Atlas dislocation after transverse ligament injury is one of the most rare types of trauma to the upper cervical level. If magnetic resonance imaging of the craniovertebral junction reveals the Kassam line passing through the cervix of the odontoid process, a transnasal approach can be used for surgical treatment. Here, we present a case in which an endoscopic endonasal approach was used to treat chronic traumatic transligamentous atlas dislocation. A 26-year-old male underwent two-stage surgical treatment; during the first stage, posterior decompression and fixation were performed under halo immobilization. In the second stage, a transnasal endoscopic approach to the odontoid process was used. A transnasal approach permitted complete decompression of the medulla oblongata and facilitated early extubation of the patient without any postoperative complications such as respiratory or pharyngopalatine deficiency. The patient was discharged in good condition 9 days after the surgery.

Velocardiofacial syndrome (VCFs) is a rare congenital disease with an incidence of 1:4000 to 1:6000. Previous studies have found that the abnormality is associated with 22qDS. As reported at the international VCFs conference held in 2006, >180 phenotypes have been identified with this syndrome. Accordingly, there is a wide range of clinical manifestations including congenital defects of the heart and palate, immune deficiencies, psychiatric illness, and speech, learning, and cognitive disabilities Among all the symptoms above, however, pharyngopalatine dysplasia has been observed in nearly every patient. Patients with VCFs often have velopharyngeal insufficiency, which may cause serious disorders in functional speech, with poor intelligibility, a glottal stop with hypernasality and a pharyngeal fricative, and dropping and weakening of consonants. Most also show defects in language learning. Therefore, specialized speech therapy is essential for patients with VCFs, mainly focused on correction of abnormal pronunciation. Long-term clinical experience has shown that speech therapy is based on 2 components: velopharyngeal function and behavior therapy. Our study focused mainly on establishing a corrective behavior guidance model of pronunciation for patients with VCFs.
- Three-dimensional reconstruction of soft palate modeling from subject-specific magnetic resonance imaging data. [Journal Article]
- SBSleep Breath 2012; 16(4):1113-9
- CONCLUSIONS: The same procedure was used to build up a generic reference model of the dentition, tongue, mandible and airway from a mixture of medical records (CT and dental casts) of the same subject. This manual segmentation method eliminated the common errors that occur from an automatic segmentation although it was more time-consuming. It remains a fundamental process for analyzing the dynamic interaction between anatomical components in the oral, pharyngeal, and laryngeal areas.

- ZYZhonghua Yi Xue Za Zhi 2009 Dec 29; 89(48):3405-8
- CONCLUSIONS: VPP remodels palatopharyngeal region through the design of incision, the management of pharyngopalatine arch tonsillectomy and the suture of laterapharynx mucisae. This surgical procedure can obviously upgrade the velum platinum, enlarge the oropharyngeal airway effectively. It is a significant modified-UPPP surgical technique.

- CONCLUSIONS: The children that underwent adenotonsillectomy acquired a higher weight-height growth potential in relation to those children who were not operated.

A modified uvulopalatopharyngoplasty (UPPP) was carried out between January 1992 and December 2003 at the ENT Department of the Inselspital in Bern in 146 patients with habitual or complicated rhonchopathy. The operation consisted of a classical tonsillectomy or residual tonsil resection and additional shortening of the uvula. The natural mucosal fold between the uvula and the upper pole of the tonsils was carefully preserved. A wide opening to the rhinopharynx was created by asymmetric suturing of the glossopalantine and pharyngopalatine arches. A retrospective questionnaire with regard to rhonchopathy, phases of apnea, daytime drowsiness, obstruction of nasal breathing, long-term complications and patient satisfaction was used to evaluate the short-term and long-term effectiveness of the modified UPPP as well as the incidence of adverse side effects. Complete postoperative courses were evaluated in 116 patients. Surgical complications were restricted to one case with postoperative hemorrhage. A velum insufficiency or postoperative rhinopharyngeal stenosis did not occur. Eighty-three patients (72%) confirmed a persistent suppression or substantial improvement of the rhonchopathy. Disappearance or decrease of sleep apnea was confirmed in 12 (63%) out of 19 postoperative polysomnographic follow-up investigations. Long-term complications occurred in a total of 27 (23%) of 116 patients. They were confined to minor problems such as dryness of the mouth (n = 12), slight difficulty in swallowing (n = 7), discrete speech disturbances (n = 1), and slight pharyngeal dysesthesias (n = 7) with feeling of a lump in the throat and compulsive clearing of the throat. Eighty-five patients (73%) reported that they were satisfied with the postoperative result even several years after the operation. Looking back, 31 patients (27%) would no longer have the operation performed. The inadequate result of the rhonchopathy was specified as the reason by 21 patients. Ten patients had unpleasant memories of the operation because of intensive postoperative pain. Snoring and apneic phases are suppressed or improved by non-traumatic UPPP in the majority of patients. This effect persisted even years after the operation.

The vocal tract from the glottis to the lips is considered to he a resonator and the voice is changeable depending upon the shape of the vocal tract. In this report, we examined the change in pharyngeal size and acoustic feature of voice after tonsillectomy.
