A Retroauricular Cholesteatoma in Soft Tissue after Tympanomastoidectomy / 대한이비인후과학회지

As a postoperative complication, the recurrence of aural cholesteatoma is well documented. On rare occasions, a recurred cholesteatoma can penetrate the adjacent soft tissues instead of middle ear or extemal auditory canal. Recently, authors experienced a cholesteatoma in soft tissues of posteriorinferior portion of auricle, developing 8 years after an intact bridge mastoidectomy. We reviewed the reported case of cholesteatoma in soft tissues.

Two Cases of Isolated Sphenoid Sinus Aspergillosis / 대한이비인후과학회지

Aspergillus sp. are the most common contaminants found in the paranasal fungal sinusitis, but isolated sphenoid sinus invasion is extremely rare. According to sinus anatomy and depending on its contiguous structures, various symptoms and complications may appear. Of these symptoms and complications, headaches are the most frequently observed in the few documented cases. The treatment is primarily surgical, through either transnasal or transethmoid approach, depending on whether or not the disease is limited to the sphenoid sinus. The transnasal endoscopic technique offers excellent visualization and an atraumatic approach to the sphenoid sinus. It is performed with the superior turbinate used as the key landmark for identification. For this technique, a wide enlargement of the natural sphenoid ostium is also important. Along with a review of literature, we present two cases of sphenoid sinus aspergillosis which were successfully treated by transnasal endoscopic sphenoidotomy.

A Case of Bilateral Chylothorax Following Neck Dissection without Chyle Leakage of Neck / 대한이비인후과학회지

A chylous fistula has been reported to occur in 1% to 2% of cases as a complication of neck dissections, but a bilateral chylothorax following neck dissection, without concurrent chylous leakage at operation site, was very rare. In the chylothorax, serious problems may occur in cardiopulmonary function, metabolism, and nutrition of patient. Early diagnosis and proper management is very important. Recently authors experienced a case of bilateral chylothorax following neck dissection and managed with conservative treatment.
