The difference between delayed extubation and tracheostomy in post-operative sleep apnea after glossectomy or laryngectomy.
(1/24)
BACKGROUND: Patients with cancer of the tongue or larynx require glossectomies or laryngectomies and subsequent reconstruction. These procedures remove part of the patient's upper airway. In cancer of the tongue, the removed part of the airway is substituted by a flap of their skin. Post-operatively, it is possible that the patients have problems respiring comfortably. In addition to this, long surgical procedures may simply interfere with their circadian rhythm. To elucidate the possible change in their post-operative respiration, we monitored the patient's respiratory pattern with an apnea monitor. METHODS: We attached an apnea monitor to the patients and recorded their respiratory pattern and arterial oxygen saturation. The patients were monitored for a total of five days: three days prior to the operation, one day before the operation, the day of operation, two days after, and on the fourth day after the operation. The period of monitoring was from 8:00 p.m. to 6:00 a.m. the next morning. RESULTS: Sixteen patients completed this study. The patients whose tube was extubated after glossectomy showed frequent apnea, low mean oxygen saturation and low comfort score as compared to the patients with tracheostomy after laryngectomy. Because two failed cases of free skin flap were among the former, it is possible that the frequent apnea is a factor of failed free skin graft after glossectomy and laryngectomy. CONCLUSION: Further studies are required to improve the patient's respiration during their sleep after tracheal extubation in glossectomy. (+info)
Intraoperative spasm of coronary and peripheral artery--a case occurring after tourniquet deflation during sevoflurane anesthesia.
(2/24)
A 68-yr-old man with a 9-yr history of hypertension presented for hemiglossectomy, segmental resection of the mandible, and the radial forearm free flap grafting. Intraoperatively, facial artery spasm was observed during microvascular suturing of the radial artery to the facial artery. Simultaneously, systolic blood pressure decreased from 100 to 80 torr and the ST segment elevated to 15 mm from the base line. The possible mechanisms responsible for vasospasm in coronary as well as in peripheral arteries under sevoflurane anesthesia are discussed. (+info)
Masticatory efficiency before and after surgery in oral cancer patients: comparative study of glossectomy, marginal mandibulectomy and segmental mandibulectomy.
(3/24)
This study evaluated the effect of oral cancer surgery on masticatory efficiency. Masticatory efficiency was measured using the ATP absorption method. Eating ability was measured using a questionnaire. Two groups were employed as controls: The "normal occlusion group" consisted of subjects who had a complete set of natural maxillary teeth opposed to mandibular teeth, and the "unilateral occlusion group" consisted of subjects who had lost their molar and premolar teeth on one side of the mandible as a result of caries or periodontal diseases. Three treatment groups, each of 6 patients, were studied: a glossectomy group, a marginal mandibulectomy group and a segmental mandibulectomy group. There were no differences in masticatory efficiency between two control groups. Masticatory efficiencies of the three oral cancer treatment groups were lower than in the unilateral occlusion group, even 12 months after surgery. Masticatory efficiency of the glossectomy group was significantly higher 12 months after surgery compared with pre-surgery. Masticatory and eating abilities of the marginal mandibulectomy group and the segmental mandibulectomy were reduced at 3 and 6 months after surgery. The masticatory efficiency 12 months after surgery was higher in the marginal mandibulectomy group than the segmental mandibulectomy group, although the difference was not statistically significant. The self assessed eating ability 12 months after surgery was significantly higher in the marginal mandibulectomy group than the segmental mandibulectomy group. These results suggest that discontinuation of the mandible may lead patients to eat only foods that do not require a substantial amount of chewing. Hence, the quality of life of patients in the marginal mandibulectomy group was considered to be better than that in the segmental mandibulectomy group. (+info)
Group A beta-hemolytic streptococcal glossal necrotizing myositis--case report and review.
(4/24)
We report the first case of glossal necrotizing myositis by group A beta-hemolytic Streptococcus in an 8-year-old girl on chronic nonsteroidal anti-inflammatory drugs, immunomodulators, and steroids for juvenile rheumatoid arthritis. Treatment included partial glossectomy and parenteral antibiotics. After a critical course, full recovery ensued. The subject of necrotizing myositis is reviewed. (+info)
Is glossectomy necessary for late nodal metastases without clinical local recurrence after initial brachytherapy for N0 tongue cancer? A retrospective experience in 111 patients who received salvage therapy for cervical failure.
(5/24)
PURPOSE: To assess the efficacy of neck dissection (ND) without glossectomy (GL) for late nodal metastases without local recurrence after brachytherapy for N0 tongue cancer. MATERIALS AND METHODS: Among 396 patients with N0 tongue cancer treated with brachytherapy, a retrospective analysis was performed in 111 patients who were clinically diagnosed as having nodal metastases without local recurrence and whose neck lymph nodes turned out to be pathologically positive after salvage surgery. One hundred and five patients had undergone only ND (the ND group), six patients had undergone ND with GL (the ND+GL group). RESULTS: The 5 year disease-free and cause-specific survival rates after salvage therapy for the 111 patients included in this study were 58.1 and 61.9%, respectively. In the ND group, there were only nine patients who had local recurrence after ND. In addition, only six patients (5.7%) had a local recurrence within 2 years in the ND group. Sixty-three patients were free of disease after ND, 31 patients had regional or distant metastases without local recurrence and two patients had progressive disease at ND. In the ND+GL group, four patients were alive without disease and two died from regional or distant metastases. None of the patients in the ND+GL group were found to have malignant tissue in the pathological findings from the excised tongue. CONCLUSION: GL should be avoided or suspended when the clinical evaluation had revealed cervical failure without apparent local recurrence in the mobile tongue cancer patients after initial brachytherapy.

Effect of mandibular nerve block on postoperative analgesia in patients undergoing oropharyngeal carcinoma surgery under general anaesthesia.
(6/24)
BACKGROUND: Postoperative analgesia after oropharyngeal carcinoma surgery remains poorly studied. This study investigates the effects of mandibular nerve block (MNB) with ropivacaine 10 mg ml(-1) in conjunction with general anaesthesia (GA) on postoperative analgesia after partial glossectomy or transmandibular lateral pharyngectomy. METHODS: In a randomized double-blind study, 42 patients (21 in each group) received an MNB by the lateral extra-oral approach (MNB group) or a deep s.c. injection of normal saline (control group). Both groups received a standardized general anaesthetic. Postoperative analgesia included fixed dose of i.v. acetaminophen and morphine via a patient-controlled analgesia device. Consumption of morphine and supplemental analgesics and pain scores at rest were measured. RESULTS: The mean cumulative morphine consumption was reduced by 56 and 45% at 12 and 24 h after operation in the MNB group. The administration of analgesic rescue medications was delayed in the MNB group. The visual analogue scale (VAS) pain scores were comparable in the two groups during the first 24 h. Adequate analgesia (mean VAS < or = 3) was observed throughout the study period in the MNB group, but only from 4 h after operation onwards in the control group. The number of patients who experienced severe pain (VAS > 7) during the first postoperative day was lower in the MNB group than in the control group (3 vs 10. respectively, P < 0.05). CONCLUSIONS: In this study, MNB performed before GA for oropharyngeal carcinoma surgery improved postoperative analgesia, resulting in reduced morphine consumption at 24 h and severe pain in fewer patients.

Simultaneous off-pump coronary artery bypass graft surgery and wide glossectomy.
(7/24)
Patients suffering with significant coronary artery disease undergoing elective noncardiac surgery may benefit by revascularisation prior to noncardiac surgery with high or intermediate risks. Alternatively, combined procedures can be performed. We describe the management of an anaesthetic patient suffering with significant coronary artery disease with left ventricular dysfunction and tumour of the tongue causing difficult intubation.
