vent the creation of an aesthetically pleasing nasalshape and contour.

The importance of lower lateral crural shapeand strength is best seen in noses that have pre-viously been operated on. Secondary rhinoplastypatients commonly demonstrate a weakened exter-nal valve from excessive cephalic cartilage resection,destructive cartilage scoring or crushing techniques,or tip suturing techniques that are performedwithout establishing alar support.1–3,7–10,14 Once ex-ternal valve insufficiency and alar retraction arepresent, the treatment becomes more complexand often mandates the use of lateral crural strutgrafts15 and/or other cartilage grafts in patientswho are commonly cartilage-depleted. Lower lat-eral crural strut grafts,15 alar contour grafts,16 andalar batten grafts17,18 have all been described forrestoring alar arch shape and integrity while pro-viding the ability to create an aesthetic tip complexand alar contours.

Occasionally, an adequate lower lateral cruralremnant is present or no cephalic resection has beenperformed, which may obviate the need for support-ive grafting techniques. In 1997, McCollough andFedok19 described a unique modification to alargrafting techniques to correct lower lateral cruraldeformities that involved completely excising acephalic strip of the concave lower lateral cruraduring closed rhinoplasty and turning it over ontothe concave native lower lateral crura, therebynegating the deformity. This bilaminate construct,when secured with sutures, straightened the con-cave lower lateral crura while providing addedstrength.19 The technique also obviated the needfor other graft techniques or additional cartilagedonor sites, while utilizing cartilage that wouldhave otherwise been discarded.

We have modified McCollough’s lower lateralcrural turnover graft19 by creating a vascularizedlower lateral crural flap that is connected by intactanterior perichondrium, turned over, and suturedto the remaining caudal lower lateral crural seg-ment. This technique has been applied to thecorrection of lower lateral concavities, strength-ening the external valve, and prevention of lowerlateral crural weakness from tip suturing effects.The indications, contraindications, and long-termresults of this technique are delineated through areview of primary, secondary, and tertiary rhino-plasties.

ANATOMIC CONSIDERATIONSThe lower lateral crura demonstrate variations

in thickness, shape, width, length, and degree/lo-cation of concavities and convexities.4–6,10 Daniel4

points out the transition from the dome (middlecrura) to the lateral crus has an angular depres-sion that is termed the domal junction (60 to 80degrees). This is created by the convexity of thedome meeting the concavity of the lateral crusat the lateral genu. The lateral crura becomeconvex again as they join the accessory cartilagecomplex.4 Neu6 describes the types of alar car-tilage concavities based on their location: lateralcrus, lateral dome, and medial dome. These an-atomical differences account for the aestheticappearance of the alar arch and domes.6,20 Mul-tiple authors have all described techniques thatcreate an aesthetic alar contour as well as im-prove alar arch strength, position, and externalvalve function.15,16,21,22

The ideal alar basal view should be an equi-lateral triangle with slight alar flaring toward thealar base.16 Alar concavities and convexities onbasilar view can be identified relative to the posi-tion of the lateral alar outline. A medial alar con-tour line relative to the lateral limbs of an equi-lateral triangle suggests alar concavity, in contrastto lateral deviation from this line, which suggestsalar convexity (Fig. 1).21

The position, degree of concavity, and in-tegrity of the lower lateral crura directly affectalar arch strength and external nasal valvecompetence.5,8 –10 When the lower lateral cruraare oriented vertically, the alar arch is at a me-chanical disadvantage and is not well supported.This leads to primary external valve insufficiency

Secondary external valve incompetence can alsoresult from untreated preexisting lower lateralcrural malposition, from prior excessive cephalictrim, or from iatrogenic deformational forcescaused by numerous tip suturing, weakening,and/or scoring techniques.7–13

PATIENTS AND METHODSWe performed a retrospective case review of

consecutive primary (n � 21), secondary (n � 2),and tertiary (n � 1) rhinoplasties in which thelower lateral crural turnover flap was used with orwithout other grafting techniques. The indica-tions, contraindications, and long-term results ofthis technique were defined based on preopera-tive, intraoperative, and postoperative patientanalysis. Complications and further refinementsof this technique will be presented.

tibular skin is then infiltrated and hydro-dissectedwith 1 cc of 1% xylocaine with epinephrine tofacilitate dissection. A 5- to-7 mm total width oflower lateral cartilage is turned over depending onthe inherent total width, thickness, and deformityof the cartilage. The average width of the nativelower lateral cartilage should therefore be greaterthan 1.2 cm to accommodate a lower lateral cruralturnover flap to preserve at least a 6-mm caudalrim strip. The vestibular skin is undermined offthe entire cephalic border of the cartilage untilthe markings are visualized on the undersurfaceof the cartilage. At this point, 2-mm full-thicknessincisions are made in the medial and lateral mar-gins of the cartilage, and the remainder of theundersurface is scored with a no. 15 blade scalpel.The integrity of the anterior surface of the carti-lage and its perichondrium is maintained.

The cephalic cartilage flap is then turned overonto the remnant caudal cartilage, ensuring ad-equate release and mobility of the flaps. Occa-sionally, lateral and/or medial back-cuts are re-quired to allow for tension-free turnover. By usingtwo Adson Brown forceps to stabilize and flattenthe cartilage, the turnover flaps are secured toeach other with a series of three to four caudallybased simple 5-0 Vicryl sutures. Care is taken toavoid incorporating the vestibular skin in the car-tilaginous reapproximation (Fig. 2).

The flaps are evaluated for adequate correc-tion of the anatomic defect. The two-layer lowerlateral cartilages should now appear flat with agentle cephalic orientation. The flaps are evalu-ated for adequate correction of the anatomic de-fect and for improved alar support. This tech-nique is employed before performing tip suturingand/or other alar rim grafting techniques. De-pending on the tip shape desired, the medial ex-tent of the turnover can be extended medial to thelateral genu to serve as an augmentative graft inthe dome regions. The flap can be strengthenedand augmented by incorporating an alar battengraft into the construct.

RESULTSThe lower lateral cartilage flap was performed

during 21 primary rhinoplasties, two secondaryrhinoplasties, and one tertiary rhinoplasty. Theindications for the lower lateral crural turnoverflap are listed in Table 1. The open approach wasutilized in all cases. Primary rhinoplasty patientsusually have adequate available lower lateral crura;therefore, this technique was more commonlyused in primary cases. In three revisionary rhino-plasties (two secondary and one tertiary), there

was a sufficient lower lateral crural remnant thatwas used for the flap. In cases of moderate to severealar contour deformity or external valve incompe-tence, other techniques, such as lateral crural strutgrafts, alar spreader grafts, alar batten, and/or alarcontour grafts, were also used. These additionaltechniques did not obviate the need for nor com-promise the effect of the lower lateral crural turn-over flap; they only augmented the utility of the graftin terms of added additional support to the alar rimand alar soft triangles. No cases of alar notching orexternal valve collapse were seen postoperatively.The long-term results of the grafts were excellent,with all patients showing contour retention and last-ing results in their 6-month and 1-year postoperativephotographs. The revision rate in this study was 4.2percent, with only one patient presenting with apostoperative iatrogenic unilateral asymmetry. Onrevision of the turnover flap, it appeared that themedial corner of the flap had elevated, creating avisible and palpable deformity (Fig. 3). This under-scores the importance of incising the full thicknessof the cartilage at the medial and lateral margins ofthe lower lateral crural turnover flap and the needto completely score the entire length on the poste-rior lower lateral crura, ensuring that there is min-imal to no tension on the corners as the flap is beingturned over and sutured down. Buckling that is seenat the corners should be corrected by excision, ad-ditional suture placement, or further scoring. It isparamount to meticulously tailor the grafts at theedges, especially in patients with a thin skin enve-lope, as otherwise visible deformities can result.

A 29-year-old woman presented with complaints of a slightdorsal hump, a wide nasal dorsum, a bulbous, deviated tip, andincreased infratip lobular show. The lateral view confirms theslight dorsal hump with a low radix, supratip fullness, decreasedtip rotation, and decreased columellar-labial angle. The basalview confirms the rounded, bulbous tip with left-sided devia-tion, and bilateral alar collapse with widened alar bases andconcave lower lateral cartilages.

The operative plan was as follows: open rhinoplasty via atranscolumellar incision with bilateral infracartilaginous exten-sions, 3-mm component dorsal reduction, septal harvest leavinga 10-mm dorsal and caudal L-strut, septal cartilage radix graft,2-mm dorsal augmentation with multilayered septal cartilage

grafts, bilateral lower lateral crural turnover flaps, columellarstrut, tip refinement with interdomal and transdomal sutures,low to low intranasal osteotomies, and 4-mm alar base resections(Figs. 4 and 5).

At 12 months after the procedure, the patient had a straightdorsum, unification and correction of her tip asymmetry, andan improved nasal base–to–tip relationship. The lateral viewconfirms a straight dorsal profile with a slight supratip break,a nasolabial angle of 95 degrees, an improved alar-columellarrelationship, and normal tip projection. The basal view showscorrection and refinement of the tip asymmetry and restorationof the columellar infratip lobular relationship (Fig. 6). Thelower lateral turnover flaps in this patient served to directlycorrect the collapsed external vault and improve alar contour.

The lateral view confirmsthe slight dorsal hump, supratip fullness, decreased tip projec-tion, and a columellar-labial angle of 100 degrees. The basalview confirms the asymmetric tip with left-sided alar collapse.The right lower lateral cartilage is convex and the left is concave.There is left-sided deflection of her caudal septum.

caudal septal resection with medial crural set-back sutures (5-0polydioxanone suture), left lower lateral crural turnover flap,right cephalic lower lateral cartilage resection leaving a 6-mmlower lateral crural width, columellar strut, tip refinement withinterdomal and transdomal sutures (5-0 polydioxanone su-ture), placement of bilateral alar contour grafts, and externallateral percutaneous osteotomies (Figs. 8 and 9).

At 12 months after the procedure, the patient had a straightdorsum and unification of her tip with correction of her asym-metry (Fig. 10). The lateral view confirms a straight dorsalprofile with a slight supratip break, a nasolabial angle of 95degrees, an improved alar-columellar relationship, and normaltip projection. The basal view shows correction of the tip asym-metry and restoration of the columellar infratip lobular rela-tionship. The left-sided lower lateral turnover flaps in this pa-

tient served to directly correct the left-sided collapsed externalvault to achieve symmetry with the contralateral side. The alarcontour grafts were used prophylactically to prevent postoper-ative alar retraction.

DISCUSSIONAn aesthetic nasal tip and alar arch possess a

gentle transition in contour and shape betweenthe two. Excessive concavity in the lower lateralcrura detracts from creation of the ideal nasal tipand alar arch shape. More importantly, lower lat-eral crural concavities can lead to external nasalvalve collapse, alar retraction, and/or a pinched

nasal tip. Alar retraction and incompetence canalso result from weakened and/or malposi-tioned lower lateral crura. Collapse occurs at theanterior and midportion of the rim, as theseareas are directly supported by the lateral crus.Lower lateral crural malposition can be cor-rected by lateral crural strut grafting15 or battengrafting,17,18 with or without lower lateral cruralrepositioning and/or transection at the acces-sory chain level.9,15,17,18

McCollough and Fedok19 described an inge-nious, yet simple, technique to correct lower lat-eral crural concavities using the “lateral cruralturnover graft” in a closed approach via a cartilagedelivery technique. The impetus for their techniquecame from the prevailing destructive techniquesthat were more commonly applied, includingmorselization, cartilage transection, and scoring.

Their technique has the advantage of augmentingthe lower lateral crura with native, adjacent tissuethat would otherwise be removed as a cephaliccartilage remnant, thereby obviating the need forharvest from a different cartilage site. Our intriguewith this concept led to its adaptation and mod-ification for use in open rhinoplasty, which in-volves scoring and turning over of the cephalicportion of the lower lateral crura onto the remain-ing caudal cartilage as a vascularized flap that re-mains attached by anterior perichondrium. Thisconcept of utilizing “spare parts” in rhinoplastyhas recently been applied by Byrd et al.23 andGruber et al.24 through use of the “autospeaderflap” for internal nasal valve insufficiency and/ora narrow midvault.

Advantages of the lower lateral crural turnoverflap technique include utilization of adjacent ex-

Page 9: Lower Lateral Crural Turnover Flap in Open Rhinoplasty...flaps have had long-lasting results ( 1 year) after open rhinoplasty. Conclusions: The lower lateral crural turnover flap is

pendable cartilage (with avoidance of other graftsites) and preservation of inherent vascularity. Thebiomechanical benefit to this technique stemsfrom the fact that the concave cephalic segment istransposed over the caudal segment and, in doingso, creates a convex-to-concave interposition of op-posing intrinsic forces, which serves to strengthenand support the remaining lower lateral cruralsegment and support the alar arch. This techniquecan be used to correct both unilateral and bilateraldeformities.

Suturing techniques to correct lower lateralcrural concavities have also been described butmay not be as strong or predictable as the cre-ation of this bilaminate lower lateral crural

construct.1,6,24 –27 Use of lower lateral crural mat-tress sutures to straighten lower lateral cartilageconcavities and/or lateral crural spanning su-ture to establish favorable lateral crural positionand shape can produce undesirable dynamic ef-fects on lower lateral crural position and tip po-sition/shape without providing sufficient biome-chanical alar support. Secondary concavities in thelower lateral crural can be produced by tip sutur-ing forces, most notably at the lower lateral crural/accessory cartilage junction.1–3,13,14 Kridel et al.13

describe the “lateral crural steal” phenomenon,which is a concavity and weakness produced in thelower lateral crural as tip suturing is employed.Further weakness in alar support is produced

Page 10: Lower Lateral Crural Turnover Flap in Open Rhinoplasty...flaps have had long-lasting results ( 1 year) after open rhinoplasty. Conclusions: The lower lateral crural turnover flap is

when tip suturing is combined with cephalic lowerlateral crural resection despite maintaining an ad-equate caudal width. This may be more prevalentwhen the native lower lateral crura are concave.Therefore, reinforcing the cartilage of the lateralcrura is critical when employed concomitantlywith tip suturing techniques in the setting of mal-positioned, weak, and/or concave lower lateralcrural to prevent postoperative external valve dys-function.

This technique may also be applied to theethnic nose to correct intrinsic or iatrogenicdeformities of the lower lateral crura. The alarcartilages in the ethnic nose are commonlywider than those in the Caucasian nose andpossess variable strengths, which make the lowerlateral crural turnover flap an attractive tech-

nique in these populations.28 –31 The increasedwidth of the native lower lateral cartilage inthese cases allows for more frequent opportu-nities to use this graft while maintaining alarstability through preservation of an adequatecaudal rim strip. Furthermore, iatrogenic lowerlateral crural deformation caused by nasal tipelevation and alar base narrowing maneuvers(which are commonly performed in these pop-ulations) can be prevented or treated by theaugmentation of cartilaginous strength pro-vided by the lower lateral crural turnover flap.

While the lower lateral crural turnover flapcan be performed in secondary rhinoplasty, as-surance that there is adequate cephalic lowerlateral crural cartilage is mandatory. Secondaryrhinoplasty may require the use of other graft-

ing techniques from local or distant cartilageharvest sites. Common grafting techniques includelower lateral crural struts,15 batten grafts,17,18 alarcontour grafts,16 alar rim grafts,25 alar spreadergrafts,21 and other turnover grafts.9,25 Comple-mentary graft techniques can also be employedwith lower lateral crural turnover flaps. Com-monly, alar contour grafts are combined withthe lower lateral crural turnover flap to supportand shape the alar rim and soft triangle. Smallamounts of additional cartilage are needed forthese grafts, making them a simple addition ifneeded. Alar batten grafts can also be insertedin between or anterior to the lower lateral cruralturnover flaps. These grafts may be applied tostrengthen and reinforce the thin, weak lowerlateral crural cartilage even in the setting ofturnover flaps.

CONCLUSIONSThe lower lateral crural turnover flap is a use-

ful and reproducible technique in open rhino-plasty with enduring results. The use of adjacentcartilage provides a local source of viable tissue tocorrect and support the lower lateral crura in bothprimary and revision rhinoplasty.
