Hiccups, also known as singultus, are spasmodic involuntary contractions of respiratory muscles that shorten respiration. The characteristic sound is caused by rapid closure of the glottis. In oriental medicine, the mechanism of hiccups is "reversed flow of Ki". Hiccups have been associated with neoplasm, infections, seizures, diabetes. renal failure, alcohol ingestion, various drugs, and ischemic events of the myocardium or central nervous system. We present a case of chronic hiccups after cerebral infarction that was successfully treated using moxibustion therapy.

Background and Objectives: As the laryngopharyngeal cancer is usually found at a advanced stage, it is difficult to get a wide surgical margin that preserves functional aspect and that is oncologically safe simultaneously. There were many operative technique to fulfill this principle, but none were satisfactory. Recently there were some reports about glottic and pharyngeal reconstruction using radial forearm free flap(RFFF) with palmaris longus tendon, which provided satisfactory oncologic and functional results. We attempted to perform this technique and to test usefulness at patients of laterally localized laryngopharyngeal tumor. Materials and Methods: Three patients were reconstructed glottis and pharynx using radial forearm free flap with palmaris longus tendon. Two hypopharyngeal cancer (T2N0M0) patients were performed wide vertical hemilaryngopharyngectomy and one supraglottic cancer(T2N0M0) patient was performed horizontovertical laryngopharyngectomy. Deglutitional function was evaluated with modified barium swallow and speech function was evaluated by speech pathologist. Results: Mean follow-up time was 29.3 months. There were no cancer recurrence. Their speech was satisfy-actory at social communication and oral feeding. They all have a complete oral nutrition from 26 days to 53 days. Decanulation time was from 71 days to 30 months. Conclusion: Glottic and pharyngeal reconstruction with radial forearm free flap could be accepted as a promising technique which offers a wide resection margin but satisfactory functional result in lateralized laryngohypopharyngeal cancer patients.

The patients with incomplete glottic closure have an important feature decreasing the maximum phonation time (MPT) because airflow rate or air leakage is greater than people without voice disorders. Also they can appear a problem in the intensity regulation. This study analyzed MPT difference based on the comfortable intensity and louder intensity and the correlation between MPT and respiration volume of unilateral vocal fold palsy (UVFP) and sulcus vocalis (SV) group. The twenty with UVFP, the 21 with SV, the 21 normal subjects measured MPT in /a/ vowel prolongation task with comfortable intensity and louder intensity and compared analysis by measuring FVC, $FEV_1$, $FEV_1/FVC$ to analyze the correlation between MPT and respiration volume. First, a comparison of MPT according to the intensity between groups is that MPT of the normal group was statistically significant long compared to the patient group in comfortable intensity, but MPT between groups was not statistically significant difference in the louder intensity. Second, an analysis of the correlation between MPT and respiration volume is that this was statistically significant correlation between MPT in comfortable intensity and MPT in louder intensity. But this did not show statistically significant correlation between intensity and respiration volume. This study can be supported the preceding study results deduced that shorting MPT of the patient group compared to the normal group was originated in the problem of laryngeal valving mechanism at the level of vocal folds rather than a problem of respiratory function. Also at the phonation by varying the intensity, the result can deduce that in the case of patient group, the length of MPT had been improved by increasing the glottal closure ratio in the louder intensity. These results can support the theoretical basis that should be applied to the clinicians by varying the intensity at the voice evaluation and voice therapy for the patients with the glottis incompetence.

Endoscopic laser cordectomy is known as an oncologically sound procedure for T1 and selected T2 glottic carcinoma ; it has comparable local control rate and better long-term laryngeal preservation rate when compared with those of radiotherapy. Even if results of the reported voice outcome studies after surgery or radiotherapy are diverse and controversial, resection deeper than the body layer of the vocal fold (type III, IV, V cordectomy) usually leads to aerodynamic insufficiency during phonation and results in poor voice quality. A keyhole defect or development of synechiae at the anterior commissure after type VI cordecomy may also result in unsatisfactory vocal outcome. However, many advances in phonosurgical techniques are reported to be successfully applied in the reconstruction of glottal defect that is subsequent to endoscopic laser cordectomy. In case of glottal insufficiency, voice restoration can be achieved by means of augmentation of the paraglottic space or medialization of the excavated vocal fold. Injection laryngoplasty with synthetic materials or autologous fat is gaining its popularity for restoring minor glottal volume defect because of its convenience. Laryngeal framework surgery, especially type I thyroplasty with premade implant systems or Gore-Tex, is most frequently used to correct larger glottic volume defect. In case of anterior commissural keyhole defect, additional procedure including laryngofissure may be required. For anterior commissural synechiae, laryngeal keel may be inserted for several weeks or mitomycin-C may be repeatedly applied after the division of adhesive scar to prevent restenosis. In this paper, current concepts and the authors' experiences of phonosurgical reconstruction of vocal function after endoscopic cordectomy will be introduced.

Hiccup is defined as an abrupt involuntary contraction of the diaphragm and intercostal muscles with sudden closure of the glottis 35 msec after onset. The term "intractable" is given to those hiccups with a duration ranging from 24 hours to more than 25 years. Short hiccup bouts are mostly associated with gastric distention or alcohol intake, resolved spontaneously or with simple remedies. In contrast, intractable hiccup is a rare but disabling condition which can induce depression, weight loss and sleep deprivation. Although the pathophysiologic mechanisms of hiccup are still poorly understood, wide variety of pathological conditions such as: brain tumor, abdominal tumor, myocardial infarction, renal failure, abdominal surgery etc., can cause intractable hiccup. A 58-year-old male who had suffered from hepatocellular cancer was consulted from medical department due to intractable hiccup. Initial treatment modalities with administrations of metoclopramide and chlorpromazine and nerve block including phrenic nerve block, cervical epidural block and glossopharyngeal nerve block were not effective. Administration of midazolam and baclofen however achieved desirable effect.

From simultaneous recordings of the external photoglottography, intra-oral air pressure (P_io), airflow and acoustic data from four native Seoul Korean speakers (2 male and 2 female), we have found that the two fricatives are not significantly different in glottal opening peak and airflow peak height either word-initially or word-medially and that the duration of aspiration is significantly reduced in word-medial /s/, compared to those in word-initial /s/, not in /s'/. We have also found that the duration of a high P_io plateau is significantly longer in /s/ than in /s'/ both word-initially and word-medially and that airflow resistance (R=P_io/U) at the onset and offset of a P_io plateau and at the time of airflow peak height is significantly higher in /s'/ than in /s/ across the contexts. However, the differences in P_io peak and F0 are not significant. In addition, the transition time to reach airflow peak height from the offset of a P_io plateau is found to be significantly longer in /s/ than /s'/ in both word-initial and word-medial positions. No significant differences in glottal opening peak and airflow peak height confirm that /s/ is specified as [-spread glottis] like /s'/. As for the other significant differences, we propose that /s/ is [-tense], and /s'/ [+tense].

Background: This study aimed to investigate the relationship between pharyngeal morphology and the success or failure of blind nasotracheal intubation using standard lateral cephalometric radiography and to analyze the measurement items affecting the difficulty of blind nasotracheal intubation. Methods: Assuming a line perpendicular to the Frankfort horizontal (FH) plane, the reference point (O) was selected 1 cm above the posterior-most end of the hard palate. A line passing through the reference point and parallel to the FH plane is defined as the X-axis, and a line passing through the reference point and perpendicular to the X-axis is defined as the Y-axis. The shortest length between the tip of the uvula and posterior pharyngeal wall (AW), shortest length between the base of the tongue and posterior pharyngeal wall (BW), and width of the glottis (CW) were measured. The midpoints of the lines representing each width are defined as points A, B, and C, and the X and Y coordinates of each point are obtained (AX, BX, CX, AY, BY, and CY). For each measurement, a t-test was performed to compare the tracheal intubation success and failure groups. A binomial logistic regression analysis was performed using clinically relevant items. Results: The items significantly affecting the success rate of blind nasotracheal intubation included the difference in X coordinates at points A and C (Odds ratio, 0.714; P-value, 0.024) and the ∠ABC (Odds ratio, 1.178; P-value, 0.016). Conclusion: Using binomial logistic regression analysis, we observed statistically significant differences in AX-CX and ∠ABC between the success group and the failure group.
