Absence Of Columella Research Articles

Notothylas flabellata (Notothyladaceae, Anthocerotopyta), an Afro-American hornwort newly found in Mexico

Notothylas flabellata is reported for the first time in Mexico and North America, previously known only from Argentina in the American continent. This species was originally described from Africa. This species is characterized by absence of columella, dark brown to black tuberculate spores with distal hump-like globular projections and sub-quadrate to rectangular pseudoelaters with brown spiral-annular bands. In North America, this species might be confused with N. breutelii, but it can be differentiated by the presence of a columella in N. breutelii, and spore and pseudoelater ornamentation. Light microscopy photographs of N. flabellata and N. breutelii are provided. The new record increases the species number of Notothylas in North America to four.

Single Surgeon's Experience in Repair of Median Cleft Lip: A Case Series of 5 Median Craniofacial Dysplasia Patients.

Median craniofacial dysplasia is a rare congenital anomaly with a broad spectrum of severity, which can be classified as hypoplasia, dysraphia, and hyperplasia, depending on the involved tissue amount. A retrospective chart review was performed of patients with median craniofacial dysplasia who underwent repair of the upper lip median cleft between January 2013 and February 2020. The median cleft of the upper lip was present in 5 cases. The average age at operation was 11 months. Two patients had a median notch in the vermilion, 2 patients had an incomplete median cleft lip, and 1 patient had a complete median cleft lip with the absence of columella, prolabium, and premaxilla. A variety of surgical correction was performed for each case, including simple rhombus-shaped excision, modified version of straight-line repair, and columella reconstruction using an intranasal dorsal flap and bilateral cleft margin flaps. Each case needs to be carefully assessed with individualization for appropriate surgical treatment.

Congenital Heminasal Hypoplasia with an Intranasal Cyst and Its Management by Subnasal Rotation Flap

ABSTRACTVarious congenital nasal deformities can occur because of the complexities of the developmental process. These conditions range from partial deformities of the nose (such as isolated absence of the nasal bones, absence of columella, absence of the septal cartilage, and absence of vomeral bone) to complete absence of the nose. Congenital heminasal hypoplasia is an extremely rare defect of embryogenesis. We present a case of 25-year-old lady with congenital heminasal hypoplasia associated with intranasal cyst. Computed tomography (CT) scan revealed gross septal deviation to left, rudiment left lateral wall of the nose, rudiment left external nasal framework, and intranasal cyst. Functional septorhinoplasty was done with subnasal rotation flap technique to gain airway on both sides of the nose.How to cite this articleDevasamudra CR, Sagar NJ, Jayaraju RM.

Myxomycetes of Maharashtra: two new species of Diderma Pers

The present paper provides the description and illustrations of two new species of Diderma (D. non-columellata sp. nov. and D. physarinum sp. nov.) that are characterized by the absence of columella in the first instance and the presence of a large columella bearing a number of peg-like protuberances running through the sporangial cavity up to the peridium in the second instance. The latter condition is similar to what is found in the genus Physarina respectively.

A case of congenital heminasal hypoplasia with an intranasal cyst: An extremely rare occurrence

Various congenital nasal deformities can occur because of the complexities of the developmental process. These conditions range from partial deformities of the nose (such as isolated absence of the nasal bones, absence of columella, absence of the septal cartilage, and absence of vomeral bone) to complete absence of the nose. Congenital heminasal hypoplasia is an extremely rare defect of embryogenesis. We present a case of congenital heminasal hypoplasia with an associated dacryocystocele and intranasal cyst. The treatment of congenital dacryocystocele remains controversial. The majority of researchers recommend an initial treatment plan that does not include surgical intervention. Surgical reconstruction of the external nose and inner cavities can be delayed at least until the preschool years, when facial development is nearly complete.

Median cleft of the upper lip: report of cases

Background: Median cleft of upper lip is an uncommon facial anomaly and the severe form of it rarely survives infancy because of the associated brain tissue (corpus callosum agenesis) deformity. Surgical correction can be challenging especially when it is associated with premaxilla agenesis and absence of columella and nasal septum.Materials/Method: A review of presentation and management of five patients with median cleft of upper lip and the discussion of relevant literature.Result: Four of the cases were adult. Repair of defects were carried out by Burrow’s procedure, inverted V excision technique combined with sub-periosteal undermining at labio-buccal sulci. Effective mobilization of labial flaps on both sides ensured good apposition, but the absence of columella and nasal septum remains a major challenge in reconstruction of the defect.Conclusion: Late presentation, attributed to ignorance and poverty remains a concern in management; apart from ignorance and poverty, shortage of specialists and facilities for craniofacial surgery in Northern Nigeria may also contribute to their late presentation. Multiple surgical interventions are also not usually attractive to the patients hence result of repair are modest.
