Five years experience with a new intraoral maxillary distraction device (RID)

10 Distraction Osteogenesis

“…In 19 syndromic, cleft, and traumatic patients treated with this distractor, an average advancement of 9.6 mm was achieved. [54] A retrospective study comparing extraoral and intraoral distractors for midface advancement in syndromic patients demonstrated no significant difference regarding the complication rate and amount of lengthening between the two types. Accordingly, both distractors were asserted to be safe and it was suggested that choosing a device be individualized based on each patients needs and toleration.…”

“…Moreover, being more easily tolerated by patients, an internal device can be maintained during the consolidation phase for as long as deemed necessary for prevention of relapse. [53], [54], [56] Nevertheless, installation of intraoral distractors may not be always feasible due to inadequate space. In addition, intraoral distractors provide unidirectional bone movement; hence demanding precise positioning.…”

“…[53] Yet, many patients have difficulty accepting extraoral devices primarily due to the unappealing appearance and discomfort. [54] Moreover, the external position of these devices makes them prone to loosening and fracture following an accidental trauma. [53] Rigid external distraction (RED) device is fixed to the cranium.…”

“…This allows for protection of maxillary teeth comparing to other types of extraoral devices which are anchored to the maxilla. [54] The stability of maxillary advancement with RED was evaluated in a 3-year prospective study. To avoid the possible interference of growth in the outcomes, the study was performed on adult patients.…”

Interventional calendar and protocol for cleft lift and palate repair at the maxillofacial and plastic surgery department of the Armand Trousseau Children’s Hospital (AP-HP, Paris)

“…We perform intermediate surgery of maxillary distraction with a technique most of whose components we developed at our Center using a hybrid, internal distractor with double bone and dental anchorage 2,3 . Indications for distraction therapy most often arise for patients with syndromic clefts not accompanied by a short, hypoplastic lip.…”
