“…Despite this individual case may lead to use CT in the follow-up of every patient, we agree with other authors who say that after surgery of the larynx, CT is effective only to assess the submucosal extent of recurrences [2,40,41]. This requires the knowledge of normal postoperative CT findings to prevent misinterpretation of changes in laryngeal structures.…”

The purpose of this study was to evaluate the normal CT appearance of the larynx after conservative and radical surgery. Postoperative (conservative surgery n = 52, radical surgery n = 21) CT examinations of 73 patients suspected of local/regional recurrence (n = 53) or asymptomatic (n = 20) were retrospectively analysed. The CT findings of 45 patients negative at biopsy were utilised to assess the normal appearance after surgery. Changes in the laryngeal framework represented constant landmarks, whereas the variety of soft tissues resection often resulted in a more unpredictable appearance of the neolarynx. Considerable thickening of the mucosa covering the arytenoid cartilage(s) has been detected after horizontal supraglottic laryngectomy (40 %) or supracricoid laryngectomies (SL; 100 %). A "pseudocord" due to scar tissue appeared to be a constant finding following vertical haemilaryngectomy, frequently after SL. Dilation of a lateral recess of the hypopharynx was observed after SL. This "pharyngeal pouch" had considerable size and air or liquid content. The most frequent CT findings among 28 tumours recurrent after conservative or total surgery were a mass larger than 10 mm spreading beyond the larynx (63.1 %), thickening of anterior commissure (57.9 %), erosion of residual cartilages (16.9 %). Although CT detected one subclinical recurrence, its employment is justified only to assess the submucosal extent of the lesion. This requires a thorough knowledge of normal postoperative findings.

“…According to the literature, CT presents a higher staging accuracy (between 68% and 82.7%) than the clinical examination (between 52% and 74.3%) for supraglottic tumors. This staging accuracy potentialized with the association between CT and clinical evaluations, reaching 91.4% of effectiveness (4,7,(11)(12)(13)(14)(15)(16)(17) .…”

“…Also, according to data in the literature, CT determines an increase in clinical staging ranging between 19.4% and 30.7% (3,12,15,18) . In the present study, this upstaging was observed in 38.5% of cases, similarly to the findings of other authors; main reasons were: cartilages invasion, infiltration into the pre-epiglottic and paraglottic spaces, and extralaryngeal tumor extension that had not been detected by laryngoscopy (Table 2).…”

Contribuição da tomografia computadorizada no estadiamento do carcinoma de células escamosas da supraglote

OBJETIVO: Este trabalho tem como objetivos avaliar a influência da tomografia computadorizada no estadiamento local da classificação TNM dos tumores da supraglote e avaliar a concordância interobservadores na detecção da extensão tumoral. MATERIAIS E MÉTODOS: Foram avaliados, retrospectivamente, 39 pacientes com carcinoma de células escamosas da supraglote atendidos no Hospital Heliópolis entre 1988 e 1998. Os exames de tomografia computadorizada foram analisados por dois radiologistas individualmente. Para a avaliação da concordância interobservadores utilizou-se o índice kappa. RESULTADOS: A tomografia computadorizada foi determinante no estadiamento mais avançado em 38,5% dos casos, decorrente de extensão tumoral profunda não-identificada no exame clínico. CONCLUSÃO: A concordância interobservadores foi considerada ótima para as pregas vocais e subglote; boa para a supraglote, espaços paraglótico e pré-epiglótico, cartilagens cricóide e tireóide e para extensão tumoral extralaríngea; e regular para a base da língua.

“…Bardley A et al (1990) in their study reported that supraglottic tumors may also cephalad within the pre-epiglottic space to invade the tongue base without distorting the mucosa of the vallecullae. 55 Dullerud R et al (1992) found that CT did not change the classification for T 1 and T 2 glottic tumors. They concluded that CT is manadatory only in advanced tumors of glottic region or when the anterior commissure is involved.…”

Carcinomas of larynx and hypopharynx are the very common primary head and neck malignancies.Incidence is strongly related to age, and is rare before 40 years of age. The larynx and hypopharynx are closely integrated anatomically and functionally. Anatomically larynx is divided into the three sub divisions and certain potential spaces through which cancer tends to spread outside the site of its origin. The causal relationship between alcohol and tobacco intake, genetic predisposition, diet, and socioeconomic conditions in the development of squamous cell cancers of the head and neck applies as well to laryngeal and hypopharyngeal cancer. Site predilection for the origin of cancers of laryngeal cancers being Glottic carcinoma being 60 to 65%, Supraglottic carcinoma 30 to 35% and Subglottic carcinoma less than 5%. Site predilection for the origin of cancers of hypopharyngeal cancers being pyriform Sinus 70%, post cricoid region 15% and posterior pharyngeal wall 15%. Clinico-endoscopic evaluation can be undertaken with indirect laryngoscopy, fibreoptic laryngoscopy / telescopic laryngoscopy (70 0 hopkins) and direct laryngoscopy. Imaging (USG, CECT±CEMRI) plays a significant complementary role to clinical endoscopy in pretherapeutic staging of laryngeal and hypo pharyngeal malignancies. Determination of the precise extent of cancer spread within the larynx (T staging) is the single most critical factor guiding treatment decisions in patients with localised laryngeal cancer. In present study out of 25 patients of laryngeal and hypopharyngeal malignancies, 16 (64%) patients were treated by radiotherapy or concurrent chemoradiation, 4 (16%) patients were treated by total laryngectomy with neck dissection and 3 (12%) patient were treated by total laryngectomy with partial pharyngectomy with neck dissection and 2 (8%) patients were treated by total laryngectomy alone.
