Importance: Facial skeletal changes that occur with aging have critical importance to the aesthetics of the aging face and the field of facial rejuvenation. Patterns of bony change may differ based on race, but existing research is limited primarily to white or unspecified racial populations.

Objective: To longitudinally document patterns of facial skeletal change among black individuals.

Design, setting, and participants: This retrospective case series study evaluated the medical records of patients treated at an urban tertiary medical center and with at least 2 facial computed tomographic (CT) images obtained at least 6 years apart between 1973 and 2017. All patients were self-identified black adults initially aged 40 to 55 years with no history of facial surgery who required repeated facial CT imaging that included the entire midface and cranium. All data analysis took place between August 1, 2018, and October 31, 2018.

Main outcomes and measures: Facial CT scans were analyzed for 2-dimensional measurements to document changes in glabellar angle, bilateral maxillary angles, frontozygomatic junction width, orbital width, and piriform width.

Results: A total of 20 patients were included in our analysis (6 men, 14 women). The patients' mean (SD) initial age was 46.8 (5.8) years, with a mean (SD) follow-up of 10.7 (2.9) years. There was a significant increase in mean (SD) piriform aperture width from 3.24 (0.37) cm to 3.31 (0.32) cm (P = .002) and mean (SD) female orbital width from 3.77 (0.25) cm to 3.84 (0.19) cm (P = .04). There was a significant decrease in mean (SD) frontozygomatic junction width from 5.46 (1.38) mm to 5.24 (1.42) mm (P < .001). No significant differences were found in glabellar angles, maxillary angles, or male orbital width between initial and final imaging time points.

Conclusions and relevance: This study is the first to our knowledge to document longitudinal bony changes of the face among a population of black individuals. Although significant facial skeletal changes can be observed over an average 10-year period, they are minor in comparison to previously published data among whites. This study suggests that there may be significant differences in facial bony aging between races which may have an impact on the aesthetics of aging and hold implications for facial rejuvenation.

Importance: Despite advancements, treatment of mandibular body fractures is plagued by complications. Evaluation of a new plating system is needed with the goal of reducing complication rates.

Objectives: To evaluate the biomechanical behavior of a vertically oriented box plate vs traditional rigid internal fixation plating techniques for mandibular body fractures and to test if placement of the 3-dimensional plate oriented parallel to the fracture line provides improved rigidity and greater resistance to torsion, resulting in improved outcomes.

Design, setting, and participants: A mandible fracture model with synthetic replicas was used to compare resistance to torsional forces of different plating configurations. Additionally, a retrospective comparative review of the medical records of 84 patients with mandibular body fractures treated from 2005 to 2018 at Jacobi Medical Center, a level-1 trauma hospital in Bronx, New York, was completed.

Exposures: Patients sustained a mandibular body fracture and were treated with open reduction and internal fixation using metal plating.

Main outcomes and measures: In the comparative study of biomechanical behavior of various plating configurations, maximum torque sustained prior to deformation and loss of alignment was measured. Medical records were reviewed for surgical approach, plating techniques, operative time, length of admission, and rate of complications, including malocclusion, nonunion, infection, neurosensory disturbance, and wound dehiscence.

Results: Of the 84 patients included in the retrospective review, 76 (91%) were men, and the mean (SD) age was 29.7 (12.0) years. During biomechanical analysis, the vertical box plate provided greater stability and 150% of the resistance against torsional forces when compared with traditional linear plating. In the retrospective review, analysis showed vertical plating was associated with a lower incidence of postoperative neurosensory disturbance (25 [38%] patients treated with vertical plating vs 0 patients treated with box plating; P = .002) and a lower risk of any complication (41 [62%] vs 6 [33%], respectively; relative risk, 0.54; 95% CI, 0.27-1.06; P = .03). Vertical plating was associated with reduced operative time (134 minutes vs 70 minutes, respectively; P < .001).

Conclusions and relevance: This investigation suggests that vertical box plating is associated with a lower incidence of postoperative complications and reduced operative time compared with traditional plating techniques. The comparative biomechanical component demonstrated that the vertical box plate offered equal or greater resistance to torsional forces. Further studies of greater power and level of evidence are needed to more robustly demonstrate these benefits.

Importance: The soft palate contributes to deglutition, articulation, and respiration. Current reconstructive techniques focus on restoration of both form and function. The unique challenges of soft palate reconstruction include maintenance of complex upper aerodigestive tract function, with minimal local or donor site morbidity.

Objective: To review the literature on soft palate reconstruction and present an algorithm on how to approach soft palate defects based on this review.

Evidence review: A review of the literature for articles reporting studies on and that described concepts related to soft palate reconstruction was conducted in March 2017. In all, 1804 candidate titles and abstracts were independently reviewed. English-language articles that discussed acquired soft palate defect reconstruction were included. Non-English language studies without available translations, studies on primary soft palate defect reconstruction (ie, cleft palate repair) and primary cleft palate repair, studies in which the soft palate was not the focus of the article, and studies involving animals were excluded.

Findings: The following observations were made from the review of 92 included articles. Soft palate anatomy is a complex interplay of multiple structures working in a 3-dimensional area. Three of the authors created an initial algorithmic framework based on the selected studies. After this, a round table discussion among 3 authors considered experts was used to refine the algorithm based on their expert opinion. The 4 most important factors were determined to be defect size, defect extension to other subsites, defect thickness, and history of radiotherapy or planned radiotherapy. This algorithm includes both surgical and nonsurgical options. Defects in the soft palate not only affect the size and shape of the organ but, more critically, the function. The reconstructive ladder is used to help maximize the remaining soft palate functional tissue and minimize the effect of nonfunctional implanted tissue. Partial-thickness defects or defects less than one-fourth of the soft palate may not require locoregional tissue transfer. Patients with a history of radiotherapy or defects of up to 75% of the soft palate may require locoregional tissue transfer. Defects greater than 75% of the soft palate, defects that include exposure of the neck vasculature, or defects that include significant portions of the hard palate or adjacent oropharyngeal subsites may require free tissue transfer. Obturation should be considered a second-line option in most cases.

Conclusions and relevance: Ideal reconstruction of the soft palate relies on a comprehensive understanding of soft palate anatomy, a full consideration of the armamentarium of surgical techniques, consideration for adjacent subsite deficits, and a detailed knowledge of various intrinsic and extrinsic patient

Importance: In previous studies, this group has reported that cultured human fibroblasts suspended in hyaluronic acid (HA) filler might have potential use as a long-lasting injectable soft-tissue filler. However, the data were insufficient to determine the long-term outcomes.

Objective: To evaluate the long-term outcomes of cultured human fibroblasts suspended in HA filler used for soft-tissue augmentation.

Design, setting, and participants: A long-term case series study was performed. Between January 2010 and December 2013, a total of 38 patients were treated with fibroblast-HA filler mixture to augment nasal dorsa, nasolabial folds, and cheek depressions. Of these 38 patients, patients with follow-up period of greater than 3 years were included in this study. A total of 22 patients met the inclusion criteria.

Main outcomes and measures: Subjective assessment was performed to evaluate degree and time of resorption, improvement, satisfaction, softness of injection sites, and willingness to recommend this treatment to others. Objective assessment was carried out with patients' photographs. Safety and tolerability were also evaluated for this treatment.

Results: Of the 22 patients included in this study, 19 were women; mean (SD) patient age was 43 (15) years. All 22 patients experienced improvement following the treatment. Twenty (91%) patients were satisfied with the treatment. Nineteen patients (86%) considered that the injection site was as soft as it was before treatment. Patients' mean (SD) grading of improvement, satisfaction, and softness were 4.50 (0.51) (95% CI, 4.27-4.73), 4.14 (0.71) (95% CI, 3.82-4.45), and 4.82 (0.50) (95% CI, 4.59-5.00) at the last visit, respectively. Objective assessment demonstrated postoperative improvement in all patients: a rating of "much improved" was given to 7 patients (32%) by investigator 1; 8 patients (36%) by investigator 2; and 12 patients (55%) the injecting physician. This treatment was well tolerated; no adverse event was recorded for any patient.

Conclusions and relevance: Injection of cultured human fibroblasts suspended in HA filler might be successful for long-term soft-tissue augmentation. To our knowledge, this study represents the longest follow-up study of soft-tissue augmentation with a fibroblast-HA filler mixture to date.

Importance: Paramedian forehead flaps are commonly used to reconstruct facial defects caused by skin cancers. Data are lacking on the complications from this procedure, postoperative outcomes, and association of cancer diagnosis with rate of deep venous thrombosis (DVT).

Objectives: The primary objective was to determine complication rates after paramedian forehead flap reconstruction for defects resulting from resection of facial cancers; and the secondary objective was to determine patient factors and complications that are associated with readmission.

Design, setting, and participants: Retrospective cohort study of patients who underwent paramedian forehead flap reconstruction for skin cancer reconstruction from January 1, 2007, through December 31, 2013. Data analysis took place between October 1, 2017, and June 1, 2018.

Main outcomes and measures: Complication rates including DVT, emergency department visits, and hospital readmissions.

Results: A total of 2175 patient were included in this study; mean (SD) age, 70.3 (13.4) years; 1153 (53.5%) were men. Postoperative DVT occurred in 10 or fewer patients (≤0.5%); postoperative bleeding in 30 (1.4%), and postoperative infection in 63 (2.9%). Most patients went home on the day of surgery (89.6%; n = 1949), while 10.4% stayed one or more days in the hospital (n = 226). Overnight admission was associated with tobacco use (odds ratio [OR], 1.65; 95% CI, 1.11-2.44), hypothyroidism (OR, 1.93; 95% CI, 1.10-3.39), hypertension (OR, 1.82; 95% CI, 1.29-2.57), ear cartilage graft (OR, 2.20; 95% CI, 1.51-3.21), and adjacent tissue transfer (OR, 1.88; 95% CI, 1.33-2.67). Risk factors strongly associated with immediate return to the emergency department or readmission within 48 hours of surgery included postoperative bleeding (OR, 13.05; 95% CI, 4.24-40.16), neurologic disorder (OR, 4.11; 95% CI, 1.12-15.09), and alcohol use (OR, 7.70; 95% CI, 1.55-38.21).

Conclusions and relevance: In this study, the most common complication of paramedian forehead flap reconstruction was infection. Risk factors for readmission included development of postoperative bleeding, having a neurologic disorder, and alcohol use. Deep venous thrombosis was a rare complication. Because bleeding is a more common complication in this patient population, discretion should be used when deciding to administer anticoagulation medication to low- to medium-risk patients prior to surgery.
