Targeted chemodenervation of the posterior belly of the digastric muscle for the management of jaw discomfort in facial synkinesis.

BACKGROUND: Botulinum toxin (BT-A) chemodenervation has been proved to significantly improve the physical and psychological well-being of patients suffering from facial synkinesis. Despite this, a cohort of patients has persistent tightness and discomfort around the angle of the jaw, which may be caused by synkinesis within the posterior belly of digastric (PBD) muscle. This study was designed to evaluate the benefits of ultrasound-guided BT-A injections into the PBD. METHODS: Thirty-three patients with recalcitrant tightness and discomfort around the angle of the jaw, despite maximal facial therapy and platysmal chemodenervation were selected for inclusion. Patients underwent ultrasound-guided BT-A injection into the ipsilateral PBD muscle (skin puncture site 1 cm inferior and posterior to the angle of mandible). Outcomes consisted of the Facial Disability Index (FDI), Synkinesis Assessment Questionnaire (SAQ), and a visual analogue scale (VAS) designed to assess tightness and pain around the PBD when moving the jaw, swallowing, and masticating. Questionnaires were completed two weeks before and postinjection. Statistical analysis was performed using a paired t-test. RESULTS: Nineteen patients completed the post-treatment outcome questionnaire. A statistically significant improvement was noted in the physical and social function aspects of the FDI and all aspects of the patient-reported VAS scores apart from tightness and pain on jaw retrusion and swallowing. There was no significant difference in the SAQ. CONCLUSION: This study has demonstrated the patient-perceived benefit of ultrasound-targeted BT-A chemodenervation of PBD. This represents a low-risk treatment option that can be easily added to the repertoire of treatments offered to patients with post paralysis facial synkinesis.

Revisiting the Direct Brow Lift in Patients With Facial Palsy: 4 Key Modifications.

PURPOSE: The direct brow lift is a simple and popular technique, particularly in patients with brow ptosis secondary to facial palsy. It provides a high degree of control in determining the degree of brow elevation and shape achieved. However, it is arguably the least debated in terms of addressing some of its sequelae, namely the risks of a visible or indrawn scar and forehead paraesthesia. In this article, we report outcomes using four alternative principles to those outlined in current published literature. METHODS: All patients undergoing a primary direct brow lift for brow ptosis secondary to facial palsy between January 2015 and December 2019 under a single surgeon (R.M.) were included in the study. The technical refinements of the procedure included a W-plasty type stealth skin incision, counter-bevelling of the upper and lower incision lines, skin excision in the subcutaneous plane only with minimal excision of fat and browpexy to the frontal periosteum through small linear puncture incisions in the frontalis. RESULTS: A total of 23 patients undergoing 24 direct brow lifts were included in the study. The mean follow-up was 1.3 years (range 0.5-3 years). No patients reported postoperative forehead paraesthesia or brow alopecia. One patient required a further temporal browlift 15 months later. Brow height was rated excellent (0-1.5 mm difference) in 71% of brows and good (1.6-4.9 mm difference) in 14% of brows. The average Manchester scar scale was 8.6/28. CONCLUSION: The technical modifications presented substantially reduce the rates of postoperative paraesthesia, whilst achieving satisfactory aesthetic outcomes.

An International Collaborative Standardizing Patient-Centered Outcome Measures in Pediatric Facial Palsy.

IMPORTANCE: Standardization of outcome measurement using a patient-centered approach in pediatric facial palsy may help aid the advancement of clinical care in this population. OBJECTIVE: To develop a standardized outcome measurement set for pediatric patients with facial palsy through an international multidisciplinary group of health care professionals, researchers, and patients and patient representatives. DESIGN, SETTING, AND PARTICIPANTS: A working group of health care experts and patient representatives (n = 21), along with external reviewers, participated in the study. Seven teleconferences were conducted over a 9-month period between December 3, 2016, and September 23, 2017, under the guidance of the International Consortium for Health Outcomes Measurement, each followed with a 2-round Delphi process to develop consensus. This process defined the scope, outcome domains, measurement tools, time points for measurements, and case-mix variables deemed essential to a standardized outcome measurement set. Each teleconference was informed by a comprehensive review of literature and through communication with patient advisory groups. Literature review of PubMed was conducted for research published between January 1, 1981, and November 30, 2016. MAIN OUTCOMES AND MEASURES: The study aim was to develop the outcomes and measures relevant to children with facial palsy as opposed to studying the effect of a particular intervention. RESULTS: The 21 members of the working group included pediatric facial palsy experts from 9 countries. The literature review identified 1628 papers, of which 395 (24.3%) were screened and 83 (5.1%) were included for qualitative evaluation. A standard set of outcome measurements was designed by the working group to allow the recording of outcomes after all forms of surgical and nonsurgical facial palsy treatments among pediatric patients of all ages. Unilateral or bilateral, congenital or acquired, permanent or temporary, and single-territory or multiterritory facial palsy can be evaluated using this standard set. Functional, appearance, psychosocial, and administrative outcomes were selected for inclusion. Clinimetric and psychometric outcome measurement tools (clinician-, patient-, and patient proxy-reported) and time points for measuring patient outcomes were established. Eighty-six independent reviews of the standard set were completed, and 34 (85%) of the 40 patients and patient representatives and 44 (96%) of the 46 health care professionals who participated in the reviews agreed that the standard set would capture the outcomes that matter most to children with facial palsy. CONCLUSIONS AND RELEVANCE: This international collaborative study produced a free standardized set of outcome measures for evaluating the quality of care provided to pediatric patients with facial palsy, allowing benchmarking of clinicians, comparison of treatment pathways, and introduction of value-based reimbursement strategies in the field of pediatric facial palsy. LEVEL OF EVIDENCE: NA.

A Unifying Algorithm in Microvascular Reconstruction of Oral Cavity Defects Using the Trilaminar Concept.

Although many algorithms exist to classify oral cavity defects, they are limited by either considering a single subsite or failing to provide a concise reconstructive algorithm for the breadth of defects. Based upon our experience as a tertiary referral center, a unifying algorithm is presented that guides free flap selection in this heterogenous population. METHODS: All intraoral defects requiring microvascular reconstruction from February 2012 to August 2018 were reviewed. Defects were classified according to their depth as unilaminar (type U = mucosa only), bilaminar (type B = mucosa and bone), or trilaminar (type T = mucosa, bone, and skin) and the number and side of mucosal zones involved (from 1 to 5). Hard palate defects were considered separately and excluded if part of a wider maxillectomy defect. RESULTS: A total of 118 patients were eligible for inclusion in the study. Of type U defects involving 1 mucosal zone, 98% were reconstructed with a radial forearm free flap. Ninety-two percentage of type U defects involving ≥2 mucosal zones were reconstructed with an anterolateral thigh flap. Among type B defects, 86% were reconstructed with a fibula osseocutaneous free flap if less than 4 mucosal zones were involved and 100% reconstructed with an ALT if ≥4 mucosal zones were involved. The algorithm presented was accurate for 93% of the cases. Ninety-eight percentage of patients achieved intelligible speech and 72% returned to a normal diet. Flap success rate was 100%. CONCLUSIONS: The algorithm presented provides a simple system to guide the reconstruction of oral cavity defects.

Factors that predict deep inferior epigastric perforator flap donor site hernia and bulge.

Deep inferior epigastric artery perforator (DIEP) flap has become the gold standard in autologous breast reconstruction. Attention is now being focused on the impact of DIEP flap harvest technique on abdominal hernia rates. The aim of this study was to evaluate DIEP abdominal wall morbidity in relation to flap harvest and fascial closure technique. A retrospective analysis of patients undergoing DIEP flap breast reconstruction between 2012 and 2016 was performed. Post-operative evaluation of the abdominal wall integrity was performed by an operating consultant. The rectus fascia was closed using one of three techniques. The study included 202 patients, in whom 234 DIEP flaps were performed. Eight patients (3.4%) developed a clinically evident abdominal bulge post-operatively and one (0.5%) had a hernia. Harvesting two or more perforators was more likely to result in post-operative abdominal hernia/bulge than taking a single perforator (p = .032). Using a perforator from the lateral row or both rows was more likely to result in a hernia/bulge than if a single medial perforator was harvested (p = .026). Comparison of the rectus fascia closure technique did not show any statistically significant difference in abdominal wall morbidity. Consideration should be given towards perforator selection when harvesting a DIEP flap. Where appropriate, a suitable single medial row perforator with a favourable suprafascial course should be chosen. This study has not shown mesh-free fascial closure to be inferior to mesh-supported closure. Careful consideration to the role of synthetic mesh within this patient cohort should be given.

Preserving a patent DIEP pedicle to facilitate salvage breast reconstruction with a second free flap: A case report.

Surgeons performing free flap breast reconstruction need to have a range of techniques in their armamentarium to successfully salvage cases of flap failure. We present a case of 47-year-old patient who suffered near-total right breast deep inferior epigastric perforator (DIEP) flap failure 3 days post-bilateral immediate breast reconstruction with DIEP flaps. At debridement, the DIEP pedicle was noted to be patent with preserved perfusion to a small segment of tissue around the origin of the pedicle. This tissue and the DIEP pedicle itself were therefore preserved to facilitate subsequent breast reconstruction using stacked transverse upper gracilis flaps anastomosed end-to-end to the original DIEP pedicle. Post-operatively, both flaps remained viable with no further complications and symmetrical aesthetic result maintained at 2 months follow-up post-salvage procedure. This case emphasizes the importance of exercising caution during initial debridement for free flap failure to preserve viable tissue in the flap and pedicle, particularly in circumstances where vascular flow in the pedicle is maintained, to facilitate successful salvage reconstruction.

Facial palsy: what can the multidisciplinary team do?

The functional and psychosocial impact of facial paralysis on the patient is significant. In response, a broad spectrum of treatment options exist and are provided by a multitude of health care practitioners. The cause and duration of the facial weakness can vary widely and the optimal care pathway varies. To optimize patient outcome, those involved in the care of patients with facial palsy should collaborate within comprehensive multidisciplinary teams (MDTs). At an international level, those involved in the care of patients with facial paralysis should aim to create standardized guidelines on which outcome domains matter most to patients to aid the identification of high quality care. This review summarizes the causes and treatment options for facial paralysis and discusses the subsequent importance of multidisciplinary care in the management of patients with this condition. Further discussion is given to the extended role of the MDT in determining what constitutes quality in facial palsy care to aid the creation of accepted care pathways and delineate best practice.

Predicting and planning for SIEA flap utilisation in breast reconstruction: An algorithm combining pre-operative computed tomography analysis and intra-operative angiosome assessment.

BACKGROUND: Low flap complication rates and excellent aesthetic outcomes are now commonplace in breast reconstruction. As a result, attention is now being focussed on minimising donor site morbidity. Despite its potential donor site advantages, the superficial inferior epigastric artery (SIEA) flap is often discounted, given concerns about the high flap failure rates. In this study, we present our experience of using the SIEA flap in breast reconstruction and provide an algorithm based on pre-operative computed tomography angiography (CTA) to aid pre-operative planning. METHODS: A retrospective analysis of SIEA flap breast reconstruction cases performed at our unit between 2009 and 2016 was performed and outcomes were assessed. In addition, the patients' pre-operative CTA images were assessed and compared to those of a matched group of patients who underwent deep inferior epigastric artery perforator (DIEP) flap breast reconstruction. RESULTS: Twenty-six patients who underwent SIEA flap breast reconstruction were eligible for inclusion. No flaps were lost. Donor site seroma rate was 20%. The largest SIEA diameter in those who underwent an SIEA flap was significantly larger (p = 0.0001) than in those who underwent DIEP flap breast reconstruction. Significantly more number of patients who underwent SIEA flap breast reconstruction had a SIEA diameter greater than or equal to that of the largest DIEP flap perforator (p = 0.0001) in the group where a DIEP flap was used for breast reconstruction. CONCLUSION: High success rates can be achieved with abdominal flaps based on the superficial vascular system and careful pre- and perioperative assessment of patients.

Objective sensory and functional outcomes at the donor site following endoscopic-assisted sural nerve harvest.

BACKGROUND: The sural nerve is a common choice for a nerve graft. Understanding the potential morbidity associated with its harvest is important. In this study, we describe the objective sensory and functional outcomes associated with endoscopic sural nerve harvest from a combined paediatric and adult population. METHODS: Data were collected prospectively from patients attending for follow-up between August 2015 and January 2016, who had previously undergone an endoscopic sural nerve graft harvest. Sensory loss was evaluated using a 5.07 Semmes-Weinstein monofilament. The lower extremity functional scale was used to evaluate the patients' lower limb function. Statistical comparison was made using the Student's t-test. RESULTS: The outcomes from 46 sural nerve grafts were evaluated. The mean age of the patients was 18.1 years (range 4-45 years old). The mean time since surgery was 4.3 years. Those aged ≤18 years had a significantly smaller area of sensory loss (p = 0.003), which was not related to a difference in foot size. Those who had undergone surgery >6 months previously had a significantly smaller area of sensory loss than those who had undergone surgery <6 months ago (p = 0.0002). The mean lower extremity functional scale score was 78.7/80. CONCLUSION: We demonstrated a significantly reduced post-harvest sensory deficit among a paediatric population compared to that seen in adults. Furthermore, sensory loss reduces with time. Despite the sensory loss resulting from sural nerve graft harvest, there is minimal loss of function. As such, the sural nerve continues to be an excellent donor for a nerve graft procedure.

Scar Revision Surgery: The Patient's Perspective.

BACKGROUND: Insufficient satisfaction outcome literature exists to assist consultations for scar revision surgery; such outcomes should reflect the patient's perspective. The aim of this study was to prospectively investigate scar revision patient satisfaction outcomes, according to specified patient-selection criteria. METHODS: Patients (250) were randomly selected for telephone contacting regarding scar revisions undertaken between 2007-2011. Visual analogue scores were obtained for scars pre- and post-revision surgery. Surgery selection criteria were; 'presence' of sufficient time for scar maturation prior to revision, technical issues during or wound complications from the initial procedure that contributed to poor scarring, and 'absence' of site-specific or patient factors that negatively influence outcomes. Patient demographics, scar pathogenesis (elective vs. trauma), underlying issue (functional/symptomatic vs. cosmetic) and revision surgery details were also collected with the added use of a real-time, hospital database. RESULTS: Telephone contacting was achieved for 211 patients (214 scar revisions). Satisfaction outcomes were '2% worse, 16% no change, and 82% better'; a distribution maintained between body sites and despite whether surgery was functional/symptomatic vs. cosmetic. Better outcomes were reported by patients who sustained traumatic scars vs. those who sustained scars by elective procedures (91.80% vs. 77.78%, P=0.016) and by females vs. males (85.52% vs. 75.36%, P<0.05), particularly in the elective group where males (36.17%) were more likely to report no change or worse outcomes versus females (16.04%) (P<0.01). CONCLUSIONS: Successful scar revision outcomes may be achieved using careful patient selection. This study provides useful information for referring general practitioners, and patient-surgeon consultations, when planning scar revision.

Botulinum Toxin Therapy versus Anterior Belly of Digastric Transfer in the Management of Marginal Mandibular Branch of the Facial Nerve Palsy: A Patient Satisfaction Survey.

BACKGROUND: Botulinum toxin (BT) chemodenervation and anterior belly of digastric muscle (ABD) transfer are both treatment options in the management of an isolated marginal mandibular branch of the facial nerve (MMB) palsy. We compare the patient satisfaction following either BT injections or ABD transfer in the management of their isolated MMB palsy. METHODS: Patients in the ABD-arm of the study were identified retrospectively from September 2007 to July 2014. The patients in the BT-arm of the study were identified prospectively from those attending the clinic. Both groups of patients completed a validated patient satisfaction survey. Statistical analysis was performed and a P-value <0.05 was considered statistically significant. RESULTS: Seven patients were in the ABD-arm and 11 patients in the BT-arm of the study. The patient satisfaction in both groups was high with 45% of ABD-arm patients and 40% of BT-arm patients rating their overall outcome as 'better' or 'much better', which was significantly more than the proportion rating their outcome as 'worse' or 'much worse' (P<0.001), although there was a significant trend towards those in the ABD-arm being more likely to be dissatisfied with their outcome (P=0.01). CONCLUSIONS: BT therapy is a good first-line intervention in the management of isolated MMB palsy. We have, however, shown that the overall satisfaction in both groups is high. Therefore, in patients who would prefer a more permanent solution to manage their facial asymmetry, ABD transfer remains a satisfactory treatment option with a good level of patient satisfaction.

An algorithm to guide recipient vessel selection in cases of free functional muscle transfer for facial reanimation.

BACKGROUND: The aim of this study was to review the recipient vessels used in our cases of facial reanimation with free functional muscle transfer and to identify patient variables that may predict when the facial vessels are absent. From this we present a protocol for vessel selection in cases when the facial artery and/or vein are absent. METHODS: Patients were identified from November 2006 to October 2013. Data was collected on patient demographics, facial palsy aetiology, history of previous facial surgery/trauma and flap/recipient vessels used. A standard operative approach was adopted and performed by a single surgeon. RESULTS: Eighty-seven eligible patients were identified for inclusion amongst which 98 hemifaces were operated upon. The facial artery and vein were the most commonly used recipient vessels (90% and 83% of patients, respectively). Commonly used alternative vessels were the transverse facial vein and superficial temporal artery. Those with congenital facial palsy were significantly more likely to lack a suitable facial vein (P=0.03) and those with a history of previous facial surgery or trauma were significantly more likely to have an absent facial artery and vein (P<0.05). CONCLUSIONS: Our algorithm can help to guide vessel selection cases of facial reanimation with free functional muscle transfer. Amongst patients with congenital facial palsy or in those with a previous history of facial surgery or trauma, the facial vessels are more likely to be absent and so the surgeon should then look towards the transverse facial vein and superficial temporal artery as alternative recipient structures.

The incidence of facial vessel agenesis in patients with syndromic congenital facial palsy.

BACKGROUND: Congenital facial palsy can result in significant disfigurement. A potential treatment option is free functional muscle transfer to reanimate the face. For this to be possible, a suitable recipient artery and vein must be present in the affected hemiface. In this study, the authors aim to identify whether patients with syndromic congenital facial palsy have a higher rate of facial vessel agenesis than those with isolated congenital facial palsy. METHODS: Patients were identified between November of 2006 and October of 2013. Patients were stratified into two groups: those with syndromic congenital facial palsy and those with isolated congenital facial palsy. The presence or absence of facial vessels was determined intraoperatively. RESULTS: Forty-seven eligible patients were included in the study. Those with syndromic congenital facial palsy were significantly more likely to have an absent facial vein than patients with isolated congenital facial palsy (p = 0.015). There was a strong trend toward those with syndromic facial palsy lacking a facial artery (p = 0.08). Subgroup analysis of patients with Möbius syndrome revealed that these patients were significantly more likely to have facial artery agenesis than those with isolated congenital facial palsy (p = 0.03). CONCLUSIONS: Facial vessel agenesis is significantly more common in patients with syndromic congenital facial palsy compared with those with isolated congenital facial palsy. This must be considered in the preoperative planning for facial reanimation with free functional muscle transfer. The operating surgeon should consider vascular studies of the affected hemiface before undertaking the procedure.

The perils of spinning class: an open ankle fracture following a spinning exercise session.

Spinning is an increasingly popular form of cycle-based exercise. The workouts are often of high-intensity and participants are intermittently encouraged to achieve a high crank-set-cadence rate. We report a unique case of an open ankle fracture requiring free flap coverage, which highlights the potential perils of spinning class.
