Asian noses are mainly characterized by a low nasal dorsum, a short nose and an underprojected nasal tip due to underdeveloped (short and weak) alar cartilages. The goals of the surgery are to increase the tip projection, elongate the nose and augment the dorsum. In Asian noses the structural approach helps strengthen the weak cartilages and add definition to the nasal tip. There are various methods to increase tip projection and definition. Columellar strut, caudal septal extension graft, tip grafts and lateral crural grafts in order to elongate the upper legs of the nasal tip tripod can be used...

Multiple techniques have been described for dorsal nasal augmentation in rhinoplasty. In this article, we review common surgical techniques for raising the dorsum or eliminating dorsal irregularities, by highlighting inherent advantages and disadvantages of each method. Within the past few years, the use of diced cartilage grafts has become the workhorse in this field of interest. To overcome drawbacks of methods based on diced cartilage, we present a new concept for autologous augmentation, using regenerative medicine protocols...

Cyanoacrylate adhesives can make the placement of spreader grafts in open septorhinoplasty technically easier, but its use is off-label beneath the skin. There is a theoretical risk of toxicity from cyanoacrylate breakdown products, but this risk has not been thoroughly studied in rhinoplasty. The objective was to evaluate the effects of subcutaneous cyanoacrylate use during spreader graft placement in rhinoplasty in a retrospective review of open septorhinoplasties in which 2-octyl cyanoacrylate was used to aid placement of spreader grafts...

Costal cartilage grafting is increasing in popularity with increased demand for augmentation rhinoplasty and increased need for grafting material for structure rhinoplasty techniques. Use of costal cartilage for dorsal grafting is both art and science. The art is demonstrated in the act of carving a dorsal graft that will reflect the actual contour of the nasal dorsum. The science is linked to the methodology of how the grafts are contoured to match the patient's desires and how the graft is fixed to the bony dorsum to minimize the risk of warping and displacement...

Dorsal augmentation grafts are used to reconstruct and raise the nasal dorsum in patients with dorsal saddling due to trauma, infection, or previous nasal surgery, as well as in patients with a narrow, congenitally low, and/or wide dorsum. Alloplastic implants and various biomaterials are available for grafting, each with advantages and disadvantages. Although autologous septal cartilage is a preferable and often convenient source of cartilage, it is frequently not sufficient for large volume dorsal augmentation, nor is it available in patients who have had septoplasty, infection, previous rhinoplasty with grafting, or significant trauma...

The nasal midvault is an important consideration in rhinoplasty. This region is defined by the attachment of the upper lateral cartilages (ULCs) to the nasal bones superiorly and the cartilaginous septum medially. Inadequate management of the nasal midvault can have negative functional and aesthetic ramifications. Indications for midvault reconstruction in primary rhinoplasty include a narrow midvault, dorsal hump resection, a deviated midvault, and an asymmetric midvault, with an additional relative indication of zone 1 lateral wall insufficiency (LWI), defined as dynamic collapse of a weakened lateral nasal wall at the level of the ULC...

BACKGROUND: Secondary rhinoplasty often involves the addition of autogenous graft material to add volume, structure, support and to camouflage cartilage and bone grafts. A variety of fascias have been used to camouflage, wrap and give "fill" in secondary rhinoplasty. The posterior auricular fascia is a source of material ideal for such purposes, and its quantity, anatomical structure and ease of harvest with minimal donor site morbidity make it a versatile and attractive autogenous graft...

BACKGROUND: Regarding septal fixation in nasal tip plasty, the nasal tip tripod theory may require modification. We performed three-dimensional (3D) photogrammetric analysis of the "Skiff graft," which is a quadripod method involving folded conchal cartilages fixated on the caudal septal angle, paired lateral crura reinforced by a derotational conchal cartilage graft, and conjoined medial crus on the columella base. We assessed the efficacy of the Skiff graft in maintaining tip projection and preventing cephalic rotation of the nasal tip...

INTRODUCTION: Surgical manipulation of the lower lateral cartilages of nasal tip could cause subtle but significant responses to the manipulation. The suture-techniques almost always offer a reliable and dramatic method of tip reshaping without a need to break or interrupt the alar rim strip or even adding tip graft. AIM: The aim of this study was to describe and assess outcomes of a new suture technique in rhinoplasty by using cephalic dome septal rotation suture for better tip definition...

The objective of the present study was to investigate the functional consequences of aesthetic rhinoplasty. The authors compared the results of corrective surgery depending on the surgical approach, the extent of the intervention, and the operative techniques employed based on large enough set of clinical observations obtained during the treatment of 253 patients. It was shown that the post-rhinoplastic difficulties in nasal breathing experienced by some patients occurred significantly more frequently after the use of the «endonasal» surgical approach than following «open» rhinoplasty (75% vs 68%)...

The nasal valve area is the functional area that allows airflow regulation. It could be divided in an internal area and an external one, basing on the anatomical landmarks. Many conditions can damage these areas with a consequently nasal obstruction, more often in particular extended rhinoplasty and sequels of facial trauma. To restore this area many techniques were advocated during the last decades.In this article the authors investigate on valve areas deficiency in sequel of rhinoplasty proposing a structural approach through alar batten grafts to correct internal-external nasal valves collapse...

BACKGROUND: In Asian rhinoplasty, many autogenous cartilage grafts are required for correction of the nasal tip and columella, but the amount has limitations. A modified direct-type septal extension graft, in continuity with the entire caudal border of the septal cartilage with an edge-to-edge coaptation, can effectively and concomitantly correct the nasal tip and columella deformities using a limited amount of septal cartilage graft. The purpose of this study was to evaluate long-term cosmetic outcomes and stability from the modified direct extension grafts...
