Introduction: As part of surgical interventions in pediatric patients, children with craniofacial malformations and syndromes are presented in the field of oral and maxillofacial surgery, anesthesia and also in all other clinical disciplines. In particular, the Pierre Robin sequence in the clinical context leads to a situation albeit a rare one, which should be given high attention in preoperative, intraoperative and postoperative care.
Material And Methods: In a retrospective analysis from 1993 to 2020 in the Department of Oral and Maxillofacial Surgery at the University Hospital Halle (Saale), a total of 54 patients were identified with syndromic changes and a need for surgical treatment.
The aim of this study is to describe the growth of the upper lip after reconstruction with a Pfeifer wave-line incision in patients with unilateral and bilateral cleft lip and palate (CL/P) in the long term. This was a longitudinal, monocentric, retrospective study. Metric standardized lip length measurements were taken annually from the age of 6 months to the age of 16 years.

Unlike many other congenital malformations facial deformities are visible to all. The uncommon facial appearance creates feelings and reactions in the mother, families and other people.

Gender was not included in statistical analysis at that time. A retrospective analysis of the trial considering gender, preoperative hearing, and nimodipine treatment was performed.

Another purpose was to explore and describe the experience and subjectively perceived reaction of the mother and the social environment to the child before and after cleft lip surgery.
Material And Methods: A study to describe and evaluate mothers' experiences, feelings and emotions (n = 84) regarding having a child with CL/P was performed.
Objectives: This study describes a modified method for secondary correction of whistling deformities in patients with unilateral and bilateral cleft lip/palate (CL/P), using a horizontal double transposition vermilion flap, including parts of the orbicularis oris muscle. The pre- and postoperative results were objectively evaluated.
Study Design: 34 patients with a whistling deformity who underwent secondary reconstruction between 07/2013 and 11/2018 were included in this study (mean age 20.

Clinical and experimental studies show a clear positive effect of B-vitamins in the prevention of oromaxillofacial clefts, especially cleft lip and palate (CL/P). Hereby the local effect of thiamin (B1) in the amniotic fluid is very important for the embryonic facial development as seen in palatal organ models stimulated by topical B-vitamin application (Scheller et al., 2013a).
View Article and Find Full Text PDFPurpose: Cleft lip and palate (CL/P) are one of the most common human birth defects. Animal experiments and clinical investigations show a clear reduction of teratogenic clefts by a high-dose vitamin B supplementation during early pregnancy, especially in families at risk (reduction of recurrence). The aim of this work was to examine the influence of thiamine (vitamin B1) on CL/P appearance in genetically determined A/WySn mice within different supplementation starting points.

Method: A total of 112 patients were recruited for a randomized multi-center trial to investigate the efficacy of prophylactic nimodipine treatment in vestibular schwannoma (VS) surgery. For the present investigation both treatment groups were pooled for the assessment of facial nerve function preoperatively, in the early postoperative course and 1 year after the surgery.
Purpose: Cleft lip and/or palate (CL/P) shows a gender-related distribution in human beings. The reason is unknown. This study analyzed the gender-related cleft appearance with respect to teratogenically and genetically determined cleft appearance and the response to thiamine (vitamin B1) supplementation.

The current problem in its clinical use is sufficient and fast revascularization of the transplanted tissues. The idea of bone-reconstruction deals with three-dimensional bone equivalents that are composed of endothelial cells (ECs) and adipose tissue derived stromal cells (ATSCs) showing osteogenic differentiation.

Objectives: Eagle's syndrome is caused by an elongated or mineralised styloid process and characterised by facial and pharyngeal pain, odynophagia and dysphagia. Diagnosis is based on clinical findings. However radiologic imaging, like panoramic radiograph, helps to confirm the diagnosis.

In addition, the neuroprotective efficacy of nimodipine has been revealed following skull base, laryngeal, and maxillofacial surgery. Pharmacokinetic investigations showed nimodipine to reach higher serum levels following parenteral versus enteral administration.
View Article and Find Full Text PDFPurpose: The pathogenesis and prevention of cleft lip and palate (CL/P) have been studied mainly in clinical and animal experiments. A prophylactic poly-B-vitamin substitution during the first months of pregnancy has provided the most encouraging results for the prevention of CL/P recurrence in families at risk. In vitro studies of the palatal organ in an A/WySn mouse model have confirmed the positive influence of B-vitamins on palatal development.

Unlabelled: BACKGROUND AND STUDY AIMS/OBJECT: Oral nimodipine is recommended to reduce poor outcome related to aneurysmal subarachnoid hemorrhage (SAH). In addition, animal experiments and clinical trails revealed a beneficial effect of enteral and parenteral nimodipine for the regeneration of cranial nerves following skull base, laryngeal, and maxillofacial surgery. Despite these findings there is a lack of pharmacokinetic data in the literature, especially concerning its distribution in nerve tissue.

It belongs to the primary idiopathic osteolysis, and its aetiology is poorly understood. Many different localisations have been described, but there are only 48 cases affecting the maxillofacial region until now.

Adjustable osteosynthesis miniplates are used to facilitate positioning of the mandible after bilateral sagittal split osteotomy (BSSO) to avoid skeletal relapse and occlusal discrepancies. The short Obwegeser BSSO reduces neurosensory disturbances. Adjustable osteosynthesis plates suited for the Obwegeser BSSO are not commercially available.

Because of positive clinical experiences with prophylactic vitamin B substitution in mothers of cleft-related families, the direct influence of the vitamin B-complex on palatal tissue was analyzed.
Materials And Methods: The inbred A/WySnJ mouse strain shows a highly spontaneous, genetically determined clefting rate of 20% to 44%.

The efficacy in terms of persistence of the engineered fat is, however, not yet understood and could depend on the nature of fabrication and application. The high metabolic demand of adipose tissue also points to the problem of vascularization.

Main Observations: An 87-year-old patient with an extended squamous cell carcinoma of the neck was referred to our hospital. The large ulcerated tumour showed a deep infiltration of the para-vertebral muscles and the spinal processes C6-C7.
A case of cervical lymph node infiltration by a benign cellular blue nevus (CBN) and a 27-year disease history is presented. Dermal dendritic melanocytes and pigmented spindle cells presented no histological evidence of malignancy (CD34-, desmin-, PanCy-, HMB-45+, anti-S-100+, Bcl-2+, MART-1+, focally expression of melan A, 1% Ki-67+ of the tumour cell nucleoli). The differentiation of the benign blue nevus (BN) from a malignant blue nevus (MBN) and a malignant melanoma (MM) is still a challenge.
