Abstract
Background. The treatment of middle ear cholesteatoma requires surgical treatment and the reconstruction of the temporal bone, which represents an ongoing problem. Otologists have focused on the research of materials allowing an airy middle ear and the preservation of hearing function to reconstruct the temporal bone. Methods. This study evaluated the effect of cyclosporin A (CsA) and a combined biomaterial in the healing process of postoperative temporal bone defects in an animal model. Cultured human Bone Marrow Mesenchymal Stromal Cells (hBM-MSCs) were mixed with hydroxyapatite (Cem-Ostetic®), and subsequently applied as a bone substitute after middle ear surgery, showing that the therapeutic potential of hBM-MSCs associated with bone regeneration and replacement is directly influenced by CsA, confirming that it promotes the survival of MSCs in vivo. Results. The therapeutic efficacy of the combination of MSCs with CsA is greater than the sole application of MSCs in a hydroxyapatite carrier. Conclusion. The reconstruction of a temporal bone defect using hBM-MSCs requires an immunosuppressant to improve the results of treatment.

Abstract
Temporal bone reconstruction is a persisting problem following middle ear cholesteatoma surgery. Seeking to advance the clinical transfer of stem cell therapy we attempted the reconstruction of temporal bone using a composite bioartificial graft based on a hydroxyapatite bone scaffold combined with human bone marrow-derived mesenchymal stromal cells (hBM-MSCs). The aim of this study was to evaluate the effect of the combined biomaterial on the healing of postoperative temporal bone defects and the preservation of physiological hearing functions in a guinea pig model. The treatment's effect could be observed at 1 and 2 months after implantation of the biomaterial, as opposed to the control group. The clinical evaluation of our results included animal survival, clinical signs of an inflammatory response, and exploration of the tympanic bulla. Osteogenesis, angiogenesis, and inflammation were evaluated by histopathological analyses, whereas hBM-MSCs survival was evaluated by immunofluorescence assays. Hearing capacity was evaluated by objective audiometric methods, i.e. auditory brainstem responses and otoacoustic emission. Our study shows that hBM-MSCs, in combination with hydroxyapatite scaffolds, improves the repair of bone defects providing a safe and effective alternative in their treatment following middle ear surgery due to cholesteatoma.

Skoloudik L, Kalfert D, Valenta T, Chrobok V. Relation between adenoid size and otitis media with effusion. Eur Ann Otorhinolaryngol Head Neck Dis 2018; 135:399-402. [PMID: 30290997 DOI: 10.1016/j.anorl.2017.11.011] [Citation(s) in RCA: 24] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/14/2017] [Revised: 11/07/2017] [Accepted: 11/13/2017] [Indexed: 12/21/2022]
Abstract
AIMS This study compares the efficacy of adenoidectomy on otitis media with effusion (OME) in patients with different size of adenoids and the connection between differently sized adenoids and middle ear effusion. MATERIAL AND METHODS Children with a history of at least 3 months' OME underwent adenoidectomy and myringotomy without the insertion of a tympanostomy tube. Treatment assignment was stratified by adenoids' size causing choanal obstruction (grade I-III) and according to Eustachian tube ostium obstruction (grade A-C). The subjects were followed for 12 months. RESULTS Adenoidectomy was significantly more effective in children with adenoids in contact with torus tubarius (grade B, C) compared to those with small adenoids without contact (P<0.001). The volume of the adenoids was irrelevant (P=0.146). The size of adenoids did not affect the viscosity of the middle ear secretion. The distribution of mucous and serous secretion was not dependent on the size of adenoids; the efficacy of adenoidectomy was 82% in mucous as well as serous secretion. CONCLUSION The relation between adenoids and torus tubarius is more important than the volume of the adenoids. The viscosity of middle ear fluids (serous or mucous) did not influence the rate of treatment efficacy.

Abstract
Canal wall down mastoidectomy is one of the most effective treatments for cholesteatoma. However, it results in anatomical changes in the external and middle ear with a negative impact on the patient's quality of life. To provide complete closure of the mastoid cavity and normalize the anatomy of the middle and external ear, we used human multipotent mesenchymal stromal cells (hMSCs), GMP grade, in a guinea pig model. A method for preparing a biomaterial composed of hMSCs, hydroxyapatite, and tissue glue was developed. Animals from the treated group were implanted with biomaterial composed of hydroxyapatite and hMSCs, while animals in the control group received hydroxyapatite alone. When compared to controls, the group implanted with hMSCs showed a significantly higher ratio of new bone formation ( p = 0.00174), as well as a significantly higher volume percentage of new immature bone ( p = 0.00166). Our results proved a beneficial effect of hMSCs on temporal bone formation and provided a promising tool to improve the quality of life of patients after canal wall down mastoidectomy by hMSC implantation.
