Sir,
To complement the case report Nasal dermoid cyst with intracranial extention and an atreticdermal sinus tract by Singh et al, [1] we would like to throw light on the clinical aspect and management of such cases.
The Nasal dermoid sinus cyst [NDSC] anomalies tend to be variable and form no consistent pattern. [2] CT and MRI have become the gold standard in radiological evaluation of nasal dermoid. [1],[2],[3],[4]
Although 50% of nasal dermoids are diagnosed at birth, and 85% before age of 5 years, the average age at operation is 12.3 years. Surgical excision is the definitive treatment. Curettage and other limited procedures are inadequate and will lead to recurrence. It is vital to remove all squamous epithelium and hairs. [5] For NDSC in the absence of an intracranial cyst, the entire tract from the skin to the skull base should be excised. An elliptical incision is taken around the sinus opening. Since the tract passes deep to the nasal bones, medial osteotomies may be required. Alternatively, lateral osteotomies can be performed and the bony nasal vault raised as a unit with the overlying skin. The tract is followed superiorly until the base of the skull, ligated and excised. Should the preoperative investigation show an intracranial cyst, then a combined craniofacial procedure with neurosurgical consultation would be required. [2]
The reported case had two midline swellings over nasal bridge with a punctum. She had telecanthus and had undergone keratoplasty for coloboma of iris. A combined approach by a neurosurgeon and ENT surgeon was done to excise nasal dermoid sinus cyst through frontal craniotomy and open rhinotomy approaches. Histopathologically, it was a trichilemmal cyst.
