Researcher Hani Salah Salem Al‑Nahdi was awarded a Master’s Degree in Orthodontics for his thesis titled: Evaluation of Malocclusion Types and Craniofacial Morphology in Adult Patients with Nasal Septum Deviation, which was submitted to the Department of Orthodontics, Faculty of Dentistry– Sana’a University. The MA defense was held on Thursday, October 22, 2026.
The MA Viva-voce Committee, which was formed based on a resolution issued by the Graduate Studies and Scientific Research Council, consisted of the following:
·Prof. Yasser Thabet – Ibb University – External Examiner and Chair
·Assoc. Prof. Fouad Al‑Muttarib – Sana’a University – Main Supervisor and Committee Member
·Prof. Na’ila Al‑Mujahid – Sana’a University – Internal Examiner and Committee Member.
The study aimed to evaluate the relationship between the degree of nasal septum deviation and patterns of malocclusion and craniofacial morphology in adults, through a cross‑sectional analysis of a group of patients.
It employed the Mladina classification for nasal septum deviation and cephalometric analysis of reconstructed CT images.
The findings of the study showed that Class II malocclusion was the most prevalent among adult patients with nasal septum deviation, while the vertical divergent facial pattern was the most common craniofacial type. Statistical analysis revealed a significant relationship between the degree of septum deviation and both malocclusion type and vertical facial morphology, as well as the position of the maxilla. However, no significant correlation was found between septum deviation and mandibular position.
The study concluded that there is a correlation between the severity of nasal septum deviation and certain malocclusion patterns and craniofacial characteristics in adults, underscoring the importance of considering this relationship in orthodontic diagnosis and treatment planning.
The study recommended fostering collaboration and joint assessment between orthodontists and otolaryngologists (ENT specialists), and incorporating an examination of the nasal septum into the orthodontic diagnostic process for cases where it is indicated.
The thesis defense was attended by faculty members, researchers, students, and interested participants as well as the researcher's colleagues and family members.
