Unique Characteristics and Applications of Reverse Superior Labial Artery Island Flaps: A Case Series.

Background: The reverse superior labial artery (rSLA) island flap can be used to reconstruct the cheek, ala, columella and vestibule of the nose when other techniques appear insufficient or impractical. The aim of this case series was to present applications of rSLA pedicle flaps in the post-ablative oncologic reconstruction of the face. Patients and Methods: Using a retrospective case-series study design, the investigators enrolled a cohort of patients undergoing procedures involving rSLA flaps treated at a Polish Otolaryngology Department for facial reconstruction after tumour excision. The main outcomes were functional and aesthetic aspects. Descriptive statistics were computed as appropriate. Results and Conclusions: The use of rSLA flaps allows surgeons to obtain a large skin island with only minimal cosmetic and functional alterations. In all of the cases in this series, the use of this pedicle flap resulted in both optimal healing and satisfactory cosmetic and functional outcomes.

Comparison of reverse dorsoradial flap for thumb reconstruction: narrow pedicle versus wide pedicle.

INTRODUCTION: The reverse homodigital dorsoradial flap remains a useful alternative for covering thumb defects. However, the description of pedicle width of dorsoradial flap is not clear. The aim of this study was to compare the results of narrow pedicle with wide pedicle in dorsoradial flaps and describe our experience with the thumb reconstruction. MATERIALS AND METHODS: From July 2014 to February 2019, 42 patients were treated with the reverse dorsoradial flap for thumb reconstruction. The patients were divided as Group A (pedicle width ≤ 0.8 cm) and Group B (pedicle width > 0.8 cm). Flap survival, time to return to work, flap sensibility, the range of motion (ROM) of the joints, and final aesthetic outcomes were evaluated. RESULTS: Respectively in the Group A (17 cases) and Group B (25 cases), 14-19 flaps survived uneventfully, whereas 3-6 flaps experienced venous congestion with no or partial flap loss. No significant difference was identified between the two groups for the incidence of venous congestion, static 2-point discrimination and ROM of the injured thumbs. Time to return to work was significantly shorter in Group A. The aesthetic satisfaction of the patients in Group A was significantly better comparing with that in Group B. CONCLUSIONS: The reverse homodigital dorsoradial flap with narrow pedicle width is associated with more favorable outcomes in terms of time lost from work and aesthetic satisfaction of the patients.

Distally Based Saphenous Neurocutaneous Perforator Flap: A Versatile Donor Site for Reconstruction of Soft Tissue Defects of the Medial Malleolar Region.

Repair of both simple and complex defects in the medial malleolar region continues to be a challenging task for surgeons because of the local paucity of soft tissue available for transfer. The popular neurocutaneous flap has provided a reliable and less technically demanding method for resurfacing defects of the lower extremities. We present our experience with the versatile design of the distally based saphenous neurocutaneous perforator flap to provide coverage of complex post-traumatic medial malleolar defects by harvesting multiple tissue components in various combinations. Our series included 11 patients (8 males [72.7%] and 3 females [27.3%]); mean age 39.2 (range 22 to 58) years, who were followed for a mean duration of 13.3 (range 9 to 18) months. Three flaps (27.3%) were harvested with massive subcutaneous tissue to obliterate dead space. The procedure was uneventful in 10 patients (90.9%). Venous congestion was noted in 1 patient (9.1%), in whom secondary healing was achieved with conservative treatment.

Clinical application of an expanded reverse-island flap with two dorsal metacarpal arteries and dorsal metacarpal nerves in index- and middle-finger-degloving injury repair and amputation reconstruction.

The dorsal metacarpal artery flap (DMAF) is irrefutable as an effective way of repairing long finger defects, and hand surgeons might consider using it for long finger reconstruction or degloved injury repair. Unfortunately, the DMAF containing a single dorsal metacarpal artery (DMA) hinders the treatment effect. The sensory restoration of long fingers and the reconstruction of phalangeal joints and tendon grafts are unsolved challenges as well. We reported our experience in reconstructing the index and middle finger by a reverse-island flap with two DMAs and dorsal metacarpal nerves (DMNs) with blood supply. We reviewed ten patients with finger-crush injuries affecting eight index fingers and two middle fingers. Degloving injuries occurred in two patients, and finger amputations occurred in eight others. Two patients received simple flap reconstruction, and eight received finger reconstruction, including seven from abandoned phalangeal joints and tendon grafts of the severed finger and one from the iliac crest bone graft. All patients underwent finger reconstruction by an expanded reverse-island flap consisting of two DMAs and DMNs up to a maximal size of 9 × 8 cm2. Postoperative follow-up evaluation showed a satisfactory appearance and functional recovery of the reconstructed fingers. We posit that the expanded reverse-island flap involving two DMAs and DMNs constitutes a feasible and safe option for restoring a severely damaged index or middle finger, particularly for patients who are unwilling to undergo toe-to-finger transplantation to reconstruct the injured long fingers.

ALTERING THE MARKING OF THE REVERSE POSTERIOR INTEROSSEOUS ARTERY FLAP.

Background: Full-thickness defects on the dorsum of the hand requires thin, soft, and pliable skin for which there are limited locoregional flaps. The reverse posterior interosseous artery (PIA) flap based on the communicating artery fulfills all above requirements and can reach upto the fingers. However, there has been discrepancy in the surface marking of the flap and the anatomical position of the vessel pedicle. We share our alteration with the marking and ease of harvesting this flap. Method and material: This is a prospective study conducted at a private teaching hospital in Karachi, over a period of 2 years from November 2017 to December 2019. After taking consent and ensuring confidentiality of all patients who had PIA flap reconstruction, we collected patient's demographic details, mode of injury, and flap surface area. We altered the described skin marking and took measures to prevent venous congestion and noted the outcomes in term of flap congestion and flap loss. Results: Twenty-eight patients with a mode age of 32 years were operated during this period. The majority (64.2%) had a motor vehicle accident and machine injuries. The mean surface area of flaps was 6 × 10 cm2, and 11 (39.2%) flaps had venous supercharging. All patients had a 10-20° wrist extension splint for 2 weeks. The mean follow-up of the patients was 14 ± 5 days, and 6 (21.4%) flaps developed a minimal marginal flap loss, which was managed conservatively. Conclusion: By minimally altering our surface marking, we experienced a easy and quick harvesting of this flap. However, one has to be vigilant and take all described precautions for venous congestion.

The post-traumatic reconstruction of nail bed defects using a homodigital dorsal adipofascial reverse flap.

Nail bed defects (NBDs) of the distal phalanx, are common and remain challenging to reconstruct. This study aimed to evaluate the clinical outcome of these post-traumatic injuries treated using a homodigital dorsal adipofascial reverse flap (HDARF). Sixteen patients, averaging 43-years-old, were retrospectively reviewed, who underwent the aforementioned procedure from February 2018 to December 2019. Range of motion of the distal interphalangeal (DIP) joint, static Weber's 2-point discrimination sensibility of the pulp, the percentage of nail adherence, complications, patient's satisfaction, subsequent nail regrowth, and flap survival were evaluated upon follow-up. At 26 months average follow-up, the percentage of flap survival was 100%. Complete regrowth of the nail was reported in 11 cases (69%), on average 4.7 months after surgery. A total absence of ungual regrowth was noted in 5 cases (31%). The mean static Weber's 2-point discrimination value of injured finger was 4.25 mm, reconstructed fingers' mean range of motion for the DIP joint was 75 degrees. Patient satisfaction was graded as very satisfying in 11 cases (69%), satisfying in 4 cases (25%), and disappointing in 1 case (6%). The HDARF is a good alternative for the management of NBDs of fingers and thumb. It yielded functionally and aesthetically acceptable results with low donor site morbidity. LEVEL OF EVIDENCE: IV.

A randomized trial of use of a modified reverse sural neurofasciocutaneous flap to extend the reconstruction range.

BACKGROUND: When a reverse sural neurofasciocutaneous flap is used to reconstruct a forefoot defect, usually, the transverse length of the flap is increased or the pivot point is lowered to ensure the reconstruction range. Therefore, proximal partial necrosis leading to surgery failure is sometimes caused by insufficient arterial supply if the flap is too long or the pivot point is too low and has no a reliable perforator in the pedicle. Herein, we describe a new method for extending the reconstruction range of the reverse sural neurofasciocutaneous flap that can provide a higher survival rate. METHODS: Between July 2010 and July 2014, 24 patients with forefoot defect were randomly assigned into two groups. In the research group, 12 modified reverse sural neurofasciocutaneous flaps with extended reconstruction range were used to reconstruct forefoot defect. We dissected the septum along the last perforator to locate the main trunk of the peroneal artery, disconnected the proximal end of the peroneal artery at the root of the perforator, and separated the peroneal artery more distally to obtain a lower rotation point to extend the reconstruction range. The last perforator and a section of the peroneal artery were contained in the pedicle. In the control group, 12 traditional reverse sural neurofasciocutaneous flap procedures were performed. RESULTS: In the research group, 11 flaps survived with good quality and esthetic contours. Partial distal necrosis occurred in 1 flap. In the control group, 7 flaps survived. Partial necrosis occurred in the other 5 flaps. Compared with control group, the survival rate in the research group was significantly higher while the healing time was significantly shorter. All patients were satisfied with the therapeutic outcome in the research group. CONCLUSIONS: Our modified method proved efficacious in extending the reconstruction range of the reverse sural neurofasciocutaneous flap. Meanwhile, partial necrosis was avoided because the length of the flap was shortened, and a reliable perforator was preserved in the artery pedicle.

An ulnar parametacarpal perforator flap for volar digital soft tissue reconstruction.

We present outcomes of using a perforator-based ulnar parametacarpal flap in 25 patients for digital pulp defects. These included 17 free transfers to the thumb, index, middle and ring fingers and eight reverse pedicled transfers to the little fingers. This flap includes a dorsal sensory branch of the ulnar nerve, which was sutured to the digital nerve in all transfers. Each flap had one to three reliable perforators (mean 0.44 mm diameter) to the ulnar parametacarpal region and contained at least one perforator within 2 cm proximal to the palmar digital crease. All the 25 flaps survived completely. Twenty-two patients were followed for 15 months (range 12 to 24), and three were lost to follow-up. The mean static and moving two-point discrimination of the flap was 7 mm and 5 mm, respectively. At the donor site, sensory reinnervation was acceptable. We conclude that ulnar parametacarpal perforator flaps offer sensate, thick and glabrous skin for finger pulp repair, all in a single operative field.Level of evidence: IV.

Could superior capsule findings be used as a predictor for partial bursal-sided rotator cuff tears?

PURPOSE: The purpose of this study was to investigate the relationship between the superior capsule tear patterns and synovitis with subacromial pathologies, such as bursal-sided rotator cuff tear and subacromial impingement syndrome. METHODS: Fifty patients who underwent arthroscopic treatment for isolated bursal-sided tear were included in the study. Fifty more patients who underwent arthroscopic treatment for isolated Superior Labrum Anterior Posterior (SLAP) 2 lesion without pathology in the rotator cuff were included in the control group. Firstly, superior capsule tear and common synovitis on the rotator cable were assessed during glenohumeral joint examination. Coracoacromial Ligament (CAL) degeneration grading was performed according to the Royal Berkshire Hospital classification. Bursal-sided partial tear grading was done using Ellman classification. Whether or not there was a relationship between synovitis, classic capsule tear, plus reverse flap capsule tear, and partial bursal-sided tear existence. RESULTS: There were 21 patients with reverse flap capsule tear in the study group and 3 patients in the control group. In addition, there were 13 patients with synovitis in the study group and 4 in the control group. Compared to the control group, there was also a significant positive correlation in the presence of both synovitis and reverse flap capsule tear with the presence of bursal-sided tear in the study group (p = 0.000). There was, however, no significant difference between the presence of classical capsule tear and the presence of bursal-sided tear (p = 0.485). CONCLUSION: This study shows that the presence of reverse flap capsule tear and synovitis was associated with partial bursal-sided tears. Therefore, if the reverse flap capsule tear or synovitis is detected in the superior capsule, the rotator cuff should be evaluated in more detail during subacromial bursoscopy in order not to miss a bursal-sided partial cuff tear.

Fenestrated Adipofascial Reverse Flap: A Modified Technique for the Reconstruction of Fingertip Amputations.

AIMS OF THE STUDY: Fingertip injuries can be treated in different ways, including shortening with primary closure, skin graft, and local or distant flaps. Several local flaps for the reconstruction of the amputated fingertip were described. We present our experience with a new concept of homodigital adipofascial reverse flap that avoids the second surgical stage and allows a complete and anatomically perfect reconstruction of nail bed, with preservation of the nail lamina. MATERIALS AND METHODS: Between March 2014 and February 2015, five patients with digital amputations (distally to the nail matrix) were treated using the Fenestrated Adipofascial Reverse (F.A.R.) flap. The patients were evaluated measuring 2-point discrimination (2PD) value and range of motion of the distal interphalangeal joint (DIP). Scar evaluation was performed using the Vancouver Scar Scale (VSS). RESULTS: All the flaps completely survived. A normal nail grow has been observed in first two-three months of post operatory follow-up. Length of the digits was preserved and good aesthetic as functional outcome were archive. The F.A.R. flap provided excellent coverage of fingertip defects and preserved finger length. After 1 year of follow, the mean static 2PD value at the reconstructed finger was 4.2 mm (range 3-5 mm), reconstructed fingers' mean range of motion for the DIP joint was 78 degrees and the VSS score ranged from 0 to 2 (mean score: 0.6). No complications were reported. CONCLUSIONS: F.A.R. flap is one of the most useful techniques in order to achieve all the goals in fingertip reconstruction.

Postoperative voluminal flap reduction after fingertip reconstruction using the reverse digital artery island flap.

A total of 16 fingers of 16 patients were subjected to fingertip reconstruction using the reverse digital artery island flap (RDAIF). We evaluated the influences of postoperative flap congestion, initial harvested flap size, patient's age and smoking habit on postoperative final flap size and postoperative range of total active motion (TAM) in affected fingers at a mean interval of 11.4 months. In the results, final flap size and TAM showed a tendency to decrease with increase in the initial harvested flap size and age. Eventually, the final flap size moved towards the size of the fingertip defect. Factors of flap congestion and smoking habit had little influence on the change in flap size and TAM. In conclusion, wide harvested flaps showed significant postoperative reduction in size compared with the small flaps, and extensive skin defect after flap harvest caused a decrease in postoperative TAM. Thus, the size of the harvested RDAIF should be comparable to that of the fingertip defect to prevent postoperative decrease in range of motion in affected fingers, and indication of this flap to the elderly needs to be considered.
