BACKGROUND: In longstanding facial palsy, gracilis free functional muscle transfer (FFMT) is currently considered to be the gold standard in smile reanimation. An alternative to muscle free flaps is local muscle transposition, with the temporalis muscle transposition being the preferred procedure, because of its direction of pull when transposed. The present study aimed to compare outcomes of gracilis FFMT neurotised by the masseteric nerve and temporalis muscle transposition in longstanding facial palsy using patient-reported and aesthetic outcomes...

INTRODUCTION: Besides mastoid air filled cells, pneumatizations (PN) occasionally occur in the articular eminence (AE) of the temporomandibular joint (TMJ). These findings represent no pathological character but may increase the risk of perforating the AE during eminectomy with potential harming the skull base. Various classifications catagorize the degree of temporal PN without focussing solely on the AE. Panoramic radiograph (PR) and computed tomographie (CT) are both described as suitable for diagnosing PNs...

BACKGROUND: Quality of life in tumour patients following combined ablative and reconstructive head and neck surgery varies significantly. This is at least partially due to differences in speech and swallowing function. A tool to objectively evaluate articulation by magnetic resonance imaging (MRI) has now been tested alongside ultrasound examination. PATIENTS AND METHODS: A standardized sequence of phonemes from the German language was established in 20 healthy volunteers and recorded in different planes by MRI and ultrasound...

2,3,7,8-Tetrachlorodibenzo-p-dioxin (TCDD) induces cleft palate and hydronephrosis in the mouse embryo. Cleft palate occurs due to failure in palatal grow, but the underlying mechanisms are unclear. We investigated the mechanisms of cleft palate development in TCDD-exposed mouse embryos. We administered olive oil (control group) or TCDD diluted in olive oil (40 μg/kg) via gastric tubes to pregnant mice on gestational day (GD) 12. Embryos of control and TCDD-exposed groups were removed from pregnant mice on GD 14 and GD 15, respectively...

Bilateral sagittal split ramus osteotomy (BSSO) surgery is used to correct various dento-skeletal deformities. Clinical outcomes are critically dependent on accurate and proper positioning of skeletal units created by BSSO. Monitoring skeletal changes postoperatively is a major part of follow-up. Between January 2015 and December 2015, 24 patients underwent BSSO surgery without any other segmental osteotomy (mean age, 29.9 ± 14.2 [range, 17-67] years; 18 females). Cephalometric X-rays and cone-beam computed tomography scans were performed 6 weeks and 12 months postoperatively...

PURPOSE: The fibula flap has been established for orofacial reconstruction following ablative surgery. Donor-site morbidity of the lower leg may be explained by the harvest technique and particularly by detachment of the M. extensor halluces longus (EHL) and M. extensor digitorum longus (EDL). MATERIAL AND METHODS: On cadaveric lower leg specimens, the tendons of the EHL and EDL were dissected at the proximal phalanges and loaded with corresponding weights. The average displacement of the muscle was evaluated during the harvesting procedure...

Platelet-rich plasma (PRP) with normal and below-normal physiological concentrations of platelets is designated as diluted PRP (dPRP). The aims of this study are to evaluate whether bone mineral matrix in combination with dPRP possesses osteogenic capacity; and whether the differences in dynamics and osteogenic process pattern depend on different platelet concentrations, to what extent, and also what could be benefits for bone regeneration in clinical practice. Three types of implants were made: BMM-bone mineral matrix alone; dPRP/10-bone mineral matrix mixed with dPRP (concentration of platelets 10 times lower than physiological level) and dPRP/3-bone mineral matrix mixed with dPRP (concentration of platelets 3 times lower than physiological level)...
