RESUMO
INTRODUCTION: Osteogenesis imperfecta (OI) is a common heritable disorder affecting type 1 collagen. The sequelae of OI vary, but hearing loss is a significant complication with 46-58 % of patients having some degree of hearing loss. Previous studies have suggested patients with OI may have conductive, sensorineural, or mixed hearing loss. Majority of these studies focus on the adult population. OBJECTIVES: Identify a relationship between OI and hearing loss in the pediatric population. METHODS: The TriNetx Analytics Network, a federated health research network that aggregates the de-identified electronic health record data of over 78 million patients across the United States, was queried for patients 18 years old or younger with a diagnosis of OI. Patients in this group with diagnosis of sensorineural, conductive, or mixed hearing loss were recorded. Patients with diagnoses of congenital cytomegalovirus, congenital inner ear malformations, and noise-induced hearing loss were excluded from analysis. RESULTS: Out of 3256 patients 18 years old or younger with OI, 10.07 % (95 % CI: 9.06-11.16) had a history of any form of hearing loss, 5.71 % (95 % CI: 4.94-6.57) had conductive hearing loss, 3.01 % (95 % CI: 2.45-3.66) had sensorineural hearing loss, and 1.35 % (95 % CI: 0.98-1.81) had mixed hearing loss. Relative risks for diagnosis of any type of hearing loss, conductive hearing loss, sensorineural hearing loss, and mixed hearing loss were calculated: 5.90 (95 % CI 5.32-6.53), 5.08 (95 % CI 4.42-5.84), 6.18 (95 % CI 5.09-7.51), and 13.86 (95 % CI 10.33-18.59) respectively. DISCUSSION: This study is the largest to date that describes a relationship between OI and conductive, sensorineural, and mixed hearing loss. Pediatric patients with OI are almost five times as likely to have any type of hearing loss. There was a significant increased risk in each subgroup, but conductive hearing loss was the most common for hearing loss in children with OI. The highest risk subtype when compared to controls was mixed hearing loss.

BACKGROUND: The catastrophic and rare nature of an internal carotid artery (ICA) injury during endonasal surgery limits training opportunities. Cadaveric and animal simulation models have been proposed, but expense and complicated logistics have limited their adoption. Three-dimensional (3D) printed models are portable, modular, reusable, less costly, and proven to improve psychomotor skills required for managing different lesions. In this study we evaluate the role of a simplified laser-sintered model combined with standardized training in improving the effectiveness of managing an ICA injury endoscopically. METHODS: A 3-mm defect was created in the parasellar carotid canal of a laser-sintered model representing a sphenoid sinus. Artificial blood was directed to simulate the copious bleeding arising from an ICA injury. Twenty otolaryngologists and 26 neurosurgeons, with varying training and experience levels, were individually asked to stop the "bleeding" as they would in a clinical scenario, and provided no other instructions. This was followed by individualized formative training and a second simulation. Volume of blood loss, time to hemostasis, and self-assessed confidence scores were compared. RESULTS: At the end of the study, time to hemostasis was reduced from 105.49 seconds to 40.41 seconds (p < 0.001). The volume of blood loss was reduced from 690 to 272 mL (p < 0.001), and the confidence scores increased in 95.7% of participants, from an average of 3 up to 8. CONCLUSION: This ICA injury model, along with a formal training algorithm, appears to be valuable, realistic, portable, and cost-effective. Significant improvement in all parameters suggests the acquisition of psychomotor skills required to control an ICA injury.

OBJECTIVE: The present study aimed to compare the effects of bacterial cellulose used for closure of pharyngocutaneous fistulae, a complication of total laryngectomy, with those of primary sutures in a rat model. METHODS: Thirty female Sprague-Dawley underwent experimental pharyngoesophagotomy and were grouped depending on the material used for pharyngocutaneous fistula closure: group I, which received primary sutures alone, group II, which received bacterial cellulose alone; and group III, which received both. After 7 days, the rats were sacrificed. Pharyngocutaneous fistula development was assessed, the gross wound was inspected, and histological examination was conducted. RESULTS: Pharyngocutaneous fistulae developed in 12 rats (41%) in all: 6 from group I (21%), 4 from group II (14%) and 2 from group III (7%). CONCLUSION: Fibroblast density and inflammatory cell infiltration were significantly greater in group III than group I. We concluded that bacterial cellulose may be useful for pharyngocutaneous fistula closure.

AIM: Pycnodysostosis is a rare autosomal, recessive, skeletal dysplasia caused by a mutation in the cathepsin k gene. Pycnodysostosis is characterized by short stature, characteristic facial appearance (delayed closure of fontanelles and cranial sutures, mandibular hypoplasia and angle disorder, blue sclera), and acroosteolysis of the distal phalanges. Our aim was to describe the otorhinolaryngologic findings, differential diagnoses, various treatment options, and followup in eight cases of pycnodysostosis. METHOD: This retrospective clinical study used data from eight patients diagnosed with pycnodysostosis by a single pediatric endocrinologist primarily based on clinical and radiographic findings. All patients were referred to the otorhinolaryngology outpatient clinic by the pediatric endocrinology unit of the Marmara University between February 2013 and March 2015. Detailed medical histories were obtained in all cases and otorhinolaryngologic physical examination, blood assays, electrocardiogram, lateral skull X-rays, chest radiograph, cephalometric investigations, tympanograms, and audiograms were also carried out. Sleep videos of patients were recorded and those with upper airway problems were evaluated for sleep apnea by polysomnography. Informed consent form was obtained from the parents of all patients. RESULTS: Eight patients (7 females and 1 male) displaying proportionate dwarfism were included in the study. They had a mean age of 14.7 years (range: 13-16 y), the mean height of 141.3 cm (range 132-155 cm), and mean weight of 44.4 kg (range: 39.6-49.3 kg). All patients had facial dysmorphism with frontal bossing and the hands and feet had short digits with overlying cutaneous wrinkles that tapered off with large overriding nails. Midfacial hypoplasia and malocclusion were observed in seven of the eight patients (87.5%), four (50%) had micrognathia, and five (62.5%) had proptosis. Tympanograms and audiograms of all patients were type A and normal, and the mean of the pure tone audiogram was 13.3 dB (range: 10-16 dB). All patients had a narrow and grooved palate with disturbed dentition; two of them (25%) had mild markedness of the tongue base, five (62.5%) had grade 3 and three (37.5%) had grade 2 tonsillar hypertrophy, and five (62.5%) had adenoid hypertrophy. One patient (12.5%) had grade 3 Mallampati, four (50%) showed grade 2 Mallampati while three (37.5%) patients displayed grade 1 Mallampati score. Further, while six (75%) patients had no uvular pathology, one (12.5%) patient presented with uvular elongation and another patient had a bifid uvula. Cephalometric measurements such as PAS-UP (mean 5.67 mm; range: 5.0-7.6 mm) and PAS-TP (mean 9.61 mm; range: 8.5-12.2 mm) were lower than that of normal subjects. Video recordings showed that six of the eight patients (75%) had respiratory distress and four (50%) had sleep apnea. Polysomnography in these patients with sleep apnea showed that two had mild OSA (AHI: 18.2 and 20.1 events/hour) and two had severe OSA (AHI: 53.4 and 62.8 events/hour). For upper airway problems, an adenotonsillectomy was performed in two (25%) patients while two others required an adenoidectomy. Positive pressure ventilation was recommended in two patients with persistent sleep apnea after adeno/adenotonsillectomy. However, because of the parental objections, the follow-up polysomnographs could not be obtained. CONCLUSION: Pycnodysostosis is a very rare form of bone dysplasia. Otorhinolaryngologically, proper follow-up of these patients and appropriate treatment of upper airway problems are important to achieve an acceptable quality of life. Adeno/adenotonsillectomy and positive pressure ventilation, used as conservative approaches in treating upper airway problems, are effective and could be used instead of an aggressive surgery such as tracheotomy or maxillomandibular advancement. This study, to the best of our knowledge, is the largest ENT case series on pycnodysostosis.

Calprotectin is an S100 protein and marker of inflammation found in neutrophils and monocytes; S100 proteins are a family of calcium-modulated proteins. The aim of this study was to determine if the serum concentration of calprotectin is higher in patients with laryngeal carcinoma than in patients with benign laryngeal pathologies and controls. The study included 107 participants. The serum calprotectin concentration was analyzed using the calprotectin ELISA (enzyme-linked immunosorbent assay) kit (Calpo AS, Norway). EDTA-serum for analysis was collected prior to surgery from patients with laryngeal carcinoma (n = 41), those with a benign laryngeal pathology (Reinke's edema, vocal nodules, etc.) (n = 32), and healthy controls (n = 34). The median serum calprotectin concentration was significantly higher in the laryngeal carcinoma group (2179.6 µg L-1) than in the benign laryngeal pathology group (727.84 µg L-1) and control group (733.73 µg L-1) (P < 0.05). The median serum calprotectin concentration in patients with advanced-stage laryngeal cancer (5854.,4 µg L-1) was significantly higher than in those with early-stage laryngeal cancer (971.84 µg L-1) (P < 0.05); however, there was not a significant difference in the median calprotectin concentration between the control and benign laryngeal pathology groups (P > 0.05). Furthermore, the median serum calprotectin concentration in the patients with early-stage laryngeal cancer (n = 21) (971.84 µg L-1) was significantly higher than that in the benign laryngeal pathology and control groups (n = 64) (730.6 µg L-1) (P < 0.05). The serum calprotectin concentration was strongly correlated with poor survival and advanced-stage laryngeal carcinoma. Malignant laryngeal cancer patients (n = 4) that died during follow-up had a higher median serum calprotectin concentration (9468.4 µg L-1) than those that remained alive (n = 37) (857.78 µg L-1) (P < 0.05). The serum calprotectin concentration is higher in patients with laryngeal carcinoma than in those with benign laryngeal pathologies and healthy controls. The present findings show that the serum calprotectin concentration might be used as a marker to discriminate between laryngeal carcinoma and benign laryngeal pathologies. Additional research is needed to further assess the value of this parameter as a useful tumor marker for the diagnosis, treatment, and follow-up of laryngeal carcinoma.

Duplication of the internal auditory canal is an uncommon, congenital malformation that can be associated with sensorineural hearing loss owing to aplasia/hypoplasia of the vestibulocochlear nerve. Only 14 such cases have been reported to date. We report the case of a 13-month-old girl with bilateral, congenital, sensorineural hearing loss caused by narrow, duplicated internal auditory canals and discuss the challenges encountered in the diagnosis and treatment of this condition.

Importance: Secondary posttonsillectomy bleeding associated with oozing from multiple sites or overcauterized tonsillar bed deserves special evaluation. Objective: To evaluate the use of an absorbable, flowable gelatin-thrombin hemostatic matrix (GTHM) sealant for secondary bleeding after tonsillectomy. Design, Setting, and Participants: This was a retrospective data analysis, with information gathered from medical records of pediatric patients with secondary posttonsillectomy bleeding treated with the GTHM between 2012 and 2016 at a referral center and a local satellite facility. Forty-two pediatric patients admitted with secondary bleeding after tonsillectomy characterized by diffuse bleeding, multiple bleeding sites, or an overcauterized tonsillar bed, were treated with GTHM. Exclusion criteria were a bleeding disorder, genetic syndrome associated with abnormal oropharyngeal anatomy, and hemorrhage from a single site. Exposures: GTHM was used to treat posttonsillectomy secondary bleeding. Main Outcomes and Measures: Patient medical records were reviewed for information relevant to this study: (1) patient history, the tonsillectomy surgical technique used, and whether there were prior bleeding episodes (and if so, methods of treatment); (2) physical examination and laboratories on presentation, operative report details, and results of treatment; (3) hospital course and whether any further bleeding episodes occurred; and (4) hospital follow-up information (range, 3-20 months). Results: The study population comprised 22 boys (52%) and 20 girls (48%) (a total of 42 patients), and the mean (SD) age was 7 (2.7) years (range, 4-14 years). Two patients had presented with recurrent secondary bleeding necessitating multiple operations, but the others had only 1 episode. The mean day of occurrence of bleeding was on the eighth day (range, day 7-12; median, day 10). Only 2 patients required blood transfusions: they were the same patients who underwent multiple operations for recurrent episodes of secondary bleeding. All patients except for 1 (41 of 42) were discharged without further bleeding following treatment. No adverse effects were reported. Conclusions and Relevance: Results suggest that GTHM is generally simple, safe, and effective for use in the treatment of posttonsillectomy secondary bleeding types not associated with a direct vein or artery source but oozing from multiple sites and/or overcauterized tonsillar bed that cannot be stopped by traditional hemostatic methods.

Background. Ewing sarcoma (ES) is a high-grade malignant tumor that has skeletal and extraskeletal forms and consists of small round cells. In the head and neck region, reported localization of extraskeletal ES includes the larynx, thyroid gland, submandibular gland, nasal fossa, pharynx, skin, and parotid gland, but not the external ear canal. Methods. We present the unique case of a 2-year-old boy with extraskeletal ES arising from the external ear canal, mimicking auricular hematoma. Results. Surgery was performed and a VAC/IE (vincristine, adriamycin, cyclophosphamide alternating with ifosfamide, and etoposide) regimen was used for adjuvant chemotherapy for 12 months. Conclusion. The clinician should consider extraskeletal ES when diagnosing tumors localized in the head and neck region because it may be manifested by a nonspecific clinical picture mimicking common otorhinolaryngologic disorders.
RESUMO
This retrospective review aims to evaluate the postoperative morbidity and mortality of 30 patients with Down syndrome who underwent adenotonsillectomy between June 2012 and December 2015 in a tertiary referral center. Mean age was 7.8 with a range of 3-12. There were 20 (66.6 %) male and ten (33.3 %) female patients. Mean follow-up was 23 months with a range of 7-43 months. 23 (76.6 %) of 30 patients had been operated due to obstructive tonsillar and adenoid hypertrophy, whereas seven (23.3 %) of them operated for chronic recurrent infections. All of the patients had undergone adenotonsillectomy operation; one patient had also bilateral tympanostomy tube insertion. Hospital stay was noted 1.3 days in average with a range of 1-3 days. Anesthetic complications of persistent bradycardia and postextubation respiratory difficulty occurred in two (6.6) patients. Patient who had intraoperative bradycardia necessitated intensive care unit stay and pacemaker implantation during follow-up. 3 (10 %) patients had late onset hemorrhage between days 7 and 10 and required intraoperative bleeding control. We did not experience any other morbidity and mortality except the abovementioned ones. In conclusion, adenotonsillectomy in patients with Down syndrome is a worthwhile operation with certain risks and these operations should better be performed by the tertiary referral centers which have the capacity to deal with the complications.

Backround. Thyroglossal duct cyst (TDC) is a developmental abnormality of the thyroid gland. Due to embryological remnants of thyroid tissue located in the TDC, the same malignant tumors that develop in the thyroid gland can also develop in the TDC. Methods. We present the unique case of a 39-year-old female with simultaneous de novo papillary carcinoma in a TDC and the thyroid gland. Results. With the suspicion of simultaneous papillary carcinoma in the TDC and the thyroid gland, Sistrunk procedure with total thyroidectomy and central neck exploration was performed. Conclusion. The clinician should have a high index of suspicion upon encountering papillary carcinoma of the TDC to differentiate de novo papillary carcinoma in the TDC from those originating from the thyroid gland, because papillary carcinoma in TDC may originate from an occult thyroid papillary carcinoma.
RESUMO
OBJECTIVE: Sudden sensorineural hearing loss (SSNHL) is defined as hearing loss of at least 30 dB occurring within three days over at least three contiguous frequencies. The etiology of SSNHL cannot always be precisely determined; in such cases, this condition is termed idiopathic SSNHL (ISSNHL). This unique study investigates the relationship between ISSNHL and positive family history for ISSNHL. MATERIALS AND METHODS: In total, 125 patients diagnosed with ISSNHL were retrospectively reviewed. The presence of ISSNHL in the family medical history and degree of kinship of family members diagnosed with ISSNHL were determined. For univariate analysis, a chi-squared test and/or Fisher's exact test was used for between-group comparisons of qualitative variables; a t-test was used for quantitative variables. Significant variables in the univariate analysis were introduced into stepwise logistic regression for multivariate analysis. P<0.05 indicated statistical significance. RESULTS: Fifty-nine (47.2%) patients were male and 66 (52.8%) were female. Statistical analysis revealed no significant difference between sex and development of ISSNHL (p=0.04). Forty-two (33.6%) patients had a family medical history of ISSNHL, whereas 83 (66.4%) did not. A statistically significant association between the development of ISSNHL and a family history of ISSNHL was observed (p<0.05). CONCLUSION: Our study supports an association between ISSNHL and genetic predisposition. Proving genetic susceptibility to ISSNHL will lead to improvements in the prediction, early diagnosis, and treatment of this disease.

OBJECTIVE: The aim of this study was to determine whether the neutrophil-to-lymphocyte ratio (NLR) can be used as a predictor for deep neck space infections (DNSIs) that occur as a complication of acute bacterial tonsillitis in the pediatric population. MATERIALS AND METHODS: We evaluated the NLR values of 180 pediatric patients diagnosed with acute bacterial tonsillitis with or without DNSI who presented to the Otolaryngology Department of Marmara University Hospital between 2010 and 2013. In cases in which DNSI was suspected, the patients underwent complete otolaryngological examination and radiological imaging including CT and MRI. NLR was calculated in all the subjects and was compared between the patients with acute bacterial tonsillitis without DNSI and those with DNSI. RESULTS: With regard to the tonsillitis-related complications, 17 patients had peritonsillar abscess (9.4%); five, parapharyngeal abscess (2.8%); and two, retropharyngeal abscess (1.1%). The mean NLR was significantly higher in the patients of acute bacterial tonsillitis with DNSI (P<0.05). The optimum cut-off value of NLR was determined to be 5.4. CONCLUSION: This study is the first to investigate the relationship between NLR and DNSI as a complication of acute bacterial tonsillitis. The results demonstrated that the NLR value could be a potential laboratory parameter for diagnosing DNSIs.

A nonrecurrent laryngeal nerve variant of the inferior laryngeal nerve is very rarely seen, and surgeons should keep it in mind during thyroid surgery. Preoperative findings, like situs invertus and dysphagia lusoria, may be suggestive of a nonrecurrent laryngeal nerve. However, these findings always have not to be together with nonrecurrent laryngeal nerve, like our case.
RESUMO
Parapharyngeal space tumors are very rarely seen, and surgical approach to these tumors has not been well established. Most of these tumors are benign and originated from salivary glands and neurogenic in nature. In this case, we report a patient who has a trigeminal schwannoma extending into the deep parapharyngeal space and explain our surgical approach.

Larynx and adjacent anatomical structures have complicated physiological functions and mechanical features. Traffic accidents, penetrating stab wounds and shot wounds, sports matches, and occupational accidents cause external laryngeal trauma. In the management of laryngeal trauma, maintenance of airway patency has priority. In this case report, we will mention of a 15-year-old male patient with a blunt laryngeal trauma and also the approach to laryngeal traumas.

This study reports a patient having olfactory neuroblastoma complicated by syndrome of inappropriate antidiuretic hormone secretion. Olfactory neuroblastoma is a rare tumor that begins in the olfactory membrane. Only 10 cases have been reported previously. Because of having nonspecific symptoms, most patients manifest at an advanced stage at the time of diagnosis. Olfactory neuroblastoma may show local invasion and/or distant metastasis. We demonstrated preoperatively clinical and biochemical parameters consistent with antidiuretic hormone syndrome turned to normal ranges after the treatment. Surgery, chemotherapy, and radiotherapy are the choices of treatment; among these, surgery is an indispensible treatment.

OBJECTIVE: The aim of this study was to evaluate the effectiveness of oral steroid treatment versus combined oral and intratympanic dexamethasone injection for idiopathic sudden sensorineural hearing loss. METHODS: This was a retrospective case review in which 30 patients in the oral steroid group and 39 patients in the combined oral and intratympanic steroid injection group were compared. RESULTS: The comparison of the initial pure tone audiometry (PTA) threshold results revealed a significant difference between the systemic steroid (SS) group and the systemic and intratympanic steroid group. The initial PTA was 74.33 ± 22.64 dB (mean ± SD) in the SS group and 87.49 ± 26.22 dB (mean ± SD) in the intratympanic steroid group. The difference in the initial PTA results was statistically significant between the SS group and intratympanic steroid group (P < 0.05, P = 0.032). The pure-tone gain in the SS group was 20.97 ± 27.47 dB (mean ± SD), and that of the group treated with both systemic and intratympanic steroids was 19.36 ± 22.16 dB (mean ± SD) (P = 0.49). CONCLUSIONS: The results of this study indicate that, in sudden sensorineural hearing loss, the administration of intratympanic steroids in conjunction with SS therapy appears to have the same effect on the restoration of hearing "as the effect obtained using SS therapy alone."

OBJECTIVES: The aim of this study was to investigate whether there is a significant correlation between intra- and postoperative electrically evoked stapedius reflex thresholds (eSRTs) in children with cochlear implants. METHODS: Sixty-five pediatric cochlear implant users were included in this study. All patients had congenital prelingual hearing loss. The round window approach was used in all patients. The eSRTs were intraoperatively measured using the 1st, 3rd, 6th and 12th electrodes of the cochlear implant. The measurements taken during the first fitting of the device were taken again one month after surgery. We used paired-sample t-tests to determine the correlation between intra- and postoperative eSRTs. RESULTS: The eSRT analysis revealed a statistically significant difference between the intra- and postoperative thresholds. A correlation analysis did not reveal any correlation between intra- and postoperative eSRTs. CONCLUSION: Intraoperative eSRT measurements were unable to predict early postoperative eSRTs.
