OBJECTIVE: To evaluate nasal ventilation in patients with obstructive sleep apnea hypopnea syndrome (OSAHS) after nasal cavity ventilation expansion techniques by using acoustic rhinometry. METHOD: Thirty-eight patients with mild OSAHS and 17 patients with moderate OSAHS who were diagnosis by PSG were selected. The acoustic rhinometry and rhinomanometry were used to assess the nasal cavity volumes (NCV), nasal airway resistance (NR), nasal minimal cross-section area (NMCA) and distance of nasal minimal cross-section area from nostril (DCAN) before and after the surgery (6 month later). RESULT: The state of mild OSAHS group in NCV, NMCA and NR: before surgery (2.41 ± 1.33) cm³, (0.37 ± 0.39) cm², (2.07 ± 1.48) cmH₂O/(L · min), after surgery (2.53 ± 1.54) cm³, (0.45 ± 0.34) cm², (1.69 ± 1.03) cmH₂O/(L · min), has significant difference (P < 0.05). The state of moderate OSAHS group in NCV, NMCA and NR: before surgery (2.03 ± 1.54)cm³, (0.29 ± 0.39) cm², (3.47 ± 2.56) cmH₂O/(L · min), after surgery (2.31 ± 1.47) cm³, (0.39 ± 0.33) cm², (1.89 ± 1.03)cmH₂O/(L · min), also has significant difference (P < 0.05), while DCAN in two group had no difference (P > 0.05). CONCLUSION There was an objective evaluation of nasal ventilation in OSAHS patients after surgery by using acoustic rhinometry.

OBJECTIVE: Patients undergone septoplasty, which is one of the most common procedures, always feel very painful after surgery because of routine nasal packing. The objective of this study was to evaluate the effect of septal suture technique without nasal packing after septoplasty. METHOD: Eighty patients who had undergone septoplasty were included in this study. The patients were allocated into tow groups: packing group, mercel was used for nasal packing after septoplasty and inferior turbinate coblation; suturing group, septal suture and inferior turbinate coblation were performed after septoplasty without nasal packing. Postoperative signs and symptoms(visual analogue scale,VAS) were compared between the two groups. RESULT: The patients of packing group experienced significantly more postoperative nasal pain, headache, dysphagia, sleep disturbance and bleeding after surgery (P < 0.01). No difference of epiphora was found between the two groups. More pain and bleeding were experienced during the pack removal(packing group), compared to that during the clearance of nasal cavity (suturing group ). One patient with postoperative septal hematoma was found in the packing group. CONCLUSION Nasal septum suture combined with inferior turbinate coblation might be a significantly more comfortable, reliable alternative to nasal packing. Nasal packing is not the necessary application for septoplasty.

To review retrospectively six cases of rhino-orbital related endoscopic surgeries aided by Fusion electromagnetic system,to explore the indications and clinical value of image guided technique in endonasal endoscopic surgery.Retrospective research methods were used.In this study,six cases of nasal endoscopic sinus surgery using Fusion electromagnetic system were analyzed,including 1 nasal penetrating foreign body,2 optic nerve decompressions,1 orbital apex hemangioma,1 sieve frontal sinus cyst,1 intraorbital mass biopsy.The preparation time of navigation system,the accuracy of intraoperative positioning and surgical coherence,intraoperative and postoperative complications of surgery were recorded.The average preparation time was(8.13 ± 1.858)min.In the navigation,the sinus ostium,orbital cardboard,skull base,optic nerve,internal carotid artery and other important structures can be accurately located in all patients,while registrations had been accurate within 1 mm.Six patients were successfully operated by image guided technique.There was no intracranial or intraorbital complications due to intraoperation error.Image guided technique allows for a truely microinvasive and accurate rhino-orbital related endoscopic surgeries.It requires less preoperative preparation time,has high surgical navigation accuracy,improves the surgical coherence and safety,and reduces the surgical complicationgs.However,as an auxiliary tool,it can not replace the surgeon's anatomical knowledge,surgical training and clinical experience.

OBJECTIVETo study the airflow velocity, trace, distribution, pressure, as well as the airflow exchange between the nasal cavity and paranasal sinuses in a computer simulation of nasal cavity pre and post virtual endoscopic sinus surgery (ESS).

METHODSComputational fluid dynamics (CFD) technique was applied to construct an anatomically and proportionally accurate three-dimensional nasal model based on a healthy adult woman's nasal CT scans. A virtual ESS intervention was performed numerically on the normal nasal model using Fluent 6.1.22 software. Navier-Stokes and continuity equations were used to calculate and compare the airflow characteristics between pre and post ESS models.

RESULTS(1) After ESS flux in the common meatus decreased significantly. Flux in the middle meatus and the connected area of opened ethmoid sinus increased by 10% during stable inhalation and by 9% during exhalation. (2) Airflow velocity in the nasal sinus complex increased significantly after ESS. (3) After ESS airflow trace was significantly changed in the middle meatus. Wide-ranging vortices formed at the maxillary sinus, the connected area of ethmoid sinus and the sphenoid sinus. (4) Total nasal cavity resistance was decreased after ESS. (5) After ESS airflow exchange increased in the nasal sinuses, most markedly in the maxillary sinus.

CONCLUSIONSAfter ESS airflow velocity, flux and trace were altered. Airflow exchange increased in each nasal sinus, especially in the maxillary sinus.

OBJECTIVE: To explore curative effect with pedicle flap of nasal septum-basis nasi and temporal muscucofascial flap to repair nasal septal perforation. METHOD: Dissecting mucoperichondrium and mucoperioseptum around the perforation and taking dowm and out xia-ward to the floor of nasal cavity to make a inferior extremity pedicle flap. Then,the flap was tumbled and sutured onto raw surface of contralateral side through perforation. Reapplicating autoallergic temporal musculofascial flap to repair another side perforation. RESULT: Repairing perforation Sin twelve cases were sucessfully healed in endoscope. CONCLUSION The pedicle flap of nasal septum-basis nasi and temporal muscucofascial flap is easy to acquire and no rejection. The flap has good blood supplying, high survival rate and provides adequate transplantating materail to repair comparatively large perforation.
