A Case of Supernumerary Nostril

Supernumerary Nostril

“…nasal process, a concavity or fissure appears in this area accidentally, and as a result this lateral nasal process is divided into 2 segments; thus, resulting in 2 nostrils [5] .…”

“…Under general anesthesia, an incision was made around the external opening of the supernumerary nostril [5] . Then, the mucous membrane, submucosal tissue and cartilaginous structures in the cavity were excised [6,7] .…”

Supernumerary nostril with a contralateral naso-ocular cleft

“…However, the presence of a naso-ocular cleft on the opposite side would indicate a bilateral involvement. An interesting hypothesis has been proposed by Nakamura and Onizuka [9] to explain the formation and location of supernumerary nostrils and duplications c Late postoperative caused some notching (6 months postoperatively) and may require revision (Fig. 3c).…”

“…Both unilateral and bilateral variants have been described [1,2,3,4,5,9,10,11,12]. These anomalies were initially described by Lindsay [7] and Tawse [14].…”

“…These range from simple excision akin to the technique of fistulectomy [10] to more extensive procedures to shift composite tissue to required areas. These include use of nasolabial flaps [14], external rhinoplasty incisions [1], shifting of alar base and Z plasty [3,9], and recanalizing the nonpatent nostril with a skin graft lining held by stents [2]. We excised the supernumerary nostril as a fistula and shifted the normal ala as a flap as shown in the diagram (Fig.…”
