Department of Oral and Maxillofacial Surgery; Bruce Rappaport Faculty of Medicine, Technion-Israel Institute of Technology, Haifa, Israel.

Maxillary hypoplasia is a common outcome in patients with cleft lip and palate after surgical and orthodontic interventions, and maxillary distraction osteogenesis has become a useful procedure for patients with extensive maxillary deformities. The aim of this study was to evaluate long term (two years) stability after maxillary advancement of more than 10mm by distraction osteogenesis in cleft patients using internal devices. We organised a retrospective study on 42 patients with cleft lip and palate using cephalometric analysis before and after maxillary distraction osteogenesis and evaluated them for 24 months.

A comparison of tooth-borne and bone-anchored expansion devices in SARME.

Oral Maxillofac Surg 2020 Jun 14;24(2):181-187. Epub 2020 Apr 14.

IAMSPE/HSPE, Avenida Ibirapuera 981, Sao Paulo, Sao Paulo, Brazil.

Purpose: Major adult maxillary transverse discrepancies are usually treated with surgically assisted rapid maxillary expansion (SARME), utilizing a combination of surgical and orthodontic techniques. Unfortunately, a consensus has not been reached on topics ranging from the best surgical technique that should be performed to the ideal expander type that should be installed. The present study sought to evaluate the efficiency and stability of the maxillary expansion achieved with two types of expanders following the same SARME procedure without pterygomaxillary disjunction (PMD).

Surgical-Orthodontic Considerations in Subcranial and Frontofacial Distraction.

Oral Maxillofac Surg Clin North Am 2020 May 23;32(2):309-320. Epub 2020 Feb 23.

Craniofacial Center, Divisions of Craniofacial and Plastic Surgery and Oral-Maxillofacial Surgery, Seattle Children's Hospital, 4800 Sand Point Way NE, Seattle, WA 98105, USA. Electronic address:

Subcranial and frontofacial distraction osteogenesis have emerged as powerful tools for management of hypoplasia involving the upper two-thirds of the face. The primary goal of subcranial or frontofacial distraction is to improve the orientation of the upper face and midface structures (frontal bone, orbitozygomatic complex, maxilla, nasal complex) relative to the cranial base, globes, and mandible. The various techniques used are tailored for management of specific phenotypic differences in facial position and may include segmental osteotomies, differential vectors, or synchronous maxillomandibular rotation.

Creation of Bone and Soft Tissue in Postmaxillectomy Patients Using Curvilinear Transport Distraction Osteogenesis.

Ann Maxillofac Surg 2019 Jul-Dec;9(2):319-325

Department of Mechanical Engineering, University of Cape Town, Rondebosch, South Africa.

Background: Large surgical defects in the maxilla due to trauma or tumor are usually reconstructed with revascularized-free fibula flaps (RFFF). In the past, the use of curvilinear transport distraction osteogenesis (CTDO) has been shown to be an efficacious way in closing large defects in the maxilla, but it had limitations which have now been overcome by the present development. The present distractor is an improvement upon the previous three prototypes and employs the concept of tetrafocal distraction by means of hybridizing the bone with the tooth in the transport disc segment.

Acute open callus manipulation: Clinical experience with a new surgical technique for solving old problems in distraction osteogenesis.

J Craniomaxillofac Surg 2019 Feb 7;47(2):219-227. Epub 2018 Dec 7.

Stomatology Department, São José Hospital, R. José António Serrano, Lisbon Portugal.

Background: Transport distraction osteogenesis is challenged as a potential alternative to free-flap reconstruction of segmental jaw defects due to its longer treatment time, vector control difficulties, need for additional bone-grafting, and problems creating a curvilinear shape. We propose a new technique of acute open callus manipulation and fixation (AOCMF), which addresses these challenges.

Methods: A retrospective analysis of all patients with jaw defects who underwent DO and AOCMF between 2006 and 2015 was performed. Read More

Surgery-First Orthognathic Surgery for Severe Facial Asymmetry Combined With Mandibular Distraction Osteogenesis Using a Three-Dimensional Internal Distractor.

J Craniofac Surg 2019 Jan;30(1):39-46

Department of Plastic, Reconstructive and Aesthetic Surgery, Tokyo Metropolitan Police Hospital.

Severe facial asymmetry in adults with hemifacial microsomia or other types of mandibular hypoplasia is challenging to treat with simultaneous maxillomandibular distraction osteogenesis using an external distractor combined with intermaxillary fixation (IMF). Using an external distractor also produces significant distress for patients for at least 8 weeks. Furthermore, mandibular-driven distraction tends to elongate the midface, with difficulty positioning of the center of the maxilla in the center of the face and horizontalization of the occlusal plane.

Intraoral Premaxillary Distraction in a Patient With Maxillary Retrognathic Cleft Lip and Palate: A Case Report.

Cleft Palate Craniofac J 2019 07 19;56(6):827-830. Epub 2018 Nov 19.

1 Department of Oral & Maxillofacial Surgery, Oral Science Research Institute, Yonsei University College of Dentistry, Seoul, South Korea.

Patients with cleft lip and palate sometimes have a retruded maxilla. Here, we describe the case of a young man in whom crowding of the maxillary teeth and an anteroposterior discrepancy of the maxilla were resolved by premaxillary distraction osteogenesis (DO) using 3 individual intraoral distractors. Our experience in this patient confirms that premaxillary DO with 3 intraoral distractors and preoperative simulation can achieve stable maxillary advancement and arch expansion without impairing velopharyngeal incompetence.
