Fabricating a partial nasal prosthesis with a custom nasal dilator design.

Patients undergoing partial rhinectomy with limited size may have the major portion of the nasal structure preserved. However, the fibrosis or scar formation after the surgery may cause distortion of remaining tissues, followed by nasal airway obstruction. By physically expanding an affected nostril during the impression and using digital technology to design a custom flexible internal nasal dilator, embedded in the medical grade silicone during processing, a partial nasal prosthesis with airway-maintaining purpose can be fabricated to improve quality of life both esthetically and functionally.

Using digital technology to create a custom esthetic bandage for patients after rhinectomy.

Patients undergoing partial or total rhinectomy surgeries are left with a lifelong facial defect that poses psychosocial and functional challenges. The extended postoperative healing period after rhinectomy can delay the timely restoration of a patient's nose by definitive prosthesis when conventional impression methods are used. The treatment workflow for fabricating a custom esthetic nasal bandage with the use of digital technology is introduced to avoid the conventional preoperative impression, as well as to allow for immediate delivery at the postoperative follow-up visit.

Sectional impressions and simplified folding complete denture for severe microstomia.

A patient presenting with severe microstomia (PDI Class IV) was unable to insert a maxillary complete denture. Sectional final impressions were made using two impression materials and an interlocking custom tray. A folding record base was used for maxillomandibular relationship records. A novel folding maxillary denture with a custom hinge and plunger attachment to lock the denture in the open position was fabricated. The patient was able to insert the collapsed denture, open it intraorally, and enjoy successful masticatory function.

Prosthetic Rehabilitation via Silicone Nasal Prosthesis with Internal Alar Support Following Partial Rhinectomy: A Short Communication.

PURPOSE: To describe prosthetic rehabilitation following partial rhinectomy with use of a novel retentive internal nasal keeper piece. MATERIALS AND METHODS: The reported novel nasal keeper piece engaged the intact inferior portions of the major alar cartilages and the alar fibrofatty tissues to aid in retention of the prosthesis. RESULTS/CONCLUSION: The reported prosthesis utilizes a retentive mechanism not previously reported in the literature to maximize function and esthetics.
