Abstract
In clinical speech-language pathology practice, tongue force is usually evaluated qualitatively. Perception and practical experience are used to classify this force. The Biomechanical Engineering Group from the Federal University of Minas Gerais developed an instrument to quantify tongue force. The purposes of this study were to quantify maximum tongue protrusion force in Brazilian subjects with normal tongue strength and to compare force values between gender groups. In total, 105 subjects, 43 men and 62 women, aged from 18 to 29 years, with normal tongue strength according to qualitative evaluation, underwent quantitative evaluation by using the instrument. The mean of the maximum tongue force values of all participants was 17.58 ± 7.95 N. There were significant differences in the median values for maximum tongue forces between the genders, with higher values observed for men. In intersubject comparisons, high variation coefficients were evident due to the variability among individuals. However, the study suggested that the instrument could be an interesting tool for intrasubject comparisons, especially during the follow-up.

THE ESSENTIAL ROLE OF THE COM IN THE MANAGEMENT OF SLEEP-DISORDERED BREATHING: A LITERATURE REVIEW AND DISCUSSION.

Int J Orofacial Myology. 2014 Nov;40:42-55

Abstract
The origins of Orofacial Myofunctional Therapy began in the early 1960's by orthodontists who recognized the importance of functional nasal breathing, proper swallowing, and more ideal oral rest postures. Re-patterning these functions through myofunctional therapy assisted with better orthodontic outcomes and improved stability. Experts in orofacial myology have concluded that improper oral rest postures and tongue thrusting may be the result of hypertrophy of the lymphatic tissues in the upper airway. Orthodontists are aware of the deleterious effects these habits have on the developing face and dentition. Sleep disordered breathing is a major health concern that affects people from infancy into adulthood. Physicians who treat sleep disorders are now referring patients for orofacial myofunctional therapy. Researchers have concluded that removal of tonsils and adenoids, along with expansion orthodontics, may not fully resolve the upper airway issues that continue to plague patients' health. Sleep researchers report that the presence of mouth breathing, along with hypotonia of the orofacial muscular complex, has been a persistent problem in the treatment of sleep disordered breathing. Orofacial myofunctional disorders (OMDs) coexist in a large population of people with sleep disordered breathing and sleep apnea. Advances in 3D Cone Beam Computed Tomography (CBCT) imaging offer the dental and medical communities the opportunity to identify, assess, and treat patients with abnormal growth patterns. These undesirable changes in oral structures can involve the upper airway, as well as functional breathing, chewing and swallowing. Leading researchers have advocated a multidisciplinary team approach. Sleep physicians, otolaryngologists, dentists, myofunctional therapists, and other healthcare professionals are working together to achieve these goals. The authors have compiled research articles that support incorporating the necessary education on sleep disordered breathing for healthcare professionals seeking education in orofacial myology.

A REVIEW OF ELECTRICAL STIMULATION AND ITS EFFECT ON LINGUAL, LABIAL AND BUCCAL MUSCLE STRENGTH.

Int J Orofacial Myology. 2014 Nov;40:12-29

Authors: Safi MF, Wright-Harp W, Lucker JR, Payne JC, Harris O

Abstract
BACKGROUND: Lingual, labial and buccal weakness (LLBW) is a widespread consequence of several neurological insults. LLBW impact on oral motor functions such as speech production and swallowing is well documented in the literature. Therefore, it is important for the speech-language pathologists to have access to evidence-based approaches for treatment. Thus, it is imperative that the speech-language pathology field search for effective treatment approaches and explore new treatment modalities that can improve therapy outcomes. One relatively new modality in this field is neuromuscular electrical stimulation (NMES).
AIMS: The purpose of this paper is fivefold: (a) to provide an overview of the general effects of NMES on skeletal muscles; (b) to review the effect of NMES on orofacial musculature evaluating the potential appropriateness of NMES for use in strengthening lingual, labial and buccal muscles; (c) to identify future directions for research with consideration of its potential role in improving speech intelligibility and the oral preparatory phase of swallowing in patients with oral motor weakness; (d) to provide a brief anatomic and physiologic bases of LLBW; (e) to provide background information for orofacial myologists who may encounter individuals with LLBW.
MAIN CONTRIBUTION: NMES is a modality that is commonly used in physical therapy and occupational therapy fields that assists in treating several motor and sensory muscular disorders including muscular weakness. The literature reviewed demonstrate that very limited data related to the use of NMES on orofacial muscles exist despite the fact that these muscles can be easily accessed by electrical stimulation from the surface.
CONCLUSIONS: This review of the research using electrical stimulation of muscles highlights the need for experimental treatment studies that investigate the effect of NMES on orofacial weakness.

Medical therapy versus sinus surgery by using balloon sinus dilation technology: A prospective multicenter study.

Am J Rhinol Allergy. 2016 Jun 17;

Authors: Payne S, Stolovitzky P, Mehendale N, Brown W, Rieder A, Liepert D, Tseng E, Gould A, Powell S, Van Himbergen D, Karanfilov B, Harfe D, England L, Melroy C

Abstract
BACKGROUND: Although previous studies of sinus surgery that used balloon catheter dilation technology for the paranasal sinuses (balloon sinus dilation [BSD]) demonstrated safety and efficacy, data that compare BSD with continued medical management (MM) are lacking.
OBJECTIVE: To evaluate the outcomes of sinus surgery when using BSD instruments versus MM for patients with chronic rhinosinusitis for whom MM failed.
METHODS: Adult patients with chronic rhinosinusitis for whom a minimum of 3 weeks of oral antibiotics, 4 weeks of daily saline solution therapy, and 4 weeks of daily nasal corticosteroids failed were included. Qualifying participants were allowed to self-select sinus surgery with BSD (either an office or operating room setting) or continued MM. The primary end point was the comparison of change in the Chronic Sinusitis Survey score from baseline to 24 weeks. Secondary end points included comparisons of change for the Rhinosinusitis Disability Index (RSDI) and the Sino-Nasal Outcome Test (SNOT-20).
RESULTS: A total of 198 patients were enrolled (146 surgery and 52 MM). Of the patients who chose BSD, 72% (105/146) had their procedures completed in an office setting. Overall, BSD instruments were successful in dilating 97.6% of targeted sinuses (561/575). Patients who chose BSD showed a significantly greater improvement in the Chronic Sinusitis Survey score versus MM (42.0 versus 27.0, p < 0.001). Results from the RSDI and SNOT-20 surveys showed similar improvements for surgery versus MM (RSDI, 36.0 versus 18.1, p < 0.001; SNOT-20, 1.7 versus 1.0, p < 0.002).
CONCLUSION: Patients who selected sinus surgery in which BSD instruments were used on the peripheral sinuses demonstrated significantly greater improvements in quality of life compared with those who elected ongoing MM. These results were achieved through office-based procedures with the patient under local anesthesia in the majority of patients.

Outcomes of Transmastoid Surgery for Superior Semicircular Canal Dehiscence Syndrome.

Outcomes of Transmastoid Surgery for Superior Semicircular Canal Dehiscence Syndrome.

Otol Neurotol. 2016 Jun 20;

Authors: Powell HR, Khalil SS, Saeed SR

Abstract
OBJECTIVE: To present the management strategy and outcomes for our series of superior semicircular canal dehiscence syndrome (SSCDS) patients.
STUDY DESIGN: Retrospective cross-sectional study.
SETTING: Tertiary referral center.
PATIENTS: Thirty-seven consecutive patients referred from June 2011 to January 2015. Diagnosis of SSCDS based on presence of classical symptoms, computerized tomography, and concordant reduction in cervical vestibular evoked myogenic potentials.
INTERVENTIONS: Transmastoid resurfacing or plugging.
MAIN OUTCOME MEASURES: Pre- and postoperative pure tone audiometry. Nine item questionnaire grading pre- and postoperative symptom severity. Results of a short semi-structured telephone survey.
RESULTS: Twenty surgical patients: 13 women and 7 men. Mean age 52 years 6 months. Eighteen patients underwent transmastoid resurfacing and two underwent transmastoid plugging. Three of those who initially had resurfacing but had ongoing SSCD symptoms, subsequently had transmastoid plugging with complete resolution of third window symptoms. From the questionnaire there was improvement in mean scores for 8 of 9 of the SSCD symptoms, with statistically significant improvement in 6 of 9.
CONCLUSIONS: Management strategies and surgical techniques continue to evolve for SSCDS. We currently offer transmastoid resurfacing having informed patients of a 25% possibility of incomplete symptom resolution, and explain that plugging can be performed as a "second stage," if necessary. However, as we accrue more experience and there is more evidence from the literature we are considering whether to offer transmastoid plugging as our primary surgical procedure. In our experience, patients with multiple vestibular pathologies or atypical vestibular symptoms are the ones for whom SSCD surgery has not been curative, although they do report improvement in their SSCD symptoms.

Abstract
OBJECTIVE: The purpose of this study is to assess the effects of aging on air-conducted sound elicited cervical vestibular evoked myogenic potential (cVEMP) and ocular vestibular evoked myogenic potential(oVEMP) in normal people.
METHOD: Sixty normal subjects were recruited for the vestibular evoked myogenic potential examination. Among them, 20-40 year-old group was setted as the first group, 41-60 year-old group was setted as the second group, > 60-year-old group was setted as the third group. Each group included 20 normal subjects. SPSS 16.0 software was used to analyze the data.
RESULT: As the age growing, P1 latency prolonged, N1-P1 amplitude decreased, and amplitude asymmetric ratio increased in cVEMP; N1 latency prolonged, P1-N1 amplitude decreased, and amplitude asymmetric ratio increased in oVEMP.
CONCLUSION: With the age growing, the time of otolithic organ input pathways prolonged, the function of otolithic organ decreased and the decrease level may be asymeetrical on both sides.

[The roles of otolith organs in the recurrence primary benign paroxysmal positional vertigo].

Lin Chung Er Bi Yan Hou Tou Jing Wai Ke Za Zhi. 2015 Sep;29(18):1641-4

Authors: Zhou X, Yu Y, Wu Z, Liu X, Chen X

Abstract
OBJECTIVE: To explore the roles of otolith organs in the occurrence and recurrence of primary benign paroxysmal positional vertigo (BPPV) by vestibular evoked myogenic potential (VEMP) test.
METHOD: We enrolled 17 recurrent primary BPPV patients and 42 non-recurrent primary BPPV patients between September 2014 and November 2014. All patients underwent VEMP tests, including cervical vestibular evoked myogenic potential (cVEMP and ocular vestibular evoked myogenic potential (oVEMP) tests. The abnormal case was defined as non-elicitation or asymmetry rate between bilateral sides is larger than 29%.
RESULT: Significant difference was found in abnormal rate between cVEMP and oVEMP (P < 0.05 ) in BPPV patients. The abnormal rate of oVEMP was higher than that of cVEMP. Significant difference was found in abnormal rate in oVEMP test between recurrent and non-recurrent groups (P < 0.01) but not in cVEMP( P > 0.05). No significant difference was found in sex and age between recurrent and non-recurrent groups (P > 0.05).
CONCLUSION: The impairment of otolith organs, especially the utricle, is related to primary BPPV. Dysfunction of utricle may play a role in recurrence of BPPV. Recurrence of BPPV is not correlated with sex and age.

Authors: Zhang H, Li J, Guo P, Tian S, Li K

Abstract
OBJECTIVE: To observe the short and long-term efficacy of quick repositioning maneuver for posterior semicircular canal benign paroxysmal positional vertigo (PC-BPPV) in different age groups.
METHOD: The clinical data of 113 adult patients with single PC-BPPV who underwent quick repositioning maneuver from July 2009 to February 2015 were retrospectively analyzed. The quick repositioning maneuver was to roll the patient from involved side to healthy side in the coronal plane for 180° as quickly as possible. The patients were divided into 3 groups according to different ages: young group (< 45 years), middle-age group (45 ≤ age < 60 years) and old group (≥ 60 years). The short and long term outcomes of the three groups were observed.
RESULT: The left ear was involved in 58 cases (51.3%) and the right ear in 55 cases (48.7%). The short term improvement rates of the young, middle-age and the old groups were 92.5%, 93.6% and 92.3% respectively, and the long term improvement rate was 90.0%, 85.1% and 73.1% respectively. There was no significant difference among the three groups in short and long term outcomes (P > 0.05). The recurrence rate of the three groups was 5.0%, 6.4% and 15.4% respectively, also no significant difference (P > 0.05).
CONCLUSION: The quick repositioning maneuver along the coronal plane for PC-BPPV has a definite effect for every age groups. The method is simple, rapid and easy to master, and the patients are tolerated the maneuver well without evident side effect.

Surfactant proteins of the human larynx.

Surfactant proteins of the human larynx.

Ann Anat. 2016 Jun 17;

Authors: Sheats M, Schröder H, Rausch F, Bohr C, Kißlinger F, de Tristan J, Iro H, Garreis F, Paulsen F, Schicht M, Bräuer L

Abstract
PURPOSE: Surfactant proteins (SPs) originally identified in lung tissue are important players in the innate immune system. Beyond this, they contribute to stability and rheology of gaseous or aqueous interphases. In the present study, we determined the expression and presence of SPs (A, B, C and D) in different areas of the human larynx.
METHODS: mRNA expression of SP-A, -B, -C and -D was analyzed by means of RT-PCR in healthy samples of epiglottis, vocal and vestibular folds, subglottis and trachea. Distribution and localization of all four SPs were analyzed by Western blot and immunohistochemistry in healthy human tissue samples.
RESULTS: All four SPs were detected at the mRNA- and protein level in the human larynx as well as by means of immunohistochemistry in the different tissue samples of the human larynx.
CONCLUSION: The results reveal that all four SPs are produced with different expression patterns within the human larynx. Based on the known functions, our results suggest that SPs might be involved in maintaining mucus rheology and subsequently they could be essential components for proper phonation. Moreover, the proteins seem to play a role in immune defense of the larynx.

Head Neck Pathol. 2016 Jun 20;

Authors: Sproat R, Wong G, Rubin J

Abstract
A 55-year-old lady with a 6 month history of hoarse voice presented to our ENT department. Endoscopic examination displayed a white left arytenoid lesion. Biopsy of this lesion displayed a nodule covered with non-keratinizing stratified squamous epithelium, with a central core of polygonal cells, positive for S-100 staining. This confirmed a granular cell tumour. CO2 laser was utilised to excise this benign tumour. Granular cell tumours of the head and neck are common, but are infrequently found in the larynx. This case report highlights the importance for the otolaryngologist to be aware of this differential diagnosis, particularly as histologically they may be confused with squamous cell carcinoma.

Expression and localization of GPR99 in human nasal mucosa.

Auris Nasus Larynx. 2016 Jun 17;

Authors: Shirasaki H, Kanaizumi E, Himi T

Abstract
OBJECTIVE: The cysteinyl leukotrienes (CysLTs) are lipid mediators that have been implicated in the pathogenesis of allergic rhinitis. Pharmacological studies of CysLTs indicate that two classes of receptors, CysLT1R and CysLT2R exist. CysLT1R is a high affinity LTD4 receptor with lower affinity for LTC4, and a CysLT1R antagonist is currently used to treat asthma and allergic rhinitis. CysLT2R binds to LTC4 and LTD4 with equal affinity. GPR99 (also called GPR80), previously described as an oxoglutarate receptor (OXGR1), has recently emerged as a potential novel receptor with LTE4. The purpose of this study was to determine the expression and localization of GPR99 protein in the human nasal mucosa.
METHODS: Human turbinates were obtained after turbinectomy from 12 patients with nasal obstruction refractory to medical therapy. GPR99 protein expression was evaluated by western blotting, and the specific cells expressing GPR99 protein identified by immunostaining using a commercial anti-GPR99 (OXGR1) monoclonal antibody.
RESULTS: A 38-kDa band was detected in the western blots of human nasal samples by using the anti-GPR99 monoclonal antibody. We did not find any differences in GPR99 protein levels between allergic and non-allergic nasal mucosa. The immunohistochemical studies revealed that the anti-GPR99 monoclonal antibody mainly labeled vascular smooth muscle cells in the nasal mucosa.
CONCLUSION: These immunohistochemical results suggest that GPR99 may play some roles in the vascular response. Further functional studies will be necessary to clarify the biological significance of the GPR99 receptor in nasal vasculature.

Abstract
Laryngeal interarytenoid neurilemmomas (LIN) is a benign encapsulated tumor originating from the schwann cells lining nerve fibers. Even though LINs are extremely rare in incidence, they could present with potential threat to the airway and thus requiring prompt diagnosis and treatment. Here, we report two cases of LINs. Both patients underwent excision of the tumor via microlaryngeal endoscopic procedures and recovered well postoperatively without complications. No recurrence was observed postoperatively on routine follow-up after 14 months.
