Dur- ing the Roman empire it was thought that pores could be unclogged and cleansed by mixing sulfur in mineral baths.

The skin is the largest organ of the The dermis lies below the epidermis and is human body, covering 17–20 square feet. Skin composed of fibrous connective tissue contain- protects underlying tissues and organs from ing collagen and elastin fibers. Collagen provides damage and infection, regulates temperature, mechanical strength, and elastin provides elas- senses pain, protects against dehydration, aids ticity and flexibility.

Complications of parotid gland surgery Damage to the facial nerve, salivary fistula and paraesthesia of the ear lobe (from damage to the greater auricular nerve) is possible. Frey’s syndrome is discomfort, sweating and redness of the skin overlying the parotid gland – related to the innervation of the skin by the para- sympathetic secretory nerve fibres that normally supply the parotid gland. Complications of submandibular gland surgery Damage to the mandibular branch of the facial nerve, the hypoglossal nerve and the lingual nerve is possible.
