ABSTRACT

Stensen's duct is located at the anterior border of the parotid gland below the zygomatic arch. It crosses the area between the masseter muscle and buccal fat pad, opening opposite to the second upper molar teeth. Because of such anatomical association by the Stensen's duct, we should search for any injuries on the Stensen's duct when there is deep facial laceration. This paper reports on a case of parotid sialocele which was caused by laceration of Stensen's duct. For treamtemnt, we made an internal fistula to the oral cavity in order to drain the sialocele

ABSTRACT

BACKGROUND AND OBJECTIVES: The clinical utility of otoacoustic emissions (OAEs) has been well established in childhood hearing screenings. As middle ear negative pressure prevails in normal children, and since all OAEs must be transmitted through the middle ear before they can be measured in the ear canal, OAEs can be affected by middle ear negative pressure. The purpose of this study is to elucidate the effect of middle ear negative pressure on the detectability of OAEs. MATERIAL AND METHODS: TEOAEs were recorded for 36 ears using click before & after tonsillectomy and, or adenoidectomy (T and, or A) operations. Before & after T and or A operations, DPOAEs were generated at six geometric mean frequencies between 1-6 kHz for two different groups, Group I (40 ears) and Group II (36 ears). Group I: 3(f2/f1) ratios (1.21, 1.22 and 1.23) were used at the fixed stimulus level (70-70 dB SPL). Group II:3 stimulus levels were used (70-70 dB SPL, 60-70 dB SPL and 30-40 dB SPL). RESULTS: The negative middle ear pressure attenuated low frequency emission more than high frequency emission. CONCLUSION: Negative middle ear pressure may increase false alarm. So pneumatic otoscopy and aural immittance testing should be utilized to predict the feasibility of applying OAEs in childhood hearing screening test.

ABSTRACT

The goal of treatment in OME is normal aerated middle ear space. When the tympanogram convert to type A or C from type B in patients with OME, no further medication would be needed. But 1/3 of these patient had type B tympanogram again after 4 weeks follow up without medication. Many parameters-including age, sex, season, unilaterality, passive smoking, associated rhinitis etc-were concerned about the recurrence of OME. Ultra high frequency audiometry was added as a new parameter in recurrence of OME.
