hemilaryngectomy

(hĕm′ĭ-lăr′ən-jĕk′tə-mē)
n.
Surgical excision of one side of the larynx.

hemilaryngectomy

The partial excision of the larynx for invasive cancer (usually, squamous cell carcinoma), which removes the anterior soft parts of the larynx in continuity with the underlying thyroid cartilage. Hemilaryngectomy is a voice-conserving procedure that consists of dividing the thyroid cartilage at the midline and resecting—in continuity—the thyroid cartilage with the corresponding true and false vocal cords and ventricles.

Indications
Up to T2 glottic tumours.

Contraindications
Subglottic extension > 10 mm anteriorly or > 5 mm posteriorly; most T3 glottic cancers; involvement of an entire vocal cord and more than one-third of the contralateral vocal cord.

No patients were treated with hemilaryngectomy. Patients also received concurrent chemoradiation with weekly cisplatin (40 mg/[m.sup.2]) from the first day of radiation therapy (RT) for up to 7 cycles.
(2) presented two patients who had superficial keratotic vocal cord lesions and underwent hemilaryngectomy with the diagnosis of verrucous carcinoma, and in whom local excision was performed due to the diagnosis of squamous papilloma.
Although, hemilaryngectomy or cordectomy produces comparable cure rates for selected T1 and T2 vocal cord lesions, RT is generally preferred.
For example, some such cases may be improved through resection of the scarred hemilarynx and creation of a pseudovocal fold using modifications of strap muscle techniques employed routinely for cordectomy or vertical hemilaryngectomy. (8) Certainly, this is an unusual and extreme approach for the treatment of vocal fold scar, but it is an option that should be in the surgeon's armamentarium for the rare, appropriate patient.
For the two participants with hemilaryngectomy and one nonsurgical participant, this maneuver resulted in BOT to PPW pressures near those demonstrated with participants who are nondisordered [17].
The remainder underwent total laryngectomy with unilateral or bilateral dissection (16%) chordectomy (4%), supraglottic laryngectomy (3%), hemilaryngectomy (2%) and hemilaryngectomy with dissection (1%).
(10) In 2001, 2 reports of mesenchymal tumors treated with conservative surgery were published; Ianniello et al (6) reported using vertical hemilaryngectomy, and Veivers et al (10) used supracricoid partial laryngectomy with cricohyoidoepiglottopexy.
