Ten years have passed since publication of the first atlas by the same editors. In that edition, the primary focus was on the use of small plates and screws in craniomaxillofacial surgery. Since then, there have been many advances in materials, plate and screw designs, surgical equipment, and techniques. In this second edition, the editors have sought input from a host of widely respected international surgeons to update the previous edition and provide the latest information in craniomaxillofacial fixation techniques.

Lateral orbitotomy: a useful technique in the management of severe traumatic disruption of the lateral orbital skeletonEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Abstract: Lateral orbitotomy is a well-recognized method of improving orbital access for the removal of orbital tumours and foreign bodies, and has been used in orbital decompression in dysthyroid eye disease. The technique has received less attention in the management of orbital trauma. Lateral orbitotomy is useful in the management of selected cases of orbital trauma, in particular severe disruption of the lateral orbit requiring extensive dissection in the region of the superior orbital fissure. It is used in patients with globe rupture, with lateral orbital disruption, in helping to reduce the amount of globe retractio...

Selection of optimal dental implant diameter and length in type IV bone: a three-dimensional finite element analysisEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
This study aimed to create a 3D finite element model for continuous variation of implant diameter and length, thereby identifying their optimal range in type IV bone under biomechanical consideration. Implant diameter ranged from 3.0 to 5.0mm, and implant length ranged from 6.0 to 14.0mm. The results suggest that under axial load, the maximum Von Mises stresses in cortical and cancellous bones decrease by 50% and 27%, respectively; and under buccolingual load, by 52% and 60%, respectively. Under these two loads, the maximum displacements of implant-abutment complex decrease by 39% and 43%, respectively. These results indic...

Chin shield osteotomy – a new genioplasty technique avoiding a deep mento-labial fold in order to increase the labial competenceEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Abstract: The authors report a genioplasty technique in which the advancement of an anterior mandibular segment is executed with a specific osteotomy form that helps to avoid a deep mentolabial fold and improves labial competence. The osteotomy presented achieves this by creating a ‘chin shield’ where the mandibular segment advanced is relatively high on the side of the buccal cortex and lower on the lingual side and where the osteotomy or down-fracture in between is in an oblique angle in the sagittal plane.

The aim of this study was to determine the effects of orthognathic surgery on the auditory status of patients. 54 consecutive patients who met the inclusion criteria underwent audiometric tests 24h preoperatively, and 48h 6 weeks and 8 weeks postoperatively (2 weeks after maxillomandibular fixation removal). Surgery was on the maxilla, mandible or both. The types of movements were recorded. Audiometric examinations include...

Bone grafting and insertion of dental implants followed by Le Fort advancement for correction of severely atrophic maxilla in young patientsEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Abstract: The atrophic maxilla often results in lateral, anteroposterior and vertical disproportion of the maxillary arches. This paper presents the case of a 40-year-old male with a severely atrophic maxilla who underwent oral rehabilitation. He was treated with onlay and inlay iliac bone grafts followed by vestibuloplasty and dental implant placement 170 days after initial bone grafting. The dental implants were uncovered after 4 months of healing. The patient also underwent orthognathic surgery for correction of the maxillary basal bone and to improve implant positioning. At the 48-month follow-up there were no complica...

Navigation-guided gap arthroplasty in the treatment of temporomandibular joint ankylosisEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
This study evaluated the application of image-guided navigation to gap arthroplasty. Four gap arthroplasties were performed on patients with unilateral TMJ ankylosis under computer-assisted navigation guidance. After preoperative planning and 3-dimensional simulation, the normal anatomic structures of the TMJ were created by superimposing and comparing the unaffected and affected sides. The amount and range of ankylotic bone to be resected was determined and displayed. Registration achieved an accurate match between the intra-operative anatomy and the CT virtual images. Anatomic structures and the position of surgical inst...

Use of nasal packs and intranasal septal splints following septoplastyEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Abstract: The aim of this study was to compare the efficacy of a trans-septum suturing technique with conventional nasal packing and intranasal splints in the classic septoplasty operation. The study is a prospective, randomized clinical trial. 114 patients underwent septoplasty for septal deviation and ensuing nasal obstruction. These patients were divided into two groups: packing (using intranasal septal splints and antibiotic meshes at the end of the operation) and non-packing (using four separate trans-septum through and through horizontal mattress sutures without any mesh or intranasal splint insertion). Randomization...

Intraosseous ‘haemangioma’ of the zygoma: More appropriately termed a venous malformationEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Abstract: Vascular anomalies often affect the soft tissues and primary intraosseous lesions are uncommon, with only 33 cases reported in the zygoma. Intraosseous vascular anomalies of the zygoma have traditionally been designated ‘haemangiomas’ with little attempt to clarify the specific type of the lesion. Recently, specific immunohistochemical markers such as erythrocyte type glucose transporter protein 1 (GLUT-1) have been described to differentiate haemangiomas and vascular malformations. The authors report a case of intraosseous venous malformation of the zygoma and provide supporting evidence to justify the nomen...

The impact of Le Fort I advancement and bilateral sagittal split osteotomy setback on ventilation during sleepEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Abstract: The impact of orthognathic surgery for class III malocclusion on ventilation during sleep was examined using a comparison of pre- and post-surgical respiratory parameters. 21 patients with both maxillary hypoplasia and mandibular excess underwent Le Fort I osteotomy and advancement together with bilateral sagittal split osteotomy (BSSO) setback. Respiratory parameters, ECG and position of the body were monitored before surgery and postoperatively after the fixation removal (mean 8.5 months). Average Le Fort I advancement was 4.44mm, BSSO setback was 4.96mm. Generally, the orthognathic procedure worsened breathing...

Mechanical anisotropy of orthodontic mini-implantsEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
This study investigated stress distribution in the bone around orthodontic mini-implants using the finite element method and determined the difference in the stress distribution for different loading directions to identify risk factors for the loosening of mini-implants. Three-dimensional finite element models were constructed for conventional and cervical threadless mini-implants with cortical bone 1 or 3mm thick. The authors calculated the compressive stresses on the bone elements and evaluated stress distribution according to the loading direction. Directional dependency (i.e. mechanical anisotropy) was observed with th...

Modification of surgical technique in isolated zygomatic arch fracture repair: seven case studiesEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Abstract: Closed reduction is applied in most cases of isolated zygomatic arch fracture. Open reduction and internal rigid fixation through a coronal incision have to be performed in other comminuted arch fractures. The authors introduced an endoscopic-assisted approach via a small preauricular incision to achieve reposition and osteosynthesis of isolated zygomatic arch fractures. The endoscopic-assisted surgical technique was performed in 7 patients with unilateral isolated zygomatic arch fractures. Endoscopically controlled management of the isolated zygomatic arch fracture was feasible in all 7 patients. The follow-up p...

Isthmus retraction hook for open tracheostomy: Technical noteEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Abstract: Elective conventional open tracheostomy is routinely performed by dividing the isthmus of the thyroid gland. An isthmus retraction hook is introduced that allows the isthmus to be preserved during open tracheostomy by retracting the isthmus cranially or caudally of the chosen tracheostomy site. The hook has been used in over 350 planned open tracheostomies; the isthmus was preserved in all cases. (Source: International Journal of Oral and Maxillofacial Surgery)

Gingival metastasis of ovarian carcinoma: report of a case and review of the literatureEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Abstract: Diagnosing gingival metastases is difficult because clinically they can mimic benign oral lesions. The authors report an unusual case of metastatic ovarian carcinoma in the gingiva of a 46-year-old woman 5 years after ovariectomy. The tumor presented as an exophytic growth at the molar region of the mandible. Histological examination showed invasive proliferation of atypical glandular structures composed of mucin-producing cells laying in a fibrous stroma. Tumor cells were immunopositive for carcinoembryonic antigen, MUC1 mucin, and lysozyme, while stromal fibroblasts were immunopositive for vimentin and estrogen...
