The cleft alveolus is one of three parts in cleft deformity. The purpose of cleft alveolus bone grafting is the recovery of normal esthetics, occlusion and speech. If a bony defect is extended to the nasal floor, especially wide bony defect at the ala base, it is difficult to condense the cancellous bone during bone transplantation and to reconstruct the normal anatomy at the alar base. We treated with above mentioned cleft alveolus patients using the autogenous cortical bone effectively. We report this technique with two cases and the literatures review.

The treatment of cleft lip and palate must be based on a complete knowledge of the anatomy, physiology and growth of the involved deformity, because of not only the appearance but also impaired functions such as phonation, mastication, respiration and lingual posture of the maxillomandibular complex. Delaire has long studied all these aspects, and has published many numbers of articles and constructed a philosophy concerning the significance and interrelationship of the various structures. The results obtained from its application seem to be particularly valid from a clinical point of view, although it has not all been scientifically supported by experimental data. For these reasons, Delaire's primary unilateral and bilateral cheilorhinoplasty procedures are particulary good, as is his secondary gingivoalveoloplsty procedure during the course of the surgical repair of the hard palate. In order to understand Delaire's philosophy, it is necessary to consider the normal and pathologic anatomy of the structures involved in the deformity, the role of some structures, such as nasal septum, musculature, and tongue, and some functions, such as dental occlusion or nasal respiration, which play important roles in maxillary and particularly premaxillary growth. Despite of important concept and meanings, Delaire's philosophy has not been introduced widely to our Korean cleft surgeons yet. So authors will summarize the basic concepts of Delaire's philosophy according to already published literatures and lectures based on our previous treatment outcomes.

A 37 year-old male presented with sudden right proptosis and bilateral nasal obstruction. A huge tumor was noted in bilateral nasal cavities, ethmoid sinuses and central frontal sinus on magnetic resonance imaging. Right posterior frontal sinus wall and bilateral medial orbital wall was destructed by the tumor. Complete resection of the tumor was performed via minimal invasive craniofacial resection. Histopaghologic examination revealed sinonasal undifferentiated carcinoma (SNUC). Cerebrospinal fluid leakage was developed after 2 days of the surgery. On the 5th day, anterior skull base was reconstructed with forearm free flap (FFF). The patient got 6000cGy of radiotherapy and survived in 27 months of follow up.

Objectives: Oral and maxillofacial surgeons must gain mastery of various approaches to the midface due to the increasing incidence, complexity, and severity of presenting midfacial fractures. Unlike in the case of other body parts, the need to preserve facial aesthetics makes it more difficult for the surgeon to select an approach for managing the facial injuries. The midfacial degloving (MFD) approach is a combination of intraoral and intranasal incisions made to access the midface without any external incision. The aim of the present study was to evaluate the efficacy of MFD in maxillofacial surgery and to assess its advantages and complications. Materials and Methods: The MFD approach was used in five cases, with three cases treated with open reduction and internal fixation and two cases operated on for posttraumatic deformity. Nasal dorsum augmentation was completed in three cases and nasal osteotomy was performed in one case. The bicoronal flap technique was combined with MFD for frontal bone augmentation in one case. The intraoperative time required for flap completion and the ease of performing the planned procedures were noted. Postoperative evaluation was done for reduction, aesthetics, function, and complications. Results: Access was excellent for performing all planned procedures. Average time spent for flap elevation and exposure of the midface was 63 minutes. Complications like postoperative swelling, infraorbital nerve paresthesia, and intranasal crusting were all transient. No long-term complications like stenosis of the nose, sneer deformity, or weakness of the facial muscles were noticed. Additionally, no complications were noted when MFD was combined with bicoronal flap. Conclusion: Though the MFD approach is technically demanding and takes more time than other facial approaches, it should be learned and applied by maxillofacial surgeons in selective cases, as it provides complete exposure of the midface without facial scarring.

The sphenopalatine ganglion lies behind the middle nasal concha in the sphenopalatine foramen which connects the fossa to the nasal cavity. It has sympathetic and parasympathetic fibers as well as sensory fibers which innervate the nasal cavity, palate and nasopharynx. Current indications for blockade of the sphenopalatine ganglion include the management of migraine, cluster headache and a variety of facial neuralgias. Blockage of this ganglion can be attempted when more conservative treatments have failed. If the pain relief gained through the procedure is of short duration and the blockage needs to be repeated frequently, then radiofrequency thermocoagulation should be considered. Since the sphenopalatine ganglion lies close to the maxillary nerve, neurolytics can cause facial dysesthesia, radiofrequency thermocoagulation is the preferred method for ganglionotomy. Radiofrequency thermocoagulation of the sphenopalatine ganglion was done for 3 patients who suffered from postherpetic neuralgia, cluster headache, atypical facial pain respectively. Good results were obtained with the exception of the patient suffering from atypical facial pain. Although we were concerned about complications such as epistaxis, none were encountered. However it should be noted that caution must be exercised when repeatedly redirecting the cannula in the sphenopalatine fossa as serious bleeding and pronounced facial swelling may result.

In cases of multiple facial trauma and other specific cases, the anesthesiologist may be asked to convert an oral endotracheal tube to a nasal endotracheal tube or vice versa. Conventionally, the patient is simply extubated and the endotracheal tube is re-inserted along either the oral or nasal route. However, the task of airway management can become difficult due to surgical trauma or worsening of the airway condition. Fiberoptic bronchoscopy was considered a novel method of airway conversion but this method is not useful when there are secretions and bleeding in the airway, or if the anesthesiologist is inexperienced in using this device. We report a successful airway conversion under the aid of both, a fiberoptic bronchoscope and a C-MAC video laryngoscope.

Inverted papilloma of the nose and paranasal sinuses is a rare and benign neoplasm, which has been classified as a true neoplasm by most authors. The most characteristic microscopic feature of inverted papilloma is an increase in thickness and proliferation of the covering epithelium with extensive finger-like inversion into the underlying stroma. Radical aggressive treatment and careful follow up have been advocated in view of the high recurrence rate after inadequate removal and the possibility of malignant transformation. The authors have recently experienced a case of huge inverted papilloma which occupied the left side of nasal cavity, maxillary sinus and ethmoid sinus. A 64 year old female patient who had been suffering from nasal obstruction, hyposmia, headache and frequent nasal bleeding since about 3 years. The patient had had removal surgery as Caldwell-Luc approach with good postoperative effect.

Purpose: The aim of this study is to evaluate the vertical changes of the lip and perioral soft tissue, following orthognathic surgery in skeletal class III patients by a cephalometric analysis of a cone beam computed tomography (CBCT). Methods: A total of 20 skeletal class III patients, who had bimaxillary surgery with Le Fort 1 osteotomy and bilateral sagittal split ramus osteotomy, were included in this study. The surgical plan for maxilla was posterosuperior impaction with the anterior nasal spine, as the rotation center. Further, the surgical plan for mandible was also posterosuperior movement. The soft tissue changes between lateral cephalogram and CBCT were compared. And the correlations between independent variables and dependent variables were evaluated. Results: There were no significant differences of the soft tissues changes between lateral cephalogram and CBCT. Upper lip philtrum length (SnLs), nasolabial angle increased and upper lip vermilion length (LsStms), lower lip length (StmiB'), lower lip vermilion length (StmiLi), lower lip philtrum length (LiB') and soft tissue lower facial height (SnMe') decreased after surgery. Change of SnLs (${\Delta}$SnLs) was influenced by vertical change of menton (${\Delta}$MeV), and change of LsStms (${\Delta}$LsStms) was influenced by upper lip thickness (ULT). Change of StmiLi' (${\Delta}$StmiLi') were influenced by preoperative overjet. Change of StmiB' (${\Delta}$StmiB') were influenced by preoperative overjet, vertical change of lower incisor (${\Delta}$L1V) and horizontal change of posterior nasal spine (${\Delta}$PNSH). Change of LiB' (${\Delta}$LiB') was influenced by ${\Delta}$L1V and ${\Delta}$PNSH. Change of SnMe' (${\Delta}$SnMe') was influenced by ${\Delta}$MeV, horizontal change of upper incisor (${\Delta}$U1H) and horizontal change of lower incisor (${\Delta}$L1H). ${\Delta}$Nasolabial angle was influenced by change of ULT (${\Delta}$ULT). Conclusion: Both soft tissues and hard tissues can be evaluated by CBCT. Posterosuperior rotation of maxillomandibular complex resulted in increase of upper lip philtrum length and nasolabial angle, while the upper lip vermilion length, lower lip philtrum length, lower lip vermilion length, and soft tissue lower facial height showed a decrease.

Purpose: Eczema herpeticum, caused by herpes simplex virus, is an infectious disease involving skin and internal organs. Varieties of physiologic, psychosocial, or environmental stress reactivate reservoir virus which exists in the trigeminal nerve ganglia. Authors report rare cases of nasal eczema herpeticum following corrective rhinoplasty. Methods: First case, 22-year-old female underwent corrective rhioplasty through an external approach in a local clinic. She developed progressive and painful erythema, nodules and vesicles on nose on the 9th day postoperatively. This unfamiliar lesion lead to a misdiagnosis as a bacterial infection, and had accelerated its progress to the trigeminal innervation of the nasal unit. Second case, a 23-year-old female underwent corrective rhinoplasty by external lateral osteotomy. Ten days after the surgery, disruption occurred on the external osteotomy site, and the ulceration gradually worsened. The surgeon misdiagnosed it as secondary bacterial infection and only an antibacterial agent was applied. Results: Both cases were healed effectively without any complication with proper wound dressing and antiviral therapy, and show no sequelae during an 8-month follow-up period. Conclusion: Eczema herpeticum is rare in the field of plastic surgery, but it should be kept in mind that secondary bacterial infections may lead to serious complications such as full-thickness skin loss. Thus, acknowledgement of the patient's past history regarding perioral or intraoral lesion may provide the surgeon with the possible expectancy of eczema herpeticum. Thus, if anyone develops eczema herpeticum, following facial plastic surgery, early diagnosis and immediate proper antiviral therapy will allow fast recovery without serious complications.

[ $\underline{Purpose}$ ]: This study was to evaluate the survival and pattern of failure after radiation therapy of sino-nasal cancer using partial attenuation filer and wedged beams and to help radiotherapy planning of sino-nasal cancer. $\underline{Materials\;and\;Methods}$: Between February 1992 and March 2003, 17 patients with sino-nasal cancers underwent radiation therapy using partial attenuation filter at Dongsan Medical Center, Keimyung university. There were 9 male and 8 female patients. Patients' age ranged from 40 to 75 years (median 59 years). There were 10 patients of maxillary sinus cancer, 7 patiens of nasal cancer. The histologic type was squamous cell carcinoma in 11, adenoid cystic carcinoma in 4 and olfactory neuroblastoma in 2. The distribution of clinical stage by the AJCC system was 3 for stage II, 7 for III and 6 for IV. The five patients were treated with radiation alone and 12 patients were treated with surgery and postoperative radiation therapy. The range of total radiation dose delivered to the primary tumor was from 44 to 76 Gy (median 60 Gy). The follow-up period ranged from 3 to 173 months with median of 78 months. $\underline{Results}$: The overall 2 year survival rate and disease free survival rate was 76.4%. The 5 year and 10 year survival rate were 76.4% and 45.6% and the 5 year and 10 year disease free survival rate was 70.6%. The 5 year disease free survival rate by treatment modality was 91.6% for postoperative radiation group and 20% for radiation alone group, statistical significance was found by treatment modality (p=0.006). There were no differences in survival by pathology and stage. There were local failure in 5 patients (29%) but no distant failure and no severe complication required surgical intervention. $\underline{Conclusion}$: Radiation therapy of sino-nasal cancer using partial attenuation filter was safe and effective. Combined modality with conservative surgery and radiation therapy was more advisable to achieve loco-regional control in sino-nasal cancer. Also we considered high precision radiation therapy with dose escalation and development of multi-modality treatment to improve local control and survival rate in advanced sino-nasal cancer.
