The author has recently experienced a case of two salivary stones in the submandibular gland on the right side. A 35 year old man visited the department of Otolaryngology Chosun University, on 4 August 1988 with complaints of walnut sized,"tender swelling on the right submandibular region and mastication difficulty. These symptoms have been graudally developed and aggrevated for past 2 years. Physical examination was not revealed fistula or inflammation on the posterior portion of the right side mouth floor. Plain A-P and right lateral mandibular X-ray views and sialography revealed a large, oval shaped radio-opaque density on the right submandibular region. Through an external approach under the general anesthesia, extirpation of the gland with stone removal was done. The removed two stones were contact with each other. Two stones were 1.5 x 1.5 x 1 cm. and 1 x 1 x 1 cm. in each size, 4.0 gm in weight, grayish-white in color, and the chemical composition of the stones were principally calcium phosphate. The extirpated gland was 3 x 2 x 2 cm in size and revealed chronic sialoadenitis on biopsy.

The term mucocele was introduced by Rollet in 1896 and Onodi gave the first histologic description in 1901. Paranasal sinus mucocele is the slowly expanding benign lesion which can occur as a result of trauma and spontaneous obstruction of sinus ostium or ostial tract. Mucoceles most frequently ahse from the frontal sinus and anterior ethmoid air cells, Presenting with proptosis, frontal headaches and reduced ocular mobility, especially on upward gaze. Since it may destruct the adjacent bony structure by pressure, early diagnosis and proper treatment are necessary. Recently we experienced on huge mucocele involving frontal and anterior ethmoid sinus and expanding onto left orbit, which was treated with endoscopic surgical procedure.

Neurilemmoma is a relatively rare benign tumor which may be derived from nerve sheath of the peripheral and cranial nerve, and characterized by solitary occurrence, with sharp demarcation and encapsulation. In spite of their rarity, a high proportion of these growth are situated about the head and neck. About 30% of the disease is found in the head and neck region and the most common single site of origin is known to be the acoustic nerve. Thus, described that case involving the upper cervical spine is rare. We recently had the opportunity to care for a man with a cervical spinal neurilemmoma including affected nerve root at C3 level. When the tumor is derived from a root which is assumed to be important for extremity functions, it is still controversial whether that nerve root should be totally resected. A review of the current literature and intraoperative management will be presented to further define these concepts.

Aplasia or agenesis of the salivary gland is an uncommon disorder. Unilateral aplasia of the submandibular gland is an extremely rare disorder. Salivary gland aplasia may occur either in isolation or in association with other developmental anomalities, such as atresia of the lacrimal pucta, mandibulofacial dysostosis or congenital malformations of the temporomandibular component. Clinically, patients may be asymptomatic or may present with dryness of the mouth, difficulty in swallowing, and dental caries. The authors experienced two cases of incidentally detected unilateral aplasia of the submandibular gland demonstrated by computed tomography. So we present this cases with review of literatures.

Malignant melanoma aries from melanocyte, which has the ability to synthesize the pigment melanin. Melanocytes are derivations of neural crest cells and widely distributed throughout all cutaneous and mucosal surfaces. Overall, 20% of all malignant melanomas arise in the head and neck, of which only 10% affect the mucous membranes. Less than 1% of all malignant melanomas affect the nasal cavity. The authors experienced a case of primary malignant melanoma originated in left nasal cavity and paranasal sinus, and the patient had been treated by wide excision of the tumor with Weber-Furguson approach and postoperative irradiation. We report a case of primary malignant melanoma on the nasal cavity and paranasal sinus of 49 years old female patient with review of literature.

The author experienced 110 patients of otitis media with effusion from Jan., 1985 to Dec., 1987 and the results were as follows; 1) The sex distribution showed 64 male cases and 46 female cases and bilateral effusion was more frequent than one side. 2) The 67 patients were attacked in spring and winter (61 %). 3) In the preoperative tympanogram, there were 10 %with type A, 77 %with type B and 13 % with type C. 4) The rhinitis and sinusitis (56 %) were considered as the main preceeding diseases. 5) Drum retraction was seen in 53 % and turbid drum without retraction in 18 %. 6) The nature of middle ear fluid was 48 % serous exudate, 36 % mucoid exudate, 2 % purulent exudate and 14 % scanty or no fluid. 7) The 56 patients were treated with myringotomy and ventilation tube insertion.

The prognostic significance of the squamous cell carcinomas of the larynx and the hypopharynx have been evaluated to identify those features associated with aggressive biologic behavior according to the immunologic and histologic characteristics. For determining prognostic indicators, the authors performed immunohistochemical staining of epidermal growth factor receptor(EGFR) in 32 cases of squamous cell carcinomas of the larynx and the hypopharynx. The results were obtained as follows '. 1) The positive rate of EGFR expression was 96.6% and rate of EGFR overexpression was 50%. 2) There was no significant statistical correlation between EGFR expression and clinicopahtological parameters such as primary sites of tumor, primary tumor stage, nodal stage, distant metastasis, clinical staging and histopathological grade.

The fourth branchial pouch sinus is a developmental anomaly which most freqently manifests itself by recurrent episodes of neck abscess or acute suppurative thyroiditis. The most common developmental anomalies of the branchial apparatus are second cleft remnant, which constitute almost 95% of all anomalies. The remaining 5% are comprised almost exclusively of first and third arch remnants. So the fourth arch remnants are exceedingly rare. A high index of suspicion, combined with barium swallow pharyngogram and computed tomography scan can aid in diagnosis. Complete excision of the entire epithelial tract combined with ipsilateral thyroid lobectomy remains the mainstay of treatment. Authors experienced a case of lateral neck mass which was pathologically presumed to be the fourth branchial pouch sinus. We report this case with the related literature.
