Application of the Mimic Valsalva Maneuver with the Help of a Saccule in Cerebrospinal Fluid Rhinorrhea Reconstruction Surgery.

Objective: To explore the mimic Valsalva maneuver with the help of a saccule handled by an anesthesiologist in order to locate the leakage channel and repair the fistula during intranasal endoscopic reconstruction surgery of cerebrospinal fluid rhinorrhea.

Methods: From 2012 to 2014, 8 patients were diagnosed with cerebrospinal fluid rhinorrhea by medical histories, physical and biochemical examination. All patients were treated with intranasal endoscopic reconstruction surgery of cerebrospinal fluid rhinorrhea.

[Clinical research of transoral endoscopic adenoidectomy on the treatment of the adenoid hypertrophy children with chronic sinusitis].

Objective: To determine the clinical value of transoral endoscopic adenoidectomy for the pediatric sinusitis.

Method: Patients with chronic sinusitis and adenoid hypertrophy were divided into two group by undertaken with or without adenoidectomy, the operation group with 43 cases and the control group with 40 cases. Evaluation was performed in pretherapy and after 3 months therapy.

[Clinical research of 24-hour double-probe pH-metry in the laryngopharyngeal reflux diseases].

Objective: To determine the clinical value of 24 h double-probe pH-metry for the diagnosis and treatment of laryngopharyngeal reflux (LPR).

Methods: According to the pH-metry results (whether the reflux events record in the upper esophagus is more than 6.9), patients of refractory pharyngolaryngitis were divided into LPR and control groups (each of 17 cases).

[Effects of hyperbilirubinemia on distortion product otoacoustic emission, auditory brainstem response and mismatch negativity in guinea pigs].

Objective: To explore the characteristics of distortion product otoacoustic emission (DPOAE), auditory brainstem response (ABR) and mismatch negativity (MMN) in guinea pigs with hyperbilirubinemia and assess the impact of hyperbilirubinemia on their hearing functions.

Method: Normal neonatal guinea pigs were randomly divided into normal control, low- and high-dose bilirubin groups. DPOAE, ABR and MMN were tested and compared between the 3 groups of guinea pigs.

[Comparative study of pure tone stimuli and Chinese speech stimuli on auditory event-related potentials].

Objective: To compare the characteristics of auditory event-related potentials (AERP) evoked by pure tone stimuli and Chinese speech stimuli respectively, and to explore the feasibility of using Chinese speech stimuli to evoke AERP for Chinese.

Methods: AERP were tested by both Chinese speech and pure tone as stimuli in normal young participants (83 ears in 44 young postgraduate students), then each AERP wave form were scored. The latencies, amplitudes and scores of AERP evoked by speech stimuli were compared with by pure tone stimuli.

[Effect of stimulus intensity on auditory event-related potentials evoked by tone and speech].

Objective: To explore the effect of stimulus intensity on auditory event-related potentials (AERP) evoked by tone stimuli and speech stimuli respectively.

Method: Normal young participants were tested by both tone and speech stimulus with different intensity levels. Range of the intensity for the typical AERP to tone stimuli and speech stimuli were compared.
