The effect of post-auricular canal wall down mastoidectomy on the position of the auricle.

OBJECTIVE: This study aimed to investigate the effect of surgical incision on the auricle position in patients undergoing canal wall down mastoidectomy to treat chronic otitis media. METHODS: Thirty-four patients who had undergone canal wall down mastoidectomy with a post-auricular incision approach were included in the study. Patients who had a previous auricle deformity, who underwent limited mastoidectomy surgery or mastoid obliteration, or who were younger than 18 years of age were excluded. The distances of the upper and middle parts of the auricle to the mastoid were measured. RESULTS: Measurements in the first post-operative year were found to be 13.15 ± 3.59 mm in the upper region and 16.29 ± 5.00 mm in the middle region. It was observed that the auricle was approaching the mastoid area in both regions. CONCLUSION: In patients undergoing radical mastoidectomy, the distance between the auricle and the mastoid may decrease, leading to narrowing of the auriculo-cephalic angle.

Reconstruction of ear canal wall with superior pedicled composite multi-fractured osteoperiosteal flap: a new technique and preliminary outcomes.

OBJECTIVE: This study evaluated the functional results of the superior pedicled composite multi-fractured osteoperiosteal flap technique. This method is a novel technique for the reconstruction of the external auditory canal. The study also examined the effect of the superior pedicled composite multi-fractured osteoperiosteal flap technique on patients' disease-related quality of life. METHOD: A total of 37 patients who underwent the superior pedicled composite multi-fractured osteoperiosteal flap technique were enrolled in the study. Their functional hearing results and disease-related quality of life scores were evaluated. RESULTS: A significant improvement was observed in the patients' hearing scores at the post-operative sixth month relative to the pre-operative period, and the patients' disease-related quality of life increased significantly. CONCLUSION: The superior pedicled composite multi-fractured osteoperiosteal flap method can be safely used, especially in patients undergoing retrograde mastoidectomy because of limited cholesteatoma. This method contributes to improving patients' hearing levels and disease-related quality of life.

Osteoclastic activity in chronic otitis media with cholesteatoma-related bone destruction.

BACKGROUND: Cholesteatoma-related bone destruction is the cause of many complications due to chronic otitis media. This study aimed to evaluate osteoclastic activity in cholesteatoma-related bone destruction using tartrate-resistant acid phosphatase 5b, an enzyme specific to osteoclastic activity. METHOD: Seventy-two patients diagnosed with chronic otitis media were included in this study and were divided into two groups: with and without bone destruction. The blood serum and tissue tartrate-resistant acid phosphatase 5b levels from both groups were compared. RESULTS: There were no significant differences in the level of serum enzymes between both groups. However, in tissue samples, tartrate-resistant acid phosphatase 5b levels were significantly lower in the bone destruction group than the group without bone destruction. CONCLUSION: This study determined that the level of tartrate-resistant acid phosphatase 5b, a specific enzyme for osteoclastic activity in cholesteatoma-related bone destruction, is locally decreased. This data suggests that osteoclastic activity may decrease in cholesteatoma-related bone destruction. However, further experimental and clinical studies are required to clarify this highly complex mechanism.
