Procedures in the latter group included antrotomy
in 13 patients, intact-canal-wall mastoidectomy in 5, intact-canal-wall mastoidectomy plus a lateral atticotomy in 4, and lateral atticotomy in 3.
In addition to demographic data and the type of prosthesis, we compiled information on pre- and postoperative audiometric findings, the underlying diagnosis, the timing of surgery (primary, planned, or revision), the type of surgery (tympanoplasty alone, tympanoplasty with antrotomy, intact-canal-wall tympanomastoidectomy, or canal-wall-down tympanomastoidectomy), the extent of reconstruction (partial or total), the use of the malleus, the use of a tragal cartilage graft, and evidence of extrusion.
1%), 12 patients underwent tympanoplasty with antrotomy (5.
The patient was transferred to our institution, where he underwent examination of both ears under anesthesia along with incision and drainage of the SPAs and transmastoid antrotomy
Four fresh cadaver heads were dissected through a sublabial antrotomy incision with a 30[degrees] endoscope attached to a flexible holder.
5-cm antrotomy was made with a 3-mm osteotome and mallet.
3) They used an endoscope for visualization via a sublabial antrotomy approach to aid in the external placement of titanium mesh.
5) They modified the technique described by Saunders et al (3) by making a larger antrotomy (2.
Note that for states that use the CPT coding system, counts include all procedures that involved a mastoidectomy, including complete mastoidectomy, modified radical mastoidectomy, radical mastoidectomy, transmastoid antrotomy
, petrous apicectomy including radical mastoidectomy, all revision mastoidectomy procedures, tympanoplasty with antrotomy
or mastoidectomy, tympanoplasty with mastoidectomy, mastoid obliteration, and labyrinthectomy with mastoidectomy.
