It frequently consists of skin, hair follicles, and sweat glands, while other commonly found components include clumps of long hair, pockets of sebum, blood, fat, bone, nail, teeth, eyes, cartilage, and thyroid tissue.
The tract of the congenital dermal sinus must then be explored and excised, with intradural lesions dissected. [4] If not all epithelial tissue is removed, there is a possibility for the dermoid cyst to reoccur and require further operation. [4] Further operations are limited by postoperative and post-infection scarring. [4]

Pilonidal sinus (PNS): is a sinus tract, or small channel, that may originate from the source of infection and open to the surface of the skin. [10] Material from the cyst drains through the pilonidal sinus. A pilonidal cyst is usually painful, but if it is a draining sinus, the pressure is relieved and patient might not feel pain.
Cysts treatment is limited to surgical removal for the majority of cysts. There are two techniques used to manage cysts with the deciding factor being the size of the cyst. [8] Enucleation—removal of the entire cyst. A mucoperiosteal flap is raised overlying the cyst and the entire cyst subsequently removed.

Currently, it comprises four approaches, namely rhinoplasty, septoplasty, sinus surgery, and turbinoplasty, targeted at different sections of the nasal cavity in the order of their external to internal positions.

A CT scan shows a solid mass of Tornwaldt's cyst and MRI shows a glass-shaped lesion with fluid on the upper part of the posterior nasopharyngeal wall. Additionally, a cystic mass in the upper part of the nasopharyngeal wall and mucopurulent discharge from upper part of the mass can be seen on nasal endoscopy. Among them MRI is the best for ...
