The laryngeal mound (LM) formed the caudal part of the pharyngeal floor, which varied in position, shape, and length at different ages. This work aimed to study the morphogenesis of the LM in the embryonic and post hatching periods grossly, histologically, and by scanning electron microscopy using forty-eight Japanese quails. The LM primordia appeared on the 8th day of incubation as a raised elevation carried on a deep median symmetrical sulcus (glottis primordium).

Purpose: This is a retrospective study to evaluate the results of surgical treatment of patients with pathological sulcus vocalis.
Methods: Thirty-six patients with pathological sulcus underwent surgery and in 33 cases were performed additional injection laryngoplasty. The pre- and postoperative evaluation of patients included the GRBAS scale, stroboscopic, and objective acoustic voice assessment.

Voice disorders can have major impact on quality of life. Problems caused by these disorders can be experienced in different domains. The Voice Handicap Index (VHI) is a well-known voice-related quality of life instrument to measure physical, emotional and functional complaints.

Among the difficult cases which phonosurgeons may encounter, the problem of vergetures is one of the most complex. The primum movens would seem to be a particular vocal fold lesion in the form of more or less pronounced ligament atrophy. About a retrospective study of 52 cases, the authors present their conclusions: This atrophy co-exists anatomically, with (a sometimes considerable amount of atrophied mucosa opposite, "glottal tension" clearly perceptible during surgery, especially along the lower edge); videostroboscopically, with (great vibratory rigidity, more or less severe glottal air-loss).

Objective: External vocal fold medialization thyroplasty is a standard technique for improving voice, swallowing and breathing impairments due to insufficient glottal closure caused by either unilateral vocal fold paralysis or deficit of vocal fold tissue (i.e. as a result of cordectomy, scarring processes or sulcus glottidis).
