In order to evaluate lymphatic metastasis to the supraretrospinal recess (SRSR) in laryngeal squamous cell carcinoma (SCC), we separately dissected SRSR lymph nodes and submitted them to pathological examination. Fifty-three lateral neck dissections (LNDs), 2 radical neck dissections (RNDs), and 19 modified RNDs were performed in 49 previously untreated patients with laryngeal SCC. The nodal status of the patients was N0 in 29 patients, N1 in 17, and N2 in 3. The neck was pathologically positive in both RNDs (100%), in 7 of 19 modified RNDs (37%), and in 7 of 53 LNDs (13%). No SRSR lymph nodes were positive in any of the dissection materials. No metastasis was found in the SRSR lymph nodes in the N0 necks treated with LND, and none was found even in N1 and N2 necks treated with RND or modified RND. We conclude that the SRSR may be left undissected during treatment of an N0 neck with LND so that accessory nerve dysfunction can be minimized and operative time can be saved.
Objective: Serotonergic neurons innervating motoneurons increase their firing rates in response to respiratory challenges, and long-term facilitation of respiratory activity in response to hypoxia is serotonin (5-HT) dependent. Polymorphism of the genes which code for 5-HT receptors may affect functions of the serotonergic system, and may be associated with obstructive sleep apnea syndrome (OSAS). The objective in this study was to assess the significance of T102C and –1438G/A polymorphisms of the 5-HT2A receptor gene in OSAS. Methods: Fifty-five patients with OSAS and 102 healthy volun teers were included for genetic analyses of T102C and –1438G/A polymorphisms of the 5-HT2A receptor gene. Results: For the T102C polymorphism, there was no significant difference between the patients and controls and both genders (p > 0.05). For the –1438G/A polymorphism, the A/A and G/A genotypes were overrepresented in the patients and controls, respectively (p = 0.045). In the control group, the genotypes of both genders were not significantly different (p > 0.05). In the patients, the A/A and G/A genotypes were overrepresented in males and females, respectively (p = 0.035). Concerning males, the A/A genotype was overrepresented in patients (p = 0.007). Conclusion: Serotonergic mechanisms appear to be related to OSAS. The T102C polymorphism of the 5-HT2A receptor gene is not associated with OSAS. However, the –1438G/A polymorphism is associated with OSAS occurrence, especially in male patients. This polymorphism may also be associated with different OSAS incidences of both genders.
Objective: MESNA is a synthetic sulfur compound that produces mucolysis by disrupting disulfide bonds. This study aimed to address indications and technique of MESNA application in otologic surgery, especially in retraction pockets and adhesive otitis media. Methods: MESNA application was performed in 42 ears of 39 patients. The diagnoses were retraction pockets fixed to incudostapedial joint, stapes or promontorium, and adhesive otitis media in 24 and 17 ears, respectively. Calculations were performed according to 24 ears of 23 patients with follow-up data. Results: One or more of the following surgical interventions were performed: MESNA application alone and ventilation tube insertion, reinforcement or mastoidectomy in addition to MESNA application. Sensorineural hearing loss was not encountered after MESNA application. The operation was successful in 79.2%. Overall revision surgery was needed in 20.8% of the ears. In 71.4% of the ears treated with MESNA alone, revision surgery was needed. Conclusion: In the light of our experience, we advocate the use of MESNA in atelectatic ears, because it makes the operation easy and safe by allowing elevation of the tympanic membrane by its mechanical and chemical actions.
This is a prospective randomized study conducted in a group of children who underwent two methods of tonsillectomy: thermal welding or cold knife tonsillectomy. Parameters, such as postoperative pain scores, intraoperative blood loss, operation time, and postoperative bleeding rates, were analyzed to find out which technique is better. Ninety-one children (aged between 2 years and 13 years) with recurrent tonsillitis, obstructive sleep apnea syndrome, or both were included in the study. According to the type of tonsillectomy procedure, the patients were divided into two groups: cold knife and thermal welding procedure. The two groups were compared on the basis of postoperative pain scores, intraoperative blood loss, operation time, and postoperative bleeding. Fifty-seven patients underwent thermal welding tonsillectomy and 34 had cold knife tonsillectomy. The mean pain score in thermal welding group was significantly lower (p<0.001). There was no remarkable blood loss intraoperatively in the thermal welding procedure. The operation time was not significantly different between two groups. No postoperative bleeding was encountered in the thermal welding group. Compared with the cold knife technique, thermal welding was found to be a relatively new and safe technique for tonsillectomy as it results in significantly less postoperative pain and no remarkable blood loss.
No surgery is free of complications varying from common minor problems to very unexpected and severe ones. In the case presented here, unilateral paralysis of the muscles of the tongue and ipsilateral vocal cord paralysis due to a lesion of the 10th and 12th cranial nerves occurred following a septorhinoplasty that was performed under endotracheal general anesthesia. This rare entity known as Tapia's Syndrome is believed to be caused by pressure neuropathy of both nerves due to inflation of the cuff within the larynx. We remind surgeons of this unusual complication that can occur in any surgery under general anesthesia and discuss its diagnosis, treatment method, and the followup results in light of the literature.
