Peri-implant keratinized mucosa (PI-KM) may support implant survival. Acellular collagen matrices (aCMs) have been widely used to facilitate soft tissue regeneration. The aim of this study was to investigate clinical outcomes obtained with the use of an aCM (mucoderm®) to enhance PI-KM. In this retrospective non-randomized case series, 27 restored implants in 14 patients (eight males and six females, mean age = 56 years) with a PI-KM width ≤ 1 mm were followed for 6 months. It was demonstrated that aCM grafts augmented PI-KM effectively (mean increase of 5.4 mm; >533%) without a significant change in bleeding on probing (BOP) from baseline. The mean aCM shrinkage was 3.9 mm (42%). Gender, area, arch, and BOP did not influence PI-KM augmentation or aCM shrinkage significantly. The present results demonstrated that the examined aCM was effective and predictable for attaining a band of keratinized tissue, while avoiding graft donor site harversting.

Abstract Background The revolving door flap, although well described in the literature, is not widely used in general plastic surgery practice. The flap has been used for anterior auricular and conchal defects and is considered elegant for its unique flap design and peculiarity of flap harvest. However, due to its use for a very specific purpose and unique flap harvest technique that may be difficult to grasp, the flap is not very popular in reconstructive practice. Objectives This study aims to evaluate the understanding and learning curve of the revolving door flap, assess surgical outcome, and reemphasize its utility and elegance in reconstruction of ear defects. Methodology This is a case series of nine surgeries performed between January 2014 and 2018. Three cases were performed by the senior author and six cases by two junior authors. Patients were observed for complications and aesthetic outcomes. Results The mean dimension of the flaps was 27.22 mm × 22.78 mm. The mean operative time was 56.56 minutes (standard deviation 22.50, standard error of the mean 7.5). Flap congestion was noted in three cases postoperatively which resolved completely by the second week. Major “pinning” of the ear was noted in four cases. Conclusion Though infrequently performed, the revolving door flap has an easy learning curve once the proper harvest technique and flap movement has been grasped. The flap harvest is convenient, safe, and yields predictable results. Not only is total or partial flap loss extremely rare, the flap is sensate, color match is good, auricular contour is maintained, and the donor site can be closed primarily and remains well hidden.

Objective Analyze the reliability, complications, and donor site morbidity of the proximal lateral leg flap when applied to head and neck reconstruction. Study Design Case series and chart review. Setting Tertiary care teaching hospital. Subjects and Methods Nineteen patients who underwent reconstruction of various head and neck defects with this flap were analyzed. The patient demographics, flap characteristics, method of donor site closure, scars of the donor area, complication rates, as well as functional results at the recipient site were assessed. Results The flap size ranged from 4 × 4 cm to 11 × 8 cm. Vascular pedicle length ranged from 5 to 9 cm. The mean distance of the perforator from the fibula head was 9.2 cm. The mean thickness of this flap was 5.5 mm. All the donor wounds were closed primarily. The flap survival rate was 100%. Conclusion This flap has the advantages of thinness, short harvesting time, minimal donor site morbidity, and primary closure at the donor site when the flap width is less than 6 cm. This flap may be useful for reconstruction in selected patients with small and thin heads and neck defects.

A anatomia do tecido mole peri-implantar é semelhante à do dente natural, uma vez que apresenta epitélio juncional e tecido conjuntivo. O selamento peri-implantar é estabelecido pela mucosa ceratinizada que previne a migração apical da margem gengival, mantendo a arquitetura tecidual e estética vermelha ao redor dos implantes osseointegráveis. O presente trabalho objetivou relatar um caso clínico de reconstrução de tecido mole previamente a cirurgia óssea reconstrutiva para a instalação de implante osseointegrável. Após a reconstrução do tecido mole observou-se que houve um satisfatório ganho de altura e espessura tecidual. Foi obtido um volume tecidual suficiente para regularização do zênite gengival e considerável volume de mucosa ceratinizada foi obtida previamente a cirurgia reconstrutiva.Descritores: Implantes Dentários; Periodontia; Reabilitação Bucal.ReferênciasMutthineni RB, Dudala RB, Ramisetty A.

Bone marrow aspirate concentrate (BMAC) is an autologous cell composition that is obtained through a needle aspiration from the iliac crest. The purpose of this study was to evaluate the outcomes of patients treated with open reduction and internal fixation with BMAC supplementation for clavicle fracture nonunion. This was a retrospective case series of 21 consecutive patients with clavicle fracture nonunion that were treated with ORIF and BMAC supplementation between 2013 and 2020. Patients were evaluated for fracture union, time to union, complications related to surgical and donor site, and functional outcome using the Quick Disability of the Arm Shoulder and Hand (QDASH), subjective shoulder value (SSV), and pain. The mean age was 41.8 years. The mean follow-up was 36 months. Twenty (95.2%) patients demonstrated fracture union, with a mean time to union of 4.5 months. Good functional scores were achieved: SSV, 74.3; QDASH, 23.3; pain level, 3.1. There were no complications or pain related to the iliac crest donor site. Supplementary BMAC to ORIF in the treatment of clavicle fracture nonunion is a safe method, resulting in high rates of fracture union and good functional outcomes with minimal complications and pain.

Background: Painful dysfunctional shoulders with irreparable rotator cuff tears (IRCTs) in active patients are a challenge. Arthroscopic superior capsular reconstruction (ASCR) is a new treatment option originally described using a fascia lata autograft harvested through an open approach. However, concerns about donor site morbidity have discouraged surgeons from using this type of graft. Hypothesis: ASCR using a minimally invasive harvested fascia lata autograft produces good 6-month and 2-year shoulder outcomes in IRCTs, with low-impact thigh morbidity at 2 years. Study Design: Case series; Level of evidence, 4. Methods: From 2015 to 2016, a total of 22 consecutive patients (mean age, 64.8 ± 8.6 years) with chronic IRCTs (Hamada grade 1-2; Goutallier cumulative grade ≥3; Patte stage 1: 2 patients; Patte stage 2: 6 patients; Patte stage 3: 14 patients) underwent ASCR using a minimally invasive harvested fascia lata autograft. All patients completed preoperative and 6-month evaluations consisting of the Simple Shoulder Test (SST), subjective shoulder value (SSV), Constant score (CS), range of motion (ROM), acromiohumeral interval (AHI), and magnetic resonance imaging. Twenty-one patients completed the 2-year shoulder and donor site morbidity assessments. Results: The mean active ROMs improved significantly ( P < .001): elevation, from 74.8° ± 55.5° to 104.5° ± 41.9° (6 months) and 143.8° ± 31.7° (2 years); abduction, from 53.2° ± 43.3° to 86.6° ± 32.9° (6 months) and 120.7° ± 37.7° (2 years); external rotation, from 13.2° ± 18.4° to 27.0° ± 16.1° (6 months) and 35.6° ± 17.3° (2 years); and internal rotation, from 1.2 ± 1.5 points to 2.6 ± 1.5 points (6 months) and 3.8 ± 1.2 points (2 years). The mean functional shoulder scores improved significantly ( P < .001): SST, from 2.1 ± 2.9 to 6.8 ± 3.5 (6 months) and 8.6 ± 3.5 (2 years); SSV, from 33.0% ± 17.4% to 55.7% ± 25.6% (6 months) and 70.0% ± 23.0% (2 years); CS, from 17.5 ± 13.4 to 42.5 ± 14.9 (6 months) and 64.9 ± 18.0 (2 years). The mean shoulder abduction strength improved significantly ( P < .001) from 0.0 to 1.1 ± 1.4 kg (6 months) and 2.8 ± 2.6 kg (2 years). The mean AHI improved from 6.4 ± 3.3 mm to 8.0 ± 2.5 mm (6 months) and decreased to 7.1 ± 2.5 mm (2 years). This 0.7 ± 1.5–mm overall decrease was statistically significant ( P = .042). At 6 months, 20 of 22 patients (90.9%) had no graft tears. At 2 years, 12 of 21 patients (57.1%) were bothered by their harvested thigh, 16 (76.2%) noticed donor site changes, 16 (76.2%) considered that the shoulder surgery’s end result compensated for the thigh’s changes, and 18 (85.7%) would undergo the same surgery again. Conclusion: ASCR using a minimally invasive harvested fascia lata autograft produced good 6-month and 2-year shoulder outcomes in IRCTs, with low-impact thigh morbidity at 2 years.

This article aims to demonstrate an individualized approach to an elderly patient requiring scalp reconstruction, to describe the methodology in flap selection, lessons learned, and report outcomes. A retrospective review of a single surgeon's experience of scalp reconstruction (E. D. R.) using free tissue transfer from 2005 to 2011, in patients older than 70 years, was completed. A total of eight patients met the inclusion criteria, five males and three females, with a mean age of 80.4 years (range, 73–92). Free tissue transfer achieved 100% soft tissue coverage. Six of the eight patients required cranioplasty. The mean size calvarial defect was 92 cm2 (range, 35–285 cm2). The mean flap size was 117.6 cm2 (range, 42–285 cm2). Free flaps included three ulnar, three anterolateral thigh, one latissimus dorsi, and one thoracodorsal perforator flap. The mean follow-up time was 18.4 months (range, 3–46 months). Donor site morbidity was minimal. Mortality was 0%. Immediate flap failure was 0%. Other complications occurred in six of the eight patients. Mean revisionary procedures were 1.25 procedures per patient. It was concluded that chronological age does not increase mortality or catastrophic flap complications; however, morbidity is increased in the elderly and revisionary surgery is likely.

OBJECTIVES: The study goal was to show that the lateral arm flap is a viable reconstructive option for complex parotidectomy defects. STUDY DESIGN AND SETTING: We studied a case series at a tertiary care medical center from March 1997 to March 2002. The lateral arm flap was used to reconstruct parotidectomy defects that included a composite resection of adjacent tissue in 30 patients. There were 19 men and 11 women (mean age, 62 years; mean follow-up, 19 months). The mean flap area was 114 cm2, and the mean flap volume was 172 cm3. The posterior cutaneous nerve of the forearm (PCNF) was used as a facial nerve cable graft in 14 patients. Facial disability outcomes were measured using the Facial Clinimetric Evaluation scale. RESULTS: The major and minor complication rates with use of this reconstructive approach were low: 16.7% (5 of 30) and 26.7% (8 of 30), respectively. Donor site morbidity was minimal, with no patient having a major donor site complication and 23.3% (7 of 30) having minor complications. Functional recovery of the facial nerve occurred in 6 of 8 evaluable patients who underwent facial nerve grafting using the PCNF. Controlling for degree of facial nerve paralysis, Facial Clinimetric Evaluation scale scores of our patients were not statistically different than those of a historic population with a facial paralysis and no surgical defect. CONCLUSIONS: The lateral arm free flap effectively restores facial appearance when used for reconstruction of complex parotidectomy defects. The PCNF, a nerve harvested with the lateral arm flap, can be used as a facial nerve cable graft with a high rate of success. SIGNIFICANCE: The lateral arm flap is successful as a single donor site for reconstructing facial contour and the facial nerve after major ablative defects in the parotid region.

Introduction: Multiple gingival recessions (GR) are often associated with high hypersensitivity and esthetics concerns due to exposed roots. The collagen matrix (CM) associated with coronally advanced flap (CAF) may be a suitable treatment for multiple GR in esthetic areas. However, there is a lack of long term follow up investigations. Objective: To evaluate a 24-month follow-up of the CM + CAF treatment for multiple RT1 GRs in esthetics areas. Materials and Methods: Six patients presenting 6 adjacent Cairo’s gingival recessions type 1 (RT1) in the anterior maxilla were treated with CM + CAF, and based on these patients a brief statistical analysis was conduct. The evaluated parameters included gingival recession depth (GRD), gingival recession width (GRW), probing depth (PD), clinical attachment level (CAL), keratinized tissue width (KTW), gingival thickness (GT), and mean root coverage (MRC). Patient-related outcomes measurements (PROMs) were assessed using an oral health impact profile (OHIP-14) questionnaire and visual analogue scale (VAS).  Results: There was significant improvement in GRD, GRW, and CAL measurements at 3 months postoperatively (p<0.05). Besides, CAL also increased from 12 months to 24 months’ follow-up (p=0.0023). The MRC percentage was 82%. PD, GT, and KTW presented no statistical difference. PROMs revealed a high score for esthetics (82.2%) and a significant reduction in hypersensitivity and surgical pain/discomfort. Conclusions: Considering the limitations of a case series, the use of CM + CAF on RT1 multiple gingival recessions in esthetic areas demonstrated positive outcomes after 24 months.

Abstract Purpose: With the development of microsurgical techniques, the anterolateral thigh (ALT) flap has been widely used in reconstruction of various soft-tissue defects. However, there were few studies focusing on the closure of the ALT flap donor site, especially when the width of the harvested ALT flap was more than 6 cm. The purpose of this study was to share our experience of using Keystone Design Perforator Island Flap (KDPIF) to repair the ALT flap donor site where can’t be closed without a skin graft.Method: A retrospective study was used to analyze 12 patients who underwent the reconstruction of the ALT flap donor site using KDPIF from February 2018 to December 2020. Demographics, flap characteristics, surgical technique, postoperative complications, Vancouver Scar Scale (VSS) score, and Scar Cosmesis Assessment and Rating (SCAR) score were statistically analyzed.Results: 12 patients (10 males, 2 females) with the mean age 47.5 years (range, 27-66 years) were included in this study. All ALT flap donor sites were closed by the KDPIF. The mean size of the harvested ALT flap (the donor site size) was 8.1 cm × 14.4 cm (range from 8.0 cm × 11.0 cm to 9.0 cm × 21.0 cm), and the mean size of keystone flap was 9.1 cm × 16.4 cm (range from 8.0 cm × 13.0 cm to 12.0 cm × 19.0 cm). At the mean follow-up of 8.3 months (range, 6-12 months), two patients suffered from the skin infection around the flap, which was controlled under the treatment of wound dressing change and oral antibiotics. Wound dehiscence, osteofascial compartment syndrome (OCS), venous return disorder, and skin necrosis were not presented in any patients. All patients were evaluated at the final follow-up with ASS core (mean, 6.7; range, 5-8) and SCAR core (mean, 7.3; range, 6-9).Conclusion: This study demonstrated that the KDPIF that can be used to close the ALT flap donor site primarily is an effective and alternative treatment for patients with a the width of the donor site more than 6 cm including the advantages of high survival rate, low morbidity, good aesthetics, and simple operation.

Background: Split thickness skin graft (STSG) is one of the modalities used to close a defect. The donor site can be healed secondarily with tulle grass and moist gauze after 14 days and with transparent dressing will take about 10-13 days. Recently the wound healing by using honey application has been used. Whether or not using honey application with transparent dressing will hasten the epithelialization rate of the STSG donor site is now in question. Method: This research is an open, non-randomized clinical trial with a parallel design and intervention using honey application with transparent dressing. A total of 19 patients (7 female and 8 male) were included in this study. The reapplication of honey was done every two days. The patients was followed up every day, with clinical photograph taken and complaints such as pain, odor and infection noted. Results: The mean epithelialization rate of the donor site treated with honey and transparent dressing was 9,74 (+0,24) days compared to 10,79 (+1,23) days in the transparent-dressing-only group (p=0,00). Conclusion: The application of honey with transparent dressing to cover for STSG donor site led to a faster epithelialization rate, less odor and less pain. Commercial honey was used, and readily available.
