OBJECTIVE: To summarize the diagnostic and therapeutic experience of primary cricopharyngeal achalasia and introduce new operandi modus. METHOD: Report the two cases we treated in 2008 and integrate published literature, and approach its diagnostic and therapeutic experience and make use of new operandi modus. RESULT: The diagnosis of primary cricopharyngeal achalasia is difficult, and we must apply exclusive diagnosis according to the examinations of fibrolaryngoscopy, esophagoscopy and barium meal et al. CONCLUSION Surgical treatment is the best option. Partial resection of cricopharyngeal muscle and upper esophageal ring-shaped muscle is superior to simple cricopharyngeal myotomy.

OBJECTIVETo investigate the relationship between the changes of upper airway and genioglossus muscle activity after the treatment with Snoreguard.

METHODS31 patients with OSAS or snoring were treated with Snoreguard Cephalometric analysis was carried out to compare the changes of the upper airway before and after the treatment. The relationship between the change in morphology and that of genioglossus muscle activity among 22 patients was investigated.

RESULTS(1) The size of upper airway decreased significantly with Snoreguard. SPP-SPPW increased from (9.14 +/- 3.79) mm to (12.36 +/- 3.74) mm and TB-TPPW increased from (10.63 +/- 3.71) mm to (11.90 +/- 4.33) mm. UC-LC decreased from (21.96 +/- 11.06) mm to (10.48 +/- 8.55) mm and H-MP decreased from (20.60 +/- 6.65) mm to (11.01 +/- 6.84) mm. (2) The size of upper airway in part of the patients decreased with Snoreguard, but good treatment efficiency remained.

CONCLUSIONThe mechanism of Snoreguard is caused by the mechanical enlargement of upper airway.

OBJECTIVE: To discuss the effect of reducing the cricopharyngeal dysfunction on the Groningen prosthesis voice restoration following total laryngectomy and the effect of different methods. METHOD: Fifty-six patients were implanted with Groningen voice prostheses to rebuild voice after total laryngectomy. The clinical data were analyzed retrospectively. RESULT: Of 56 patients, 412 patients successes in voice restoration. The success rate of amputating pharynx plexus nerves group was 60.0%, amputating cricopharyngeal muscle group was 62.5%, and the amputating pharynx plexus nerves and cricopharyngeal muscle group was 96.0%. CONCLUSION The combination of pharynx plexus nerves resection and cricopharyngeal myotomy can make higher success rate of voice restoration.
