Lower lateral strut grafts mid vault stair step fashion
Lower lateral strut grafts mid vault stair step fashion
In this chapter we demonstrated both methods:with and without repositioning · For a soft and mobile tip when performing L-strut reconstruction, the costal cartilage graft for columellar strut supporting the caudal end of bilateral extended spreader graft can be placed in a more cephalic position without contacting the medial crura of lower lateral cartilages, while the columellar strut and derotation grafts using conchal · The stair-step technique, defined by Boccieri and Raimondi, is an effective repositioning technique for the repair of this deformity. The lateral crural strut graft is one of the most commonly utilized techniques for correcting LLC malposition, strengthening lateral crural support, and increasing tip projection (Figure 1, panel A),8 To perform the lateral crural strut graft, cartilage graft is fashioned into segments of mm in length and mm in widthThe graft The stair-step technique, defined by Boccieri and Raimondi, is an effective repositioning technique for the repair of this deformity. The strengthened stair-step technique, a combination of· Abstract. The strengthened stair-step technique, a combination of the Treatment includes repositioning of the lateral crus of the lower lateral cartilages with lateral crural strut graft. Cephalic positioning of the lower lateral cartilage is a very common anatomical variations and have unpleasant appearance for very patients.

The characteristics of CMLLC include long alar creases, a boxy and ball-shaped nasal tip, parenthesis tip deformity and external valvular incompetence. The gold standard for correcting CMLLC is the |

The strengthened stair-step technique, a combination ofThe lateral legs of the tripod are reconstructed in a fashion similar to that used when the domes are present. The only difference is that instead of suturing the medial end of the autogenous cartilage strip graft to the undersurface of the dome, the surgeon sutures the graft to the tip of the columellar strut | · Spreader grafts provide support of the middle vault and widen the internal nasal valve, the narrowest portion of the nasal airway which contributes approximately half of the total airway resistance. Spreader grafts are frequently indicated in functional rhinoplasty and in revision rhinoplasty when middle vault collapse is encounteredExternal nasal valve dilator strips often provide temporary relief by increasing the size of the nasal valve area and decreasing congestive symptoms. However, these strips can be cosmetically |
| · The vast majority of mid-vault surgeries consist of hump reduction and osteotomy. The frequency of hump nose reduction has been increasing among Asian patients, for whom the operation varies significantly relative to Caucasian patients. In Caucasian patients, the hump nose is characterized by excessive height of the dorsum on a long nose | · Midvault restoration is essential in maintaining a functional nose and optimizing dorsal esthetic lines after rhinoplasty. The standard method for stabilizing the middle vault is spreader graft placementThis is a critical step in patients with large dorsal humps, short nasal bones, or thin upper lateral cartilages (ULC) |
The lateral crura can also be incised via cephalic trimming · The Toriumi method is useful for collapse of external valve secondary to deficiencies of the lower lateral cartilage that lead to collapse. The Toriumi method is not appropriate for absolute narrowing of the piriform aperture or for cases of significant scarring of the valve; however, conchal grafts to the nasal floor or a Z-plasty to release · According to Toriumi (), once the lateral crus of the lower lateral cartilages is free, the next step would be to use the LCSG to help stabilize the dissected lateral crura and reposition them in a new prepared placeThe medial border of the the graft should be beveled at a° angle and fixed just short of the domus with its cephalic · Lateral crural repositioning refers to a technique in which the lower lateral cartilages are released from their lateral piriform attachments, tailored to a specific length and width, and then supported with lateral crural strut grafts repositioned in a favorable orientation.

The stair-step columella (skin) incision is initially closed with one deep layer The LLC cartilage graft on each side is on layed over the native LLC and secured (laminated) with suture. The graft will stabilize the external nasal valve and the medial crus are joined (by suture) in front of the strut graft to limit widening of the columella.
