the paramedian forehead flap was found to be highly versatile in its design and&#44; as a result&#44; covered a wide range of possible indications&#46; The flap can be adapted to proximal and distal nasal defects by simply varying the length of the pedicle&#46;

This is a flap with a thick axial pedicle that guarantees the viability of the donor skin and can even enhance nutrient delivery to other tissues &#40;chondromucosal and mucocutaneous grafts&#41; that may be used in combination with a paramedian forehead flap for the reconstruction of deep nasal defects&#46;<a class="elsevierStyleCrossRefs" href="#bib0150"><span class="elsevierStyleSup">8&#8211;11</span></a> Furthermore&#44;

are the main measures used to prevent vascular suffering of the flap&#46; In our series only 1 patient presented extensive necrosis of the whole flap&#59; that patient was a heavy smoker&#46; In other patients who presented necrosis&#44; it was superficial and affected only limited areas&#59; those cases may have been related to the use of distal flaps in patients with diseases that increase vascular risk&#46; All our cases with necrosis resolved with conservative debridement&#44; and the final cosmetic and functional results were not affected&#46;</p><p id="par0135" class="elsevierStylePara elsevierViewall">A final advantage that should be noted for this type of flap is the good cosmetic and functional result that can be achieved in the majority of cases&#46; This is due in part to the use of skin from the forehead to create the flap&#59; the texture&#44; color&#44; and flexibility of this skin are very similar to the skin of the external nose&#46;</p><p id="par0140" class="elsevierStylePara elsevierViewall">The paramedian forehead flap does have some possible disadvantages that the surgeon must be aware of&#46; The main disadvantage is that it is a 2-stage procedure&#44; usually with an interval of 3 weeks between the operations&#46; Although the second stage &#40;in which the vascular pedicle is divided&#41; is a simple&#44; low risk procedure that can be performed under local anesthesia&#44; the fact that the overall surgical procedure is prolonged can considerably reduce the patient&#39;s quality of life&#46; A reduction in the interval between operations<a class="elsevierStyleCrossRef" href="#bib0190"><span class="elsevierStyleSup">16</span></a> and tunneling the vascular pedicle beneath the healthy skin<a class="elsevierStyleCrossRefs" href="#bib0195"><span class="elsevierStyleSup">17&#44;18</span></a> of the dorsum of the nose have been described by various authors as options to reduce this disadvantage without affecting the cosmetic result&#46; However&#44; tunneling the vascular pedicle is a complex surgical technique&#44; particularly in distal defects&#44; when it can often provoke skin thickening over the whole of the dorsum of the nose&#46;</p><p id="par0145" class="elsevierStylePara elsevierViewall">Further disadvantages include the scar created on the forehead and the large amount of healthy forehead skin that is lost when the pedicle is divided&#46; However&#44; despite this considerable loss of forehead tissue&#44; the defect can often be closed directly or by the advancement of adjacent tissues&#44; with no major cosmetic repercussions&#46;<a class="elsevierStyleCrossRef" href="#bib0120"><span class="elsevierStyleSup">2</span></a></p><p id="par0150" class="elsevierStylePara elsevierViewall">Finally&#44; the paramedian forehead flap can give rise to specific sequelae due to its particular anatomic features&#59; important sequelae are the transposition of forehead hair &#40;<a class="elsevierStyleCrossRef" href="#fig0020">Figure 4</a>&#41; and excessive flap thickness &#40;<a class="elsevierStyleCrossRef" href="#fig0025">Figure 5</a>&#41;&#46; The transposition of hairy skin from the scalp to the area of the nose occurs in patients with a low hairline&#59; this can be resolved later by electrolysis or laser treatment of the hair follicles&#46; Excessive flap thickness is the most common sequela&#46; The main preventive measure is surgical thinning of the flap&#46; Although this can be performed early &#40;during dissection of the flap or when the pedicle is divided&#41;&#44; postponement is recommended in patients with vascular risk factors in order to avoid compromising the viability of the donor tissue&#46; Corticosteroid infiltration in the thickened area can also accelerate the thinning process&#46;<a class="elsevierStyleCrossRef" href="#bib0205"><span class="elsevierStyleSup">19</span></a> However&#44; excessive thickness resolves spontaneously over the first year in a large percentage of cases&#44; and many authors therefore recommend a conservative approach&#46;</p><elsevierMultimedia ident="fig0020"></elsevierMultimedia><elsevierMultimedia ident="fig0025"></elsevierMultimedia><p id="par0155" class="elsevierStylePara elsevierViewall">Our experience has revealed some clues to the optimization of flap results&#46; An appropriate design and a meticulous technique are essential to ensure the blood supply and viability of the flap&#46; The design is based on the supratrochlear artery&#44; which ascends vertically in the paramedian region &#40;2<span class="elsevierStyleHsp" style=""></span>cm from the midline&#41; over the frontalis muscle&#46; Distally&#44; its terminal branches are connected to the vessels of the subdermal plexus of the scalp&#46; However&#44; the most proximal segment of the supratrochlear artery descends between the orbicularis oculi and corrugator muscles to reach the periosteal plane&#46; Here the artery anastomoses with branches of the angular and supraorbital arteries&#46; Meticulous dissection of the flap will preserve the 3 vessels&#44; maximizing blood flow to the pedicle&#46;<a class="elsevierStyleCrossRef" href="#bib0130"><span class="elsevierStyleSup">4</span></a> Designing the flap to respect the anatomic subunits of the nose<a class="elsevierStyleCrossRefs" href="#bib0210"><span class="elsevierStyleSup">20&#44;21</span></a> allows the incisions to be concealed in the borders between these subunits&#44; thus improving the cosmetic results&#46; Finally&#44; procedures for secondary review&#44; such as dermabrasion of the skin surface&#44; can improve the cosmetic result and achieve a more homogeneous appearance<a class="elsevierStyleCrossRefs" href="#bib0215"><span class="elsevierStyleSup">21&#44;22</span></a> in those cases in which this is required&#46;</p><p id="par0160" class="elsevierStylePara elsevierViewall">The limitations of our study stem from its retrospective design and the small size of the sample&#46; Further studies are necessary to analyze the factors associated with possible complications&#44; such as measures of the subjective evaluation by the patient &#40;perception of changes in quality of life and tolerance of or satisfaction with the results&#41;&#46;</p><p id="par0165" class="elsevierStylePara elsevierViewall">In conclusion&#44; the paramedian forehead flap is a useful&#44; safe&#44; and versatile technique&#46; Its main indication is for the repair of nasal tissue defects with a diameter greater than 1&#46;5<span class="elsevierStyleHsp" style=""></span>cm&#44; which exceed the possibilities of local flaps&#44; particularly when the defects affect the full thickness of the wall &#40;skin&#44; cartilage&#44; and mucosa&#41;&#46; Optimization of results depends on the use of a careful technique and preservation of the cosmetic subunits &#40;<a class="elsevierStyleCrossRef" href="#fig0030">Figure 6</a>&#41;&#46;

the paramedian forehead flap was found to be highly versatile in its design and&#44; as a result&#44; covered a wide range of possible indications&#46; The flap can be adapted to proximal and distal nasal defects by simply varying the length of the pedicle&#46; Likewise&#44; its size can be modified to provide sufficient tissue to replace the skin of the whole of the external nose&#46;<a class="elsevierStyleCrossRefs" href="#bib0130"><span class="elsevierStyleSup">4&#44;7</span></a></p><p id="par0120" class="elsevierStylePara elsevierViewall">Another property of the paramedian forehead flap is its excellent vascularization&#46; This is a flap with a thick axial pedicle that guarantees the viability of the donor skin and can even enhance nutrient delivery to other tissues &#40;chondromucosal and mucocutaneous grafts&#41; that may be used in combination with a paramedian forehead flap for the reconstruction of deep nasal defects&#46;<a class="elsevierStyleCrossRefs" href="#bib0150"><span class="elsevierStyleSup">8&#8211;11</span></a> Furthermore&#44; its rich blood supply helps to achieve a low rate of complications&#44; even in patients with comorbid conditions&#46;<a class="elsevierStyleCrossRefs" href="#bib0130"><span class="elsevierStyleSup">4&#44;12</span></a></p><p id="par0125" class="elsevierStylePara elsevierViewall">Necrosis is the most common complication reported &#40;16&#37;&#41;&#44;<a class="elsevierStyleCrossRef" href="#bib0175"><span class="elsevierStyleSup">13</span></a> and this was also the situation in our series &#40;10&#37;&#41; &#40;<a class="elsevierStyleCrossRef" href="#fig0015">Figure 3</a>&#41;&#46; Equally&#44; because this is a flap with an open pedicle&#44; bleeding is common during the first 24<span class="elsevierStyleHsp" style=""></span>hours&#44; but tends to cease spontaneously&#46; Excessive bleeding or its persistence beyond the early postoperative period is very rare &#40;2&#46;5&#37; in our series&#41;&#46; The incidence of other postoperative complications&#44; such as infection or wound dehiscence&#44; is very low&#46;<a class="elsevierStyleCrossRef" href="#bib0175"><span class="elsevierStyleSup">13</span></a></p><elsevierMultimedia ident="fig0015"></elsevierMultimedia><p id="par0130" class="elsevierStylePara elsevierViewall">The robust blood supply of the pedicle means that&#44; if necrosis develops&#44; it is usually only superficial or partial&#46;<a class="elsevierStyleCrossRef" href="#bib0175"><span class="elsevierStyleSup">13</span></a> A number of studies have reported a relationship with certain risk factors&#44; particularly with smoking&#44;<a class="elsevierStyleCrossRefs" href="#bib0175"><span class="elsevierStyleSup">13&#44;14</span></a> cardiovascular diseases&#44; and diabetes&#44; and with technical aspects that reduce the viability of the flap &#40;a long pedicle&#44;

quitting smoking<a class="elsevierStyleCrossRef" href="#bib0180"><span class="elsevierStyleSup">14</span></a> and the use of deferred transposition techniques<a class="elsevierStyleCrossRef" href="#bib0185"><span class="elsevierStyleSup">15</span></a> &#40;incision of the perimeter of the flap in an initial operation and flap elevation 3 weeks later&#41; are the main measures used to prevent vascular suffering of the flap&#46; In our series only 1 patient presented extensive necrosis of the whole flap&#59; that patient was a heavy smoker&#46; In other patients who presented necrosis&#44; it was superficial and affected only limited areas&#59; those cases may have been related to the use of distal flaps in patients with diseases that increase vascular risk&#46; All our cases with necrosis resolved with conservative debridement&#44; and the final cosmetic and functional results were not affected&#46;</p><p id="par0135" class="elsevierStylePara elsevierViewall">A final advantage that should be noted for this type of flap is the good cosmetic and functional result that can be achieved in the majority of cases&#46; This is due in part to the use of skin from the forehead to create the flap&#59; the texture&#44; color&#44; and flexibility of this skin are very similar to the skin of the external nose&#46;</p><p id="par0140" class="elsevierStylePara elsevierViewall">The paramedian forehead flap does have some possible disadvantages that the surgeon must be aware of&#46; The main disadvantage is that it is a 2-stage procedure&#44; usually with an interval of 3 weeks between the operations&#46; Although the second stage &#40;in which the vascular pedicle is divided&#41; is a simple&#44; low risk procedure that can be performed under local anesthesia&#44; the fact that the overall surgical procedure is prolonged can considerably reduce the patient&#39;s quality of life&#46; A reduction in the interval between operations<a class="elsevierStyleCrossRef" href="#bib0190"><span class="elsevierStyleSup">16</span></a> and tunneling the vascular pedicle beneath the healthy skin<a class="elsevierStyleCrossRefs" href="#bib0195"><span class="elsevierStyleSup">17&#44;18</span></a> of the dorsum of the nose have been described by various authors as options to reduce this disadvantage without affecting the cosmetic result&#46; However&#44; tunneling the vascular pedicle is a complex surgical technique&#44; particularly in distal defects&#44; when it can often provoke skin thickening over the whole of the dorsum of the nose&#46;</p><p id="par0145" class="elsevierStylePara elsevierViewall">Further disadvantages include the scar created on the forehead and the large amount of healthy forehead skin that is lost when the pedicle is divided&#46; However&#44; despite this considerable loss of forehead tissue&#44; the defect can often be closed directly or by the advancement of adjacent tissues&#44; with no major cosmetic repercussions&#46;<a class="elsevierStyleCrossRef" href="#bib0120"><span class="elsevierStyleSup">2</span></a></p><p id="par0150" class="elsevierStylePara elsevierViewall">Finally&#44; the paramedian forehead flap can give rise to specific sequelae due to its particular anatomic features&#59; important sequelae are the transposition of forehead hair &#40;<a class="elsevierStyleCrossRef" href="#fig0020">Figure 4</a>&#41; and excessive flap thickness &#40;<a class="elsevierStyleCrossRef" href="#fig0025">Figure 5</a>&#41;&#46; The transposition of hairy skin from the scalp to the area of the nose occurs in patients with a low hairline&#59; this can be resolved later by electrolysis or laser treatment of the hair follicles&#46; Excessive flap thickness is the most common sequela&#46; The main preventive measure is surgical thinning of the flap&#46; Although this can be performed early &#40;during dissection of the flap or when the pedicle is divided&#41;&#44; postponement is recommended in patients with vascular risk factors in order to avoid compromising the viability of the donor tissue&#46; Corticosteroid infiltration in the thickened area can also accelerate the thinning process&#46;<a class="elsevierStyleCrossRef" href="#bib0205"><span class="elsevierStyleSup">19</span></a> However&#44; excessive thickness resolves spontaneously over the first year in a large percentage of cases&#44; and many authors therefore recommend a conservative approach&#46;</p><elsevierMultimedia ident="fig0020"></elsevierMultimedia><elsevierMultimedia ident="fig0025"></elsevierMultimedia><p id="par0155" class="elsevierStylePara elsevierViewall">Our experience has revealed some clues to the optimization of flap results&#46; An appropriate design and a meticulous technique are essential to ensure the blood supply and viability of the flap&#46; The design is based on the supratrochlear artery&#44; which ascends vertically in the paramedian region &#40;2<span class="elsevierStyleHsp" style=""></span>cm from the midline&#41; over the frontalis muscle&#46; Distally&#44; its terminal branches are connected to the vessels of the subdermal plexus of the scalp&#46; However&#44; the most proximal segment of the supratrochlear artery descends between the orbicularis oculi and corrugator muscles to reach the periosteal plane&#46; Here the artery anastomoses with branches of the angular and supraorbital arteries&#46; Meticulous dissection of the flap will preserve the 3 vessels&#44; maximizing blood flow to the pedicle&#46;<a class="elsevierStyleCrossRef" href="#bib0130"><span class="elsevierStyleSup">4</span></a> Designing the flap to respect the anatomic subunits of the nose<a class="elsevierStyleCrossRefs" href="#bib0210"><span class="elsevierStyleSup">20&#44;21</span></a> allows the incisions to be concealed in the borders between these subunits&#44; thus improving the cosmetic results&#46; Finally&#44; procedures for secondary review&#44; such as dermabrasion of the skin surface&#44; can improve the cosmetic result and achieve a more homogeneous appearance<a class="elsevierStyleCrossRefs" href="#bib0215"><span class="elsevierStyleSup">21&#44;22</span></a> in those cases in which this is required&#46;</p><p id="par0160" class="elsevierStylePara elsevierViewall">The limitations of our study stem from its retrospective design and the small size of the sample&#46; Further studies are necessary to analyze the factors associated with possible complications&#44; such as measures of the subjective evaluation by the patient &#40;perception of changes in quality of life and tolerance of or satisfaction with the results&#41;&#46;</p><p id="par0165" class="elsevierStylePara elsevierViewall">In conclusion&#44; the paramedian forehead flap is a useful&#44; safe&#44; and versatile technique&#46; Its main indication is for the repair of nasal tissue defects with a diameter greater than 1&#46;5<span class="elsevierStyleHsp" style=""></span>cm&#44; which exceed the possibilities of local flaps&#44; particularly when the defects affect the full thickness of the wall &#40;skin&#44; cartilage&#44; and mucosa&#41;&#46; Optimization of results depends on the use of a careful technique and preservation of the cosmetic subunits &#40;<a class="elsevierStyleCrossRef" href="#fig0030">Figure 6</a>&#41;&#46;
