Proboscis Lateralis: A Rare Malformation of the Nose its Genesis and Treatment

Lateral nasal proboscis

“…The association of lateral nasal proboscis with anomalies of the eye pinpoint the 4th~7th weeks of foetal life, the earliest period of malformations, as the period during which the noxious exogenic factor, so far unknown, operated in this particular case. According to Biber (1949) the lateral nasal process is responsible for the formation of proboscis in cases associated with ipsilateral nasal abnormalities as in the present case. As to the management, Biber (1949), Bishop (1964, and Kirkpatrick (1970), have advocated reconstructive surgery after the nasal growth is complete, otherwise the normal side may outgrow the affected side.…”

“…Surgery is best undertaken before the school-going age so as to spare the child the psychological trauma. Most authors including Blair and Brown (1931), Biber (1949), Young (1949), Smith (1950, Bishop (1964), and Kirkpatrick (1970) seem to agree that the proboscis itself forms an ideal material for reconstruction purposes. In keeping with the above views, surgery in this case was deferred to a later date.…”

Bilateral Nasal Proboscis: Associated with Unilateral Anophthalmia, Unilateral Diffuse Pigmentation of the Conjunctiva, and Anomalies of the Skull and Brain

“…The early literature has been reviewed by Grunberg (1909), Zausch (1926), Berblinger (1928), and Stupka (1938). Cases have been described also by Blair and Brown (1931), Biber (1949), Smith (1950), Cottle et al (1956), Meyer (1956), and Bremer (1956). The case presented here had a lateral nasal proboscis on each side; we have found no reference to such an instance and thus consider it worth while reporting.…”

“…[1][2][3][4] ; no external nose is present and no nostrils, but above each eye a proboscis projects horizontally, forward, and medially. The two probosci are very similar in form, the resemblance extending even to minor folds and depressions.…”
