Motivation for orthognathic treatment and anticipated satisfaction levels - a two-centre cross-national audit

PURPOSE: This audit investigated factors which motivate patients to seek orthognathic treatment, assessed how confident patients were that they would be satisfied with the outcome of treatment, and explored possible influencing factors. MATERIALS AND METHODS: Questionnaires were distributed to pre-surgical patients at two centres (United Kingdom and Switzerland); questions asked what patients wished to gain from orthognathic treatment and how confident they were that they would be satisfied with treatment outcome. Gender, age and location were recorded as demographic variables, and type of malocclusion was also recorded. RESULTS: A total of 202 questionnaires were returned (UK, n=149; Switzerland, n=53). Reported motivating factors focused on improvements in aesthetics (specified and unspecified) (UK vs. Switzerland: 91.3% vs. 83.0%), function (72.5% vs. 66.0%), psychosocial health (51.7% vs. 20.8%), speech (4.0% vs. 7.5%), alleviation of pain (5.4% vs. 17%) and normalization of breathing (1.3% vs. 7.5%). No significant relationships were observed relative to patient age, gender or malocclusion. The anticipated satisfaction levels were generally high (86.5% vs. 89.9%). CONCLUSION: Although the distribution of motivational factors varied between the two sites, it did not affect the anticipated satisfaction level. Patients were generally confident that they would be satisfied with their treatment outcome and that their reasons for seeking treatment would be addressed

The galea fascia flap in orbital reconstruction: Innovative harvest technique

Aim: To report the treatment of a recurrent adenoid-cystic carcinoma of the lacrimal gland required orbital exenteration with an en bloc resection of the lateral orbital rim and wall and an anterior portion of the temporal muscle. Reconstruction was planned with both the objectives of a shortened healing time for faster epithetic reconstruction and no visible scars. Method: After a cranially extended temporal approach, the dissection of the superficial galea layer was connected with the subcutaneous dissection of the upper and lower eyelid after subciliary incisions. Results: Ample exposure of the temporal, frontal and orbital region was obtained, facilitating the orbital exenteration with en bloc resection of the lateral orbital rim and wall and the anterior portion of the temporal muscle. The epithelialization of the eye socket covered with the galea fascia flap was accelerated, providing faster epithetic reconstruction, without visible scars. Conclusions: Healing time is accelerated, providing faster epithetic rehabilitation without visible scars, which is important in the postoperative rehabilitation ladder after eye exenteration for both patient and surgeon. Further more ablative surgery within this region gets safer and easier due to the ample exposure of this innovated surgical technique. Further evaluation of the effectiveness and safety of this new approach is advisable. © 2006 Elsevier Ltd. All rights reserved.link_to_subscribed_fulltex

Therapy of recurrent fixed anterior TMJ dislocation with mini-plates in an aged patient with other ailments. A case report | Die Therapie der rezidivierenden, fixierten anterioren Kieferluxation mittels einer T-förmigen Miniplatte bei einer älteren polymorbiden Patientin--ein Fallbericht]

Unilateral or bilateral dislocation of the TMJ is frequent. Usually it can be treated by the method described by Hippocrates. If conservative treatment (splint therapy, biofeedback, etc.) does not succeed related to recurrent fixed TMJ-dislocation, surgical therapy strategies become necessary. Above all mentally retarded or patients with neuromuscular disorders may necessitate surgical treatment. The two surgical main procedures are: 1. Removal of mechanical obstacles by reduction of the eminentia. 2. Creation of a mechanical obstacle towards the anterior condylar translation. The here presented case shows the treatment of a reccurent, fixed anterior TMJ-dislocation using a miniplate which enables a absolut heightening of the articular tubercle in a 76 years old lady with Morbus Alzheimer and Parkinson. Due to the high incidence of plate fractures, this well discribed therapy, known as miniplate eminoplasty, can not be considered as the treatment of choice for mandibular dislocation. It can be indicated in non-compliant patients or in patients with neuromuscular disorders or in the combination of both as in our case.link_to_subscribed_fulltex

Assessing aesthetic outcomes after trigonocephaly correction

PURPOSE: This study analysed the aesthetic outcome assessments after trigonocephaly correction using different assessor groups. METHODS: Twenty-four patients (9 males, 15 females) with a surgical age between 8 and 10 months were included. Standardised photographs showing different facial views of the patients between ages 3 and 6 years were evaluated in terms of aesthetics by three study groups: surgeons, medical students, and lay persons. Each photograph was scored as follows: 1 (normal), 2 (acceptable, no need for revision), or 3 (unacceptable, needs revision). RESULTS: The mean surgical age was 9.1 ±0.4 months. Based on the en-face images, the mean scores assigned by the surgeon, student, and lay groups were 1.4 ±0.49, 1.25 ±0.44, and 1.13 ±0.34, respectively. Based on the patients' profiles, the mean scores assigned by the surgeon, student, and lay groups were 1.37 ±0.49, 1.16 ±0.37, and 1.09 ±0.29, respectively. The scores of the hemi-profile evaluation were 1.14 ±0.35, 1.07 ±0.26, and 1.09 ±0.31, respectively. The scores of the frontal region were 1.47 ±0.54, 1.33 ±0.49, and 1.39 ±0.49, respectively. Within the orbital area, the surgeon, student, and lay groups assigned mean scores of 1.53 ±0.56, 1.29 ±0.46, and 1.15 ±0.36, respectively. The midface analysis showed mean scores of 1.8 ±0.66, 1.63 ±0.52, and 1.46 ±0.5, respectively. In all areas, there were significant differences (P < 0.05) among the assessor groups. CONCLUSION: The expectations regarding aesthetic outcome differ considerably between experts and non-experts. The need for correction did not concern the reshaped bone but rather the soft tissue epicanthal area

Estimulação cerebral contínua (DBS) talâmica para controle do tremor Deep brain stimulation of VIM thalamic nucleus for tremor control

OBJETIVO: Apresentamos resultados da estimulação contínua do núcleo ventral intermédio (VIM) talâmico para o controle do tremor. MÉTODO: Quatro pacientes foram selecionados no período de outubro de 1999 a janeiro de 2001 com tremor incapacitante refratário à farmacoterapia. Dois pacientes apresentavam tremor essencial (TE) bilateral e 2 pacientes tremor de repouso por doença de Parkinson (DP), um à direita e outro à esquerda. Após avaliação sistemática, foram submetidos ao implante de eletrodo talâmico, modelo DBS 3387(Medtronic), para estimulação cerebral profunda (ECP) com alta frequência, sendo este bilateral nos casos de TE e unilateral nos casos com tremor por DP. RESULTADOS: Os pacientes tiveram seu seguimente clínico até o presente, com média de 12 meses, sendo observada a eficácia da estimulação do núcleo VIM no controle dos disparos das células do tremor. As complicações temporárias do tipo parestesias, disartrias e discreto aumento do tônus foram revertidas após o ajuste dos parâmetros de estimulação. CONCLUSÃO: Os resultados confirmam os achados da literatura, de que a estimulação talâmica é excelente opção terapêutica no tratamento do tremor, havendo possibilidade de estimulação talâmica bilateral simultânea com segurança.<br>PURPOSE: We present our results in 4 patients with tremor, in whom electrodes (uni and bilateral) for Deep Brain Stimulation (DBS) were implanted in the ventral intermediate nucleus (VIM) of the thalamus. METHOD: Four patients with disabling tremor, with drug-resistant spite of optimum therapeutic trials with poor response were referred to do surgery. Two patients had bilateral essential tremor. These patients were implanted with electrodes for DBS 3387 (Medtronic). Two patients had unilateral parkinsonian tremor and they received unilateral implantation of model 3387 DBS. RESULTS: All four patients showed relieve of the tremor symptoms with significant tremor control seen at the scores. There were no definite adverse events after the electrodes implants for DBS; adverse events were transient and promptly reversed after the adjustment of the parameters. CONCLUSIONS: The results the authors found in this study indicate that VIM-stimulation is effective for tremor control either parkinsonian or essential tremor. The results correlate with the data in the literature

Validity of the 3D VECTRA photogrammetric surface imaging system for cranio-maxillofacial anthropometric measurements

PURPOSE: The use of three-dimensional (3D) photography for anthropometric measurements is of increasing interest, especially in the cranio-maxillofacial field. Before standard implementation, accurate determination of the precision and accuracy of each system is mandatory. METHODS: A mannequin head was labelled with 52 landmarks, and 28 three-dimensional images were taken using a commercially available five-pod 3D photosystem (3D VECTRA; Canfield, Fairfield, NJ) in different head positions. Distances between the landmarks were measured manually using a conventional calliper and compared with the digitally calculated distances acquired from labelling by two independent observers. The experimental set-up accounted for clinical circumstances by varying the positioning (vertical, horizontal, sagittal) of the phantom. RESULTS: In the entire calliper measurement data set (n = 410), a significant difference (p = 0.02) between the directly measured and corresponding virtually calculated distances was found. The mean aberration between both modalities covering all data was 7.96 mm. No differences (p = 0.94) between the two groups were found using a cut-off of 10 % (leaving n = 369 distances) due to considerable errors in direct measurements and the necessary manual data translation. The mean diversity of both measurement modalities after cut-off was 1.33 mm (maximum, 6.70 mm). Inter-observer analysis of all 1,326 distances showed no difference (p = 0.99; maximal difference, 0.58 mm) in the digital measurements. CONCLUSION: The precision and accuracy of this five-pod 3D photosystem suggests its suitability for clinical applications, particularly anthropometric studies. Three-hundred-and-sixty degree surface-contour mapping of the craniofacial region within milliseconds is particularly useful in paediatric patients. Proper patient positioning is essential for high-quality imaging
