P: (617) 523-7900 Abstract
Purpose: Lateral osteotomies are important during rhinoplasty and represent a challenging technique that otolaryngology and plastic surgery trainees must learn. The approaches for
IP
T
osteotomies are difficult to teach as they are accomplished through tactile feedback. Trends in
CR
teaching and practice patterns of lateral osteotomies are poorly described in the literature, and this study aims to fill this knowledge gap.
US
Materials and methods: Members of the American Academy of Facial Plastic and Reconstructive Surgery were surveyed to characterize surgeon preferences for intranasal versus
AN
percutaneous lateral osteotomies and understand how techniques are taught.
M
Results: Among surgeons who completed the survey (n=172), 87% reported that they “always”
ED
or “mostly” use intranasal lateral osteotomies whereas only 8% “always” or “mostly” use percutaneous approaches. There is no significant trend towards changing osteotomy techniques
PT
when teaching trainees. Only 15% of respondents allow trainees to perform lateral osteotomies in more than half of operations.
CE
Conclusions: Most facial plastic surgeons prefer to use intranasal lateral osteotomies. However,
AC
many do not allow trainees to perform this critical step during rhinoplasty. This study has implications for both patient care and surgical education.

1.0 Introduction Lateral osteotomies are essential to functional and cosmetic rhinoplasties and can be performed through percutaneous or transnasal approaches. While some surgeons find a percutaneous approach enables a more controlled fracture and minimizes deep tissue trauma [1],
IP
T
others posit that an intranasal approach minimizes morbidity and avoids scarring [2]. Both techniques are important, but difficult to teach, , as they are performed through tactile feedback,
CR
although there is limited literature characterizing this problem. The complications of an
US
incorrectly performed osteotomy include poor aesthetic results as well as poor functional outcomes. Incorrectly performed osteotomies are difficult to correct.
AN
Given the difficulty inherent in teaching these surgical techniques, we sought to better
M
characterize how lateral osteotomies are performed and taught nationwide. This study offers an
ED
up to date understanding of how osteotomies are currently performed by facial plastic surgeons and highlights areas for improvement in surgical education.

2.0 Methods

This project was approved by the Massachusetts Eye and Ear Infirmary institutional
AC
review board. A survey was designed using Qualtrics Software (Provo, UT) and distributed via e-mail by the American Academy of Facial Plastic and Reconstructive Surgery (AAFPRS) to ~1100 members between September and November 2015. Participation was voluntary and responses were anonymous. Survey data were analyzed with descriptive and analytic statistics using Graphpad Prism (La Jolla, CA) and multivariable regressions were performed using Wessa.net (online version 1.1.23-r7). Paired t-tests were used to determine if surgeons changed osteotomy technique when teaching trainees as compared to when operating alone. Multivariable
ACCEPTED MANUSCRIPT 4
regressions determined variables associated with type of osteotomy used in current practice and type of osteotomy taught. Chi-squared tests were used to determine if timing of training is independent from techniques learned during training.

3.0 Results
IP
One-hundred and seventy two surgeons completed the survey. The average respondent
CR
performs 21 to 50 rhinoplasties annually and completed surgical training 16.3 years ago (SD=11, median=14, Figure 1a, b). 87% of respondents “always” or “mostly” perform intranasal lateral
US
osteotomies while 8% “always” or “mostly” use percutaneous approaches (Figure 1c). Similarly, 90% of respondents learned primarily to perform intranasal osteotomies during training (Figure
AN
1d). Notably, the proportion who received significant training in percutaneous techniques has
M
significantly increased among those who finished training in the last 15 years compared with
ED
those who trained earlier (16% vs. 4%, Chi-square test for independence p=0.01). The osteotomy approach preferred was associated with the type respondents learned during training (β=0.54,
PT
SD=0.13, p<0.001), whereas years since training (p=0.45) and rhinoplasties performed annually
CE
(p=0.34) were not associated.
Sixty-three percent of AAFRPS members who prefer an intranasal technique attribute
AC
this to their own training. Thirty-five percent think an intranasal technique provides a better outcome and 17% prefer an intranasal technique because there is no scarring; some believe it gives better control or a more complete osteotomy. Among those who prefer a percutaneous approach, 21% cite their prior training and 57% believe it gives a better outcome; some find there is a lower likelihood of flail segments or better accuracy and control in the cut.
ACCEPTED MANUSCRIPT 5
Among AAFRPS respondents, 74% of (n=128) teach trainees. Respondents do not change technique when teaching compared to when operating alone (paired t-test p=0.78). Technique used when operating alone is most associated with that used when teaching (β=0.94, SD=0.032, p<0.001). Factors not associated include years since training (p=0.75) and number of
IP
T
rhinoplasties performed annually (p=0.89). Of note, only 15% of respondents allow trainees to perform lateral osteotomies during
CR
more than half of operations (Figure 2). In comparison, significantly more respondents allow
US
trainees to perform septoplasties (52%, paired t-test p=<0.0001) or harvest auricular cartilage (58%, paired t-test p=<0.0001) during more than half of operations.
AN
4.0 Discussion
M
Among a sample of AAFRPS members, the majority prefer to perform and teach an
ED
intranasal approach to lateral osteotomies. The choice of techniques is most associated with training experiences. One interesting finding is that surgeons who have completed training in the
PT
past 15 years are more exposed to percutaneous techniques than those who completed training
CE
earlier. This may indicate an evolving understanding that both percutaneous and intranasal techniques are important for surgeons to master. Surgeons reported various and sometimes
AC
overlapping reasons for using one technique over another. This may be explained by variables such as patient factors, osteotome size [3], perforated vs. continuous cuts [2], and certainly surgical familiarity with each approach. Additional research comparing the functional and aesthetic outcomes of the two approaches may offer further insight. As the choice of technique is significantly associated with one’s own training, it may be important to expose current residents to both techniques.
ACCEPTED MANUSCRIPT 6
The most notable finding in this study is that very few surgeons allow trainees to perform osteotomies. Strategies should be explored to improve trainee education, particularly as the Accreditation Council for Graduate Medical Education requires graduating otolaryngology and plastic surgery residents to perform a minimum of only 8 or 10 rhinoplasties, respectively [4].
IP
experiences for plastic surgery and otolaryngology residents [5–7].
T
For example, using fresh tissue in surgical simulations has been shown to improve extraclinical
CR
This study is limited by its low response rate. However, this is typical for electronic
US
surveys of busy practicing physicians [8]. Despite this, there were sufficient respondents to power the aforementioned analyses. Moreover, the number of active members and accurate
AN
emails on the AAFPRS mailing list is unknown, such that the true response rate may be higher.
M
As for all voluntary surveys, this study may be limited by selection bias (i.e. those interested in
ED
rhinoplasty may have been more likely to respond). 5.0 Conclusion
PT
The majority of facial plastic surgeons surveyed preferred to perform and teach an
CE
intranasal approach to lateral osteotomies and are heavily influenced by the method they were exposed to during training. It is therefore concerning that trainees are often not allowed to
AC
practice these high risk procedures. Innovations in surgical education are necessary to address this gap in training.
