  • Title: Endoscope-assisted second-stage tympanomastoidectomy.
    Author: Youssef TF, Poe DS.
    Journal: Laryngoscope; 1997 Oct; 107(10):1341-4. PubMed ID: 9331310.
    Abstract:
    Intact canal wall mastoidectomy techniques for cholesteatoma are often followed by a planned second look for residual disease and possible ossicular reconstruction. Endoscopic techniques may reduce morbidity but introduce new concerns. Twenty-five consecutive second-look procedures were performed from July 1994 to July 1996 utilizing endoscopes in 19 cases and avoiding or terminating their use in the others because of known difficult anatomy, inadequate exposure, or excessive bleeding. Thirteen cases were prospectively explored first through a planned exclusively endoscopic approach and then opened for a conventional second look in comparison. In one of the 13 cases, endoscopy was abandoned. There were no cases in which endoscopy yielded a false-negative result. Endoscopes underestimated the size of recurrence in one case. Our experience, indications, and precautions for endoscope-assisted second-stage tympanomastoidectomy are presented.
