Objectives:
Mastoid reconstruction principle had been described to overcome problems of chronic discharging cavity. Different materials were used; nonbiologic materials seem to be less preferred. Platelet-rich plasma (PRP) could promote the regeneration of mineralized tissues. In this work, the authors present a simple and easy technique for mastoid reconstruction with PRP and cortical bone pate.
Methods:
The study design is a case series. Patients had mastoid reconstruction after canal wall down mastoidectomy using PRP and cortical bone pate.
Results:
This study included 21 patients: 9 males, and 12 females. Sixteen patients had left side disease. All surgical procedures were conducted smoothly within 90 to 135 minutes with no stressful events had been reported. At 12 to 16 months of follow-up, external canal stenosis and mastoid fistulas were not reported. Good healing of the tympanic membrane was seen in 18 patients. No radiological signs suggestive of recurrence were detected and the reconstructed mastoid cavity was smooth and well aerated. Residual tympanic membrane perforations were detected in 3 patients.
Conclusion:
Autologous materials (PRP and bone pate pate) after canal wall down mastoidectomy appear to be a reliable and effective choice for mastoid reconstruction.
