Botulinum toxin A treatment in facial palsy synkinesis: a systematic review and meta-analysis.

BACKGROUND: Synkinesis is defined as involuntary movements accompanying by voluntary movements and can occur during the aftermath of peripheral facial palsy, causing functional, aesthetic and psychological problems in the patient. Botulinum toxin A (BTX-A) is frequently used as a safe and effective treatment; however, there is no standardized guideline for the use of BTX-A in synkinesis. The purpose of this article is to review and summarize studies about the BTX-A treatment of synkinesis in patients with a history of peripheral facial palsy; including given dosages, injection sites and time intervals between injections. MATERIALS AND METHODS: A multi-database systematic literature search was performed in October 2020 using the following databases: Pubmed, Embase, Medline, and The Cochrane Library. Two authors rated the methodological quality of the included studies independently using the 'Newcastle-Ottawa Quality Assessment Scale' for non-randomised studies' (NOS). RESULTS: Four-thousand-five-hundred-and-nineteen articles were found of which 34 studies met the inclusion criteria, in total comprising 1314 patients. Most studies were assessed to be of 'fair' to 'good' methodological quality. The Cohen's kappa (between author FJ and AS) was 0.78. Thirty-one studies investigated the reported dosage injected, 17 studies reported injection location and 17 studies investigated time intervals. A meta-analysis was performed for three studies comprising 106 patients, on the effects of BTX-A treatment on the Synkinesis Assessment Questionnaire (SAQ) scores. The mean difference was 11.599 (range 9.422-13.766), p < 0.01. However, due to inconsistent reporting of data of the included studies, no relationship with the dosage and location could be assessed. CONCLUSIONS: Many treatment strategies for synkinesis exist, consisting of varying BTX-A brands, dosages, time intervals and different injection locations. Moreover, the individual complaints are very specific, which complicates creating a standardized chemodenervation treatment protocol. The BTX-A treatment of long-term synkinesis is very individual and further studies should focus on a patient-tailored treatment instead of trying to standardize treatment.

Update on the role of antiseptics in the management of chronic wounds with critical colonisation and/or biofilm.

Biofilms play a major role in delaying chronic wounds from healing. A wound infiltrated with biofilm, or "critically colonised" wound, may become clinically infected if the number of microbes exceeds a critical level. Chronic wound biofilms represent a significant treatment challenge by demonstrating recalcitrance towards antimicrobial agents. However, a "window of opportunity" may exist after wound debridement when biofilms are more susceptible to topical antiseptics. Here, we discuss the role of antiseptics in the management of chronic wounds and biofilm, focusing on povidone-iodine (PVP-I) in comparison with two commonly used antiseptics: polyhexanide (PHMB) and silver. This article is based on the literature reviewed during a focus group meeting on antiseptics in wound care and biofilm management, and on a PubMed search conducted in March 2020. Compared with PHMB and silver, PVP-I has a broader spectrum of antimicrobial activity, potent antibiofilm efficacy, no acquired bacterial resistance or cross-resistance, low cytotoxicity, good tolerability, and an ability to promote wound healing. PVP-I represents a viable therapeutic option in wound care and biofilm management, with the potential to treat biofilm-infiltrated, critically colonised wounds. We propose a practical algorithm to guide the management of chronic, non-healing wounds due to critical colonisation or biofilm, using PVP-I.

Evaluation of the role of povidone­iodine in the prevention of surgical site infections.

Background: The occurrence of surgical site infections (SSIs) is associated with increased risk of mortality, development of other infections, and the need for reintervention, posing a significant health burden. The aim of this review was to examine the current data and guidelines around the use of antiseptic povidone­iodine (PVP-I) for the prevention of SSIs at each stage of surgical intervention. Methods: A literature search for selected key words was performed using PubMed. Additional papers were identified based on author expertise. Results: Scientific evidence demonstrates that PVP-I can be used at every stage of surgical intervention: preoperative, intraoperative, and postoperative. PVP-I is one of the most widely used antiseptics on healthy skin and mucous membranes for preoperative surgical site preparation and is associated with a low SSI rate. For intraoperative irrigation, aqueous PVP-I is the recommended agent and has been demonstrated to decrease SSIs in a range of surgical settings, and for postoperative wound healing, there is a growing body of evidence to support the use of PVP-I. Conclusions: There is a need for more stringent study designs in clinical trials to enable meaningful comparisons between antiseptic agents, particularly for preoperative skin preparation. The use of a single agent (PVP-I) at each stage of surgical intervention could potentially provide advantages, including economic benefits, over agents that can only be used at discrete stages of the surgical procedure. Key message: Evidence supports the use of PVP-I at all stages of surgical intervention, from preoperative measures (including skin preparation, preoperative washing, and nasal decolonization) to intraoperative irrigation, through to postoperative wound management. However, there is a need for more stringent study designs in clinical trials to enable meaningful comparisons between antiseptic agents, particularly for preoperative skin preparation.

Psychological counselling in patients with a peripheral facial palsy: initial experience from an expert centre.

BACKGROUND: The aims of this pilot study were to evaluate the psychologist's role on the multidisciplinary team during peripheral facial palsy (PFP) patient care and to identify the potential predictors of anxiety and depressive symptoms/disorders in PFP patients. METHODS: Using the prospective non-controlled study design, PFP patients aged 18-75 years who presented to the Radboud Facial Palsy Expert Centre, the Netherlands, were enrolled during a 1-year interval. The main outcome variables were 1) anxiety and depression in relation to PFP using the Hospital Anxiety and Depression Scale (HADS) and 2) the outcome of psychological counselling in patients with a HADS score ≥ 8. RESULTS: A sample comprised 25 patients (68% females, 56% right-side PFP, 16% House-Brackmann scale I-II) with a mean age of 50 ± 14 years were referred to a psychologist. The proportion of patients with a HADS score ≥8, were 16 (64%) and 13 (52%), respectively. Especially, coping (in general or coping with the disease, 48%) and/or help with the choice of possible surgery (8.0%) were important reasons for counselling. In one case, a patient had chronic fatigue syndrome and was therefore referred to a psychological specialist centre. One patient was treated with acceptance and commitment therapy (ACT) with good results. CONCLUSIONS: Despite a small sample size and limited statistical analyses, the results of this study suggest that one-eighth of the PFP patients require psychological evaluation and treatments. This pilot study emphasises the important role of psychological screening and counselling in PFP patient care.

Cosmetic appreciation and emotional processing in patients with a peripheral facial palsy: A systematic review.

Background; The goal of this review is 1) to summarize the studies assessing PFP by casual observers, patients themselves and the cosmetic appreciation of the PFP and 2) to summarize the studies assessing whether there is a difference in emotional recognition/processing of facial emotions and/or cognitive tasks in patients with a PFP. Materials and Methods; A multi-database systematic literature search was performed using the following databases: Pubmed, Embase, Medline, and The Cochrane Library from the earliest date of each database up to December 2019. Population of interest consisted of patients with a PFP and studies that investigated cosmetic appreciation and/or emotional recognition and/or emotional processing in these patients. Two authors rated the methodological quality of the included studies independently using the 'Newcastle - Ottawa Quality Assessment Scale' for nonrandomised studies' (NOS). Two authors extracted the outcome data regarding cosmetic appreciation and/or emotional recognition/processing from the included studies. Results; Twelve hundred and thirty-two studies were found of which eleven studies met the inclusion criteria. Most studies were assessed to be of 'fair' to 'good' methodological quality. The Cohen's kappa (between author RL and SP) was 0.68. Two studies investigated emotional processing and/or emotional recognition. Nine studies investigated cosmetic appreciation in both patients and casual observers. Important findings of this systematic review are that there is a correlation between the perceived severity of the PFP of the patients and the ratings by casual observers. Secondly there seems to be a laterality difference in cosmetic appreciation and thirdly there might to be a decreased emotional recognition and processing in patients with a PFP. Conclusion; Emotional recognition and cosmetic appreciation in patients with a PFP is an under investigated area, in which further studies are needed to substantiate the findings in current literature.

Association between duration of peripheral facial palsy, severity, and age of the patient, and psychological distress.

BACKGROUND: Peripheral facial palsy (PFP) (paralysis) can be a devastating condition that has been shown to have associations with increased depression and worse quality of life. The aim of the present study is to better understand the complex association of psychological distress with the duration, severity, and age of patients with PFP. We hypothesize that a shorter duration of PFP is associated with higher levels of psychological distress. METHODS: Fifty-nine patients with PFP that existed longer than 3 months were included in this study. The Hospital Anxiety and Depression Scale (HADS) was used to assess the presence and severity of anxiety and depressions. Spearman's correlation analysis was used to determine correlation between psychological distress, duration, severity of the PFP, and age. RESULTS: Fifty-nine patients were included in this study, of whom 22 were male and 37 were female. The mean age was 55.6 ±â€¯14.6 years and mean duration of PFP from onset ranged from 3 months to 35 years (with a mean duration of 5.39 ±â€¯6.06 years). Twenty-eight patients had left-sided PFP, 30 patients had right-sided PFP, and one patient had bilateral PFP. The majority were caused by Bell's palsy (50.8%). In the group with a duration less than 5 years, there were five (12.8%) patients having a score between 11 and 15 (on HADS) compared to two (10%) patients in the group with a duration of 5 years or more(p = 0.04). CONCLUSION: There seems to be an association between moderate depression and duration of the PFP. Further studies need to substantiate our findings.

A closer look at the paralyzed face; a narrative review of the neurobiological basis for functional and aesthetic appreciation between patients with a left and a right peripheral facial palsy.

BACKGROUND: The facial nerve or n. facialis (NVII) is the seventh cranial nerve and it is responsible for the innervation of the mimic muscles, the gustatory organ, and the secretomotor function to the salivary, lacrimal, nasal and palatine glands. Clinical presentation of Facial Palsy (FP) is characterized by unilateral facial asymmetry and may present with a change in taste, decreased saliva production, and dysarthria. A facial palsy has a notable effect on the facial appreciation by both the patient and the environment and also affects quality of life and emotional processing. There appear to be differences in the appreciation of people with a left and right facial palsy. PURPOSE OF THIS REVIEW: The purpose of the review is to give an overview of the anatomy of the facial nerve, neuro-anatomy of face processing, and hemispheric specialization and lateralization. Further,an overview is given of the clinical studies that translated the neuro-anatomical and neurobiological basis of these concepts into clinical studies. What this review adds: This review emphasizes the neurobiological evidence of differences in face processing between the left and right cerebral hemisphere, wherein it seems that the right hemisphere is superior in emotional processing. Several theories are proposed; 1) a familiarity hypothesis and 2) a left-right hemispheric specialization hypothesis. In clinical studies, promising evidence might indicate that, in patients with FP, there is indeed a difference in how left and right FP are perceived. This might give differences in decreased quality of life and finally in occurrence of depression. Further research must aim to substantiate these findings and determine the need for altering the standard therapeutic advice given to patients.

The modified Fitzpatrick Wrinkle Scale: a clinical validated measurement tool for nasolabial wrinkle severity assessment.

BACKGROUND: The number of existing wrinkle assessment scales makes it difficult to compare the efficacy of cosmetic techniques in rejuvenating photoaged skin. A single and simple assessment scale that reliably quantifies wrinkle depth is needed. OBJECTIVE: The objective was to validate the Modified Fitzpatrick Wrinkle Scale (MFWS) as a nasolabial wrinkle severity assessment tool. METHODS AND MATERIALS: The MFWS comprises three main classes, in which definitions are based on a set of reference photographs and descriptions, and three interclasses, in which definitions are based only on descriptions. Assessors were trained to apply this scale to volunteers and study patients by using photographs of nasolabial wrinkles either alone or with descriptions. Inter- and intraassessment reliability coefficients were calculated using weighted kappa statistics. RESULTS: In patients, the combined intraassessor reliability from both sides of the face was 0.71 (95% confidence interval [CI], 0.68-0.74) when only photographs were used and 0.79 (95% CI, 0.76-0.82) when descriptions were added. Interassessor reliability for the photographs alone was 0.65 (95% CI, 0.62-0.68) and 0.74 (95% CI, 0.69-0.79) for photographs plus descriptions. CONCLUSIONS: The MFWS is a reliable method for quantitative assessment of nasolabial skin folds, with good inter- and intraassessor reliability. Including descriptions with the photographs increased reliability.

Chest Surgery for Transgender and Gender Nonconforming Individuals.

Chest surgery can greatly facilitate the experience of living in a gender role. For transfeminine chest surgery, most surgeons recommend a 12-month period of feminizing hormone therapy prior to breast augmentation. For those who already have some breast volume due to hormone treatment, lipofilling can be a good option. Transmasculine chest surgery includes mastectomy and creation of a male chest. Preoperative parameters to be evaluated include breast volume, degree of excess skin, nipple-areola complex size and position, and skin elasticity. The algorithm the authors developed and modified can help choose from 5 techniques, resulting in an aesthetically pleasing male chest.

Male-to-Female Gender Confirmation Surgery: Intestinal Vaginoplasty.

The major steps in vaginoplasty are orchiectomy, penile amputation, creation of the neovaginal cavity with lining, and reconstruction of urethral meatus, labia, and clitoris. During pedicled intestinal transfer, an intestinal segment is transferred in a dissected cavity between the bladder and rectum. The bowel harvest is performed by a total laparoscopic technique. It is imperative to create the labia majora and minora, the clitoris, and a clitoral hood to achieve the physiologic and aesthetic equivalent of female external genitalia. Intestinal vaginoplasty seems to be associated with a low rate of adverse events. Life-long vaginal hygiene and dilatation is recommended.

Perforator flap terminology: update 2002.

The first terminology consensus on perforator flaps, reached in 2001, was reviewed and further simplified following the Sixth International Course on Perforator Flaps.

Soft tissue reconstruction with the superior gluteal artery perforator flap.

The development of the perforator flap technique revolutionized the practice of soft tissue transfer. The main goal of this technique is muscle sparing at the donor site for function and strength. Meanwhile, this concept is being widely applied for reconstruction of tissues throughout the entire body. Perforator flaps are the ultimate upgrade of the well-known myocutaneous flaps. Theoretically, any myocutaneous flap can be harvested as a perforator flap if skin resurfacing is needed. Although the DIEP flap, the anterolateral thigh flap, and the TAP flap are probably more frequently used for breast, trunk, and upper and lower limb reconstruction, as well as head and neck reconstruction, the SGAP flap takes its own position in the large group of perforator flaps and has its own specific indications.

Validity of a structured method of selecting abstracts for a plastic surgical scientific meeting.

In 1999, the European Association of Plastic Surgeons accepted a structured method to assess and select the abstracts that are submitted for its yearly scientific meeting. The two criteria used to evaluate whether such a selection method is accurate were reliability and validity. The authors previously established this method to be reliable on the basis of a prospective evaluation of the selection process used for the 2000 meeting of the European Association of Plastic Surgeons. It is more difficult to assess the validity of this method because there is no objective standard of quality of a scientific abstract against which the accuracy of selection can be assessed. This study statistically evaluated the accuracy of the meeting participants' assessment of presentations made during the meeting as the criterion standard for abstract selection on the basis of data obtained from the 2002 selection process. The authors evaluated the interobserver repeatability among five meeting participants of selecting the best presentations, the validity of the method of abstract selection after this criterion standard had been established, and the validity of reviewers' rating of abstracts as indicators of the scientific value of the actual presentations. The authors conclude that the assessment of platform presentations at a plastic surgical meeting is reliable. Accepting this assessment as the criterion standard, however, they could not prove the validity of their selection method or the validity of the reviewers' rating of abstracts as an indicator of the scientific value of the actual presentations.

The "Gent" consensus on perforator flap terminology: preliminary definitions.

Due to its increasing popularity, more and more articles on the use of perforator flaps have been reported in the literature during the past few years. Because the area of perforator flaps is new and rapidly evolving, there are no definitions and standard rules on terminology and nomenclature, which creates confusion when surgeons try to communicate and compare surgical techniques. This article attempts to represent the opinion of a group of pioneers in the field of perforator flap surgery. This consensus was reached after a terminology consensus meeting held during the Fifth International Course on Perforator Flaps in Gent, Belgium, on September 29, 2001. It stipulates not only the definitions of perforator vessels and perforator flaps but also the correct nomenclature for different perforator flaps. The authors believe that this consensus is a foundation that will stimulate further discussion and encourage further refinements in the future.

Sex Reassignment Surgery in the Female-to-Male Transsexual.

In female-to-male transsexuals, the operative procedures are usually performed in different stages: first the subcutaneous mastectomy which is often combined with a hysterectomy-ovarectomy (endoscopically assisted). The next operative procedure consists of the genital transformation and includes a vaginectomy, a reconstruction of the horizontal part of the urethra, a scrotoplasty and a penile reconstruction usually with a radial forearm flap (or an alternative). After about one year, penile (erection) prosthesis and testicular prostheses can be implanted when sensation has returned to the tip of the penis. The authors provide a state-of-the-art overview of the different gender reassignment surgery procedures that can be performed in a female-to-male transsexual.
