RESUMO

PURPOSE: The type and extent of surgery for benign parotid tumors are a subject of debate. We aimed to measure and compare hospital stay, operative time, and complication rates associated with superficial parotidectomy (SP) and partial superficial parotidectomy (PSP). MATERIALS AND METHODS: This retrospective cohort study included all patients who underwent surgery for benign parotid gland tumors in our tertiary center between January 2006 and March 2014 and were followed up for at least 3 years. The predictor variable was the type of parotidectomy, and the main outcome parameters were operative time, hospital stay, and postoperative complications. The demographic characteristics (age and gender), clinical history, and preoperative findings were obtained from patient records. The Kolmogorov-Smirnov test, Mann-Whitney U test, and χ2 test were used to analyze the data. P < .05 was considered statistically significant. RESULTS: The sample was composed of 321 patients (184 men and 137 women) with a mean age of 54.0 ± 14.7 years (range, 18 to 87 years). Of these, 190 underwent SP and 131 underwent PSP. Pleomorphic adenoma was the most common tumor (83 patients, 53%), followed by Warthin tumor (50 patients, 32%). The mean hospital stay was 6.7 ± 2.3 days in the SP group and 4.8 ± 2.4 days in the PSP group (P < .001). The mean operative times in the SP and PSP groups were 134.0 ± 24.6 and 92.1 ± 21.9 minutes, respectively (P < .001). The overall complication rates were 21.6% and 12.2% in the SP and PSP groups, respectively (P = .031). No tumor recurrence was observed in either group. CONCLUSIONS: Compared with the SP group, the PSP group had shorter operative and hospital stay durations and fewer postoperative complications with a comparable recurrence rate. Therefore, PSP should be considered in suitable cases.

RESUMO

OBJECTIVE: We investigated the value of lymph node density (LND) as a predictor of survival in patients with laryngeal squamous cell carcinoma (SCC) and positive neck node (pN+) after laryngectomy. STUDY DESIGN: Case series with chart review. SETTING: Katip Celebi University Ataturk Training and Research Hospital, Izmir, Turkey. SUBJECTS AND METHODS: We reviewed the records of 289 patients with newly diagnosed primary laryngeal carcinomas who underwent partial or total laryngectomy and combined neck dissection at a tertiary referral center between June 2006 and December 2014. Patients with pN+ laryngeal SCC (n = 101) were included in the study. Overall survival (OS) and disease-free survival (DFS) were used to evaluate the prognostic significance of LND. RESULTS: In 101 patients with pN+ laryngeal SCC, LND ≥0.09 and number of metastatic lymph nodes >4 were significantly associated with OS and DFS but not the overall tumor, node, and metastasis stage. Forward stepwise Cox regression analysis revealed that LND ≥0.09 was the only independent predictor of both DFS and OS. Furthermore, the odds ratio of LND ≥0.09 was 10 times higher in patients with regional recurrence when compared patients without regional recurrence. CONCLUSIONS: LND was the only independent prognostic predictor of OS and DFS in patients with pN+ laryngeal SCC. Moreover, patients with LND ≥0.09 were significantly associated with high risk of regional recurrence. Thus, patients with LND ≥0.09 are at high risk of regional recurrence and death and may be considered for adjuvant chemoradiation.

RESUMO

OBJECTIVES: To present retrospective experience in Meyer-Cotton grade 3 tracheal stenosis of 17 patients treated by T-tube, considering the characteristics of the treated stenosis, surgical procedures performed, and post-operative outcomes and complications. METHODS: All demographic and clinical data were collected retrospectively. Chest and neck computed tomography scans were performed to assess the stenosis, including length, location, and glottic involvement. The stenotic area was evaluated endoscopically according to an adapted Meyer and Cotton grading scale. RESULTS: The aetiology of the tracheal stenosis was intubation-related in all cases. The duration of intubation ranged between 1 hour to 40 days. According to the Myers-Cotton classification, all patients were at stage 3. Mean length of the stenosis was 26.58 ± 12.02 (range =15-70) mm. Mean follow-up for the study group was 60.16 ± 34.10 (range =18-137) months. Two patients died during follow-up, one due to stroke, one due to chronic lymphocytic leukemia; no deaths were attributable to TS. The remaining 15 patients could be evaluated up to the present time. Post-operative decannulation was achieved in three of 15 patients (20%), and decannulation was not achieved in 12 of 15 patients (80%). CONCLUSION: T-tube is not an effective treatment of tracheal stenosis.

RESUMO

The aim of our study was to present our retrospective experience in the single-stage surgical reconstruction of 21 tracheal stenosis (TS) patients during the last 17 years, considering the characteristics of the treated stenosis, surgical procedures performed, and postoperative outcomes and complications. All demographic and clinical data were collected retrospectively. Chest and neck computed tomography (CT) scans were performed to assess the stenosis, including length, location, and glottic involvement. The stenotic area was evaluated endoscopically according to an adapted Myer and Cotton grading scale. The aetiology of the (TS) was intubation related in 18 patients and idiopathic in three patients. The duration of intubation was 13.00 ±â€Š6.83 days (range, 1 hour to 27 days). According to the Myers-Cotton classification, mean stage of stenosis for the study group was 3.33 ±â€Š0.66 (range, 2-4). Mean length of the stenosis was 2.05 ±â€Š0.80 (range, 1-3.5) cm. The mean number of stenotic segment involved was 3.67 ±â€Š1.24 (range, 2-6). Mean follow-up for the study group, excluding two patients who died in the postoperative period, was 57 (range, 12-326) months. Of the 19 patients who survived, postoperative decannulation was achieved in 16 patients (76.19%), and decannulation was not achieved in 3 patients (14.29%) who are still on a T-tube. Of the 16 patients who are decannulated successfully, additional procedures were applied in 9 patients. Segmental resection with primary anastomosis is an effective method and can be used as the first option in selected patients of (TS).

RESUMO

A 44-year-old man developed a slow-growing painless left superolateral orbital mass that extended into the frontal sinus with a complaint of ptosis. Magnetic resonance imaging revealed a heterogenous hyperintense lesion confined to the left frontal bone and superior orbit. The osteoplastic frontal sinus approach was performed to drain supraorbital cholesterol granuloma cyst and for curetting the capsule. Orbitofrontal cholesterol granuloma characteristically arises in the diploe of the superolateral frontal bone. The traditional approach for a primarily orbitofrontal cholesterol granuloma is the transorbital approach including anterior orbitotomy or lateral orbitotomy. However, the osteoplastic approach should be kept in mind as an alternative aprroach for the management of supraorbital lesions in patients with well-pneumatized frontal sinus.

RESUMO

OBJECTIVE: This study evaluated the diagnostic value of magnetic resonance imaging (MRI) and computed tomography (CT) in prevertebral space invasion in patients with head and neck squamous cell carcinomas (HNSCC). SUBJECTS AND METHODS: This study retrospectively reviewed 197 patients with advanced primary laryngeal or hypopharyngeal carcinoma who underwent laryngectomy and neck dissection at our institution. The MRI and CT findings were compared with the surgical findings and postoperative pathology. RESULTS: In 191 patients, the macro- and microscopic margins of the surgical specimens were tumor-free. In the remaining 6 patients, prevertebral space involvement was observed intraoperatively. MRI predicted the absence of prevertebral fascia invasion in 40 of 42 patients with a negative predictive value of 100% and specificity of 95.2%, while the negative predictive value and specificity of CT were 99.2% and 88.2%, respectively. CONCLUSION: Preservation of the retropharyngeal fat plane on MRI reliably predicts the absence of prevertebral space fixation in patients with advanced HNSCC.

RESUMO

AIM: The aims of this study were to compare radiofrequency tissue reduction (RFTR) and electrocautery (EC) techniques by assessing preoperatively and 8 weeks postoperatively the visual analog scale (VAS), inspiratory peak flowmetry (IPF), and magnetic resonance imaging (MRI) volume measurement of the inferior turbinate and to see whether EC still stands as a valid treatment of inferior turbinate hypertrophy. METHODS: A total of 36 patients were included in the study. An equal number of patients were chosen randomly from 2 groups. Inferior turbinate volumes measured by MRI, IPF, the VAS, and the Sinonasal Outcome Test-20 were used to determine the efficacy of treatment and to compare the 2 groups. RESULTS: Postoperative IPF increase, VAS score decrease, and Sinonasal Outcome Test-20 score decrease were statistically more significant in the EC group, compared with the RFTR group. Although statistically not significant, postoperative inferior turbinate MRI volume decrease was more evident in the EC group when compared with the RFTR group. CONCLUSIONS: Both RFTR and EC techniques could be used as an effective treatment of choice for inferior turbinate hypertrophy, and EC technique is superior to RFTR technique to achieve high efficiency.

RESUMO

The aim of our study was to determine the effectiveness of intratympanic α-lipoic acid injection as an otoprotective agent against cisplatin-induced ototoxicity in guinea pigs. Twenty-four adult male albino guinea pigs with normal hearing were divided into 4 groups. The guinea pigs received intraperitoneal cisplatin in group 1, intraperitoneal cisplatin and intratympanic α-lipoic acid in group 2, intratympanic α-lipoic acid in group 3, as well as intraperitoneal cisplatin and intratympanic saline in group 4. Distortion-product otoacoustic emission measurements were obtained for both ears at the following time points: before administration (baseline recording) and on day 3 (72 h later). In group 1 (cisplatin), significant deterioration was observed at all frequencies on day 3 (P < 0.05). In group 2 (cisplatin + α-lipoic acid), deterioration was observed at all frequencies on day 3; however, this deterioration did not reach a statistical significance (P > 0.05). In group 3 (α-lipoic acid), no significant difference was observed between baseline and day 3 (P > 0.05). In group 4 (cisplatin + saline), deterioration was observed at all frequencies on day 3; however, this deterioration did not reach a statistical significance (P > 0.05). Cisplatin-induced hearing loss in the guinea pigs may be limited to some extent by the concomitant use of α-lipoic acid. Dose-dependent changes in the possible effects of α-lipoic acid need further investigation. Future morphologic studies may contribute to expose clearly the protective effect of α-lipoic acid.

RESUMO

The external ear is composed of the auricle (pinna) and the external auditory canal. Both of these structures contain elastic cartilage (except the earlobe) and a small amount of subcutaneous fat, which are covered by skin. The skin of the cartilaginous canal contains hair cells, sebaceous (lipid-producing) glands, and apocrine (ceruminous) glands; this is in contrast with the osseous canal, which contains neither glands nor hair follicles. The auricle is susceptible to environmental influences and trauma. Due to its exposed locale, the ear is particularly vulnerable to the effects of ultraviolet light and, consequently, to preneoplastic and neoplastic skin lesions. The ear also has a sound-receiving function and a location that is both visible and aesthetically obvious, thereby drawing considerable attention from the patient. Dermatologic diseases on the external ear are seen in a variety of medical disciplines. Dermatologists, otorhinolaryngologists, family practitioners, and general and plastic surgeons are regularly consulted about cutaneous lesions on the ear. These lesions can be grouped into three main categories: (1) infectious; (2) tumoral; and (3) noninfectious inflammatory. The purposes of this contribution are to review various dermatologic diseases of the external ear and to update current diagnosis and treatment information related to these conditions.

RESUMO

CONCLUSIONS: Vocal and ventricular fold lateralization using crossing sutures with the thyroplasty window technique is an effective and durable procedure for the management of patients with bilateral vocal fold immobility. OBJECTIVES: To review the long-term results of bilateral vocal fold immobility in 26 patients treated with vocal and ventricular fold lateralization using crossing sutures with the thyroplasty window technique over a 6-year period. METHODS: This retrospective study examined patients with a minimum follow-up of 1 year. The main outcome measures used were the modified Medical Research Council (MRC) dyspnoea scale and the assessment of voice quality pre- and postoperatively using the Likert method. RESULTS: The mean follow-up period was 23.77 ± 12.01 months. All patients reported marked symptomatic improvement in dyspnoea (p = 0.0001). The voice quality worsened as expected; however, this difference did not reach a significant level (p = 0.642). Transient microaspiration was noted in seven of the patients and resolved in 1 or 2 days. The procedure was performed for the contralateral vocal fold in one case, due to the loss of suture tension. No patient showed aspiration postoperatively or during follow-up. All patients were regularly followed up for the beginning of movement of the lateralized or contralateral vocal folds in our outpatient clinic.

RESUMO

OBJECTIVE: This study evaluated the outcome in adult patients with laryngotracheal stenosis (LTS) and assessed the effect of procedures on their quality-of-life scores. METHODS: The study included 15 adult patients with LTS (11 males [73.3%], 4 females [26.7%]; mean age, 32 years [range, 10-52 years]) treated at the Department of Otolaryngology Head and Surgery Clinic, Izmir Atatürk Research Hospital, Turkey, from 1997 to 2008. Success of the surgery is evaluated by decanullation rate, Short form-36 (SF-36), and the Medical Research Council dyspnea scale. RESULTS: The etiology of the LTS was intubation related in 14 cases (93.3%) and idiopathic in 1 case. According to the Myers-Cotton classification, 2 (13%), 8 (54%), and 5 (33%) patients were at stages 2 to 4, respectively. Fourteen patients had a mean follow-up of 57 months (range, 24-256 months). The stenotic segment involved 1 to 3 cm (mean, 1.7 cm) of trachea, and 2 to 5 tracheal rings (mean, 3.1) were resected. Postoperative decannulation was achieved in 13 patients (86.6%). In the short form-36 questionnaire, all of the parameters except for "role-emotional" were found to be significant (P < 0.01). The Medical Research Council dyspnea scale assessment revealed a significant (P < 0.001) decrease postoperatively. CONCLUSIONS: Segmental resection with primary anastomosis is an effective method and can be used as the first option in selected cases of advanced stenosis.

RESUMO

OBJECTIVE: To investigate the ototoxic effect of boric acid solution prepared with different degree of alcohol. METHODS: This study was performed on 28 young albino guinea pigs. After the animals divided four groups prior to the application of the solution an auditory brainstem response (ABR) test was applied to the each animal under general anesthesia. Their tympanic membranes perforated and test solutions were administrated to the middle ear through the perforation. On 15th day, ABR measurements were carried out and comparison was made with preadministration values. RESULTS: The degrees of hearing loss occurring as a result of the administration of 4% boric alcohol solutions prepared with 60° and 40° alcohol differed significantly (p < 0.001). CONCLUSION: It was established that 4% boric acid solution prepared with 60 alcohol affected hearing in guinea pigs more negatively and an increase in degree of alcohol also increased the ototoxicity of the boric acid solution.

RESUMO

OBJECTIVE: The purpose of this study was to compare the efficacy of systemic steroid alone and combined with intratympanic methylprednisolone in the treatment of patients with idiopathic sudden sensorineural hearing loss. STUDY DESIGN: Prospective, randomized controlled trial. Settings Katip Celebi University Ataturk Training and Research Hospital, Izmir, Turkey. SUBJECT AND METHODS: Seventy-nine patients who met the inclusion criteria for idiopathic sudden sensorineural hearing loss were included in this study. Patients were randomly divided into 2 groups according to treatment: group A received combination therapy (intratympanic methylprednisolone + oral steroid) and group B received oral steroid alone. Of the 79 patients included, 6 patients missed the 1-month follow-up visit. Overall, 73 patients (37 combination group, 36 oral steroid group) who completed the 1-month follow-up and study intervention were included in the per-protocol analysis. Both the relationship between certain prognostic factors and the clinical outcome after treatment were analyzed. RESULTS: Combination therapy showed significant hearing improvement and speech discrimination scores compared with the use of systemic steroids alone (P < .05). In hearing outcomes in patients with severe hearing loss, combination therapy had statistically significant hearing improvement compared with oral steroid alone (P < .05). CONCLUSION: We recommend that combination therapy can be considered as initial treatment especially for patients with severe hearing loss.

RESUMO

OBJECTIVES: This study aims to evaluate the complications of tracheoesophageal puncture (TEP) for voice restoration and speech valves in patients undergoing total laryngectomy. PATIENTS AND METHODS: Between January 2006 and June 2011, 47 male patients (mean age 62.8±1.2 years; range 41 to 80 years) who underwent TEP and speech valve for voice restoration after total laryngectomy were retrospectively analyzed. Secondary TEP was performed and Provox indwelling voice prosthesis were inserted in all patients. Demographic, disease and treatment characteristics of patients were recorded. Complications related to TEP and speech valves, the management of complications and clinical conditions of complete closure of TEP were also recorded. RESULTS: Tracheoesophageal puncture and speech valve related complications were observed in 20 patients. The majority of complications were minor complications including granulation tissue formation (n=2, 4.2%), deglutition of prosthesis (n=6, 12.7%) and TEP enlargement/leakage around prosthesis (n=9, 19.1%). Major complications were observed in three patients. Two of them were life-threatening complications; a mediastinitis (n=1, 3.1%) and paraesophageal abscess (n=1, 3.1%), and both appeared in the first month of the postoperative period. The overall complication rate was 42.6% during mean follow-up of 15.3 months. Tracheoesophageal fistula enlargement (n=9, 19.1%) was the most common minor complication and the most common cause of complete closure of TEP in this study. CONCLUSION: Tracheoesophageal puncture for voice restoration is not an entirely innocent procedure without any complications. Patients should be monitored for TEP-related complications in the early and late postoperative period.

RESUMO

Synovial sarcomas (SS) account for 7-8% of soft-tissue cancers and 3-5% of all cases with head and neck involvement. Synovial sarcoma of the infratemporal fossa is very rare In this article, we report the fourth case of SS of infratemporal fossa and the first case with intracranial extension via the foramen ovale. A 31-year-old man admitted with a one-year history of intense pain in his right jaw. On physical examination, there was only hyperesthesia over the right mandible side. Computed tomography (CT) and magnetic resonance imaging (MRI) showed a mass in the infratemporal fossa and intracranial extension from the foramen ovale. The mass was surgically removed en bloc. Postoperative pathological examination reported the mass as a biphasic-type synovial sarcoma. The patient who received postoperative chemoradiotherapy had no recurrent disease for one year. The patient is still being followed in our clinic.

OBJECTIVE: To describe 2 subapproaches of the middle fossa approach: the transillumination method and transection of lines using the foramen spinosum, greater superficial petrosal nerve, and trigeminal impression to locate the malleus head for safe identification and decompression of the geniculate ganglion and facial nerve. STUDY DESIGN: Cadaver study. SETTING: A tertiary university hospital anatomy laboratory. SUBJECTS AND METHODS: The present study was conducted using 7 formalin-fixed cadaver heads (14 sides). A 0° endoscope was introduced into the external ear canal toward the posterosuperior quadrant of the tympanic membrane, after which transillumination was used to locate the malleus head. The brightest point indicated the convergence of the greater superficial petrosal nerve and a line drawn along the superior semicircular canal. An additional line was drawn parallel to the petrous ridge from the foramen spinosum and along the pathway of the greater superficial petrosal nerve. A third line connected the trigeminal impression to the zygomatic root. The area posterior to the intersection of these 2 lines separately with the third line was considered the zone of location of the malleus head. Among 17 patients undergoing surgery for facial paralysis between 1993 and 2011, transillumination was used in 6 patients to identify the malleus head to locate the geniculate ganglion. RESULTS: These techniques were proven to be reliable in locating the malleus head to find the geniculate ganglion in 14 dissected cadaveric temporal bones. CONCLUSION: Two methods of locating the malleus head for facial decompression were defined.

RESUMO

OBJECTIVE: To evaluate the effectiveness of micronized flavonoid fraction in preventing cisplatin ototoxicity in a guinea pig model. METHODS: This study was conducted on 23 guinea pigs in the Animal Laboratory of Izmir Atatürk Training and Research Hospital. Animals were divided into three groups: Group 1 consisted of eight animals receiving cisplatin only; Group 2 contained eight animals receiving cisplatin+micronized flavonoid fraction; and Group 3 contained seven animals that received micronized flavonoid fraction only. Their cochlear reserve was evaluated by measuring the distortion product otoacoustic emission on days 0 and 7. RESULTS: In Groups 1 and 2, the intragroup signal-noise ratios were statistically different at all frequencies tested (based on negative ranks, p<0.05). In Group 3, the intragroup signal-noise ratios did not differ significantly at the frequencies tested (p>0.05). Comparison of the three groups showed statistically significant differences among the groups (p<0.05). The post hoc Bonferroni correction showed statistically significant differences among all three groups (p<0.016). The median signal-noise ratio of the three groups tended to increase (z-value was positive for all the frequencies tested; p<0.01). CONCLUSION: Micronized flavonoid fraction (Daflon) is effective against cisplatin-induced ototoxicity in guinea pigs.

RESUMO

OBJECTIVE: To investigate the histopathological changes and the expression of vascular endothelial growth factor (VEGF), inducible NO-synthase (iNOS), endothelial NO-synthase (eNOS), interleukin (IL)-1ß, and IL-17 in the rabbit middle ear mucosa after direct gastric content exposure. METHODS: Exploratory controlled study in which histological and immunochemical features were studied after gastric content-induced inflammation was established in rabbits. Sixteen healthy rabbits were divided into two equal groups. Gastric contents of an animal were injected into the middle ear of the same animal for 20 days. Saline was injected into the middle ear of the animals in the control group. The rabbits were humanely killed on day 27. Inflammation was assayed by light microscopy. Immunochemical staining was performed for VEGF, iNOS, eNOS, IL-1ß, and IL-17 expression. Experimental and control animals were examined using the same protocol. RESULTS: The expression levels of VEGF, iNOS, IL-1ß, and IL-17 differed significantly between the experimental and control groups (p=0.018, p=0.010, p=0.002, and p=0.002, respectively). The expression level of eNOS was not significantly different between the two groups (p=0.132). CONCLUSION: This study demonstrates that gastroesophagial reflux induced middle ear inflammation is associated with increased expression of VEGF, IL-1ß, IL-17, and iNOS.
