Accuracy in orthognathic surgery─comparison of preoperative plan and postoperative outcome using computer-assisted two-dimensional cephalometry by the Onyx Ceph system.

Purpose: This retrospective study analyzes deviations between preoperative planning and postoperative outcome in orthognathic surgery using 2D Onyx Ceph-cephalometric analyzing and planning system.

Materials And Methods: A total of 100 patients with a mean age 25.1 of years were included in this study.

Controlled central advancement of the midface after Le Fort III osteotomy by a 3-point skeletal anchorage.

A 3-point skeletal anchorage with taping screws for distraction osteogenesis after a Le Fort III osteotomy was applied for the first time in a severely mentally impaired patient where intraoral devices had to be avoided. All 3-force application points included the center of resistance, which allowed an optimal control on the resulting moment. A novel device for skeletal long-term retention into the nasal dorsum prevented a relapse, whereas adjustment of the midface position was observed.

Kimura's disease in a white man.

Background: Kimura's disease is a rare inflammatory disease that mainly affects Asians and most often occurs in the deep lymph nodes of the head and neck. We report on a rare case of Kimura's disease in the hard palate of a white man.

Method: A 56-year-old white man was seen with a rapidly growing mass in the upper jaw.

Mandibular prognathism caused by acromegaly - a surgical orthodontic case.

A 22-year-old man presented for orthodontic surgery because of mandibular prognathism. Clinical symptoms suggested acromegaly, and diagnosis was verified by an endocrinologist as well as by radiograph. Bilateral mandibular prognathism often represents the first and most striking physical characteristic of acromegaly; usually, it is also the main reason why patients seek help from orthodontists or maxillo-facial surgeons.

Intralesional corticosteroid therapy for mandibular Langerhans cell histiocytosis preserving the intralesional tooth germ.

Background: Langerhans cell histiocytosis (LCH, histiocytosis X, ICD-O 9751/1) refers to a neoplastic proliferation of Langerhans cells. The course of the disease determines the treatment and prognosis. Solitary forms (eosinophilic granuloma) and limited multilocational lesions may be treated successfully with local surgical intervention and intralesional corticosteroid injection.

[Identification of a recurrent oral squamous cell carcinoma by brush cytology].

Background: Large oral lesions comprise the risk that an incisional biopsy does not reveal the most aggressive site in spite of carefully selecting the place of biopsy.

Case Report: The first incisional biopsy of a large, clinically suspect, oral lesion could not identify the subepidermal spread of a recurrent oral squamous cell carcinoma. Atypical cells obtained by a simultaneous brush biopsy prompted a renewed, incisional biopsy which finally established the diagnosis of a recurrent, oral squamous cell carcinoma.
