“…It is known that the Palva flap undergoes some degree of atrophy after surgery, but the recovery of the wound is quicker than the inferiorly based flap or the superiorly based flap because of sufficient blood supply and the nerve connection from the posterior segment of the facial nerve. 13,15 We got the proper mastoid obliteration without using additional material other than modified Palva flap. There was no need for additional autogenous material harvesting for the reconstruction of the posterior EAC wall.…”

Objective: To evaluate the effectiveness of a modified Palva flap used for external auditory canal reconstruction and mastoid obliteration in canal wall down mastoidectomy. Methods: We retrospectively analyzed patients who underwent canal wall down mastoidectomy with tympanoplasty using modified Palva flap. All patients underwent pure tone audiometry and temporal bone computed tomography (CT) before surgery, and the same tests were performed in the first year after surgery. The external auditory canal volumes were calculated by summing the areas of each section selected in temporal bone CT. For each patient, the ratio of external auditory canal volume was calculated from CT taken before and after surgery. Results: The mean of external auditory canal volume after canal wall down with a modified Palva flap was about 1.4 times larger than before surgery. The modified Palva flap is effective for the reconstruction of the external auditory canal. Both pure tone audiometry level and air-bone gap showed statistically significant improvement after surgery ( Ps = .001 and .002, respectively). Conclusions: The external auditory canal volume slightly increased, but the status of mastoid obliteration was well maintained 1 year after surgery. The modified Palva flap used in this study is an easy and effective method in external auditory canal reconstruction and mastoid obliteration.

“…We were especially interested in the stability of the obliteration material that was used. The musculoperiosteal flap atrophies postoperatively, but it often leaves a smooth lining for the cavity [ 15 ]. Reconstructed canal walls and reconstructed epitympanic cavities tend to enlarge postoperatively [ 2 ].…”

“…A 7-year follow-up of the reconstructed ear canals showed that the ear canal has a tendency to enlarge due to the atrophy of the musculoperiosteal flap [ 15 , 16 ]. Our results show that the difference of the volume between the operated and unoperated ears is significant.…”

“…One of the pioneers who described obliteration of the cavity was Mosher (Mosher, 1911). Palva reported in the 1960s the use of an anteriorly pedicled postauricular musculoperiostal flap (Palva et al, 1968;Palva et al, 1972). To prevent entrance of water and bacteria, the external meatus can be closed as well.…”

Patients who, despite treatment, suffer persistent chronic otitis media (COM), a radical cavity and a hearing loss of more than 55 decibels for more than five years, can be classified as having an ‘endstage’ COM. It is generally agreed that retained infected residual cell tracts or a too small meatus are common causes for failure of surgery for COM. Radical revision mastoidectomy (RRM) aims to remove all residual cell tracts in the mastoid, in the middle-ear cleft, around the labyrinth and around the Eustachian tube. The mastoid cavity is obliterated with a pedicled muscle flap. Thus the mastoid cavity is reduced and selfcleansing is improved. The first 16 consecutive patients who underwent a RRM for ‘endstage’ COM were included in this study. In about 80 per cent the treatment resulted in a dry ear. We, therefore, conclude that RRM is an effective and safe method for treating ‘endstage’ COM.
