Therapeutic effects of oral appliance combined with uvulopalatopharyngoplasty on obstructive sleep apnea hypopnea syndrome / 中华口腔医学杂志

<p><b>OBJECTIVE</b>To explore the long-term effects of the uvulopalatopharyngoplasty (UPPP) combined with oral appliance (OA) in the treatment of obstructive sleep apnea hypopnea syndrome (OSAHS).</p><p><b>METHODS</b>Thirty patients with severe OSAHS confirmed by polysomnography (PSG) according to their apnea hypopnea index (AHI) and lowest SaO2 during sleep were selected using random permutation table and divided into only UPPP group(U group, n = 15) and UPPP with OA group (UA group, n = 15). The follow-up period was 2 years. PSG was performed in 0.5 year and 2 years after operation. AHI, lowest SaO2 and Tmax were tested and evaluated.</p><p><b>RESULTS</b>The effectiveness of two groups was the same after 0.5 year. Two years after operation, the values [AHI: (18.06 ± 2.24) times/h; lowest SaO2: (88.64 ± 10.37)% and Tmax: (20.5 ± 17.6) s] in UA group were better than that [AHI: (49.73 ± 3.35) times/h; lowest SaO2: (79.56 ± 4.87)% and Tmax: (41.3 ± 19.7) s] in U group. The number of effectiveness was 9 and the number of ineffectiveness was 6 in U group, while in UA group, the number of effectiveness was 14 and the number of ineffectiveness was 1(P < 0.05).</p><p><b>CONCLUSIONS</b>Long-term result of combined treatment was better than that of UPPP only.</p>

Transnasal endoscopic marsupialization for treatment of maxillary cysts / 临床耳鼻咽喉头颈外科杂志

OBJECTIVE@#To evaluate the effectiveness and usefulness of transnasal endoscopic surgery for the treatment of maxillary cysts.@*METHOD@#Transnasal endoscopic surgery was performed in 13 patients with maxillary cysts that extended to the maxillary sinus or the nasal bottom. Five patients had a radicular cyst, three patients had a dentigerous cyst, three patients had a nasolabial cyst and two patients had a median cyst. After the resection of anterior edge of the inferior turbinate or the nasal bottom, the lateral wall of the inferior nasal meatus was opened. Then, the cyst wall of the maxillary sinus was partially or completely removed under the endoscope.@*RESULT@#The cyst walls were completely or partial removed in 13 patients with maxillary cysts. There were no complications, and postoperative courses were uneventful. The follow-up period ranged from 6 to 36 months, and no recurrence were noted in any of the cases.@*CONCLUSION@#Endoscopic transnasal surgery for the maxillary cyst is less invasive than conventional dental approach, and most of the affected teeth can be preserved. This technique appears to be a simple and highly effective surgical treatment for the treatment of patients with maxillary cysts that extend to the maxillary sinus or the nasal bottom.
