    Abstract:
    OBJECTIVE: The MO-meatocanalplasty is the oblique modification of the M-meatoplasty. The MO-meatocanalplasty was designed to address the superior quadrants of the meatus and the bony canal without the need for a retro-auricular incision. This retrospective analysis was performed to evaluate the long-term results of the MO-meatocanalplasty in patients with a narrow external auditory canal (EAC) with recurrent otitis externa or in patients unable to wear a hearing aid. METHODS: Twenty-two ears in twenty consecutive patients who received a MO-meatocanalplasty for a narrow EAC with recurrent otitis externa or the inability to wear a hearing aid were analysed retrospectively. There were no patients included with any type of previous or planned second stage tympanoplasty procedures. A follow-up period of 3 years was analysed for postoperative recurrent narrowing, the self-cleaning capacity of the EAC, the recurrence of otitis externa, the inability to wear a hearing aid, change in hearing level and for all types of aesthetical complaints. RESULTS: The MO-meatocanalplasty procedure was effective in 82% (n = 18). Postoperative recurrent narrowing was detected in 9% (n = 2). Insufficient self-cleaning capacity of the EAC was 9.1% (n = 2). The ability to wear a hearing aid was restored in all patients with the need for a hearing aid. No aesthetical complaints were reported. CONCLUSION: The MO-meatocanalplasty is an effective, safe and aesthetical accepted procedure to address the narrow meatus and external auditory canal. With this procedure, there is no need for a retro-auricular incision in order to create a well aerated, dry and self-cleaning EAC in patients with a narrow EAC with recurrent otitis externa or in patient with the inability to wear a hearing aid.
