RE: Abstract: Techniques in Rhinoplasty
Approximately six or seven years ago I had the pleasure and opportunity to have Dr.
Steve Dayan spend the year with me as a fellow in my practice at the Meridian Plastic
Surgery Center in Indianapolis, Indiana. Rhinoplasty procedures constituted
approximately one-third of my facial plastic surgery practice at the time Steve was with
me and continues to be about twenty-five to thirty-five percent of my total practice
volume. I am still performing the same number of rhinoplasties on an annual basis as I
did eleven years ago, but other aging face procedures, with particular emphasis on
increasing numbers on lesser invasive procedures, have grown within the practice.
Rhinoplasty is and always has been the most challenging facial plastic surgery
procedure that I perform and remains the most difficult procedure to teach young
developing facial plastic surgeons. I agree with Dr. Dayan that rhinoplasty is a highly
complex procedure which he describes as having a steep learning curve. My opinion
differs because I believe that rhinoplasty is an operation that has one of the least steep
learning curves of all the procedures we do. It takes an entire career to even begin to
learn the nuances of the rhinoplasty operation and even longer to consistently predict its
long-term results. Aging face procedures are picked up fairly rapidly with a very steep
learning curve which allows the finishing fellow in my fellowship to leave the practice
well prepared to perform most any aging face procedure that we do. Whereas, most of
the fellows are still trying to get a feel for how to execute the multitude of techniques that
make a difference between good and excellent rhinoplasty results.
Rhinoplasty remains a very humbling operation even for the more experienced
surgeons who are considered masters in the field. Over the past six to ten years, my
personal abilities to perform this operation have exponentially increased compared to the
first two-thirds of my years in private practice. Most of this is due to the critical
evaluation of the results of rhinoplasties I performed years ago. At that time, I believed I
was doing very appropriate surgical maneuvers taught by my mentors, who were very
experienced rhinoplasty surgeons themselves. In addition, I have continued to be a
student of the operation and have attended every rhinoplasty meeting that the Academy
has offered and have participated as a faculty member as well. Every time I attend a
meeting I improve my skills and abilities to recognize potential problems in rhinoplasty
as well as adding modified, if not new, procedures to improve the overall long-term
results. As one of the more mature surgeons, with twenty plus years of experience, I have
been afforded the opportunity to see and examine long term results from my own practice
experience. Many times patients return to me and the practice for some other facial
plastic surgery concern, such as aging face, and have been satisfied, content, and
essentially happy with their rhinoplasty results. However, I would evaluate some of these
results from a surgeon’s perspective and react with a certain degree of “horror”.
Changes that occurred over time demonstrated that reduction rhinoplasty needs to be
extremely conservative and many of the things that I believed and were taught needed to
have another critical assessment. My rate of revision rhinoplasty still is between three
and five percent of my rhinoplasty practice, as it was six to seven years ago. If I were to
choose for the patient, my revision rate would probably rise to twenty-five to thirty
percent of the rhinoplasties I performed greater than ten years ago. Within my practice,
revision or secondary rhinoplasty still is only about thirty-five to forty percent of my
total number of rhinoplasties.
Often patients do not know that a revision can be performed which could give them
more satisfactory results. In addition, they often have had an uncomfortable, if not
miserable, experience from the first operation and do not believe they want to undergo
another one. Furthermore, the cost of the revision rhinoplasty is more than a primary
rhinoplasty and significantly more than they paid several years ago. These factors limit
the total numbers of secondary rhinoplasties that could be performed.
Secondary rhinoplasty affords us the opportunity to learn from what we see as “others’
mistakes”, but we also learn from our own by following patients for at least ten years and
longer. My basic philosophical approach to the rhinoplasty operation is essentially the
same as it was when Dr. Dayan spent a year in fellowship with me. My personal
approach to the rhinoplasty operation involves the combined and intermixed use of the
endonasal approach and the external columellar approach to give each individual patient
their optimal immediate and long-term outcome.
I was taught the endonasal delivery flap approach to tip rhinoplasty, and I still
thoroughly enjoy this approach, however, my practice of the endonasal approach has
decreased over the past six to seven years from approximately sixty or seventy percent of
my primary rhinoplasties to about thirty to forty percent. There are specific reasons for
performing more external columellar approach – primarily being recognition of the
need for preventative structural grafting and the ease with which these grafts are placed
through the external columellar approach. It has also become apparent that grafting in
the nasal lobule for prevention of late untoward changes has necessitated the external
columellar approach in increasing numbers of cases.
Not only has evaluating the long term results in tip rhinoplasty affected my choice as
to the external columellar approach or the endonasal approach, but so has the nasal
pyramid. In fact, it is the nasal pyramid that has increased the number of external
columellar approaches I perform more so than maintenance of external nasal valve and
alar cosmetic competency. The traditional cephectomy operation performed for hump
removal has been changed significantly in my hands in order to prevent delayed
occurrence of an “hourglass” visible deformity.1 This inverted V deformity is not
usually due to the dislocation of the upper lateral cartilages from the nasal bones, but is
caused by the inevitable contracture of scar tissue overpowering the strength of the
disarticulated upper lateral cartilages from the dorsal septum. The central cicatricial
inward contraction either results in unilateral or bilateral depressions of the mid nasal
dorsum. In addition, with the upper lateral cartilages falling away from the septum, there
have been more dorsal ridges and irregularities visible over time. Shrink-wrapping of the
skin envelope is particularly evident after five years and highlights dorsal irregularities
that were otherwise not noticed in the first two years of follow-up.2
Recognition of the preexisting condition of the nasal pyramid consisting of a tall,
narrow hump with thin skin and short nasal bones, predisposing to long term inverted V
deformities increases the number of external approaches.
Recognition of a preexisting condition in a lobule has also increased the use of the
external columellar approach with grafting to prevent external nasal valvular collapse and
recurvature of the lower lateral cartilages internally. The weakened, collapsing alar
cartilages create visible deformities of the ala as well as airway obstruction. To prevent
the pyramid deformities that have occurred, I have significantly increased the use of
spreader grafts, which are much easier to suture in place through the external columellar
approach than endonasal.3 Alar strut grafts, which are placed between the vestibular skin
and the alar cartilage, are significantly easier to place from the cephalic direction using
an external columellar incisional approach than from the caudal aspect. These grafts
support the lateral ala and correct the preexisting cephalic malposition of the alar
cartilage.4 This is currently a more recognizable preoperative deformity that lends itself
to late recurvature or collapse of the external nasal valve.5 By placing the alar strut graft,
the airway is maintained and the nasal contour is also maintained.6
Finally, I have recognized that many primary rhinoplasty patients have markedly
asymmetrical alar cartilages from the medial crura to the intermediate crura. Using an
endonasal approach to suture these together can create twists, asymmetries, irregularities
in both the nostril shape as well as the columella itself.
I have most frequently divided the intermediate and medial crura, either symmetrically
or asymmetrically, to create improvements in the projection and symmetry of the lobule.
The Lipsett or modified Lipsett procedure is performed much more easily through an
external columellar incision.7
Therefore, it is the more experienced rhinoplasty surgeon who can learn to recognize
preexisting conditions which are “setups” for pyramid abnormalities. Recognizing
cephalic malposition of the alar cartilages with extremely convex cartilages as one of
these problematic preexisting conditions requires a plan to correct and prevent this.8
Convex nasal cartilages are often best corrected with alar spanning sutures which, again,
are placed much more easily under direct vision through the external columellar
approach.9 Prior to six or seven years ago, I either never or very rarely placed an alar
spanning suture. (This has been a great addition to the narrowing and defining of strong
convex lower lateral cartilages.)
Understanding tip projection and maintaining this is fundamental to the rhinoplasty
operation. This has not changed in the last six to seven years. Nasal tip projection
should not be compromised by endonasal delivery flap approaches. It is easier to
maintain tip projection and place stronger columellar struts, if required, through the
external columellar approach. Both techniques use tip sculpting techniques as well
as strut grafting, and reestablishing medial crural septal relationship to maintain, if not
improve, tip projection.
Handling the Crooked Nose
An asymmetrical or crooked nose that is either C-shaped or angled on a congenital
basis, has been a difficult problem for all rhinoplasty surgeons.10 It is a problem that I
did not correct very satisfactorily early on in my practice. In the past ten to twelve years,
I have increased the use of a variety of osteotomy techniques to correct the angled nose.
I learned the use of double or intermediate osteotomies on the long sloping side of the
nose during my fellowship. However, it has only been within the past seven years that I
have learned to effectively use a transverse root osteotomy via a transcutaneous approach
in order to correct deviations that start from the nasion to the rhinion. More freely using
spreader grafts as well as onlay grafts on top of spreader grafts to camouflage midnasal
dorsal curvatures has assisted in obtaining a much straighter nose postoperatively.
Understanding the use of asymmetrical suture techniques between the septum and upper
lateral cartilages has also assisted in straightening some of these dorsal curvatures.
For curvatures of the caudal septum, which are a problem in terms of recurrence, I
have increased the use of permanent sutures holding the caudal septum to the periosteum
of the anterior nasal spine. I use a 5-0 clear prolene suture. This base septal columellar
suture can be incorporated with a “tongue in groove” technique, if required, in order to
hold the caudal septum between the medial crura and to straighten the columella. I no
longer entirely rely on a temporary 3-0 chromic suture. I have increased the use of
caudal extension grafts for lengthening the short nose and the retruded columella.
In terms of lengthening the short nose, I use a variety of techniques, including the use
of the “cantilever” spreader graft to push the whole lobule in a more caudal, inferiorly
rotated direction.11 Long, extended spreader grafts that extend past the caudal septal
angle are sutured to a strong septal cartilage strut, pushing the lobule inferiorly.12 I have
never performed or favored the complete removal of the septum to modify it ex-vivo and
then replace the septum as a “total” free graft.
Profile-plasty
Over the past ten years, I have recognized the significant assistance of radix grafts to
profile-plasty. A low nasal frontal angle can cause the illusion of a nose that appears to
be all lobule.13 Radix grafts minimize the height reduction of the cartilaginous and bony
dorsum, which is required to maintain its integrity and strength while still giving a
straight profile alignment.14 Maintaining dorsal integrity has been a goal in profile-plasty
over the years but has been particularly emphasized in the last five to six years. I no
longer remove the cartilaginous and bony dorsum en bloc, nor do I remove the
cartilaginous dorsum en bloc with the upper lateral cartilage and septum with the single
cut of an eleven blade. I specifically, individually separate the mucoperichondrium from
the under surface of the upper lateral cartilages where they join the septum. I make a
pocket to maintain the integrity of the mucoperichondrium in nearly all cases. I then
separate the upper lateral cartilages from the septum and maintain the height of the upper
lateral cartilages until I am absolutely certain they need to be reduced. I reduce the
cartilaginous dorsum separately from the bony dorsum and, finally, if necessary, reduce
the height of the upper lateral cartilages. Sometimes I use the upper lateral cartilages by
folding them inward, acting as auto spreader grafts, maintaining mid dorsal strength and
width.
I much more frequently place crushed cartilage grafts placed freely over the rhinion,
bony hump reduced region, and supratip region to improve the dorsal soft tissue
envelope. I rarely count on Alloderm or a cadaveric collagen grafts for persistence in
thickening the overlying fibrous soft tissue envelope. I went through a period of using
Alloderm for this reason and was disappointed in the long term results , particularly after
three to four years. I do not hesitate to use a 1.0 millimeter Gore-Tex® graft for a
blanket graft to camouflage irregularities, particularly in revision rhinoplasty.15 I have
also wrapped more of the radix grafts with temporalis fascia in order to soften the
interface of the cartilage in the nasal frontal angle region. I do not hesitate to use
crushed cartilage as plumper grafts in the tip region as well. I have certainly increased
the use of soft tissue overlay grafts and almost routinely use these when tip grafts are
used, including cap grafts and blocking grafts in thin skinned individuals.16 Any increase
in thickness to the soft tissue envelope, I think is critical to improve long term results.
In summary, with regards to the nasal lobule, the recognition of weak alar side walls
in the preoperative condition is critical to improving long-term results. This may be
merely that the alar margin is a bit weak.17 In my practice, placement of alar rim grafts
has increased ten-fold in the past three to four years. These are small grafts placed near
the end of the operation in a small defined pocket along the alar margin, giving a little
more strength and straightening to an otherwise weak alar margin.18 If the alar cartilages
are cephalically malpositioned or there is a tendency for recurvatuare, even in the preop
condition, the placement of alar strut grafts is planned. These are different than alar
batten grafts placed on top of the alar cartilages for additional support to the alar
cartilage. These grafts are actually struts themselves, merely preventing the weak alar
cartilages from falling inward, creating a recurvatuare phenomenon and alar valve
collapse. Finally, recognizing that double dome suturing techniques do not by
themselves solve the problem of adequately narrowing the nasal supratip lobule in
patients with convex, strong alar cartilages. In addition to potentially placing alar strut
grafts, one must use alar spanning sutures to bring these convex portions of the cartilage
inward, maintaining structural support to the alar cartilage itself. No longer should one
morselize or otherwise weaken the lateral alar cartilage. These have been a great addition
to lobuloplasty in the past four years.
Conclusion
The evolution of my rhinoplasty practice over the past six to ten years has been dramatic.
The increasing use of small grafts, if not structural grafts, to maintain or prevent late
problems has been paramount to improved results that stand the test of time. These grafts
are easier to place through the external columellar incision, and I have increased the use
of my “open approach” approximately twenty percent. However, I still thoroughly enjoy
the endonasal approach to primary rhinoplasty when the patient’s condition warrants.
This makes for a very straightforward and fairly short operation achieving maximum
aesthetic results with minimum postoperative down time for the patient. I believe the
mature (experienced) rhinoplasty surgeon needs to be able to perform this operation via
either the external columellar approach or an endonasal approach to maximally serve
his/her entire patient population. It is unfortunate if a young rhinoplasty surgeon is not
exposed to the beauty of the endonasal operation. I will continue to perform this
approach and develop ways to increase grafting and maintain support in the mid nasal
vault and alar sidewalls while still doing endonasal approach rhinoplasty.
