BACKGROUND: Breast reconstruction after cancer surgery through lipomodeling can be performed alone or in combination with a flap. Our objective is to describe the proportion of techniques used on patients who underwent autologous reconstructive surgery after tumorectomy or mastectomy in Franche-Comté.
METHODS: A bicentric retrospective observational study was conducted between October 2017 and December 2021 (NCT06101732), including three groups: those who underwent exclusive lipomodeling reconstruction after mastectomy (1) or in addition to a flap (2), and those who underwent exclusive lipomodeling reconstruction after tumorectomy (3). Socio-demographic, medical, and surgical data were collected and recorded in a specially designed software.
RESULTS: Two hundred and fifty-one lipomodeling procedures were performed on 91 patients. In group 1, the average transferred volume was 1191mL with an average number of sessions of 4.4 spreads over 19.4months. In group 2, the average transferred volume was 676mL with an average operative time of 2.5 spread over 16.1months. In group 3, the average transferred volume was 223mL with an average number of sessions of 1.5 spreads over 6.2months. Regarding postoperative complications, 11% had cysts of fat necrosis, 4.4% had infections, and 2.2% had hematomas.
CONCLUSIONS: Lipomodeling is a technique that has clearly established itself in the field of breast reconstructive surgery. It results in a few complications and improves the final aesthetic outcome whether used exclusively or in addition to a flap.

The management of head and neck cancers is multidisciplinary, often relying on the use of combined treatments to maximize the chances of cure. Combined treatments are however also responsible for cumulative side effects. The aim of reconstructive surgery with a flap is to restore a function lost with the loss of substance from the tumor resection. However, changes in reconstructive surgery have impact of postoperative radiotherapy planning. The optimization of imaging protocols for radiotherapy planning should make it possible to identify postoperative changes and to distinguish flaps from surrounding native tissues to delineate the flaps and document the spontaneous evolution of these flaps or dose-effect relationships in case of radiotherapy. Such changes include atrophy, fibrosis of soft tissue flaps and osteoradionecrosis of bone flaps. Radiotherapy optimization also involves standardization of the definition of target volumes in situations where a flap is present, a situation that is increasingly common in routine care. This evolution of practice, beyond the essential multidisciplinary consultation meetings defining treatment indications, requires a close radio surgical collaboration with respect to technical aspects of the two disciplines. Doing so, anticipation of relapse and toxicity profiles could possibly lead to propose strategies for personalized de-escalation of multimodal treatments through interdisciplinary trials.

The shape modified radial forearm flap was developed by the late Dr. Musa Mateev. This type of propeller flap has many benefits, especially for donor site morbidity. However, it is not currently widely used for the coverage of hand defects. Therefore, we will describe the Dr. Mateev technique including a demonstrative video of our experience in remembrance of Dr. Mateev and his brilliant work with upper limb reconstruction.

OBJECTIVE: This study aimed to demonstrate the efficacy of sildenafil citrate in order to improve the distal necrosis of randomized flaps in diabetic rats, and to explore new methods to reduce distal necrosis encountered in flap surgery.
METHODS: This is an experimental study in rats. The rats were first divided into three groups: Control(C), Diabetes(D), and Sildenafil(S). Streptozotocin 40mg/kg was administered intraperitoneally to the rats in groups D and S that would develop diabetes. Two days after the procedure, blood glucose was measured from the tail vein of the rats, and the rats with a blood glucose level of 250mg/dL and above were considered diabetic. 7×3cm McFarlane flap was randomly planned on the back of the rats. In the flaps, ischemia was measured at the 30th minute with Na fluorescein, flap necrosis was measured on days 4 and 7, and specimens were collected from the critical zone and distal zone regions for histological examination.
RESULTS: The comparison of ischemia and necrosis regions, ischemia was found to be more significant in groups D and S compared to group C (P<0.05). In the comparison of necroses on days 4 and 7, it was determined that necrosis occurred significantly (P<0.05) less in group S compared to the other groups. It was determined that necrosis in group D was significantly (P<0.05) higher on days 4 and 7 compared to the other groups.
CONCLUSIONS: The distal circulation is affected worse in randomized flaps in diabetes. Sildenafil citrate significantly increased the flap viability (P<0.05).

OBJECTIVE: The resection of malignant bone tumors of the pelvis causes significant loss of substances making covering procedures difficult. The gluteus maximus pedicled flap allows some reconstructions, but its use in vascular sacrifice is not clearly established. The objective of our study was to study its vascularization in order to assess the possibility of vascular sacrifice during carcinological resection of a pelvic tumor.
METHODS: We first performed a vascular mapping of the gluteus maximus muscle using 3-dimensional (3D) models from CT angiography in patients with Leriche syndrome. These models were compared to a cadaveric dissection of 2 injected muscles. A second 3D modeling from postoperative scans was performed in patients who had a gluteus maximus flap after pelvic carcinological surgery.
RESULTS: Ten patients with Leriche syndrome had a 3D model from their scanners. Three distinct arterial systems were identified. Seven patients had a flap from the gluteus maximus muscle, including 3 cases of an Inverted pedicled Hemi Gluteus maximus flap (HGI). According to the modeling, the richness of the vascular network would allow the sacrifice of the superior gluteal pedicle without compromising the viability of this flap.
CONCLUSIONS: Our study made it possible to confirm the richness of the vascular network of the gluteus maximus muscle and to consider the theoretical possibility of sacrificing the superior gluteal pedicle without endangering an HGI pedicled muscle flap.

Coverage of soft tissue defects in the thumb involves a variety of techniques ranging from simple second-intention healing to skin grafting with or without dermal substitutes, to local homodigital or heterodigital flaps and partial toe transfers. The arsenal in terms of skin coverage and especially flaps is very diverse. Our objective is not to make an exhaustive catalog of all the technical possibilities described in the literature, but rather to present in detail the options we have adopted in our daily practice. For each of these techniques, we present the rules for their implementation (anatomical bases, surgical techniques) and their topographical indications.

The tracheostomy procedure presents some long term complications such as the depressed scar. It can be responsible for a tracheal tug, invaginated scar, inaesthetic scar or all of them. No consensus has emerged in the treatment of this type of pathological scarring. We want to propose a new surgical approach to correct all these three pathological scarring mechanism by a subcutaneous flap in single operation.

BACKGROUND: The management of bone exposure in patients with extensive burns could be a challenge due to the lack of healthy tissue. In such cases, it could be interesting to use any still healthy tissue initially destined for amputation and use it to cover up another site. We present the case of a sever burn patient for whom we used the only healthy palmar hand skin to cover an olecranon exposure.
UNASSIGNED: A 38-year-old man has been admitted in burn victim unit with extensive deep burns on 60% of the total body surface. An exposure of the left olecranon was appeared occurring on a burned area, with absence of healthy local tissues available for coverage. Concomitantly a trans-radial amputation was indicated because of severe digits burns leading to an impossibility to preserve the function of the hand. A palmar skin area was healthy leading to harvested this palmar skin flap pedicled on ulnar vessels. Early post-operative healing was satisfactory and no vascular suffering of the flap has been observed with a total healing at three weeks.
CONCLUSIONS: In any patient the spare tissues concept should be keep in mind when amputation is indicated simultaneously with a problematic of loss of substance coverage to a proximity area. In this case of severe burn patient, we used a palmar skin flap pedicled on the ulnar vessels to cover an olecranon exposure.

Ulnar tunnel syndrome is the second most common upper-limb peripheral nerve compression syndrome. Recurrence or persistence of symptoms after primary surgery is found in 9.9%-21% of cases. The main cause of failure is peri- and endo-neural fibrosis, and management is difficult and controversial. Revision of nerve neurolysis combined with freestyle adipofascial flap provides nerve decompression and coverage with vascularized tissue, which prevents scar tissue formation around the nerve and restores glide. We performed a preliminary vessel-injected cadaver study. The perforating vessels from the posterior recurrent ulnar artery vascularize the medial adipose and fascial tissues of the elbow, allowing elevation of an adipofascial flap which is able to reach the ulnar nerve. Eight patients with neuropathic ulnar nerve pain in recalcitrant ulnar tunnel syndrome due to peri- and/or endo-neural fibrosis were treated by neurolysis, and the nerve was covered with an ulnar adipofascial flap. All patients were evaluated by percussion test, visual analog scale for pain, electromyography, electroneurography and ultrasound, and were classified according to the McGowan classification as modified by Goldberg. The study was approved by the review board. All patients had good 4-year outcome, with complete return to daily activity, work and sports 4 months after surgery. The results of this novel surgical technique were encouraging, without complications or donor site morbidity. Adipofascial flap combined with neurolysis could be a valid solution in the treatment of recalcitrant ulnar tunnel syndrome.
