Summary 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.

Functional outcomes were measured through visual acuity, slit-lamp examination of corneal and conjunctival staining, tear production (Schirmer’s 1 test), tear film break-up time, tear film meniscus height, quality and osmolarity, central corneal thickness and corneal sensation using Cochet–Bonnet esthesiometry. Structural outcomes were assessed from changes in corneal nerve density and morphology with IVCM. Subjective outcomes were assessed using VFQ-25 and latest telephonic consultation.Results: Between February 2016 and April 2018, 11 corneal neurotisations were performed on 11 patients (3 males, 8 females). Median age was 43 (range 25– 62) years. Mean follow-up was 14.5 (range, 4– 36) months. Snellen visual acuity improved in 6 patients, corneal and conjunctival staining decreased in 10, tear film breakup time increased in 9, tear meniscus height increased in 7, Schirmers test readings increased in 4, tear film osmolarity reduced in 8 and central corneal thickness increased in 10 patients. Corneal sensation improved in nine patients. Complete IVCM data were available in five cases and demonstrated an improvement of corneal nerve density and length at 12 months.Conclusion: This series confirms the fact that the outcomes of this technique are reproducible and that corneal neurotisation surgery helps restore trophic nerve function more consistently than touch-related sensation.Keywords: corneal neurotisation, neurotrophic keratopathy, sural nerve, corneal sensations

Scalp defects commonly occur as a result of tumour excision or trauma. The reconstruction of medium to large defects can be challenging due to the scalp laxity and hair growth pattern. We compare the outcome of patients who have had snail flap reconstruction in comparison to skin grafts. We conducted a retrospective case study of 45 consecutive patients’ over a 3-year period (2016–2018), across three sub-groups, viz. Fibonacci sequence flap, split skin graft and full-thickness skin grafts. The sub-cohorts were all matched for age, sex, indications and defect sizes before being analysed in terms of complication rates and wound healing rates over a 4-month period. The Fibonacci ‘snail’ flap was found to heal significantly faster than the full-thickness skin graft group and with lower complication rates overall, compared to skin grafts, but the latter outcome did not reach statistical significance. The aesthetic outcome of the Fibonacci flap though was superior to skin grafts both in terms of colour and contour match as well as hair restoration. The Fibonacci ‘snail’ flap is a sound option for the reconstruction of medium to large size defects of the scalp, even in those with poor performance scores, especially since its lower flap: defect ratio allows it to be performed under local anaesthesia. The advantage of the ‘snail’ flap over other scalp flaps will be determined in a future comparative study. Level of evidence: Level III, therapeutic study.

Summary:. Digital fingertip soft tissue defects requiring both reconstruction and revascularization pose challenges to the reconstructive surgeon. Traditional options, including terminalization, vein graft and cross-finger flap, and free flow-through flaps, maybe unsuitable or unavailable, with potential for significant donor site morbidity. Venous free flaps rely on venous circulation alone, with no sacrifice of an artery. We present a unique case of a self-employed tradesman with Raynaud’s disease, with four-finger injury, and three-finger ischemia for whom we performed a neurotized arterialized venous flow-through flap to revascularize and reconstruct a pulp defect (with a concomitant vessel gap of 2 cm). After allowing for a period of intrinsic delay, the neurotized arterialized venous flow-through flap was inset after 10 days. The flap survived and the patient began to return to his activities within a month of the injury.

Summary Introduction Lower motor neurone facial paralysis (LMNFP) is often viewed by the general public and wider non-facial palsy fraternity as a cosmetic issue rather than a functional one. In this article, we sought to determine the severity and frequency of oro-motor dysfunction in LMNFP and assess the benefits of physical therapy and rehabilitation in this cohort. Patients and methods A prospective study at our institute was conducted for a one-year period (2015–2016), involving adult patients with LMNFP with significant oro-motor dysfunction. The exclusion criteria were (i) pre-existing oro-motor dysfunction, (ii) within six months of facial palsy onset. The assessment tools used were (i) The Facial Disability Index (FDI), (ii) IPREDD or Inventory of Patient-Reported Eating and Drinking Dysfunction for mastication and (iii) a bespoked Visual Analogue Scale (VAS) based on focus group discussions. Results Of the 183 new clinic referrals, FDI identified that 14% of patients with LMNFP had significant oro-motor dysfunction. IPREDD analysis showed that 74% of this cohort had masticatory problems, while the VAS indicated significant oro-motor dysfunction as well in those with LMNFP. Following speech and facial therapy, IPREDD-focused symptoms were reduced from 74% to 43% (shown to be significant), while VAS similarly showed a significant reduction in symptoms (two-tailed, paired Student's t-test p Discussion Oro-motor function is a significant sequel of facial paralysis. Facial rehabilitation, both physical and psychological, can help reduce patients’ distress and improve oro-motor function, without the need for surgical intervention in the first instance.

Facial nerve palsy (FNP) often significantly affects blink. Platinum segment chains (PSC) improve lagophthalmos, however, debate exists as to the effectiveness of weights when the patient lies supine.Prospective case series of patients with FNP following PSC insertion. Lagophthalmos on blink, gentle and forced closure was observed in the seated position, lying flat supine at 0 degrees, lying supine with one pillow underneath the head and lying on the side, with the non-facial palsy side to the pillow. This side was chosen to account for the effect that the pillow may have on lagophthalmos.Twenty eyes with PSC for facial palsy related lagophthalmos were assessed in 19 patients. Clinically, 12 out of the 20 eyes had no change in lagophthalmos on gentle closure when sitting up compared to supine (no pillow). The remaining 8 eyes had an increase of lagophthalmos of mean 2.3 mm (range 1-6 mm) when supine. There was no statistical difference in the amount of lagophthalmos between sitting up and lying flat with no pillow on gentle closure (In our study, the prevalence of lagophthalmos increasing on gentle closure when supine is 40%. Statistically, there is no difference between gentle closure in the sitting and supine position.

Corneal neurotisation describes surgical restoration of nerve growth into the cornea to restore corneal sensation and trophic function. It represents an exciting and effective emerging treatment for neurotrophic keratopathy. Techniques described to date involve either direct nerve transfer or an interpositional nerve graft coapted to a healthy donor nerve. We review the experience to date with particular emphasis on a detailed review of techniques, outcomes and current thoughts.

Summary Introduction Clinical coding is often a mystery to us surgeons, but in actuality, it has a huge bearing on the financial sustainability of our services. Given the rapid innovations in plastic surgical procedures, clinical coders often struggle to decipher the extent of surgery. Meeting midway is the way forward here. Methods In a prospective audit over a six-month period, we analysed data from 2586 patients in our practice: a combination of general plastic surgery and specialist facial reanimation services. This involved comparing data from the first three months where coding was performed by clinical coders based on operating notes per se (phase I) and the subsequent three months when the operating surgeon filled in the OPCS 4.7 (version 2014) codes at the time of completing the operating notes; the clinical coders then vetted this information (phase II) as part of a sequential TBS coding system. Results In terms of outpatient income, there was a 3% increase in facial palsy income and 6% increase in general plastic services, but the most significant improvement was in terms of procedural income per case. General plastic surgery cases saw an increase of 49%, while facial palsy income increased by 58% over the same period. Greater insight into OPCS and HRG codes also allowed for the calculation of the actual tariffs for specific procedures. Conclusions Having the operating surgeon as the primary coder, using a template, with subsequent vetting by the clinical coders, improves data capture, and this in turn increases income. Future recommendations include the use of proforma-based operating notes for workhorse procedures.

AimTo report the functional and aesthetic outcomes of eyelid full-thickness skin grafting (FTSG) in patients with facial nerve palsy (FNP).MethodsThis is a retrospective, non-comparative, single-centre review of all patients with FNP who underwent FTSG over an 8-year period. Functional outcomes were collected through case notes review: CADS (cornea, static asymmetry and dynamic and synkinesis) score facial nerve grading and lagophthalmos on blink, gentle and forced closure. Marginal reflex distance (MRD1 and MRD2) was calculated on standardised photographs. The aesthetic outcomes were assessed objectively by two blinded independent assessors who assessed standardised photographs based on a mutually agreed grading scale. Both functional and aesthetic outcomes were measured preoperatively, and at early (1–3 months), intermediate (3–6 months) and late (>9 months) postoperative periods.ResultsA total of 28 eyelid FTSGs were performed on 21 patients (11 female, 10 male) between 2008 and 2016. The mean age was 68 (range, 16–89) years and the mean follow-up was 20.8 (range, 12–30) months. The CADS score (cornea (pConclusionThe use of periocular FTSG is effective in improving lagophthalmos and periorbital symmetry in patients with FNP where skin contraction exists. They should be considered as an adjunct to other oculoplastic procedures for both functional and aesthetic rehabilitation.

The evolution of the angiosome concept into the perforasome theory as we increasingly move towards the distal end of the microvascular tree for reconstructive options has allowed us to design ad hoc perforator flaps. In a retrospective sample of more than 60 pedicled perforator flaps over a 36-month period, a variety of defects in all regions of the body were reconstructed. Pre-operative planning was based on either Doppler vascular studies or CT angiography. The overall complete flap survival rate was 89%, with a tip necrosis rate of 8.1% and a partial flap necrosis rate of 3.3%. The risk factors identified were smoking, nicotine patches, vasopressor use and pro-thrombotic states. It is feasible to perform the many variations of perforator flaps provided; the microsurgical anatomy of the area is well defined, aided by imaging studies as necessary. Risk stratification also needs to be taken into account when planning these flaps. Based on our results and observations, an alternative pedicled perforator flap classification is put forward. Level of Evidence: Level IV, therapeutic study.

Injuries to the parotid ducts are difficult to locate, assess, and repair, and traditionally, solid metal dilators and soft plastic tubes have had only limited success. We describe the Seldinger technique with a central venous catheter, which makes repair easier.

Summary Objectives To assess for functional improvement in outcomes following supermicrosurgical restoration across a cohort of patients with a spectrum of trigeminal nerve disorders. Patients & methods In a retrospective case series over three years (2016–18), twenty patients were included in a cohort of trigeminal nerve palsy patients. Eleven patients with corneal anaesthesia underwent corneal neurotisation procedures and were followed up using Cochet-Bonnet aesthesiometry. Six patients with sensory trigeminal nerve injuries had direct nerve coaptation and neuroma excision. Three patients with trigeminal motor nerve palsies were followed up with photography for contour improvement. Results Regarding corneal neurotisation, there was evidence of significant improvement in protective corneal sensation and also blinking frequency. Regarding facial sensory disturbances, all patients had full resolution of painful trigeminal neuroma symptoms. In two cases of iatrogenic trigeminal motor palsies with contour defects, adipo-fascial variants of the superficial circumflex iliac artery (SCIP) free flap achieved excellent restoration of facial contour in lieu of facial lipofilling. In another case of a necrotising infection of the head and neck with loss of all masticatory muscles, a free functional muscle using a chimaeric vastus lateralis-ALT flap was used to restore masticatory and facial movement in a single stage procedure. Conclusion Using combinations and permutations of current surgical techniques, it is possible to successfully restore both form and function for patients with sensory as well as motor trigeminal nerve palsies. This sets a precedent for the expansion of cranial nerve surgery as an evolving sub-speciality.

The scalp rotation flap is still the flap of choice for scalp defects as it provides hair-bearing skin, replacing “like with like,” and can be designed to respect hairlines and patterns.1 Conventionally, these flaps are planned to be up to 8 times the diameter of the defect to allow for sufficient recruitment of scalp laxity and allow for primary closure of the secondary defect. Nevertheless, its use is limited by large flap to defect ratios (See Video [online], which displays the surgical technique of the “snail flap”). Video 1. This video displays the snail flap technique demonstrated in the article. From “The "Snail Flap": A Rotation Flap in Scalp Reconstruction” Following the creation of the scalp defect, the thickness of the scalp is measured. If it is less than 5 mm, a snail flap is raised, as shown in the video, with a “flap:defect” ratio of 2:1. The tip of the flap is folded onto itself and advanced into the primary defect first. The secondary defect is then closed by spreading the tension across the entire arc. In younger patients, where the scalp thickness tends to be greater than 5 mm and there is increased scalp laxity, a “flap:defect” ratio of 1.5:1 may be chosen as the greater scalp laxity accords ease of closure (Fig. 1).

This case series compares clinical vs magnetic resonance imaging/electromyography assessment of masseter width after masseteric nerve harvest with the Borschel method.

Prof. Koushima, president of World Society for Reconstructive Microsurgery, proposes an innovative concept and technique of the multi-stage ‘Orochi’ combined flaps (sequential flaps in parallel). The technique opens a new vista in reconstructive microsurgery.

The best outcomes after injury to the facial nerve are seen after immediate direct coaptation, but in practice, this happens infrequently. We ask whether late repair (between 3 weeks and 18 months) is comparable to immediate repair. In this prospective observational study over a two-year period (2016–18), we identified 18 patients (11 male and 7 female, mean (range) age 58 (23–94) years), who had sustained extracranial injuries to the facial nerve. Eight were identified in the acute phase (within 72 hours of injury) and repaired (immediate repair group). Ten presented in the late phase beyond six months (late repair group), and had direct coaptation, neurolysis, nerve transfer, or non-vascularised or vascularised nerve grafts. Patients were followed up clinically with photographic or video analysis every three months using the Sunnybrook facial grading scale and Terzis scores as quantitative tools. In the immediate repair group six patients had direct nerve coaptations, one had a free vascularised nerve graft, and one a fascicular nerve flap. In the late repair group six patients had coaptations, two had nerve transfers, one had neurolysis, and one nerve transfer and a free vascularised nerve graft. The null hypothesis that there was no difference between immediate and late repair of the facial nerve in terms of clinical improvement was accepted. The overall facial grading scale between the two groups showed no significant difference (mean 97 compared with 87; 95% CI: −25.61 to 5.32; p = 0.18). However, the individual volitional facial grading score for the affected division showed that immediate repair fared significantly better than late repair (mean 4.55 compared with 3.14; 95% CI: −2.5 to −0.3; p = 0.027). Supermicrosurgical techniques, together with advanced systems for nerve identification allow for coaptation of the maximum number of injured nerve branches. These factors accounted for a 97% mean return of function after immediate repair and an 87% recovery in the late repair group. While quantitatively, immediate repair is best, the re-establishment of nerve-muscle continuity before degeneration of the motor endplate confers the best possible physiological outcome, and is far superior to any of the techniques used to treat chronic facial paralysis.

Charles Redmond McLaughlin was a pioneer in both facial palsy surgery and in facial plastic surgery (East Grinstead, 1946-1969). Thanks to his work, the personalised treatment of facial palsy was begun.

This case report demonstrates an important supermicrosurgical technique for lymphedema, which was established by Isao Koshima in 1994. So far, over 2,000 cases of limb edema have been treated by this surgical method.

This study aimed to provide reliable and valid evidence that botulinum toxin type A (BTX-A) is a successful treatment for facial synkinesis in facial palsy by using the synkinesis assessment questionnaire (SAQ) tool. Fifty-one patients completed questionnaires pre- and post-BTX-A treatment over 103 cycles of treatment. Each patient was individually assessed and then treated according to their presenting symptoms with a dosage in each injection site of between 0.5 and 5 U of BTX-A. A two-tailed paired samples t-test was used to compare the scores for each question before and after treatment. A significant difference was found between all scores before and after treatment at the level of p 0.05. There was not only an improvement in the mean score in the post-treatment group but also a smaller spread of scores in the post-treatment group than in the pre-treatment group. The study showed that SAQ scores decreased significantly for every question on the SAQ after treatment. This indicates that BTX-A is an effective treatment for synkinesis, adding further weight to current evidence. The study also indicated that BTX-A continues to be effective even after three rounds of treatment, with a significant decrease in overall scores after each treatment cycle.

The centre ground in the world of flaps have over time, gradually shifted from tubed pedicled, random-pattern, axial-pattern, pedicled, free and currently, to free-styled flaps. These concepts are broadly based on the angiosome-perforasome concept. In this case report, we illustrate how the concept of venosome capture can be transposed onto reverse-flow flaps with the aid of venous supercharging. Moreover, if this is seen from the free-styled flap perspective, it requires supermicrosurgical expertise. This case report hence, serves as a fusion of all the above concepts.

Facial nerve disorders present with varying levels of facial dysfunction. Facial nerve reinnervation techniques aim to correct this by attempting to reestablish the connection lost between the facial nerve nucleus and its distal branches, or by using donor nerves to provide an alternate neural input to the facial nerve. Many facial nerve disorders exist; however, tumors and trauma to the facial nerve are the 2 causes that most commonly result in the patient being considered for reanimation procedures, as they most often result in facial nerve discontinuity. Reinnervation techniques are the first line surgical intervention for facial paralysis when a direct connection between the facial nerve cannot be reestablished, with the XII-VII nerve transfer being the most reliable and having the most predictable outcome when compared with the alternative VII-VII procedure. However, when the reinnervation time window is missed, other techniques of reanimation must be used in an attempt to best restore the normal symmetry and function of the face. The modifications to the XII-VII nerve transfer technique have made it the most popular of all methods; however, there are still many other nerves that may be considered as donors, giving the surgeon other options in the event of the hypoglossal (XIIth) nerve being unsuitable.

In this case, reported in line with the SCARE criteria, we describe an acute facial palsy, presenting in a similar manner to Bell’s palsy, albeit with minor differences. Although clinical suspicion for malignancy was raised and gold standard serological and radiologic tests were requested, no abnormalities were found preoperatively. However, as a prelude to a planned babysitter procedure, as the facial nerve was explored, multiple masses were found in both the superficial and deep lobes of the parotid gland. This was later proven to be a malignant melanoma tumor. On review of literature, it is evident that although rare, about 1% of parotid cancers can present with facial paralysis as the sole symptom. Rarer still, is the underlying etiology; primary parotid melanoma in this case, which carries a very poor prognosis. On the basis of this, we propose extra vigilance when dealing with such cases and suggest a clinical protocol for use to aid diagnosis and subsequent surgical management.
