Abstract

Objective To investigate the clinical efficacy of open radical mastoidectomy (ORM) combined with ear cavity angioplasty and mastoid cavity obliteration in treatment of cholesteatoma otitis media (COM). Methods Eighty-two patients with COM were divided into 2 groups according to surgical approach: control group (41 patients undergoing simple ORM) and observation group (41 patients undergoing ORM combined with ear cavity angioplasty and mastoid cavity obliteration). The clinical efficacy and recurrence rate between the 2 groups were compared. Results The total effective rate, dry ear rate and eardrum healing survival rate in observation group were significantly higher than those in control group: 95.12% (39/41) vs. 78.05% (32/41), 97.56% (40/41) vs. 75.61% (31/41) and 90.24% (37/41) vs. 73.17% (30/41), and there were statistical differences (P 0.05). The recurrence rate in observation group was significantly lower than that in control group: 2.44% (1/41) vs. 14.63% (6/41), and there was statistical difference (P < 0.05). Conclusions The application of ORM combined with ear cavity angioplasty and mastoid cavity obliteration in the treatment of COM has significant effect, with rapid postoperative dry ear and epithelialization, fewer complications and lower recurrence rate. It should be widely applied. Key words: Otitis media; Cholesteatoma, middle ear; Radical mastoidectomy
