Complete Hemifacial Paralysis Post-facelift: Making Sense of a Plastic Surgeon's Worst Nightmare.

BACKGROUND: Postrhytidectomy hemifacial paralysis is a frightening clinical condition affecting the proximal facial nerve and most often associated with Bell's palsy. Associated symptoms are common and include auditory, salivary, vestibular, and gustatory complaints. OBJECTIVES: The aim of the study was to provide increased awareness of postrhytidectomy hemifacial paralysis secondary to Bell's palsy in the plastic surgery community. METHODS: Following a roundtable discussion with the senior author's (J.C.G.) plastic surgery colleagues located all over the world, 8 surgeons reported having had firsthand experience with hemifacial paralysis in patients following facelift. Descriptions of their cases, including preoperative, intraoperative, and postoperative courses were collected and reported. RESULTS: A total of 10 cases of postrhytidectomy hemifacial paralysis were analyzed based on results of a clinical questionnaire. Eight of the 10 cases involved all facial nerve branches, with 2 cases sparing the marginal mandibular branch. The vast majority of cases were referred to a neurologist and steroids initiated. Two patients were returned to the operating room for exploration. Associated symptoms reported included pain in the ear, hearing loss, ocular symptoms such as tearing or dryness, vestibular symptoms such as vertigo, changes in taste, and in 1 patient an electric-shock type sensation to the face. CONCLUSIONS: Hemifacial paralysis associated with Bell's palsy following rhytidectomy is a rare but known clinical entity that should be included in the preoperative informed consent process before facelift. Current management trends are neurology referral and steroid initiation.

Lifting the Anterior Midcheek and Nasolabial Fold: Introduction to the Melo Fat Pad Anatomy and Its Role in Longevity and Recurrence.

BACKGROUND: A limitation of current facelift techniques is the early postoperative reappearance of anterior midcheek laxity associated with recurrence of the nasolabial fold (NLF). OBJECTIVES: This study was undertaken to examine the regional anatomy of the anterior midcheek and NLF with a focus on explaining the early recurrence phenomenon and to explore the possibility of alternative surgical methods that prolong NLF correction. METHODS: Fifty cadaver heads were studied (16 embalmed, 34 fresh; mean age, 75 years). Following preliminary dissections and macrosectioning, a series of standardized layered dissections were performed, complemented by histology, sheet plastination, and microcomputed tomography. Mechanical testing of the melo fat pad (MFP) and skin was performed to gain insight on which structure is responsible for transmission of the lifting tension in a composite facelift procedure. RESULTS: Anatomic dissections, sheet plastination, and microcomputed tomography demonstrated the 3-dimensional architecture and borders of the MFP. Histology of a lifted midcheek demonstrated that a composite MFP lift causes a change in connective tissue organization from a hanging-down pattern into a pulled-upward pattern, suggesting traction on the skin. Mechanical testing confirmed that, in a composite lift, despite the sutures being placed directly into the deep aspect of the MFP, the lifting tension distal to the suture is transmitted through the skin and not through the MFP. CONCLUSIONS: The usual method of performing a composite midcheek lift results in the skin, and not the MFP itself, bearing the load of the nondissected tissues distal to the lifting suture. For this reason, early recurrence of the NLF occurs following skin relaxation in the postoperative period. Accordingly, specific surgical procedures for remodeling the MFP should be explored, possibly in combination with volume restoration of the fat and bone, for more lasting improvement of the NLF.

Upper Blepharoplasty and Brow Rejuvenation in Men.

The upper lid-brow junction is a complex anatomic zone that undergoes many interconnected age-related changes. Although considerable effort has gone into defining the ideal female eye and brow, no such work has been done for the male. Typically, men develop forehead and glabellar lines in conjunction with either upper lid hooding, brow ptosis, or blepharoptosis, whereas some men develop hollowing of the upper lid sulcus. Physical examination defines which features predominate. Treatment can be nonsurgical or surgical. The surgical options include upper lid blepharoplasty, various types of brow lifting or brow shaping, ptosis repair, and fat grafting.

Evaluating the impacts of contrasting sewage treatment methods on nutrient dynamics across the River Wensum catchment, UK.

Sewage effluent discharged from wastewater treatment plants (WWTPs) is a major driver of nitrogen (N) and phosphorus (P) enrichment, but tertiary treatment methods such as P-stripping have previously been shown to mitigate eutrophication risk. The aim of this study was to evaluate the impacts of sewage effluent discharged from WWTPs with contrasting classifications of tertiary treatment on nutrient dynamics across the River Wensum catchment, UK. River water samples were collected from 20 locations across the catchment at monthly intervals between October 2010 and September 2013, with 677 samples collected in total and analysed for a suite of hydrochemical parameters. The 20 sampling locations were divided into four classifications based on the type of upstream WWTP: (1) no WWTP; (2) WWTPs without P-stripping; (3) WWTPs with and without P-stripping; (4) WWTPs with P-stripping. Results revealed substantial overlaps in riverine nutrient composition making differentiation between classifications difficult. The majority of N (>97%) and P (~75%) was present in dissolved bioavailable forms across all sites and there was no significant difference in total N speciation between classifications. Total P (TP) speciation did, however, reveal higher proportions of particulate P at sites with no WWTP, indicating a greater P contribution of agricultural origin. Ratios of total dissolved to particulate P (TDP:TPP) and chloride concentrations proved effective discriminators of agricultural and sewage P, respectively, but phosphate­boron ratios (PO4:B) were ineffective discriminators in this catchment. Most importantly, there was no evidence that P-stripping reduced overall TP concentrations downstream of WWTPs, despite evidence of a per capita reduction, nor reduced the proportion of dissolved P released. These findings were attributed to P-stripping facilities serving larger populations and thus releasing greater effluent P load, thereby demonstrating that the presence of tertiary P-stripping alone is insufficient to overcome population pressures and ensure that rivers achieve good hydrochemical status.

Consensus of Leaders in Plastic Surgery: Identifying Procedural Competencies for Canadian Plastic Surgery Residency Training Using a Modified Delphi Technique.

BACKGROUND: Transitioning to competency-based surgical training will require consensus regarding the scope of plastic surgery and expectations of operative ability for graduating residents. Identifying surgical procedures experts deemed most important in preparing graduates for independent practice (i.e., "core" procedures), and those that are less important or deemed more appropriate for fellowship training (i.e., "noncore" procedures), will focus instructional and assessment efforts. METHODS: Canadian plastic surgery program directors, the Canadian Society of Plastic Surgeons Executive Committee, and peer-nominated experts participated in an online, multiround, modified Delphi consensus exercise. Over three rounds, panelists were asked to sort 288 procedural competencies into five predetermined categories within core and noncore procedures, reflecting increasing expectations of ability. Eighty percent agreement was chosen to indicate consensus. RESULTS: Two hundred eighty-eight procedures spanning 13 domains were identified. Invitations were sent to 49 experts; 37 responded (75.5 percent), and 31 participated (83.8 percent of respondents). Procedures reaching 80 percent consensus increased from 101 (35 percent) during round 1, to 159 (55 percent) in round 2, and to 199 (69 percent) in round 3. The domain "burns" had the highest rate of agreement, whereas "lower extremity" had the lowest agreement. Final consensus categories included 154 core, essential; 23 core, nonessential; three noncore, experience; and 19 noncore, fellowship. CONCLUSIONS: This study provides clarity regarding which procedures plastic surgery experts deem most important for preparing graduates for independent practice. The list represents a snapshot of expert opinion regarding the current training environment. As our specialty grows and changes, this information will need to be periodically revisited.

The Development of Assessment Tools for Plastic Surgery Competencies.

BACKGROUND: Objective tools to assess procedural skills in plastic surgery residency training are currently lacking. There is an increasing need to address this deficit in order to meet today's training standards in North America. OBJECTIVES: The purpose of this pilot study was to establish a methodology for determining the essential procedural steps for two plastic surgery procedures to assist resident training and assessment. METHODS: Following a literature review and needs assessment of resident training, the authors purposefully selected two procedures lacking robust assessment metrics (breast augmentation and facelift) and used a consensus process to complete a list of procedural steps for each. Using an online survey, plastic surgery Program Directors, Division Chiefs, and the Royal College Specialty Training Committee members in Canada were asked to indicate whether each step was considered essential or non-essential when assessing competence among graduating plastic surgery trainees. The Delphi methodology was used to obtain consensus among the panel. Panelist reliability was measured using Cronbach's alpha. RESULTS: A total of 17 steps for breast augmentation and 24 steps for facelift were deemed essential by consensus (Cronbach's alpha 0.87 and 0.85, respectively). CONCLUSION: Using the aforementioned technique, the essential procedural steps for two plastic surgery procedures were determined. Further work is required to develop assessment instruments based on these steps and to gather validity evidence in support of their use in surgical education.

Competency-based medical education for plastic surgery: where do we begin?

BACKGROUND: North American surgical education is beginning to shift toward competency-based medical education, in which trainees complete their training only when competence has been demonstrated through objective milestones. Pressure is mounting to embrace competency-based medical education because of the perception that it provides more transparent standards and increased public accountability. In response to calls for reform from leading bodies in medical education, competency-based medical education is rapidly becoming the standard in training of physicians. METHODS: The authors summarize the rationale behind the recent shift toward competency-based medical education and creation of the milestones framework. With respect to procedural skills, initial efforts will require the field of plastic surgery to overcome three challenges: identifying competencies (principles and procedures), modeling teaching strategies, and developing assessment tools. The authors provide proposals for how these challenges may be addressed and the educational rationale behind each proposal. RESULTS: A framework for identification of competencies and a stepwise approach toward creation of a principles oriented competency-based medical education curriculum for plastic surgery are presented. An assessment matrix designed to sample resident exposure to core principles and key procedures is proposed, along with suggestions for generating validity evidence for assessment tools. CONCLUSIONS: The ideal curriculum should provide exposure to core principles of plastic surgery while demonstrating competence through performance of index procedures that are most likely to benefit graduating residents when entering independent practice and span all domains of plastic surgery. The authors advocate that exploring the role and potential benefits of competency-based medical education in plastic surgery residency training is timely.

A systematic review of the effects of resident duty hour restrictions in surgery: impact on resident wellness, training, and patient outcomes.

BACKGROUND: In 2003, the Accreditation Council for Graduate Medical Education (ACGME) mandated 80-hour resident duty limits. In 2011 the ACGME mandated 16-hour duty maximums for PGY1 (post graduate year) residents. The stated goals were to improve patient safety, resident well-being, and education. A systematic review and meta-analysis were performed to evaluate the impact of resident duty hours (RDH) on clinical and educational outcomes in surgery. METHODS: A systematic review (1980-2013) was executed on CINAHL, Cochrane Database, Embase, Medline, and Scopus. Quality of articles was assessed using the GRADE guidelines. Sixteen-hour shifts and night float systems were analyzed separately. Articles that examined mortality data were combined in a random-effects meta-analysis to evaluate the impact of RDH on patient mortality. RESULTS: A total of 135 articles met the inclusion criteria. Among these, 42% (N = 57) were considered moderate-high quality. There was no overall improvement in patient outcomes as a result of RDH; however, some studies suggest increased complication rates in high-acuity patients. There was no improvement in education related to RDH restrictions, and performance on certification examinations has declined in some specialties. Survey studies revealed a perception of worsened education and patient safety. There were improvements in resident wellness after the 80-hour workweek, but there was little improvement or negative effects on wellness after 16-hour duty maximums were implemented. CONCLUSIONS: Recent RDH changes are not consistently associated with improvements in resident well-being, and have negative impacts on patient outcomes and performance on certification examinations. Greater flexibility to accommodate resident training needs is required. Further erosion of training time should be considered with great caution.

Cosmetic surgery training in Canadian plastic surgery residencies: are we training competent surgeons?

BACKGROUND: With the demand for cosmetic surgery continuing to rise, it is necessary to reevaluate the current state of cosmetic surgery training during plastic surgery residency. An evaluation of cosmetic surgery training in US plastic surgery residency programs in 2006 identified several areas for improvement, resulting in changes to both the duration and content of training. OBJECTIVES: The authors assess the current state of cosmetic surgery training in Canadian plastic surgery residency programs. METHODS: A paper survey of all graduating Canadian plastic surgery residents eligible to complete the 2009 Royal College of Physicians and Surgeons of Canada fellowship examinations was performed (N = 29). The survey was conducted primarily at the Canadian Plastic Surgery Review Course in February 2009, with surveys collected from absent residents by e-mail within 1 month after the course. The survey covered 2 broad areas: (1) specifics regarding resident cosmetic surgery training and (2) confidence and satisfaction associated with this experience. RESULTS: Of the 29 residents surveyed, 28 responded (96%). The majority of Canadian plastic surgery residency programs (75%) have a designated cosmetic surgery rotation, but 90% of respondents felt it has become increasingly difficult to gain exposure to cosmetic procedures as most are performed at private surgery centers. Elective rotations at cosmetic surgery practices and resident cosmetic clinics were considered the most beneficial for cosmetic surgery education. Residents considered cosmetic surgery procedures of the face (such as rhinoplasty and facelift) more challenging, but they had more confidence with breast and body contouring procedures. CONCLUSIONS: Canadian plastic surgery residency programs need to ensure that residents continue to receive comprehensive exposure to both surgical and nonsurgical cosmetic procedures to ensure our specialty's continued leadership in this evolving and highly competitive field. A multidimensional approach utilizing a variety of readily available resources will ensure that the current and future cosmetic surgery educational needs of Canadian plastic surgery residents are met.

Face lift.

LEARNING OBJECTIVES: After reading this article, the participant should be able to: 1. Identify and describe the anatomy of and changes to the aging face, including changes in bone mass and structure and changes to the skin, tissue, and muscles. 2. Assess each individual's unique anatomy before embarking on face-lift surgery and incorporate various surgical techniques, including fat grafting and other corrective procedures in addition to shifting existing fat to a higher position on the face, into discussions with patients. 3. Identify risk factors and potential complications in prospective patients. 4. Describe the benefits and risks of various techniques. SUMMARY: The ability to surgically rejuvenate the aging face has progressed in parallel with plastic surgeons' understanding of facial anatomy. In turn, a more clear explanation now exists for the visible changes seen in the aging face. This article and its associated video content review the current understanding of facial anatomy as it relates to facial aging. The standard face-lift techniques are explained and their various features, both good and bad, are reviewed. The objective is for surgeons to make a better aesthetic diagnosis before embarking on face-lift surgery, and to have the ability to use the appropriate technique depending on the clinical situation.

The modified lateral brow lift.

In the aging face, the lateral third of the brow ages first and ages most. Aesthetically, eyebrow shape is more significant than height and eyebrow shape is highly dependent on the level of the lateral brow complex. Surgical attempts to elevate the brow complex are usually successful medially, but often fail laterally. The "modified lateral brow lift" is a hybrid technique, incorporating features of an endoscopic brow lift (small hidden incisions, deep tissue fixation) and features of an open coronal brow lift (full thickness scalp excision). Sensory innervation of the scalp is preserved and secure fixation of the elevated lateral brow is achieved. Side effects and complications are minimal.
