OBJECTIVETo establish the quantitative diagnostic criteria for cranio-orbito-zygomatic deformity (COZD).

METHODSComputer-assisted three-dimensional (3-D) CT measurement was performed in 30 cases with unilateral COZD. The differences of the measurement data between the affected and unaffected sides were analyzed. Then the patients were diagnosed and classified according to the affected bone, soft tissue and conjunctival sac. Based on the quantitative diagnosis, 8 patients underwent surgery to test the clinical practicability of the diagnostic criteria.

RESULTSThe quantitative diagnostic criteria for COZD could reflect the affected area and the corresponding severity of deformity. It helped to preoperative design and to predict movement of osteotomy segment and. the soft tissue volume needed for augmentation. Good postoperative results were achieved.

CONCLUSIONSThe quantitative diagnostic criteria for COZD can describe the affect area and severity of deformity in detail. It is very practical in the guidance of clinical treatment.

OBJECTIVETo summarize the methods and experiences in surgical treatment of hemifacial microsomia.

METHODSFifty-eight cases of hemifacial microsomia that have been treated by plastic and reconstructive surgery and followed-up in our department during last 20 years have been reviewed. Every patient's characteristic was assessed by physical examination, photography, craniofacial cephalometry before planned the method of surgery. Different surgical treatments were chosen according to the side and the structures involved in the abnormalities and the severity of hemifacial microsomia, and the cases were followed up since 3 months after the treatments. The follow-up lean of midline of the lower 1/3 face with that before treatment is compared. The degrees of patients' and surgeons' satisfactions with the treatments were evaluated respectively.

RESULTSThe average angle of lean of midline of skeletal and soft tissue of the lower 1/3 face decreased 4.2 degrees and 2.9 degrees respectively after treatment. Fifty (82.6%) cases satisfied with the outcome of the surgical treatment and surgeons satisfied with 84.5% of the outcome of all the cases.

CONCLUSIONSIndividual surgical treatment based on the side and the structures involved in the abnormalities can effectively correct facial asymmetry of hemifacial microsomia.

OBJECTIVETo evaluate the 3-D position changes of periorbital structures after midface distraction osteogenesis in patients with Crouzon syndrome.

METHODSThe CT data of 8 cases who had accepted the midface distraction osteogenesis following Le Fort III osteotomy were retrospectively analyzed. The patients were averagely 11.9 years old, and the CT was performed before and one year after operation. After 3-D image reconstruction, a right-hand coordinate system based on the preoperational Frankfurt Plane was then established. The pre- and post-operative positions of the superior orbit point (SOr), inferior orbit point (IOr), median orbit point (MOr), lateral orbit point (LOr), anterior ocularis point (AO), ocularis eyeball point (PO) and the four insertion ocularis rectus were documented and compared. The positions of these marked points in normal controls were also documented and compared with those in patients.

RESULTSAfter midface distraction osteogenesis, the position of AO was not changed significantly on the y-axis and z-axis, but the distance between two AO points on x-axis was reduced by 3.40 mm; IOr moved averagely 12.24 mm on y-axis and 4.25 mm on z-axis, MOr moved averagely 10.11 mm on y-axis and 2.80 mm on z-axis, LOr moved averagely 9.86 mm on y-axis and 2.31 mm on z-axis. The Inferior Rectus attachment moved averagely 3.63 mm on y-axis and 2.98 mm on z-axis. No other significant change was observed on other marked points.

CONCLUSIONSMidface distraction osteogenesis following Le Fort III osteotomy can significantly move the medial, lateral and inferior peri-orbital bone structure anteriorly and inferiorly. The eyeballs have no markedly sagittal position changes after distraction except slight medial, downwards movements and anterior-upwards rotations.

OBJECTIVETo investigate the therapeutic effects of upper airway stenosis after Le Fort III osteotomy and midfacial distraction osteogenesis (DO).

METHODSEleven cases (age, 5-16 yrs) with severe midface dysostosis complicated with exophthalmos, anterior crossbite and upper airway stenosis were treated by using Le Fort III osteotomy and midfacial DO from August 2000 to February 2007. The 3D reconstruction of the upper-airway from CT data was used to evaluate the upper airway volume before and after the operation. And meanwhile polysomnography was carried out to demonstrate the upper airway functional changes.

RESULTSThere was a 64.3% mean increase [mean, (9.13 +/- 6.94) ml, P < 0.05] in upper airway volume in the 11 cases after the operations. It showed that there was significant improvements in the indexes of polysomnography after the operations, such as apnea and hypopnea index, average SaO2, minimum oxygen saturation and snore index.

CONCLUSIONSThe Le Fort III osteotomy and midfacial distraction osteogenesis can efficiently relieve the symptoms of upper-airway stenosis in severe midfacial dysostosis.

OBJECTIVETo diagnose and classify the congenital craniofacial cleft with a uniform scale is helpful to evaluate the abnormality and select the repairing methods.

METHODSWe analyzed 81 cases of congenital craniofacial cleft basically using Tessier craniofacial cleft classification. Furthermore, according to the position of soft tissue or bone, the character and degree of clefts or dysplasia and the results of CT scanning, we subdivided the congenital deformities based on S (skin), T (tissue), and O (OS). Arabic numerals were used to express the degree of the abnormality.

RESULTSOf all the cases analyzed with the STO classification, No. III and IV clefts are often seen in the infraorbital region (24.70%). No. IX and X clefts are mostly seen in the supraorbital region (38.27%). The relationship between the cleft types and involved tissue has not been found.

CONCLUSIONSThe STO classification reinforces Tessier classification. It offers the basis for craniofacial cleft repair.

OBJECTIVETo observe the therapeutic effects of Le Fort III osteotomy and midface distraction osteogenesis (DO) on the upper-airway narrow.

METHODSSince 2000, 11 cases (10 cases of Crouzon syndrome and 1 case of Apert syndrome) with severe midface deficiency were treated with Le Fort III osteotomy and midface DO. The section area of different parts of upper-airway were tested by computer assistants image measurement preoperatively and postoperatively. Some patients received sleep function monitoring.

RESULTSThe face appearance and the function of upper-airway improved significantly after Le Fort III osteotomy and Midface DO. The section area at the level of posterior nasal spine and uvula increased obviously after treatment (P < 0.05), however the section area at the level of epiglottis and separation between airway and esophagus were not obviously enlarged (P > 0.05).

CONCLUSIONSMidface DO after Le Fort III osteotomy can effectively improve the upper-airway narrow, especially the upper part from uvula.

A 26-year-old male presented with tremor of bilateral shoulders and hands as the major symptom and also had cognitive and emotional abnormalities for more than 1 year, who was diagnosed as cerebral hepatolenticular degeneration (HLD) in Tongji Hospital of Huazhong University of Science and Technology in October 2021. The serum ceruloplasmin and urine copper levels of the patient were 0.023 g/L and 3760.00 μg/24 h, respectively, and the Kayser-Fleischer (K-F) ring was seen in the cornea. Genetic testing revealed a homozygous mutation of ATP7B gene c.2975C>T (p.Pro992Leu), while transcranial sonography (TCS) showed lenticular nucleus hyper-echogenicity. The literature was searched using hepatolenticular degeneration and transcranial sonography as key words; and 9 articles involving 150 HLD cases were obtained. The lenticular nucleus hyper-echogenicity was presented in 76.9% HLD patients (150/195), while only in 12.7% healthy subjects (17/134) ( P<0.001), suggesting that advanced transcranial sonography can detect the metal deposition and may be used for diagnosis of cerebral HLD.

Purpose: This study investigated the value of synchronous tele-ultrasonography (TUS) for naive operators in thyroid ultrasonography (US) examinations. Methods: Ninety-seven patients were included in this prospective, parallel-controlled trial. Thyroid scanning and diagnosis were completed by resident A independently, resident B with guidance from a US expert through synchronous TUS, and an on-site US expert. The on-site expert’s findings constituted the reference standard. Two other off-site US experts analyzed all data in a blind manner. Inter-operator consistency between the two residents and the on-site US expert for thyroid size measurements, nodule measurements, nodule features, American College of Radiology (ACR) Thyroid Imaging Reporting and Data System (TI-RADS) categories, and image quality was compared. Two questionnaires were completed to evaluate the clinical benefit. Results: Resident B detected more nodules consistent with the on-site expert than resident A did (89.4% vs. 56.5%, P<0.001). Resident B achieved excellent consistency with the on-site expert in terms of ACR TI-RADS categories, nodule composition, shape, echogenic foci, and vascularity (all intra-class correlation coefficients [ICCs] >0.75), while resident A achieved lower consistency in ACR TI-RADS categories, composition, echogenicity, margin, echogenic foci, and vascularity (all ICCs 0.40-0.75). Residents A and B had excellent consistency in target nodule measurements (all ICCs >0.75). Resident B achieved better performance than resident A for gray values, time gain compensation, depth, color Doppler adjustment, and the visibility of key information (all P<0.05). Furthermore, 61.9% (60/97) of patients accepted synchronous TUS, and 59.8% (58/97) patients were willing to pay for it. Conclusion Synchronous TUS can help inexperienced residents achieve comparable thyroid diagnostic capability to a US expert.
