UNIVERSITY OF CENTRAL MISSOURI Welch-Schmidt Center for Communication Disorders Audiologic Evaluation Report CLIENT: Dustin Banana DATE OF BIRTH: 10-21-96 CLINICIANS: Amy Arsenault and Christina Cearlock DATE OF EVALUATION: 2-5-01 HISTORY: Dustin Banana, a 4 year-old male, was seen at the Welch-Schmidt Center on February 5, 2001 for a follow-up hearing evaluation. The audiological exam on January 22, 2001 revealed sound field localization to his name at 25 dB HL and to music at 30 dB HL in the better ear. Attempts to get test results using headphones were unsuccessful. Warble tones, spondee toys, and “point to…” responses were also unsuccessful. Dustin had persistent nasal drainage and Mrs. Banana stated he was recovering from a cold beginning one week prior to the evaluation date. Middle ear function was within normal limits in the right ear. Middle ear testing of the left ear; however, revealed significant negative middle ear pressure. This might have been attributable to Dustin’s cold symptoms. Recommendations were made to return to the clinic for further testing, and hopefully Dustin would be less apprehensive. RESULTS: During today’s evaluation, impedance testing using the EarScan revealed a Type A tympanogram in the right ear and a Type B tympanogram in the left ear. Ipsilateral acoustic reflexes were absent at 1 kHz bilaterally and at 2 kHz in the left ear when screened at 105 dB SPL. Otoacoustic Emissions (OAE) were present at all frequencies in the right ear except for at about 750 Hz. OAEs were absent at all frequencies in the left ear except for around 3 and 4 kHz. Pure tone audiometry using drop block procedures revealed pure tone averages (PTA) of 10 dB HL, bilaterally. Speech reception thresholds (SRT) with point to spondee toys using monitored live voice through headphones were 15 dB HL in the right ear and 20 dB HL in the left ear. IMPRESSIONS: The results indicate Dustin is hearing within normal limits throughout all frequencies in his right ear with normal middle ear function. His left ear is within normal limits in most frequencies, with a mild loss at 500 and 4000 Hz. This could be attributable to his stiff middle ear system, which is compatible with fluid behind the eardrum. Present OAEs in the right ear suggest normal outer hair cell function in the cochlea at the frequencies tested. Absent OAEs in the left ear are consistent with the results of tympanometry. RECOMMENDATIONS: It is recommended that Dustin: 1) Return to the clinic for his speech and language diagnostic session on 2-12-01 at 8:00 am. 2) Have his middle ear function reevaluated on 2-12-01. ______________________________ Amy Arsenault Graduate Clinician _____________________________ Deborah Galley, M.S., CCC-A Clinical Supervisor _______________________________ Christina Cearlock Graduate Clinician February 5, 2001 Parent(s) of Dustin Banana P.O. Box 123 Concordia, MO 64020 Dear Parent(s), Enclosed are the results of Dustin's audiological evaluation performed on February 5, 2001 at our clinic. As we discussed after the evaluation, testing revealed hearing within normal limits throughout all the pitches and normal middle ear function in his right ear. His left ear is within normal limits at most pitches, with a mild hearing loss at 500 and 4000 Hz. This could attributable to his cold symptoms and his stiff middle ear system (consistent with fluid behind his eardrum). It is recommended Dustin: 1) Return to the clinic for his speech and language diagnostic session on 2-12-01 at 8:00 am. 2) Have his middle ear function reevaluated on 2-12-01 also. If Dustin complains of discomfort in his ears, please consult with your physician. Please feel free to contact the clinic at (660) 543-4993 if you have any questions or if we can be of any further assistance.
