ABSTRACT
Abstract. Introduction. Bone defects of the anterior wall of the external auditory canal (EAC), developing against the background of inflammatory processes of the external and middle ear, are characterized by a non-specific symptom complex and require surgical intervention to prevent complications both from the ear and the temporomandibular joint. Various materials are used for reconstruction of the EAC anterior wall: autologous cartilage, temporal muscle fascia, polyethylene, titanium or collagen mesh. Objective. To improve the effectiveness of surgical treatment of defects in the anterior wall of the external auditory canal. Patients and Methods. From December 2023 to December 2024, 15 patients (8 children, 7 adults) with pathology of the external and middle ear with destruction of the EAC anterior wall underwent surgical treatment at the National Medical Research Center for Otorhinolaryngology of the Federal Medical and Biological Agency of Russia. Autologous cartilage/bone plates and glass ionomer cement were used to close the defects of the temporomandibular joint. Results. Surgical treatment was performed on 5 patients with dermoid cyst of the middle ear, 4 patients with paraganglioma of the temporal bone, and 6 patients with chronic suppurative otitis media. After the sanitizing stage, reconstruction of the temporomandibular joint wall was performed using remnants of the incus or autologous cartilage if the size of the defect was less than 3 mm, and fragments of autologous bone in the case of more extensive damage. The bone graft was additionally fixed within the defect using glass ionomer cement. Follow-up multi-slice computed tomography of the temporal bones in the postoperative period indicated the success of the reconstruction performed. Conclusions. Reconstruction of defects in the anterior wall of the EAC with autologous tissues is effective and minimizes the risk of graft rejection. Additional fixation with glass ionomer cement ensures reliable closure and prevents graft displacement.
