Maxillary double lip

Maxillary Double Lip is a rare congenital anomaly or can be acquired, characterized by a fold of excess or redundant mucous membrane on the maxilla, which is the upper jaw. This condition can affect one or both sides of the upper lip, leading to aesthetic and sometimes functional concerns. Maxillary double lip is more commonly observed in the upper lip but can also occur in the lower lip.

Etiology

The exact cause of maxillary double lip is not well understood. In congenital cases, it is thought to be due to an abnormality in the development of the mucous membrane during embryonic growth. Acquired cases may result from trauma, habitual lip sucking, or as a part of Ascher's syndrome, which is characterized by a double lip in conjunction with blepharochalasis (redundant eyelid skin) and a non-toxic thyroid enlargement.

Clinical Presentation

Individuals with maxillary double lip may present with a noticeable fold of tissue on the inner aspect of the upper lip, especially when the lip is moved or during smiling. This condition is often asymptomatic but can cause concerns related to appearance and, in some cases, speech or eating difficulties.

Diagnosis

Diagnosis of maxillary double lip is primarily clinical, based on the appearance of the lip. Detailed medical history and examination are usually sufficient for diagnosis. In some cases, further investigations may be conducted to rule out associated conditions, such as Ascher's syndrome.

Treatment

Treatment for maxillary double lip is not always necessary, especially if the condition is asymptomatic. For individuals seeking treatment for cosmetic reasons or due to functional impairment, surgical correction is the primary option. The surgery involves excision of the redundant mucosal tissue to restore a more typical lip contour. Postoperative care is important for healing and achieving the desired outcome.

Prognosis

The prognosis for individuals with maxillary double lip who undergo surgical treatment is generally excellent, with significant improvement in cosmetic appearance and any associated functional issues. Complications from surgery are rare but can include infection, bleeding, or asymmetry.
