Authors: Topaloğlu İlhan , Koçak İsmail , Saltürk Ziya 
Published: October 2014

Objectives: The aim of this study was to assess the vocal outcome and the impact of arytenoid resection on vocal function following supracricoid laryngectomy with cricohyoidopexy. Methods: Twenty-eight male patients who had undergone supracricoid laryngectomy with cricohyoidopexy were included in the study. In 7 patients, one arytenoid cartilage had been totally resected; in 11, both arytenoid cartilages had been preserved; and in 10, one arytenoid cartilage had been partially resected. The maximum phonation time, fundamental frequency, jitter, shimmer, and noise-to-harmonics ratio were assessed and analyzed. Perceptual analysis was performed with the grade, roughness, breathiness, asthenia, and strain (GRBAS) scale. Abduction-adduction and anteroposterior squeezing actions were analyzed from videoendoscopic records. The Voice Handicap Index–10 (VHI-10) was used for self-assessment. Results: The acoustic and aerodynamic parameters and GRBAS score showed severe impairment. The self-assessment revealed that patients were relatively satisfied with their voice quality. There were no statistically significant differences in the acoustic and aerodynamic parameters, the GRBAS score, or the VHI-10 score according to the level of arytenoid resection. Conclusions: Supracricoid laryngectomy with cricohyoidopexy caused deterioration of acoustic and aerodynamic voice parameters and the GRBAS score. Statistically, the level of arytenoid resection had no apparent effect on the objective, perceptual, or subjective voice parameters.

Objectives: To investigate the biological factors related to the onset of Bell's palsy, we sought to identify differentially expressed genes in peripheral blood mononuclear cells (PBMCs) and plasma of patients with Bell's palsy and Ramsay Hunt syndrome (RHS). Methods: We carried out DNA microarray analyses using PBMCs taken from patients with Bell's palsy at their initial visit and 2 to 4 weeks later. To validate these analyses, we measured the relative messenger RNA levels of α-defensin in paired PBMCs by reverse transcription–polymerase chain reaction. The plasma concentrations of α-defensin in patients and healthy volunteers were quantified by enzyme-linked immunosorbent assay. Results: The DNA microarray analysis identified α-defensin as a candidate gene related to the onset of Bell's palsy. Reverse transcription–polymerase chain reaction analysis showed that the relative α-defensin messenger RNA levels in PBMCs from the later visit were increased at least twofold in 9 of 13 patients (69%) with Bell's palsy and in 4 of 6 patients (67%) with RHS. The plasma α-defensin concentrations in the patients with RHS were significantly higher than those in healthy volunteers (p = 0.0013) and in the patients with Bell's palsy (p = 0.0306). Elevations of plasma α-defensin were observed in 5 of the 9 patients with Bell's palsy who demonstrated α-defensin overexpression in PBMCs. Conclusions: α-Defensin may be one of the biological factors related to the onset of Bell's palsy and RHS.

Authors: Holmes Samantha R. M. , Gudridge Tricia A. , Gaudiani Jennifer L. , Mehler Philip S. 
Published: October 2014

Objectives: In severe anorexia nervosa, there are a litany of medical complications that affect virtually every body system, and severe weakness is a typical characteristic. To our knowledge, aspiration risk, dysphagia recognition, and dysphagia management and intervention have not been well described in the literature in regard to severe anorexia nervosa. The purpose of this case series is to increase awareness among clinicians of possible oropharyngeal dysphagia symptoms that may present in patients with severe anorexia nervosa. Methods: We describe the cases of 3 patients with severe anorexia nervosa who presented with symptoms of dysphagia. The speech-language pathology team administered dysphagia therapy to the 3 patients utilizing neuromuscular electrical stimulation (NMES) in conjunction with swallowing therapy tasks that included strengthening exercises and compensatory strategies. Results: After the course of dysphagia treatment intervention, the 3 patients were able to tolerate an oral diet with improved swallowing function and no ongoing aspiration. Conclusions: The use of NMES in conjunction with traditional swallowing exercises in the treatment of dysphagia in patients with anorexia nervosa may reduce the need for enteral feeding and prolonged hospitalization. In regard to dysphagia intervention and management within this population and across other populations, rigorous randomized controlled studies are necessary for determining the efficacy of NMES and traditional swallowing therapy implementation.
Cross-Sectional Vestibular Nerve Analysis in Vestibular Neuritis
Authors: Fundakowski Christopher E. , Anderson Joshua , Angeli Simon 
Published: October 2014

Objectives: We examined the association between the size and cross-sectional area of the superior vestibular nerve as measured on constructive interference in steady-state (CISS) parasagittal magnetic resonance imaging (MRI) and the vestibular nerve function as measured by electronystagmography. Methods: The retrospective observational cohort study took place at an academic tertiary referral center. Twenty-six patients who met established clinical and electronystagmographic criteria for vestibular neuritis and who underwent parasagittal CISS MRI were identified. Two blinded investigators measured vestibular nerve height and width bilaterally at the level of the fundus of the internal auditory canal and calculated the cross-sectional nerve areas. The inter-rater reliability and agreement were analyzed. Symptom duration, age, and gender were also examined. Results: A statistically significant decrease was observed in both vestibular nerve cross-sectional area and height as compared to the contralateral vestibular nerve. A non–statistically significant trend was observed for a relative decreased cross-sectional nerve area with increased age, as well as a decrease in nerve area with an increase in symptom duration. Conclusions: Decreases in both vestibular nerve cross-sectional area and height are observed in patients with unilateral vestibular neuritis as measured on parasagittal CISS MRI.

Authors: Guinand Nils , Boselie Frans , Guyot Jean-Philippe , Kingma Herman 
Published: October 2014

Objectives: Currently, there is no evidence of an effective treatment for patients with bilateral vestibulopathy (BV). Their main complaints are oscillopsia and imbalance. Opinions about the impact of BV on their quality of life are controversial, and their handicap is not always recognized, even among otoneurologists. The aim of this study was to objectively assess the health status of BV patients in order to evaluate the need for pursuing efforts toward the development of new treatments. Methods: The Short-Form Health Survey (SF-36), the Dizziness Handicap Inventory (DHI), the Short Falls Efficacy Scale–International (Short FES-I), and an oscillopsia severity questionnaire were submitted to 39 BV patients. The SF-36 scores were compared to the scores of a general Dutch population. The DHI scores were correlated to the oscillopsia severity scores. The Short FES-I scores were compared to scores in an elderly population. Residual otolithic function was correlated to all scores, and hearing to SF-36 scores. Results: Compared to the general Dutch population, the BV patients scored significantly worse on the “physical functioning,” “role physical,” “general health,” “vitality,” and “social functioning” SF-36 variables (p < 0.05). The DHI scores were strongly correlated with the oscillopsia severity scores (r = 0.75; p < 0.000001). The Short FES-I scores indicated a slight to moderate increase in the patients' fear of falling. No significant score differences were found between BV patients with residual otolithic function and patients with complete BV. There was no correlation between hearing status and SF-36 scores. Conclusions: The results correlate with our clinical impression that BV has a strong negative impact on physical and social functioning, leading to a quality-of-life deterioration. There is a clear need for a therapeutic solution. Efforts toward the development of a vestibular implant are justified.
Voice Outcomes following the Gray Minithyrotomy
Authors: Mallur Pavan S. , Gartner-Schmidt Jacqueline , Rosen Clark A. 
Published: October 2014

Objectives: Most practitioners have limited treatment options for vocal fold scar and sulcus vocalis. The Gray minithyrotomy (GMT) is a surgical procedure for the treatment of these conditions, although limited objective data exist regarding voice outcomes. This study compares the quantified subjective and visual perceptual outcomes following GMT for the treatment of vocal fold scar and sulcus vocalis. Methods: We performed a retrospective review of patients who underwent GMT in a single institution. Patient-reported satisfaction, Voice Handicap Index–10 scores, results of video perceptual analysis, and complications were recorded. Results: Sixteen patients underwent GMT for phonotraumatic or postoperative scar (11), radiation-induced scar (3), or sulcus vocalis (2). Seven underwent bilateral operations. Follow-up data were available for 12 patients. Eight patients had 2 or more failed surgical interventions before GMT. Seven of the 13 procedures resulted in a self-reported improvement. Although the mean preoperative Voice Handicap Index–10 score (30.6) across all patients did not decrease after the operation, 6 of the 13 GMT procedures resulted in improvement (mean decrease, 7.5). Complications, encountered in 5 patients, included ecchymosis, neck abscess, tongue numbness, wound dehiscence, and aspiration pneumonia. Conclusions: The GMT is a viable treatment for severe vocal fold scar and sulcus vocalis. Our results show improvement in half of a cohort that was marked by previous failures at improving voice. These results point to the recalcitrant nature of voice difficulties in treating vocal fold scar and sulcus, and may properly guide clinicians and patients in their expectations following this infrequently used technique.

Published: October 2014

Objectives: We describe our experience in the reconstruction of large 3-layer lip defects using free revascularized lower-arm and fibula flaps. Methods: Between 2005 and 2009, nine patients underwent free-flap reconstruction after oncological surgery involving the lip and chin with or without mandibular involvement. The flap techniques are described, and postoperative functional and aesthetic results were recorded. Results: There were no flap failures. All patients showed intact oral function and good aesthetic results. Two patients died of distant metastases, 8 months and 17 months after surgery. Conclusions: Three-layer defects of the lip ideally require free-flap reconstruction, which has a high probability of achieving good functional and aesthetic results.
Middle Ear Effusion and Fungi
Authors: Murakami Atsushi , Tutumi Takesi , Watanabe Kensuke 
Published: October 2014

Objectives: Bacteria and viruses are rarely isolated from the middle ear fluid in cases of otitis media with effusion (OME). However, since endotoxins are often detected in such effusions, it is suspected that patients with OME have a previous history of gram-negative infection. Recently, fungi have drawn attention as microorganisms that cause chronic sinusitis. We investigated the involvement of fungi in the formation of middle ear effusions of patients with OME and eosinophilic otitis media, in which patients have viscous middle ear effusions and a history of adult bronchial asthma indicating definite involvement of eosinophils. Methods: Middle ear effusions and nasal secretions were collected from patients with eosinophilic otitis media (7 patients) or OME (12 patients), and smears were prepared for methenamine silver staining. The remaining specimens were embedded in Epon and stained with toluidine blue for observation under a light microscope, and ultrathin sections were prepared for examination under an electron microscope. Results: Fungal hyphae were detected in the middle ear fluid in all of the patients with eosinophilic otitis media or OME. Charcot-Leyden crystals (CLCs) were observed in 6 of the 7 patients with eosinophilic otitis media. In regard to the findings in the nasal secretions, fungal hyphae were also detected in the nasal secretions of all patients, whereas CLCs were detected in only 1 patient with eosinophilic otitis media. Conclusions: It was clarified by use of the methenamine silver staining method that fungi were present in the middle ear fluid in 100% of the studied cases of eosinophilic otitis media or OME. Whether fungi are also present in the middle ear cavity of normal persons is unknown, but the possibility that they may contribute as a cause of both diseases cannot be excluded. Particularly in eosinophilic otitis media, the observation of numerous CLCs in the middle ear fluid suggests that many eosinophils have degenerated. The eosinophil granule proteins released from the degenerated eosinophils can cause epithelial injury of the middle ear. The possibility that fungi induce the eosinophils in the middle ear also cannot be excluded.

Published: October 2014

Objectives: We assessed the use of transoral robot-assisted lingual tonsillectomy and uvulopalatopharyngoplasty for the surgical management of tongue base obstruction in patients with obstructive sleep apnea. Methods: In a prospective, nonrandomized trial using historical controls, patients underwent drug-induced sleep endoscopy, transoral robot-assisted lingual tonsillectomy with uvulopalatopharyngoplasty, and preoperative and postoperative polysomnography. Results: Twenty patients have completed the study to date. The rate of surgical success was 45%, and the rate of surgical response was 65%. The mean preoperative apnea-hypopnea index of 55.6 decreased by 56.7%, to a mean postoperative value of 24.1 (p < 0.001), and the minimum arterial oxygen saturation increased from the mean preoperative value of 75.8% to the mean postoperative value of 81.7% (p = 0.013). The mean Epworth Sleepiness Scale score improved from 13.4 to 5.9 (p = 0.003). One patient had postoperative bleeding that required cauterization, resulting in a major complication rate of 4.2%. Conclusions: Transoral robot-assisted lingual tonsillectomy with uvulopalatopharyngoplasty is a novel technique for the surgical management of obstructive sleep apnea that results in a significant decrease in the apnea-hypopnea index, a significant improvement in minimum arterial oxygen saturation, and a significant improvement in the Epworth Sleepiness Scale score and has an acceptable complication rate.
Selective Vestibular Neurolabyrinthitis of the Lateral and Superior Semicircular Canal Ampulla and Ampullary Nerves
Authors: Magliulo Giuseppe , Gagliardi Silvia , Appiani Mario Ciniglio , Iannella Giannicola , Gagliardi Mario 
Published: October 2014

Objectives: The diagnosis of vestibular neurolabyrinthitis is based on the sudden appearance of vertigo that lasts for hours or days without associated cochlear or central nervous system signs or symptoms. The advent of the video head impulse test, cervical vestibular evoked myogenic potential testing, and ocular vestibular evoked myogenic potential testing has provided interesting clinical evidence for evaluating and monitoring the damage to specific compartments of the vestibular apparatus. These various methods of testing individual end-organ functions may have a clinical impact on the vestibular workup of neurolabyrinthitis. Methods: This report describes 3 patients with acute vestibular neurolabyrinthitis in whom caloric tests, cervical vestibular evoked myogenic potentials, ocular vestibular evoked myogenic potentials, and the video head impulse test led to a suspicion of peripheral vestibular deficits of the lateral or superior semicircular canal ampulla or ampullary nerves. Results: In our patients, the examination results (normal hearing, absence of responses on caloric testing, and bilateral preservation of cervical and ocular vestibular evoked myogenic potentials) disclosed an acute partial superior vestibular neurolabyrinthitis. Conclusions: To our knowledge, these are the first reported cases in which selective damage to the lateral and superior semicircular canals and their nerves caused by neurolabyrinthitis was demonstrated clinically. Our clinical results indicate that the damage can be selective for specific vestibular end organs.
Oral Frostbite Due to Dry Ice
Authors: Ohki Masafumi , Ishikawa Jyunichi , Kikuchi Shigeru 
Published: October 2014

Objectives: Dry ice is a commercially available cryogen that is used worldwide. It may cause frostbite if misused. However, frostbite of the oral cavity due to dry ice has not been previously reported. Here, we describe the first case of dry ice–induced frostbite of the oral cavity. Methods: We present a case of oral frostbite due to dry ice and subsequent swelling of the submandibular area and lower lip. We discuss the clinical features of oral frostbite due to volatile substance abuse. Results: Oral frostbite not only may result in the impairment of the affected mucosae directly, but also may adversely affect the tissues in the vicinity of the oral cavity floor indirectly. Oral frostbite may cause edema of the upper airway tract. In case of severe pharyngolaryngeal edema, either tracheal intubation or tracheostomy is necessary. Steroids and antibiotics may be effective in preventing the development of pharyngolaryngeal edema. Conclusions: It is important to bear in mind that volatile substance abuse may possibly induce unusual events. In particular, special attention should be paid to delayed unusual events.

Published: October 2014

Objectives: This study aimed to determine whether computed tomographic (CT) scans on which foreign body impaction cannot be detected can be relied upon to decide whether a patient requires further investigation by esophagoscopy. This information might minimize unnecessary esophagoscopy without incurring the risk of a missed impacted foreign body. Methods: In a retrospective chart review of all patients admitted to National University Hospital, Singapore, over the period 2004 to 2011 for an ingested foreign body, case files of patients who underwent preoperative CT scanning followed by esophagoscopy were identified and reviewed. The results of the CT scan and the findings of esophagoscopy in these patients were analyzed. Results: A total of 376 patients underwent rigid esophagoscopy for an ingested foreign body during this period. Of these, 119 patients had CT scans performed before the endoscopy. Based on our analysis, the sensitivity of CT scanning was 100%, and the specificity was 70.6%. The positive predictive value was 89.5%, and the negative predictive value was 100%. None of the patients who had CT scans with no detectable foreign body had complications on follow-up. Conclusions: CT scanning appeared to be sensitive and specific in investigation of patients with an ingested foreign body. It also has a high negative predictive value, which may allow it to be the only preliminary investigation in these patients. Based on these data, a prospective study with close monitoring of patients who have CT scans with no detectable foreign body can be designed to accrue more patients to answer this query.

Published: October 2014

Objectives: In this study, we set out to assess the association of postoperative pain types with the risk of hemorrhage after tonsillectomy. Methods: The questionnaire-based study was conducted on 335 patients who had undergone tonsillectomy. Hemorrhage risk and postoperative pain were evaluated retrospectively with use of a visual analog scale for 5 time periods (day 1, days 2 to 3, days 4 to 7, days 7 to 14, and later). Results: Five pain types were identified by a cluster analysis. The most frequent pain types, I (24.8%; 83 patients) and II (50.8%; 170 patients), show decreasing pain, with pain type II starting on a higher level than pain type I. Pain types III (10.7%; 36 patients) and IV (1.2%; 4 patients) start at a low level with increasing pain for the first few days. In type III, pain decreases after 1 week, whereas type IV consists of a high level of pain for more than 2 weeks. Pain type V (12.5%; 42 patients) involves a very high level of pain from the beginning, which decreases only gradually. Pain type I is associated with a low hemorrhage rate. Patients with increasing pain (types III and IV) and pain type V show a significantly higher hemorrhage risk. Conclusions: Patients who have severe or increasing pain in the first few days after tonsillectomy have a significantly higher risk of hemorrhage.

Authors: Gfeller Kate , Turner Christopher , Oleson Jacob , Kliethermes Stephanie , Driscoll Virginia 
Published: October 2014

Objectives: This study examined speech recognition abilities of cochlear implant (CI) recipients in the spectrally complex listening condition of 3 contrasting types of background music, and compared performance based upon listener groups: CI recipients using conventional long-electrode devices, Hybrid CI recipients (acoustic plus electric stimulation), and normal-hearing adults. Methods: We tested 154 long-electrode CI recipients using varied devices and strategies, 21 Hybrid CI recipients, and 49 normal-hearing adults on closed-set recognition of spondees presented in 3 contrasting forms of background music (piano solo, large symphony orchestra, vocal solo with small combo accompaniment) in an adaptive test. Outcomes: Signal-to-noise ratio thresholds for speech in music were examined in relation to measures of speech recognition in background noise and multitalker babble, pitch perception, and music experience. Results: The signal-to-noise ratio thresholds for speech in music varied as a function of category of background music, group membership (long-electrode, Hybrid, normal-hearing), and age. The thresholds for speech in background music were significantly correlated with measures of pitch perception and thresholds for speech in background noise; auditory status was an important predictor. Conclusions: Evidence suggests that speech reception thresholds in background music change as a function of listener age (with more advanced age being detrimental), structural characteristics of different types of music, and hearing status (residual hearing). These findings have implications for everyday listening conditions such as communicating in social or commercial situations in which there is background music.
