N J Burton, L Meakin, A Hosworth, K J Parsons
OBJECTIVES: To evaluate the reliability of CT measurement of canine elbow axial radioulnar congruence using a duplicated circle superimposition technique. MATERIALS AND METHODS: CT of six cadaveric canine elbows was performed following either: (1) placement of an external fixator on the radius with ostectomy and radial shortening of 1 to 5 mm; (2) radial lengthening of 1 to 5 mm using a radial lengthening system; or, (3) no axial length adjustment. Four observers, on two occasions, blinded to the amount of radial adjustment, placed a circle of best fit of the ulnar trochlear notch on a sagittal image that was duplicated and transposed to the articular contour of the radial head; then the axial distance between circles relative to the dorsal radius was measured...

Bilateral masseter muscle hypertrophy is an alteration in shape and thickness of the masseter muscles that can modify the width of the lower face causing aesthetic and functional problems. A 21-year-old man was referred to the Department of Maxillofacial Surgery at the Civil Hospital in Brescia by his dentist for an evaluation of his facial appearance with a square-face type. To reduce the undesirable facial appearance, a surgical intraoral approach was performed; the procedure includes the bilateral dissection of the masseter muscle, partial lipectomy, and the ostectomy of the mandibular angle assisted by a surgical guide built on a stereolithographic model...

Deformities of the cranium in patients with nonsyndromic single-suture synostosis occur because of growth restriction at fused sutures and growth over compensation at normal sutures. Traditional surgery includes ostectomies of the synostotic suture to release these restricted areas and osteotomies to enable immediate cranial remodeling. In the process of reshaping the cranium, traditional approaches usually involve obliteration of both the normal functioning suture and the pathologic suture. The directive growth approach (DGA) is a new, simpler, more natural way to repair deformities caused by single-suture cranial synostosis...

OBJECTIVE To evaluate the efficacy of castor oil polyurethane polymer with calcium carbonate for use in a unicortical ostectomy on the dorsal surface of the third metacarpal bone of horses. ANIMALS 6 adult horses. PROCEDURES A unicortical ostectomy was created on the dorsal surface of both third metacarpal bones of each horse. Castor bean (Ricinus communis) oil polyurethane polymer with calcium carbonate was implanted into the ostectomy on 1 limb, and the ostectomy of the contralateral limb was left unfilled and served as a control sample...

OBJECTIVE: To assess the influence of a 50% distal ulnectomy on mediolateral carpal stability in the dog. STUDY DESIGN: Canine cadaveric study. SAMPLE POPULATION: Seven canine thoracic limbs METHODS: Thoracic limbs were placed in a jig to mimic weight bearing with a load representing 30% of body weight. Carpal extension angle was standardized at 190° ± 5°. Frontal plane carpal angles were measured with the limb loaded on craniocaudal radiographs before and after ulnectomy...

The aim of this case series study was to illustrate the bone lid technique implemented using piezoelectric surgery to access mandibular alveolar bone diseases and to assess the clinical and radiographic outcomes. The technique was used to treat 21 consecutive patients with various conditions: cysts in six cases, impacted teeth with associated cysts in nine, keratocystic odontogenic tumours in three, impacted teeth in two, and an endodontic lesion in one. The bone lid was fashioned using piezoelectric surgery and a thin osteotomy insert...

PURPOSE: The aim of this study was to assess the effect of local application of growth hormone on osseointegration of dental implants inserted in osteoporotic bones. MATERIALS AND METHODS: Twenty female New Zealand rabbits were used in this study. Ten were ovariectomized and fed a low-calcium diet for 6 weeks, and the others remained intact. A titanium implant was inserted into each tibia, in both groups. In half of the rabbits, 2 IU of growth hormone was placed into the ostectomy prior to the implant insertion...

Multiple keratocystic odontogenic tumors (KCOT) occurred in a young child is challenging problem in the field of pediatric dentistry, and might have been related to nevoid basal cell carcinoma syndrome (NBCCS). Because of high recurrence rate of KCOTs, complete surgical resection is generally accepted as definitive treatment. However, complete surgical resection could induce negative effect on the development of permanent teeth and growth of jaw. Herein, we reported successful treatment case of young KCOT patient with NBCCS...

BACKGROUND: Because of the limitation of specific preoperative design and surgical templates, orthognathic surgery and mandibular contour osteoplasty are generally performed in two stages. Three-dimensional printing technology has improved the accuracy of the surgery and results in good surgical predictability easily. This study aims to confirm the effectiveness, feasibility and precision of simultaneous mandibular contour osteoplasty and orthognathic surgery with the assistance of 3D printing technology...

This article reports on a case of a glandular odontogenic cyst (GOC) in the posterior mandible of a 25-year-old male treated with peripheral ostectomy, bone allograft, and an implant-supported fixed dental prosthesis. During a routine 3-month postoperative visit, a radiograph suggested vertical bone loss on the implant in the location of the mandibular right first molar. The three-walled defect was surgically treated with debridement, bone allograft, and a membrane. Healing of this site has been uneventful...

Hemimandibular hyperplasia is a rare type of condylar hyperplasia which leads to facial asymmetry. Its surgical correction may be challenging since it usually requires complex mandibular osteotomies. Mandibular inferior border ostectomy is poorly described in the literature. The aim of this report is to present a new surgical technique guided by a customized surgical splint manufactured using computer-aided design/computer-aided manufacturing technology. Very good aesthetic results are achieved as it is very precise...

Various forms of vascular lesion affect the head and neck region. The head and neck vascular lesions are classified into neoplasms and malformations. Neoplasm presents either as hemangioma or lymphangioma; neoplasm usually presents in young age compared with vascular malformation. A 9-year-old female patient presented to the outpatient clinic referred from the department of pedodontics after extraction of a right mandibular second deciduous molar. Extraction was done by dental GP in outpatient clinic. Massive bleeding followed the extraction...

BACKGROUND: Temporohyoid osteoarthropathy (THO) is a cause of neurological disease in horses that is characterised by facial and vestibulocochlear nerve deficits. Studies reporting and comparing survival following medical or surgical treatment of THO are lacking. OBJECTIVES: To compare survival and prognosis in horses with THO treated medically or surgically, and to report surgical complications. STUDY DESIGN: Retrospective study. METHODS: The medical records of horses diagnosed with THO were retrieved, and data on signalment, clinical signs and duration, corneal ulceration and bilateral occurrence were recorded...
