction; chin augmentation; lobule augmentation; hand rejuvenation; perioral rejuvenation; chemical peels; and laser resurfacing. We presented a summary of these integral techniques.

Recognizing Racial Heterogeneity in the Latino Nose: Aesthetic Concepts for an Individualized Approach.

Background: Latinos are one of the fastest growing ethnic groups in the United States, and there is a growing demand for aesthetic rhinoplasty in these patients. The authors provide an individualized, systematic approach for evaluation and improvement of surgical outcomes in Latino patients.

Methods: A retrospective review of patients identified as Latino who underwent primary rhinoplasty and those who did not but had documented nasal photographs was performed.

Role of Fresh Frozen Cartilage in Revision Rhinoplasty.

Background: Correction of secondary nasal deformities frequently requires cartilage to build the framework of the nose. Traditionally, autologous costal cartilage has been used because of the paucity of the septal cartilage. Because of associated donor-site complications and increased operating time, irradiated allografts have been used.

Clinical Implications of Gluteal Fat Graft Migration: A Dynamic Anatomical Study.

Background: The intraoperative mortality and overall complication rate for gluteal augmentation with fat transplantation is unacceptably high. The current controversy among experts regarding safety is whether fat should be placed within the gluteus muscle or limited to only the subcutaneous space. The purpose of the present study was to test the hypothesis that under certain pressures, fat injected within the gluteal muscle can actually migrate out of the muscle and into a deeper plane containing critical neurovascular structures, by means of the process of deep intramuscular migration.

Proximalization of the Vascularized Toe Joint in Finger Proximal Interphalangeal Joint Reconstruction: A Technique to Derive Optimal Flexion From a Joint With Expected Limited Motion.

When used to reconstruct a finger proximal interphalangeal joint, a free toe interphalangeal joint, without modification, cannot meet the motion demands of the finger to allow palm touchdown. This limitation is the direct result of the toe interphalangeal joint having an intrinsic arc of motion that delivers less flexion than that of a normal functioning finger proximal interphalangeal joint. By modifying the inset of the transferred joint to an extra-anatomical more proximal position, this limitation can be overcome.
