  • Abstract
  • Look Inside

The epidermization difficulty of postopera-tive mastoid wound, the author believes, may be divided into 2 types of pathological entity as causative factors: 1) Due to dermatitis, 2) Due to absorption of the transplanted skin-flap by forces of regenerating mastoid cells beneath.

The author shows the dermatitis to be that of erosive and desquamatous types. The for-mer might be caused by bacterial or mycotic infection while, the latter seemed to be the product of incomplete cholesteatoma forma-tion and occurred in cases where deep lying cavity was covered by a skin-flap.

These problems of postoperative complica-tions are seemed unavoidable in disposal of cases of well-developed mastoid structures. For treatment of these conditions, the author recommends reconstruction of the mastoid cavity for its preservation by using pedicle temporal muscle and periostium flap to form the posterior wall of the external auditory meatus.

The author emphasizes that, in case the mastoid cavity is opened during the process of performing tympanoplasty for treatment of chronic otitis media, the mastoid cavity should also be reconstructed. However, in treatment of chronic otitis media of mucositis type, the mastoid cavity is not routinely opened.
