Eagle syndrome is a rare condition caused by elongation of the styloid process or calcification of the stylohyoid ligament. Patients with Eagle syndrome typically present with dysphagia, dysphonia, cough, voice changes, otalgia, sore throat, facial pain, foreign body sensation, headache, vertigo, and neck pain. Here we report a case in which the patient initially presented with sore throat, left-sided facial pain, and cough. This case report provides a brief review of the diagnosis and nonsurgical management of this rare syndrome.

GRBAS(G : grade, R : rough, B : breathy, S : strained, A : asthenic) 음성장애평가는 성대의 이상 또는 말마비장애 등의 환자들을 평가하는 척도로 널리 사용된다. 하지만 사람에 의해 주관적인 평가로 이루어지는 방식의 문제점이 많이 제기되어, 자동화 알고리즘에 의한 객관적인 청지각적 음성장애 평가도구를 개발하려는 시도가 많이 연구되어왔다. 이러한 개발에 있어 보편적으로 선행되어야 하는 음소 분류 및 일치성 판단을 위한 객관적인 파라미터를 구하고자 함이 본 연구의 목적이다.

Voice therapy after post-thyroidectomy dysphonia is designed to improve glottal closure without supraglottic hyperfunction by development of abdominal support for breathing and intrinsic muscle strengthening exercises. Regarding voice therapy of unilateral vocal fold paresis/paralysis, several techniques such as head positioning, digital manipulation, pushing and pulling method are used for trial or temporary therapy. And the holistic voice therapy such as LSVT, Accent method, VFE are useful for hypofunctional voice disorders. These may be effective interventions as a temporary improvement until normal voice recovers or may provide the essentials for long-term rehabilitation.

Dysphonia is well known as one of the otolaryngological symptoms of coronavirus disease 2019 (COVID-19) infection. The vocal changes of the COVID-19 condition have been reported in terms of parameters of multi-dimensional voice assessment, including acoustic analysis, auditory-perceptual evaluation, and psychometric assessment. However, there has not been a daily followup study in patients with acute COVID-19 infection. In this study, a 41-year-old male performed daily voice recordings of vowel phonation and passage-reading tasks during the self-quarantine period of one week. Compared to the normal voice status of the prepandemic period, voice abnormalities peaked on day two after the diagnosis of COVID-19 infection and recovered after one week.

The purpose of this study was to use high-speed digital imaging (HSDI) to compare vocal vibratory behaviors of persons who stutter (PWS) and persons with muscle tension dysphonia (PMTD) for uttering the /i/ vowel in a bid to identify the characteristics of vocal fold vibratory behaviors of PWS. This study surveyed seven developmental PWSs and seven PMTDs. The findings of the study indicated the following: first, regarding the two groups' vocal fold vibratory behaviors, of seven PWSs, three were found to be close vocal tract (VC) and four were found to be combination vocal tract (VCB). Of the seven PMTDs, one was found to be VC, and the other six were found to be VCB. These results indicate that a voiceprint which is different from the open vocal tract (VO) found in normal groups in research conducted by Jung, et al. (2008b) appeared in both groups of this study. Even between the two groups, there is a difference in the voiceprint before vocalization. Second, a VKG analysis was conducted to identify the two groups' vocal cord contact quotient. As a result, the PWS group's vocal cord contact quotient changed gradually from an irregular one at the initial vocalization stage to a regular one. The PMTD group continued the tension at the initial vocalization. Putting together all of these results, there is a difference in vocal fold vibratory behaviors between PWSs and PMTDs when they speak. Thus, there was a difference in muscular tension between the two groups.

This study investigated the characteristics of two aerodynamic indices, PTP (Phonation threshold pressure) and PTF (Phonation threshold flow) in patients with ADSD (adductor spasmodic dysphonia) and to see if two new aerodynamic indices can differentiate between normal and ADSD group. Additionally, PTP and PTF values were compared in terms of overall severity of ADSD in the patient group. The severity of ADSD was rated on a 7-point rating scale by two experienced speech language pathologists. The Kay Elemetrics Phonatory Aerodynamic System (PAS) (Kay Elemetrics Corp., Lincoln Park, NJ) was used to collect PTP and PTF measurements from 16 female normal subjects, 31 female patients with ADSD. Significantly lower PTF values (P< 0.05) were observed in ADSD when compared to those of normal control. Also, significantly lower PTF values in severe ADSD patients (P<.001). However, PTP could not distinguish patients with ADSD from control groups (P=0.119) and among the ADSD groups according to the severity (P=0.177). Consequently, PTF was more sensitive than PTP which might differentiate between normal speakers and ADSD and among different levels of severity within ADSD, suggesting that PTF could be a useful diagnostic parameter to measure the aerodynamic function of ADSD and provide the neurolaryngeal dysfunction in patients with ADSD.

This study was investigate the usefulness of the DSI according to gender. The present study evaluated DSI in Korean population and Thirty voluntary participants (15 males, 15 females) who had G0 on the Grade, Roughness, Breathiness, Asthenics, Strain(GRBAS) and lived in Kyunggi-Do or Seoul, from March 2011 to June 2011. Maximum phonation time, the Highest fundamental frequency, the Lowest intensity, and Jitter(%) were measured using CSL 4500(Kay Pentax. USA). The experimenter explained the subjects the experimental condition and procedures and demonstrated the procedures, prior to the experiment. The result of in this study showed that the difference between males and females were not significants, although the Fhi was higher for females than for males. Therefore, We conclude that the DSI is a useful instrument to objectively measure the severity of dysphonia.
