Pediatric/Craniofacial Surgical Site Infection due to a Preauricular Sinus: A Rare Complication after Craniotomy Masaru Honda, MD, PhD* Takeo Anda, MD, PhD* Hiroshi Mori, MD†

Summary: Wound infection due to a preauricular sinus after craniotomy has not been previously reported. A 71-year-old woman visited our institute with subarachnoid hemorrhage. The aneurysm was surgically clipped with external decompression. Sixteen days after surgery, a focal erythema and discharging were observed at the inferior end of the skin incision. Careful inspection revealed a small pit there, which was diagnosed as a preauricular sinus. After the infection subsided, the sinus was completely excised. Neurosurgeons must be aware of this rare condition and must opt for complete excision to prevent infectious sequelae even if the preauricular sinus is asymptomatic.

Surgical site infection after thyroidectomy: a rare but significant complication.
Surgical site infections (SSIs) after thyroidectomy are rare but can have significant consequences. Thyroidectomy is a clean case, and the patterns for use of prophylactic antibiotics vary. We hypothesized that patient and operative characteristics m

A Surgical Technique for Congenital Preauricular Sinus.
Preauricular sinuses represent a common congenital abnormality in children. Classically, a preauricular sinus manifests as a small opening, usually near the anterior limb of ascending helix. The difficulty in the surgical treatment of preauricular si

Rare complication after VAC therapy in the treatment of tissue defect due to surgical excision of pilonidal sinus.
Pilonidal sinus is frequently managed with surgical incision. If the wound is left open to heal by secondary intention, negative pressure wound therapy (NPWT) is often used to promote healing.

Presentation of preauricular sinus and preauricular sinus abscess in southwest Nigeria.
Preauricular sinus abscess is a common congenital external ear disease. This abscess is usually misdiagnosed because it is commonly overlooked during physical examination. In Nigeria, the prevalence was 9.3% in Ilorin, north central Nigeria This stud

Reconstruction techniques for tissue defects formed after preauricular sinus excision.
Preauricular sinuses are congenital abnormalities caused by a failure of fusion of the primitive tubercles from which the pinna is formed. When persistent or recurring inflammation occurs, surgical excision of the infected tissue should be considered

Intra-abdominal abscess and an intractable abdominal wall sinus forty years after splenectomy is rare, which has not been described previously in the surgical literature. We report the management of a patient who had presented with an intractable sin

A case of subcutaneous hemangioma presenting as a preauricular sinus.
Hemangioma is one of the most common benign neoplasm involved on head and neck. However, cavernous hemangiomas are relatively rare in preauricular sinus space and has rarely been reported around the world. Recently, a 44-year-old female patient came
