Unlike unwounded healthy volunteers, a significant increase in indocyanine green angiography perfusion was found in chronic-wound patients immediately after therapy (p < 0.03). Moreover, the authors found that 100 percent of the wounds that demonstrated improved perfusion from session 1 to session 2 went on to heal within 30 days of hyperbaric oxygen therapy completion, compared with none in the subgroup that did not demonstrate improved perfusion (p < 0.01). This study demonstrates a beneficial impact of hyperbaric oxygen therapy on perfusion in chronic wounds by ameliorating hypoxia and improving angiogenesis, and also proposes a potential role for indocyanine green angiography in early identification of those who would benefit the most from hyperbaric oxygen therapy.

The anterolateral thigh flap is one of the most useful workhorse flaps for microsurgical reconstruction. However, it can pose a great challenge to surgeons because of its anatomical variability. As the technology advances, not only septocutaneous or musculocutaneous courses of anterolateral thigh perforators but also a hybrid musculoseptocutaneous perforator pattern have been identified on computerized imaging and on cadaveric study. However, there is a paucity of clinical study in the literature. The aim of this investigation was to identify the features of this pattern.

All patients undergoing anterolateral thigh flap harvest between September of 2017 and May of 2018 performed by a single surgeon are included. Every pulsatile perforator was dissected to document its location on the thigh, emerging location (septum/muscle), size, course, and origin.

Thirty-seven patients with 115 perforators were identified. Ten percent of perforators were septocutaneous, 37 percent were musculoseptocutaneous, and 52 percent were musculocutaneous. Forty-seven percent of perforators emerged on the septum between the rectus femoris and the vastus lateralis. Eighty-one percent of patients had one or more perforators in the "hot zone." Medium and large perforators were more frequently located in the proximal and hot zones. All perforators originated from the vascular tree of the lateral circumflex femoral artery, with 10 percent originating from the transverse branch, 28 percent originating from the oblique branch, and 62 percent originating from the descending branch.

A high proportion of musculoseptocutaneous perforators were identified. The clinical relevance of this is to be very cautious on the skin paddle design while harvesting the flap.

Gender-affirming surgery is becoming increasingly more common. ABT-199 ic50 Procedures including chest masculinization, breast augmentation, vaginoplasty, metoidioplasty, and phalloplasty routinely generate discarded tissue. The incidence of finding an occult malignancy or premalignant lesion in specimens from gender-affirming surgery is unknown. The authors therefore conducted a retrospective review of all transgender patients at their institution who underwent gender-affirming surgery to determine the incidence of precancerous and malignant lesions found incidentally.

A retrospective review of transgender patients who underwent gender-affirming surgery at the authors' institution between 2017 and 2018 performed by a single plastic surgeon and a single reconstructive urologic surgeon was conducted. Only transgender patients who underwent gender-affirming surgery that led to routine pathologic review of discarded tissue (mastectomy, vaginoplasty, vaginectomy as part of phalloplasty) were included. Charts were reviewedto care. The authors' review of routine pathologic specimens generated from gender-affirming surgery yielded a 6.4 percent rate of finding atypical lesions requiring further evaluation. The authors advocate that all specimens be sent for pathologic evaluation.

Umbilical reconstruction is a procedure with widespread indications in the setting of congenital or postsurgical loss. Reconstruction of the umbilicus when no remnant of the natural umbilicus is present is also called neoumbilicoplasty. Numerous neoumbilicoplasty techniques have been published, including cartilage grafts, full-thickness skin grafts, and multiflap reconstruction. No consensus has been reached regarding an optimal technique, and many procedures involve complicated designs with small flaps that are difficult to reproduce or explain. The authors divide patients into three types depending on the thickness of the adipose layer of the abdomen. With appropriate patient selection and minor variations depending on patient type, the technique can be applied to all patients. The umbilicus is marked in the appropriate position. Local anesthesia is infiltrated, and the area beneath the skin is defatted. The dermis is then applied to the underlying fascia with a superior shift. The authors describe the tee achieves those goals. It can be performed under local anesthetic and with a simple occlusive dressing so that the patient can go on with most of his or her daily activities. There is no scar to suggest a surgical procedure, and patients are extremely happy with the aesthetic outcomes.

In an ongoing effort to understand the pathogenesis of occipital neuralgia/headache/migraine, it is critical to describe the anatomical/tissue changes encountered during surgery. Greater occipital nerve anatomical studies mainly focus on the greater occipital nerve course through muscle/fascial planes and interaction with the occipital vessels. However, structural soft-tissue changes have not been described in detail. Anecdotally, trapezius fascia is thickened at the greater occipital nerve trigger site. This study further investigates this observation. Patients undergoing greater occipital nerve decompression surgery were enrolled prospectively in this observational study (n = 92). Tissue changes were recorded intraoperatively. The resulting data were examined. Trapezius fascia was more than 3 mm thick and appeared fibrotic in 86 patients (94 percent), whereas semispinalis muscle appeared normal in all subjects. The greater occipital nerve was macroscopically abnormal, defined as edematous, flattened, and discolored in 29 cases (32 percent).
