As in this report, a polypectomy via an antrotomy may be feasible.
Via an antrotomy the pedunculated polyp measuring 4.5cm was resected (figure 2B).
B: Brunner's gland adenoma with stalk (broken arrow) arising from 1st part of duodenum delivered via antrotomy
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.
Of the entire study population, 129 patients underwent tympanoplasty alone (58.1%), 12 patients underwent tympanoplasty with antrotomy (5.4%), 66 patients underwent intact-canal-wall tympanomastoidectomy (29.7%), and 15 patients underwent canal-wall-down tympanomastoidectomy (6.8%).
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
. No myringotomy was performed in view of the presence of spontaneous drainage.
Four fresh cadaver heads were dissected through a sublabial antrotomy incision with a 30[degrees] endoscope attached to a flexible holder.
An approximate 2.0 x 1.5-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 (2.0 x 1.5 cm) for the transantral placement of orbital implants (Medpor or titanium mesh).
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.
