Liposarcoma of the larynx.

OBJECTIVES: The objective was to review the presentation, diagnosis, treatment, and prognosis of patients with laryngeal liposarcoma (LLS). A case is reported, and a retrospective review of the English-language literature is presented. METHODS: All published cases of LLS with adequate histopathologic documentation and clinical information were included for review. RESULTS: Thirty cases of LLS have been reported. A majority of these patients are men between 40 and 70 years of age. The most common location of the tumor is the supraglottis, and the presenting complaints are similar to those of other laryngeal neoplasms. Although these neoplasms recur often and can cause significant morbidity, they are typically of low grade and rarely metastasize. The outcomes of this disease are generally good when it is treated with wide surgical excision. CONCLUSIONS: Cases of LLS are extremely rare. Because the histologic changes are frequently subtle, LLS can be easily mistaken for a benign tumor. As a result, the diagnosis requires a high index of suspicion and diligence in examining biopsy specimens. Computed tomography and magnetic resonance imaging can assist in the diagnosis and surgical approach. Genetic and immunostaining analysis techniques may also prove to have valuable prognostic, diagnostic, and therapeutic implications for this disease. Wide surgical excision is the mainstay of treatment. The use of radiotherapy and chemotherapy in treating this cancer remains experimental, but might be considered on a case-to-case basis for palliation or to treat aggressive variants of the disease.

High-resolution computed tomography of temporal bone: Part IV: Coronal postoperative anatomy.

The purpose of this 4-part series is to illustrate the nuances of temporal bone anatomy using a high-resolution (200 micro isotropic) prototype volume computed tomography (CT) scanner. The normal anatomy in axial and coronal sections is depicted in the first and second parts. In this, the fourth part, and the third part, the structures that are removed and/or altered in 9 different surgical procedures are color coded and inscribed in the same coronal (article IV) and axial (article III) sections. The text stresses clinically important imaging features, including the normal postoperative appearance, and common complications after these operations. The superior resolution of the volume CT images is vital to the comprehensive and accurate representation of these operations. Minuscule intricate structures that are currently only localized in the mind's eye because of the resolution limit of conventional CT are clearly seen on these scans. This enhanced visualization, together with the information presented in the text, should assist in interpreting temporal bone scans, communicating with surgeons, and teaching this complex anatomy.

Symptoms, quality of life, videolaryngoscopy, and twenty-four-hour triple-probe pH monitoring in patients with typical and extraesophageal reflux.

A prospective study was designed to characterize patients with typical and extraesophageal reflux (EER) symptoms and seek predictive patterns for each group. Fifteen subjects without symptoms, 16 patients with symptomatic gastroesophageal reflux disease (GERD), and 37 patients with symptomatic EER were evaluated with outcomes tools, videolaryngoscopy, and 24-hour triple-probe pH monitoring. Higher symptom scores, Voice Handicap Index scores, and Gastrointestinal Symptom Rating Scale scores, as well as similarly decreased quality of life as measured by the Short Form 36, were noted among the two symptomatic groups. Patients with clinically diagnosed EER were more likely to have multiple abnormalities on laryngoscopy. There was a trend toward more pharyngeal reflux episodes in EER patients (6.9 +/- 8.9) as compared to GERD patients (6.0 +/- 9) and asymptomatic subjects (1.1 +/- 1.9). On the basis of the pH monitoring of asymptomatic subjects, we define pathological pharyngeal reflux as more than 5 episodes in 24 hours. Pharyngeal acid exposure is more common in patients presumed to have EER, but some pharyngeal reflux does occur in asymptomatic subjects. Neither symptom scores nor videolaryngoscopic findings were predictive of pathological EER as indicated by pH monitoring.

Clinical outcomes for the surgical treatment of sinonasal headache.

OBJECTIVE: This study was designed to explore the changes in patient-relevant clinical outcomes in a selected group undergoing surgery for nasal septal and turbinate abnormalities. Study design Seventy-nine consecutive patients with headache and correctable anatomic nasal obstruction were seen at the study institution from March 1998 to May 2000. These patients were evaluated for changes in patient-relevant clinical outcomes measures after surgical correction of their anatomic abnormalities. RESULTS: Seventy-one patients underwent surgical correction of nasal obstruction. More than half of these patients had contact points preoperatively. Statistically significant improvements were observed in the patient population with respect to 8 of the 10 clinical outcomes measures. Importantly, a decrease in the severity and frequency of headaches was noted after surgery, especially after the correction of contact points. CONCLUSION: The surgical correction of the septum and turbinates resulted in predictable improvement in headache and a majority of other important outcomes measures. Clinical significance Pain may improve after surgical correction of septal and turbinate abnormalities in a properly selected group.
