[Audiological and Otological Status of 45 Infants with Cleft Palate].

Objective: To study the audiological and otological status of cleft palate infants with the application of distortion product otoacoustic emission (DPOAE), auditory brainstem response (ABR), tympanometry with 1000 Hz and 226 Hz probe tones.

Methods: Totally 45 cleft palate infants aged 8-24 months were included in the study. Most of them were examined for DPOAE, ABR and two frequency tympanometry.

Oncocytic carcinoma of the parotid gland.

Objectives/hypothesis: The incidence of oncocytic carcinoma of the parotid gland is low, so a systematic evaluation of treatment strategies is lacking. We aimed to describe our experiences in treating this malignancy.

Study Design: Retrospective study.

[A clinicopathologic study on oncocytoma and oncocytic carcinoma of the salivary glands].

Objective: To investigate the clinicopathologic features, differential diagnosis, treatment and prognosis of oncocytoma and oncocytic carcinoma of the salivary glands.

Methods: The clinicopathologic features were studied in 23 cases of oncocytomas and 15 cases of oncocytic carcinomas, and immunohistochemical staining as well as electron microscopy were performed.

Results: Most oncocytomas occurred in the parotid gland (95.

Primary oncocytic carcinoma of the salivary glands: a clinicopathologic and immunohistochemical study of 12 cases.

Oncocytic carcinoma (OC) of salivary gland origin is an extremely rare proliferation of malignant oncocytes with adenocarcinomatous architectural phenotypes, including infiltrative qualities. To help clarify the clinicopathologic and prognostic features of this tumor group, herein, we report 12 OC cases arising from the salivary glands, together with follow-up data and immunohistochemical observations. There were 10 males and 2 females with an age range of 41 to 86 years (median age: 61.
