Degree of hoarseness can be evaluated by judging the extent to which noise replaces harmonic structure in spectrogram a sustained vowel. However, this visual method is subjective. The present study was undertaken develop harmonics-to-noise (H/N) ratio as an objective and quantitative evaluation degree hoarseness. computation conceptually straightforward; 50 consecutive pitch periods vowel /a/ are averaged; H energy averaged waveform, while N mean differences between individual waveform....

Abstract Objective: The objective of this prospective study was to assess the long‐term effects immediate reconstruction recurrent laryngeal nerve (RLN) during thyroid cancer extirpation on postoperative phonatory function. Subjects and Methods: subjects were 22 patients with advanced who underwent resection primary lesion involved RLN. RLN paralysis seen in 12 preoperatively involvement noted intraoperatively 10. Immediate performed eight using great auricular one direct anastomosis stumps...

Although numerous causative genes for hereditary hearing loss have been identified, there are no fundamental treatments this condition. Herein, we describe a novel potential treatment genetic loss. Because mutations or deletions in the connexin (Cx) common causes of profound congenital both humans and mice, investigated whether gene supplementation therapy using wild-type Cx could cure We first generated inner ear-specific 30 (Cx30)-deficient mice via transuterine transfer Cx30-targeted...

Objectives: To describe a new technique of nervemuscle pedicle (NMP) flap implantation combined with arytenoid adduction (AA) to treat dysphonia due unilateral vocal fold paralysis and examine postoperative function.Study Design: Retrospective review clinical records.Setting:

Objectives Standard treatments of adductor spasmodic dysphonia (AdSD) provide temporary relief symptoms. Type 2 thyroplasty offers a long‐term solution; however, voice outcome data are lacking. The objective this study was to assess the outcomes type with titanium bridges through use validated questionnaire. Study Design Case series chart review. Setting University hospital. Subjects and Methods Forty‐seven consecutively enrolled patients AdSD underwent between August 2006 November 2014....

We examined the frequency of p53 mutations in 38 oropharyngeal squamous cell carcinomas (SCC), using both a yeast functional assay and conventional immunohistochemical staining method (IHC) to detect mutations.We also explored clinical importance SCC. An accumulation protein was detected 17 (45%) tumors by IHC, whereas yeast-based 6 additional mutations, for total 23 (61%) with mutations. The cDNA sequencing analysis revealed that undetected IHC consisted 3 frameshift, 1 nonsense 2 missense...

We describe the technique of decompression facial nerve from geniculate ganglion to stylomastoid foramen. The was made on 51 patients with Bell's palsy, and results follow-up study were compared those 77 in whom pyramidal vertical segments decompressed. decompressions indicated when a severe denervation confirmed by electrodiagnostic examinations. Incidences notable residual palsy pronounced sequelae always lower former group regardless operational timing. In either group, more desirable...

As the degree of judged hoarseness increases, noise component appears to a greater and replaces harmonic structure in spectrogram. The relationship between these two components has been quantified as harmonics (H/N) ratio. computation is straightforward; 50 consecutive pitch periods sustained vowel /a/ are averaged; H energy average waveform, while N mean differences individual waveform. Therefore, H/N ratio could be measured clinic with aid small, inexpensive computer. This was successfully...

Unilateral vocal fold paralysis (UVFP) is one of the most serious problems in conducting surgery for thyroid cancer. Different treatments are available management UVFP including intracordal injection, type I thyroplasty, arytenoid adduction, and laryngeal reinnervations. The effects immediate recurrent nerve (RLN) reconstruction during cancer with or without before were evaluated videostroboscopic, aerodynamic, perceptual analyses. All subjects experienced postoperative improvements voice...

Of 625 patients with Bell's palsy, 26 from 25 families (4.0%) had a positive family history of palsy. Genealogic analysis the indicated mode inheritance familial palsy possibly to be autosomal dominant low penetration. The prognosis was generally favorable. Age, sex, recurrence, and inherited factors are discussed.

Invasive aspergillosis of the paranasal sinuses involving orbit is termed sino-orbital aspergillosis. Prognosis aspergillosis, complicated by impaired visual acuity and neurological signs, disastrous usually fatal. We herein report two patients with associated total ophthalmoplegia. One patient was successfully treated surgical eradication including orbital exenteration. In contrast, other died cerebral infarction, probably due to fungal thrombosis middle artery, despite repeated local...

Objectives/Hypothesis To measure the swallowing pressure (SP) of normal subjects using a 2.64‐mm‐diameter high‐resolution manometry (HRM) catheter with 36 circumferential sensors. Study Design Repeated measures serving as controls. Methods Thirty healthy swallowed water at different temperatures and volumes to examine maximum SP velopharynx, meso‐hypopharynx, upper esophageal sphincter (UES), cervical esophagus, duration lowered UES. Results The any location was unaffected by volume water,...

Fifteen patients suffering from visual disturbance of varying degrees caused by a mucocele the posterior ethmoid and/or sphenoid sinuses underwent marsupialization into nasal cavity. Five eight with severe loss worse than 20/200 showed recovery measurable vision. Two these five were operated on within 24 hours after onset and marked to 20/25 20/15. The other seven who had relatively mild experienced improvement acuity or remission subjective complaints such as blurred vision...

The aim of this study was to document the usefulness endoscopic endonasal approach as a surgical treatment isolated blowout fractures orbital floor.Retrospective study.Between 1997 and 2003, using only an approach, we operated on 62 patients complaining diplopia due floor. In order perform reduction surgery, supplemental septoplasty and/or submucous conchotomy were done. Immediately following fixation, eye traction tests performed confirm ocular motility improvement. Tampon gauzes or balloon...

Abstract Objectives/Hypothesis: To determine the effects of long‐term denervation on rat thyroarytenoid (TA) muscle and neuromuscular junctions. Study Design: A quantitative histologic assessment TA after denervation. Methods: Thirty Wistar rats were euthanized 10, 18, 26, 42, 58 weeks left recurrent laryngeal nerve resection. The areas entire individual fibers evaluated using hematoxylin‐eosin staining, junctions detected by immunohistochemistry. Changes comparing treated (T) untreated (U)...

Type II thyroplasty, or laryngeal framework surgery, is based on the hypothesis that effect of adductor spasmodic dysphonia (AdSD) voice due to excessively tight closure glottis, hampering phonation. Most previous, partially effective treatments have aimed relieve this closure, including recurrent nerve section avulsion, extirpation muscle, and botulinum toxin injection, which currently most popular. The aim study was assess effects type thyroplasty aerodynamic acoustic findings in patients...
