Purpose: Congenital sinus of the upper lip is extremely rare and only 3 cases have been reported domestically. We report a case of congenital sinus of midline upper lip, which was found in an adolescent patient. Methods: A 14-year-old girl presented with a small pit on midline of the upper lip, which was visible at birth. The patient had never been treated for the congenital sinus because it was asymptomatic. Surgical excision under local anesthesia was performed. Results: The sinus had a tract extending into 5 mm posteroinferior and had not penetrated the oral cavity. Histological examination showed a fistulous tract lined by keratinized squamous epithelium. After complete excision, there was no recurrence and we obtained a satisfactory cosmetic result. Conclusion: Congenital sinus of the midline upper lip is extremely rare. This is a special case that is reported because it did not cause symptoms for the patient until she reached adolescence.

Arthrocentesis is a simple, less invasive, inexpensive, and highly efficient procedure for closed lock of the temporomandibular joint with regard to the lack of recurrence of symptoms during extended periods of follow-up and significiant improvement in pain and jaw function. It can be performed under local anesthesia. Arthrocentesis closed lock provide sustained normal joint function and marked pain relief. This study is the clinical outcome of arthrocentesis for closed lock of the temporomandibular joint. 160 patients(169 joints) who had experienced sudden-onset, persistent limited mouth opening were the subjects of this study. Arthrocentesis of the upper compartment of the affected TMJ was performed using normal saline. As results, at 3-60 months postarthrocentesis maximum mouth opening(MMO) had increased from mean of 27.7mm to 43.5mm, contralateral movements(CLM) from mean 5.74mm to 9.55mm, midline deviation during mouth opening from mean 3.04mm to 0.69mm. In 130 cases there was a history of joint noises, in 52 cases all noise had ceased after procedures.

Thyrotomy is very useful surgical procedure for laryngeal lesions; however, the web-formation at the anterior part of vocal cords is a frequent troublesome sequel of this procedure. Since the anterior commissure is not injured in Hayashi's hemithyrotomy, a web never results from this procedure. But the intralaryngeal exposure is too small to perform the surgery in this method. Partial thyrotomy was deviced as a new surgical technique to the glottic subglottic lesion. In partial thyrotomy, surgical procedure can be easily carried out under local anesthesia, in a wide field. This procedure has no side effects such as the web-formation at the anterior commissure, nor dyspnea after the surgery.

Adenoid cystic carcinoma that is found most frequently in the salivary gland is an extremely rare malignant tumor in middle ear and is a slow growing one with a characteristic tendency of recurrence after surgical removal. Recently we experienced a case of this rare adenoid cystic carcinoma arising from middle ear of 30 year old male patient. The patient complained of hearing impairment for two years duration and pulsating tinnitus for two weeks duration in the right ear. Under the local anesthesia, throgh exploratory tympanotomy, a grayish white mass measuring $1.5\times$1.5$\times$1mm in the hypotympanic portion was removed out and a adenoid cystic carcinoma was verified histopathologically.

Pressure pain thresholds are routinely used in orofacial pain research to evaluate the response of deep orofacial tissues to mechanical stimulation. Like other psychophysical measurements, however, this technique must stimulate cutaneous tissues before stimulating deeper tissues. This study aimed at evaluating the influence of the cutaneous hypoesthesia on the pressure pain threshold in 30 healthy volunteers. PPTs were determined with electric pressure algometry over masseter, temporalis anterior, sternocleidomastoid, and trapezius muscle before and after skin hypoesthesia. A local anesthetic cream and a control cream were applied following a placebo-controlled double-blind design and PPTs were reassessed. Two examiners measured PPTs two times on each muscles, randomly. And the EMG activity of all muscles were measured to evaluate the relationship with PPTs. The collected data were processed by SAS/STAT program. The obtained results were as follows : 1. There were a tendency to increase PPTs after than before cutaneous hypoesthesia, but, there were no significant difference statistically. 2. PPTs were consistently higher in anterior temporalis than in masseter muscle. 3. In all occasions, PPTs were higher in males than in females(p<0.001). 4. A statistically significant correlation was obtained from values of intra-examiners and inter-examiners in all measured muscles. 5. A significantly positive correlation was not found between PPT and functional EMG activity.

Neurofibroma are slow growing benign tumors arising from the neurilemal sheath (Schwann cells) and fibroblasts of the peripheral nerve. This benign tumor may occur as a solitary lesion or as a part of the syndrome of neurofibromatosis. The neurofibroma of oral tissues is rare in otolaryngologic field and usually presents as a firm, elevated, nonpainful lesion that shows the usual histologic findings of a neurofibroma or neurilemmoma. Recently, we have experienced a neurofibroma arising from the tongue in a 54 year old female and removed successfully under local anesthesia. No evidence of recurrence has been observed up to date.

Angiofibroma in otorhinolaryngologic field is rare, highly vascular and non-metastatizing benign tumor. It was noted as histologically benign but clinically malignant tumor because of the anatomical site, severe bleeding in surgery and recurrence in incomplete removal. It occurs almostly in nasopharynx of adolescent males. Recently, the authors have experienced a very rare case of angiofibroma which occupied the nasal septum in a 37-years-old-male with complaints of nasal obstruction and frequent nasal bleeding. The tumor mass was removed surgically through intranasal approach under local anesthesia. We report our case with review of current literatures.

We report a case of actinomycotic infection in epiglottis. Actinomycosis in the head and neck area is relatively rare but extremely rare in the larynx. A 63-year old man presented with continuous discomfort of the throat while swallowing. He had a history of oral injury caused by a fish bone a few weeks prior. Upon Examination with a flexible laryngoscope, a whitish round mass was noted at the lingual surface of the epiglottis. Under local anesthesia, a punch biopsy was performed and showed the typical features of actinomycosis. The mass was removed using a Diode laser under suspension laryngoscope. Additive oral antibiotic therapy was done for 2 weeks. No definite recurrence was noted at the operation site and the patient is now free of disease.

Malignant skin tumors and precancerous lesions have a predilection to be located in the nasal dorsum or sidewall. Although invasive reconstructions have been presented, no simple and suitable method has yet been reported for this area. The flap presented herein, named the lateral nasal advancement flap, is designed on the adjacent lateral region of the sidewall or nasal dorsum and advanced in the medial direction. Two Burow's triangles are removed in the upper and lower portions of the flap: the upper triangle along the nasofacial sulcus and the lower triangle along the nasofacial sulcus and/or the alar groove. Excellent results were obtained in the two clinical cases described in this report. Neither a trap door deformity nor dog-ears developed in either case. The postsurgical scars followed the aesthetic lines and became inconspicuous. A distinct angle was formed in the nasofacial sulcus without anchor sutures. This surgical procedure is technically simple and is performed under local anesthesia. Although the flap is a cheek-based advancement flap, postsurgical scars do not remain in the cheek; instead, they are located in the nasofacial sulcus and alar groove. The lateral nasal advancement flap is recommended for reconstruction of the nasal sidewall and dorsum.

After introduction of operating microscopes and laser devices in the 1960's, monumental innovation for had been achieved in laryngeal microscopic surgery. The development of high-tech operating devices made the laryngeal surgery less invasive and more precise. There were long histories until developing of the modem instruments and surgical techniques. The simple oral mirror introduced by Bozzoni in 1807 is the beginning of laryngoscope. In 1859 Green carried out the laryngeal operation under direct view of larynx. The appearance of local topical anesthesia on throat had contributed to laryngeal surgery coming into wide use. Killian and Jackson made much contribution to developing the design of laryngoscope. After that, modem laryngeal surgery have been developed with development of the stabilizing holder of laryngoscope and optical devices. We propose carefully the direction of the development of the laryngeal surgery by historical consideration of laryngeal surgery and instrumental development.
