RESUMEN
Objectives Postoperative cerebrospinal fluid (Po-CSF) leak is still a challenging complication of endoscopic endonasal skull base surgery. However, data describing the predictive factors of Po-CSF leak in pure pituitary adenomas is lacking. Aim of this study is to determine the risk factors of Po-CSF leak in a pituitary adenoma group operated via pure transsellar endoscopic approach. Design This is a retrospective cohort study. Setting A single-center academic hospital. Participants Patients operated for a pituitary adenoma between 2015 and 2021 and followed up until June 2022 were included. Main Outcome Measures Demographics, comorbidities, imaging, and outcome were recorded. Univariate and multivariate logistic regression analyses were used to determine the risk factors of Po-CSF leak. Results Of the total 170 patients with a mean age of 47.5 ± 13.8 (min: 15; max: 80), 11 (6.5%) had Po-CSF leak. Univariate analysis revealed age, diabetes mellitus (DM), and tumor volume as predictors of Po-CSF leak. According to the receiver operating characteristic analysis, 7.5 cm 3 of tumor volume was found to be a good cutoff value with a sensitivity of 82% and a specificity of 75%. Hence, multivariable logistic regression model adjusted by age showed that a tumor volume of > 7.5 cm 3 (odds ratio [OR]: 22.9; 95% confidence interval [CI]: 3.8-135.9, p = 0.001) and DM (OR: 8.9; 95% CI: 1.7-46.5; p = 0.010) are strong independent risk factors of Po-CSF leak in pure endoscopic endonasal pituitary surgery. Conclusion Besides younger age and DM, a cutoff value for tumor volume > 7.5 cm 3 is the most remarkable risk factor for Po-CSF leak in pure endoscopic pituitary surgery. These patients should carefully be assessed preoperatively and potential preemptive surgical strategies should be taken into consideration to avoid complications.
RESUMEN
PURPOSE: Our aim was to analyze the patients with diabetic rhino-orbital-cerebral mucormycosis that we have treated in our clinic in the last 5 years, and to reveal the altering conditions with COVID-19. MATERIALS AND METHODS: A retrospective study was conducted on 39 rhino-orbital-cerebral mucormycosis (ROCM) patients with diabetes mellitus between 2017 and 2022. The patients were divided into two groups as those associated with and not associated with COVID-19 and compared. RESULTS: Thirty-nine diabetic patients were included in the study, with 15 (38.5%) of them being COVID-19 associated mucormycosis (CAM) group. CAM patients showed higher orbital involvement and cavernous sinus involvement (p = 0.002 and p = 0.013, respectively). The mortality rate in the non-COVID-19 associated mucormycosis (non-CAM) group was statistically higher in patients with intracranial and cavernous sinus involvement (p = 0.015 and p = 0.033, respectively). The difference between the overall survival of the CAM patients and non-CAM patients was not statistically significant (p = 0.741). CONCLUSIONS: With COVID-19, progressive mucormycosis accompanied by orbital and intracranial involvement is observed more frequently. However, on the contrary, the mortality rate in COVID-19-associated mucormycosis is considerably lower than expected. The fact that temporary immune suppression can be ameliorated with adequate supportive treatment and liposomal amphotericin-B which can be given to patients in high doses may explain this situation. It has been attained hints that the essential factor in the treatment of COVID-19-associated ROCM is the control of the underlying disease and to be cautious in the decision of early aggressive surgery.

PURPOSE: Sellar metastases are rare lesions. Recent improvements in diagnosis and treatment strategies have prolonged survival but increased the probability of metastatic tumors. Evaluation with clinical symptomatology and meticulous laboratory examination is crucial. We present our multicenter national study on sellar metastases to evaluate and underline the main clinical, endocrine, and radiological considerations regarding the diagnosis and endonasal endoscopic management of such rare lesions. METHODS: A medical literature-based retrospective study was planned across 13 neurosurgical centers in Turkey, where a data survey was conducted to collect information regarding sellar metastases surgically treated using the endoscopic endonasal approach, including clinical presentation, radiographic features, primary tumor origin, histopathological confirmation, time to metastasis, treatment, and patient outcomes. RESULTS: Between 2010 and 2020, 54 patients (22 women [40.7%] and 32 men [59.3%]) who underwent surgery with the endonasal endoscopic approach and had pathologically proven sellar metastases (overall incidence, 0.54%) were included. Of the patients, 59.3% had no known malignancy and presented with new-onset symptoms, 79.6% reported headache, 51.9% complained of some degree of visual deficits, and 50% had cranial nerve symptoms. Tissue biopsy was performed in 7.4% of the patients, whereas gross or subtotal resection was achieved in the remaining patients. CONCLUSION: To our knowledge, this is the largest series of patients surgically treated with the endonasal endoscopic approach for sellar metastases. For these patients, the treatment focus should be on management modalities for increasing quality of life instead radical treatment options with survival benefit.

To evaluate the predictive value of CD44 and aldehyde dehydrogenase 1 (ALDH1) expression for prognosis and radiotherapy (RT) response in patients with early-stage laryngeal cancer receiving RT. Forty-four patients with early-stage laryngeal cancer diagnosed between 2002 and 2016 were included in the study. The correlation between RT response and pre-treatment immunohistochemical ALDH1 and CD44 staining was evaluated. In addition, survival times were compared between groups. The mean age of the 44 patients was 59.8 ±9.0 (43-81) years and 41 were male. There were 20 patients in the non-recurrent group (all men) and 24 patients in the recurrent group (21 men). Immunohistochemical positivity for ALDH1 was found to be a significant risk factor for RT failure (p = 0.0001), whereas CD44 positivity (p = 0.114) and age group (p = 0.287) were not significant. ALDH1 positivity was identified as a significant predictor of DFS and RT sensitivity, while CD44 positivity did not differ according to RT response.

BACKGROUND: Cochlear implants are arguably the most successful neural prosthesis today. Cochlear implantation has several difficulties in patients with internal ear anomalies. This study was performed to analyze intraoperative, postoperative findings, and auditory performance of 55 patients who had inner ear malformations and were treated with cochlear implants at Otorhinolaryngology Department of Çukurova University Hospital. METHODS: Auditory performances were analyzed in 30 of 55 patients. Patients with cochlear anomalies were evaluated as group I, patients with vestibular malformation as group II, and patients with the normal bone labyrinth as group III. Listening progress profiles and meaningful auditory integration scale tests were used to determine performances. RESULTS: Comparison between the listening progress profiles test performance of the groups at 12th and 18th month of group I was significantly lower than other groups (P < .05) and reached at the same level after the 24th month. Comparison between the meaningful auditory integration scale test performance of groups at 24th and 36th month of group I was significantly lower than other groups (P < .05). Perilymph gusher was observed in 3 patients who had incomplete partition I malformation. Oozing was observed in 50% of incomplete partition II patients. Facial nerve traced a variant course in 4 of 55 patients and 6 patients had postoperative meningitis. CONCLUSION: Initially patients with inner ear anomalies showed that the level of language development was worse than patients with normal bone anatomy. However, it was shown that they both reached the same point as a result. Facial nerve anomaly and meningitis risk is higher in patients with inner ear malformations.

Abstract Introduction: Human papilloma virus is an etiological risk factor for a subset of head and neck squamous cell carcinomas. HPV has been proven to be a powerful prognostic biomarker for oropharyngeal cancer, but its role in the larynx has not been explored in depth. The developmental mechanisms of laryngeal carcinomas are quite complex and controlled by various factors. Smoking and alcohol are most important risk factors. Recent studies indicate that HPV infection also plays an important role in larynx carcinomas. HPV related laryngeal carcinomas especially occur at the supraglottic region of larynx. Objective: We aimed to determine the frequency of HPV/protein16 positivity in patients with laryngeal carcinoma and association of HPV and/or p16 positivity with variables such as age, sex, smoking habits, tumor localization, lymph node metastasis, recurrence and survival in advanced stage laryngeal carcinoma in our study. Methods: This retrospective study included 90 patients with advanced laryngeal carcinoma. The Control group was 10 normal larynx mucosa specimens. The presence of HPV was investigated polyclonally by polymerase chain reaction, and protein16 with immunohistochemical method. In HPV positive cases, the presence of HPV types 16, 18 were evaluated by polymerase chain reaction. Demographic features of patients were noted. Patient survival and association with HPV/protein16 was determined. Results: Polyclonal HPV positivity was detected in 11 (12.2%) of 90 cases. Out of these 11 cases, HPV 16 was positive in 6, HPV 18 in 4, and both HPV 16 and 18 were positive in 1. In 18 (20%) of the cases, p16 was positive. Six of the cases (6.6%) had both HPV and protein16 positivity. In cases where protein16 alone or HPV and protein16 were co-positive, alcohol use was less and the tumor was found more likely to be localized in the supraglottic area. These ratios were statistically significant. Supraglottic localization of tumor was determined to be increased in protein16 positive cases. The correlation between protein16 positivity and supraglottic area location was determined to be statistically significant (p= 0.011). 55.6% of protein16 positive cases was located in the supraglottic region, 33.3% was glottic and 11.1% was transglottic. Although life expectancy over 5 years were numerically higher in HPV and protein16 positive cases, this was not found to be statistically significant. There was no statistically significant relationship between HPV positivity and mean age, differentiation, smoking and alcohol use, tumor progression, lymph node metastasis, localization, recurrence, cause of mortality and treatment methods in our study. The mean follow-up period of our patients was 6.7 years. Conclusion: The close relationship between HPV and oropharyngeal squamous cell carcinoma could not be shown in larynx malignancy in many studies, including our study. Our findings support a limited role of HPV in laryngeal carcinogenesis. Protein16 is not a reliable surrogate for HPV status in laryngeal cancers and is not a predictor of laryngeal cancer survival. Supraglottic localization of tumor was determined to be increased in protein16 positive cases. The correlation between protein16 positivity and supraglottic area location was determined to be statistically significant. There is a need for more populated clinical trials, where neoplastic proliferation is better demonstrated and the accuracy of the results obtained is supported by different techniques.
Resumo Introdução: O papilomavírus humano é um fator de risco etiológico para um subconjunto de carcinoma espinocelular de cabeça e pescoço. Tem sido demonstrado que o HPV é um poderoso biomarcador prognóstico para o câncer de orofaringe, mas seu papel na laringe ainda não foi explorado em profundidade. Os mecanismos de desenvolvimento dos carcinomas de laringe são bastante complexos e controlados por vários fatores. Tabagismo e álcool são os fatores de risco mais importantes. Estudos recentes indicam que a infecção pelo HPV também desempenha um papel importante nos carcinomas da laringe. Os carcinomas laríngeos relacionados ao HPV ocorrem especialmente na região supraglótica. Objetivo: Nosso objetivo foi determinar a frequência da positividade para o HPV / proteína 16 em pacientes com carcinoma da laringe e a associação da positividade para o HPV e /ou proteína 16 com variáveis como idade, sexo, tabagismo, localização do tumor, metástase linfonodal, recidiva e sobrevivência de carcinoma da laringe em estágio avançado em nosso estudo. Método: Este estudo retrospectivo incluiu 90 pacientes com carcinoma laríngeo avançado. O grupo controle incluiu 10 amostras de mucosa laríngea normal. A presença de HPV foi inves-tigada por anticorpo policlonal através de reação de polimerase em cadeia e a proteína 16 por método imunohistoquímico. Nos casos positivos para o HPV, a presença dos tipos 16 e 18 do foi avaliada por reação de polimerase em cadeia. As características demográficas dos pacientes foram observadas. A sobrevida dos pacientes e a associação com HPV / proteína 16 foram determinadas. Resultados: A positividade com anticorpo policlonal do HPV foi detectada em 11 (12,2%) dos 90 casos. Desses 11 casos, o HPV 16 foi positivo em 6, o HPV 18 em 4 e o HPV 16 e 18 foram positivos em 1. Em 18 (20%) dos casos, a proteína 16 foi positiva. Seis dos casos (6,6%) apresentaram positividade para HPV e proteína16. Nos casos positivos apenas para a proteína 16 ou quando HPV e a proteína 16 foram co-positivos, a ingestão de álcool foi menor e o tumor apresentou maior probabilidade de estar localizado na área supraglótica. Essas proporções foram estatisticamente significantes. A localização supraglótica do tumor foi maior em casos positivos para proteína 16. A correlação entre positividade para proteína 16 e localização da área supraglótica foi estatisticamente significante (p = 0,011). Dos casos positivos para proteína 16, 55,6% foram supraglóticos, 33,3% glóticos e 11,1% transglóticos. Embora a expectativa de vida acima de 5 anos tenha sido numericamente maior nos casos positivos para HPV e proteína 16, isso não foi estatisticamente significante. Não houve relação estatisticamente significante entre positividade do HPV e média de idade, diferenciação, tabagismo e uso de álcool, progressão tumoral, metástase linfonodal, localização, recidiva, causa de mortalidade e métodos de tratamento em nosso estudo. O período médio de seguimento de nossos pacientes foi de 6,7 anos. Conclusão: A estreita relação entre HPV e carcinoma espinocelular orofaríngeo não pôde ser demonstrada na laringe em muitos estudos, inclusive no nosso estudo. Nossos achados confirmam um papel limitado do HPV na carcinogênese da laringe. A proteína 16 não é um substituto confiável para o status do HPV nos cânceres de laringe e não é preditor da sobrevida do câncer de laringe. A localização supraglótica do tumor foi maior em casos positivos para proteína16. A correlação entre positividade para proteína 16 e localização na área supraglótica foi determinada como estatisticamente significante. Há necessidade de ensaios clínicos com amostras maiores, nos quais a proliferação neoplásica seja melhor demonstrada e a precisão dos resultados obtidos seja apoiada por diferentes técnicas.

OBJECTIVE: The aim of this study was to determine the short- and long-term complications after cochlear implantation (CI) procedures and to discuss the management and prevention of these complications. METHODS: The study included a total of 1452 pediatric and adult cochlear implantation procedures performed in our clinic from March 2000 through September 2019. Of the 1452 implantations, 1201 were performed in children and 156 in adults. The minimum follow-up period was three months and maximum was 19 years. The mean age of the patients was 6.7±3.9 years (range, 10 months-69 years) at the time of their respective procedures. Complications were classified as major complications requiring reimplantation, major complications not requiring reimplantation and minor complications. All postoperative complications and treatment methods were examined. RESULTS: A total of 148 (10.1%) complications were observed in the 1452 cochlear implants. Of these, 69 (4.75%) were major and 79 (5.44%) were minor complications. While 40 (2.75%) of the major complications required reimplantation, 29 (1.99%) did not. The most common cause of major complications leading to reimplantation was device failure (29 patients, 1.99%). The most common cause of minor complications was hematoma (21 patients). Total complication rates (6.68%) were significantly higher in children than in adults (3.51%) (p=0.00). CONCLUSION: Our 19 years of clinical experience has shown that CI is a successful and safe procedure that can be performed with low major complication rates. It is important to know the possible complications and to manage them correctly.

INTRODUCTION: Aspiration of foreign bodies is an emergency condition in children and may result in death, especially in children under 3 years of age. Therefore, diagnosis and treatment must be made rapidly. OBJECTIVE: This study sought to summarize our experience with endoscope-assisted rigid bronchoscopy (RB) in the diagnosis and treatment of pediatric tracheobronchial foreign body emergencies to reduce complications and mortality. METHODS: This was a retrospective cross-sectional study. The medical records of 337 children diagnosed with clinically suspected airway foreign body aspiration in the pediatric emergency department were analyzed retrospectively. The patients were divided into 2 groups with endoscopy used during RB in group 1 whereas group 2 was RB only. The surgeons who performed the bronchoscopies completed a survey on the advantages/disadvantages of these 2 procedures. RESULTS: All of the patients had a positive history of suspected foreign body aspiration and foreign bodies were identified in 77.1% of the patients during RB. There were 161 (47.8%) patients in group 1 and 176 (52.2%) patients in group 2. In group 2, 5 patients showed transient hypoxia, and 6 patients had an episode of transient bleeding during the operations. These numbers were 3 and 3, respectively, in group 1. One patient in group 2 suffered cardiac arrest and died during surgery. The authors did not see any long-term complications after these operations and the authors did not find any statistically significant differences between the groups for complication rates. CONCLUSION: The RB is the gold standard procedure for removal of pediatric airway foreign bodies. The survey used in this study and our extensive experience have shown that the distal bronchi and foreign bodies can be visualized more effectively when using a rigid endoscope during RB, especially in children under the age of 3 years. In order to improve the safety of the surgical procedure, the authors propose that endoscope-assisted RB should be used in emergencies concerning foreign bodies in the airways of children.

OBJECTIVES: The aim of the present study was to analyze the outcomes of cochlear implantation (CI) in patients with agenesis of the corpus callosum (CCA). A literature review and a retrospective analysis of our cochlear implant database were performed. MATERIALS AND METHODS: To the best of our knowledge, in the English literature, there was only one case reported with CCA who had undergone CI surgery. This case had Donnai-Barrow syndrome. In the Cukurova University School of Medicine Department of Otorhinolaryngology database, 5 of the 1317 patients who underwent CI surgery who had CCA were selected. The patients' demographic characteristics, operative findings, surgical outcomes, and additional disabilities were investigated. The patients' preoperative and postoperative Listening Progress Profile (LiP) and Meaningful Auditory Integration Scale (MAIS) tests were done to analyze the auditory performances. RESULTS: The participants of the study were 5 (0.38%) individuals (2 male and 3 female patients; ages 5.5, 7.5, 8, 9, and 12 years). Two of the patients had total agenesis, and the other three had partial agenesis of the CCA. In the histories of the patients, one patient had parental consanguinity, and one had febrile convulsion. No patient had an additional disability. None had experienced device failure. No patients were non-users or limited users of cochlear implants. Postoperative LiP and MAIS test scores were improved for all patients nearly as the patients without any deformity. They showed normal auditory performance in the analysis in their postoperative 48 months of follow-up. CONCLUSION: Patients who had CCA are good candidates for CI surgery.

OBJECTIVE: To evaluate all five vestibular end-organ functions (lateral, anterior, posterior semicircular canal, utricule, and saccule) and to investigate the relationship between Dizziness Handicap Inventory (DHI) and vestibular functions prior to CI (cochlear implantation) and at postoperative day 3 and month 3. METHODS: A total of 42 patients (age 16-70years) with normal vestibular functions preoperatively and undergoing unilateral CI were included in this prospective descriptive study. Video head impulse test (vHIT) for three semicircular canal (SSC) functions, ocular vestibular-evoked myogenic potential (oVEMP) for utricule function, cervical vestibular-evoked myogenic potential (cVEMP) for saccule function and DHI for subjective vertigo symptoms were performed prior to CI and at postoperative day 3 and month 3. RESULTS: There was a significant impairment of vestibular function in 12 patients (28.5%) on the implantation side and significant DHI increase was observed in 13 of 42 (30.9%) patients at postoperative day 3 after CI (p<0.05). We found SSC dysfunction in 7 patients (16,6%) who underwent observation with vHIT, saccule dysfunction in 8 patients (19%) with cVEMP and utricule dysfunction in 5 patients (11.9%) with oVEMP on the operated side 3days after surgery (p<0.05). Posterior SSC functions (5 patients) were more affected than lateral SSC functions (3 patients). At postoperative month 3, six patients (14.2%) still had deteriorating results in the objective tests and significant DHI increase was continued in 4 (9.5%) patients (p<0.05). The deterioration in vHIT continued in only 1 (2.3%) patient (p>0.05). The deterioration in cVEMP continued in 5 (11.9%) patients (p<0.05). The deterioration in oVEMP continued in 2 (4.7%) patients (p>0.05). There was a significant correlation between DHI and objective vestibular tests both in the early and late postoperative period (r=0.795; p<0.05). CONCLUSION: Our study showed that both canal and otolith functions can be damaged after CI especially in the early postoperative period. Surprisingly, posterior SSC functions were more affected than lateral SSC. Therefore, a gold standard vestibular test battery that can evaluate each of three SSC canals and two otoliths functions is essential. Since a single vestibular test for this purpose is not available, we recommend the use of the three available vestibular tests together. This test battery, which is capable of evaluating five vestibular end-organ functions in preoperative and postoperative vestibular evaluations, can provide more accurate results not only for CI but also for most otologic surgeries.

OBJECTIVES: The aim of the present study was to compare the therapeutic effectiveness of intratympanic (IT) methylprednisolone and dexamethasone in the initial treatment of patients with idiopathic sudden sensorineural hearing loss (ISSHL). MATERIALS AND METHODS: A total of 46 patients with ISSHL who had been treated with IT methylprednisolone or dexamethasone were included in the present study. Dexamethasone (4 mg/mL) and methylprednisolone (20 mg/mL) were given transtympanically to 22 and 24 patients, respectively, one dosage per day for 5 consecutive days. Audiologic evaluations were performed pretreatment, daily in inpatient clinics, and in the first week and second month after discharge, using four-frequency pure-tone average (PTA) and speech discrimination score (SDS). Audiologic improvement was classified according to the Furuhashi criteria. RESULTS: According to the Furuhashi criteria, the therapeutic success rate was 62.5% (complete improvement 16.7% and marked improvement 45.8%) in the methylprednisolone group, whereas it was 54.6% (complete improvement 27.3% and marked improvement 27.3%) in the dexamethasone group. Therapeutic success was higher in the methylprednisolone group; however, it was not statistically significant. When the audiologic improvement was accepted as >10 dB in PTA, the therapeutic success rates were 83.3% in the methylprednisolone group and 72.8% in the dexamethasone group. The mean (±SD) improvement of PTA before and after treatment was 30.8±21.4 in the methylprednisolone group and 24.7±2.5 in the dexamethasone group. The mean improvement in SDS was 32.6±25 in the methylprednisolone group and 23.7±26.9 in the dexamethasone group. CONCLUSION: IT steroids are safe, effective, and well-tolerated agents in the initial treatment of patients with ISSHL. Despite having different pharmacokinetic characteristics, IT methylprednisolone and dexamethasone have no superiorities over each other in the primary treatment in patients with ISSHL.

Hearing function in older patients may be related to bone structure. We conducted an experiment to evaluate the effect of zoledronic acid on osteoporotic middle ear ossicles in an animal model. Our subjects were 19 female New Zealand white rabbits (38 ears) weighing 2 to 4 kg. We divided the rabbits into three groups: one group consisted of 6 rabbits with osteoporotic ears that were treated with zoledronic acid; the second group was made up of 8 rabbits with osteoporotic ears that were not treated; a control group included 5 rabbits with normal ears that were untreated. After an oophorectomy, the 6 study rabbits were administered 0.1 ml/kg of zoledronic acid intravenously. All rabbits were sacrificed 16 weeks later, and the middle ear ossicles were removed for investigation under light microscopy. Although osteoporosis enhanced the osteoclastic bone resorption of the ossicles, zoledronic acid enhanced osteoblastic activity on osteoporotic middle ear ossicles. The incidence of osteoporosis was 93.8% in the untreated osteoporosis group and 33.3% in zoledronic acid group-a statistically significant difference (OR: 0.24; 95% CI: 0.09 to 0.58; p < 0.001). Osteoporosis appears to increase the resorption of the middle ear ossicles, a process that can be avoided with zoledronic acid administration. Prevention of the effects of osteoporosis in humans may help decrease the irreversible changes in the middle ear ossicles.

OBJECTIVE: The aim of this study was to evaluate the effect of Botulinum toxin type A by injecting in the submandibular and parotid glands on the frequency and severity of sialorrhea. METHODS: Pediatric patients who were referred to our department with sialorrhea were evaluated using their parents' frequency and severity scores of sialorrhea with visual analog scales before and after 3 months of botulinum toxin type A injections. Bilateral submandibular and parotid glands were injected with Botulinum toxin type A. RESULTS: Twenty-seven pediatric patients who were referred to our department with a complaint of sialorrhea were included in this study. Seventeen patients were female and 10 were male. Severe sialorrhea with cerebral palsy was present in all the patients. There were no complications after the procedure. CONCLUSION: Botulinum toxin A injected in the major salivary glands in pediatric patients with neurological disorders is a safe and effective method.
RESUMEN
OBJECTIVE: The aim of this study to compare the outcomes and complications of endoscopic stapes surgery versus microscopic stapes surgery. METHODS: This study involved patients who underwent stapedotomy at the Department of Otorhinolaryngology, Faculty of Medicine, Cukurova University between January 2012 and July 2014. The patients were divided into two groups. Patients in group I were operated with endoscope and patients in group II were operated with microscope. Pure tone audiometry was carried out in all patients preoperatively. Peroperative surgical findings, complications, and duration of surgery were noted and compared between the two groups. Air conduction and bone conduction thresholds were measured at frequencies of 500, 1000, 2000, and 4000Hz, and the mean (±SD) air-bone gap was noted. RESULTS: Mean preoperative air-bone gap was 36.9±6.8dB (23.3-50dB) in group I and 35.1±6dB (26.6-50dB) in group II. Mean postoperative air-bone gap was 9.3±7.1dB (0-30dB) in group I and 13.5±9.7dB (1.6-35dB) in group II. The difference in preoperative and postoperative air-bone gap between the two groups was statistically significant (p=0.023). Patients in group I did not complain of postoperative pain but this was felt in four patients in group II. The difference was statistically significant (p=0.045). CONCLUSION: Endoscopic stapes surgery has many benefits such as good visualization, and easy accessibility to the stapes, oval window niche, and facial nerve. Removal of the scutum and manipulation of the chorda tympani nerve are less frequent with the endoscopic technique.

Diagnostic imaging methods are very important for patients with bilateral sensourinoural hearing loss. Magnetic resonance imaging (MRI) is able to demonstrate the vestibulocochlear nerve and facial nerve in the internal acoustic canal. Also computed tomography can be helpful to determination of the deficiency of the cochlear nerve. Cochlear nerve anomalies are classified into three group according to the magnetic resonance imagings. Patients who have cochlear nerve deficiency may not hear with cochlear amplifications. Auditory brain stem implant (ABI) is most suitable for these cases. In this case report, we presented a 3 years old girls with bilateral totally hearing loss who performed cochlear implantation despite of cochlear nerve deficiency on magnetic resonance imaging (MRI) and computed tomography (CT).

OBJECTIVE: To review the alternative techniques in cochlear implantation and to compare the complications with different techniques. MATERIALS AND METHODS: Patients who had undergone cochlear implantation were reviewed. Those patients who were operated using alternative techniques were selected and evaluated for the cause of their hearing loss and for the type of alternative technique that was utilized. Complication types and rates in these patients were evaluated. RESULTS: In total, 38 patients were operated using alternative techniques following preoperative or intraoperative findings. The mean age of the patients was 8.3 (1-51) years. There were 20 male and 18 female patients. Thirteen patients were operated with a suprameatal approach and 18 with a transcanal approach. Resection of the bony part of the external ear canal and reconstruction (canal wall down technique) was performed in seven patients. Postoperative complications included wound infection, hematoma, chorda tympani injury, and tympanic membrane perforation. CONCLUSION: Cochlear implantation is an effective method in the rehabilitation of sensorineural hearing loss. Complications are rare but can sometimes cause hematoma, taste impairment, tympanic membrane perforation, or wound infections. The standard procedure is not always suitable for patients with temporal bone abnormalities. Surgeons performing cochlear implantation should be aware of these variations and should be able to perform alternative implant techniques in these cases.

OBJECTIVE: To evaluate the satisfaction of patients with a cochlear implant using a Parents' Perspective Questionnaire and analyze the significant parameters. MATERIALS AND METHODS: Patients who received a cochlear implant in Çukurova University between March 2002 and November 2012 were included in the study. Parents were asked to answer the Parents' Perspective Questionnaire. RESULTS: The age ranges of 62 patients were 2-5 years and of 99 patients were 6-11 years and over. In total, 144 parents were satisfied with the cochlear implant. Patients who attended school had more self-confidence, and users of an implant aged over 18 months had better social relations and self-confidence. CONCLUSION: Cochlear implants' positive effect on the quality of life is a fact, but parents have concerns in the preoperative and postoperative periods. Patients and parents should be informed carefully about cochlear implants. Also, patients' satisfaction is correlated with increasing duration of the implant and age.

OBJECTIVES: This study aims to report early postoperative complications and hearing results in patients with chronic otitis media undergoing endoscopic transcanal tympanoplasty. PATIENTS AND METHODS: Twenty-four patients (6 males, 18 females; mean age 25.9 years; range 9 to 46 years) who were operated with endoscopic transcanal tympanoplasty in the Department of Otorhinolaryngology, Faculty of Medicine, Çukurova University between December 2012 and January 2014 were included. Postoperative complication rates, graft success, and hearing outcomes (mean air-bone gap) were evaluated. RESULTS: The mean preoperative air bone gap was found 25.1 dB and the mean postoperative air bone gap was found 20.3 dB. Postoperative duration of hospital was 24 hours. Reperforation was seen in one patient and medialization of the anterior quadrant of the graft was seen in one patient. The mean follow-up time was 7.3 months. CONCLUSION: Endoscopic transcanal tympanoplasty can be easily applied, cheap and safe method and can be given successful results in challenging cases.

OBJECTIVES: This study aims to investigate the effect of primary surgery on the morbidity of reoperative thyroid surgery. PATIENTS AND METHODS: Fifty-seven patients (14 male, 43 female; mean age 41 years; range 21 to 70 years), who underwent reoperative thyroid surgery in our clinic between January 2007 and January 2012 were retrospectively analyzed in terms of vocal cord paralysis, temporary or permanent hypoparathyroidism, and other complications. The patients were classified into two groups. The first group consisted of 42 completion thyroidectomy patients that had undergone the primary operation of unilateral total lobectomy + isthmusectomy in our clinic, whereas the second group consisted of 15 patients that had undergone bilateral subtotal or near total thyroidectomy in another center. Complication rates were compared between the groups. RESULTS: Complication rates were observed as permanent vocal cord paralysis in one patient (1.7%), permanent hypocalcemia in two patients (3.5%) and temporary hypocalcemia in four patients (7%). None of the patients had temporary vocal cord paralysis. The complications in the second group were significantly higher than the first group (p=0.021). CONCLUSION: The minimal operation should be hemithyroidectomy (total lobectomy and isthmusectomy) to minimize the complications. This approach removes the need for the intervention to the previous surgery field during reoperative thyroid surgery.
