Abstract

Introduction: Chronic Suppurative Otitis Media (CSOM) cholesteatoma type with deterioration of the posterior ear canal wall is treated with Canal Wall Down (CWD) mastoidectomy followed by reconstruction of the posterior ear canal wall with Platelet-Rich Plasma (PRP) and bone cartilage. Combining PRP with soft tissue and bone cartilage may stimulate the mineralization of regenerating tissue. Purpose: To achieve an effective combination of methods, such as CWD mastoidectomy with posterior ear canal wall reconstruction using PRP, bone cartilage, and soft tissue, to improve wound healing, resulting in a smooth mastoid cavity with no complications. Case report: of a 53-year-old man with CSOM suspicious cholesteatoma type at the left ear and devastation of the posterior ear canal wall treated with CWD mastoidectomy and reconstruction of the posterior ear canal wall using PRP, bone cartilage, and soft tissue. Method: Literature searching through the Cochrane database, Pubmed, and Google Scholar, using keywords of platelet-rich plasma, posterior ear canal wall reconstruction, mastoid obliteration, and canal wall down mastoidectomy. Result: The selection process based on inclusion and exclusion criteria yielded only one pertinent study. The patient underwent mastoid reconstruction using PRP and a cortical bone plate following CWD mastoidectomy. This study included 21 patients, including 9 men and 12 women. Sixteen patients had the disease on the left side. Within ninety to one hundred and thirty-five minutes, all surgical procedures are performed without incident. External canal stenosis and mastoid fistula were not discovered at 12 to 16 months of follow-up. In 18 patients, the tympanic membrane healed properly. There were no radiological indications of recurrence, and the reconstructed mastoid cavity was smooth and well-ventilated. In three patients, residual tympanic membrane perforations were detected. Conclusion: When PRP, bone cartilage, and soft tissue are used to rebuild the back wall of the ear canal, the wound heals faster and there are no problems. The result is a smooth surface in the mastoid cavity. Platelet-rich plasma, mastoid obliteration, and posterior ear canal wall reconstruction are the key terms.
