Characterizing Olfactory Dysfunction in Patients with Unilateral Cleft Lip Nasal Deformities.

Background: Unilateral cleft lip nasal deformity (uCLND) is associated with olfactory dysfunction, but the underlying etiology remains poorly understood. Objective: To investigate the etiology of uCLND-associated olfactory dysfunction using clinical, computational, and histologic assessments. Methods: Inclusion criteria: uCLND patients >16 years undergoing septorhinoplasty. Exclusion criteria: prior septoplasty or rhinoplasty, pregnancy, sinusitis. Measured outcomes: patient-reported scores, rhinomanometry, smell identification and threshold tests, computational fluid dynamics (CFD) airflow simulations, and histologic analysis of olfactory epithelium. Results: Five uCLND subjects were included: 18-23 years, three male and two female, four left-sided cleft and one right-sided cleft. All subjects reported moderate to severe nasal obstruction. Smell identification and threshold tests showed varying degrees of hyposmia. Nasal resistance was higher on the cleft side versus noncleft side measured by rhinomanometry (median 3.85 Pa-s/mL, interquartile range [IQR] = 21.96, versus 0.90 Pa-s/mL, IQR = 5.17) and CFD (median 1.04 Pa-s/mL, IQR = 0.94 vs. 0.11 Pa-s/mL, IQR = 0.12). Unilateral olfaction varied widely and was dependent on unilateral percentage olfactory airflow. Biopsies revealed intact olfactory neuroepithelium. Conclusions: uCLND-associated olfactory dysfunction appears to be primarily conductive in etiology and highly susceptible to variations in nasal anatomy.

Early Simultaneous Cross Facial Nerve Graft and Masseteric Nerve Transfer for Facial Paralysis after Tumor Resection.

We describe a new approach for facial reanimation after skull base tumor resection with known facial nerve sacrifice, involving simultaneous masseter nerve transfer with selective cross facial nerve grafting (CFNG) within days after tumor surgery. This preliminary study compared outcomes of this approach versus a staged procedure involving a masseter nerve "babysitter" performed in a delayed timeline. Methods: Patients undergoing masseter nerve transfer and CFNG for facial paralysis after skull base tumor resection were consented to participate in video interviews. Facial Clinimetric Evaluation (FaCE) Scale (0-100) patient-reported outcome, eFACE, and Facial Grading Scale scores were compared. Results: Nine patients had unilateral facial paralysis from resection of a schwannoma (56%), acoustic neuroma (33%), or vascular malformation (11%). Five underwent early simultaneous CFNG and masseter nerve transfer (mean 3.6 days after resection), whereas four underwent two-stage reanimation including a babysitter procedure (mean 218 days after resection). Postoperative FaCE scale and Facial Grading Scale scores were similar in both groups (P > 0.05). Postoperative mean eFACE scores were similar for both groups for smile (early: 71.5 versus delayed: 75.5; P = 0.08), static (76.3 versus 82.1; P = 0.32), and dynamic scores (59.7 versus 64.9; P = 0.19); however, synkinesis scores were inferior in the early group (76.4 versus 91.1; P = 0.04). Conclusions: Early simultaneous masseter nerve transfer and CFNG provides reanimated movement sooner and in fewer stages than a staged approach in a delayed timeline. The early technique appears to result in similar clinician- and patient-reported outcomes compared with delayed procedures; however, in this preliminary study, the early approach was associated with greater synkinesis, meriting further investigation.

Defining Our Terms: Are Postoperative Complications Adequately Defined in the Rhinoplasty Literature?

BACKGROUND: Rhinoplasty is one of the most common aesthetic surgical procedures, and yet its postoperative complication profile remains somewhat ill-defined and underreported. The purpose of this study was to examine the quality of complication reporting in the rhinoplasty literature and provide a framework for future complication classification. METHODS: Studies were identified from a previously published 2019 systematic review conducted at Duke University Medical Center. Each included study was again reviewed to determine the reported complications and definitions. Reported complications were analyzed to determine occurrence rate, definition presence/absence, definition location, subjectivity/objectivity, and presence of severity grading system. RESULTS: A total of 30 studies were included. Overall, 63% (n = 19) of studies failed to provide a single definition for any reported complications. The remaining 11 studies (37%) provided at least one definition for their reported complications. Grading/severity scales were included by 8 studies. A specific complication was identified as a "primary outcome" in 15 cases. Definitions were included for 11 (73%) of these 15 complications. Complications denoted as "primary outcomes" were significantly more likely to have an included definition (p <0.01). CONCLUSIONS: Postoperative complications following rhinoplasty are inadequately defined in the available literature, with over sixty percent of studies failing to define a single-reported complication. When complication definitions are included, they are often subjective in nature and rarely include a grading or severity scale. In the absence of standardized rhinoplasty complication definitions, comparing complication rates across studies is exceedingly difficult, and the ability to conduct high-quality meta-analyses is limited.

Functional Nasal Surgery.

LEARNING OBJECTIVES: After studying this article, the participant should be able to: (1) understand the functional significance of nasal anatomy as it relates to rhinoplasty and perform a comprehensive functional nasal assessment. (2) Identify the anatomical level of obstruction based on the authors' algorithmic approach and understand the current evidence supporting operative techniques for correcting nasal airway obstruction from septal deformity, inferior turbinate hypertrophy, internal nasal valve collapse, external nasal valve collapse. (3) Understand the current evidence supporting operative techniques for correcting nasal airway obstruction from septal deformity, inferior turbinate hypertrophy, internal nasal valve collapse, and external nasal valve collapse. (4) Appreciate the objective assessment tools for functional nasal surgery from a clinical and research perspective. SUMMARY: The intent of functional rhinoplasty is to improve nasal airflow (and the perception thereof) by surgically correcting the anatomical sources of obstruction in the nasal airway. Cosmetic and functional rhinoplasty are not mutually exclusive entities, and the techniques that address one area, inevitably may affect the another. The rate of functional problems after cosmetic rhinoplasty range from 15 to 68 percent with nasal airway obstruction found to be the most common indication for secondary surgery. The objective of this CME article is to provide readers with an understanding of the (1) functional components of nasal anatomy, (2) clinical functional assessment, and (3) the current evidence supporting corrective maneuvers for each component.

A systematic analysis of surgical interventions for the airway in the mature unilateral cleft lip nasal deformity: a single case study.

PURPOSE: Individuals with unilateral cleft lip nasal deformity (uCLND) often require rhinoplasty in adolescence to correct nasal obstruction. The intent of this study is to identify sites of greatest nasal obstruction and evaluate the effects of isolated and combinations of simulated surgical procedures on these sites using computational fluid dynamics (CFD). METHODS: Computed tomography imaging of an adolescent subject with uCLND was converted to an anatomically accurate three-dimensional nasal airway model. Initial analysis was performed to identify anatomic sites of obstruction based on CFD computed resistance values. Virtual surgery procedures corresponding to common uCLND surgical interventions were simulated. Resulting airspace models were then analyzed after conducting airflow and heat transfer simulations. RESULTS: The preoperative model had 21 obstructed sites with a nasal resistance of 0.075 Pa s/mL. Following simulated surgical procedures with functional interventions alone and in combinations, the three virtual surgery models with most improved nasal airflow were inferior turbinate reduction (ITR) with posterior septoplasty (resistance = 0.054 Pa s/ml, reduction in 14 of 21 obstructed sites), ITR with anterior septoplasty (resistance = 0.058 Pa s/ml, reduction in 8 of 21 obstructed sites), and ITR with both anterior and posterior septoplasty (resistance = 0.052 Pa s/ml, reduction in 17 of 21 obstructed sites). CONCLUSION: This study introduces a new technique for analysis of the impact of different simulated surgical interventions on uCLND-induced nasal obstruction. In this subject, simulated septoplasty with ITR on the non-cleft side provided maximal relief of nasal obstruction. The proposed technique can be further studied for possible utility in analyzing potential surgical interventions for optimal relief of nasal obstruction in patients with uCLND.

Dorsal Hump Reduction and Midvault Reconstruction.

Dorsal hump reduction is one of the most common techniques used in modern rhinoplasty, yet it carries a high propensity for untoward aesthetic and functional sequelae, as evidenced by a nontrivial revision rate. Component dorsal hump reduction with stepwise deconstruction and manipulation of component parts allows for an adaptable and precise approach to variances in anatomy and in desired aesthetic result. Secondary changes must be anticipated and addressed at the index operation to avoid negative results and prevent the need for revision. Adequate reconstruction of the midvault is paramount to achieving optimal aesthetic and functional outcomes.

Cutaneous Reconstruction of the Nasal Distal Third: Alternative Local Flaps for a Complex Region.

Small-to-medium cutaneous defects of the distal nose pose a significant challenge to reconstructive surgeons, and commonly described reconstructive techniques have their limitations. As the skin of this region is characteristically rigid and sebaceous, care must be taken to avoid introducing unfavorable tension vectors that can result in functional or anatomic distortion of the nasal free margins. With this in mind, the authors discuss 3 alternative reconstructive options, the East-West, nasalis sling, and trilobed flaps, which have wide utility in the repair of distal nasal cutaneous defects and can result in excellent cosmesis. The indications, surgical technique, and limitations of each are discussed in detail, and are compared with several of the more commonly described options in the context of distal nasal reconstruction.

Two or Three? Approaches to Staging of the Paramedian Forehead Flap for Nasal Reconstruction.

The paramedian forehead flap is a historic cornerstone of plastic surgery and a mainstay of complex nasal reconstruction. Although initially described as a 2-stage procedure, several procedural advancements and modifications have been proposed, with the most notable being the addition of a third, intermediate stage. Proponents of this 3-stage approach argue that the addition of an intermediate stage improves flap perfusion, expands lining and structural support options, and provides superior aesthetic outcomes. Although this technique has grown in popularity, studies comparing the 2- versus 3-stage approach are relatively scarce in the literature. Existing comparative studies seem to suggest that the 3-stage paramedian forehead flap may have advantages in large, complex nasal defects and patients at high risk for vascular compromise. Additionally, comparative analyses with respect to aesthetic outcome were found to be largely equivocal, suggesting that surgeon comfort and preference should guide flap selection.

The Association between Away Rotations and Rank Order in the Integrated Plastic Surgery Match.

BACKGROUND: Given the competition in the integrated plastic surgery Match, away rotations are ubiquitous among plastic surgery applicants to differentiate their applications. This study aimed to characterize how performing an away rotation affects rank order and Match outcomes for integrated plastic surgery programs. METHODS: An online survey was designed and distributed to the top 25 integrated plastic surgery programs in the United States as determined by Doximity. Programs were polled about away rotation structure, position of rotators on their 2018 to 2019 rank list, and composition of current resident classes. RESULTS: Twenty-five programs completed the survey (response rate, 100 percent). On average, programs interviewed 34.9 applicants (range, 22 to 50 applicants) and ranked 32.8 applicants (range, 10 to 50 applicants). Most "ranked-to-match" positions were occupied by home students or away rotators (60.9 percent). Rank order of home students, away rotators, and nonrotators varied significantly (p < 0.001), with median rank order of home students [5 (interquartile range, 1 to 9)] and rotators [14 (interquartile range, 6 to 27)] higher than nonrotators [17 (interquartile range, 10 to 29)]. Rank orders of away rotators tended to follow a bimodal distribution. Furthermore, 64.4 percent of integrated residents were either a home student or away rotator at their matched integrated program, with 20 percent of residency programs composed of greater than 70 percent of away rotators/home students across postgraduate years 1 through 6 classes. CONCLUSIONS: For integrated plastic surgery programs, the majority of ranked-to-match students on rank lists and current residents were either home students or away rotators at their respective program. Performing well on an away rotation appears to confer significant benefit to the applicant applying in the integrated plastic surgery Match.

Systematic Review of Tissue Expansion: Utilization in Non-breast Applications.

BACKGROUND: Tissue expansion is a versatile reconstructive technique providing well-vascularized local tissue. The current literature focuses largely on tissue expansion for breast reconstruction and in the context of burn and pediatric skin/soft tissue replacement; however, less traditional applications are also prevalent. The aim of this study was to systematically review the utilization of tissue expansion in such less well-characterized circumstances. METHODS: The authors conducted a systematic review of all publications describing non-breast applications of tissue expansion. Variables regarding expander specifications, expansion process, and complications were collected and further analyzed. RESULTS: A total of 565 publications were identified. Of these, 166 publications described tissue expansion for "less traditional" indications, which fell into 5 categories: ear reconstruction, cranioplasty, abdominal wall reconstruction, orthopedic procedures, and genital (penile/scrotal and vaginal/vulva) reconstruction. While lower extremity expansion is known to have high complication rates, tissue expander failure, infection, and exposure rates were in fact highest for penile/scrotal (failure: 18.5%; infection: 15.5%; exposure: 12.5%) and vaginal/vulva (failure: 20.6%; infection: 10.3%; exposure: 6.9%) reconstruction. CONCLUSIONS: Tissue expansion enables index operations by providing additional skin before definitive reconstruction. Tissue expanders are a valuable option along the reconstructive ladder because they obviate the need for free tissue transfer. Although tissue expansion comes with inherent risk, aggregate outcome failures of the final reconstruction are similar to published rates of complications without pre-expansion. Thus, although tissue expansion requires a staged approach, it remains a valuable option in facilitating a variety of reconstructive procedures.

Tip Ligament Preservation and Suspension: Why and How?

This issue of Clinics explores the concept of "preservation" rhinoplasty. At present, this topic is gaining considerable attention. As proponents of preservation suggest, a great number of problems we encounter in rhinoplasty are problems that were not present before the surgery; therefore, they can often be attributable to the deconstruction and reconstruction that took place. Preservation rhinoplasty should be viewed generally as a mindset to limit deconstructive steps in rhinoplasty when possible, understanding that these steps and those to later reconstruct provide the potential to create new problems that did not previously exist.

Videoscope-Assisted Cleft Palate Surgery: Rationale, Experience, and Technical Implementation.

Limited visibility characteristic of cleft palate repair presents both ergonomic and educational challenges to cleft surgeons. Despite widespread recognition and reporting, posture-related spine disorders continue to represent a significant and potentially career-limiting problem for cleft/craniofacial surgeons. In addition, education and participation during palate repairs is difficult because of visual field constraints. At the authors' institution, a novel videoscope system was designed and implemented to (1) provide visualization for all surgical team members during palate operations, (2) facilitate active resident education, and (3) improve surgeon ergonomics. The authors' prior report demonstrated proof of concept for this method, which is now used in all cleft palate operations at their center. The purpose of this report is to share the detailed methodology to facilitate implementation by others and a retrospective review of the authors' experience before and after implementation. Video demonstration of the videoscope setup and a representative, recorded case are provided. The use of the videoscope was feasible in palatoplasties regardless of palatal phenotype and repair technique and did not have an effect on operative time. Subjectively, the authors report reduced procedure time in cervical flexion and subjectively improved musculoskeletal strain associated with videoscope use. Importantly, use of this system also provided complete visualization for all operating room team members and enabled enhanced resident autonomy during palate operations. Finally, it has facilitated the creation and archive of high-definition educational videos with unparalleled perspective. The equipment required to implement the system is likely already available in many medical centers. Adoption of this system may provide an opportunity to improve posture and teaching capabilities for cleft surgeons. CLINICAL QUESTION/LEVEL OF EVIDENCE:: Therapeutic, III.

Feasibility of Surgeon-Delivered Audit and Feedback Incorporating Peer Surgical Coaching to Reduce Fistula Incidence following Cleft Palate Repair: A Pilot Trial.

BACKGROUND: Improving surgeons' technical performance may reduce their frequency of postoperative complications. The authors conducted a pilot trial to evaluate the feasibility of a surgeon-delivered audit and feedback intervention incorporating peer surgical coaching on technical performance among surgeons performing cleft palate repair, in advance of a future effectiveness trial. METHODS: A nonrandomized, two-arm, unblinded pilot trial enrolled surgeons performing cleft palate repair. Participants completed a baseline audit of fistula incidence. Participants with a fistula incidence above the median were allocated to an intensive feedback intervention that included selecting a peer surgical coach, observing the coach perform palate repair, reviewing operative video of their own surgical technique with the coach, and proposing and implementing changes in their technique. All others were allocated to simple feedback (receiving audit results). Outcomes assessed were proportion of surgeons completing the baseline audit, disclosing their fistula incidence to peers, and completing the feedback intervention. RESULTS: Seven surgeons enrolled in the trial. All seven completed the baseline audit and disclosed their fistula incidence to other participants. The median baseline fistula incidence was 0.4 percent (range, 0 to 10.5 percent). Two surgeons were unable to receive the feedback intervention. Of the five remaining surgeons, two were allocated to intensive feedback and three to simple feedback. All surgeons completed their assigned feedback intervention. Among surgeons receiving intensive feedback, fistula incidence was 5.9 percent at baseline and 0.0 percent following feedback (adjusted OR, 0.98; 95 percent CI, 0.44 to 2.17). CONCLUSION: Surgeon-delivered audit and feedback incorporating peer coaching on technical performance was feasible for surgeons.
