OBJECTIVETo investigate the efficacy and safety of nebulizing glucocorticoid combined with olfactory training in the treatment of postviral olfactory dysfunction.METHODSPatients with postviral olfactory dysfunction were recruited in this study. All patients underwent T&T olfactory testing, sinonasal computer tomgraphy scanning, as well as magnetic resonance scanning of the olfactory pathway. Nebulizing glucocorticoid (pulmicort repulse) was inhaled once daily at the starting dose of 2 mg tapered to 1 mg after two weeks combined with olfactory training for 4 weeks. T&T olfactory testing were repeated after 4-week treatment.RESULTS Twenty four patients received teatment, with a mean age of 54 years old(range 37 to 81 years old), a mean olfactory dysfunction course of 2.20 months(range, 0.25-9 months). Of whom, 21 were anosmia, 3 were hyposmia. After teatment, complete recovery were achieved in 4 patients(16.7%), obvious improvement in 9 (37.5%), improvement in 5 (20.8%), no improvement in 6 (25.0%). No side effect and untoward effect were found.CONCLUSIONThe primmary outcomes suggest the efficacy and safety of nebulizing glucocorticoid combined with olfactory training in the treatment of postviral olfactory dysfunction.

OBJECTIVETo explore the application of immediate recurrent laryngeal nerve reconstruction in the treatment of thyroid cancer invading the recurrent laryngeal nerve.
METHODSTen patients with thyroid cancer invading unilateral recurrent laryngeal nerve underwent radical surgery and immediate recurrent laryngeal nerve reconstruction. The reconstructive surgical approach included recurrent laryngeal nerve decompression surgery, end-to-end anastomosis of the recurrent laryngeal nerve, anastomosis of ansa cervicalis nerve to the recurrent laryngeal nerve, and nerve-muscle pedicle (NMP) technique. Among the ten patients, one underwent nerve decompression, one underwent end-to-end anastomosis of the recurrent laryngeal nerve, seven had anastomosis of ansa cervicalis to recurrent laryngeal nerve, and one case had anastomosis of ansa cervicalis to recurrent laryngeal nerve combined with nerve-muscle pedicle (NMP) technique. The effect of surgery was evaluated by videolaryngoscopy, maximum phonation time (MPT), phonation efficiency index (PEI) and voice assessment. T-test was used in the statistical analysis.
RESULTSAll of the 10 patients had no complications including tumor recurrence and hypoparathyroidism after the surgery. Their hoarseness symptoms were improved, and the patients returned to normal or near-normal voice. Postoperative videolaryngoscopy showed that paralyzed vocal cord returned to normal muscle tone and volume, and the vocal cord vibration and mucosal wave were symmetric and the patients got good glottal closure. The pre- and post-operative maximum phone times of the patients were (4.52 ± 0.89) s and (11.91 ± 1.87) s, respectively (P < 0.01). The pre- and post-operative phonation efficiency indices were (1.37 ± 0.43) s/L and (4.02 ± 1.33) s/L, respectively (P < 0.05).
CONCLUSIONSIn patients with thyroid cancer invading unilateral recurrent laryngeal nerve, immediate recurrent laryngeal nerve reconstruction following radical surgery of thyroid cancer can effectively achieve recovery in phonation function and improve the quality of life of the patients.

OBJECTIVE:
In-depth understanding of endoscopic anatomy of the skull base is the cornerstone of the development of endoscopic endonasal skull base surgery. The purpose of this study is to explore the anatomical landmarks of the clivus for endoscopic endonasal skull base surgery.
METHOD:
Eight silicon-injected adult cadaveric heads (16 sides) were dissected performing endoscopic endonasal approach. The clivus and adjacent structures were exposed; and their anatomy shown in detail. High-quality pictures were produced.
RESULT:
The clivus was subdivided into the upper, the middle and the lower clivus. Extracranial soft tissue landmarks and bony landmarks were presented. Intradural landmarks of the upper clivus were the interpeduncular cistern, posterior cerebral artery, posterior communicating artery, superior cerebellar artery, cranial nerve III and cerebral peduncle; intradural landmarks of the middle clivus were the prepontine cistern, basilar artery, cranial nerve VI and pons; intradural landmarks of lower clivus were premedullary cistern, vertebral artery, cranial nerve XI and medulla oblongata. Surgical routes to the clivus were the upper clivus approach, middle clivus approach, lower clivus approach and panclival approach.
CONCLUSION
An understanding of the complex anatomy of the clivus is paramount for surgically dealing with the disease involved clivus and adjacent region.

OBJECTIVE:
To evaluate the etiology and management of delayed epistaxis after endoscopic surgery.
METHOD:
To retrospectively analyze the clinical data of 11 cases for epistaxis after nasal endoscopic surgery. To compare their precipitating factors, their surgical approach, time and site of bleeding and management in order to find the intrinsic rules.
RESULT:
The precipitating factors, bleeding sites and treatments varied among patients.
CONCLUSION
Delayed epistaxis after endoscopic surgery can not be neglected. There may be some precipitating factors. The surgical approach may be related to the bleeding site. It is better to treat the epistaxis using the endoscope to explore the bleeding site and to give corresponding intervention.

OBJECTIVE:
To describe a modified lateral pharyngoplasty with partial transsection of levator veli palatine muscle in patients with obstructive sleep apnea hypopnea syndrome (OSAHS) and report the primary outcomes.
METHOD:
Retrospective review was performed in sixty patients with OSAHS. All the patients underwent modified surgical procedures, including partial transsection of levator veli palatine muscle and high soft palatoplasty.
RESULT:
The patients with a reduction of the AHI at least 50% were 6 (6/60, 10%). The patients with a reduction of the AHI at least 50% and a postoperative AHI < 20 were 44 (44/60, 73.3%). The patients with a postoperative AHI < 5 were 10 (10/60, 16.7%). Postoperative complications were postoperative bleeding in two cases (3.3%) and short-term velopharyngeal insufficiency in 10 cases (16.7%).
CONCLUSION
Lateral pharyngoplasty with partial transsection of levator veli palatine muscle provides a safe and effective procedure for selected OSAHS patients with oropharyngeal collapse as the main site.

OBJECTIVE:
To investigate the application of mitomycin in laryngeal surgery.
METHOD:
Retrospective analysis of the clinical data of 48 patients who had vocal cord lesion involving anterior commissure. The treatment of 30 patients treated with microsurgery and external application of mitomycin, while that of the others were only done with microsurgery.
RESULT:
Among the 30 patients who were treated with microsurgery and mitomycin, only 2 patients of which showed slight adhesion of anterior commissure after surgery. While in the group of microsurgery, there were 6 patients who had adhesion of anterior commissure adhesion after surgery.
CONCLUSION
Mitomycin could prevent vocal adhesion after laryngeal surgery.

Journal of Clinical Otorhinolaryngology Head and Neck Surgery 2009;23(12):549-552
OBJECTIVE:
To explore the feasibility, option of surgical method and surgery opportunity of local flap reconstruction in nasal defects due to severe infection after rhinoplasty.
METHOD:
The clinical datum of eleven patients, who had 15 cases of local flap reconstruction due to severe infection after rhinoplasty, were analyzed retrospectively. The lesions included defects of nasal dorsum, nasal tip and anterior-nare-vestibular fistula. Areas of defects ranged from 1.5 cm x 1.2 cm to 2.0 cm x 2.5 cm and fistula diameters fell between 0.6 cm and 0.9 cm. Based on the principal of nasal aesthetic sub-unit, nasal defects were restored with local flaps, such as nasal dorsum flaps, rhomboid flaps and nasal columella-tip flaps. The early changes and the maintenances of nasal contour after reconstruction were observed.
RESULT:
All 15 reconstructions were carried out 2 weeks after control of infection, and stage-I recovery was achieved in all the cases. In the follow-up periods from 4 to 27 months, all the flaps survived. only 2 cases had distortion of nasal tips, however, they were recovered with subcutaneous injection restoration; the other cases received satisfactory nasal contour where the flaps matched well with the neighbor skin in color, texture and extent of actinic dermatitis.
CONCLUSION
Based on the principal of nasal aesthetic sub-unit, the individualized early local flap reconstruction would have good effect on nasal function and aesthetics, which will restore self-confidence of the patients as soon as possible.
