“…However, CT must be performed to determine the level of preepiglottic space invasion for small infrahyoid epiglottic tumors planned to undergo laser operation. 8,15,16 Preepiglottic area involvement was 90% with CT in our study.…”

“…4,6,[12][13][14] Studies assessing the effectiveness of VLS in laryngial pathologies report that the diagnosis made by indirect laryngoscopy changes in 10% to 43% of cases after VLS evaluation. 4,7,8,12 Glottic closure, mucosal vibration of vocal cords, and nonvibratory segments can be evaluated by VLS. By enabling the determination of early stage larynx tumors, this method provides the chance for treatment with laser cordectomy or radiotherapy.…”

“…[6][7][8] The aim of the present study was to assess the accuracy of preoperative CT and endoscopic evaluation by comparing imaging and endoscopic findings of each modality with histopathologic examination results for each anatomical subsite in larynx cancer. The main goal was to determine the most efficient diagnostic tool in each anatomical region for staging in larynx cancer.…”

A AB BS ST TR RA AC CT T O Ob bj je ec ct ti iv ve e: : The aim of this study was to investigate which diagnostic method was more efficient and reliable for preoperative T staging of laryngeal cancers by comparing videolaryngostroboscopy (VLS) and computed tomography (CT) findings with histopathologic examination of operation specimens. The main goal was to determine the most rational and accurate approach for preoperative evaluation and staging of larynx cancers. M Ma at te er ri ia al l a an nd d M Me et th ho od ds s: : This retrospective study included 58 patients operated on for larynx cancer. Preoperative VLS and CT findings were compared with histopathologic examination results of the operation specimens. The larynx was divided into 12 anatomical areas for this purpose. In addition, thyroid and cricoid cartilage invasion and extralaryngeal invasion parameters were included in the evaluation. Invasion of the tumor was identified by each evaluation method separately. Mobility of the vocal cords and arytenoids was evaluated with VLS. R Re es su ul lt ts s: : CT was more effective than VLS in the evaluation of the paraglottic area, preepiglottic area, and subglottic area. CT was superior to VLS for the identification of thyroid involvement, cricoid cartilages and extralaryngeal invasion. VLS was more effective than CT for the assessment of the vocal cords and anterior commissure. Both diagnostic methods were effective for identification of tumor on the epiglottis. C Co on nc cl lu us si io on n: : Success of VLS and CT changes according to the involvement of different anatomic areas. A combination of VLS and CT together, while taking into consideration the location of the tumor, improves accurate staging and consequently the surgical success.K Ke ey y W Wo or rd ds s: : Laryngeal neoplasms; tomography, X-ray computed Ö ÖZ ZE ET T A Am ma aç ç: : Bu çalışmanın amacı, videolarengostroboskopi (VLS) ve bilgisayarlı tomografi (BT) bulgularını, operasyon materyallerinin histopatolojik değerlendirme sonuçlarıyla karşılaştırarak, larenks kanserlerinin preoperatif T evrelemesi için hangi tanısal yöntemin daha etkili ve güvenilir olduğunu araştırmaktı. Ana hedef, larenks kanserlerinin evrelemesi ve preoperatif değerlendirmesi için en akılcı ve doğru yaklaşımı saptamaktı. G Ge er re eç ç v ve e Y Yö ön nt te em ml le er r: : Bu prospektif çalışmaya larenks kanseri nedeniyle opere edilmiş 58 hasta dahil edildi. Preoperatif VLS ve BT bulguları, operasyon materyallerinin histopatolojik değerlendirme sonuçlarıyla karşılaştırıldı. Bu amaçla larenks 12 anatomik alana ayrıldı. Ek olarak tiroit ve krikoid kıkırdak invazyonu ve ekstralarengeal invazyon parametreleri değerlendirmeye dahil edildi. Tümör invazyonu her değerlendirme yöntemi ile ayrı ayrı tanımlandı. Vokal kordların ve aritenoidlerin mobilitesi VLS ile değerlendirildi. B Bu ul lg gu ul la ar r: : BT paraglotik alan, preepiglotik alan ve subglotik alan değerlendirmesinde VLS'den daha etkili bulundu.

“…The aim of this study was to determine the role of videorecorded FL (VFL) in evaluating the infant with airway distress. Although VFL and stroboscopy have been increasingly used with adults, 6–9 only a few select studies have used their capabilities in infants and children 10 , 11 . Compared with nonrecorded FL, VFL adds the benefit of repeated reviewing and analysis.…”

Accurate diagnosis of upper airway abnormalities by flexible laryngoscopy in infants is hampered by rapid laryngeal motion and lack of patient cooperation. This study evaluates the added role of videorecorded flexible laryngoscopy and the objective measurement of vocal fold abduction in improving the diagnosis of upper airway abnormalities in infants. Seventy-eight infants had videorecorded flexible laryngoscopy performed as part of their evaluation of a suspected airway disorder. These recordings were reviewed by three otolaryngologists for confirmation of the clinical diagnosis. From the video image, the maximum angle of vocal fold abduction was measured with image analysis software. Of 78 patients 40 had supraglottic or glottic abnormalities, 9 had nasal or nasopharyngeal obstruction, 9 had subglottic abnormalities (diagnosed subsequent to videolaryngoscopy), and 15 patients had normal findings on examination. Of those with laryngeal abnormalities, laryngomalacia was the most common diagnosis (23 of 78). Vocal fold paralysis was present in 4 patients. A separate group (9 of 78) of patients was identified as having symmetric bilateral limitation of vocal fold abduction. Laryngeal dyskinesia was diagnosed in these 9 patients. The mean values of maximal vocal fold abduction were as follows: (1) normals, 59.5 degrees; (2) laryngomalacia, 57.0 degrees; (3) paralysis, 26.6 degrees; and (4) incomplete abduction with laryngeal dyskinesia, 27.6 degrees. Videolaryngoscopy is a valuable tool for documentation, parent education, and analysis of infant laryngeal abnormalities. Repeat viewing of the video examination and frame-by-frame analysis improve the diagnostic accuracy. Using this approach, we have calculated the anterior glottic abduction angle in the normal and abnormal Infant larynx. In addition, we have identified a group of infants with incomplete abduction of the vocal folds that appears to be different from that found in vocal cord paralysis.
