A Look Back: A Single Surgeon's Experience Using Virtual Surgical Planning in Adult Orthognathic Surgery.

The evolution of virtual surgical planning (VSP) in the last 2 decades has led to improved precision and efficiency for orthognathic surgery, both pre- and intraoperatively. This study evaluates a single surgeon's experience with this technology over the past 6 years. Patients undergoing orthognathic surgery using VSP with the senior author between 2015 and 2021 were retrospectively reviewed. Virtual surgical planning -specific data including incidence of midline/cant correction, occlusal equilibration, serial splints, segmental osteotomies, and custom plates were recorded and analyzed. Sixty patients undergoing orthognathic surgery using simulated VSP in the study period were retrospectively reviewed. Mean age at time of surgery was 23.5±7.9 years. Forty-nine patients (81.7%) underwent LeFort I osteotomy combined with at least 1 additional procedure (eg,unilateral or bilateral sagittal split osteotomy, condylectomy, genioplasty, etc.). Twenty-six (43.3%) of patients in the studied cohort underwent maxillary midline correction, 30.0% required occlusal equilibration, 36.7% underwent maxillary molar cant correction, 30.0% underwent mandibular cant correction, and 21.7% required both maxillary and mandibular cant correction. Three patients required serial splinting, and 15 patients (25.0%) required modification of splint design. Custom plates were utilized in 15 patients (25.0%). This study demonstrates the utility of VSP in accurately detecting occlusal cants, asymmetry, and occlusal interferences. Virtual surgical planning also allows for a dynamic preoperative planning process, offering the surgeon a high degree of versatility in splint design, and the ability to fabricate multiple customized splints for each case. This is particularly useful in patients with limited or unpredictable soft tissue elasticity.

Prevalence of Comorbid Psychiatric Conditions and Chronic Pain in Patients Seeking Peripheral Nerve Surgery.

Background: In peripheral nerve surgery, the presence of psychiatric diagnoses and medications may affect outcomes and perioperative neuropathic pain management. The purpose of this study was to determine the prevalence of psychiatric diagnoses and chronic pain in patients referred to a peripheral nerve surgery clinic. Methods: This is a retrospective review of patients seen at a peripheral nerve clinic from July 1, 2017 to June 30, 2021. Medical records were reviewed for demographics; peripheral nerve diagnosis; psychiatric diagnoses; psychotropic prescriptions; use of nonneuroleptic/nonnarcotic, neuroleptic, and narcotic medications; and peripheral nerve surgical candidacy and outcome. Results: Six hundred twenty-two patients were included in this study. The most common reasons for referral were 24.8% lower extremity neuroma, 23.2% lower extremity compressive neuropathy, and 14.0% upper extremity compressive neuropathy. Of the included patients' 37.1% had a psychiatric diagnosis, and 36.3% were taking a psychotropic medication. The percentage of patients taking chronic nonneuroleptic/nonnarcotic pain medications was 34.3%' with 42.8% taking neuroleptic, and 24.9% narcotic medications. Patients with a psychiatric diagnosis were more likely to be taking neuroleptic (48.9% versus 38.9%, P < 0.001) and narcotic pain medications (27.3% versus 17.4%, P = 0.004) and less likely to have a positive surgical outcome (65.7% versus 83.0%, P = 0.001). Conclusions: Patients referred to a peripheral nerve surgery clinic frequently have psychiatric diagnoses and take chronic psychotropic and chronic pain medications. Knowledge of this will best help the peripheral nerve surgeon evaluate a patient for surgery, optimize perioperative care, and safely and effectively manage expectations.

Custom Plates in Orthognathic Surgery: A Single Surgeon's Experience and Learning Curve.

BACKGROUND: Virtual surgical planning (VSP) now allows for the fabrication of custom plates in orthognathic surgery. The senior author was an early adopter, using VSP and stereolithographic splints for over a decade, before transitioning to custom plates in 2019. The authors present our experience and learning curve with this new technology and compare results to a prior cohort of orthognathic patients. METHODS: A retrospective chart review identified patients undergoing orthognathic surgery with the senior author between 2016 and 2021. All underwent VSP and stereolithographic splint formation, and then either traditional or custom-plate fixation. Demographics, perioperative variables, and postoperative outcomes were analyzed. Traditional fixation consisted of craniomaxillofacial plates, bent intraoperatively by the surgeon to adapt to the facial skeleton. Custom plates were prefabricated and prebent to fit drill holes outlined by customized cutting guides. RESULTS: Forty-three patients underwent surgery in the study period, 25 (58.1%) with traditional fixation hardware and 18 (41.9%) with custom plates. The surgical technique evolved throughout the custom-plate cohort, with the most recent technique involving custom maxillary plate fixation and traditional mandibular plate fixation. When comparing this group of patients to the prior cohort of traditional fixation patients, operative time significantly decreased (mean 233 minutes versus 283 minutes, P = 0.044), without significant difference in complications. CONCLUSIONS: Patient-specific cutting guides and custom plates allow for precise spatial positioning of the osteotomized jaw in the orthognathic surgery. Unsurprisingly, obstacles must be overcome in adopting this new technology; here, we outline our experience and technical modifications that have resulted in increased surgical efficiency with comparable outcomes.

Incidence and Nerve Distribution of Symptomatic Neuromas and Phantom Limb Pain after Below-Knee Amputation.

BACKGROUND: Patients with major lower limb amputations suffer from symptomatic neuromas and phantom-limb pain due to their transected nerves. Peripheral nerve surgery techniques, such as targeted muscle reinnervation and regenerative peripheral nerve interface, aim to physiologically prevent this nerve-specific pain. No studies have specifically reported on which nerves most frequently cause chronic pain. The authors studied the nerve-specific incidence of symptomatic neuroma formation and phantom limb pain in patients undergoing a below-knee amputation, to better tailor use of targeted muscle reinnervation and regenerative peripheral nerve interface. METHODS: This was a retrospective review of all patients undergoing a below-knee amputation from January 1, 2013, to December 31, 2018, at MedStar Georgetown University Hospital. All below-knee amputations were performed with a posterior skin flap, myotenodesis, and traction neurectomies of all nerves. Postoperative notes were reviewed for the presence of a symptomatic neuroma, defined as localized pain and a Tinel sign over a known sensory nerve, and nerve-specific phantom limb pain, defined as pain of the missing limb corresponding to a known dermatome. RESULTS: One hundred ninety-eight patients were included in this study. The rate of symptomatic neuroma formation was 14.6 percent (29 of 198), with the superficial peroneal and saphenous nerves most often involved. Diabetes and obesity were protective against symptomatic neuroma formation. The rate of nerve-specific phantom limb pain was 12.6 percent (25 of 198) and highly correlated with the presence of a symptomatic neuroma. CONCLUSION: To optimize outcomes for amputees, it is critical that surgeons best understand what nerves are more likely to form symptomatic neuromas and lead to nerve-specific phantom limb pain, so that surgeons can best tailor primary or secondary management of the major sensory nerves. CLINICAL QUESTION/LEVEL OF EVIDENCE: Risk, III.

The Syringe External Fixator: Short- and Medium-Term Functional Outcomes From This Inexpensive and Customizable Treatment for Comminuted Intra-Articular Fractures of the Hand.

PURPOSE: Comminuted intra-articular fractures and fracture dislocations of the metacarpophalangeal (MCP) and interphalangeal joints are challenging. Dynamic external fixation, permitting early joint motion while still minimizing forces across the healing joint, can result in acceptable postoperative active range of motion (AROM). However, some fractures are not initially stable enough for early dynamic motion; further, many available dynamic external fixation systems are costly and cumbersome. We reviewed our experience using an external fixator made from a 1-mL syringe and K-wires and report outcomes using it as a static fixator, dynamic fixator, or configured as a static fixator and then converted to a dynamic fixator in the clinic. METHODS: Patients with intra-articular fractures and fracture dislocations of the MCP and proximal interphalangeal (PIP) joints treated between 2014 and 2020 using syringe external fixators were retrospectively reviewed. We reviewed demographics, mechanisms, treatment types and durations, and postoperative AROM, as well as complications including infection, pin loosening, nonunion, hardware failure, and need for further surgery. Patients were analyzed by the level of joint injury (MCP versus PIP) and by treatment pattern. RESULTS: After excluding 23 patients with 25 joint injuries who were lost to follow-up or had inadequate outcome data, 27 patients with 29 joint injuries were reviewed. The average follow-up was 171 days after surgery. The postoperative AROM at the MCP level averaged 55° for static fixation and 30° for static-to-dynamic fixation. The postoperative AROM at the PIP level averaged 64° for static fixation, 66° for static-to-dynamic fixation, and 80° for dynamic fixation. Three pin site infections and 2 loose pins were reported. CONCLUSIONS: The syringe external fixator is an inexpensive, effective, and customizable treatment for intra-articular MCP and interphalangeal fractures and fracture dislocations, and results in acceptable postoperative AROM outcomes and complication rates. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.

Should Antiplatelet Therapy Be Withheld Perioperatively? The First Study Examining Outcomes in Patients Receiving Dual Antiplatelet Therapy in the Lower Extremity Free Flap Population.

BACKGROUND: Antiplatelet agents are typically withheld perioperatively because of bleeding concerns. Dual antiplatelet therapy, such as aspirin and clopidogrel, has significant morbidity and mortality benefits in patients with ischemic heart disease or peripheral vascular disease. This study aims to evaluate the impact of perioperative dual antiplatelet therapy in the lower extremity free tissue transfer population. METHODS: Lower extremity free tissue transfers performed by the senior author (K.K.E.) from 2011 to 2019 were retrospectively reviewed. Demographics, comorbidities, perioperative dual antiplatelet therapy, and free tissue transfer characteristics were recorded. Outcomes of interest included flap success, hematoma formation, blood transfusion requirements, and cardiac event occurrence. RESULTS: One hundred ninety-five free tissue transfers were included. Median age at the time of free tissue transfer was 56.5 years. Median Charlson Comorbidity Index was 3. Thirty-four patients were on clopidogrel, which was either withheld (n = 20) or continued (n = 14) on the day of free tissue transfer. Incidence of blood transfusion was significantly higher in both the withheld and continued versus nonclopidogrel groups. Flap success was statistically equivalent between groups (withheld, 90.0 percent; continued, 92.9 percent; nonclopidogrel, 95.0 percent; p = 0.346). Cardiac events occurred most often in the continued group (21.4 percent) compared to the withheld (5.0 percent) and nonclopidogrel (0.6 percent) groups. On multivariate analysis, holding clopidogrel remained significant for increased odds of postoperative transfusion. The clopidogrel group was no longer significant for intraoperative transfusion. CONCLUSIONS: Despite increases in volume of blood products transfused, free tissue transfer can be performed safely with perioperative dual antiplatelet therapy. Withholding dual antiplatelet therapy on the day of free tissue transfer was not associated with decreased intraoperative transfusion; thus, dual antiplatelet therapy can safely be continued throughout the operative course to minimize cardiovascular risk. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, III.

Retention Sutures and Negative Pressure Wound Therapy for Delayed Primary Closure of Fasciotomy Wounds.

Achieving primary closure of lower extremity fasciotomy wounds is difficult. Surgeons are faced with the option of waiting potentially long periods of time for edema to reside, in order to attempt delayed primary closure (DPC) versus closing at an earlier time with a split thickness skin graft. DPC offers superior aesthetic outcomes than split thickness skin grafts but traditionally cannot occur until later in the clinical course once excessive edema has subsided. We present a case of a young athlete with compartment syndrome, which was managed with an alternative technique for achieving DPC: serial partial closure under tension with retention sutures and negative pressure wound therapy. The successful outcome in this single case should prompt further studies investigating the objective benefits of this novel method to achieve DPC following fasciotomy.

Idiopathic Pediatric Tibial Nerve Palsy.

Tibial nerve entrapment is uncommon in the pediatric population, and presents diagnostic and treatment challenges. We present the unusual case of a 3-year-old male child with progressive lower leg atrophy of an unknown etiology. Preoperative electrodiagnostic testing and magnetic resonance imaging suggested proximal tibial neuropathy. Surgical exploration showed compression of the tibial nerve at the inferior fascial edge of the long head of the biceps femoris and at the soleal sling. Release and external neurolysis led to improvement of distal leg motor function.

Dental Topics for Plastic Surgeons, Part Three: Infection and Trauma of the Dentition.

ABSTRACT: Conditions that affect dental and periodontal structures receive sparse coverage in the plastic surgery literature, yet a working knowledge of this subject matter is important in certain areas of clinical practice and a fundamental understanding is part of plastic surgery competency tested on the in-service and written board examinations. This 4-part series written to provide plastic surgeons with a working knowledge of dental topics that may be relevant to their clinical practice. This section, Part III, covers inflammatory and infectious conditions of the dentition and related structures, as well as dentoalveolar trauma.

Pediatric Ectopic Nail Formation following Fingertip Trauma: A Case Report and Literature Review.

Post-traumatic ectopic nail is an uncommon entity that is occasionally observed after trauma to the fingertip and nail, resulting in aesthetic and functional morbidity. We report a case of post-traumatic ectopic nail in a 3-year-old girl following trauma to her index finger and subsequent surgical intervention to remove an inclusion cyst. The unusual clinical sequence is presented to highlight the etiology and treatment of this rare lesion.

Negative pressure wound therapy with intermittent instillation of rifampin for the treatment of an infected vascular bypass graft.

Negative pressure wound therapy with intermittent instillation, especially with the addition of antibiotics in the case of infection, is a versatile treatment modality for the closure of wounds and can be used both primarily after débridement and secondarily after failure of muscle flap coverage. We present a case in which negative pressure wound therapy with intermittent instillation of rifampin was used to successfully close a groin wound secondary to an infected prosthetic vascular graft that initially failed to close with a muscle flap. Consideration of this approach to wound closure and graft salvage is important because of the seriousness and relatively common incidence of prosthetic vascular graft infection after infrainguinal arterial bypass revascularization.

Adverse Event Incidences following Facial Plastic Surgery Procedures: Incorporating FACE-Q Data to Improve Patient Preparation.

BACKGROUND: Before creation and validation of the FACE-Q by Pusic et al., adverse event types and incidences following facial cosmetic procedures were objectively measured and reported by physicians, potentially leading to misrepresentation of the true patient experience. This article analyzes and compares adverse event data from both FACE-Q and recent review articles, incorporating patient-reported adverse event data to improve patient preparation for facial cosmetic procedures. METHODS: FACE-Q adverse event data were extracted from peer-reviewed validation articles for face lift, rhinoplasty, and blepharoplasty, and these data were compared against adverse effect risk data published in recent Continuing Medical Education/Maintenance of Certification and other articles regarding the same procedures. RESULTS: The patient-reported adverse event data sets and the physician-reported adverse event data sets do contain overlapping elements, but each data set also contains unique elements. The data sets represent differing viewpoints. Furthermore, patient-reported outcomes from the FACE-Q provided incidence data that were otherwise previously not reported. CONCLUSIONS: In the growing facial cosmetic surgery industry, patient perspective is critical as a determinant of success; therefore, incorporation of evidence-based patient-reported outcome data will not only improve patient expectations and overall experience, but will also reveal adverse event incidences that were previously unknown. Given that there is incomplete overlap between patient-reported and physician-reported adverse events, presentation of both data sets in the consultation setting will improve patient preparation. Furthermore, use of validated tools such as the FACE-Q will allow surgeons to audit themselves critically.
