Gravity in Midfacial Aging: A 3-Dimensional Study.

BACKGROUND: Volume loss and volume descent are complementary aspects of facial aging, although the respective contribution of each is unclear. OBJECTIVES: The aim of this study was to quantify in 3 dimensions the effects of gravity on the midface in both upright and supine positions in an older and a younger group of patients. METHODS: A prospective study was undertaken of 53 female patients who had not undergone treatment with dermal fillers or facial cosmetic surgery. Three-dimensional photography with a VECTRA H1 camera (Canfield Scientific, Fairfield, NJ) was taken in supine and sitting positions. Volume shifts and displacement of structures in 3 dimensions were measured and analyzed. RESULTS: Morphologically, upon shifting from sitting to supine position, the tail of the brow elevated, the tear trough filled, the buccal and malar fat shifted posteriosuperiorly, the earlobe decreased in height, the nasiolabial folds and marionette lines diminished, the modiolus shifted laterally, and the jowl diminished. Volumetric analysis revealed that the infraorbital region increased in volume by a mean [SD] of 0.59 [0.55] mL, the tear trough by 0.22 [0.19] mL, and the malar region by 1.2 [1.06] mL. With subjects in the supine position, all facial topographic landmarks displaced significantly from sitting position. CONCLUSIONS: Facial aging in this cohort was predominantly due to tissue descent rather than volume loss. Reversal of the gravitational force restores the 3D position of the facial subunits and leads to volumization in desirable locations that approximates a more youthful appearance. The volume restored via redistribution of facial fat is comparable to that typically injected during direct volume transfer procedures.

Tongue symptoms, suspension force and duration during operative laryngoscopy.

PURPOSE: Suspension laryngoscopy is a commonly performed procedure in otolaryngology. During the procedure, the laryngoscope applies direct force to the tongue. Postoperative tongue symptoms include pain, swelling, numbness, taste disturbance, and rarely motor deficits. Duration and magnitude of force applied have previously been associated with post-operative throat and tongue pain, respectively. We sought to correlate postoperative tongue symptoms with magnitude of force applied and/or duration of suspension and investigate any risk factors for tongue morbidity. MATERIALS AND METHODS: A sample of patients undergoing suspension laryngoscopy between 2015 and 2018 were prospectively recruited. Those with preexisting tongue symptoms, disease or surgery were excluded. Patients completed preoperative and postoperative questionnaires evaluating tongue swelling, numbness, motion and taste disturbance. Symptoms were subjectively scored on a visual scale from 0 to 10. Patient demographics, past medical and social history were also recorded. Intraoperative pressures were measured using a spring force scale, positioned between the suspension arm and Mayo stand. Initial and end suspension forces and duration of suspension were recorded. RESULTS: 120 patients met inclusion criteria, of which 63 completed both preoperative and postoperative questionnaires. 6 patients (9.5%) experienced postoperative tongue symptoms. Suspension force and duration of suspension were not significantly predictive of postoperative tongue symptoms. While all symptomatic patients were current or former cigarette smokers, smoking status was not found to be a statistically significant factor. CONCLUSIONS: Neither suspension forces nor duration of suspension were predictive of postoperative tongue morbidity. Further research is needed to evaluate the role of smoking status on postoperative tongue symptoms.

Investigation of the Longevity of the Endoscopic Midface Lift.

IMPORTANCE: To our knowledge, until now, the efficacy and durability of the transtemporal endoscopic preperiosteal midface lift has not been reported in the literature. OBJECTIVE: To determine the efficacy and longevity of the endoscopic preperiosteal midface lift using objective measurements and validated aesthetic scales. DESIGN, SETTING, AND PARTICIPANTS: This retrospective review included patients 18 years or older who were treated for aging midface by endoscopic midface lift by the senior author (A.E.W.) between June 2000 and August 2016. Patients were categorized based on length of follow-up into 3 groups: (1) short-term (1-3 years), (2) intermediate-term (3-5 years), and (3) long-term (>5 years). INTERVENTIONS OR EXPOSURES: Endoscopic preperiosteal midface lift. MAIN OUTCOMES AND MEASURES: (1) Objective measurements of midfacial height (the width of the interzygomatic distance of the midface to the medial canthus [WIZDOM-MC]), (2) validated regional aesthetic scales, and (3) global aesthetic scoring systems measured preoperatively, 3 to 6 months postoperatively, and at the most recent follow-up visit. RESULTS: Adult patients 18 years or older (median [range] age, 59 [31-79] years) who were treated for aging midface by undergoing an endoscopic midface lift were included in this study. The medical records of 143 patients were reviewed (135 women and 8 men). The endoscopic midface lift resulted in objective improvement in midfacial height. The median WIZDOM-MC decreased by 3.4 mm after the endoscopic midface lift (interquartile range [IQR], 2.3-4.4 mm; P < .001), thus shortening the elongated lower eyelid. At 5 to 15 years after surgery, there was a sustained decrease in median WIZDOM-MC of 2.1 mm (IQR, 0.8-3.1 mm; P < .001). Improvement in the infraorbital hollow was also sustained in patients at more than 5 years' follow-up (IQR, 0-1.0; P < .001). Improvements in upper cheek fullness and lower cheek fullness were maintained at 3 to 5 years and tended to be at baseline at more than 5 years. Global aesthetic improvement scores remained significantly improved at 5 to 15 years' follow-up. CONCLUSIONS AND RELEVANCE: There is a significant, objective improvement in midfacial height after the endoscopic midface lift that persists for up to 15 years. Validated midfacial scales and global aesthetic scoring systems demonstrate sustained improvement in midface appearance over time. Surgery that minimally disrupts the zygomatic and orbicularis retaining ligaments can provide long-lasting aesthetic improvements. LEVEL OF EVIDENCE: 4.

Psychology of the Facelift Patient.

This paper presents an extensive literature review of the psychology of facelift patients as it has evolved over the past 50 years. Earlier studies revealed significant levels of pre and perioperative depression. Facelift patients generally exhibit emotional and social concerns about facial appearance that are higher than the general population. Many are undergoing midlife situational stresses and may lack the positive characteristics to deal with them. The most common diagnoses seen include depression, impulsivity, unstable personality, and passive dependence, albeit not necessarily serious. Improvement in body image is the major driver for surgery. Characteristics of female patients as defined by their age are described. These include the younger emotionally dependent group, the worker group of middle age, and the older grief group. Male patients are seen to have a higher level of psychological dysfunction, but a higher improvement in postoperative quality of life. Motivations for surgery include increasing self-esteem, making new friends, improving relationships, and getting better jobs. Overall patient satisfaction is more than 95%, with improvement seen in positive changes in their life, increased self-confidence and self-esteem, decreased self-consciousness about their appearance, and overall improvement in quality of life. Postoperative psychological reactions are seen in about half the patients, these primarily being anxiety and depression of varying degrees. Predictors of patient satisfaction include the desire for self-image improvement in contradistinction to a change in life situation. Negative predictors include male sex, young age, unrealistic expectations, relationship disturbances, and preexisting psychological pathology. The importance of good patient selection in achieving a satisfied patient is outlined and emphasized.

EGFR and RB1 as Dual Biomarkers in HPV-Negative Head and Neck Cancer.

Clinical decision making for human papillomavirus (HPV)-negative head and neck squamous cell carcinoma (HNSCC) is predominantly guided by disease stage and anatomic location, with few validated biomarkers. The epidermal growth factor receptor (EGFR) is an important therapeutic target, but its value in guiding therapeutic decision making remains ambiguous. We integrated analysis of clinically annotated tissue microarrays with analysis of data available through the TCGA, to investigate the idea that expression signatures involving EGFR, proteins regulating EGFR function, and core cell-cycle modulators might serve as prognostic or drug response-predictive biomarkers. This work suggests that consideration of the expression of NSDHL and proteins that regulate EGFR recycling in combination with EGFR provides a useful prognostic biomarker set. In addition, inactivation of the tumor suppressor retinoblastoma 1 (RB1), reflected by CCND1/CDK6-inactivating phosphorylation of RB1 at T356, inversely correlated with expression of EGFR in patient HNSCC samples. Moreover, stratification of cases with high EGFR by expression levels of CCND1, CDK6, or the CCND1/CDK6-regulatory protein p16 (CDKN2A) identified groups with significant survival differences. To further explore the relationship between EGFR and RB1-associated cell-cycle activity, we evaluated simultaneous inhibition of RB1 phosphorylation with the CDK4/6 inhibitor palbociclib and of EGFR activity with lapatinib or afatinib. These drug combinations had synergistic inhibitory effects on the proliferation of HNSCC cells and strikingly limited ERK1/2 phosphorylation in contrast to either agent used alone. In summary, combinations of CDK and EGFR inhibitors may be particularly useful in EGFR and pT356RB1-expressing or CCND1/CDK6-overexpressing HPV-negative HNSCC.

Long-term Results of Endoscopically Assisted Pediatric Cholesteatoma Surgery.

OBJECTIVE: Routine endoscopic examination during primary surgery decreased the rate of residual cholesteatoma to 18% in our early experience. Based on this, we stopped performing routine second-look surgery in children who were endoscopically free of cholesteatoma at the end of primary surgery. We sought to investigate if second-look procedures after endoscopic-assisted surgery could safely be performed only in children at a high risk of residual disease (extensive inflammation, spontaneously ruptured or fragmented cholesteatoma, residual disease intentionally left). STUDY DESIGN: Case series with chart review. SETTING: Tertiary pediatric otolaryngology practice. SUBJECTS AND METHODS: Children aged 1 to 16 years who were treated for cholesteatoma over 15-year period by a single surgeon. Extent of disease and endoscopic findings were compared with rates of residual disease. Time to diagnosis of residual disease and prognostic factors were analyzed. RESULTS: Forty-two children underwent endoscopically assisted middle ear surgery for cholesteatoma. Of 42 children, 7 (17%) had additional disease found by endoscopy that was missed by microscopy alone. Twelve children at high risk had second looks; 5 (42%) had residual disease. Of 30 children, 2 (7%) presented with macroscopically evident residual cholesteatoma after no planned second look on office follow-up and subsequently underwent reoperation and were cured. CONCLUSIONS: Selective second-look surgery in high-risk children did not adversely affect outcome as compared with the low-risk group. Cholesteatoma was identified endoscopically in 7 of 42 (17%) children thought to be microscopically free of disease at initial surgery. The endoscope may aid in visualization of difficult middle ear recesses when used to complement microscopy. Further investigation with multicenter data is needed.

Predicting white matter targets for direct neurostimulation therapy.

A novel depth electrode placement planning strategy is presented for propagating current to distant epileptic tissue during direct neurostimulation therapy. Its goal is to predict optimal lead placement in cortical white matter for influencing the maximal extent of the epileptic circuit. The workflow consists of three fundamental techniques to determine responsive neurostimulation depth lead placement in a patient with bilaterally independent temporal lobe epileptogenic regions. (1) Pre-implantation finite element modeling was used to predict the volume of cortical activation (VOCA). This model estimated the electric field and neural tissue influenced surrounding two adjacent active depth contacts prior to implantation. The calculations included anticipated stimulation parameters. (2) Propagation of stimulation therapy was simulated pre-implantation using the VOCA model positioned in the subject's diffusion tensor imaging (DTI) determined 8h post-ictally compared to an interictal DTI. (3) Validation of the predicted stimulated anatomical targets was determined 4.3 months post-implantation using subtracted activated SPECT (SAS). Presurgically, the modeling system predicted white matter connectivity and visual side-effects to stimulation. Post-implantation, SAS validated focal blood flow changes in ipsilateral occipital and frontal regions, and contralateral temporal lobe. This workflow demonstrates the feasibility of planning white matter-electrode placement with individual specificity to predict propagation of electrical current throughout an epileptic circuit.
