RESUMO

OBJECTIVE: To determine if oropharyngoplasty using a Gehanno technique of superior constrictor velopharyngoplasty, base of tongue mounding, and primary hypopharyngeal closure in combination with template-based revascularized free tissue transfer is effective for reconstruction of the oropharyngeal defect. DESIGN: Prospective case series. SETTING: Tertiary care academic medical center. PATIENTS: The study population comprised 25 patients (21 men and 4 women; mean age, 55.3 years) presenting from January 1998 to January 2001 with oropharyngeal squamous cell carcinoma. A comparison was performed based on the percentage of resection of the soft palate (group 1, < or =50% palate; group 2, >50% palate). INTERVENTIONS: Of the 25 patients, 24 (96%) received radiotherapy. The donor sites were radial forearm for 23 of 25 patients (92%) and lateral arm for 2 of 25 patients (8%). The mean area was 92 cm(2) (range, 25-150 cm(2)), and the mean length of the velopharyngoplasty component of the oropharyngoplasty was 2.15 cm (range, 1-3 cm). MAIN OUTCOME MEASURES: Gastrostomy tube dependence, major and minor complications, time to oral intake, speech and swallowing assessment, and quality-of-life assessment. RESULTS: Of the 25 patients, 2 (8%) remain gastrostomy dependent; 6 (24%) developed major complications; and 7 (28%) developed minor complications. Speech in both groups 1 and 2 was considered understandable most of the time, with occasional repetition. The group 1 patient with a median assessment score could eat a solid diet without restriction of place or person, whereas the group 2 patient with a median assessment score could eat a soft, moist diet with selected persons in selected places. CONCLUSION: Integration of oropharyngoplasty with template-based revascularized free tissue transfer produced speech results that were independent of palate defect size, and swallow function test results were similar to other published reconstructive techniques.

RESUMO

BACKGROUND: Retinoic acid (RA) has been shown to enhance ciliary ultrastructure in regenerated sinus mucosa compared with controls. However, the functional status of the regenerated cilia has not been studied. Our objective was to evaluate the ciliary beat frequency (CBF) of regenerated sinus mucosa treated with topical RA in a rabbit model. METHODS: Twelve rabbits underwent bilateral surgical stripping of the maxillary sinuses, followed by treatment with RA gel in the right side and an inert gel control in the left side. The rabbits were then killed at either 2 or 4 weeks, and CBF analysis of the regenerated mucosa was performed. Three unoperated rabbits were used to establish normative CBF data. RESULTS: Functional cilia were recovered from 11/12 RA-treated sinuses and 12/12 gel control sinuses. At 2 weeks postoperatively, the RA-treated sinuses showed an average CBF of 19.78 Hz, which was statistically comparable with the normal unoperated controls (p < 0.26). The inert gel-treated mucosa showed a CBF of 29.24 Hz, which was significantly elevated compared with normals (p < 0.05). At 4 weeks, ciliary activity persisted, but both RA-treated sinuses and gel controls showed elevated CBF compared with normals (p < 0.03). CONCLUSION: Topical RA placed in a demucosalized maxillary sinus yields functional cilia. RA appears to have a normalizing effect on CBF early in the mucosal wound healing process compared with control. This effect appears to be mitigated in later stages of wound healing. RA may be beneficial in enhancing morphological and functional aspects of regenerating cilia.

RESUMO

PURPOSE OF REVIEW: To provide an update on diagnostic methods and treatment options for Wegener's granulomatosis and to review common head and neck manifestations of the disease. RECENT FINDINGS: Recent advances have been made in the systemic treatment of Wegener's granulomatosis, including the introduction of investigational immunosuppressive agents such as etanercept, leflunomide and deoxyspergualin. Surgical options remain indicated in selected complications of Wegener's granulomatosis such as saddle nose deformity and subglottic stenosis. SUMMARY: Wegener's granulomatosis is an idiopathic, systemic vasculitis characterized by the formation of necrotizing granulomas of the respiratory tract in addition to focal or proliferative glomerulonephritis. Diagnosis is made by a combination of physical examination, laboratory studies and tissue biopsy. Head and neck manifestations are abundant and varied; common sites of involvement include the middle ear, nose and sinuses and subglottis. The mainstay of treatment remains systemic therapy using a combination of glucocorticoids and immunosuppressants. The otolaryngologist plays a key role in the diagnosis and treatment of head and neck complications of the disease. A surgical role exists for the management of nasal and sinus disease as well as laryngeal and tracheal disease.

RESUMO

OBJECTIVE: The purpose of this study was to determine the incidence of acute lung injury (ALI) in trauma patients with severe traumatic brain injury (TBI), to evaluate the impact of ALI on mortality and neurologic outcome after severe traumatic brain injury (TBI), and to identify whether the development of ALI correlates with the severity of TBI. METHODS: Clinical data were collected prospectively over a 4-year period in a Level I trauma center. Patients included in the study met the following criteria: mechanical ventilation > 24 hours, head Abbreviated Injury Scale score >or= 3, no other body region Abbreviated Injury Scale score >or= 3, and age between 18 and 54 years. ALI was defined using international consensus criteria. Glasgow Outcome Scale scores were assessed at 3 and 12 months. Bivariate comparisons were made between ALI and non-ALI groups. Multivariate analysis with stepwise logistical regression was used to assess independent factors on mortality. The patient's admission head computed tomographic (CT) scan was graded using the Marshall system, and the presence and size of specific intracranial abnormality was noted. Glasgow Coma Scale (GCS) score, Marshall CT scan score, and intracranial abnormality were correlated with the development of ALI. RESULTS: One hundred thirty-seven patients with isolated head trauma were enrolled in the study over a 4-year period. Thirty-one percent of patients with severe TBI developed ALI. Head trauma patients with ALI had a significantly higher ISS, a greater number of days on the ventilator, and a worse neurologic outcome for those who survived their hospitalization. Mortality was 38% in the ALI group and 15% in the non-ALI group (p = 0.004). Only 3 of 16 (19%) of the deaths within the ALI group were directly related to ALI. By multivariate analysis, only the presence of ALI, older age, and lower initial GCS score were associated with higher mortality. There was no association between ISS, the presence of arterial hypotension (arterial systolic pressure < 90 mm Hg) at admission to the hospital, or the amount of blood transfused and mortality. No correlation was found between the severity of head injury (GCS score, Marshall score, or intracranial abnormality) and development of ALI. CONCLUSION: The development of ALI is a critical independent factor affecting mortality in patients suffering traumatic brain injury and is associated with a worse long-term neurologic outcome in survivors. The risk of developing ALI is not associated with specific anatomic lesions diagnosed by cranial CT scanning.
