Salvage Treatment in Cleft Lip and Palate Surgeries

Cleft lip and palate surgeries demand a surgeon's expertise and a delicate touch to prevent potential devastating conditions. This study group will commence with a brief introduction to the treatment algorithm for oronasal fistula, followed by an examination of a case marked by a regrettable outcome due to an ill-advised decision during cleft orthognathic surgery. The execution of segmental osteotomy to align the upper dental arch led to necrosis in the adjacent alveolar bone and gingival tissues. Ultimately, an alveolar oronasal fistula occurred, resulting in the loss of a tooth. This section will delve into the decision-making process for aligning the dental arch in cleft cases and explore salvage procedures for such conditions. Moderators within this study group will also share intriguing cases for collective discussion. 

Speakers: Dr Ting-Chen Lu, Dr Pramila Shakya, Dr Juna Gurung.

Orthognathic Surgery in TMJ Patients

In this AO CMF Study Club session, Tal Yoffe gives a presentation focusing on Orthognathic Surgery in TMJ Patients. Florian Thieringer and Ariel Hirschhorn moderate the online discussion.

Maxilla and Mandible Bimaxillary Orthognathic and Obstructive Sleep Apnea Surgery LeFort I Osteotomy and Bilateral Sagittal Split Osteotomy (BSSO)

In this exercise, the procedure for the LeFort I osteotomy in the maxilla, and the bilateral sagittal split osteotomy (BSSO) in the mandible on an anatomical specimen will be demonstrated.
Learning objectives:
Describe the anatomical landmarks and surgical approach for the Le Fort I osteotomy and the BSSO.
Define the position and technique of the osteotomies necessary to avoid damage to the tooth roots and neurovascular structures.
Explain the steps for mobilization and fixation of the bone fragments necessary to avoid complications.
Speaker: Giovanni Gerbino.

Advanced Craniomaxillofacial Surgery. Tumor, Corrective Bone Surgery and Trauma

Co-authored by Michael Ehrenfeld, Neal Futran, Paul N Manson and Joachim Prein.

Featuring more than 1,100 expertly drawn illustrations and images, the Advanced Craniomaxillofacial Surgery book is the comprehensive, highly anticipated follow-up to the original work on Principles of Internal Fixation of the Craniomaxillofacial Skeleton that was published in 2012.

With detailed contributions from more than 80 renowned international authors, Advanced Craniomaxillofacial Surgery significantly builds on the solid foundation laid by the previous textbook. The book comprises sophisticated techniques in skeletal and soft-tissue analysis for the disciplines of craniomaxillofacial, trauma, tumor, orthognathic surgery, as well as facial and esthetic surgery.

The advent of microvascular surgery, skeletal analysis, computerized surgical planning, personalized implant creation, and comprehensive radiographic analysis have given rise to new principles, techniques and possibilities, which are explored extensively in this new textbook. Advanced Craniomaxillofacial Surgery should be part of every surgeon's library.

Principles of Internal Fixation of the Craniomaxillofacial Skeleton – Trauma and Orthognathic Surgery 

Co-authored by Joachim Prein, Michael Ehrenfeld, and Paul N Manson

The principles described in this textbook represent the evolution of craniomaxillofacial buttress reconstruction over the last 60 years. In addition to standard procedures, techniques representing recent surgical advances and new developments are introduced as well. This textbook not only provides an overview on current concepts of craniomaxillofacial trauma care and orthognathic surgery, but also helps to understand the complexity of the craniofacial skeleton and its related soft tissues for an efficient and successful reconstruction of the face following trauma and congenital deformities.
