Immobility, fixation, or paralysis of the vocal folds is an ominous sign when encountered in the clinics. This may be due to a variety of diseases, lesions, injuries, or vascular compromise which may affect the integrity and physiologic mechanism of the vocal folds. The common etiologies include infectious processes such as laryngeal or pulmonary tuberculosis (PTB), malignancy or neoplasms, central problems such as cerebrovascular accidents (CVA), stroke and others.1,2,3 The problem should be addressed immediately because this potentially life threatening and imminent narrowing of the glottic opening may lead to respiratory distress. Vocal fold paralysis due to compression of the recurrent laryngeal nerve from PTB and laryngeal cancer are perennially seen in clinical practice, but immobility of the vocal folds due to cricoarytenoid joint fixation or ankylosis is seldom seen and appreciated. Hence, we present a case of bilateral cricoarytenoid joint ankylosis and discuss its etiology, pathophysiology, differential diagnoses, ancillary procedures, and management.
Ankylosis

The clinical diagnosis of ankylosis can be made only when the affected tooth gives positive evidence of an inability to move. The inability to move is demonstrated either as a failure of the tooth to move with normal vertical dental alveolar growth or a failure of the tooth to move when the tooth is subjected to an orthodontic force system. This case report describes the autotransplantation of an ankylosed maxillary canine.

OBJECTIVES: To present a case of bilateral temporomandibular joint ankylosis that was managed successfully through gap arthroplasty. METHODS: Design: Case Report Setting: Tertiary Government Hospital Patient: One RESULTS:A 25-year-old man presented with inability to open his mouth for 18 years after direct trauma to his chin. CT scan showed bilateral bony fusion of condyles to glenoid fossae, hypertrophic sclerosis and fusion of the condylar heads to the temporal bones. He underwent bilateral gap arthroplasty via preauricular approach with creation of a 15 mm space on the mandibular fossa. As of latest follow up, the patient maintained an inter-alveolar distance of 30 mm for five months postoperatively through continuous aggressive mouth opening exercises. CONCLUSION:Gap arthroplasty may be an efficient procedure for temporomandibular joint ankylosis in achieving satisfactory post-operative inter-alveolar opening and articular function. Early and meticulous rehabilitation is required to prevent relapse. Long-term follow up is recommended to document possible recurrence.

This clinical note introduces a method to assist surgeons in performing single-tooth dento-osseous osteotomy. For use in this method, a surgical guide was manufactured using computer-aided design/computer-aided manufacturing technology and was based on preoperative surgical simulation data. This method was highly conducive to successful single-tooth dento-osseous segmental osteotomy.

Many kinds of operations have been devised to treat Kienböck's disease with variable results. But no one have mentioned about the advantage of early motion in distraction to prevent the fibro-osseous ankylosis and carpal collapse. Two cases with Kienböck's disease were treated by the complete excision of the lunate and replacement of it with pronator quadratus muscle pedicled rectangular bone graft. Once these procedures were accomplished, the distraction-motion devices were used to maintain the joint surfaces separated at predetermined distances while kinematically normal joint motion was gradually restored. Although the experience is limited to two cases, the final results seem to be very promising.

PURPOSE: The purpose of this study was to investigate the reosseointegration periods when the rough surface implants, which had complete bone-implant ankylosis, suddenly losed the osseointegration. MATERIALS AND METHODS: The implants with RBM surface treatment were inserted into both tibias of 23 rabbits. Two implants were submerged into each side. After six weeks, the primary removal torque was measured by Digital torque gauge, and then the implants were replaced and submerged to estimate the level of reosseointegration. After assigned healing periods for each group, the removal torque was measured again. BIC (Bone-Implant contact, %) ratio was measured through histomorphometric analysis.Paired t-test was processed by SPSS 14.0. One-way ANOVA and Tukey's post-hoc test was processed to analyze statistically significant differences among the groups. RESULTS: In comparison with the primary removal torque, the secondary removal torque was increased after 11 days and significantly increased from 2 weeks. In fluorochrome labeling, the origin of mineralization was observed after 7 days, which showed as fluorescent bands around the boneimplant interfaces. After 11 days, the bone formation was apparent, and it is increased continuously with the passage of the time. CONCLUSION: In 11 days after the implant replacement, the secondary removal torque was almost as same as the primary value, and was significantly higher from 2 weeks. The mineralized shapes were observed in 7 days after the implant replacement, and then thebone formation appeared visibly in 11 days.

Impaction with a severely dilacerated root is seldom reported, especially in the maxillary incisor. It is probably because of the high clinical difficulty associated with bringing the dilacerated tooth into proper position, and the high chance of failure due to ankylosis, external root resorption, and root exposure after orthodontic traction. Even the successful cases may need periodontal surgery to improve the unesthetic gingival shape. However, it has previously been reported that an impacted maxillary central incisor was successfully treated by proper crown exposure and orthodontic traction. This article presents a case of an invertedly impacted maxillary right central incisor with a developing dilacerated root, which was aligned into proper position after orthodontic traction composed of two stages of a closed eruption technique.
