Nuances in the management of rhinophyma.

Rhinophyma is a cosmetically disfiguring disease of the external nose that most frequently affects elderly Caucasian males. Frequently, there is associated derangement of nasal airway patency. Although the true incidence of rhinophyma and its exact etiology remain unknown, it is widely believed to represent the final stage in a continuum of acne rosacea. Medical therapy has not been effective in reversing the disease process, and surgery remains the most accepted method of treating rhinophyma. A wide variety of surgical techniques have been developed and modified over the years in an effort to treat this disorder safely and without significant sequelae. Despite many advances in fundamental understanding, surgical techniques, and related technologies, no single method has been universally embraced and employed as the "gold standard." This review describes the most commonly employed modern surgical techniques and methods used throughout the world to treat rhinophyma. There is special emphasis on the authors' preferred method of excision and postoperative management (tumescent anesthesia, Weck blade excision, and argon beam coagulation), which has been demonstrated to be effective and expeditious.

Dual action of TGF-beta1 on nasal-polyp derived fibroblasts.

OBJECTIVES: Transforming growth factor beta-1 (TGF-beta1) is a known fibrogenic factor with immunosuppressive properties. We wanted to determine the effect of stimulation with TGF-beta1 on nasal polyp-derived fibroblasts and assess the role this molecule would have in polyp formation and growth. STUDY DESIGN: Nasal-polyp derived fibroblasts were cultured with or without TGF-beta1, and proliferation and cytokine secretion were measured. METHODS: Fibroblasts were isolated from nasal polyps following endoscopic surgery. Cells were plated and grown until confluent, after which they were split and used in assays. Cells were stimulated with TGF- beta1 and mRNA collected after 16 hours, supernatants after 72 hours, and proliferation measured after 96 hours of culture. RESULTS: TGF-beta1 significantly (P < .02) increased proliferation of nasal-polyp derived fibroblasts. We examined the expression of inflammatory cytokines and found that TGF-beta1 decreased expression of CCL2 (MCP-1), CCL5 (RANTES), CCL11 (eotaxin), granulocyte-colony stimulating factor (G-CSF), and GM-CSF (P < .05). In contrast, incubation with TGF-beta1 increased fibronectin, procollagen, vascular endothelial growth factor (VEGF), and TGF-beta2 protein production (P < .05). For select samples, we confirmed that the increased protein production was due to increased mRNA expression. CONCLUSION: These studies suggest that TGF-beta1 expression in polyp tissue can have dual effects. One role is to act as an anti-inflammatory agent shown by the ability to inhibit pro-inflammatory mRNA and protein production. At the same time, TGF-beta1 expression leads to increases in factors involved in fibrosis and angiogenesis, promoting remodeling and cell growth.

Radiographic classification of temporal bone fractures: clinical predictability using a new system.

OBJECTIVE: To compare the traditional system of radiographic classification of temporal bone fractures (transverse vs longitudinal vs oblique) with a newer system (otic capsule violating vs otic capsule sparing) with respect to their ability to predict sequelae of temporal bone trauma. DESIGN: Retrospective chart and radiology review. SETTING: University trauma center and Department of Otolaryngology-Head and Neck Surgery. PATIENTS: Patients with temporal bone fractures. INTERVENTIONS: Clinic records and computed tomographic scans were reviewed to evaluate the clinical predictability of complications of temporal bone fractures. MAIN OUTCOME MEASURES: Complications of temporal bone fractures (ie, sensorineural hearing loss, conductive hearing loss, cerebrospinal fluid leakage, and facial nerve weakness) were recorded. Two classification schemes for temporal bone fractures were statistically analyzed and compared as to their ability to predict each complication. RESULTS: A total of 234 temporal bone fractures were identified; 30 cases met our strict criteria for inclusion. The traditional classification system of temporal bone fractures did not significantly predict temporal bone complications (P = .71). On the other hand, the otic capsule-based system did demonstrate statistically significant predictive ability (P < .001). Patients with otic capsule-violating fractures were 5 times more likely to have facial nerve injury, 25 times more likely to have sensorineural hearing loss, and 8 times more likely to have cerebrospinal fluid otorrhea than those with otic capsule-sparing fractures. CONCLUSIONS: The traditional radiographic classification system failed to demonstrate clinical predictability in our series. Furthermore, the newer system of classification (otic capsule sparing vs otic capsule violating) demonstrated statistically significant predictive ability for serious clinical outcomes associated with temporal bone fractures.

Complications with forehead flaps in nasal reconstruction.

OBJECTIVES/HYPOTHESIS: To determine what characteristics and comorbidities are associated with a higher rate of complications in patients undergoing nasal reconstruction with a forehead flap. STUDY DESIGN: Retrospective chart review. METHODS: Chart review was completed on all patients undergoing nasal reconstruction with forehead flap from 1995 to 2008. Three pre-existing comorbidities were tracked: diabetes, smoking, and vascular disease. Major complications (flap necrosis, nasal obstruction, alar notching) and minor adverse outcomes (partial nasal obstruction, epidermolysis, and alar asymmetry) were recorded. RESULTS: Two hundred five patients with a median age of 66 years had forehead flap reconstruction between October 1995 and July 2008. Sixty-two patients (30.2%) had full-thickness defects. Forty-eight patients (23.4%) were smokers, 17 (8.3%) were diabetics, and 90 (43.9%) fell into our category of vascular disease. Thirty-three (16.1%) developed a major complication at some point in their postoperative course, with 11 (5.4%) having some degree of flap necrosis, 10 (4.9%) nasal obstruction, and 20 (9.8%) alar notching. Full-thickness defects were significantly associated with higher incidences of any major complication, and had higher odds of flap necrosis and alar notching. Smokers had higher odds of developing flap necrosis. Neither the presence of diabetes, increased age, nor vascular disease was significantly associated with higher rates of major complications. CONCLUSIONS: Smokers with full-thickness defects are shown to be at greater odds for developing a postoperative complication. Laryngoscope, 2009.

Small cell carcinoma of the submandibular gland: a rare small round blue cell tumor.

The presence of small cell carcinoma within the submandibular gland is an uncommon clinical entity. However, other small round blue cell tumors are encountered in the head and neck with greater frequency. These include lymphoma, Ewing's sarcoma, melanoma, esthesioneuroblastoma, and neuroblastoma. A basic knowledge of the immunohistochemical studies available to distinguish each these tumors from one another significantly improves the frequency of accurate and timely initial diagnosis. We report a case of small cell carcinoma of the submandibular gland and review the other common small round blue cell tumors that occur within the head and neck. We utilize an acronym, LEMONS, to organize our review and facilitate improved retention of the differential diagnosis for small round blue cell tumors of the head and neck.
