We report a rare case of advanced metastatic renal cell carcinoma which initially presented to the clinic with back and forehead lumps. Ultrasound imaging of the lumps and later of the abdomen picked up a right renal tumour which led to further computed tomography and bone scans. The bone scan confirmed that the forehead lump was a calvarial metastasis and such a presentation for metastatic RCC...

We report on a new technical method of using an inverted and segmented galea-calvarial flap for simultaneous reconstruction of the frontal sinus and forehead. A 73-year-old man presented with the production of pus at the forehead, in which the frontal sinus had been involved 6 years postoperatively. The patient underwent surgery with our new simultaneous technique. During the 7 years of follow-...

PURPOSE To present a successful case of single-staged total upper eyelid reconstruction after sebaceous gland carcinoma excision by using forehead galeal pericranial flap. OBSERVATIONS An 80-year-old female with a progressively enlarged left upper eyelid mass presented with ocular irritation, blurred vision, and gritty sensation despite topical antibiotics treatment. This multinodular mass in...

Frontobasal injuries and some other diseases of frontal sinuses sometimes require radical surgery with the obliteration of the sinus. A cosmetic correction of the forehead and supraorbital arches has to be performed after such a procedure. Nowadays, there is a wide choice of alloplastic materials on the market. We tried polymethyl methacrylate implants in correction of the exterior appearance o...

This paper investigates the possibility of exploiting facial skin texture as a source of biometric information to facilitate automatic recognition of individuals. Such ability may be particularly important in circumstances when a full view of the face may not be available. The proposed algorithm automatically segments the forehead region and divides it into nonoverlapping patches. Two state-of-...

We prove that two-party randomized communication complexity satisfies a strong direct product property, so long as the communication lower bound is proved by a “corruption” or “one-sided discrepancy” method over a rectangular distribution. We use this to prove new n lower bounds for numberon-the-forehead protocols in which the first player speaks once and then the other two players proceed arbi...

IMPORTANCE Direct transcutaneous resection has been a widely accepted standard for the removal of benign forehead lesions. In recent years, the endoscopic approach has become more prevalent because of its noninvasiveness. To date, only a few studies with limited case numbers have reported on this technique. We report our findings from one of the largest cohorts of patients undergoing tumor rese...
