An experimental model of maxillary sinus ballooning in rabbits following surgically induced trauma

Relevance. This study explores the characteristics of maxillary sinus ballooning in rabbits following surgically induced trauma. Materials and methods. The experimental setup included a physiodispenser, turbine handpiece, disc burs, bellied scalpel, hemostatic clamp, anatomical forceps, biodegradable suture, balloon tampon, and the LAKK-M laser Doppler flowmetry system. Results. Inducing surgical trauma to the anterior wall of the maxillary sinus and inserting a balloon catheter into the sinus via the nasal passage. The feasibility of investigating microcirculation in the maxillary sinus was assessed. Macro- and microscopic examinations were performed on the maxillary sinus tissue complex of three rabbits (mean body weight: 3200 ± 600 g) at the sites of balloon contact with the surgically injured area. Conclusion. The findings confirm that rabbits with a mean body weight of 3200 ± 600 g are a suitable model for studying the effects of maxillary sinus ballooning following surgical trauma. These results are of relevance to both maxillofacial surgery and otorhinolaryngology.
