ABSTRACT
Like languages, facial features have been linked to ethnicities. Basically, nasal index is ratio of nasal breadth to nasal length, which varies greatly among different anthropometric groups and climate regions. Aim: to investigate sexual dimorphic characterization in nasal parameters of the Ikwo population in South-east, Nigeria. MATERIALS AND METHODS: The study recruited 250 Ikwo samples (males = 130, females = 120), after ethical approval gotten from University Research Committee and informed consents signed by the participants. Nasal length, width and indices were measured. RESULTS: Age and nasal indices appeared positively correlated but with weak R 2 Adjusted value (Age = 146 + 1.91â× Nasal indices, 35%). Also, sex and nasal indices were positive and very strong adjusted level (NI = 61+0.24â× Male and 61 + 0.084â× Female, and 82%). CONCLUSION: The mean nasal indices for both sexes in Ikwo population belong to platyrrhine nose classification, with predictive power that can be helpful in forensic science, craniofacial surgery, neurosurgery and developmental biology.

The right lung has three lobes and two fissures while the left lung has two lobes and one fissure. During a routine dissection we observed a variant complete fissure and three incomplete fissures in the right lung while the left lung presented with a variant transverse fissure separating the superior lingual and anterior bronchopulmonary segments. In the right lung, the incomplete fissures lie between the apical and posterior bronchopulmonary segments; medial and lateral bronchopulmonary segments; apical and basal bronchopulmonary segments. The complete variant fissure separates the medial basal bronchopulmonary segment from the remaining basal segments. Such variant fissures and lobes are clinically important in cases of lobotomy.
