An unusual cause of foreign-body sensation in the throat: corniculate cartilage subluxation

Relation between globus pharyngeus and OSA in patients examined simultaneously by PSG and pH monitor: A cross sectional study

OBJECTIVE

This was a first cross-sectional single-center study to research the relation between globus pharyngeus, OSA and GERD. Since previous clinical studies have demonstrated a relationship between globus phayrngeus and GERD, however, no reported study on the relation between globus pharyngeus, sleep disorders including OSA, and GERD.

METHODS

Seventeen patients underwent general and otorhinolaryngological examinations and responded to several questionnaires (ESS, PSQI, HADS, and Globus pharyngeus VAS score) at their first visit, and underwent a gastroesophageal test for 24-h pH monitoring and in-laboratory PSG one to two months later.

RESULTS

No significant differences were seen in ESS, PSQI, or HADS scores between the groups. The acid exposure time was not significantly different among the groups. The percentage of esophageal reflux time was higher than the percentage of laryngopharyngeal reflux time through the total time as well as the supine period. This indicated that GERD occurred more frequently than laryngopharyngeal reflux. The entire results showed concurrent OSA in 10 cases (59%) and concurrent GERD in 7 cases (41%). The cases with OSA were treated by CPAP or oral appliance, and those treatments were effective for globus pharyngeus.

CONCLUSION

Although the relation between OSA and globus phayngeus is still controversial, these findings suggest that OSA may be a previously undetected cause of globus pharyngeus. By improving OSA, it may offer an additional option of treatment for those globus pharyngeus cases combined with OSA.

The complexity of globus: a multidisciplinary perspective

Globus is a topic of interest for many specialties including otorhinolaryngology, gastroenterology and psychiatry/psychosomatic medicine, but, although many hypotheses have been suggested, key questions about its aetiology remain. This Review provides an overview of the extensive literature concerning this topic and discusses the quality of the evidence to date. Globus has been associated with oropharyngeal structural lesions, upper oesophageal sphincter disorders, oesophageal disorders, GERD, psychosocial factors and psychiatric comorbidity. However, findings are often contradictory and the literature remains highly inconclusive. Indeed, with the exception of patients with structural-based globus, the Rome III criteria for functional globus only apply to a subgroup of patients with idiopathic globus. In clinical reality, there exists a group of patients who present with idiopathic (nonstructural) globus, but nevertheless have dysphagia, odynophagia or GERD-exclusion criteria for globus diagnosis according to Rome III. The symptomatology of patients with globus might be broader than previously thought. It is therefore crucial to approach globus not from one single perspective, but from a multifactorial point of view, with focus on the coexistence and/or interactions of different mechanisms in globus pathogenesis. This approach could be translated to clinical practice by adopting a multidisciplinary method to patients presenting with globus.

[Paresthesias of the upper respiratory tract]

This review concerns the modern views of etiology, diagnostics, and treatment of the patients presenting with paresthesias of the upper respiratory tract. Various concepts of etiology of this pathology are described along with the relevant diagnostic and therapeutic approaches. Special attention is given to the debatable aspects of diagnostics and treatment of the patients complaining of the feeling of a lump in the throat ("globus sensation"). The opinions of the domestic and foreign authors concerning this problem are considered. The necessity of the search for the new additional therapeutic procedures for the treatment of paresthesias of the upper respiratory tract, including the non-medicamental modalities, is substantiated. It is concluded that the development of the new adequate diagnostic and therapeutic algorithm is indispensable for the enhancement of the effectiveness of the management of the patients with paresthesias of the upper respiratory tract and complaints of "globus sensation".

Management of globus pharyngeus

Globus pharyngeus is a common ENT condition. This paper reviews the current evidence on globus and gives a rational guide to the management of patients with globus. The aetiology of globus is still unclear though most ENT surgeons believe that reflux whether acidic or not plays a significant role. Though proton pump inhibitors are used extensively in practice, there is little evidence to support their efficacy. Most patients with globus can be discharged after simple office investigations. The role of pepsin-induced laryngeal injury is an exciting concept that needs further study. Given the benign nature of globus pharyngeus, in most cases, reassurance rather than treatment or extensive investigation with rigid oesophagoscopy or contrast swallows is all that is needed. We need more research into the aetiology of globus.

Do cervical degenerative diseases associate with foreign body sensation of the pharynx?

Foreign body sensation of the pharynx is a common complaint in otolaryngologic practice. The definite cause of this symptom is seldom precisely diagnosed, leading to chronic pharyngitis. The purpose of the present study was to evaluate the relationship between lump in throat and cervical degenerative disease by their clinical symptoms and the associated image characteristics. All patients with or without the complaint of lump in throat who attended the otolaryngologic clinics of Chang Gung Memorial Hospital-Kaohsiung Medical Center from January 2009 to May 2010 were prospectively eligible for this study. A total of 225 patients who met the inclusion criteria were assigned to either the study group (150 patients with symptoms of lump in the throat) or the control group (75 individuals without symptoms). All patients received plain views of the cervical lateral neck. The study group underwent further diagnostic examinations, including esophagography to exclude other diseases. Symptom scores (range, 0-3) and imaging characteristics such as the number (total spurs) and location (C level) of cervical osteophytes, interspace narrowing, spondylolisthesis, and retrolisthesis were compared between the two groups. It was found that the study group had a significantly greater number of total spurs (P < 0.001), and C45, C56, and C67 were the predominant sites, with significant odds ratios of more than 2 at all these levels. Only C67 revealed a difference in interspace narrowing, and only C45 showed a difference in spondylolisthesis between groups. Hence, a high correlation was found between the lump-in-throat sensation and total number of spurs, especially at the levels of C45, C56, and C67. This result implied that cervical osteophytes might be associated with foreign body sensations of the pharynx.

The morphometric development of the fetal larynx during the fetal period

OBJECTIVE

The aim of the present study was to investigate morphometric growth patterns of the cartilaginous components and vocal cords in human fetal larynx.

METHODS

This study was performed in the Anatomy Department of Meram Medicine Faculty in 2007. The fetuses were obtained from the Gynaecology Department of the Meram Medicine Faculty of Selcuk University, and Dr. Faruk Sükan Maternity Hospital (Konya, Turkey). Forty spontaneously aborted fetuses (25 males and 15 females) without detectable malformations were evaluated. The dimensions of the larynx and its cartilaginous components were measured and the relationship between the obtained data was statistically assessed with Student's t-test.

RESULTS

Correlations were found between the cartilaginous components, size of the larynx, and gestational age. No gender differences were identified. The anatomical variations in the epiglottis cartilage dimensions and types were found in 15% of cases. The foramen thyroideum was observed in 12.5% of cases.

CONCLUSION

The data of this study may contribute to the knowledge of the fetal larynx regarding laryngomalacia.
