Diagnosi e terapia delle patologie dell'ATM: aspetti chirurgici. Diagnosis and therapy of TMJ pathologies: surgical aspects
No full textObiettivi. Il lavoro presenta le indicazioni all’intervento chirurgico e i principali procedimenti chirurgici da adottare nelle varie patologie
dell’articolazione temporo-mandibolare (ATM): l’artrocentesi, l’artroscopia, l’artroplastica funzionale, l’artroplastica totale
con protesi condilari. Materiali e metodi. Si analizzano le principali patologie di interesse chirurgico, le procedure diagnostiche,
le indicazioni terapeutiche e i principali interventi chirurgici. Risultati e conclusioni. L’ATM può essere affetta, come tutte le altre
articolazioni, da patologie che ne compromettono l’integrità anatomico-funzionale: traumi, malformazioni congenite e acquisite,
patologie sistemiche, patologie neoplastiche, patologie biomeccaniche. Il quadro clinico è sempre complesso e associato a segni
e sintomi tipici dei disordini temporo-mandibolari, rendendo spesso difficile una diagnosi differenziale. La diagnosi, quindi,
è il momento fondamentale per un corretto iter terapeutico. Basilare è riconoscere l’eziologia e il meccanismo patogenetico. Si
sottolinea in particolare l’importanza dell’individuazione del momento eziopatogenetico e del trattamento chirurgico mirato al
ripristino morfofunzionaleObjectives. The paper details the indications to surgical treatment and the main surgical procedures for different Temporomandibular Joint (TMJ) pathologies: Arthrocentesis, arthroscopy, functional arthroplasty, total arthroplasty with condylar prosthesis. Materials and methods. The main pathologies of surgical interest, as well as diagnostic procedures, therapeutic indications and surgical procedures were analysed. Results and conclusions. TMJ, just as other joints, may be affected by pathologies jeopardizing anatomical and functional integrity: Traumas, congenital and secondary malformations, systemic diseases, neoplastic pathologies, biomechanical pathologies. The clinical picture of these pathologies is always complex and associated with characteristic signs and symptoms of temporomandibular disorders, thus making a differential diagnosis often difficult. Diagnosis is the crucial step in establishing the correct therapeutic program. The identification of the etiologic and pathologic mechanism is fundamental. The authors underline the importance of determining the etiopathogenesis of TMJ disorders and of targeting surgical treatments to restore anatomical and functional integrit
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

No full textSynovial chondromatosis of the temporomandibular joint with glenoid fossa erosion: disk preservation for early anatomical recovery
No full textBackground: Synovial chondromatosis (SC) of temporo- mandibular joint is a pseudoneoplastic condition characterized by benign cartilaginous metaplasia of mesenchymal residues of synovial tissue with intra articular nodules formation. TMJ involvement is rare. Interposition of loose bodies in the intra- articular space generates a pressure that could lead to glenoid fossa erosion with intracranial extension.
Findings: The aim of the study is to present 5 SC cases with intracranial extension approached with articular disk preservation. Methods: Five patients treated from 2009 to 2018, affected by TMJ chondromatosis with intracranial extension were included. Results were compared with literature. Inclusion criteria were: CT showing glenoid fossa erosion, MRI, histological SC confir- mation, and a 2-year-follow-up. Access to superior compartment was obtained. Surgical treatment was performed removing care- fully the mass and preserving articular disk. Medial region was investigated with arthroscopy.
Findings: A 2-years-follow-up showed no swelling and pain. Patients showed a good mouth opening recovery and improvement of previous mouth limitation. Morphological study, performed through MRI and CT, showed complete anatomical TMJ recovery and total bone reconstruction of the glenoid fossa.
Conclusion: The only removal of intra articular nodules, with TMJ arthroplasty and articular disk preservation, represents a valid treatment proposal for anatomic and functional full recovery in synovial chondromatosis of the temporomandibular joint with glenoid fossa erosion
