Outcomes of upper airway reconstructive surgery for obstructive sleep apnea syndrome based on polysomnography after nasopharyngeal tube insertion.

Background: The most common obstruction sites for obstructive sleep apnea hypopnea syndrome (OSAHS) are the oropharynx and the glossopharyx. The diagnosis of glossopharyngeal airway obstruction is difficult. The study aimed to assess the effect of upper airway reconstructive surgery for OSAHS based on polysomnography (PSG) after nasopharyngeal tube insertion (NPT-PSG), and to evaluate the clinical value of NPT-PSG in localizing the obstructive sites.

[Clinical observation on the origin of antrochoanal polyp].

Objective: To explore the origin and etiopathogenesis of antrochoanal polyp (ACP) based on the clinical data.

Methods: Twenty-six patients with ACP were included in the study. All the ACP patients were documented by preoperative endoscopy and computer tomographic (CT) scans.

[Treatment and prevention of serious perioperative complications of obstructive sleep apnea hypopnea syndrome].

Objective: To summarize experiences of serious perioperative complications management of obstructive sleep apnea hypopnea syndrome (OSAHS), and evaluate the effect of intervention in decreasing the incidence of serious complications.

Methods: Retrospective analysis of clinical data in Shenyang General Hospital of PLA and Liaoning Province Jinqiu Hospital of OSAHS surgery cases from January 1995 to December 2009 were included in this study, patients were divided into two groups according to with or without intervention. Experience and lessons were analyzed.

[Study of lingual arterial CT angiography and security of partial glossectomy in obstructive sleep apnea hypopnea syndrome].

Objective: To explore the difference of lingual arterial CT angiography images(CTA) between obstructive sleep apnea hypopnea syndrome (OSAHS) patients and normal subjects, and to investigate the safety of partial glossectomy guided by lingual arteria CT angiography.

Methods: Seventy-four patients with OSAHS and 10 control adults were included in the study. The lingual upper airway and lingual arterial CT angiography were obtained.

[Frontal sinusitis after transfrontal craniotomy: causes and management].

Objective: To explore the causes, clinical manifestation and therapy of frontal sinusitis after transfrontal craniotomy.

Methods: Thirty-three patients with frontal sinusitis after transfrontal craniotomy were included in the study. Among them, 7 cases had frontal sinus abscess and 4 cases had frontal sinus fistula.

[Relationship of lingual region upper airway stricture and lingua-palate position type in obstructive sleep apnea hypopnea syndrome patients].

Objective: To explore the relationship ol lingual region upper airway stricture and lingua-palate position type in obstructive sleep apnea hypopnea syndrome (OSAHS) patients.

Methods: One hundred patients with OSAHS were included in the study and divided into 4 groups by lingua-palate age, AHI, BMI and lowest SaO2, the dimensions and area of lingual region airway, the thickness of retropharyngeal and lateral pharyngeal tissue, the tongue width, tongue length and tongue area were compared among four groups. The multinomial step regression process was performed with SPSS software to explore the effects of lingua-palate position type on lingual region upper airway stricture.
