OBJECTIVETo study the coordination of facial soft tissue in Angle's Class I, II1, III malocclusion, providing reference for the clinical practice.

METHODS60 lateral cephalometric radiographs of three classes of Angle's malocclusion were included. 13 measurements were analyzed by SPSS 10.0.

RESULTSProtrusion of the upper and lower lips increased in Angle's II1 comparing with Angle's I and protrusion of the upper lip was larger than the lower lip, no difference was found in the facial convexity. Increase of upper lip inclination and underdevelopment of maxillary in Angle's III comparing with Angle's I. No significant different was found in the form of lower lip, soft tissue facial angle and Z angle. Comparing Angle's II1 with Angle's III, every measurements were significantly different except upper lip inclination, nasolabial angle, representing the formation mechanism of malocclusion.

CONCLUSIONSome differences were found in form and position of lip in three classes of Angle's malocclusion. However, the deformity was not obvious in Angle's II1 and Angle's III because of compensation mechanism. Nasolabial angle only reflected change of upper lip, but could not reflect characters of facial profile.

Based on the three books of - (1931), - (1940) and - (1955) written by Mr. -, the classification of facial diseases as well as the records and evolution process of Chinese and western disease names are summarized and analyzed to discuss Mr. -'s understanding of facial diseases in different periods. Through the systematic analysis and comparison in the trilogy of acupuncture and moxibustion, the characteristics of syndrome differentiation and diagnosis-treatment of acupuncture-moxibustion treatment for facial diseases by Mr. - are summarized, including clinical syndrome differentiation and treatment, which is adjusted with syndrome changes; simplified selection of acupoints, with attention on empirical acupoints; the strength of acupuncture is based on efficacy; acupuncture and moxibustion has specific indication; combination of acupuncture and medication could bring out the best in each other.

Ota's nevus is mongolian spot-like macular blue-black or gray-brown patchy pigmentation that most commonly ocurrs in areas innervated by the first and second division of the trigeminal nerve. Acquired, bilateral nevus of Ota-like macules (ABNOM) is located bilaterally on the face, appears later in life, is blue-brown or slate-gray in color. It is not accompanied by macules on the ocular and mucosal membranes. There is also debate as to whether ABNOM is part of the Ota's nevus spectrum. We report an interesting case of ABNOM associated with Ota's nevus. A 36-yr-old Korean women visited our clinic with dark bluish patch on the right cheek and right conjunctiva since birth. She also had mottled brownish macules on both forehead and both lower eyelids that have developed 3 yr ago. Skin biopsy specimens taken from the right cheek and left forehead all showed scattered, bipolar or irregular melanocytes in the dermis. We diagnosed lesion on the right cheek area as Ota's nevus and those on both forehead and both lower eyelids as ABNOM by clinical and histologic findings. This case may support the view that ABNOM is a separate entity from bilateral Ota's nevus.

A 3-year-old boy presented with bluish patch and scattered blue spots on the left side of his face. After several sessions of laser treatment, the azury patch in the periorbital area became even darker. Histopathology showed many bipolar, pigment-laden dendritic cells scattered in the papillary and upper reticular dermis. Immunohistochemically, these cells were positive for S100, SOX-10, melan-A, P16, and HMB-45. The positive rate of Ki-67 was less than 5%. Finally, the lesion was diagnosed with nevus of Ota concurrent with common blue nevus. Therefore, for cases of the nevus of Ota with poor response to laser treatment, the possible coexisting diseases should be suspected.

Pus overflow from patent's fistula belew the left face near mandibular angle 2 years agowith a little pain. Symptoms relieved after oral antibiotics.

Subcutaneous emphysema is the local tissue swelling caused by the gas entering the subcutaneous tissue through the tissue gap. Although subcutaneous emphysema is usually a nonfatal and self-limited disease, in severe cases, the gas may spread to the neck, mediastinum and chest, resulting in mediastinal emphysema and other serious complications. This article reviews the etiology, pathogenesis, clinical manifestations, diagnosis, differential diagnosis of subcutaneous emphysema related to dental therapy,and operations that may cause subcutaneous emphysema in stomatology department,as well as the treatment and prognosis of subcutaneous emphysema, with a view to providing some references for dentists.

The infratemporal fossa abscess is an irregularly shaped cavity, situated below and media to the zygomatic arch. It consists of masseter and nervus vascularis, etc. Comparatively speaking, the low position of the infratemporal fossa has almost freed the patient from dental, nasal,ocular and aural source of pain. So facial acupuncture is more likely to cause the infection. But it is also possible that the patient get cryptogenic infection of maxillofacial cavity, the treatment of which needs further study.
