Inferiorly Pedicled Nasolabial Flap for Reconstruction of Anterior Maxilla Defects Class I and II

Engineered organoids in oral and maxillofacial regeneration

Oral and maxillofacial organoids, as three-dimensional study models of organs, have attracted increasing attention in tissue regeneration and disease modeling. However, traditional strategies for organoid construction still fail to precisely recapitulate the key characteristics of real organs, due to the difficulty in controlling the self-organization of cells in vitro. This review aims to summarize the recent progress of novel approaches to engineering oral and maxillofacial organoids. First, we introduced the necessary components and their roles in forming oral and maxillofacial organoids. Besides, we discussed cutting-edge technology in advancing the architecture and function of organoids, especially focusing on oral and maxillofacial tissue regeneration via novel strategy with designed cell-signal scaffold compounds. Finally, current limitations and future prospects of oral and maxillofacial organoids were represented to provide guidance for further disciplinary progression and clinical application to achieve organ regeneration.

Reconstruction using facial artery system-based flaps. One vascular system for multiple purposes in head and neck reconstructive surgery

INTRODUCTION

to review the modifications and advances in reconstructive surgery of the soft tissues of the oral cavity exclusively based on flaps that depend on the facial artery system.

METHODS

review of the literature regarding oral cavity reconstructions based on main facial artery system flaps.

DISCUSSION

The reconstruction of the soft tissues of the oral cavity, based on facial artery system flaps, offers satisfactory results and allows limited reconstructions avoiding the use of pedicled regional flaps or free flaps.

CONCLUSIONS

Knowledge of reconstructive options using the facial artery system in oral cavity surgery allows expanding reconstructive options for head and neck surgeons, enabling safe, high quality and effective reconstructions, with limited resources consumption.
