Maxillomandibular advancement as the initial treatment of obstructive sleep apnoea: Is the mandibular occlusal plane the key?

Maxillomandibular advancement (MMA) can be effective for managing obstructive sleep apnoea (OSA); however, limited information is available on the predictor surgical variables. This study investigated whether normalization of the mandibular occlusal plane (MOP) was a determinant factor in curing OSA. Patients with moderate or severe OSA who underwent MMA were evaluated by preoperative and postoperative three-dimensional (3D) scans and polysomnograms.

Pedicled buccal fat pad flap for upper lip augmentation in orthognathic surgery patients.

Purpose: In this article, a new method of upper lip augmentation using a bilateral buccal fat pad flap is reported. This prospective study evaluated the changes in the upper lip that occur after maxillary surgery with concomitant mobilization of the bilateral buccal fat to improve upper lip projection.

Materials And Methods: A bilateral pedicled buccal fat pad flap to fill the premaxilla, paranasal, and upper lip areas, in association with a Le Fort I osteotomy for maxillary advancement, was performed in 11 orthognathic surgical patients with a thin upper lip.

5-year clinical experience with BTI dental implants: risk factors for implant failure.

Objectives: The aims of this study were to identify with appropriate statistical tests the risk factors associated with implant failure and to evaluate the long-term survival of dental implants using implant loss as an outcome variable and performing an implant-, surgery- and patient-based analysis of failures.

Material And Methods: A retrospective cohort study design was used. One thousand sixty patients received 5787 BTI implants during the years of 2001-2005 in Vitoria, Spain.

Autologous platelets as a source of proteins for healing and tissue regeneration.

Platelets are known for their role in haemostasis where they help prevent blood loss at sites of vascular injury. To do this, they adhere, aggregate and form a procoagulant surface leading to thrombin generation and fibrin formation. Platelets also release substances that promote tissue repair and influence the reactivity of vascular and other blood cells in angiogenesis and inflammation.

[The value of a previously expanded musculo-cutaneous flap of the lower eyelid for the reconstruction of a full thickness loss of tissue substance of the upper eyelid].

The authors report a new technique for the reconstruction of upper eyelid full thickness tissue losses in preserving the inferior edge. They describe a myo-cutaneous inferior eyelid flap which has been preliminarily expanded before transposition. An anatomical study has demonstrated vascularization and innervation of the myo-cutaneous eyelid flap which will remain active.
