Article Abstract
Background: The utilization of an arteriovenous loop is an underreported technique that affords the creation of reliable vascular options. Understanding the efficacy and impacting variables of microvascular reconstruction with an arteriovenous loop can be critical to its use.
Methods: Multi-institutional study of 36 patients who underwent vein grafting or AV loop with free tissue transfer.
Results: 58.3% of patients received prior radiation and 38.9% prior flap reconstruction. Flap success for vein grafting was 76% and AV loop was 100% (p = 0.16). Success for the radiated cohort was 90.5% and non-radiated 80% (p = 0.63). Flap success for the radiated, vein grafted patient was 83.3% and 100% flap success rate for radiated, AV loop patient (p = 0.49). Overall flap survival was 83.3% versus 97% overall success rate in the United States.
Conclusion: The AV loop is a viable modality for vessel-depleted free tissue reconstruction. Radiation and previous surgery do not significantly impact flap success rates.

A 12-year-old neutered male pit bull crossbreed dog was presented because of a right caudal maxillary swelling. Computed tomographic imaging of the skull and revealed a right maxillary mass with lysis of the medial wall of the right orbit and rostral aspect of the zygomatic bone. A biopsy was done, and histopathology results were consistent with a mixed odontogenic tumor.

Reconstruction of the calcaneal region presents unique challenges due to its complex anatomy and critical weight-bearing function. This retrospective study aims to report our experience in cases of calcaneal defects repaired with various free flap types, and to evaluate the long-term outcomes of the reconstructions. We retrospectively reviewed 25 patients who underwent microsurgical free flap reconstruction for calcaneal defects between January 1997 and March 2022.

Background: Furcation involvement (FI) in multi-rooted teeth poses significant challenges in periodontal therapy due to complex anatomy and difficulty in achieving effective maintenance. FI is associated with increased periodontal destruction, especially in sites with narrow furcation entrances and deep root concavities. These features hinder effective debridement and compromise the efficacy of periodontal treatments.

The advancement of science and technology is an undeniable phenomenon that is progressively transforming all aspects of human life, including scientific, social, humanitarian, and environmental fields, among others. Facial reconstruction surgery has recently gained much attention owing to the incorporation of new technologies, such as bioprinting, regenerative medicine (RM), and artificial intelligence (AI) in surgery. These advancements have led to more innovative, site-specific, and optimal methods of addressing the challenges of facial reconstruction following trauma, congenital malformations, and oncological resections.

Reconstruction of large full-thickness medial lower eyelid margin defects often requires centrally-based tarsoconjunctival pedicle flaps from the ipsilateral upper eyelid in combination with anterior lamellar grafting. However, centrally-based flaps may result in temporary obstruction of the visual axis in the affected eye. We present a novel modified surgical technique utilizing a medially-based tarsoconjunctival pedicle flap from the upper eyelid for the reconstruction of large full-thickness medial lower eyelid defects.
