ABSTRACT

OBJECTIVE: In this study, we investigated the effects of desflurane 6%, on olfactory memory. PATIENTS AND METHODS: This is a prospective clinical study performed with 40 patients aged 18-60 who had elective surgery and American Society of Anesthesiologists (ASA) physical status I-III. The Brief Smell Identification Test (BSIT) was used for evaluating patients' olfactory memories before and after the surgery. Patients received standard general anesthesia protocol and routine monitoring. For induction, 1.5 mg/kg of fentanyl, 2 mg/kg of propofol, and 0.5 mg/kg of rocuronium bromide were administered. Anesthesia was maintained with the inhalational of anesthetic desflurane (6%). The scores are recorded 30 minutes before the surgery and when the Aldrete Recovery Score reached 10 in the postoperative period. Preoperative and postoperative results were compared and p-values <0.05 were considered statistically significant. RESULTS: The patients' mean age was 41.1±12.0. Preoperative total correct answer rate to odorous substances was 92.7%, and postoperative rate was 92.1%. Percentage of the odor substance identification by the patients revealed no statistically significant difference when pre and post-operative rates have been compared (p-value >0.05). CONCLUSIONS: We have observed for the first time in the literature that general anesthesia using desflurane (6%) did not affect short-term olfactory memory. Further studies will be necessary to confirm our findings with larger sample size.

ABSTRACT

PURPOSE: The aim of this study is to evaluate our approach to patients with squamous cell carcinoma of lower lip. PATIENTS AND METHODS: This study includes 31 lower lip squamous cell carcinomas followed up between 1994 and 2000. Primary treatment was applied to 28 patients of whom 23 were in stages I-II and five in stages III-IV. Three patients presented locoregional recurrence. Neck dissection was performed during primary lip resection in patients with palpable cervical lymph node involvement. Patients with unpalpable cervical lymph nodes were divided into two subgroups: one was submitted to elective neck dissection (n = 11) and the other had isolated lip resection (n = 8). Unilateral or bilateral selective supra-omohyoid neck dissection (SOHND) was performed according to the localisation of the disease. Radical dissection was performed in a secondary intervention, when SOHND revealed lymph node metastases. Radiotherapy and chemotherapy were applied for curative and/or adjuvant treatment in addition to surgery in patients with locoregional recurrence and metastatic lymph nodes or with perineural involvement. RESULTS: Occult cervical metastasis within a single lymph node was found in one of the 11 No patients who underwent elective neck dissection. Delayed neck metastasis developed in one of the eight patients in whom isolated lip resection (without neck exploration) was performed. Chemoradiotherapy was administered to this patient, but he died. Neck metastasis was established histologically in four of five patients in stages III-IV. Postoperative radiotherapy was used on these patients. One of the patients in this group died due to inoperable local recurrence in the neck, another died because of distant metastasis. Local mandibular recurrence was seen in one of these patients after three years. COMMENT: Six patients (19%) died due to lower lip carcinoma in this series. Our findings show the importance of elective neck dissection and intact surgical resection margins.
