Reduction genioplasty enhances quality of life in female patients with prognathism and maxillary hypoplasia undergoing bimaxillary osteotomy
No full textThe structure of the chin determines facial attractiveness and is directly linked to quality of life (QoL). In patients with prognathism and maxillary hypoplasia, bimaxillary osteotomy (BIMAX) with mandibular setback does not always lead to a more slender chin or improved aesthetics. The aim of the present study was to evaluate whether QoL differed between females undergoing BIMAX alone (group I; n = 30) and those undergoing BIMAX combined with reduction genioplasty (group II; n = 30). Presurgical and postsurgical evaluations included cephalography, photogrammetry, and the Oral Health Impact Profile with one additional domain (aesthetics). Setback of the hard tissue pogonion was significantly greater (P = 0.006) in group 11 (7.1 mm) than in group 1(2.7 mm). Only in group II were soft tissue pogonion changes highly significant (P < 0.001), amounting to a mean of 5 mm. In both groups, the QoL domains 'social disability', 'psychological discomfort', and 'dissatisfied with aesthetics' changed significantly towards lower impact scores. Changes in the latter two domains were significantly greater in group II patients than in group I patients (P = 0.021; P < 0.001) and were correlated with changes in the soft tissue pogonion in the horizontal (P = 0.024; P = 0.022) and vertical directions (P = 0.037; P = 0.042). Genioplasty addresses both psychological and aesthetic concerns, and therefore significantly enhances postsurgical QoL
Quality of Life in orthognathic surgery patients: Post-surgical improvements in aesthetics and self-confidence
No full textThe objective of this prospective study was to assess changes of Quality of Life (QoL) in patients undergoing bimaxillary orthognathic surgery. Questionnaires were based on the Oral Health Impact Profile (OHIP, items OH-1-OH-14) and three additional questions (items AD-1-3), and were completed by patients (n = 50: mean age 26.9 +/- 9.9 years) on average 9.1 +/- 2.4 months before surgery, and 121 +/- 1.4 months after surgery, using a scoring scale. Item scores describing functional limitation, physical pain, physical disability and chewing function did not change significantly, whereas item scores covering psychological discomfort and social disability domains revealed significant decreases following surgery. AD-2 "dissatisfying aesthetics" revealed the greatest difference between pre- and post-surgical scores (p < 0.001). If there was a perception of aesthetic improvement of facial features post-surgery, the benefit in QoL was generally high. The significant correlation of the pre- to post-surgical changes of item OH-5 "self conscious" to nearly all other item changes suggested that OH-5 was the most sensitive indicator for post-surgical improvement of QoL. Psychological factors and aesthetics exerted a strong influence on the patients' QoL, and determined major changes more than functional aspects did.

Costs incurred by applying computer-aided design/computer-aided manufacturing techniques for the reconstruction of maxillofacial defects
No full textThis study aims to evaluate the additional costs incurred by using a computer-aided design/computer-aided manufacturing (CAD/CAM) technique for reconstructing maxillofacial defects by analyzing typical cases. The medical charts of 11 consecutive patients who were subjected to the CAD/CAM technique were considered, and invoices from the companies providing the CAD/CAM devices were reviewed for every case. The number of devices used was significantly correlated with cost (r = 0.880; p < 0.001). Significant differences in mean costs were found between cases in which prebent reconstruction plates were used ((sic)3346.00 +/- (sic)29.00) and cases in which they were not ((sic)2534.22 +/- (sic)264.48; p < 0.001). Significant differences were also obtained between the costs of two, three and four devices, even when ignoring the cost of reconstruction plates. Additional fees provided by statutory health insurance covered a mean of 171.5% +/- 25.6% of the cost of the CAD/CAM devices. Since the additional fees provide financial compensation, we believe that the CAD/CAM technique is suited for wide application and not restricted to complex cases. Where additional fees/funds are not available, the CAD/CAM technique might be unprofitable, so the decision whether or not to use it remains a case-to-case decision with respect to cost versus benefit.

No full textSoft tissue response in orthognathic surgery patients treated by bimaxillary osteotomy: cephalometry compared with 2-D photogrammetry
No full textSince improvement of facial aesthetics after orthognathic surgery moves increasingly into the focus of patients, prediction of soft tissue response to hard tissue movement becomes essential for planning. The aim of this study was to assess the facial soft tissue response in skeletal class II and III patients undergoing orthognathic surgery and to compare the potentials of cephalometry and two-dimensional (2-D) photogrammetry for predicting soft tissue changes.Twenty-eight patients with class II relationship and 33 with class III underwent bimaxillary surgery. All subjects had available both a traced lateral cephalogram and a traced lateral photogram taken pre- and postsurgery in natural head position (median follow-up, 9.4 ± 0.6 months).Facial convexity and lower lip length were highly correlated with hard tissue movements cephalometrically in class III patients and 2-D photogrammetrically in both classes. In comparison, cephalometric correlations for class II patients were weak. Correlations of hard and soft tissue movements between pre- and postoperative corresponding landmarks in horizontal and vertical planes were significant for cephalometry and 2-D photogrammetry. No significant difference was found between cephalometry and 2-D photogrammetry with respect to soft to hard tissue movement ratios.This study revealed that cephalometry is still a feasible standard for evaluating and predicting outcomes in routine orthognathic surgery cases. Accuracy could be enhanced with 2-D photogrammetry, especially in class II patients
Clinical course and implications of congenital nasal pyriform stenosis and solitary median maxillary central incisor in a newborn: a case report
Full text linkIntroduction Congenital nasal pyriform aperture stenosis and solitary median maxillary central incisor are uncommon anomalies and are associated with further malformations. Solitary median maxillary central incisor itself has initially no impact on a child’s health, but congenital nasal pyriform aperture stenosis is a potentially life-threatening condition. Case presentation A Caucasian baby boy showed severe dyspnoea and was intubated orotracheally. Multiple anomalies were detected, including urogenital and craniofacial malformations. Computed tomography scans revealed congenital nasal pyriform aperture stenosis with a diameter of 4.9mm and a solitary median maxillary central incisor. A 3.0mm tube was inserted in his left nasal cavity, and the baby was able to breathe sufficiently and spontaneously. The nasal tube was removed after seven days, and the baby was discharged under application of decongestant drops. After seven months, the baby was readmitted with respiratory distress, and surgery was carried out using an intraoral sublabial approach. The stenotic area of the pyriform aperture was widened, and 3.0mm tubes were inserted in both nasal cavities for 10 days. Over a period of six months, no further respiratory distress has occurred. Conclusions The decision to perform surgery was delayed since the baby’s nasal breathing was adequate as a result of the insertion of a nasal tube. Since treatment depends on the severity of symptoms, it is appropriate in some cases to take a conservative approach at first, and to keep surgery as a last resort. Once a conservative approach has been selected for congenital nasal pyriform aperture stenosis, awareness of the life-threatening nature of the condition should be kept in mind, and a surgical approach must still be taken into account
A rare association: basal cell carcinoma in a vitiliginous macula
No full textToday, no proven significant association was detected between sun-exposed vitiliginous patches and non-melanotic skin cancers. In fact, the occurrence of a basal cell carcinoma (BCC) in vitiliginous patches seems to be extremely rare.We present a case of a 33-year-old female patient suffering from BCC in a vitiliginous patch on the cheek. This is the first report of the occurrence of a sclerodermiform type of BCC in a vitiliginous macula.Our case report challenges the long-standing belief that the occurrence of BCC in vitiligo is nearly impossible. However, even if this association is apparently fortuitous, our report contributes to the awareness of the risk of BCC in young patients with vitiligo
