Parent Cognitive Satisfaction and Demand Research of Neonatal Hearing Screening.

The primary aim of the present study was to investigate parent cognitive satisfaction and demand by using a valid and reliable questionnaire developed for this purpose (Parent Cognitive Satisfaction and Demand Questionnaire with Neonatal Hearing Screening Program, PCSDQ-NHSP). About 1000 parents whose children received hearing screening participated in this study. The satisfaction questionnaire was found to be a useful instrument for identifying service shortfalls, and the routine use of the PCSDQ-NHSP in other neonatal hearing screening programs is recommended.

Autologous meatal skin graft implantation and intratympanic injection of Pseudomonas aeruginosa: a new experimental mouse model of acquired middle ear cholesteatoma.

Aim: To create an experimental model for the biomedical research of middle ear cholesteatoma.

Methods: Cholesteatoma was induced in the right ears of mice. An autologous meatal skin graft was implanted into the middle ear via the tympanic membrane followed by an intratympanic injection of Pseudomonas aeruginosa.

[Clinical significance of intact canal wall mastoidectomy combined with facial recess opening in the treatment of secretory otitis media of children].

Objective: To investigate the clinical significance of intact canal wall mastoidectomy combined with facial recess opening in the treatment of secretory otitis media of children.

Methods: The clinical data of 17 children (19 ears) with recurrent secretory otitis media yet failed tube insertion more than 3 times, and treated with intact canal wall mastoidectomy combined with facial recess opening, in the Department of Otorhinolaryngology Head and Neck Surgery, Second Affiliated Hospital of SUN Yat-sen University, were reviewed. And because of the eustachian tube dysfunction, 7 ears simultaneously accepted tube insertion, which were removed after 1 to 3 months.

[Long-term therapeutic effects of repairing the whole auricular defects with osseointegrated prosthetic ears].

Objective: To evaluate the long-term therapeutic effects of repairing the whole auricular defects with osseointegrated prosthetic ears.

Methods: From January 2002 to December 2005, 62 patients (63 ears) with the whole auricular defects were treated with osseointegrated prosthetic ears and followed up for 5 - 8 years (median 6.5 years) after operations.
