Use of High-Resolution Ultrasound (HRU) in the Assessment of Deep Injections of CHAP-Hyaluronic Acid (CHAP-HA) Fillers for midface Lift

引用

Journal of Cosmetics, Dermatological Sciences and Applications 2018年第3期8卷 126-132页

High-resolution ultrasound (HRU) imaging is a useful tool to study hyaluronic acid (HA) filler injection in the face. It is noninvasive, quick, well-tolerated, and can provide in vivo and dynamic information. The formations of pools or pearls in HA fillers could be observed real time during injection. The plane of injection could be determined accurately, and there were no specimen manipulation artifacts. It was observed that HA gel fillers with differing production technologies showed distinct spread and distribution patterns in the periocular tissues on HRU examination. The authors used HRU to assess deep injections of CHAP-Hyaluronic Acid (CHAP-HA) fillers for midface lift. 10 patients who underwent bilateral midface deep injections using CHAP-HA filler were examined with HRU before and immediately after treatment, and in 2 weeks and one month later. The CHAP-HA appeared as hypoechoic densities within the preperiosteal plane in HRU. CHAP-HA adopted variable morphology within the tissue depending on individual tissue densities and the compliance of the tissues in the plane of injection. CHAP-HA was unidentifiable with surrounding tissue after one month in 13 of the 20 injection sites. HRU allows in vivo study of CHAP-HA injection behavior and could be a tool for further studies of HA-tissue reactions.

Presentation of multiple midface fractures combined with intracranial injury treated conservatively

引用

Open Journal of Emergency Medicine 2013年第1期1卷 1-3页

midface injuries are normally the result of high forces impacted on the face, that can bypass the power of the connection buttresses, which are thick and strong, base of skull is also a rigid and toughstructure which requires significant forces to break. In our case, multiple midface and cranial base fractures are presented, which reflect injury caused by high forces and normally, these result in instability in the facial skeleton, or cause CSF rhinorrhea, or sharp spicules to endanger the orbit or the anterior cranial fossa, or the presence of any other indication of surgery. It is unusual to find such an extent of facial trauma and such a multiplication of fractures on the midface and cranial base levels, yet they were stable enough and without a real indication to require surgical interference.

Global facial rejuvenation, new technique

引用

Plastic and Aesthetic Research 2018年第7期5卷 20-25页

作者： Giuseppe Colombo Vittorio Ruvolo Koru Day Clinic Center Via Paleocopa 5/3Savona 17100Italy

Facial aging is the combination of multiple effects such as sun exposure, tobacco, environmental stress and smog, reflecting the cumulative and dynamic effects of time on the skin, soft tissues and the deep structural components of the face that show an important change structural features of the skin and loss of facial volume. There are many different techniques currently used to perform face lifting, the ultimate goal is to get good results with respect for patient safety. This article describes a new approach to facial rejuvenation combining superficial musculoaponeurotic system (SMAS) plication elements on four vectors, with a blepharoplasty to achieve a lasting improvement in facial aging. The plication of the SMAS on the suture provides three vectors of elevation under the skin in the middle rhytidectomy, linked to the Lorè fascia and to the third platys elevation vector behind the ear. The blepharoplasty technique is often unavoidable in the execution of the global facial rejuvenation. This allows obtaining excellent results both in terms of aesthetic and of a good patient empowerment. This new surgical technique, called 'KORU technique', was used on 31 patients between October 2010 and October 2012, producing lasting results, reducing injuries and respecting anatomical planes. This approach can be safely and easily performed under local anesthesia as an isolated midface procedure, respecting and safeguarding the facial nerve. This type of chiropractic technique can be used by young surgeons.

A protocol used to manage maxillary hypoplasia in cleft lip and palate patients

引用

Open Journal of Stomatology 2012年第2期2卷 130-135页

作者： Ahmed Alyamani Sondos Abuzinada Oral and Maxillofacial Surgery Department King Abdulaziz University Jeddah Saudi Arabia

Objectives: We report our experience and the protocol we used in managing maxillary hypoplasia in cleft lip and palate patients. Patients and methods: 14 adult cleft lip and palate patients with maxillary hypoplasia were evaluated clinically. Dental models and radiographs including (lateral cephalograms and orthopantographs) were obtained at the initial visit and upon completion of the presurgical orthodontic treatment. Patients with occlusal discrepancies larger than 6 mm and severe palatal scaring underwent Distraction osteogenesis (DO) to advance the maxilla. Patients with an occlusal discrepancy of 6 mm or less, underwent traditional orthognathic surgery including le fort I advancement and Bilateral sagittal split osteotomy (BSSO) to seat the mandible in occlusion. Results: Five patients underwent orthognathic surgery. Two of them underwent double jaw surgery. Three underwent single jaw conventional le fort l advancement. Four patients required bone grafting to repair the residual alveolar defect and to augment the midface deficiency. Nine patients with severe maxillary hypoplasia underwent maxillary advancement using distraction osteogenesis. Conclusion: Patients with a severe maxillary hypoplasia of 6 mm or more and excessive palatal scaring are successfully treated with DO. Conventional le fort I is reserved for patients with less severe maxillary hypoplasia. Both techniques gave promising results providing having followed the proper selection criteria.

Kicked in the Face by a Fish

Open Journal of Emergency Medicine 2015年第4期3卷 41-44页

Facial trauma caused by animals is a well known aetiology for maxillofacial injuries. Our case is an injury to the midface and upper face, caused by an unusual animal in the world of maxillofacial trauma, in circumstances not very commonly seen, and certainly only exists in few parts of the world. This assault results in a fracture in one of the stronger corners of the orbital cavity rather than the commonly seen floor fractures which is partly likely to break first with blunt external trauma.
