Computer-assisted surgery is the most significant recent advancement in osseous head and neck reconstruction. Computer-aided design (CAD) software allows computerized planning of resection and reconstruction. Computer-aided manufacturing (CAM) can be used to create models, cutting guides, and patient-specific plates. Several studies have shown that these techniques are more accurate and result in decreased flap ischemia times compared with conventional techniques. CAD also facilitates the immediate placement of dental implants. The most useful application of computer-assisted surgery is delayed reconstruction, in which soft tissue contraction and the absence of a specimen as a reference make accurate estimation of the defect challenging. The drawbacks of CAD/CAM are lack of intraoperative flexibility and cost. Some centers have created in-house CAD/CAM processes using open-source software and commercially available three-dimensional printers.

Face transplantation (FT) has emerged as a critical intervention for patients with complex facial deformities unsuitable for conventional reconstructive methods. It aims to restore essential functions such as facial expression, mastication, and speech, while also improving psychosocial health. The procedure utilizes various surgical principles, addressing unique challenges of craniofacial complexity and diverse injury patterns. The integration of Computerized Surgical Planning (CSP) leverages computer-aided technologies to enhance preoperative strategy, intraoperative navigation, and postoperative assessment. CSP utilizes three-dimensional computed tomography, printing, angiography, and navigation systems, enabling surgeons to anticipate challenges and reduce intraoperative trial and error. Through four clinical cases, including a groundbreaking combined face and bilateral hand transplant, CSP's role in FT is highlighted by its ability to streamline operative processes and minimize surgical revisions. The adoption of CSP has led to fewer cadaveric rehearsals, heightened operative precision, and greater alignment with preoperative plans. Despite CSP's advancements, it remains complementary to, rather than a replacement for, clinical expertise. The demand for technological resources and multidisciplinary teamwork is high, but the improved surgical outcomes and patient quality of life affirm CSP's value in FT. The technology has become a staple in reconstructive surgery, signaling a step forward in the evolution of complex surgical interventions.

Mandibular distraction osteogenesis is a technically challenging procedure due to complex mandibular anatomy, especially in the treatment of Pierre-Robin Sequence due to variable bone thickness in the infant mandible and the presence of tooth buds. Computerized surgical planning (CSP) simplifies the procedure by preoperatively visualizing critical structures, producing cutting guides, and planning distractor placement. This paper describes the process of using CSP to plan mandibular distraction osteogenesis, including discussion of recent advances in the use of custom distractors.

Craniosynostosis, a medical condition characterized by premature fusion of one or multiple cranial sutures, has historically been treated through surgical correction. Computerized Surgical Planning (CSP) and three-dimensional (3D) modeling have gained significant popularity across craniofacial surgery. Through a collaborative effort between surgeons and engineers, it is now possible to virtually execute a surgical plan based on preoperative imaging using computed tomography scans. The CSP workflow involves several elements including virtual 3D modeling, CSP computer-aided surgical guide design, manufacturing of guides and templates, and intraoperative implementation. Through the gradual optimization of this workflow, it has been possible to achieve significant progress in the surgical process including improvements in the preoperative planning of complex craniosynostosis cases and reduction of intraoperative time. Furthermore, CSP and 3D modeling have had a positive impact on surgical simulation and residency training, along with patient education and counseling. This article summarizes the CSP workflow in the treatment of craniosynostosis and the implications of this treatment modality on medical trainee education and patient management.

Computerized Surgical Planning (CSP) is a surgical tool that enables precise bony changes through the creation of custom cutting guides and/or custom plates. CSP has been shown to be a safe and effective tool in gender affirming facial surgery as well, specifically with regard to frontal sinus setback, zygomatic remodeling, genioplasty, and mandibular angle and body reshaping. CSP aids in trainee education, improves symmetry, reduces operative time, and can produce idealized results during complex revisions. Overall, CSP is a valuable tool in the field of gender affirming facial surgery that helps surgeons achieve optimal aesthetic and safety outcomes for patients.

Airway management in both acute and reconstructive burn patients can be a major challenge for evaluation, intubation, and securing the airway in the setting of altered airway structure. Airway evaluation in both acute and reconstructive patients includes examination for evidence of laryngeal and supraglottic edema and structural changes due to trauma and/or scarring that will impact the successful approach to acquiring an airway for surgical procedures and medical recovery. The approach to acquiring a successful airway is rarely standard laryngoscopy and often requires fiberoptic bronchoscopy and a variety of airway manipulation techniques. Tracheostomy should be reserved for those with classic requirements of ventilatory and/or mechanical failure or severe upper airway burns. Even securing an airway for surgical procedures, especially with patients suffering injuries involving the head and neck, can be nonstandard and requires creative and flexible approaches to be successful. After much trial and error over the past 30 years in a large burn center, our multidisciplinary team has learned many valuable lessons. This review will focus on our current approach to safe airway management in acute and reconstructive burn patients.

Contrary to prior pediatric burn treatment philosophies, we now know that early burn excision and grafting for non life-threatening burns can compromise future reconstruction. Extensive scar excision should be minimized and scar rehabilitation maximized, as secondary iatrogenic deformities can become even more difficult to fix. Scar remodeling with local tissue rearrangement can relieve tension and soften scars over time. The majority of facial burns often only involve skin and can be adequately treated without the need for complex flap reconstruction. Facial burn scars are a different problem than facial burn scar contracture. The former needs scar rehabilitation, whereas the latter needs the addition of skin. Laser therapy has transformed the treatment of burn scars and is an incredibly valuable adjunct to local tissue rearrangement and grafting. The most favorable functional, aesthetic, and psychological outcomes require a long-term multidisciplinary effort and customized protocol utilizing the vast armamentarium of reconstructive tools described below.
