Introduction
A disruption of the ossicular chain of the middle ear causes conductive hearing loss. Ossicular reconstruction is performed to restore hearings in those patients with congenital ossicular chain anomaly or ossicular chain disruption caused by chronic otitis media or cholesteatoma.
A study from Japan with 52 auditory ossicular malformation revealed that 44% of the patients had a fixation of the stapes, 40% had incudostapedial joint defects followed by fixation of the malleus and/or incus and defects in the incudostapedial joint with a fixation of the stapes.1) One of the most common ossicular chain anomalies in Korea was a stapes footplate fixation (54.5%) followed by a mobile stapes footplate with other anomalies (19.7%) including a stapes without suprastructure and an incus long process, stapes without anterior crus and an incus long process.2) One of the most common ossicular chain anomalies is the absence of an incus with or without an intact stapes suprastructure. In incudostapedial deformed ears, ossiculoplasty is mandatory to restore the hearing process. Ossiculoplasty is also needed in cases with incus long process erosion with inflammation. As the most vulnerable ossicles, one report said that incus erosion is found in 80% of the chronic otitis media.3) Austin-Kartush classified ossicular chain disruptions into four categories after 1,151 operation on chronic otitis media. Group A ears with an intact malleus handle and a stapes suprastructure was found in 59.2% followed by group B ears with an intact malleus handle but an eroded stapes suprastructure group.4) In the group of a tympanic membrane and malleus preserved but a stapes suprastructure eroded, ossicular continuity can be restored between the stapes footplate and manubrium of the malleus with the method of malleus footplate assembly (MFA) using either the incus body or if the incus is unavailable, a biocompatible material such as hydroxyapatite (HA).5,6,7) Until now, MFA has proven to be the safe and effective way to restore hearings in such patients.8,9,10,11,12)Though successful results using MFA with either incus body or biocompatible material are reported world widely, there were a few reports on audiologic results after MFA ossiculoplasty in Korea. Authors reviewed our procedure and report hearing results of ossiculoplasty with MFA using either incus or HA. In this paper, a single-surgeon series of 32 MFA operations was analyzed. The cases were limited to autologous interposition grafts performed on Austin-Kartush group B ears in order to provide consistency within the analysis.
Subjects and Methods
Data collection A retrospective evaluation has been carried out on patients who underwent MFA ossiculoplasty between September 2001 and March 2010 in Seoul National University Hospital. A total of 55 patients with Austin-Kartush type B defect repaired with incus body or HA were identified. Of those, 20 were excluded due to a failure to recover operation records or a lack of no more than 1 year postoperative audiograms. Three patients who had undergone MFA with a homologous incus were excluded in order to provide consistency within the analysis. Finally, 32 cases were enrolled into the study. All procedures were conducted by a single surgeon. All data including previous operations, follow-up duration, age, sex, etiology, materials which were used in the operation, combined mastoidectomy, complications, and revision operations were analyzed. Eustachian tube function was analyzed according to the results of the Eustachian tube test. The status of the middle ear mucosa was described as either 'healthy' or 'inflamed' according to the operation records. Demographic data are presented in Table 1.
Analysis of audiologic data Preoperative and postoperative hearing results were evaluated according to the guidelines of the Committee on Hearing and Equilibrium of the American Academy of Otolaryngology-Head Neck Surgery Foundation13) an...
Background and Objectives: Absence of incus is one of the most common ossicular anomalies and also frequently found in chronic otitis media or chornic otitis media with cholesteatoma. Ossiculoplasty with malleus footplate assembly (MFA) can be an excellent option in the above situations. We reviewed our procedures and evaluated the hearing results of ossiculoplasty using the MFA.
Subjects and Methods: This study retrospectively reviews a series of 32 patients who underwent MFA ossiculoplasty between September 2001 and March 2010 in an academic tertiary referral center. The autologous incus or hydroxyapatite (HA) was used as materials for reconstruction.
Results: Thirteen of 32 patients (40.6%) had ossicular chain anomaly, 9 patients (28.1%) had congenital cholesteatoma and 8 patients (25.0%) had chronic otitis media with cholesteatoma and 2 patients (6.3%) had chronic otitis media. The patients with ossicular chain anomaly showed the greatest air-bone gap (ABG) closure. Overall, postoperative ABG was 17.7±11.7 dB at postoperative 6 months and 19.7±14.3 dB at postoperative 1 year, compared with preoperative ABG of 37.9±9.3 dB. There was no statistical difference of ABG at postoperative 12 months, 24 months between MFA using incus (n=17) and HA (n=15)(p=0.300, and p=0.563). There was no meaningful difference of postoperative ABG between the patients with combined mastoidectomy (n=10) and those without mastoidecmoy (n=22)(p=0.555). No extrusions occurred.
