"Emergency Room Incision and Drainage of Perirectal Abscess is Equivalent to Incision and Drainage in the Operating Room".

BACKGROUND: Current guidelines for management of anorectal abscesses make no recommendations for operative vs bedside incision and drainage (I&D). The purpose of this study was to determine if management in the operating room is necessary to adequately drain anorectal abscesses and prevent short-term complications for patients presenting to the emergency department (ED). METHODS: Patients with perirectal abscesses were identified and divided into two groups based on intervention type: "bedside" or "operative." Demographic, laboratory, and encounter data were obtained from the medical record. Study outcomes included 30-day complications (return to the ED, reintervention, and readmission). Data were analyzed with univariate and multivariate analyses using SPSS (version 28). RESULTS: A total of 113 patients with anorectal abscesses were identified. Sixty-six (58%) underwent bedside I&D and 47 (42%) operative I&D. The overall complication rate was 10%. A total of 9 patients (6 bedside and 3 operative) returned to the ED. Six of these patients required reintervention (5 bedside and 1 operative), and 1 was readmitted. Two patients from the bedside group required a second I&D during their index admission. Pre-procedure SIRS (P = .02) was found to be associated with 30-day complications. Provider specialty and training level were not associated with 30-day complications. DISCUSSION: In this study, for patients presenting to the ED, bedside drainage was found to be an adequate management strategy to achieve complete drainage without a significant increase in the rate of complications when compared to operative drainage.

A Comprehensive Single-Center Analysis of Postoperative Nausea and Vomiting Following Orthognathic Surgery.

BACKGROUND: Postoperative nausea and vomiting (PONV) remains a major clinical end-point for directing enhanced recovery after surgery (ERAS) protocols in facial plastic surgery. This study aimed to identify risk factors for PONV and evaluate strategies for PONV reduction in orthognathic surgery patients. METHODS: A retrospective cohort study was performed among patients receiving orthognathic surgery at our institution from 2011 to 2018. Patient demographics, surgical operative and anesthesia notes, medications, and nausea/vomiting were assessed for each patient. The amount of opioid analgesia given both perioperatively and postoperatively was recorded and converted into morphine equivalents (MEQ). Stepwise regression analysis was used to identify significant risk factors for PONV. Post hoc analyses were employed to compare PONV among patients based on MEQ dosage and antiemetic prophylaxis regimes. RESULTS: A total of 492 patients were included; mean age was 23.0 years (range: 13-60); 54.4% were female. The majority of patients received concurrent Le Fort I osteotomy, BSSO, and genioplasty (70.1%). During hospitalization, 59.4% of patients experienced nausea requiring antiemetic medications and 28.4% experienced emesis. Stepwise regression yielded Apfel scores (P = 0.003) and postoperative opioids (P = 0.013) as the strongest predictors of PONV. Post hoc analyses showed that undertreatment with prophylactic antiemetics (based on Apfel) predicted increased PONV (+12.9%, P = 0.020), and that lower postoperative MEQs (<28.0) predicted decreased PONV (-11.8%, P = 0.01). CONCLUSIONS: The study findings confirm the high incidence of PONV among orthognathic surgical patients and stratify previously reported PONV risk factors. More aggressive utilization of antiemetic medications and decreased dependence on opioid analgesia may decrease nausea/vomiting following orthognathic surgery.

Decreasing Inpatient Opioid Use Following Orthognathic Surgery.

PURPOSE: Strategies to decrease postoperative opioid use are important for mitigating the immediate and long-term risks associated with their use. We aimed to investigate the impact of perioperative various factors on inpatient opioid needs for patients undergoing orthognathic surgery. METHODS: This was a retrospective cohort study of all patients who underwent orthognathic surgery performed by the senior author from 2012 to 2018. Patients were grouped into intravenous (IV) acetaminophen and no-IV acetaminophen cohorts. Opioid medications received by patients during hospital stay were converted to mean morphine equivalents (MME) for comparison. Additional factors that influenced opioid consumption, such as transexamic acid (TXA) and postoperative nausea and vomiting (PONV), were identified using univariate analysis. Factors found to have statistical significance were added to a multivariate linear regression model. RESULTS: 319 patients were included. Those who received IV acetaminophen had lower rates of total opioid use (57.3 versus 74.8 MME; P = 0.002) and postoperative opioid use (24.0 versus 37.7 MME; P < 0.001). Perioperative prothrombotic agents, such as TXA, were associated with lower total and postoperative MME (P = 0.005, P = 0.002). Multivariate regression analysis showed that increased PONV resulted in increased postoperative opioid use, whereas perioperative acetaminophen lowered total and postoperative quantities. CONCLUSIONS: Perioperative IV acetaminophen is an effective method for decreasing inpatient opioid analgesia after orthognathic surgery. Intravenous TXA and PONV control may provide additional benefit to decreasing inpatient opioid consumption. More research as to the mechanisms and ideal clinical applications for both IV acetaminophen and TXA are warranted.

Spatial Analysis of the Temporomandibular Joint and Condyle Following Mandibular Distraction in Robin Sequence.

ABSTRACT: To comprehensively assess changes in temporomandibular joint and mandibular condyle morphology in Robin sequence (RS) patients undergoing mandibular distraction osteogenesis (MDO). A retrospective analysis of pediatric patients with RS and functional temporomandibular joints who underwent MDO by a single surgeon was performed. Preoperative and postoperative computed tomography (CT) scans were morphometrically analyzed three-dimensional in 3-matic and Mimics (Materialise). Comparative analysis was performed using Wilcoxon signed-rank tests. Fourteen RS patients were included (28 condyles, 56 CT scans), 78% male and 22% females. The mean age at surgery was 9.4 weeks (range 1.6-46.7 weeks). The average age at initial CT was 5.3 days (range 0-11 days). The mean time interval for CT scan before MDO and after hardware removal were 8.8 ±â€Š6.4 days and 11.2 ±â€Š25.8 days, respectively. Rotatory changes of the condyle revealed a significantly decreased horizontal angle following MDO (-7.55°, 95% confidence interval -11.13° to -3.41°; P < 0.001). Anteroposteriorly, the angle between condylar process and ramus (incline) increased significantly (14.14°, 95% confidence interval 10.71°-19.59°; P < 0.001). Intragroup analysis revealed no difference between left versus right condylar position measurements. The condyle itself increased in size and length and the intercondylion distance increased post-MDO. There were no complications and all patients achieved relief of airway obstruction without tracheostomy. Morphologic and positional changes of the mandibular condyle following MDO in RS patients parallel changes that occur during normal development in non-RS patients. As a result, MDO may facilitate normal condylar morphology and function in RS patients.

Perception of femininity and attractiveness in Facial Feminization Surgery.

BACKGROUND: Facial Feminization Surgery (FFS) alters bone and soft tissue to feminize facial features of transgender females. This study aims to evaluate perceptions of femininity, attractiveness, and ideal surgical outcomes in transgender females, non-transgender females and plastic surgeons. METHODS: The data was extracted from a survey of transgender females (n=104), non-transgender females (n=192) (completion rate of 48.4%) and plastic surgeons who performed FFS (n=23) (survey response rate of 31.5%). Five virtually-modified forms of three facial features, the nasal tip width, supratip break, mandibular gonial angles, and the composite images of the above features of an individual, assigned male at birth, were used. Respondents were requested to select and rank images based on personal perceptions of femininity and attractiveness. RESULTS: Transgender females chose a narrower nasal tip width as more attractive (P≤0.001), and evaluated a more acute supratip angle, and more obtuse mandibular gonial angle as both more feminine and attractive (all P≤0.023) compared to non-transgender females. Plastic surgeons chose a more obtuse mandibular gonial angle as more feminine (P=0.007) and a more ideal surgical outcome (P=0.046), compared to transgender female respondents. In the assessment of composite images, non-transgender female ranked the options with more obtuse mandibular gonial angle as more feminine (all P≤0.036) than transgender females. CONCLUSIONS: Acknowledging the difference in transgender females' perceptions of facial femininity and attractiveness from non-transgender females and plastic surgeons could assist plastic surgeons in managing expectations of surgical outcomes.

Orthognathic Surgery to Improve Facial Profile: Assessment, 3-Dimensional Planning, and Technique.

A concave profile with class III malocclusion is most often due to a combination of maxillary hypoplasia and mandibular hyperplasia. Surgical correction entails normalization of jaw positions and is more challenging in the setting of concurrent asymmetry and open bite. Treatment should optimize both facial harmony and occlusion. Orthognathic surgery for class III deformities occurs at skeletal maturity and should address all aspects of the condition while preventing unnecessary emotional stress from delayed treatment. In this article, the authors describe the 3-jaw orthognathic surgery technique to address maxillary hypoplasia, mandibular prognathism, open bite, and mandibular asymmetry in a single procedure. The process of preoperative 3-dimensional (3D) virtual surgical planning, detailed surgical technique, fat grafting, and a comparison of preoperative and postoperative 3D aesthetic outcomes is presented. Additionally, a retrospective review of postoperative outcomes of 54 patients who received 3-jaw orthognathic surgery is presented as well.

Aesthetic Rhinoplasty: Technique, 3-Dimensional Simulation, and Outcome Assessment.

Communication of goals and realistic expectations between the surgeon and patient is a crucial step of aesthetic rhinoplasty. Three-dimensional (3D) imaging technology allows for sharing of simulated outcomes in the office setting, thereby facilitating this process. This article highlights the use of 3D rhinoplasty simulation in preoperative assessment and the senior author's preferred surgical technique in open rhinoplasty.

Crushed Cartilage and Autologous Fat for Dorsal Nasal Refinement.

BACKGROUND: Dorsal contour irregularities remain a potential undesirable sequela of rhinoplasty. Use of dorsal onlay grafts can camouflage such irregularities. In this article, a novel technique for dorsal onlay grafting utilizing crushed cartilage mixed with autologous fat is described. This study aims to assess long-term graft retention and aesthetic outcomes with this technique. METHODS: Patients with >18-month follow-up who underwent primary open rhinoplasty with the described technique were reviewed. Three-dimensional photographs taken at multiple timepoints were overlaid with volumetric subtraction used to quantify graft retention. The Rhinoplasty module of the FACE-Q was completed by each patient, and the Rhinoplasty Assessment Scale Photographic (RASP) was completed by surgeon reviewers. Pre- and postoperative changes in dorsal height as well as RASP scores were compared with paired t-tests. Changes in BMI, dorsal volume, and dorsal height were compared with linear regression. P values <0.05 were considered significant. RESULTS: Fourteen patients were included, mean age 32. Mean intermediate and final follow-up was 17.8 months and 28.9 months, respectively. There were no statistically significant dorsal height change (mean = 0.0 mm, p = 0.91) and minimal dorsal volume change (mean = 0.02 cm3, range:  0.08 to 0.13). Patients reported a high degree of satisfaction with facial/nasal appearance and psychological/social functioning. There was a statistically significant improvement in RASP scores (p < 0.001) postoperatively. CONCLUSION: Crushed septal cartilage mixed with autologous fat is an effective option for dorsal nasal onlay in rhinoplasty and is associated with excellent graft retention, patient satisfaction, and nasal aesthetics.

Conformity of the Virtual Surgical Plan to the Actual Result Comparing Five Craniofacial Procedure Types.

BACKGROUND: The "accuracy" of virtual surgical planning across multiple procedure types is not known. The authors aimed to compare the planned outcome from virtual surgical planning to the actual postoperative outcome for five craniofacial procedure types performed by a single surgeon: implant cranioplasty, cranial vault remodeling, orthognathic surgery, mandible reconstruction, and mandibular distraction. METHODS: Stereolithography formats were obtained from virtual surgical planning and compared to postoperative computed tomographic scans for consecutive patients who underwent one of the five procedure types. Volumetric renderings of the operated bony region of interest were overlaid and compared using a Boolean operation to compute conformity (as a percentage of the region of interest). Conformity across procedure type was analyzed using analysis of variance and post hoc Bonferroni analysis, where appropriate. RESULTS: One hundred thirty patients were included (51.5 percent male and 49.5 percent female; mean age, 27 years; 59 orthognathic surgery, 32 cranial vault remodeling, 16 mandible reconstruction, 12 mandibular distraction, and 11 implant cranioplasty patients). The highest tier of conformity was obtained for implant cranioplasty (median, 76.8 ± 10.3 percent) and mandible reconstruction (mean, 69.4 ± 11.2 percent), followed by orthognathic surgery (mean, 55.0 ± 7.3 percent) and mandibular distraction (median, 41.9 ± 20.3 percent), followed by cranial vault remodeling (mean, 22.2 ± 12.1 percent) (p < 0.001 between tiers and p > 0.05 among tiers). CONCLUSIONS: Virtual surgical planning resulting in custom permanent implants and intraoperative guides provides more predictable results compared to virtual surgical planning used for procedures involving higher degrees of skeletal repositioning and postoperative movement (i.e., mandibular distraction and nonrigid cranial vault remodeling). In cases with expectedly lower conformity, excellent outcomes can be achieved with sound intraoperative judgment.

Three-Dimensional Analysis and Surgical Planning for Open Correction of Trigonocephaly.

SUMMARY: Metopic craniosynostosis results in trigonocephaly, characterized by a triangular forehead with metopic ridge, bitemporal pinching, and narrow-set eyes with recessed lateral orbital rims. Surgical management is controversial but may include open expansion and vault remodeling, to enhance neurocognitive and aesthetic outcomes. This article and video vignette depict the diagnosis and treatment of metopic craniosynostosis, demonstrating the senior author's open approach, three-dimensional virtual surgical planning, and technical steps.

Concurrent High Condylectomy and Orthognathic Surgery for Treatment of Patients With Unilateral Condylar Hyperplasia.

BACKGROUND: Facial asymmetry from unilateral condylar hyperplasia (UCH) may be definitively treated in the presence of active disease (with high condylectomy and concurrent orthognathic surgery) or after waiting for disease inactivity (orthognathic surgery alone). There is currently no consensus on the standard of care. In this study, we sought to compare functional and esthetic outcomes, as well as treatment duration, between these 2 management options. METHODS: Patients who underwent treatment for UCH were identified through retrospective review. Pre- and postoperative 3-dimensional (3D) images were obtained. Short- and long-term operative outcomes of those treated during the active (group 1) were compared to those treated in the inactive phase (group 2). Total treatment time, operative time, and length of hospital stay were evaluated. Facial asymmetry was also assessed by laypersons using a Likert scale. RESULTS: Fifteen patients (mean 25.6 years, range 14-56) were included: 6 in group 1 and 9 in group 2. All surgical outcomes were statistically independent of procedure type. Treatment time was significantly longer in the group 2 (P = 0.03). Both groups demonstrated significant improvement in facial asymmetry scores postoperatively with no significant difference in pre- or postoperative asymmetry between groups (P = 0.64). CONCLUSIONS: In patients with active UCH, high condylectomy and orthognathic surgery is a procedure that restores facial symmetry and improves jaw function while halting mandibular growth. Good esthetic and functional outcomes, as well as reduced treatment time and disease burden, support the use of this treatment option for this population.

Vascularized Composite Parietal Bone Flap for Immediate Reconstruction of a Hemi-Maxillectomy Defect in an Infant.

BACKGROUND: Surgical resection of maxillary tumors can result in defects that can be difficult to reconstruct by conventional means due to the complex functional and anatomic nature of the midface and lack of regional bone flap options in the head and neck. Many reconstructive methods have been used to repair maxillary defects, but the ideal technique for the reconstruction of hemi-maxillectomy defects in growing pediatric patients has yet to be determined. METHODS: The authors present a rare pediatric patient with melanotic neuroectodermal tumor of infancy resulting in a hemi-maxillectomy defect after resection that was reconstructed using a pedicled vascularized composite flap consisting of temporalis muscle, pericranium, and parietal bone. RESULTS: The patient achieved successful long-term bony reconstruction of his right maxilla with this flap. Stable skeletal fixation with adequate orbital support was maintained over a >3-year follow-up period. CONCLUSION: A vascularized composite parietal bone flap is a reliable reconstructive option for reconstruction of large maxillectomy defects providing low donor-site morbidity, adequate globe support, excellent long-term skeletal stability, and malar symmetry in rapidly growing pediatric patients. Successful reconstruction for a rare patient with maxillary melanotic neuroectodermal tumor of infancy requiring hemi-maxillectomy was demonstrated with >3-year follow-up.

Facial Asymmetry in Unilateral Condylar Hyperplasia: Comparing Treatment for Active versus Burnt-Out Disease.

BACKGROUND: Facial asymmetry caused by unilateral condylar hyperplasia requires treatment to address facial and occlusal imbalances. There is no definitive evidence to suggest that a single intervention strategy (during either active condylar overgrowth or the burnt-out phase) results in better/more symmetric correction. This study sought to quantify preoperative and postoperative facial asymmetry in unilateral condylar hyperplasia patients comparing treatment for active versus burnt-out disease. METHODS: Preoperative and postoperative three-dimensional photographs were obtained. Images were compared to those of unaffected controls as a standard for normal facial symmetry. Facial asymmetry was assessed using root-mean-square deviation. Paired t tests were performed to compare the root-mean-square deviations of preoperative and postoperative images between the unilateral condylar hyperplasia groups and against controls. RESULTS: Forty patients were included (11 active, nine burnt-out, and 20 controls) and 60 three-dimensional images were evaluated. Preoperatively, patients in the burnt-out group had worse asymmetry than those with active unilateral condylar hyperplasia (p = 0.011). Both groups demonstrated significantly improved symmetry postoperatively (active, p = 0.0069; burnt-out, p = 1.74E-4). However, burnt-out patients remained with some residual asymmetry (p = 4.75E-4), whereas their active counterparts showed no significant difference compared to unaffected controls (p = 0.089). CONCLUSIONS: Patients with end-stage unilateral condylar hyperplasia have more severe facial asymmetry that is more difficult to normalize compared to earlier intervention during active unilateral condylar hyperplasia. These findings suggest that, if possible, corrective intervention is preferable during active unilateral condylar hyperplasia. CLINICAL QUESTION/LEVEL OF EVIDENCE: Risk, II.

Rhinoplasty Using Three-Dimensional Analysis and Simulation.

Treatment of nasal deformity and obstruction requires analysis, planning, and precise execution of rhinoplasty techniques. When performed well, rhinoplasty is a powerful tool for achieving appealing nasal morphology and optimizing function. This article aims to highlight an open approach to septorhinoplasty using a number of techniques that are preferred by the senior author (D.M.S.) to successfully correct a congenital nasal deformity and deviated septum.

Concurrent High Condylectomy and Orthognathic Surgery to Address Mandibular and Facial Asymmetry.

Correction of facial asymmetry caused by active unilateral condylar hyperplasia (CH) requires proper diagnosis, arrested ongoing condylar growth, and ultimately orthognathic surgery. Traditionally, prior to performing orthognathic surgery, active CH is addressed either by: awaiting natural cessation of condylar overgrowth, or performing an interval high condylectomy (to stop growth). However, these strategies both add to the total treatment time, by either waiting and confirming no active growth, or performing a first stage growth-arresting procedure. In this report, the authors describe concurrent high condylectomy, and 3-jaw orthognathic surgery, to address the root of the problem and provide aesthetic correction in the same setting. This clinical series illustrates a detailed description of this approach, highlighting operative order, and an analysis of outcomes.

Alternatives to Autologous Bone Graft in Alveolar Cleft Reconstruction: The State of Alveolar Tissue Engineering.

Alveolar cleft reconstruction has historically relied on autologous iliac crest bone grafting (ICBG), but donor site morbidity, pain, and prolonged hospitalization have prompted the search for bone graft substitutes. The authors evaluated bone graft substitutes with the highest levels of evidence, and highlight the products that show promise in alveolar cleft repair and in maxillary augmentation. This comprehensive review guides the craniofacial surgeon toward safe and informed utilization of biomaterials in the alveolar cleft.A literature search was performed to identify in vitro human studies that fulfilled the following criteria: Level I or Level II of evidence, ≥30 subjects, and a direct comparison between a autologous bone graft and a bone graft substitute. A second literature search was performed that captured all studies, regardless of level of evidence, which evaluated bone graft substitutes for alveolar cleft repair or alveolar augmentation for dental implants. Adverse events for each of these products were tabulated as well.Sixteen studies featuring 6 bone graft substitutes: hydroxyapatite, demineralized bone matrix (DBM), ß-tricalcium phosphate (TCP), calcium phosphate, recombinant human bone morphogenic protein-2 (rhBMP-2), and rhBMP7 fit the inclusion criteria for the first search. Through our second search, the authors found that DBM, TCP, rhBMP-2, and rhBMP7 have been studied most extensively in the alveolar cleft literature, though frequently in studies using less rigorous methodology (Level III evidence or below). rhBMP-2 was the best studied and showed comparable efficacy to ICBG in terms of volume of bone regeneration, bone density, and capacity to accommodate tooth eruption within the graft site. Pricing for products ranged from $290 to $3110 per 5 mL.The balance between innovation and safety is a complex process requiring constant vigilance and evaluation. Here, the authors profile several bone graft substitutes that demonstrate the most promise in alveolar cleft reconstruction.
