RESUMO

UNLABELLED: There are many well-established methods for the reconstruction of the lower lip. The selection of a particular method generally relies on the amount of lip resected and the amount of lip remaining. In cases of large defects (>50% of the lip length) where direct closure and lip-switch techniques are inadequate, a perioral flap is used. All techniques for perioral flaps described until now result in an unwanted decrease in circumoral opening. The only available method that keeps the circumoral opening the same is a distant or regional free flap, and this technique is usually reserved for more extreme defects because it is more radical, technically demanding, and can pose a greater risk of complications. In this study, we describe a novel technique for reconstruction of the lower lip using a perioral flap in which the circumoral opening is kept the same. LEVEL OF EVIDENCE V: This journal requires that authors assign a level of evidence to each article.

RESUMO

Septorhinoplasty is associated with postoperative infection in less than 2% of cases, even without the use of prophylactic antibiotics. However, there is a concern that increasingly prevalent, highly virulent pathogens such as MRSA may predispose to postoperative infections. Over the past several decades, MRSA has emerged as the most important cause of antibiotic-resistant nosocomial infection. MRSA-associated infections related to nasal surgery are underreported in the literature. We present a case of MRSA-associated infection following a routine septorhinoplasty in a health care worker. We discuss the incidence of this complication and contributing risk factors. The classification of MRSA-associated infections into genotypically distinct hospital-acquired and community-acquired subtypes is reviewed, and the associated differences in epidemiology, clinical presentation, and antibiotic susceptibility are discussed. A comprehensive strategy incorporating diagnostic workup, preventative management based upon preoperative risk stratification, and treatment of MRSA-associated soft tissue infections is presented.

RESUMO

OBJECTIVE/HYPOTHESIS: To assess the use of a three-dimensional (3D) printed, multilayer facial flap model for use in trainee education as an alternative method of teaching surgical techniques of facial reconstruction. STUDY DESIGN: Cohort study. METHODS: A 3D printed facial flap simulator was designed from a computed tomography scan and manufactured out of silicone for low-cost, high-fidelity simulation. This simulator was tested by a group of Otolaryngology-Head and Neck Surgery trainees at a single institution. The simulator group was compared to a control group who completed an exercise on a traditional paper facial flap exercise. Both groups underwent didactic lectures prior to completing their respective exercises. Pre- and post-exercise Likert scale surveys measuring experience, understanding, effectiveness, and realism were completed by both groups. Central tendency, variability, and confidence intervals were measured to evaluate the outcomes. RESULTS: Trainees completing the facial flap simulator reported a statistically significant (p < 0.05) improvement in overall expertise in facial flap procedures, design of facial flaps, and excision of standing cutaneous deformities. No statistically significant improvement was seen in the control group. CONCLUSIONS: Trainees found the facial flap simulator to be an effective and useful training tool with a high level of realism in surgical education of facial reconstruction. Surgical simulators can serve as an adjunct to trainee education, especially during extraordinary times such as the novel coronavirus disease 2019 pandemic, which significantly impacted surgical training.

RESUMO

Nasal reconstructive techniques have advanced significantly over the past 50 years. Modern techniques in nasal reconstruction are based on the nasal aesthetic subunits. In order to achieve ideal outcomes, reconstructive surgeons must consider differences in tissue qualities across the nasal aesthetic subunits and formulate reconstructive plans based on these differences. Local flaps, skin grafts, and several types of interpolated flaps comprise the most commonly used techniques for nasal reconstruction. Defects that involve structural or internal lining defects require reconstruction of significantly higher complexity.

RESUMO

OBJECTIVE: To evaluate the long-term effectiveness of, and the complications associated with, carbon dioxide laser treatment of rhytidosis and solar aging. METHODS: This retrospective report describes our experience with 47 patients who underwent entire facial carbon dioxide laser resurfacing. RESULTS: The mean improvement in facial rhytid score at long-term follow-up was 45%. This improvement was consistent in all facial subsites. With the exception of 1 case of hyperpigmentation, which resolved within 2 years of treatment, hypopigmentation was the only long-term adverse effect. This complication was present in 6 patients (13%). The patients who developed hypopigmentation were more likely to have a greater response to treatment. CONCLUSION: Our findings show that carbon dioxide laser resurfacing is a safe and effective treatment for facial rhytids.

RESUMO

Importance: Melanoma arising in chronically photodamaged skin, especially on the head and neck, is often characterized by poorly defined clinical margins and unpredictable occult extension. Staged excision techniques have been described to treat these challenging melanomas. Objective: To investigate the local recurrence rates and margin to clearance end points using staged excision with comprehensive hematoxylin-eosin-stained permanent section margin control. Design, Setting, and Participants: In this observational cohort study performed from October 8, 1997, to December 31, 2006, with a median follow-up of 9.3 years, 806 patients with melanoma on the head and neck, where clinical occult extension is common, were studied at an academic medical center. Interventions: Staged excision with comprehensive hematoxylin-eosin-stained permanent section margin control commonly known as the square technique. Main Outcomes and Measures: Local recurrence rates and margin to clearance end points. Results: A total of 806 patients (276 women [34.2%]; 805 white [99.9%]) with a median age at the time of first staged excision procedure of 65 years (range, 20-94 years) participated in the study. The estimated local recurrence rates were 1.4% at 5 years, 1.8% at 7.5 years, and 2.2% at 10 years. For each 50-mm2 increase in the size of the clinical lesion, there was a 9% increase in the rate of local recurrence (hazard ratio, 1.09; 95% CI, 1.02-1.15; P = .02). The mean (SD) margin from lesion to clearance for melanoma in situ was 9.3 (5.1) mm compared with 13.7 (5.9) mm for invasive melanoma. For melanoma in situ, margins were clear after 5 mm or less in 232 excisions (41.1%) and after 10 mm or less in 420 excisions (74.5%). For invasive melanoma, margins were clear after 5 mm or less in 8 excisions (3.0%) and after 10 mm or less in 141 excisions (52.2%). Conclusions and Relevance: Staged excision with comprehensive permanent section margin control of melanomas arising in chronically sun-damaged skin on the head and neck has favorable recurrence rates when melanoma margins are difficult to assess, and recurrence rates are high with traditional techniques.

RESUMO

IMPORTANCE: Whether undergoing cervicofacial rhytidectomy after radiotherapy for tumors of the head and neck is associated with increased complication rates and therefore should be avoided remains unknown. OBJECTIVE: To evaluate complication rates in patients who have undergone cervicofacial rhytidectomy after radiotherapy for head and neck tumors and compare these rates with those of patients who have not undergone radiotherapy. DESIGN, SETTING, AND PARTICIPANTS: Retrospective review of the medical records of 16 patients who underwent cervicofacial rhytidectomy after completing radiotherapy for head and neck tumors and those of 16 age-matched control participants who did not undergo radiotherapy. Patients underwent treatment from July 1, 2006, through February 28, 2014, with final follow-up on February 28, 2014. Complications after surgery were reviewed and data for surgery type, technique, radiation dose and delivery method, and time to surgery after radiotherapy were analyzed. Data were collected from June 1 through December 31, 2013, and analyzed from January 1, 2014, through June 1, 2015. MAIN OUTCOMES AND MEASURES: Rate of complications after surgery. RESULTS: The radiotherapy and control group patients were a mean of 62 years old. In the radiotherapy group, 8 of 16 were women; 14 of 16 were women in the control group. Two major complications, 1 hematoma and 1 perioperative stroke, occurred in the 16 patients who composed the study cohort. In the control group, there was 1 case of transient facial nerve weakness and 1 case of cellulitis that was successfully treated with antibiotics. Two patients experienced wound dehiscence, and no incidents of motor or sensory nerve injury occurred. Subcutaneous face-lift (3 of 3 patients [100%] vs 1 of 13 patients [8%] who underwent superficial musculoaponeurotic system and deep-plane face-lifts; P = .02) and the addition of chemotherapy (4 of 9 patients [44%] vs 0 of 7 patients who did not receive chemotherapy; P = .04) were associated with increased complications. Being older and the time from completion of radiotherapy and surgery did not show any correlation to complications. CONCLUSIONS AND RELEVANCE: Aesthetic facial surgery after radiotherapy has an increased risk for complication compared with facial surgery without radiotherapy. The incidence of wound dehiscence is elevated in the population undergoing radiotherapy but can be managed conservatively in most cases. Patients who undergo radiotherapy must be counseled on the increased risk for complications before proceeding with cervicofacial rhytidectomy. LEVEL OF EVIDENCE: 3.

RESUMO

OBJECTIVE: To obviate the difficulty of ruling out confounding variables (eg, age, individual variability) as the source of differences seen when comparing tumor tissue and control tissue from unrelated individuals, we examined the expression of matrix metalloproteinase (MMP)-1 (interstitial collagenase) and MMP-9 (92-kDa gelatinase B) in histologically normal skin immediately adjacent to basal cell carcinomas (peritumoral tissue) after Mohs micrographic surgery and postauricular skin from the same patients. DESIGN: Peritumoral and postauricular skin samples were obtained from 17 patients undergoing Mohs surgery. Expression of MMP-1 and MMP-9 was examined in these specimens using a combination of approaches including zymography, collagen-degradation assays, and immunohistology. RESULTS: The expression levels of MMP-1 and MMP-9 were consistently elevated in the peritumoral tissue compared with skin from the distal site. CONCLUSION: This finding indicates that even when potentially important variables such as age and individual variability are controlled for, tumor-specific effects on the expression of MMP-9 and MMP-1 remain.

RESUMO

Complications after rhytidectomy can be distressing for the patient and surgeon. Although meticulous surgical technique and a complete understanding of the causes of adverse outcomes can minimize the risk for severe complications, an open and honest rapport with the patient when complications do occur is essential for effective management. This article discusses the likely etiologies of face-lift complications, techniques to prevent them, and helpful treatments when complications occur.

RESUMO

Fat preservation lower lid blepharoplasty is the authors' preferred technique for surgical rejuvenation of the aging lower lid. Key technical refinements are overlaid on a conceptual framework developed over the past 2 decades by several investigators. The use of the orbicularis oculi muscle suspension flap is a useful adjunct to the transcutaneous approach to lower lid blepharoplasty.

RESUMO

IMPORTANCE: The decision whether to discontinue antiplatelet and/or anticoagulant medications before a facial plastic surgical procedure is a complicated and multifactorial process that involves weighing the risk of perioperative thromboembolic complications with bleeding-related complications. OBJECTIVE: To determine the complication rates in patients who undergo a range of facial plastic surgical procedures while receiving antiplatelet and/or anticoagulation therapy. DESIGN, SETTING, AND PARTICIPANTS: A total of 9204 surgical procedures from January 1, 2007, through December 31, 2012, at an academic medical center and its affiliated surgical sites were analyzed, with patients who continued receiving antiplatelet and/or anticoagulation (aspirin, clopidogrel bisulphate, and warfarin sodium) therapy during the perioperative period identified and compared with a matched case-control group of patients who did not receive antiplatelet and/or anticoagulation therapy during this period. INTERVENTIONS: Facial plastic surgery procedures and perioperative management. MAIN OUTCOME AND MEASURES: Complication rates of wound healing (dehiscence or necrosis), infection, bleeding (hematoma or ecchymosis), and return to the operating room. RESULTS: Patients who received aspirin therapy at the time of surgery were not more likely to have a complication compared with control patients (odds ratio [95% CI], 0.73 [0.45-1.17]). Patients who received warfarin had increased perioperative bleeding (odds ratio [95% CI], 3.80 [1.15-12.60]) and postoperative infections (odds ratio [95% CI], 7.29 [1.17-45.40]) compared with control patients. Serious complications (flap necrosis, dehiscence, or return to the operating room) were not increased with warfarin use. CONCLUSIONS AND RELEVANCE: This study demonstrates that patients who undergo facial plastic surgery may continue taking antiplatelet and/or anticoagulation therapy during the perioperative period safely with minimal serious complications. LEVEL OF EVIDENCE: 3.

RESUMO

There have been many important contributions to the literature on the subject of facial rejuvenation surgery. There has been a trend toward less invasive techniques that offer patients shorter recovery periods with levels of aesthetic satisfaction comparable to those of more invasive and complex procedures. Techniques reviewed in this article include midface suture meloplication, and purse-string suture suspension of the superficial musculoaponeurotic system to effect changes in the lower one third of the face. Another exciting area is the use of fibrin sealants and autologous platelet gels to enhance the adhesion of the tissue flaps at closure and reduce the amount of ecchymosis and edema in the recovery period. Their ability to decrease bruising, swelling, and lessen the frequency of complications has the potential of increasing patient satisfaction through a quicker return to normal activities.

RESUMO

The literature is replete with discussions outlining surgical techniques for managing nasal tip deformities. In contrast, articles devoted to specific dorsal nasal abnormalities are rare. Surgical management of the nasal dorsum has traditionally been relegated to either augmentation or reduction followed by osteotomy. Contemporary rhinoplasty demands attention to the creation of an ideal profile line, which may require dorsal reduction in some areas and augmentation in others. Treatment of the patient with an appropriate projection of the profile but with a wide nasal dorsum presents a special challenge: to narrow the nasal bridge without altering its projection. We discuss several surgical techniques to narrow the nasal dorsum, while maintaining dorsal height. Selected cases are presented to illustrate these techniques and to clarify surgical options.

RESUMO

OBJECTIVES: To describe our technique of using septal bone grafts for correction and stabilization of caudal septal deviation and to evaluate the effectiveness of this technique in the treatment of the deviated caudal septum. METHODS: A retrospective review of 81 patients who underwent open septorhinoplasty using septal bone grafts for correction of a caudal septal deviation or deformity and nasal obstruction. We reviewed medical records to determine postoperative outcomes in nasal obstruction and caudal septal position. RESULTS: Of the 81 patients, we included 66 with adequate follow-up information in the analysis. Follow-up duration ranged from 1 to 72 (mean, 8) months. Postoperative examination revealed a midline septum in 55 of the 66 patients (83%). Fifty-seven patients (86%) reported resolution of nasal obstruction; 49 (74%) had a midline septum and resolved nasal obstruction at the longest follow-up. Nine patients (14%) reported postoperative nasal obstruction, of whom only 3 required revision surgery. CONCLUSION: Nasal septal bone grafts can be an effective tool in stabilizing severe cartilaginous deformities or deviations and correcting caudal septal deviation.

RESUMO

IMPORTANCE: The reconstruction of cutaneous defects of the cheek and lip is a foundational topic for facial plastic and reconstructive surgeons. Facial defects have a significant impact on patient quality of life that has been well demonstrated. OBJECTIVE: To review new findings that have an impact on the planning and understanding of local flaps for the reconstruction of cutaneous defects of the cheek and upper lip; recent research in facial soft-tissue anatomy and vascular anatomy is integrated into a discussion of local flap reconstruction. EVIDENCE REVIEW: A Medline search of scientific literature was conducted, with an emphasis on 1980 to the present. Search terms included cheek; lip; reconstruction; vascular anatomy, soft-tissue anatomy, aging face, outcomes, and perforator flap. Cadaveric studies were specifically sought for anatomic review, and comparison group outcome studies are preferentially cited over clinical case series. FINDINGS: Reconstruction of large medial defects of the cheek and upper lip is particularly challenging, and the V-Y subcutaneous tissue pedicle island advancement flap is valuable for repair of these defects. Outcomes analyses for local flap reconstruction are in high demand. Pedicled perforator flaps will likely see increased application for facial reconstruction in the near future. CONCLUSION AND RELEVANCE: Detailed knowledge of the soft-tissue anatomy of the cheek and lip is critical to accurate surgical planning in local flap reconstruction.

RESUMO

Traditional upper blepharoplasty typically involves resection of excess upper eyelid skin and muscle with or without fat excision. Well-established concepts in periorbital aging have been challenged by newer morphologic and histologic studies that have characterized the changes that occur in the various periorbital soft tissue components. Several modified or adjunctive techniques have recently emerged to improve esthetic outcomes in upper blepharoplasty. The authors review surgical technique in detail: nasal fat repositioning, orbicularis oculi preservation, increasing lateral upper eyelid fullness, lacrimal gland resuspension, internal brow elevation, and glabellar myectomy, along with complications and aftercare involved with procedures.

RESUMO

OBJECTIVE: To evaluate the aesthetic and functional outcomes of a full-thickness skin graft and a separately harvested auricular cartilage graft for nasal alar defects created by Mohs micrographic surgery. DESIGN: Twenty patients with deep Mohs micrographic surgery defects of the nasal ala who underwent reconstruction with a full-thickness skin graft and an auricular cartilage graft were prospectively studied at a single tertiary care institution between 2010 and 2011 in a nonrandomized, nonblinded study. An ordinal 5-point Likert scale evaluation of overall outcomes was performed by 4 independent surgeon raters. RESULTS: The mean outcome for use of the full-thickness skin and auricular cartilage graft construct was a score of 2.3 on a scale of 1 through 5, with 1 being excellent and 5 being poor. The mean duration of follow-up was 6 months, with a range of 5 weeks to 23 months. There were no clinically meaningful losses of constructs in the patients studied. CONCLUSION: A full-thickness skin graft and a separately harvested auricular cartilage graft are valuable and reliable tools for reconstructing deep nasal alar defects that require support to prevent alar retraction or collapse, particularly when a single-stage procedure is preferred or necessary because of medical comorbidities.

RESUMO

IMPORTANCE: Understanding age-related changes is important when considering cartilage-based implants or grafts during rhinoplasty and nasal reconstructive surgery. OBJECTIVE: To characterize the cellular and architectural changes in human nasal cartilage with aging. DESIGN: Laboratory study. PARTICIPANTS: Nasal septal cartilage was harvested from 50 consecutive patients undergoing septoplasty, rhinoplasty, or septorhinoplasty. INTERVENTION: Cartilage specimens were stained with hematoxylin-eosin (H&E) and safranin O for cartilage. MAIN OUTCOME MEASURES: A modified Mankin histologic grading scale was used to analyze each cartilage sample for H&E findings and safranin O staining. Higher H&E scores indicated more degenerative changes, while higher safranin O scores indicated reductions in proteoglycan content within the cartilage matrix, representing decreased active chondrocyte activity. Correlation between H&E and safranin O scores and patient age was determined. RESULTS: There was positive correlation between safranin O staining scores and age, with higher scores seen with advancing age (P = .01). A linear regression best-fit equation was determined to calculate a potential safranin O staining score for a given age. CONCLUSIONS AND RELEVANCE: We have quantitatively determined that advancing age is positively correlated with reductions in cartilage proteoglycan content and active cartilage growth. This finding not only enhances our current understanding of the natural changes that occur in cartilage with aging but may also affect surgical decision making when cartilage grafting is considered during functional, reconstructive, and aesthetic rhinoplasty. LEVEL OF EVIDENCE: NR.

RESUMO

Numerous methods have been used for dorsal augmentation in reconstructive and aesthetic rhinoplasty. The Tasman technique is a method for dorsal augmentation using diced cartilage solidified by tissue sealant. This article describes the author's early experience using the Tasman technique and offers some helpful suggestions to surgeons who might wish to use this unique method of preparing a cartilaginous graft.
