Palatal reconstruction with the palatal island flap.

OBJECTIVES/HYPOTHESIS: The management of palatal defects resulting from the extirpation of benign and malignant lesions uses a variety of methods, with the optimal techniques allowing maximal postoperative function with minimal morbidity. The palatal island flap is an effective, reliable technique for reconstructing postablative oral cavity defects. METHODS: All patients who underwent palatal resections for benign or malignant lesions at a tertiary care, referral-based head and neck cancer center since 1995 were eligible. Ten patients were identified whose surgical defects were reconstructed with palatal island flaps. The cases were reviewed for the symptomatology, tumor features, defect size, perioperative and postoperative management, complications, and impact on palatal function. RESULTS: Ten patients ranging in age from 18 to 81 years underwent palatal island mucoperiosteal flaps after resection of a variety of benign and malignant tumors, most arising from minor salivary glands. The defects ranged in size from 5 to 15 cm2, with extension into the floor of the nose in four cases and to the skull base in two. Nine patients were discharged on a regimen of oral diet, and no patient manifested permanent velopharyngeal insufficiency, speech impairment, or airway compromise. Follow-up ranged from 3 months to 6 years, with an average follow-up of 18.5 months. Delayed donor site re-epithelialization required debridement in one case, and two patients required obturation of small oronasal fistulae. CONCLUSION: The palatal island mucoperiosteal flap provides an effective means of reconstructing hard and soft palate defects with few complications and low morbidity.

Incidental metastatic papillary thyroid carcinoma in microvascular reconstruction.

OBJECTIVES/HYPOTHESIS: Occult papillary thyroid carcinoma has a reported prevalence of 1% to 35% based on autopsy studies. Cervical lymphatic metastases from papillary thyroid carcinoma have been associated with a higher likelihood of recurrence with a questionable impact on survival. Without clinically evident disease in the thyroid or cervical nodes, management of these patients presents a treatment dilemma. We propose an individualized treatment plan for patients in whom metastatic papillary thyroid carcinoma is incidentally detected during neck exploration for other purposes. STUDY DESIGN: Retrospective review and discussion of the literature. METHODS: The clinical course of two patients with incidentally discovered metastatic papillary thyroid carcinoma to the cervical lymph nodes is described. Both patients had previously received head and neck irradiation in childhood and required free flap reconstruction of extensive skull base defects following extirpation of meningiomas. RESULTS: Neck dissection specimens from levels I and II obtained during exposure of recipient vessels for microvascular tissue transfer revealed papillary thyroid carcinoma in both cases. The patients subsequently underwent total thyroidectomy, neck dissection, and postoperative radioactive iodine ablation of residual thyroid tissue. After 1 year of follow-up, both patients were without evidence of recurrent disease. CONCLUSIONS: An individualized approach is justified to treat metastatic papillary thyroid carcinoma incidentally discovered during other procedures. The case reports underscore the importance of pathological analysis of surgical specimens obtained during head and neck reconstruction.

Bilateral Lemierre's syndrome: a case report and literature review.

Lemierre's syndrome is characterized by thrombosis of the internal jugular vein that develops following an oropharyngeal infection. Sepsis and septic metastases frequently ensue and affect the lungs, the musculoskeletal system, and occasionally the liver. Most cases are caused by infection with Fusobacterium necrophorum. This infection responds to antibiotic therapy with beta-lactamase-resistant compounds that exert good anaerobic coverage. Anticoagulation and surgical intervention can be helpful in advanced cases. Fewer than 160 cases of classic Lemierre's syndrome have been described; approximately one-third of these reported cases have occurred since 1988. We describe a new case of Lemierre's syndrome that occurred in an otherwise healthy 27-year-old man. Thrombosis of both internal jugular veins extended through the subclavian system and into both upper extremities. The patient was treated with intravenous antibiotics and heparin during 14 days of hospitalization. He was discharged on oral clindamycin and warfarin sodium, and after 6 months he was able to return to full activity. To our knowledge, this is the first reported case of Lemierre's syndrome in which internal jugular vein thrombosis occurred bilaterally. By reporting this previously undescribed manifestation of Lemierre's syndrome, we hope to increase practitioner awareness of this disease entity.
