Introduction: The distance between the anterior commissure of the larynx and the first tracheal ring (AC.T. distance) is of great importance in laryngotracheal surgeries.  The amount of narrowing of the subglottic airway is used as a quantitative mean to determine whether the lesion is subglottic or has extended to the trachea and therefore helps in the prediction of the final prognosis.   Mate...

OBJECTIVE The anterior commissure (AC) and posterior commissure (PC) are the two distinct anatomic structures in the brain which are difficult to observe in detail with conventional MRI, such as a 1.5T MRI system. However, recent advances in ultra-high resolution MRI have enabled us to examine the AC and PC directly. The objective of the present study is to standardize the shape and size of the...

BACKGROUND Early glottic cancer can be cured with transoral laser resection, but in cases with anterior commissure involvement, there is still controversy concerning the best treatment modality. METHODS The impact of anterior commissure involvement on local control was analyzed in a retrospective review of 444 patients with early glottic cancer (pT1a-pT2a) treated between 1986 and 2004 with t...

A 53-year-old man with severe vocal fold atrophy underwent bilateral type 1 thyroplasty and anterior commissure advancement. Postoperatively, he developed a strained voice with less projection and volume than prior to surgery. This was verified by objective assessment of vocal function. Videoendoscopy revealed bilateral false vocal fold fullness and blunting of the anterior commissure. Magnetic...

The anterior commissure defect of tricuspid valve may leave remnant regurgitation with inadequate leaflet coaptation after simple patch closure of the defect. A 19-year-old man underwent commissuroplasty for the anterior commissure defect caused by tricuspid valve endocarditis. Significant remnant regurgitation after patch closure of the anterior commissure defect was successfully solved by mod...

OBJECTIVES In this study preoperative examination, computed tomography and the peroperative macroscopic examination of the specimen were compared in the determination of anterior commissural involvement in laryngeal cancer. PATIENTS AND METHODS Twenty-two male patients (mean age 59.6 ± 9.9 years; range 46 to 78 years) who underwent total laryngectomy for laryngeal cancer between January 2007 ...
