Circulating calprotectin as a biomarker of laryngeal carcinoma.

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.

Is it safe to perform adenotonsillectomy in children with Down syndrome?

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.

Trigeminal schwannoma extending into the parapharyngeal space.

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.

Pediatric acute external laryngeal trauma.

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.

Characterization of hearing loss in pediatric patients with osteogenesis imperfecta.

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.

Syndrome of inappropriate antidiuretic hormone secretion associated with olfactory neuroblastoma.

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.

Systemic steroid versus combined systemic and intratympanic steroid treatment for sudden sensorineural hearing loss.

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."

Electrophysiologic assessment of the subclinical changes in facial functions after parotidectomy.

OBJECTIVE: Our objective was to evaluate whether there was a subclinical change in the functions of the facial nerve after parotidectomy. METHODS: Facial nerve functions of 21 patients who had parotidectomy between January 1999 and December 2003 were assessed using electromyography (EMG) at least 5 years after the surgery. RESULTS: There was no significant difference between both sides of the face in the EMG amplitudes (P > 0.05) except for the amplitudes obtained from the site of nasolabial sulcus (P < 0.05). In the patients who underwent total parotidectomy, the EMG amplitudes were significantly different for both sides of the face (P < 0.05). No significant difference was found in the comparison of other measurements performed by EMG. CONCLUSIONS: Tumor histopathologic type (benign or malignant) and type of parotidectomy (superficial or total) do not cause a subclinical dysfunction of the facial nerve after parotidectomy in the patients who also have clinically normal facial functions. The only exception to this contention is the subclinical dysfunction in nasal branches of the facial nerve in total parotidectomy cases.

Incudostapedial rebridging ossiculoplasty with bone cement.

OBJECTIVE: The purpose of this study is to evaluate hearing results of our experience with ionomeric bone cement repair of ossicular discontinuity between incus and stapes. STUDY DESIGN: Case series with chart review. SETTING: Tertiary referral center. SUBJECTS AND METHODS: One hundred thirty-six patients who underwent incudostapedial rebridging ossiculoplasty with ionomeric bone cement were included in the study. Preoperative and postoperative audiologic results of incudostapedial rebridging ossiculoplasty with bone cement were evaluated. One year of follow-up is provided. RESULTS: The postoperative air-bone gap was less than 20 dB in 81.6 percent after one year. The mean preoperative and postoperative pure-tone avarages of the patients were 52.82+/-5.59 and 32.81+/-7.18 dB, respectively (P<0.01). The mean preoperative and postoperative air-bone gaps were 35.83+/-4.73 and 16.54+/-5.01, respectively (P<0.01). There were no statistically significant differences among the hearing results of different types of surgeries (P>0.05). No complications in the middle ear related to bone cements were encountered. CONCLUSIONS: Incudostapedial rebridging ossiculoplasty with ionomeric bone cement is a reliable method for ossicular reconstruction that is cost effective and offers satisfactory hearing results in selected patients.

Surgical treatment of inverted papilloma.

Inverted papilloma (IP) is the most common benign tumor of the nose and the paranasal sinuses and constitutes almost 0.5% to 4% of the primary nasal tumors. In this study, our objective was to retrospectively review the results of surgical treatment of IP.Sixty-eight patients with a histopathologically proven diagnosis of IP were retrospectively evaluated. Two patients who had an associated squamous cell carcinoma were excluded from the study. Ten patients were operated on for revision surgery, and 56 eventually had a primary tumor. Patients operated on for primary tumor were included in this study. Nasal obstruction was the most frequent symptom observed in 50 patients (89%). The origin of the tumor was most common at the maxillary sinus, the lamina papyracea, and the ethmoid sinus. Endoscopic endonasal resection, endoscopic endonasal resection with the Caldwell-Luc procedure, medial maxillectomy after lateral rhinotomy (LR), and endoscope-assisted medial maxillectomy with LR approaches were used. The patients operated on only with medial maxillectomy after an LR procedure have a recurrence rate of 28% (2 patients). Endoscopic endonasal resection has a recurrence rate of 9% (2 patients). Recurrence observed after endoscopic endonasal resection with Caldwell-Luc procedures was 7% (1 patient). One recurrence (8%) was determined after an endoscope-assisted medial maxillectomy after LR. No major postoperative complications were observed after surgery.In conclusion, IP can be treated both with internal and external approaches. The type of surgery should be determined according to the tumor stage. Combined internal and external approaches have less recurrence rates in advanced cases. Endoscopic endonasal resection should be used in early-stage tumors.

Primary hydatid cyst of the infratemporal fossa.

Hydatid cyst disease is a rare parasitic disease caused by the larval stage of Echinococcus. This parasite in the larval stage can thrive in many parts of the body, most frequently in the liver. Head and neck involvement of the disease is rare. Herein, we present a case of primary hydatid cyst occurring in the infratemporal fossa, which is an extremely rare localization.

Alveolar soft part sarcoma of the tongue.

Alveolar soft part sarcoma is a rare type of sarcoma that usually affects young adult women. It occurs mostly in the lower extremities, and nearly one quarter of the cases are found in the head and neck region. The most common site of origin in the head and neck region is the tongue followed by the orbit. Herein, we present an unusual case of alveolar soft part sarcoma of the tongue in an 18-year-old woman. The clinical, diagnostic, and therapeutic features of this quite rare entity were discussed.

Surgical simulation of a catastrophic internal carotid artery injury: a laser-sintered model.

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.

Outcomes of otologic surgeries with special interest in learning curves of residents in a tertiary referral setting.

OBJECTIVES: We evaluated outcomes of otologic surgeries with a special interest in learning curves of residents in a tertiary referral setting. METHODS: A retrospective review of the outcomes of 811 otologic operations was performed. The outcomes of faculty staff (group 1), senior residents (fifth year; group 2), and residents (fourth year) under supervision of the faculty staff (group 3) were assessed and compared. The faculty staff were available for consultation if needed and were ready to intervene at any stage for group 2. RESULTS: There were 397 female patients (48.95%) and 414 male patients (51.04%) from 17 to 71 years of age. There was no statistically significant difference between the groups regarding graft take rate or hearing outcome (p > .05). CONCLUSIONS: The otologic training of residents appears to be successful in Turkey, as the surgical outcomes of residents were comparable to those of faculty staff.

Synchronous bilateral carotid body tumor and vagal paraganglioma: a case report and review of literature.

We present a case of synchronous bilateral carotid body tumor and vagal paraganglioma in a 49-year-old man who presented with 3 months history of tenderness and palpable neck masses bilaterally. An encapsulated mass which was thought to be a carotid body tumor and an incidental 3 cm x 2 cm, 5 cm x 1 cm, 5 cm mass which seemed to be originated from vagus nerve were dissected from the left side. Pathology revealed carotid body tumor and vagal paraganglioma. Six months after the first operation, the carotid body tumor on the right side was totally excised. A discussion of this case is followed by a review of the literature surrounding this rare clinic and pathological entity.

Comparison of pharyngocutaneous fistula closure with and without bacterial cellulose in a rat model.

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.

Audiovestibular disturbance in patients with systemic lupus erythematosus.

OBJECTIVE: The aim of this study was to evaluate the audiovestibular disturbance in patients with systemic lupus erythematosus (SLE). STUDY DESIGN AND SETTING: Twenty-eight patients with SLE and 28 healthy control subjects were included. Pure-tone audiometry, impedance audiometry, and electronystagmography (ENG) were used for baseline evaluation. Laboratory tests were carried out. Cranial and brain stem magnetic resonance imagings (MRI) were undertaken. RESULTS: Nineteen (67%) patients reported audiovestibular symptoms. Sensorineural hearing loss was found in 6 (21%) patients. Abnormal results on ENG were significantly higher (50%) (P < 0.01). Abnormal laboratory data were available from 26 patients (P < 0.05). MRI did not show any pathosis. CONCLUSION: The audiovestibular disturbances in SLE are more prevalent than previously recognized. Although no cause and effect relationship can be established by this type of study, it appears that a relationship exists. SIGNIFICANCE: Audiologic research should be directed toward routine, pure tone audiometry, and ENG assessment for patients with SLE to enable crucial treatment.

Noninvasive assessment of benign lesions of vocal folds by means of ultrasonography.

OBJECTIVES: Although ultrasonography (US) has been widely used in various parts of the body, its application in laryngeal examination has been limited. Our objective was to evaluate the significance of US examination in benign lesions of the vocal folds. METHODS: Ultrasonographic examination of the vocal folds was performed in 14 patients in whom benign lesions of the vocal folds had been diagnosed by videolaryngoscopy and microlaryngoscopy. Microlaryngoscopic surgery was performed after US examination. Each lesion was analyzed for the following US features: shape, size, and echotexture (echogenicity and homogeneity). RESULTS: In total, 16 lesions were diagnosed in 14 patients by means of videolaryngoscopy and microlaryngoscopy. Ultrasonographic examination was capable of diagnosing 14 of the 16 lesions (87.25%). Ultrasonography mainly helped in the diagnosis of sessile polyps, nodules, and leukoplakia that were larger than 2 mm. The lesions were linear hyperechoic, heterogeneous hyperechoic, hypoechoic, and isoechoic if they were leukoplakia, nodules, hemorrhagic polyps, and other polypoid lesions, respectively. The results are better if the diagnosis follows the corresponding US echotexture pattern rather than videolaryngoscopy and microlaryngoscopy. CONCLUSIONS: Laryngeal US examination appears to be a useful diagnostic tool for supplementing microlaryngoscopy in the assessment of benign lesions of vocal folds. In contrast to these currently used imaging techniques, anesthesia is not necessary in laryngeal US examination. In addition, US is noninvasive, painless, and much less expensive than the other techniques.

Actinomycosis of the larynx.

Actinomycosis is a rare chronic granulomatous disease that involves the upper airway and gastrointestinal tract. Approximately 40-55% of actinomycosis comprises the cervicofacial form. It presents a challenging clinical diagnostic dilemma because of variable presentations in the head and neck. Herein, we report a rare case of actinomycosis presenting as a vocal cord nodule in a healthy 21-year-old man who was not immunocompromised and had no other known medical disease.
