[The importance of laryngeal compartmentation in the limitation of tumor extension].

Histologic specimens from 75 patients with squamous cell carcinoma of the larynx treated exclusively by surgery were studied with special attention paid to the growth of the tumor in relation with the different laryngeal compartments. Some aspects traditionally admitted are discussed. The result show a not very close relation between the classic anatomic descriptions and the tumoral growing.

[Surgical treatment of post-thyroidectomy laryngeal paralysis].

A not infrequent complication of thyroid surgery is laryngeal nerve palsy with transitory or permanent deficiency of cordal motility. A very frequent cause of this condition is total thyroidectomy. Peripheral mono-or bilateral palsy in these cases may either occur, in adduction or abduction, and be complete or not complete. Therefore, different strategies in order to restore respiratory and phonatory functions are required. The Authors describe the main otorhinolaryngologic procedures used for the surgical treatment of laryngeal palsy, particularly for bilateral adducted ones. Their 10-year experience is also reported.

Late post radiation laryngeal chondronecrosis with pharyngooesophageal fibrosis.

Chondroradionecrosis of larynx is a well recognized complication of radiation therapy, which usually occur with in the 1st year. Review of literature shows very few accounts of late radiation induced clinical chondroradionecrosis of the larynx. This condition can mimic a local recurrence and severe and life threatening involvement will require aggressive surgical management as reported in the present case.

Pre-therapeutic evaluation of laryngeal carcinomas using computed tomography and magnetic resonance imaging.

A prospective and comparative computed tomography (CT)/magnetic resonance imaging (MRI) study on 90 patients with endoscopically examined and histologically proven laryngeal malignancy is presented. Post-operative pathological and intra-radiological (CT vs. MRI) correlations are established. We conclude that MRI is the method of choice for staging laryngeal malignancies.

[The application of multi-slice computed tomograph in diagnosis and operation of hypopharyngeal carcinoma].

OBJECTIVE: To evaluate the clinical application of multi slice CT(MSCT) in hypopharyngeal carcinoma and serve otolaryngologist to institute proper operation. METHOD: Forty-five patients with hypopharyngeal carcinoma scanned by MSCT were studied and confirmed by operation and pathologic examination. The operation material were retrospectively analyzed. All the cases were used for the enhancement scanning, whose scope was from hard palate to cervical segments of esophagus. RESULT: Of 45 cases, 34 cases derived from piriform fossa, 7 cases were from the postcricoid region and 4 cases were in the posterior wall of hypopharynx. The tumor showed isodense or mixed density and slightly enhancement, piriform fossa became narrow or disappeared, retropharyngeal soft tissue thickened, laryngeal cartilage and esophageal ostium were invaded and lymph nodes of neck became metastasis. The tumor pushed the annular and arytenoids cartilage displacement anteriorly; the thyroid arytenoidal gap and cricothyroid joint were widened. The operation plan that was made according as MSCT was almost agreed with actual operation. The consistent rate is 91.1% (41/45). CONCLUSION: MSCT examination can accurately diagnose and exhibit the extension of the tumors and detect metastasis to lymph nodes, and provide reliable basis for surgery therapy.

Laryngomalacia: a classification system and surgical treatment strategy.

Laryngomalacia, the most common congenital laryngeal anomaly, is not a single disease entity but rather a variety of entities along a spectrum of underlying pathophysiologies. Based on our study of 10 children who were surgically treated for laryngomalacia in an urban tertiary care center, we have developed a system of classifying laryngomalacia on the basis of its different underlying pathophysiologic processes. Type I laryngomalacia is characterized by a foreshortened or tight aryepiglottic fold. Type 2 disease is defined by the presence of redundant soft tissue in the supraglottis. The type 3 designation applies to cases caused by other etiologies, such as underlying neuromuscular disorders. While the three types are not mutually exclusive, each should be considered as a separate disease entity with a final common clinical presentation. Each type requires a specific approach to surgical repair.

[Magnetic resonance imaging of the larynx. Its contribution compared to x-ray computed tomography in the pre-therapeutic evaluation of cancers of the larynx. Apropos of 90 surgical cases].

The authors report a prospective and comparative study of the pre-operative staging of 90 laryngeal carcinomas by CT and MRI, with blind analysis of each examination. The radio-anatomic correlations and the inter-method correlations (CT versus MRI) are reported. According to the authors MRI seems to be the method of choice because of its capabilities in soft tissues differentiation and because of its multiplanar representation. The motion artefacts are resolved by the fast imaging technique and the spatial resolution is optimized by special surface coils.

Functional anatomy of the larynx.

The larynx serves three basic functions in humans. In order of functional priority they are protective, respiratory, and phonatory. This article discusses these three roles in terms of phylogeny, developmental anatomy, and neuromuscular reflex activity.
