[Relationship between obstructive sleep apnea-hypopnea syndrome and hypertension].

Objective: To explore the relationship between obstructive sleep apnea-hypopnea syndrome (OSAHS) and hypertension.

Methods: There were 1149 middle aged patients who were suspected to have OSAHS underwent polysomnography (PSG) from Jan, 1999 to June, 2011. The age of the patients ranged from 45 to 65 years.

[Electronic laryngoscope for transnasal esophageal examination].

Objective: To evaluate the value of electronic laryngoscope for transnasal esophagoscopy.

Methods: The electronic laryngoscope was used for transnasal esophagoscopy in 50 patients from June 2009 to June 2011 in our department. There were 32 males and 18 females with their age ranged from 16-88 years (mean 53.

[Reliability and validity of the simplified Chinese version of Epworth sleepiness scale].

Objective: To investigate the reliability and validity of the simplified Chinese version of Epworth sleepiness scale(ESS).

Methods: Five hundred and eighty-five patients with suspected obstructive sleep apnea hypopnea syndrome (OSAHS) and 103 OSAHS patients who underwent operations were included in this study. The ESS was filled before polysomnography (PSG) monitoring under the direction of professional technicians.

[Design of standard voice sample text for subjective auditory perceptual evaluation of voice disorders].

Objective: To design a speech voice sample text with all phonemes in Mandarin for subjective auditory perceptual evaluation of voice disorders.

Methods: The principles for design of a speech voice sample text are: The short text should include the 21 initials and 39 finals, this may cover all the phonemes in Mandarin. Also, the short text should have some meanings.

[Intraoperative facial nerve monitoring in parotid gland surgery].

Objective: To re-evaluate the value and the methods of intraoperative facial nerve monitoring in parotid gland surgery.

Methods: Sixty-five cases received intraoperative facial nerve monitoring in parotidectomy (test group) since 2000 - 2008. The facial nerve was identified through central trunk method (n = 18), branch method (n = 35) and mixed method (n = 12).

[Clinical shapes of vocal cord polyps and their pathological features].

Objective: To observe the clinical shapes of vocal cord polyps and their pathological features.

Methods: The laryngoscopic photographs of 156 patients with vocal cord polyps were reviewed. All patients received phonomicrosurgery.

[Value of Epworth sleepiness scale in assessment the degree of sleep disordered breathing].

Objective: To study the value of Epworth sleepiness scale in assessment of obstructive sleep apnea hypopnea syndrome (OSAHS) severity.

Methods: The polysomnography (PSG) data of 620 suspected OSAHS patients from Jan. 2000 to Dec.

[Varices of the vocal cord: report of 21 cases].

Objective: To study the diagnosis and treatment of varices of the vocal cord.

Methods: The clinical data of 21 cases with varix of vocal cord were analyzed. All the patients presented hoarseness.

[Clinical value of TS90% in evaluation of hypoxemia in patients with obstructive sleep apnea/hypoventilation syndrome].

Objective: To explore the appropriate study how to properly evaluate the hypoxemia degree in patients with obstructive sleep apnea/hypoventilation syndrome (OSAHS).

Methods: polysomnography was conducted on 108 OSAHS patients and 37 simple snorers to record the minimum oxygen saturation level (MiO(2)) and the total recorded time spent below 90% oxygen saturation (TS90%). The correlation between MiO(2) and the percent of the total recorded time spent below 90% oxygen saturation (TS90%) with the AHI were calculated.
