Critics of comparative risk assessment (CRA), the increasingly common practice of juxtaposing disparate risks for the purpose of declaring which one is the "larger" or the "more important," have long focused their concern on the difficulties in accommodating the qualitative differences among risks. To be sure, people may disagree vehemently about whether "larger" necessarily implies "more serio...

BACKGROUND Injection of dermal fillers is one of the most commonly performed cosmetic procedures. Serious complications from fillers are rare but potentially devastating to patients and physicians. Skin necrosis, such as nasal alar necrosis, is one of the most feared serious complications of dermal fillers, but there is a paucity of literature on the incidence of such events, as well as potenti...

We report a case of an incidental nodular calcification of the alar ligament simulating a fracture in the craniovertebral junction of a previously healthy 24-year-old man. Three-dimensional CT and MR imaging revealed a 7.2 x 7.6 x 4.0 mm nodular calcification in the right alar ligament with normal adjacent bony structures. Serial cervical dynamic radiographs and open-mouth views showed that the...

Stal and Hollier [5] described the nasal support structure as a tripod with lateral displacement in the unilateral cleft lip and loss of tip definition. The cleft side tip defining point is inferiorly displaced with a wide intra alar distance. Early repair with an intra dermal suspension suture with limited alar dissection is advised through an infra cartilagenous incision. The repair has the a...

OBJECTIVE We present 2 cases of trigeminal trophic syndrome treated by surgery. METHODS We performed reconstruction of the ala nasi using a nasolabial flap or paramedian forehead flap in combination with an auricular chondrocutaneous composite graft. RESULTS One case was successfully treated. However, ulceration recurred intermittently in the other case. CONCLUSIONS Although trigeminal tr...

BACKGROUND Nasoalveolar cysts are rare non-odontogenic cysts that occur beneath the nasal alar region. Few cases of bilateral nasoalveolar cysts have been described. CASE PRESENTATION We report a rare case of a 67-year-old Japanese woman with bilateral nasoalveolar cysts who presented to our department with the chief complaint of a swollen left nasal alar base. Panoramic radiography revealed ...

The lateral nasal artery pedicled island flap for the reconstruction of moderately sized alar defects is described. By avoiding distortion of lower nasal landmarks through subperichondrial and subperiosteal dissection over the lateral nasal wall and dorsum, we were able to achieve satisfactory results with excellent color, texture, and symmetry matches in three patients over a 2-year period at ...

BACKGROUND Secondary rhinoplasty after a cleft lip repair remains a significant challenge. We have developed a technique in which resorbable plates are used to support the cleft alar cartilage to minimize relapse. There are few guidelines by which one can objectively assess the outcome of cleft rhinoplasty over time. This study attempts to demonstrate a means by which the symmetry and form of t...
