    Olfactory function tests performed in clinical settings were reviewed. Olfactory function tests are classified by subjective and objective testing, however objective testing is not commonly used in the clinical setting, only subjective testing is performed. The subjective testing is divided into three components; threshold, identification, and discrimination testing. The T&T olfactometer is recognized as a standard olfactory test in Japan and measures both threshold and odor identification function. However, it is rarely used in clinical settings because of the complexity of testing and problems associated with ventilation and residual odors in the environment. Recently two new olfactory function tests have been developed and are available to measure odor identification ability, Odor Sticks and Open Essence. They are very effective methods for the assessment and identification of patients with olfactory dysfunction, however they cannot be used as a clinical test because insurance approval has not yet obtained. With clinical application of the objective testing, it is demanded in future that an examination for these identification testings comes to be used at a clinical place.

    We evaluated the postoperative audiological findings and perforation closure rate of in 164 ears of patients with perforated otitis media following tympanoplasty conducted via a retroauricular approach (underlay technique for myringoplasty) by the same operator. The results demonstrated a success rate of improved hearing of 90.2% and a tympanic membrane closure rate at more than one year after the surgery of as high as 92.1%. To assess the factors affecting the postoperative hearing improvement, logistic regression analysis was carried out. Ossicular reconstruction (Type III) and presence of tympanosclerosis were identified as statistically significant negative factors unfavorably affecting postoperative hearing improvement. The tympanic membrane perforation closure rate was higher in younger patients. There were no significant differences of the tympanic membrane perforation closure rate depending on the size of the perforation or the underlying disease.
    No correlation was observed between the operative experience and the audiological outcomes or perforation closure rate, suggesting that this operation may be relatively easy to master. Since the tympanic membrane closure rate was higher than that achieved by the adhesive technique and was comparable to that obtained using the overlay technique, it was considered that the underlay technique via a retroauricular approach may be an excellent choice for the first operation, because it causes less postoperative lateralization of the repaired tympanic membrane.

    Cholesterol granuloma is the most common disease of the petrous apex. We report a case of petrous-apex cholesterol granuloma who was treated by the endoscopic transsphenoidal approach. A 34-year male presented to another clinic with a history of otorrhea and dizziness; CT revealed a shadow in the petrous apex, and he was referred to our department.
    CT and MRI revealed that the lesion was adjacent to the sphenoid sinus, therefore, we attempted a transsphenoidal approach for endoscopy. We examined the cystic lesion by endoscopy and ruptured it. The brownish contents were discharged and the debris of the cyst was completely removed.
    As compared to other approaches, the transsphenoidal sinus approach is simple, with a relatively low risk of postoperative complications such as nerve damage, hearing loss and cerebrospinal fluid leakage. In addition to, surgery can be treated of distinct vision. Thus, the transsphenoidal approach may be selected as the preferred approach for lesions of the cone apex in the future.
