The lateral rhinotomy signifies only an incision and not on operation and a lateral rhinotomy incision with osteotomy of the nasal bones provides access to the entire nasal cavity and maxillary, ethmoid, and sphenoid sinuses as well as the frontal sinus if the floor is removed, permitting removal of benign lesions at these sites and en bloc resection of the ethmoid labyrinth and the party wall between the nasal cavity and antrum with infiltrating tumors. The authors treated a tumor patient and a midfacial bone fracture patient via lateral rhinotomy approach and had a good result. So we report the cases with literature review.

The primary malignat melanoma of the nasal cavity and paranasal sinuses is extemely rare and accounts for only between 0.6 and 2.5% of the total 'number of malignat melanoma at all sites. In the nose, the left side is involved in 60% of cases and the most frequent site is the septum followed by the inferior and middle turbinates. In the sinuses, the maxillary sinus is the site of origin in 80% of cases, followed by ethmoid sinus. The tumors are sessile or polypoid, with variable color such as pink. white, brown or black. Of all tumors, 10~30% are amelanotic, requiring special stains for melanin. When primary site of melanoma is mucosal origin. treatment of primary lesion is often hampered by anatomic retrictions and large size, which results from the delayed diagnosis caused by their location. We report 4 cases of primary malignant melanoma of nasal cavity with review of literature.

In recent years the immunocompromised population has increased rapidly to include people with acquired immune deficiency syndrome (AIDS), drug abusers, and transplant patients. Accordingly, the incidence of intracranial fungal infection has increased. Our institution experienced 2 cases of internal carotid artery (ICA) occlusion due to invasion of the cavernous sinus by an intracranial fungal infection. The first case was a 60-year-old man who presented with headache, eye pain, conjunctival injection, right-sided diplopia, and blurred vision. Infected tissues within the frontal and ethmoid sinuses were removed via bifrontal craniotomy and endoscopic sinus surgery through the Caldwell Luc approach. The second case was a 63-year-old woman who developed right-sided facial pain after a tooth extraction. The infection was not controlled despite continuous use of antifungal agents, resulting in death from sepsis. We believe that when intracranial fungal infection is suspected in a patient with orbital symptoms and a focal neurologic deficit, immediate angiographic investigation of possible ICA occlusion is warranted. Aggressive treatment with antifungal agents is the only way to improve prognosis.

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: Anatomical variations of the external nasal wall are highly important, since they play a role in obstruction or drainage of the ostiomeatal complex and ventilation and can consequently elevate the risk of pathological sinus conditions. This study aimed to assess anatomical variations of the nasal cavity and ethmoidal sinuses and their correlations on cone-beam computed tomography (CBCT) scans. Materials and Methods: This cross-sectional study evaluated CBCT scans of 250 patients, including 107 males and 143 females, to determine the prevalence of anatomical variations of the nasal cavity and ethmoidal sinuses. All images were taken using a New Tom 3G scanner. Data were analyzed using the chi-square test, Kruskal-Wallis test, and the Mann-Whitney test. Results: The most common anatomical variations were found to be nasal septal deviation (90.4%), agger nasi air cell (53.6%), superior orbital cell(47.6%), pneumatized nasal septum(40%), and Onodi air cell(37.2%). Correlations were found between nasal septal deviation and the presence of a pneumatized nasal septum, nasal spur, and Haller cell. No significant associations were noted between the age or sex of patients and the presence of anatomical variations (P>0.05). Conclusion: Radiologists and surgeons must pay close attention to the anatomical variations of the sinonasal region in the preoperative assessment to prevent perioperative complications.

Pneumatisation of the maxillary sinus (MS) is variable. The archived cone-beam computed tomography file of a 54-year-old female was retrospectively evaluated anatomically. Nasal or retrobullar recesses of the MSs (NRMS) were found. The MSs were bicameral. NRMSs extended from the postero-lateral chambers of the MSs into the lateral nasal walls. The right NRMS was reached superior to the middle turbinate and the ethmoidal bulla was applied on its anterior side. The left NRMS had two medial pouch-like ends, one beneath the ethmoidal bulla and the other on the anterior side of the basal lamella of the middle turbinate. Additional anatomical findings were the uncinate bulla, infraorbital recesses of the MS, maxillary recess of the sphenoidal sinus, and atypical posterior insertions of the superior nasal turbinates, maxillo-ethmoido-sphenoidal and ethmoido-sphenoidal. The NRMS is a novel finding and could lead to erroneous endoscopic corridors if not documented before the interventions.

Myxomas are rare benign tumors that originate from mesenchymal tissue. They usually develop in the atrium of the heart, the skin, subcutaneous tissue, or bone. Involvement of the skull base with an intracranial extension is very rare and not well-described in the literature. We report a rare case of primary intracranial ossifying myxoma arising from the anterior skull base and mimicking a huge chondrosarcoma, and we review the relevant literature.

Intracranial schwannomas preferentially arise from the vestibular branch of the eighth nerve, and rarely from the trigeminal nerve, facial nerve, and lower cranial nerves. Anterior cranial fossa schwannomas are extremely uncommon and few details about them have been reported. The patient was a 39-year-old woman whose chief complaints were anosmia and frontal headache for 2 years. The gadolinium (Gd)-enhanced magnetic resonance imaging (MRI) showed an extra-axial mass from ethmoid sinus to right frontal base region near the midline, with solid enhancement in lower portion and multicystic formation in upper portion. The tumor was totally resected via basal subfrontal approach. At operation, the tumor had cystic portion with marginal calcification and the anterior skull base was destructed by the tumor. The olfactory bulb was involved, and the tumor capsule did not contain neoplastic cells. The histopathological diagnosis was schwannoma. We report a rare case of anterior cranial fossa schwannoma with literature review.

Osteomas are most often located in the femur, tibia, humerus, spine, and talus. They are rare in the skull. Osteomas in the head and neck regions are benign bone neoplasms usually found in the frontoethmoid area. The developmental theory postulates that osteomas develop at the sites of fusion of tissues different embryological origin such as occur at the junction of the embryonic cartilaginous frontal and ethmoid bones. Trauma and infection have also been implicated as causative factors, but many patients with osteoma deny any preceding history of these. Osteomas are usually produce symptoms primary to cosmetic problems and secondary to pressure on adjacent structures. The objects of this study are from a 5-year period of April of 2002 to April of 2007, consisting of 48 male patients and 52 female. There were 33 cases of frontal bone osteomas, 5 cases of madibular bone osteomas, 5 cases of occipital bone osteomas, 6 cases of symptomatic paranasal sinus osteomas, 48 cases of asymptomatic paranasal sinus osteomas, and 3 cases of mastoid osteomas. We reviewed medical records of patients to find out their presentations, diagnostic considerations, therapeutic options, and outcomes. Patients were followed up six months postoperatively on the average. The authors experienced 48 cases of osteoma in the head and neck lesion, which were removed via direct approach or endoscopic approach. The 100 cases who came to the hospital with or without symptoms after diagnosis healed completely without sequelae. During the follow-up periods, excellent functional and cosmetic results were observed with an inconspicuous scar. There was no specific complications related to this procedure. Results of surgery in most cases were satisfied. We discussed the surgical procedure and the characteristics of the osteomas, and we report several cases with the review of literatures.

Background: Lateral rhinotomy and medial maxillectomy, an en bloc resection of the medial maxillary sinus, ethmoid sinus with the lamina papyracea, medial orbital floor, and lacrimal fossa-duct, have been advocated for lateral nasal wall neoplasms as a standard approach method. Objective: This report was conducted to investigate the clinical efficacy of lateral rhinotomy and medial maxillectomy for lateral nasal wall neoplasms. Materials and Methods: We retrospectively analyzed clinical data of 31 patients who were treated at department of otolaryngology-head and neck surgery, Catholic university of Korea, school of medicine between 1990 and 1996. Results: Twenty five patients had benign lesions(80.6%). By far, the largest percentage was inverted papillomas(80%, 20/25). Of the six malignant lesions(19.4%), 33.3%(2/6) was squamous cell carcinoma and other lesions were metastatic renal cell carcinoma, adecarcinoma, transitional cell cacinoma, and hemangiopericytoma. There were a 4% recurrence for benign tumors(1/25), 5% especially for inverted papilloma(1/20), and 50% for malignant neoplasms(3/6). The overall complication rate was 9.7%. Conclusion: Despite the various approach for treatment of lateral nasal wall neoplasms including inverted papilloma, we continue to advocate a lateral rhinotomy and medial maxillectomy as the treatment of choice.
