Objectives: The study's primary objective was to compare the quality of life (QoL) and external auditory canal (EAC) hygiene among patients who underwent bony mastoid obliteration or meatoplasty after canal wall down (CWD) mastoidectomy. Methods: A prospective, observational, controlled cohort study was conducted at our tertiary referral university hospital. Twenty‐eight patients older than 16 years of age with chronic otitis media who underwent CWD mastoidectomy were included. Two cohorts were followed: CWD mastoidectomy followed by mastoid obliteration (Group 1, n = 14) and CWD mastoidectomy followed by meatoplasty (Group 2, n = 14). The main outcome measures of total COMBI score (postoperative 6‐month QoL) and EAC hygiene were compared between the groups. Results: The average age of the patients was 36.14 (12. 22) years; 15 (53.6%) were female and 13 (46.4%) were male. There were no differences in demographic variables, preoperative findings, or COMQ‐12 (preoperative QoL) scores between groups. The average COMBI score of Group 1 (49.0 [8.66]) was not significantly different from Group 2 (46.79 [7.76]) (p =.482). Poor EAC hygiene was observed in eight (57.1%) patients in Group 2 and three (21.4%) patients in Group 1 (p =.06). In Group 1, no resorption of graft material was observed in 10 (71.4%) patients, minor resorption was observed in three (21.4%) patients, and significant resorption was observed in one (7.1%) patient. There were no significant differences in audiological findings between groups (p >.05). Conclusion: There were no significant differences regarding short‐term postoperative QoL, EAC hygiene, or hearing outcomes between patients who underwent bony mastoid obliteration or meatoplasty after CWD mastoidectomy. Level of Evidence: 1b (individual prospective cohort study). [ABSTRACT FROM AUTHOR]

Objective: The aim of this study was to translate the Chronic Otitis Media Benefit Inventory (COMBI) into Turkish and evaluate the questionnaire's reliability in assessing benefit outcomes in patients after ear surgery. Methods: A total of 30 patients with chronic otitis media who underwent ear surgery were asked to fill out the translated Turkish version of the COMBI questionnaire six months after their surgery twice, 10 days apart. The patients were divided into two groups in two different ways based on surgical and audiological outcomes. These were surgical success (SS), surgical failure (SF), audiological success (AS), audiological failure (AF) groups. Student's -t test was performed to show the differences in the COMBI scores of the groups. Cronbach's alpha value was calculated to test internal consistency, Pearson's correlation coefficient was measured to demonstrate test-retest reliability and factor analysis was run. Results: The average score of the SS group was 51.08 and significantly higher than the score of the SF group (42.40) (p=0.012). There was, however, no statistically significant difference between the average scores of the AS and the AF groups (p=0.330). A Cronbach's alpha value of 0.862 was found. Pearson's r value was calculated 0.810. Factor analysis showed that a three-factor solution explained the 70.2% of the variance. Conclusion: The Turkish version of the COMBI is a valid test with high test-retest reliability. It should be used with objective assessment tools for better understanding how patients benefit from the surgery. [ABSTRACT FROM AUTHOR]

Objective: The aim of this study was to translate the Chronic Otitis Media Questionnaire-12 (COMQ-12) into Turkish, evaluate the internal consistency of the test and test-retest reliability, and validate the adaptation for further use in Turkish studies. Methods: A total of 50 healthy subjects and 50 patients with chronic otitis media (COM) have completed a translated Turkish version of the COMQ-12. Healthy subjects were asked to complete the test twice. A statistical analysis was performed to evaluate the validity and test-retest reliability of the questionnaire. Patients were divided into three groups. Group 1 were patients with COM; Group 2 represented the first test of the control group; and Group 3 represented the second test of the control group. Cronbach's test was performed to test internal consistency, and Spearman's test was performed to evaluate test-retest validity. Results: The average score was 30.64 for Group 1, 3.60 for Group 2, and 3.66 for Group 3. The COMQ-12 score of the patient group was significantly higher than the score of the control group (p<0.001). The area under the receiver operating characteristics curve value was calculated as 0.992, which showed a strong diagnostic accuracy, and the cut-off point was defined as 9. A Cronbach's alpha value of 0.810 was found. Spearman's rank correlation coefficient value (Spearman's rho) was calculated as 0.920. Conclusion: The Turkish adaptation of the COMQ-12 is a consistent and valid test with high sensitivity and specificity that can be used in Turkish for further studies instead of the original questionnaire.

Objective: Primary mucosal malignant melanoma of the head and neck (HN-PMMM) is an aggressive and uncommon neoplasm. Herein, we present a series of 33 patients and the results of treatment, and aimed to determine prognostic factors in HN-PMMM.Methods: Patients who were diagnosed as having HN-PMMM in our reference hospital, between 2005 and 2014 were evaluated. Thirty-three of these patients who had follow-up data were included. Surgical margin status was extracted from the original pathology reports. Archived materials were retrieved for the histopathologic findings: ulceration, necrosis, lymphovascular invasion, perineural invasion, pigmentation, and presence of an in situ component. Mitotic activity was evaluated using phosphohistone H3 (PHH3) immunohistochemical staining.Results: We found an association of PHH3 mitotic activity with overall survival in a univariate analysis and to our knowledge, this is the first report among the available case series of HN-PMMM to evaluate mitotic activity using immunohistochemical staining. We also investigated the relationship between multicentricity and locoregional recurrence, which the authors believe is also a first.Conclusion: PHH3 mitotic activity can be used a prognostic factor for head and neck mucosal malignant melanoma.

The aim of the present study was to describe the use of the endoscopic-assisted cochlear implantation in cases with an unsuccessful standard surgical technique because of not achieving adequate exposure to the round window (RW). Three patients with a bilateral profound hearing loss were operated using an endoscopic-assisted cochlear implant procedure at our tertiary university referral center between 2012 and 2014. In all of the patients, a retroauricular "c" shaped incision was performed and a subperiosteal pocket was created. Standard cortical mastoidectomy and posterior tympanotomy were accomplished using a otomicroscope. However, RW and promontory could not be seen using this approach. The tympanomeatal flap was elevated and the middle ear cavity was entered A rigid 0 degree endoscope (2.7 mm wide, 18 cm in length) (Karl Storz company, Tuttlingen, Germany) and a connected HD camera system (Karl Storz Company, Tuttlingen, Germany) were used to expose RW through posterior tympanotomy, and a drill was passed through the external ear canal. The RW niche was removed using a diamond burr under endoscopic view; the endoscope was placed through the external ear canal, and electrodes were transferred through posterior tympanotomy. The electrodes were fully inserted under the endoscopic view in all cases. Endoscopic-assisted cochlear implantation may be a safe alternative surgical technique in cases where surgeons are not able to visualize RW and promontory using a microscope. [ABSTRACT FROM AUTHOR]

We present a case of a teratoma with somatic type malignancy (TSM) in the form of papillary renal cell carcinoma (pRCC) within supraclavicular and retroperitoneal lymph node metastases of a testicular pure teratoma. Resection of both masses revealed a teratoma without any other germ cell tumor component. A papillary carcinoma component was also detected intermingled with the teratomatous elements. The carcinoma cells displayed eosinophilic cytoplasm and prominent nucleoli. Groups of foamy histiocytes in the fibrovascular cores was a striking finding that brought pRCC to mind. Immunoreactivity for CK7, PAX8, AMACR, CD10, napsin, and vimentin along with morphologic findings confirmed renal cell differentiation. No radiological evidence of a primary renal cell carcinoma was found in the kidney. Consequently, pRCC arising in a teratoma was diagnosed. TSM is described as teratoma with a malignant component that is typically encountered in other organs and tissues. TSM in the form of pRCC is an extremely rare entity. Our case is the second example of a testicular germ cell tumor metastasis with a somatic malignancy in the form of pRCC. In conclusion, carcinomas of renal cell differentiation should be kept in mind as a rare form of TSM, especially in metastatic germ cell tumors. [ABSTRACT FROM AUTHOR]

OBJECTIVE: To compare two different percutaneous bone-anchored hearing aid (BAHA) abutment systems regarding operation time, scar healing, quality of life, implant stability, audiologic results, and complications. MATERIALS and METHODS: The study involves a prospective multi-center clinical evaluation. Thirty-two consecutive patients who had undergone BAHA surgery from January 2011 to January 2013 in two tertiary centers were included in the study. The Glasgow Inventory Benefit Score was used to assess the patients at least 6 months after surgery. The operation time and complications were recorded. Implant stability quotient (ISQ) values were recorded using resonance frequency analysis. Holger's classification was used to evaluate skin reactions. RESULTS: The mean length of the operation was 39.2±4 min for standard abutment and 18.3±5.7 min for hydroxyapatite-coated abutment. ISQ scores were significantly better for standard abutment in all tests. The mean total Glasgow Inventory Benefit Score was 39.3±19 for the standard abutment and 46.3±24.5 for the hydroxyapatite-coated abutment groups, but there was no statistical significance between the two groups. There was no difference in audiological improvement between the two groups after surgery. CONCLUSION: Hydroxyapatite-coated abutment provided a shorter operation time that was significantly different from standard abutment. There were no significant differences between standard abutment and hydroxyapatite-coated abutment regarding audiologic improvement, quality of life, loading time, and complications.

OBJECTIVES: Wideband tympanometry (WBT) measurements show sensitivity to trends in external ear canal/middle ear maturation and changes in middle ear status as a result of different types of dysfunction. This study aims to determine the effects of cochlear implantation (CI) on middle ear status. MATERIALS and METHODS: This is a prospective comparative clinical study that has been done in a tertiary referral center. The patients who underwent unilateral cochlear implantation were included in the study. All the participants were under 18 years of age and had congenital bilateral profound sensorineural hearing loss (SNHL). WBT measurements of implanted ears were calculated and compared to those of non-implanted ears (control group) in the same patient group. The differences in these measurements were subjected to statistical analyses. RESULTS: A total of 48 patients (96 ears) who underwent unilateral CI were included in the study. Our study revealed that significant reductions in the average absorbance ratios occurred at all measured frequencies and that the average resonance frequency increased more significantly in the implanted ears compared with those of control group (p<0.001). The difference in the average peak pressure was not significant among two groups. (p=0.211) CONCLUSION: This study shows that the average absorbance ratio decreases and average resonance frequency increases after cochlear implantation. These findings may be related to increased stiffness in middle and inner ear system. Future studies are needed for more detailed information and recommendations on this topic. [ABSTRACT FROM AUTHOR]

OBJECTIVES: Petrous bone cholesteatoma is a rare pathologic entity and may be a difficult surgical challenge because of potential involvement of the facial nerve, carotid artery, dura mater, otic capsule and superior petrosal or lateral sinus. The objective of this article is to present the endoscope-assisted surgery for petrous bone cholesteatoma. MATERIALS and METHODS: Eight patients (nine ears) who underwent endoscope-assisted petrous bone surgery for cholesteatoma. Pure tone audiogram, magnetic resonance imaging were performed at preoperatively, and at approximately 12 months postoperatively. RESULTS: Endoscope assisted surgery was performed in 8 patients and 9 ears. Of these patients, 6 were male and 2 were females. Median age was 19,5 (range 7-52) years. Hearing was able to preserved in 8 ears (8/9). Recurrence disease was observed one ear in long term follow up (1/9). In another one patient, cholesteatoma pearl was removed in the office. CONCLUSION: Endoscope-assisted surgery can allow removal of cholesteatoma of petrous apex with preserving hearing. It also provides to remove the cholesteatoma via transmastoid approach for perilabyrinthine space as "minimally invasive surgery" instead of middle fossa approach that is standard surgical procedure. In apical and peri-labyrinthine cholesteatomas, endoscopes allow to preserve hearing with middle fossa approach instead of trans-otic/trans-labyrinthine/trans-cochlear approach.

Spontaneous cerebrospinal fluid (CSF) otorrhea frequently occurs without temporal bone trauma, fracture, surgery, or any identifiable causes. It is usually associated with tegmen tympani defects of the temporal bone in adults. The congenital origin theory and the arachnoid granulation theory have been accepted to explain the tegmen tympani defect. Magnetic resonance imaging (MRI) and computed tomography (CT) are used to show the defects, brain tissue, and the meninges. We recently encountered three cases of spontaneous CSF otorrhea with a defect on the tegmental plate of the temporal bone. High-resolution CT (HRCT) scan of the temporal bones showed the tegmen tympani defects. The defects were successfully repaired with temporal muscle fascia or fascia lata graft and fibrin glue using the middle cranial fossa approach via craniotomy. [ABSTRACT FROM AUTHOR]

Introduction: Hydatid Cyst is a zoonotic infection most commonly caused by larvae of the Echinococcus granulosus. Humans are an accidental intermediate host following ingestion of the larvae. Case Report: We report the case of a 16-year-old male patient presenting with a hydatid cyst in the pterygopalatine fossa. There was no pulmonary or hepatic involvement. The definitive therapy comprised excision of the cystic mass and postoperative medical treatment. Discussion: Pterygopalatine fossa involvement is reported in three cases in the literature. In this report we represent a case with pterygopalatine fossa hydatid cyst extending into infratemporal fossa. Conclusion: The hydatid cyst of infratemporal and pterygopalatine fossa is extremely rare. Possibility of hydatid cyst should not be ignored at the differential diagnosis of cystic lesions in head and neck region, especially in endemic areas. [ABSTRACT FROM AUTHOR]

OBJECTIVES: To determine the benefit of a routine plain radiography (X-ray) for confirming the optimal electrode position in cochlear implant surgery. MATERIALS and METHODS: In total, 245 patients (135 males and 111 females) who underwent cochlear implantation in a single tertiary referral center were included in this study. Postoperative plain X-ray findings and electrophysiological tests were retrospectively analyzed. RESULTS: The mean age was 11.4±14.6 years (range, 1–70 years). Overall, 196 (80%) patients were pediatric patients (age, <18 years) and 49 (20%) were adults (age, ≥18 years). The mean rotation of electrode arrays was 1.03±0.17 turns. The plain X-ray revealed that electrode misplacement was present in 5 patients (2%); incomplete insertion in 3 patients, and tip rollover and electrode migration in 1 patient each. A revision was performed for the last patient who had an extracochlear electrode position in the plain X-ray. CONCLUSIONS: Postoperative imaging is mostly used to confirm the electrode array position after cochlear implant surgery. In addition, intraoperative evaluations have low positive predictive value and sensitivity. Thus, this study revealed that postoperative radiological imaging should be considered even when all intraoperative electrophysiological measures and surgical reports are normal.

MATERIALS and METHODS: Ten 7-14 year old experienced cochlear implant recipients were evaluated with the LIFE-UK IHP questionnaire before and after four weeks of use with the Mini Microphone, used in daily activities especially at school. Data logs from recipients were also evaluated for quantification of the use time. Results were analysed for mean change from the baseline questionnaire rating after four weeks of Mini Microphone use. RESULTS: Quality of life scores improved after receiving the Mini Microphone and with four weeks of experience. CONCLUSION: The Wireless Mini Microphone is a desirable device for cochlear implant recipients to improve quality of life. [ABSTRACT FROM AUTHOR]

Objective: The purpose of this study is to retrospectively review the complications of cochlear implantation in pediatric patients. Materials and Methods: The study included 344 pediatric patients (younger than 18 years of age) who had undergone cochlear implantation surgery between September 2005 and May 2010. The patients were regularly monitored, with a mean follow-up period of 31 months (ranging from 9 to 66 months). All of the operations were performed by the same surgeon (YG). Results: 13 major (3.8%) and 12 minor (3.5%) complications were observed. Major complications included local flap failure (3 patients), soft device failure (2 patients), magnet displacement following head trauma ( 2 patients), electrode displacement to vestibule (1 patient), reference electrode migration to dura mater with facial paralysis (1 patient), electrode extrusion from the external ear canal (1 patient), hard device failure after trauma (1 patient), electrode breaking into the mastoid cavity (1 patient) and bleeding from the sigmoid sinus during the operation (1 patient). The implants were removed from 8 of the patients (2.3%) and re-implanted in all of them (2.3%). Minor complications included vestibular symptoms (4 patients), seroma formation (3 patients), recurrent acute otitis media(3 patients), hematoma following head trauma (1 patient), and seizure (1 patient). Conclusion: Power of the study is that all the operations were performed by a single surgeon and sample patients group was homogenous. When compared with the other methods reported, 3.8% major and 3.49% minor complication rates were lower than expected. These complications should be kept in mind during the CI surgery and the surgeon should be work to avoid them and be familiar with them enough to treat them. [ABSTRACT FROM AUTHOR]
