To ascertain the precision and dependability of augmented reality (AR) technology in pinpointing perforating vessels of the posterior tibial artery during the surgical reconstruction of lower limb soft tissue defects using the posterior tibial artery perforator flap.
Ten patients, during the period from June 2019 to June 2022, benefited from ankle skin and soft tissue repair through the application of the posterior tibial artery perforator flap. A group of 7 males and 3 females, with an average age of 537 years (mean age range: 33-69), was observed. Traffic incidents led to injuries in five cases, four cases involved injuries from being hit by heavy objects, and machinery caused one injury. Wound sizes, in terms of area, exhibited a spectrum ranging from 5 cm by 3 cm to 14 cm by 7 cm. The period spanning from the occurrence of the injury until the surgical intervention ranged from 7 to 24 days, with an average duration of 128 days. Pre-operative CT angiography was performed on the lower limbs, and the outcome data facilitated the three-dimensional reconstruction of perforating vessels and bones employing the Mimics software. With the aid of augmented reality, the above images were projected and superimposed onto the surface of the affected limb, and the skin flap was subsequently designed and resected with utmost precision. The flap exhibited a size fluctuation from a minimum of 6 cm by 4 cm to a maximum of 15 cm by 8 cm. Either a skin graft or direct sutures were applied to the donor site's repair.
Employing an augmented reality (AR) approach, the 1-4 perforator branches of the posterior tibial artery (a mean of 34 perforator branches) were located preoperatively in 10 patients. The operative placement of perforator vessels essentially mirrored the pre-operative AR data. The distance between the two sites displayed a range from 0 to 16 millimeters, achieving an average distance of 122 millimeters. In accordance with the preoperative plan, the flap was successfully collected and mended. Despite the potential for vascular crisis, nine flaps remained unaffected. In a review of cases, local skin graft infections were identified in two cases, and distal flap edge necrosis was present in a singular case, healing successfully following dressing changes. Integrated Immunology Though some grafts were lost, the skin grafts that did survive healed the incisions by first intention. Each patient's health was observed for a span of 6 to 12 months, producing an average of 103 months of follow-up. Softness of the flap was assured by the lack of apparent scar hyperplasia and contracture. At the final follow-up, the American Orthopaedic Foot and Ankle Society's (AOFAS) scoring system documented excellent ankle function in 8 cases, good ankle function in 1 case, and poor ankle function in 1 case.
Augmented reality (AR) can be employed in the preoperative planning of posterior tibial artery perforator flaps to precisely identify perforator vessel locations, thereby diminishing the risk of flap necrosis, and simplifying the surgical process.
The preoperative planning of posterior tibial artery perforator flaps can leverage AR technology to pinpoint perforator vessel locations, thereby minimizing flap necrosis risk, and simplifying the surgical procedure.
The harvest process of the anterolateral thigh chimeric perforator myocutaneous flap, including its combination methods and optimization strategies, is examined in detail.
A retrospective analysis of clinical data was conducted on 359 oral cancer cases admitted to the facility between June 2015 and December 2021. A total of 338 males and 21 females showed an average age of 357 years, with ages ranging between 28 and 59 years. 161 cases of tongue cancer, 132 instances of gingival cancer, and 66 cases of buccal and oral cancer were observed. T-stage cancer cases totaled 137, as per the Union International Center of Cancer's (UICC) TNM staging.

The illness's course lasted between one and twelve months, having a mean of sixty-three months. The repair of the soft tissue defects, left behind with dimensions ranging from 50 cm by 40 cm to 100 cm by 75 cm after radical resection, was performed using free anterolateral thigh chimeric perforator myocutaneous flaps. The myocutaneous flap was harvested through a process principally divided into four steps. RP-6685 purchase In the initial step, the perforator vessels, primarily sourced from the oblique and lateral branches of the descending branch, were identified, isolated, and then separated. To isolate the main perforator vessel pedicle and ascertain the muscle flap's vascular pedicle's origin (oblique branch, lateral descending branch, or medial descending branch) constitutes step two. Determining the source of the muscle flap, including the lateral thigh muscle and rectus femoris, constitutes step three. The fourth step in the process involved defining the harvesting strategy for the muscle flap, which included characterization of the muscle branch type, the distal segment type of the main trunk, and the lateral segment type of the main trunk.
Free chimeric perforator myocutaneous flaps from the anterolateral thigh were gathered: 359 in total. Without exception, the anterolateral femoral perforator vessels were observed in each of the instances reviewed. The flap's perforator vascular pedicle, originating from the oblique branch, was observed in 127 patients, contrasted with 232 patients where the lateral branch of the descending branch served as the vascular source. A vascular pedicle originating from the oblique branch was observed in 94 muscle flap specimens; in 187 specimens, the pedicle arose from the lateral branch of the descending branch; and in 78 specimens, the medial branch of the descending branch provided the pedicle. A surgical technique for collecting muscle flaps used the lateral thigh muscle in 308 cases and the rectus femoris muscle in 51 cases. Cases of harvested muscle flaps included 154 examples of the muscle branch type, 78 examples of the distal main trunk type, and 127 examples of the lateral main trunk type. In terms of size, skin flaps displayed a range from 60 cm by 40 cm to 160 cm by 80 cm, while muscle flaps exhibited a range from 50 cm by 40 cm to 90 cm by 60 cm. In 316 instances, the perforating artery was found to anastomose with the superior thyroid artery, while the accompanying vein likewise anastomosed with the superior thyroid vein. The perforating artery, in 43 cases, formed an anastomosis with the facial artery, while the accompanying vein exhibited a corresponding anastomosis with the facial vein. Six patients presented with hematomas following the surgical intervention, and four showed signs of vascular crisis. After emergency exploration, 7 cases were saved successfully; in one, a partial skin flap necrosis was observed, which healed with conservative dressing changes. Two other cases experienced complete necrosis of the skin flap, necessitating repair with a pectoralis major myocutaneous flap. All patients' follow-up spanned from 10 to 56 months, with a mean follow-up period of 22.5 months. Satisfactory was the assessment of the flap's appearance, while swallowing and language functions were also restored to a satisfactory state. The donor site's sole remnant was a linear scar, and no adverse effects were observed on the thigh's function. sexual transmitted infection Further monitoring of the patients uncovered 23 instances of local tumor recurrence and 16 instances of cervical lymph node metastasis. The three-year survival rate was an extraordinary 382 percent, with 137 patients surviving from an initial group of 359.
