Patient-Reported Outcomes Measures in Rhinoplasty: Need for Use and Implementation.

Patient-reported outcome metrics (PROMs) are increasingly utilized to capture data about patients' quality of life. PROMs play an important role in the value-based health care movement by providing a patient-centered metric of quality. There are many barriers to the implementation of PROMs, and widespread adoption requires buy-in from numerous stakeholders including patients, clinicians, institutions, and payers. Several validated PROMs have been utilized by facial plastic surgeons to measure both functional and aesthetic outcomes among rhinoplasty patients. These PROMs can help clinicians and rhinoplasty patients participate in shared decision making (SDM), a process via which clinicians and patients arrive at treatment decisions together through a patient-centered approach. However, widespread adoption of PROMs and SDM has not yet been achieved. Further work should focus on overcoming barriers to implementation and engaging key stakeholders to increase the utilization of PROMs in rhinoplasty.

Reconstruction of the Intranasal Lining.

Reconstruction of full-thickness nasal defects has been the subject of surgical inquiry and innovation for over 2,000 years. The replacement of the internal nasal lining is a critical feature of complex nasal reconstruction. Successful reconstruction can prevent cicatricial contraction, external distortion, and internal stenosis. An array of reconstructive possibilities has been described, including cutaneous, mucosal, and fascial options. The challenge to the reconstructive surgeon is to select the repair that maximizes internal stability, while maintaining a patent nasal airway, minimizing morbidity, and meeting patient expectations. This article reviews the options available for the reconstruction of the intranasal lining.

Titanium Mesh Nasal Repair without Nasal Lining.

The objective of this study was to describe outcomes for patients who underwent titanium mesh reconstruction of full-thickness nasal defects without internal lining repair. This is a retrospective cohort study. Patients with through-and-through nasal defects were identified at a single academic institution between 2008 and 2016. Nasal reconstruction was performed with either titanium mesh and external skin reconstruction without repair of the intranasal lining or traditional three-layer closure. Five patients underwent titanium mesh reconstruction and 11 underwent traditional three-layer repair. Median follow-up was 11 months (range, 2-66 months). The only significant difference between groups was older age in patients undergoing titanium reconstruction (mean, 81 vs. 63 years; difference of 18; 95% confidence interval [CI], 4-32 years). Defect extent including overall size and structures removed was similar between groups (p > 0.05). Paramedian forehead flap was the most common external reconstruction in both groups (100% for titanium mesh and 73% for three-layer closure). Time under anesthesia was significantly shorter for titanium mesh reconstruction (median, 119 vs. 314 minutes; difference of 195; 95% CI, 45-237). Estimated blood loss and length of hospital stay were similar between groups (p > 0.05). Complication rates were substantial although not significantly different, 40 and 36% in titanium and three-layer reconstruction, respectively (p > 0.05). All patients with complications after titanium reconstruction had prior or postoperative radiotherapy. Titanium mesh reconstruction of through-and-through nasal defects can successfully be performed without reconstruction of the intranasal lining, significantly decreasing operative times. This reconstructive technique may not be suitable for patients who undergo radiotherapy.

Outcomes and complications of endoscopic approaches for malignancies of the paranasal sinuses and anterior skull base.

OBJECTIVES: Malignant tumors of the paranasal sinuses are traditionally approached by a variety of external incisions. Recent advances in endoscopic endonasal surgery have allowed for some of these tumors to be treated endoscopically. The purpose of this study was to assess the outcomes and complications of the endoscopic approach in a series of patients with paranasal sinus malignancies. METHODS: A retrospective chart review was performed of patients with sinonasal or skull base malignancies treated with endoscopic or endoscopic-assisted resections at a tertiary care institution from 2002 to 2010. Patient data were collected on symptoms, tumor type, operative technique, and postoperative course. Baseline risk factors, overall and disease-free survival data, and surgical outcomes were compared between the two groups. RESULTS: Of the total 49 patients, 36 (73%) underwent an endoscopic approach and 13 (27%) underwent endoscopic-assisted approaches. Sarcomas (9 cases) were the most common tumor type, followed by squamous cell carcinoma (8), adenocarcinoma (8), and melanoma (7). The mean follow-up time for all patients was 3.58 years (range, 1.1 to 8.8 years). Surgical complications were more frequent with open approaches than with endoscopic approaches (23.1% versus 5.6%; p = 0.11). Medical complications were significantly more common with open approaches (38.5% versus 8.3%; p = 0.02). The disease-specific mortality rate was 8% (4 of 49). The local tumor recurrence rate was 16% (8 of 49). The 3-year disease-free survival rates were 86.8% in the endoscopic group and 67.7% in the open group (p = 0.047); however, the patients in the endoscopic group had lower T stages (p = 0.0068) and lower ASA scores (p = 0.03). CONCLUSIONS: Endoscopic approaches to the sinuses and skull base have become progressively more sophisticated with advances in skull base reconstruction, advances in surgical technique, and improvements in technology. This study demonstrates the relative safety and utility of the endoscopic approach for sinonasal and skull base malignancies. In carefully selected patients, endoscopic approaches demonstrate survival rates comparable to those of traditional surgery, and fewer perioperative complications. With appropriate planning and careful surgical decision-making, endoscopic surgery shows promise as a minimally invasive alternative in the treatment of sinonasal malignancies.

Mastering Midface Injections.

Injectable filler is one of the most common cosmetic procedures performed annually. An aging face shows a characteristic loss of volume in the deep fat pads of the midface. The goal of midfacial rejuvenation with injectable filler is to restore lost volume, with the suborbicularis fat pad and deep medial cheek fat being the most critical areas. Filler can be instilled here with a cannula or needle with successful outcomes. However, this procedure is not without complications if proper technique and underlying anatomy are not respected.

A Contemporary Review of the Role of Facial Prostheses in Complex Facial Reconstruction.

BACKGROUND: Maxillofacial prostheses provide effective rehabilitation of complex facial defects as alternatives to surgical reconstruction. Although facial prostheses provide aesthetically pleasing reconstructions, multiple barriers exist that prevent their routine clinical use. The accessibility of facial prostheses is limited by the scarce supply of maxillofacial prosthodontists, significant time commitment and number of clinic appointments required of patients during prosthesis fabrication, short lifespan of prostheses, and limited outcomes data. METHODS: A literature review was completed using PubMed and Embase databases, with search phrases including face and maxillofacial prostheses. Patient cases are included to illustrate the use of facial prostheses to reconstruct complex facial defects. RESULTS: The clinical use of facial prostheses requires a multidisciplinary team including a reconstructive surgeon, a maxillofacial prosthodontist, and an anaplastologist, if available, to provide patients with aesthetically appropriate facial prostheses. Developing technology including computer-aided design and three-dimensional printing may improve the availability of facial prostheses by eliminating multiple steps during prosthesis fabrication, ultimately decreasing the time required to fabricate a prosthesis. In addition, enhanced materials may improve prosthesis durability. Long-term outcomes data using validated measures is needed to support the continued use of facial prostheses. CONCLUSIONS: Facial prostheses can be used to reconstruct complex facial defects, and bone-anchored prostheses are associated with high patient satisfaction. Multiple barriers prevent prostheses from being used for facial reconstruction. New technologies to assist the design and fabrication of prostheses, and cost reduction measures, may allow their use in the appropriately selected patient.

The use of race-based terminology in the rhinoplasty literature.

PURPOSE OF REVIEW: To provide an overview of the use of race-based terminology in the rhinoplasty literature. RECENT FINDINGS: The rhinoplasty literature is often indexed by race, with common usage of the terms Ethnic/Non-Caucasian/Nonwhite; African American/of African descent; Hispanic/Latinx; and Asian to refer to certain patient populations. There are wide variations in facial features within these populations, but specific traits may be more prevalent in patients with certain backgrounds. More recently, in particular within the 'Asian rhinoplasty' literature, titles have pivoted to include specific anatomic characteristics of interest, which offers a more objective way of discussing this topic. SUMMARY: The use of race and ethnicity to describe facial and nasal anatomy in the rhinoplasty literature introduces subjectivity and diminishes the validity of the rhinoplasty literature. We advocate the usage of specific physical and anatomic descriptions rather than race and ethnicity within the rhinoplasty literature.

Nasal Septal Perforation Repair with an Inferior Turbinate Flap and Acellular Dermal Matrix.

Nasal septal perforation is an uncommon disorder that can cause disturbance of nasal physiology. The perforations can vary widely in size, location, and symptomatology. Many different closure techniques have been described in the literature; however, no gold standard has been recognized. The choice of surgical technique usually depends on the characteristics of the perforation and surgeon experience. Due to the goal of perforation repair being restoration of normal nasal physiology, techniques with the best outcomes have been those resurfacing the septum with nasal respiratory mucosa. Here we present our novel surgical method for large (> 2 cm) septal perforation closure using a modification of the inferior turbinate flap repair using a polydioxanone plate and the acellular dermal matrix allograft (Alloderm, Allergan Inc.).

Effectiveness of Prophylactic Preoperative Antibiotics in Mandible Fracture Repair: A National Database Study.

OBJECTIVE: This is the first database study to assess the effectiveness of prophylactic preoperative antibiotics (PPAs) in mandible fracture repair. STUDY DESIGN: Retrospective cohort. SETTING: Database study using US inpatient and outpatient insurance claims submitted from July 2006 to March 2015. METHODS: The IBM MarketScan Commercial Database was queried for adults aged 18 to 64 years who had undergone first-time mandible fracture repair according to Current Procedural Terminology codes for open and closed repair. Primary outcomes included surgical revision, local infection, and osteomyelitis. Rates were compared between cohorts based on whether or not patients had filled antibiotic prescriptions during the preoperative period alone. The effects of drug abuse and type of mandible repair (open vs closed) were explored. Multivariate Poisson regression models were used to calculate adjusted relative risk estimates, and 95% CIs were used to determine statistically significant differences. RESULTS: A total of 2676 patients were included, with 847 (31.7%) filling PPAs and 1829 (68.3%) filling no antibiotics. Rates were 38.9% for revision, 5.8% for local infection, and 2.1% for osteomyelitis. After multivariate analysis, exposure to PPAs was not associated with surgical revision (adjusted relative risk, 1.04; 95% CI, 0.94-1.15), local infection (1.16; 0.82-1.64), or osteomyelitis (1.21; 0.68-2.14). Patients were more likely to fill PPAs if they underwent open repair (35.3%) versus closed (26.6%) (proportion difference, 8.7%; 95% CI, 5.2%-12.2%), but exposure to antibiotics did not predict outcomes on subgroup analysis. CONCLUSION: PPAs do not improve mandible repair outcomes, regardless of repair type.

Patients' Views of Shared Decision-making and Decisional Conflict in Otolaryngologic Surgery During the COVID-19 Pandemic.

Importance: A patient's decision to undergo surgery may be fraught with uncertainty and decisional conflict. The unpredictable nature of the COVID-19 pandemic warrants further study into factors associated with patient decision-making. Objective: To assess decisional conflict and patient-specific concerns for people undergoing otolaryngologic surgery during the pandemic. Design, Setting, Participants: This prospective cross-sectional survey study was conducted via telephone from April 22 to August 31, 2020. English-speaking adults scheduled for surgery from a single academic surgical center were invited to participate. Individuals who were non-English speaking, lacked autonomous medical decision-making capacity, scheduled for emergent surgery, or had a communication disability were excluded. For race and ethnicity reporting, participants were classified dichotomously as White according to the Behavioral Risk Factor Surveillance System from the Centers for Disease Control and Prevention or non-White as a collective term including Black or African American, American Indian or Alaska Native, Asian, or Pacific Islander race and ethnicity. Exposures: The SURE Questionnaire (sure of myself, understand information, risks/benefits ratio, and encouragement) was used to screen for decisional conflict, with a total score greater than or equal to 3 indicating clinically significant decisional conflict. Participants were asked to share their specific concerns about having surgery. Main Outcome and Measures: Decisional conflict and patient demographic data were assessed via bivariate analyses, multivariable logistic regression and conjunctive consolidation. Patient-specific concerns were qualitatively analyzed for summative themes. Results: Of 444 patients screened for eligibility, 182 (40.9%) respondents participated. The median age was 60.5 years (interquartile range, 48-70 years). The racial and ethnic identity of the participants was classified as binary White (84% [153 of 182]) and non-White (16% [29 of 182]). The overall prevalence of decisional conflict was 19% (34 of 182). Decisional conflict was more prevalent among non-White than White participants (proportion difference 18.8%, 95% CI, 0.6%-37.0% and adjusted odds ratio 3.0; 95% CI, 1.2-7.4). Combining information from multiple variables through conjunctive consolidation, the group with the highest rate of decisional conflict was non-White patients with no college education receiving urgent surgery (odds ratio, 10.8; 95% CI, 2.6-45.0). Intraoperative and postoperative concerns were the most common themes expressed by participants. There was a clinically significant difference in the proportion of participants who screened positive for decisional conflict (30%) and expressed postoperative concerns than those who screened negative for decisional conflict (17%) (proportion difference, 13%; 95% CI, 1%-25%). Among patients reporting concerns about COVID-19, most screened positive for decisional conflict. Conclusions and Relevance: Results of this cross-sectional survey study suggest that the COVID-19 pandemic was associated with decisional conflict in patients undergoing otolaryngologic surgery. Consistent discussion of risks and benefits is essential. The role of race and ethnicity in decisional conflict warrants further study.

Powering the Gracilis for Facial Reanimation: A Systematic Review and Meta-analysis of Outcomes Based on Donor Nerve.

Importance: Free gracilis transfer for dynamic reanimation in chronic facial paralysis is the gold standard, but there remains a need to better understand outcomes with respect to the donor nerve. Objective: To characterize outcomes in adults undergoing primary gracilis transfer for facial paralysis stratified by donor nerve used for neurotization. Data Sources: Search strategies were used in Ovid MEDLINE (1946-2019), Embase (1947-2019), Scopus (1823-2019), Cochrane Central Register of Controlled Trials (CENTRAL), and ClinicalTrials.gov (1997-2019). Study Selection: Inclusion and exclusion criteria were designed to capture studies in adults with unilateral chronic facial paralysis undergoing single-paddle free gracilis transfer. All study types were included except case reports. Abstracts and full texts were reviewed in duplicate. Of 130 unique citations, 10 studies including 295 patients were included after applying inclusion and exclusion criteria. Data were analyzed between November 2018 and December 2019. Data Extraction and Synthesis: PRISMA guidelines were followed. The Newcastle-Ottawa scale was used to assess study quality, and the Cochrane Risk of Bias tool was used to assess risk of bias. Independent extraction by 2 authors (P.M.V. and J.J.C.) was performed. Data were pooled using a random-effects model. Main Outcomes and Measures: Owing to heterogeneity in reporting of facial reanimation outcomes, we first performed a systematic review, and then compiled available outcomes for meta-analysis. Outcomes studied for meta-analysis were oral commissure excursion and facial symmetry. Results: Meta-analysis of masseteric nerve (MN) (n = 56) vs cross-facial nerve graft (CFNG) (n = 52) in 3 retrospective studies showed no statistical heterogeneity between these studies (I2 = 0%), and the standardized mean difference (SMD) was greater for MN (0.55; 95% CI, 0.17 to 0.94). Meta-analysis of angles of symmetry in 2 retrospective studies comparing MN (n = 51) to CFNG (n = 47) both at rest (-0.22; 95% CI, -0.63 to 0.18) and with smiling (-0.14; 95% CI, -0.73 to 0.46) were better with MN, though the difference was not statistically significant. Conclusions and Relevance: Owing to heterogeneity in reported outcomes from facial reanimation, we were unable to make definitive conclusions regarding the optimal donor nerve. Establishing a reporting standard at peer-reviewed journals to improve results reporting is one method to allow for improved collaboration in the future. Standardizing follow-up times, assessing spontaneity in an objective and reproducible fashion, and use of consistent outcome measures would allow for future meta-analyses and better understanding of options for facial reanimation.

Physical Therapy for Iatrogenic Facial Paralysis: A Systematic Review.

Importance: Facial paralysis (FP) after surgery has substantial functional, emotional, and financial consequences. Most iatrogenic FP is managed by watchful waiting, with the expectation of facial function recovery. A potential treatment is physical therapy (PT). Objective: To investigate whether noninvasive PT compared with no PT or other intervention improves facial nerve outcomes in adults with iatrogenic FP. Evidence Review: Patients with noniatrogenic FP, facial reanimation surgery, and invasive adjunctive treatments (acupuncture or botulinum toxin injection) were excluded. A systematic review was conducted for records discussing iatrogenic FP and PT; a search for these records was performed using Ovid MEDLINE (1946-2019), Embase (1947-2019), Scopus (1823-2019), Cochrane Database of Systematic Reviews, Cochrane Central Register of Controlled Trials, World Health Organization International Clinical Trials Registry Platform (2004-2019), and ClinicalTrials.gov (1997-2019). The references of all the included articles were also assessed for eligible studies. All human participant, English-language study designs with at least 2 cases were included. Quality assessment was performed using the Methodological Index for Non-randomized Studies (MINORS) and the revised Cochrane Risk of Bias 2 (RoB 2) tool for randomized controlled trials. All search strategies were completed on May 16, 2019, and again on October 1, 2019. Findings: Fifteen studies (7 of which were retrospective cohort studies) and 313 patients with iatrogenic FP were included in the systematic review. Most iatrogenic FP (166 patients [53%]) was associated with parotidectomy; traditional PT (ie, facial massage) was the most common intervention (196 patients [63%]). The use of various facial grading systems and inconsistent reporting of outcomes prevented direct comparison of PT types. Conclusions and Relevance: Because of heterogeneity in reported outcomes of facial nerve recovery, definitive conclusions were unable to be made regarding the association between PT and outcomes of iatrogenic FP. Physical therapy probably has benefit and is associated with no harm in patients with iatrogenic FP.

Algorithm for Management of Mandibular Condylar Base Fractures.

BACKGROUND: Increasing evidence suggests that open reduction and internal fixation of condylar base fractures in adults results in improved outcomes in regard to interincisal opening, jaw movement, pain, and malocclusion. However, most of the condylar fractures are managed by maxillomandibular fixation alone due to the need for specialized training and equipment. Our aim was to present an algorithm for condylar base fractures to simplify surgical management. METHODS: A retrospective review was performed of patients (n = 22) with condylar base fractures treated from 2016 to 2020. Patients who presented with operative fractures that require open treatment underwent 1 of 2 different techniques depending on the fracture type: a preauricular approach with a transoral approach if the condyle was dislocated (n = 2) or a transoral only approach (n = 20) in nondislocated cases. Operative time, occlusion, range of motion, and postoperative complications were assessed. RESULTS: Condylar base fractures were combined with other mandibular fractures in 16 of 22 patients. Patients with condylar dislocation were managed with a preauricular approach with a secondary transoral incision (n = 2, median 147 minutes). Those without dislocation were treated with a transoral approach (n = 20, median 159 minutes). Most patients were restored to their preoperative occlusion without long-term complications. CONCLUSIONS: We present a simplified algorithm for treating condylar base fractures. Our case series suggests that reduction in operative time and clinical success can be achieved with open reduction and internal fixation using a transoral approach alone or in combination with a preauricular approach for dislocated fractures.

Comparison of Autologous vs Homologous Costal Cartilage Grafts in Dorsal Augmentation Rhinoplasty: A Systematic Review and Meta-analysis.

Importance: Augmentation rhinoplasty requires adding cartilage to provide enhanced support to the structure of the nose. Autologous costal cartilage and irradiated homologous costal cartilage (IHCC) are well-accepted rhinoplasty options. Tutoplast is another alternative cartilage source. No studies, to our knowledge, have definitively demonstrated a higher rate of complications with IHCC grafts compared with autologous costal cartilage grafts. Objective: To compare rates of outcomes in the published literature for patients undergoing septorhinoplasty with autologous costal cartilage vs IHCC grafts vs Tutoplast grafts. Data Sources: For this systematic review and meta-analysis, the MEDLINE, Embase, Scopus, Cochrane Central Register of Controlled Trials, and ClinicalTrials.gov databases were searched for articles published from database inception to February 2019 using the following keywords: septorhinoplasty, rhinoplasty, autologous costal cartilage graft, cadaveric cartilage graft, and rib graft. Study Selection: Abstracts and full texts were reviewed in duplicate, and disagreements were resolved by consensus. Only patients who underwent an en bloc dorsal onlay graft were included for comparison to ensure a homogenous study sample. A total of 1308 results were found. After duplicate records were removed, 576 unique citations remained. Studies were published worldwide between January 1, 1990, and December 31, 2017. Data Extraction and Synthesis: Independent extraction by 2 authors was performed. Data were pooled using a random-effects model. Main Outcomes and Measures: All reported outcomes after septorhinoplasty and rates of graft warping, resorption, infection, contour irregularity, and revision surgery among patients receiving autologous grafts vs IHCC vs Tutoplast cartilage grafts. Results: Of 576 unique citations, 54 studies were included in our systematic review; 28 studies were included after applying inclusion and exclusion criteria. Our search captured 1041 patients of whom 741 received autologous grafts and 293 received IHCC grafts (regardless of type). When autologous cartilage (n = 748) vs IHCC (n = 153) vs Tutoplast cartilage (n = 140) grafts were compared, no difference in warping (5%; 95% CI, 3%-9%), resorption (2%; 95% CI, 0%-2%), contour irregularity (1%; 95% CI, 0%-3%), infection (2%; 95% CI, 0%-4%), or revision surgery (5%; 95% CI, 2%-9%) was found. Conclusions and Relevance: No difference was found in outcomes between autologous and homologous costal cartilage grafts, including rates of warping, resorption, infection, contour irregularity, or revisions, in patients undergoing dorsal augmentation rhinoplasty. En bloc dorsal onlay grafts are commonly used in augmentation rhinoplasty to provide contour and structure to the nasal dorsum.

Reconstruction of animal bite injuries to the head and neck.

PURPOSE OF REVIEW: The aim if this review is to provide an update on the existing literature of animal bite treatment strategies and provide a systematic approach to animal bites from presentation to reconstruction. RECENT FINDINGS: Dog bites cause 80-90% of animal bites with 26.8-56.5% occurring in the head and neck. Infection rates may be as low as 5.7-9.7%. Primary closure alone is sufficient in 69.8% of dog bites within the first 24 h. SUMMARY: Animal bite injuries to the head and neck are common, especially in the younger population. Dogs cause a majority of these bite injuries. Injuries can include simple lacerations or punctures, avulsions with tissue present, or avulsions with loss of tissue. The most common locations are the cheek, nose, and lips. It is important to gather the vaccination status of the animal and patient and to administer tetanus/rabies prophylaxis if indicated. Antibiotics are typically prescribed for 3-5 and 7-14 days for uninfected and infected wounds, respectively. These wounds require evaluation, irrigation, and occasionally debridement or repair in the operating room. The type of repair is determined based on the location and extent of injury and can range from primary closure to microsurgical replantation, skin grafts, flaps, or even facial transplantation.

Utility of the LACE Scoring System in Predicting Readmission Following Tracheotomy and Laryngectomy.

In the current value-based health-care environment, 30-day unplanned hospital readmissions have been identified as a quality measure and an opportunity to help reduce health-care costs. The LACE Index Scoring Tool for Risk Assessment of Death and Readmission utilizes length of stay, acuity of admission, comorbidities, and emergency department visits to stratify patients into high and low risk of readmission. A retrospective chart review of 161 patients who underwent a tracheotomy or laryngectomy for head and neck indications at a tertiary care academic center demonstrated that the readmitted patient cohort was not statistically or clinically different from the nonreadmitted cohort when comparing LACE scores ( P = .789), length of hospital stay ( P = .237), discharge disposition ( P = .569), or insurance status ( P = .85). Addressing the problem of unplanned 30-day readmissions will likely require enhanced patient education, improved coordination of care, and further research.

Reflections on Shared Decision Making.

Decisions about medical and surgical treatment can be complex-even for health care providers, who can struggle with which treatment option to offer their patients. In the current landscape of patient-centric value-based health care, the need for appropriate medical decision making to maximize treatment outcomes is evermore important. Shared decision making is a process in which clinicians and patients make decisions together using the best available evidence while accounting for the patients' values and beliefs. A patient-centered approach has been associated with improved patient satisfaction, clinical outcomes, and patient adherence to treatment. Only by taking a collaborative care approach among patients, physicians, and caregivers can we hope to deliver the best possible care and improve our outcomes for each and every patient.

A 3-Dimensional-Printed Short-Segment Template Prototype for Mandibular Fracture Repair.

IMPORTANCE: After reduction of complex mandibular fractures, contouring of the fracture plates to fixate the reduced mandibular segments can be time-consuming. OBJECTIVE: To explore the potential application of a 3-dimensional (3-D)-printed short-segment mandibular template in the management of complex mandibular fractures. DESIGN, SETTING, AND PARTICIPANTS: A feasibility study was performed at a tertiary academic center using maxillofacial computed tomography data of 3 patients with comminuted mandibular fractures who required preoperative planning with a perfected complete mandible model. INTERVENTIONS: Thresholding, segmentation, and realignment of the fractured mandible were performed based on computed tomography data. Each reduced mandible design was divided to create 3-D templates for 6 fracture sites: right and left angle, body, and symphyseal/parasymphyseal. Sessions were conducted with junior otolaryngology and plastic surgery residents, during which mandibular fracture plates were contoured in a "preoperative" setting against the 3-D-printed short-segment templates, and an "intraoperative" setting against the previously manufactured, complete mandible model. The previously manufactured, complete model served as a surrogate for the intraoperative mandible with the fracture site reduced. MAIN OUTCOMES AND MEASURES: The time for 3-D template printing, the "preoperative" (measure of the time consumed preoperatively), and "intraoperative" (measure of the time saved intraoperatively) times were recorded. Comparisons were made for cost estimates between a complete model and the 3-D-printed short-segment template. The operating room charge equivalent of the intraoperative time was also calculated. RESULTS: Of the 3 patients whose data were used, 1 was a teenager and 2 were young adults. The total time for 3-D modeling and printing per short-segment template was less than 3 hours. The median (range) intraoperative time saved by precontouring the fracture plates was 7 (1-14), 5 (1-30), and 7 (2-15) minutes, and the operating room charge equivalents were $350.35 ($50.05-$700.70), $250 ($50.05-$1501.50), and $350.35 ($100.10-$750.75) for the angle, body, and symphyseal/parasymphyseal segments, respectively. The total cost for a single 3-D-printed template was less than $20, while that for a perfected complete model was approximately $2200. CONCLUSIONS AND RELEVANCE: We demonstrate that patient- and site-specific 3-D-printed short-segment templates can be created within the timeframe required for mandibular fracture repair. These novel 3-D-printed templates also demonstrate cost efficiency in the preoperative planning for complex mandibular fracture management compared with perfected models and facilitate plate contouring in a similar fashion. Estimation of reduced operative room cost and time with the application of these short-segment templates warrants studies in actual patient care. LEVEL OF EVIDENCE: NA.
