The laryngeal cavity is shaped like an hourglass, composed of the laryngeal vestibule above the vestibular folds (false vocal folds), and the infraglottic cavity inferior to the vocal folds (which include the vocal ligaments) (Plate 3.44). The vestibular fold and the vocal fold (true vocal fold) are separated by a space called the laryngeal ventricle, which is quite variable in extent. The glottis includes the vocal folds and the space between them, which is designated the rima glottidis.

The vestibular folds are thick folds of mucous membrane scaffolded on a narrow band of fibrous tissue, the vestibular ligament, which is the lower border of the upper quadrilateral membrane. It is fixed in front at the angle of the thyroid cartilage just below the attachment of the epiglottic cartilages and behind the anterolateral surface of the arytenoid cartilage just above the vocal process (see Figure 58.7).
Clinical application of a curved video suspension laryngoscope in laryngeal surgery

In addition, the design of the curved video SL system significantly reduced the lifting force required to completely expose the glottis, which facilitated the complete removal of vocal cold lesions. Difficult laryngeal exposure is a challenging clinical situation and a leading cause of operation termination in phonomicrosurgery in conventional SL [17]. Our curved video SL design potentially overcomes this problem. Among 185 patients who underwent endolaryngeal surgery with curved video SL at our hospital during a 5-year period, the method provided complete accessibility and improved exposure of the glottis and anterior commissure. Representative endolaryngeal images are shown in Figure 2(a–c). Visualization and accessibility of laryngeal structures (vocal cords, vestibular folds, anterior commissure, and ventral subglottis) were easily obtained in all cases using the curved video SL system. Additionally, some patients with shorter necks, cervical spinal rigidity, obesity, and significant overbites were treated successfully with the curved laryngoscope.

Anatomically the larynx can be divided in three major chambers. This division is derived from the two pairs of mucosal folds, the vestibular or false vocal folds and the (true) vocal folds. The upper chamber lies between the laryngeal inlet, formed by the two aryepiglottic folds, the epiglottis, the arytenoids and the interarytenoid notch and the vestibular folds as the lower border. The middle chamber is between the vestibular folds and the vocal folds and contains the laryngeal ventricles on both sides. The lower chamber is located between the vocal folds and the inferior border of the larynx [18].

In April 2013, a 73-year-old male patient noticed a suspicious lesion on the left maxillary tuber, extending to the hard palate and the oral vestibular fold. A CT scan of the head and neck region confirmed the lesion as a mass on the maxillary tuber >2cm with active bone erosion of the left alveolar ridge. Multiple biopsies of the lesion revealed a hyperplastic epithelium with inflammatory cell infiltration and some atypical cells. This was identified as pseudo-epitheliomatous hyperplasia with chronic inflammation (Figure 2). Either way, oral VC could not be excluded and two weeks after diagnosis, treatment was initiated. As the patient refused any type of surgery, methotrexate (60 mg/m2, Qw) was administered after shared-decision making with patient and specialists. After eight weeks, a global regression of the tumor was observed and the patient had an acceptable toxicity profile. He continued this treatment and eventually received 28 cycles of methotrexate. At that time, the patient achieved macroscopic remission but unfortunately, 10 months after the last administration of methotrexate, the lesion recurred on the left maxillary tuber. Several biopsies could not confirm malignancy, nevertheless a hemi-maxillectomy was executed. Post-surgical histological examination showed presence of a low-grade oral SCC (squamous cell carcinoma) of the oral cavity (pT4a cN0 cM0), including positive resection margins. Additional surgery and adjuvant radiotherapeutic treatment (a total dose of 69,12 Gy in 32 fractions over 6, 5 weeks of the tumor region and a total dose of 56 Gy in the region of the elective cervical lymph nodes) was performed. No significant complications were withheld. Seven years post-therapy, the patient remains in remission without the need for active therapy.
