Assessment of Freestyle Local Facial Perforator Flaps for Coverage of Facial Defects.

OBJECTIVE: To assess local freestyle facial perforator flaps in the reconstruction of small to medium-sized facial defects. MATERIALS AND METHODS: In a case series, local freestyle perforator flaps were used in Suez Canal University Hospital to reconstruct 28 facial defects in 26 patients between 2017 and 2019. Adequate perforators were identified near those defects and flaps were designed as propeller or VY advancement. Four scales from the FACE-Q (satisfaction with facial appearance, satisfaction with the outcome, psychological function, and appearance-related psychosocial distress) and 2 scales from the SCAR-Q (Appearance scale and Symptom scale) were used as well as the observer part of the Patient and Observer Scar Assessment Scale. The mean follow up period was 10 months. RESULTS: Complete reconstruction was achieved in all cases with a high rate of patient satisfaction which was assessed by FACE-Q and SCAR-Q. Moreover, observer assessment by Patient and Observer Scar Assessment Scale score showed high patient satisfaction with the scars with a mean (SD) 15.5 (3.4) and there was a positive correlation between subjective and objective: results (r2 from 0.27 to 0.41, P < 0.01). Regarding complications, bulkiness occurred in 2 flaps, congestion in 2 flaps, dehiscence in 1 flap, and tip necrosis in 5 flaps. Accordingly, secondary intervention in the form of medicinal leech therapy was used in 3 flaps, delayed closure for the dehisced flap and debulking for 1 flap. CONCLUSIONS: Local freestyle perforator flap reconstruction is one of the recommended techniques for small to medium-sized facial defects which gives a high aesthetic outcome and patient satisfaction.

Aesthetic and functional outcomes of thinned anterolateral thigh flap in reconstruction of complex wounds of the upper limb.

We studied outcomes of reconstruction of complex upper limb wounds using thinned anterolateral thigh flaps. There were 18 patients with a mean age of 27.5 years. The mean thickness of the flap before and after thinning was 23 mm and 5 mm, respectively. Two patients had partial tip necrosis that was treated conservatively. Aesthetic and functional evaluations were performed using a 5-point Likert scale, QuickDASH score, passive range of motion and power grip at 12 months after surgery. The study showed good results in the aesthetic evaluation by a panel of plastic surgeons (mean score: 19.7) and patient self-assessment (mean score: 18.1). There was a significant correlation between the total scores of the panel and the patients. The mean QuickDASH score was 21, with a high percentage in the middle category 'had a problem but working'. The thinned anterolateral thigh flap is versatile and safe in upper limb reconstruction with good aesthetic and functional results.Level of evidence: IV.

Microbial cellulose dressing compared with silver sulphadiazine for the treatment of partial thickness burns: A prospective, randomised, clinical trial.

BACKGROUND: The current treatment for partial thickness burns at the trial site is silver sulphadiazine, as it minimises bacterial colonisation of wounds. Its deleterious effect on wound healing, together with the need for repeated, often painful, procedures, has brought about the search for a better treatment. Microbial cellulose has shown promising results that avoid these disadvantages. The aim of this study was therefore to compare microbial cellulose with silver sulphadiazine as a dressing for partial thickness burns. METHOD: All patients who presented with partial thickness (superficial and deep dermal) burns from October 2014 to October 2016 were screened for this randomised clinical trial. Twenty patients were included in each group: the cellulose group was treated with microbial cellulose sheets and the control group with silver sulphadiazine cream 10mg/g. The wound was evaluated every third day. Pain was assessed using the Face, Legs, Activity, Cry, Consolability (FLACC) scale during and after each procedure. Other variables recorded were age, sex, percentage total body surface area burned (TBSA%), clinical signs of infection, time for epithelialisation and hospital stay. Linear multivariable regression was used to analyse the significance of differences between the treatment groups by adjusting for the size and depth of the burn, and the patient's age. RESULTS: Median TBSA% was 9% (IQR 5.5-12.5). The median number of dressing changes was 1 (IQR 1-2) in the cellulose group, which was lower than that in the control group (median 9.5, IQR 6-16) (p<0.001). Multivariable regression analysis showed that the group treated with microbial cellulose spent 6.3 (95% CI 0.2-12.5) fewer days in hospital (p=0.04), had a mean score that was 3.4 (95% CI 2.5-4.3) points lower during wound care (p<0.001), and 2.2 (95% CI 1.6-2.7) afterwards (p<0.001). Epithelialisation was quicker, but not significantly so. CONCLUSION: These results suggest that the microbial cellulose dressing is a better first choice for treatment of partial thickness burns than silver sulphadiazine cream. Fewer dressings of the wound were done and, combined with the low pain scores, this is good for both the patients and the health care system. The differences in randomisation of the area of burns is, however, a concern that needs to be included in the interpretation of the results.

Autologous Bone Marrow Concentrates and Concentrated Growth Factors Accelerate Bone Regeneration After Enucleation of Mandibular Pathologic Lesions.

Stem cell therapy is a revolutionary new way to stimulate mesenchymal tissue regeneration. The platelets concentrate products started with platelet-rich plasma (PRP), followed by platelet-rich fibrin (PRF), whereas concentrated growth factors (CGF) are the latest generation of the platelets concentrate products which were found in 2011. The aim of the present study was to evaluate the potential of combining autologous bone marrow concentrates and CGF for treatment of bone defects resulting from enucleation of mandibular pathologic lesions. Twenty patients (13 males and 7 females) with mandibular benign unilateral lesions were included, and divided into 2 groups. Group I consisted of 10 patients who underwent enucleation of the lesions followed by grafting of the bony defects with autologous bone marrow concentrates and CGF. Group II consisted of 10 patients who underwent enucleation of the lesions without grafting (control). Radiographic examinations were done immediately postoperative, then at 1, 3, 6, and 12 months, to evaluate the reduction in size and changes in bone density at the bony defects. Results indicated a significant increase in bone density with respect to the baseline levels in both groups (P < 0.05). The increase in bone density was significantly higher in group I compared with group II at the 6- and 12-month follow-up examinations (P < 0.05). The percent of reduction in the defects' size was significantly higher in group I compared with group II after 12 months (P = 0.00001). In conclusion, the clinical application of autologous bone marrow concentrates with CGF is a cost effective and safe biotechnology, which accelerates bone regeneration and improves the density of regenerated bone.

Treatment of Children With Scalds by Xenografts: Report From a Swedish Burn Centre.

Scalds are the most common type of burn in children, and one way to treat them is with xenografts with no topical antimicrobials in line with the recommendations of a recent review. However, this treatment has not been examined in detail. Our aim was to describe the treatment of such children when biological dressings (xenografts) were used without local antimicrobials. We reviewed the medical records of all children admitted to a Swedish National Burn Centre during the period 2010-2012 with scalds who were treated with xenografts. Percentage TBSA injured, age, length of hospital stay, number of operations, antibiotics given, duration of antibiotic treatment, and pain score during the first 3 days, application of xenografts, and clinical notes of wound infection were recorded. We studied 67 children, (43 of whom were boys), with a median (interquartile range [IQR]) age of 1 (1-2) year and median (IQR) TBSA% 6.2 (4-11). Twenty children (30%) required operation. Twelve (18%) developed a wound infection, 29 (43%) had other infections, and 26 (39%) were free from infection. The median (IQR) duration of systemic antibiotics was 10 (6-13) days. On the day that the xenografts were applied 10 of the children had a Face, Legs, Activity, Cry, and Consolability (FLACC) score between 3 and 7, and during the following 2 days, only four children scored in this range. The remaining 57 children had scores < 3 on the day that xenografts were applied and on the following 2 days. Median (IQR) length of stay/TBSA% was 0.7 (0.4-1.0). Treatment with xenografts was associated with median length of stay/TBSA% <1 and low pain scores. Despite a high rate of prescription of systemic antibiotics, most were for reasons other than wound infection.

The functional intraoral Glasgow scale in floor of mouth carcinoma: longitudinal assessment of 62 consecutive patients.

The functional integrity of the floor of the mouth (FOM) is essential in maintaining tongue mobility, deglutition, and control and disposal of saliva. The present study focused on reporting oral function using functional intraoral Glasgow scale (FIGS) in patients who had surgical ablation and reconstruction of FOM carcinoma with or without chemo-radiotherapy. The study included patients who had surgical treatment of floor of mouth cancer in two regional head and neck units in Glasgow, UK between January 2006 and August 2007. Patients were assessed using FIGS before surgery, 2 months, 6 months and 1 year after surgery. It is a five-point scale self-questionnaire to allow patients to self-assess speech, chewing and swallowing. The maximum total score is 15 points. The influence of socio-demographic parameters, tumour characteristics and surgical parameters was addressed in the study. A total of 62 consecutive patients were included in the study; 41 (66.1 %) were males and 21 (33.9 %) were females. The patients' mean age at the time of diagnosis was 60.6 years. Fifty (80.6 %) patients had unilateral origin of FOM tumours and 10 (19.4 %) had bilateral origin. Peroral approach was the most common approach used in 35 (56.4 %) patients. The mean preoperative FIGS score was 14. Two months after surgery, it droped to 9.4 then started to increase gradually thereafter and recorded 10.1 at 6 months and 11 at 1 year. Unilateral FOM resection recorded better score than bilateral and lateral FOM tumours than anterior at 1 year postoperatively. Furthermore, direct closure showed better functional outcome than loco-regional and free flaps. The FIGS is a simple and comprehensive way of assessing a patient's functional impairment following surgery in the FOM. Tumour site and size, surgical access, surgical resection and method of reconstruction showed significant influence on oral function following surgical resection. A well-designed rehabilitation programme is required to improve oral function after surgical resection of oral cancer.
