IMPORTANCE Adenoid cystic carcinomas (ACCs) are relatively rare tumours, notorious for wide local infiltration and perineural spread. Perineural extension commonly occurs along branches of the trigeminal and facial nerves, and its presence represents a poor prognostic factor with implications for treatment approach. OBSERVATIONS We report the case of a 61-year-old female presenting with worse...

OBJECTIVES/HYPOTHESIS Evaluate the difference of the incidence in clinical Frey syndrome in studies comparing classical parotidectomy and parotidectomy with superficial musculoaponeurotic system (SMAS) flap elevation and suturing through meta-analysis methodology. STUDY DESIGN Meta-analysis of controlled studies with and without SMAS flap. METHODS Database search with the following key word...

Plexiform neurofibromas are benign tumors that tend to occur in patients suffering from neurofibromatosis type 1 (NF-1). This report addresses a rare case where the tumor affected the parotid gland, deriving almost exclusively from the peripheral portion of the facial nerve. A 6-year-old male was referred to us complaining about a gradually enlarging swelling over the right parotid area. Imagin...

Studies on a quantitative separation and analysis of chloroplastic matter by different investigators have revealed that chlorophyll is held by chemical forces on proteinaceous matter. This matter, named phyllochlorin by MESTRE (17), chloroplastin by STOLL (37), photosynthin by FRENCH (8), and chloroglobin by RABINOWITCH (21), is presumably identical with the substance composing the stroma of ch...

BACKGROUND Frey s syndrome or Gustatory sweating was first described by Baillarger in 1853. Lucie Frey had described a patient as "auriculotemporal syndrome" in 1923. The explanation for this symptom has been an aberrant regeneration of postganglionic parasympathetic fibers feeding the parotid gland that are severed during parotidectomy. After parotidectomy, these cholinergic parasympathetic fi...

OBJECTIVE Presentation of a case of perioral Frey syndrome. DESIGN Case report. SUBJECT A 72-year-old woman with hyperhidrosis around the mouth and chin. RESULTS This patient suffered from bilateral perioral gustatory sweating following a mandibular osteotomy; such a case has not previously been described. Possible pathophysiological hypotheses are discussed in relation to the anatomy and...

OBJECTIVE To evaluate the incidence of Frey syndrome (auriculotemporal nerve syndrome) after parotidectomy with and without placement of a subcutaneous implant and to examine the relationship between different implants and postoperative wound complications (hematoma, seroma, salivary fistula). DESIGN A prospective nonrandomized controlled trial. SETTING A primary care and referral universit...
