- CONCLUSIONS: Some times TMJ ankylosis can present with atypical presentations in which bones of the skull base are involved. These are very rare and could be termed as 'skull base ankylosis'. Such cases can be surgically challenging and some surgical treatment modalities like Computer Assisted Surgery (CAS), 3D Navigation and Piezo-electric surgery could be beneficial in avoiding complications and facilitating efficient treatment.

Progressive understanding of the underlying pathophysiology of axial spondyloarthritis has successfully translated into innovative therapeutic strategies and successful management of patients in the clinic. This review summarizes the key roles of the pro-inflammatory cytokines tumor necrosis factor and interleukin-17 in the onset and progression of disease and how these cytokines are instrumental in shaping the concept that enthesitis is a key feature of axial spondyloarthritis. Advances in immunological technologies have led to the important insight that different cell populations, part of both the innate and adaptive immune system, play a key role in axial spondyloarthritis. In addition to inflammation, structural damage to the axial skeleton, in particular progressive ankylosis of the sacroiliac joints and the spine, is key to the outcome of patients. Novel data integrate the role of pro-inflammatory cytokines and enthesitis in this context.
- Ankylosis of the Temporomandibular Joint in Pediatric Patients. [Journal Article]
- JCJ Craniofac Surg 2019; 30(4):1033-1038
- CONCLUSIONS: Given the technical ease of gap arthroplasty and nonsignificant differences in ΔMIO, MIOpostop, or occurrence of re-ankylosis between gap and interpositional arthroplasty, gap arthroplasty should be considered for primary ankylosis repair in pediatric patients, with emphasis on postoperative physiotherapy to prevent recurrent-ankylosis.
- Surgical treatment of type III temporomandibular joint ankylosis with a lateral arthroplasty while retaining the medially displaced condyle. [Journal Article]
- ARAnn R Coll Surg Engl 2019 Jun 03; :1-7
- CONCLUSIONS: The released medially residual condyle can still function normally in temporomandibular joint movement and without reankylosis after a bone fusion resection. The displaced condyle should thus be preserved instead of being removed during the treatment of type III temporomandibular joint ankylosis.

- CONCLUSIONS: Ultrasound-guided lumbar SNRB plus T12 paravertebral and sacral plexus block not only satisfied the analgesia requirement of surgery, but also reduced the consumption of local anesthetic.

Intentional replantation has been used as an alternative treatment modality to tooth extraction and prosthetic replacement when conventional endodontic treatment modalities are unfeasible or contraindicated. This case report presents a successful case of intentional replantation for the mandibular first molar with an endodontic mishap. An endodontic instrument was separated in the apical third of the root canal and extended beyond its mesiobuccal root apex. Intentional replantation served as a means to remove the separated instrument. The periodontal ligament (PDL) cells were kept viable throughout the endodontic treatment using a distinctive technique, wherein a preoperative impression is used for continuous wetting with saline. Platelet-rich fibrin (PRF) was shredded and placed in the alveolar socket to enhance PDL cell reattachment and prevent ankylosis. The 2-year successful follow-up reinforced that intentional replantation can be a viable option for removal of separated instruments that lie beyond the root apex. The use of these techniques to keep PDL cells viable and the use of PRF can aid in prevention of ankylosis.

Numerical models of the human middle ear have been developed throughout the last 30 years, for different purposes. While several types of pathologies have been studied, stapedial disorders were seldomly explored. This papers aims to clarify how stapes fracture and some forms of stapes ankylosis, such as stapedial tendon ossification, augmented pyramidal eminence and bony bar presence, affect the sound transmission through the middle ear. In addition, the stapes dynamics is also analyzed by means of total displacement and first principal strain. For the purpose of the study, first, a three dimensional Finite Element model of the human middle ear is detailed and validated under normal (healthy) conditions. The model is then modified to represent the stapedial disorders of interest. A measure is established for evaluating how the disorders reduce sound transmission through the middle ear. Results of the reduction of sound transmission showed that the different forms of stapes ankylosis affect primarily low frequencies, while the stapes fracture mostly affects high frequency sound transmission. According to the results, an augmented pyramidal eminence does not restrict stapes movement unless followed by some ossification of the stapedial tendon. In addition, the question whether the fracture is in the anterior or posterior crus and the distance of the fractured part from the stapes footplate have a relevant role in the reduction of the sound transmission. Finally, the analysis of total displacement and first principal strain of the stapes helped to highlight some differences among the stapedial disorders.

The aim of autotransplantation of teeth (ATT) is to replace a lost tooth with a functional tooth within the same patient. Though it has recently become more of a recognized and viable treatment approach in dentistry, the long-term outcomes are still not well-documented. The principal author (M. Tsukiboshi) has performed more than 1,000 ATT for reasons such as treating missing teeth, deep caries, poor endodontic results and periodontitis, over the past 30 years in private practice. During the course of private practice, two separate analyses were performed on a total of 319 cases with follow-up ranging from two to 26 years. Results showed a tendency toward higher success rates in younger patients: the success rate was highest in ATT performed on immature teeth (about 95%), about 90% in patients less than 30 years of age and approximately 80% in patients older than 30. The failures were most often due to replacement resorption (i.e., ankylosis-related resorption). The purpose of this case series is to show successful long-term outcomes of ATT, as well as to provide clinical insights and describe tendencies seen over the course of 30 years of experience performing ATT.
