Asociación del tamaño de la vía aérea superior y presencia de osteoartritis en estudios de haz cónico Cone Beam del departamento de radiología de la Universidad de Cuenca. Un estudio retrospectivo

Abstract

Osteoarthrosis of the temporomandibular joint (OA TMJ) is considered the most common and slowly progressive joint disease 1. Its prevalence ranges from 17.97% - 77.23% 2. OA TMJ and airway appear to have a bidirectional association, when there is severe destruction of the condyle generated by OA TMJ, it is possible to clinically present a retrognathic mandible and a hyperdivergent facial profile and decreased airway dimensions3. The aim is to associate upper airway volume with the presence of osteoarthritis in cone beam tomographic studies of the Radiology Department of the University of Cuenca. Materials and methods: 201 tomographic studies (402 results), aged 18 to 65 years, were analyzed for the presence of OA ATM (Wilkes criteria) and then for airway volume (Romexis ® 6.4.1. Planmeca). Results: Women are more predisposed, with 91 affected condyles (22.6%). Of these, 45 (73.8%) present osteoarthrosis in the right condyle and 46 (71.9%) in the left. The left condyle was the most affected with 64 (31.8%). The airway volume in people with OA: right condyle nasopharynx 3495.2±1268.3cm³, oropharynx 9321.8±4577.7cm³ and laryngopharynx of 3045.7 ±1218.0cm³ and in the left nasopharynx 3636.7±1421.4cm3, oropharynx 9346.7±4512.3cm³ and laryngopharynx 3005.9±1223.8cm3. Conclusions: Females have a greater predilection for presenting with TMJ OA, with an age range of 18-28 years, with the left condyle being the one with the greatest predilection compared to the right. Patients with osteoarthrosis presented significant reductions in upper airway volumes.
