OBJECTIVETo evaluate three-axis otoconia maneuver (TOM) for benign paroxysmal positional vertigo (BPPV).

METHODSThe data from twenty BPPV patients who received three-axis otoconia maneuver treatment and 20 BPPV patients who received canalith repositioning (CRP) maneuver treatment were analyzed retrospectively.

RESULTSThere were 17 patients received 1 TOM session and 3 patients received 2 TOM sessions while 16 patients received 1 CRP session and 4 patients received 2 CRP sessions. The chi-square (X2) test was used in evaluating the association between two independent samples in a contingency table. Both methods had no statistically significant. The significance level for statistical tests was 5% (alpha = 0.05).

CONCLUSIONSThree-axis otoconia maneuver could be effective used in benign paroxysmal positional vertigo with the advantage of repeatedly practicable and instrumental.

OBJECTIVETo compare the clinical benefits of rapid Rhino Stammberger sinus dressing (RR), a new nasal packing material for functional endoscopic sinus surgery (ESS), with traditional packing materials sorbalgon plus Vaseline gauze (SV) prospectively.

METHODSTwenty-four patients with chronic sinusitis of the similar grade were enrolled in the study. After ESS, the nasal cavities of each patient were packed with RR in the right side as observing group and SV in the left side as control group. SV in the left nasal cavity was removed in the first day after operation and RR remained in the right nasal cavity until the first endoscopic follow-up 1 week postoperatively. The same perioperative treatments such as irrigation and local steroid were given in both sides of nasal cavities. The grade of rhinalgia, nasal obstruction, discharge, bleeding and epiphora in each side of nasal cavities were assessed on a visual analogue scale (VAS) by the patients at the operation day (packing period), the first day and the second day after operation respectively. Postoperative endoscopic assessment of nasal cavities including crust, discharge, pseudomembrane, edema of mucosa, bubble and ostium obstruction were carried out by a rhinologist on VAS at 1, 2, 3, 4, 6, 8 weeks postoperatively. The follow-up continued until the complete mucosal healing.

RESULTSThree patients were dropped from statistical analysis. One of them with severe hypertension bleeding when he awoke from anesthesia, the RR was run out from the nasal cavity. The other two were lost in the follow-up. Twenty-one patients completed the follow -up ranging between 2-20 months. The scores of rhinalgia, epiphora at the operation day and the rhinalgia at the first day after operation in RR side were lower than SV side (P<0.05). The scores of the amount of crust at the first week after operation in RR side were lower than SV side (P<0.05). Statistically, no significant deference was found between RR and SV in the length of mucosal healing period.

CONCLUSIONSPatients felt more comfortable with the package of RR than traditional material. No pain and secondary bleeding happened. The efficacy of RR on mucosal healing was similar with SV. RR showed some advantages and could be used as packing material following ESS.

OBJECTIVETo establish the deep cervical lymph node metastasis model of tongue VX2 carcinoma in rabbits and to observe its metastatic features.

METHODSThe VX2 carcinomas were transplanted into the left ventral submucosa of tongues of 16 rabbits by injecting carcinoma mass suspension. According to the time the rabbits were killed after the transplantation of VX2 carcinoma, they were divided into four groups, or 7-, 14-, 21- and 28-day groups, and 4 rabbits in each group. The specimens of transplanted tongue carcinomas and cervical lymph nodes in the rabbits were examined histopathologically after they were killed.

RESULTSAll rabbits developed VX2 tongue carcinomas at the transplanted sites, which were confirmed with pathological examination, and the mean diameters of tongue carcinomas of 7-, 14-, 21- and 28-day groups were (0.74 +/- 0.06) cm (average +/- s), (1.62 +/- 0.06) cm, (1.82 +/- 0.04) cm and (2.52 +/- 0.07) cm respectively. No cervical lymph node was palpable at bilateral necks in each rabbit of 7-, 14- and 21-day groups, and only 4 rabbits of 28-day group had palpable lymph nodes at ipsilateral necks. The histopathological examination revealed no lymph node metastasis in the rabbits of 7-day group. Ipsilateral deep cervical lymph node metastases were confirmed histopathologically in each rabbit of 14-, 21- and 28-day groups, which located beside larynx-trachea. Two of 4 rabbits in 28-day group occurred bilateral deep cervical lymph node metastases. The mean diameters of the ipsilateral deep cervical lymph nodes of 7-, 14-, 21- and 28-day groups were (0.52 +/- 0.03) cm, (0.78 +/- 0.04) cm, (0.82 +/- 0.03) cm and (1.42 +/- 0.08) cm respectively. No metastasis from the transplanted tongue carcinomas was found in superficial cervical lymph nodes and submandibular lymph nodes in all rabbits.

CONCLUSIONSThe deep cervical lymph node metastasis develops at 2 weeks after the transplantation of tongue VX2 carcinoma and a deep cervical lymph node metastasis model of tongue VX2 carcinoma can be established.
