[Cartilage palisade tympanoplasty for adhesive otitis media].
OBJECTIVE
We evaluated the clinical utility of cartilage palisade tympanoplasty (CRPT) in adhesive otitis media, a condition known to recur frequently with poor success in hearing gain.


OBJECTIVE
Specimens were 9 ears having adhesive otitis media and undergoing CPT in January 2006 and December 2007. Cases of pars tensa cholesteatoma were excluded. Mean subject age was 35.2 years. Seven had total drum adhesion and 2 posterior half-adhesion. Preoperative pure-tone hearing averaged 20-102 dB (mean: 56 dB).


METHODS
A small piece of cartilage harvested from the cymba was obliquely sectioned to yield wide, thin cartilage strips. Strips were overlapped slightly anteriorly to posteriorly parallel to the malleus handle when present. Tympanoplasty type 1 was conducted in 2 cases, type 3c in 6, and type 4c in 1.


RESULTS
No ears undergoing CPT produced recurrent adhesion or perforation although 2 suffered transient partial erosion healed easily in topical management. An air-bone gap of <15 dB was achieved in 3 ears, a hearing gain exceeding 15 dB in 5, and a hearing level of less than 30 dB in 3. Conditions falling in at least 1 of the above categories are considered successful based on Japan Otological Society criteria. Seven of the 9 (78%) were regarded as audiologically successful.


CONCLUSIONS
CPT conducted for adhesive otitis media appears worthwhile, given the present better-than-expected results in our cases, although further study is needed to confirm this conclusion.
