Treatment of Maxillary Sinus Carcinoma: Clinical Results Using the Kitasato Modality

The conventional therapeutic regimen for maxillary sinus carcinoma consists of dissection of the maxilla, full-dose irradiation and extensive chemotherapy. However, the results obtained with this treatment are often poor. Even when patients recover, their quality of life is significantly reduced as a result of deformity of facial structures and swallowing and articulation dysfunctions. A retrospective analysis of 68 patients with maxillary sinus carcinoma treated with the Kitasato modality between 1975 and 1999 was conducted. All patients underwent pergingival maxillary sinus surgery combined with pre- and postoperative irradiation therapy with standardized total doses of 16 Gy; the postoperative irradiation was given in combination with regional intra-arterial infusion chemotherapy administered via the superficial temporal artery. All visible tumor lesions were removed where possible in order to preserve or facilitate cellular immunity after surgery. The cumulative 5-year survival rates were 85.7% for Stage II patients, 88.1% for Stage III, 76.6% for Stage IVA and 75.0% for Stage IVB.     

Tongue Base Reduction with Temperature-controlled Radiofrequency Volumetric Tissue Reduction for Treatment of Obstructive Sleep Apnea Syndrome

In recent years a considerable effort has been made to establish the use of different surgical techniques for the treatment of obstructive sleep apnea syndrome (OSAS). Nevertheless, treatment of hypopharyngeal obstruction due to tongue base hypertrophy remains in many ways an unsolved problem. The aim of this study was to evaluate the safety and efficacy of tongue base reduction with temperature-controlled radiofrequency volumetric tissue reduction in the treatment of OSAS. Twenty patients with OSAS and tongue base hypertrophy were treated with radiofrequency tissue ablation. An intensified treatment protocol was used, delivering 2,800 J per treatment session under local anesthesia. Two nights of polysomnography testing were performed before and after treatment. Daytime sleepiness, snoring and postoperative morbidity were assessed using questionnaires. Mean respiratory disturbance index (RDI) was reduced from 32.1 to 24.9/h after a mean of 3.4 treatment sessions. Six patients (33%) were cured after the procedure (reduction in RDI of &#83 50% and a postoperative RDI of <15/h) and ten (55%) showed an improvement of >20% in their RDI. Daytime sleepiness and snoring improved significantly. Peri- and postoperative morbidity was low; one severe complication occurred (tongue base abscess). We were able to achieve similar cure and responder rates to those reported in a recently published pilot study but with a reduced number of treatment sessions. We believe that this technique may improve patient acceptance and have beneficial cost implications.     

Congenital nasal masses: diagnosis and management

Reverse Optokinetic After-nystagmus Generated by Gaze Fixation During Optokinetic Stimulation

Gaze fixation during optokinetic stimulation generates an after-nystagmus with a slow component towards the reverse direction of the optokinetic stimulation. The duration and maximum slow component velocity (SCV) of this "reverse OKAN" were observed by changing the duration, velocity and direction of the optokinetic stimulation in nine normal volunteers. The duration of reverse OKAN increased with increasing stimulation time but was unaffected by changes in the stimulation velocity. The maximum SCV of reverse OKAN decreased with an increase in the stimulation velocity but was not significantly affected by changes in the optokinetic stimulation time. There was no directional difference among the horizontal, upwards and downwards reverse OKANs. The reverse OKAN was thought to be generated by a mechanism different from the velocity storage mechanism which produced optokinetic nystagmus and the first phase of OKAN. Retinal slip during the optokinetic stimulation was considered to be an input to the mechanism which generated the reverse OKAN. We hypothesize that the mechanism causing the reverse OKAN may be a generator of the second phase of OKAN, which was also intimately connected with self-motion sensation during the optokinetic stimulation.     

Tissue-engineered human nasal septal cartilage using the alginate-recovered-chondrocyte method

OBJECTIVES: Tissue engineering of nasal septal cartilage has numerous potential applications in craniofacial reconstruction. Chondrocytes suspended in alginate gel have been shown to produce a substantial cell-associated matrix. The objective of this study was to determine whether cartilage tissue could be generated using the alginate-recovered-chondrocyte (ARC) method, in which chondrocytes are cultured in alginate as an intermediate step in tissue fabrication. METHODS: Nasal septal chondrocytes from five patient donors were isolated by enzymatic digestion, then expanded in monolayer culture. At confluency, a portion of those cells were seeded at high density onto a semipermeable membrane and cultured for 14, 21, or 28 days (monolayer group). The remaining cells were suspended in alginate and cultured until a cell-associated matrix was observed (10-17 days). Cells and their associated matrix were released from alginate (ARC group), seeded onto a semipermeable membrane, and cultured as already described. DNA (Hoechst 33258 Assay), glycosaminoglycan (GAG; dimethylmethylene blue assay), and collagen (hydroxyproline assay) were analyzed biochemically. Immunohistochemistry was performed to assess expression of collagens type I and type II. Histochemistry was performed to localize cells accumulating sulfated GAG (Alcian blue stain). RESULTS: The ARC constructs, in contrast to the monolayer constructs, had substantial structural stability and the histologic and gross appearance of cartilaginous tissue. ARC constructs demonstrated significantly greater GAG and collagen accumulation than monolayer constructs (P <.05). Histologic analysis revealed substantial GAG and collagen type II production and only moderate collagen type I production. The composition of the matrix was thus similar to that of native human septal cartilage. CONCLUSIONS: Tissue-engineered human nasal septal cartilage using the ARC method has the histologic and gross appearance of native cartilage and has biochemical composition more like that of native cartilage than monolayer constructs. This is the first report of human nasal septal neocartilage formation without the use of biodegradable scaffolds.     

Jaw osteosarcomas

Introduction

Osteosarcoma (OS) is the most frequent bone malignant tumor. It is usually found on long bones, 5 to 10% are located on jaws, accounting for 0.5 to 1% of all facial tumors. There is little published data which concerns only few patients. Our aim was to study retrospectively cases of facial bone OS in adults, and to compare our results with published data to suggest an optimal management scheme.

Patients and method

Thirty-three patients were managed for an OS, from January 1997 to January 2007. Fourteen patients with a maxillary and mandibular OS, treated in first-intention in our unit, were included. The following data were analyzed: age; personal history; circumstance of discovery; clinical, functional, and physical signs; loco-regional extension and metastasis radiological investigation. The histological slides were systematically reviewed. The protocol, therapeutic outcome, and follow-up were studied.

Results

The mean age at diagnosis was 43. Swelling was the most frequent functional sign. The mean delay before management was 3.4 months. The most frequent radiological presentation was a lytic and hyperdense image. The diagnosis was suggested after CT scan in 57.1% of cases. The biopsy was correlated to the anatomopathological analysis in 78.6% of cases. The most common treatment was surgical exeresis completed by chemotherapy. The 5-year survival rate was 50%.

Discussion

Jaw OS are specific because of their localization and specific bone ultrastructure. Their management remains controversial: should they be managed like limb OS or treated more specifically? Neoadjuvant chemotherapy, even if it delays exeresis for 3 months, seems to stop the growth or reduce the tumor. An early anatomopathological analysis of the surgical piece determines adjuvant therapy. The negative prognostic factors are: maxillary localization because of limited exeresis margins, tumoral size, and osteoblastic sub-type.     

Patterns of practice regarding surgical site infection prevention in head & neck surgery: An international survey

IntroductionHead & neck surgery encompasses a variety of surgical approaches for benign and malignant conditions. Due to the complexity in treating patients with head and neck pathology, it is necessary to adhere to basic surgical principles to decrease complications. Among them, surgical site infection can be prevented using a surgery quality protocol including the correct use of antibiotics and optimization of nutritional status.Materials and methodsA survey was sent through the YO-IFOS and SEORL-CCC international mailing list.ResultsA total of 435 surgeons completed the survey. Of the respondents, 97.7% confirm that they scrub their hands before surgery, 40.9% respondents recommend nutritional support according to sign and symptoms, 60.9% use of antibiotic prophylaxis in clean surgery and just 9.2% use clindamycin in combination.ConclusionThis survey has broadened the scope regarding H&N surgical safety around the globe. Identifying innovative ways in which surgical care may be improved is mandatory.
