Osteomyelitis of the mandible following third molar surgery: a regrettable consequence in a healthy patient.

This clinical case describes mandibular osteomyelitis in a healthy 31-year-old man as a severe complication following third molar removal. Recurrent abscess formations were treated with intensive therapy involving antibiotics, surgical debridement of the affected region, and hyperbaric oxygen. In the follow-up, despite microbiologic study to determine the indicated treatment approach, a severe osteomyelitis was present, clinically and radiographically.

Speech and swallowing impairment after treatment for oral and oropharyngeal cancer.

Objectives: To assess the prevalence of speech and swallowing impairment after radical surgery for oral and oropharyngeal cancer from the patient's viewpoint and to examine the association of these functional alterations with selected clinical characteristics regarding patients, tumors, and oncologic treatment.

Design: Cross-sectional, multicenter study using a self-administered questionnaire.

Setting: Forty-three hospitals in Germany, Switzerland, and Austria.

Diplopia and acute rectus muscle palsy as symptoms of an infected follicular cyst of a maxillary right third molar: a case report.

Severely impacted third molars have a high risk of developing a dentigerous cyst. Dental cysts in the maxilla can cause acute infection of the maxillary sinus that can involve the orbital cavity. Possible complications of infections of the orbital cavity are eyesight reduction, including blindness, and disseminated infections, including brain abscesses.

Zygoma implant-supported prosthetic rehabilitation after partial maxillectomy using surgical navigation: a clinical report.

The rehabilitation of patients with acquired defects of the maxilla is a challenge in terms of reestablishing oronasal separation. In most patients these goals are met by means of prosthetic rehabilitation with an obturator prosthesis. If the remaining dentition does not offer sufficient retention and support, the placement of zygoma implants can enhance the stability of the prosthesis.

Alveolar zygomatic buttress: A new donor site for limited preimplant augmentation procedures.

Purpose: Augmentation of anterior maxillary alveolar bone defects before placement of endosseous implants still poses a clinical challenge. Previous traumatic loss of upper anterior teeth is often concomitant with significant bone loss. The aim of augmentation is to reconstitute as far as possible the original hard tissue contour.

Bone formation after sinus augmentation with engineered bone.

Objectives: The aim of the following investigation was to quantify the resorption rate of tissue-engineered bone grafts in the maxillary sinus using volume measurements.

Material And Methods: Sinus floor augmentation using autologous bone grafts from the iliac crest (n=17, group 1) was compared with commercially produced transplants of human cells seeded on polyglycolid-polylactid (PLGA) scaffolds (Oral Bone) (n=14, group 2).

Results: The total resorption rate for autologous transplants 3 months post operation was 29%, while the tissue-engineered bone showed a resorption rate of 90%.

Complicated late mandibular fracture following third molar removal.

Mandibular fractures are a rare complication after third molar removal. Symptoms show a wide variance. Treatment options range from prescription of a soft diet to surgical treatment by open reduction and internal fixation.

Obturator after marsupialization of a recurrence of a radicular cyst of the mandible.

The radicular cyst is the most common odontogenic cyst. We present the case of a 51-year-old man with an extended recurrence of a radicular cyst of the mandible that was treated with marsupialization. Subsequently, an obturator was fitted, and in 10 months a resolution (clinically and radiographically) of the cystic cavity was noticed without any signs of recurrence.

Orbital abscess after extraction of a maxillary wisdom tooth.

A 21-year-old patient with orbital abscess and vision loss left after wisdom-tooth extraction is presented.

Computer-assisted reconstruction of orbital floor based on cone beam tomography.

We used a navigation system for computer-assisted preoperative planning based on cone beam tomography with virtual reconstruction to obtain symmetry of the orbit and intraoperative control of virtual contours. In operations for reconstruction of the orbital floor this technique offers a reliable intraoperative control in an area of limited exposure and visibility. There was no significant difference in visualisation of anatomical structures between the cone beam tomographic digital imaging and communication (DICOM) data and computed tomographic data.

Minimally invasive open reduction of a displaced condylar fracture in a child.

We treated successfully a severely displaced condylar fracture in a child 9 years of age by endoscopically assisted open operation.

Navigation-aided reconstruction of medial orbital wall and floor contour in cranio-maxillofacial reconstruction.

The reconstruction of the anterio-posterior inclination of the medial aspect of the orbital floor, despite a wide 360 degrees exposure, including coronal and conjunctival incisions, is a challenging task in severe injuries of the orbit with massive comminution and complete displacement of the medial orbital wall and orbital floor. Out of a total of 20 patients with orbital fractures, five underwent a surgical intervention of repositioning the medial aspect of the orbital floor and especially the transition area between the orbital floor and medial orbital wall, using navigation-aided procedures. Using the mirroring tool of the Stryker-Leibinger STN-system, post-operative CTs indicated an average difference of the globe position of -4.
