HYPOTHESIS: The goal of this study was to evaluate the effects of hyaluronic acid, epidermal growth factor, and mitomycin C on the healing of acute experimental traumatic perforations of the tympanic membrane. BACKGROUND: Most acute perforations of the tympanic membrane heal spontaneously. However, some form of surgical treatment (i.e., myringoplasty) is needed for nonhealing perforations. Because the closure occurs by squamous epithelial migration, drugs that stimulate this regenerative process may aid in the closure of the perforation, obviating the need for more extensive treatments. METHODS: Bilateral perforations of the tympanic membrane were created in 30 rats, divided into three groups (A, B, C). The perforations in the right ears were treated with hyaluronic acid, epidermal growth factor, or mitomycin C. Those in the left ears were left untreated for comparison. To examine the healing process in different periods, 5 animals were killed in each group at days 3, 5, 7, 9 and 14. The other 5 animals in each group were observed daily to determine the duration of perforation closures. Thirty surgical specimens (5 right sides from each group and all 15 left sides in all groups) were histopathologically examined for tympanic membrane thickness, fibroblastic reaction, neovascularization, and crust morphology. RESULTS: Hyaluronic acid and epidermal growth factor applications significantly shortened the healing in acute experimental traumatic perforations of the tympanic membrane (p = 0.0432); however, the difference between them was not significant (p = 0.3160). On the other side, tympanic membrane perforations treated with topical mitomycin C showed no evidence of closure. There were no significant differences in the histologic parameters between the treated groups and their contralateral control ears. CONCLUSION: Hyaluronic acid and epidermal growth factor accelerated the closure of acute tympanic membrane perforations in rats. This may make them clinically useful in augmenting the efficiency of conservative treatments of acute perforations of the tympanic membrane.
OBJECTIVES: We investigated the incidence of level I metastasis in patients with laryngeal and hypopharyngeal squamous cell carcinoma (SCC). PATIENTS AND METHODS: The records of 126 patients who underwent primary tumor excision with radical neck dissection (RND) or its modifications for laryngeal or hypopharyngeal SCC were retrospectively reviewed. Preoperative tumor and neck stages, the sites and the number of metastatic lymph nodes were recorded. Patients treated with selective neck dissection (SND) or preoperative chemotherapy and/or radiation therapy were excluded. RESULTS: Of 155 RND or modified RND performed for 113 laryngeal and 13 hypopharyngeal SCC, lymph node metastases were detected in 51 specimens, all of which spared level I. The most frequently involved levels were II and III. CONCLUSION: Selective neck dissection sparing level I may be appropriate for clinically and radiologically N0 patients with laryngopharyngeal carcinoma.
Medial maxillectomy is the standard operation for en bloc resection of the lateral nasal wall with portions of the maxillary and ethmoid sinuses. Although most reports comment on good to excellent cosmetic results, nasal collapse is a possible complication of the procedure and is best explained by the loss of lateral nasal wall support. To overcome this problem, we describe a technique with temporary mobilization of a bone frame around the ipsilateral pyriform aperture, including one nasal bone, and fixing it to its original position at the end of the operation.
A three-year-old girl with a lingual plexiform neurofibroma treated by total excision is presented. Despite their occurrence in the head and neck region, neural sheath tumors are rarely encountered in the oral cavity. It is reported that 4-7% of patients affected by neurofibromatosis display oral manifestations. Neurofibromatosis is characterized by café-au-lait spots and cutaneous neurofibromas. Plexiform neurofibroma is said to be indicative of von Recklinghausen's disease (VRD) even though it may be the only manifestation of the disease. Generally, surgical resection represents the treatment of choice and the diagnosis can only be confirmed after histological examination. Affected patients need regular follow-up to detect malignant degeneration, an early recurrence or appearance of other manifestations of VRD.
