ABSTRACT
BACKGROUND AND OBJECTIVES: To determine the anatomic position of the inferior alveolar nerve (IAN) canal in patients with mandibular prognathism using the cone-beam CT (CBCT). MATERIALS AND METHODS: Fifty rami from 25 patients were evaluated. The images were taken by i-CAT and reconstructed 3-dimensionally using the Simplant 11 program. The linear distances between the IAN canal to the buccal cortex (a, a* and a**), from the IAN canal to the alveolar crest (b and b*) and the anterior margin (b**) and finally the buccal cortical thickness (c, c* and c**) were measured at three reference planes (VP, OP and HP). RESULTS: On the left side, the average distance of a, b and c were 7.12, 15.96 and 3.60 mm on the VP plane, respectively. On the OP, the distance of a*, b* and c* was 6.11, 8.83 and 2.63 mm. For the HP, the distance of a**, b** and c** was 4.84, 10.11 and 2.30 mm. On the right side, the distance of a, b and c, on the VP, was 7.10, 16.13 and 3.42 mm, respectively. On the OP, the distance of a*, b* and c* was 4.77, 8.75 and 2.68 mm. On the HP, the distance of a*, b* and c** was 4.55, 9.84 and 2.38 mm. Regarding the difference between genders, the distance in male's was longer than female's on the VP (p=0.019), and was thicker in males than females on the HP (p=0.002). CONCLUSION: The CBCT data provided accurate information about the location and course of the IAN.

Basaloid squamous cell carcinoma (BSCC) is uncommon and distinct variant of squamous cell carcinoma that arises mostly in the upper aerodigestive tract and aggressive, high grade tumor with an increased tendency to be deeply invasive, multifocal, and metastatic even at the initial presentation. The typical microscopic features of carcinoma with a basaloid pattern in intimate association with a squamous component helps in diagnosis of this tumour. Since Wain's report in 1986, BSCC of oral cavity, the palate, floor of the mouth, nasopharynx, oropharynx and mastoid region have been reported. However, BSCC in the nasal cavity or in the paranasal sinuses is rare and there are few reports in the Korean literature. We had experienced a case of basaloid squamous cell carcinoma that occurred in the left maxillary sinus of 72-year-old woman and reported with review of the clinical and pathologic features from the literature.

Background: Post operative nausea, vomiting and pain are the most common distressing symptoms following surgery. Recently much interest has been shown in the influence of auditory stimuli during anesthesia, and studies suggest that thinking may occur while under adequate general anesthesia. The aim of my study was to investigate the effect of intraoperative positive suggestion on the incidence of post operative pain, nausea, vomiting, general well being and gas output time. METHODS: Following ethics committee approval of our hospital, informed written consent was obtained from 60 ASA 1 or 2 patients scheduled for major gynecological surgery. Patients were allocated randomly to study or control groups. Those in the study group were played tapes containing positive suggestions ; those in control group were played a blank tape. Anesthesia was induced with propofol, succinycholine, vecuronium, and was maintained with enflurane 1.5 vol% in a 50% mixture of oxygen in nitrous oxide. Head phones were applied and patients in study group were played a tape suggesting that there would be no pain, nausea or vomiting and that they would be comfortable after the operation. The tape was played repeatedly throughout surgery until skin closure. The severity of postoperative nausea, vomiting, pain, postpoerative well being state and gas output were assessed using a four-point 0-3 verbal rating score (VRS) and scores were collected in the recovery room, at a postoperative 3 hr, 6 hr, 12 hr, 24 hr and 5 days. RESULTS: There was no significant difference between groups for any VRS parameter, i.e., postoperative pain, nausea, vomiting, general state of being or gas output time. CONCLUSIONS: Despite hearing positive suggestion in patients undergoing total hysterectomy surgery during general anesthesia, we were unable to demonstrate any reduction in the incidence of postoperative pain, nausea, vomiting, general well being state scores and gas output time.
