Comparison of Anatomical Maxillary Sinus Implant and Polydioxanone Sheets in Treatment of Orbital Floor Blowout Fractures: A Retrospective Cohort Study
Source abstract
Abstract
Background: Orbital floor blowout fractures (OFBF) can have serious consequences for the patient. Selecting the right treatment method and materials is essential. Krenkel’s maxillary sinus implant has been used successfully for more than 40 years in clinical practice. The aim of this study was to evaluate the long-term outcome of this implant compared to polydioxanone (PDS) sheets. Material and methods: This retrospective study examined a cohort of 82 OFBF patients over a seven-year period. Clinical and geometric data were collected. Defect size, location, and the volume of the herniated tissue were measured from conventional computer tomography (CT) or cone beam computer tomography (CBCT) scans. The relationship between ophthalmologic rehabilitation and treatment modality was analyzed using logistic regression. Results: The study included 82 patients, 28% female and 72% male, with a median age of 45.2 years. Defect size and hernia volume correlated with preoperative ophthalmological symptoms. At follow-up, 14.8% in the implant group and 28.6% in the PDS group showed mild visual impairment, with no severe diplopia. Conclusions: Our results suggest this method is a reliable and effective solution for repairing OFBFs and ophthalmologic rehabilitation. However, further research in a clinical controlled trial is needed.
