Assessing the precision and robustness of augmented reality (AR) procedures for pinpointing perforating vessels of the posterior tibial artery in treating soft tissue defects of the lower limbs using the posterior tibial artery perforator flap method.
In ten cases, the posterior tibial artery perforator flap was employed to address defects in the skin and soft tissues adjacent to the ankle between June 2019 and June 2022. The group included 7 male and 3 female individuals, with an average age of 537 years; a range in age of 33-69 years. Injuries resulting from traffic accidents occurred in five cases, in four cases heavy objects led to bruising, and a machine was the cause in a single case. Wounds presented a dimension range, with the smallest wound measuring 5 cm by 3 cm and the largest 14 cm by 7 cm. A period of 7 to 24 days, with an average of 128 days, separated the injury from the scheduled surgical procedure. Before the operation, CT angiography was carried out on the lower limbs; subsequently, the gathered data allowed for the creation of three-dimensional images of perforating vessels and bones with the aid of Mimics software. The skin flap's design and resection were guided by the precise positioning provided by the augmented reality projection of the above images onto the surface of the affected limb. There was a range in the flap's size, starting at 6 cm by 4 cm and extending up to 15 cm by 8 cm. Skin grafting or direct sutures were used to repair the donor site.
Augmented reality (AR) technology facilitated the preoperative localization of the 1-4 perforator branches of the posterior tibial artery (mean 34 perforator branches) in a cohort of 10 patients. The consistency of perforator vessel location during surgery was largely in line with the pre-operative AR data. The gap between the two locations ranged from a minimum of 0 mm to a maximum of 16 mm, with a mean separation of 122 mm. The flap, having undergone a successful harvest and repair, conformed precisely to the pre-operative blueprint. Undaunted by the threat of vascular crisis, nine flaps thrived. Two instances of local skin graft infection occurred, along with one instance of distal flap edge necrosis. This necrosis subsided after a dressing change was administered. porous medium The survival of the other skin grafts was accompanied by the first-intention healing of the incisions. Patients were monitored for 6-12 months, yielding an average follow-up time of 103 months. The flap maintained its softness, with no discernible scar hyperplasia or contracture present. In the final follow-up report, the American Orthopedic Foot and Ankle Society (AOFAS) score showed the ankle function to be excellent in eight instances, good in one, and poor in one instance.
Utilizing augmented reality (AR) in preoperative planning for posterior tibial artery perforator flaps enables precise identification of perforator vessel locations. This approach can mitigate the risk of flap necrosis and simplify the surgical technique.
AR technology facilitates preoperative planning for posterior tibial artery perforator flaps by precisely locating perforator vessels. This leads to a reduced risk of flap necrosis, and a more straightforward operative technique.
We review the diverse combination methods and optimization strategies used in the procedure of harvesting anterolateral thigh chimeric perforator myocutaneous flaps.
A review of clinical data from 359 patients diagnosed with oral cancer and admitted between June 2015 and December 2021 was performed retrospectively. Thirty-three eight males and twenty-one females, with an average age of three hundred fifty-seven years, ranged in age from twenty-eight to fifty-nine years. 161 cases of tongue cancer, 132 instances of gingival cancer, and 66 cases of buccal and oral cancer were observed. UICC TNM staging statistics indicated 137 cases associated with T-stage tumors.

The illness's course lasted between one and twelve months, having a mean of sixty-three months. Following radical resection, free anterolateral thigh chimeric perforator myocutaneous flaps were utilized to repair the soft tissue defects, ranging in size from 50 cm by 40 cm to 100 cm by 75 cm. The myocutaneous flap acquisition procedure was primarily compartmentalized into four stages. Biosensing strategies To begin, the perforator vessels, originating for the most part from the oblique and lateral branches of the descending branch, were exposed and separated. To successfully proceed with the procedure, step two mandates the isolation of the main trunk of the perforator vessel pedicle and the determination of the origin of the muscle flap's vascular pedicle—either the oblique branch, the lateral descending branch, or the medial descending branch. The third step in the process identifies the source of the muscle flap, encompassing both the lateral thigh muscle and rectus femoris. In step four, the muscle flap's harvest configuration was determined, including specifications for the muscle branch type, the distal component of the main trunk, and the lateral component of the main trunk.
359 free anterolateral thigh chimeric perforator myocutaneous flaps were obtained through a surgical procedure. All cases showed the presence of anterolateral femoral perforator vessels. In 127 instances, the perforator vascular pedicle of the flap originated from the oblique branch, while the lateral branch of the descending branch provided the source in 232 cases. A vascular pedicle of a muscle flap originated from the oblique branch in 94 cases; 187 cases saw origination from the lateral branch of the descending branch; and in 78 cases, origination was from the medial branch of the descending branch. A surgical technique for collecting muscle flaps used the lateral thigh muscle in 308 cases and the rectus femoris muscle in 51 cases. The harvest comprised 154 muscle flaps of the muscle branch variety, 78 muscle flaps of the distal main trunk variety, and 127 muscle flaps of the lateral main trunk variety. A gradation in skin flap sizes was observed, varying from 60 cm by 40 cm to 160 cm by 80 cm, and the dimensions of muscle flaps exhibited a similar gradation from 50 cm by 40 cm to 90 cm by 60 cm. In 316 cases, an anastomosis between the perforating artery and the superior thyroid artery was present, alongside an anastomosis between the accompanying vein and the superior thyroid vein. 43 instances of arterial anastomosis linked the perforating artery to the facial artery, and venous anastomosis connected the accompanying vein to the facial vein. After the operation, a total of six patients demonstrated hematoma formation and four developed vascular crises. Among the cases reviewed, seven were successfully salvaged after emergency exploration. One case presented with partial skin flap necrosis, responding favorably to conservative dressing management, and two cases displayed complete necrosis, requiring repair via a pectoralis major myocutaneous flap procedure. Patients underwent follow-up evaluations ranging from 10 to 56 months, with an average duration of 22.5 months. The flap's appearance was judged satisfactory, and both swallowing and language functions were completely restored. The donor site exhibited only a linear scar, and no noticeable impairment to the thigh's function resulted. EX 527 cost In the follow-up assessment, 23 patients encountered local tumor recurrence and 16 patients presented with cervical lymph node metastasis. The survival rate for three years was 382 percent, specifically 137 out of 359 patients.
