Surgical outcomes of myringoplasty using platelet-rich plasma and evaluation of the outcome-associated factors.

Objective: Tympanic membrane perforations must be closed with surgery; however, most surgical procedures are considerably invasive in nature. The aim of this study was to evaluate the outcomes of minimally invasive myringoplasty using platelet-rich plasma (PRP) and an atelocollagen sponge for closure of chronic tympanic membrane perforations, as well as to identify the factors affecting the surgical outcome.

Methods: The records of 118 patients who underwent surgical closure of chronic tympanic membrane perforation at an ear-nose-throat clinic were reviewed retrospectively.

Impaired visual suppression of manually rotated vestibuloocular reflex indicates the need of further evaluation by MRI and MRA in patients with vertigo.

Objective: MRI and MRA are accepted as valuable methods for diagnosing vertigo, although they are costly and time-consuming. Thus, some indicator of the necessity of a detailed evaluation by MRI and MRA is desirable.

Study Design And Setting: To assess the usefulness of an impairment of the visual suppression (VS) as an indicator, the relation between abnormal findings on MRI and/or MRA and impairment of the VS of manually rotated vestibuloocular reflex (VOR) was retrospectively examined in 40 consecutive patients suffering from vertigo.

[Clinical evaluation of congenital cholesteatoma of the middle ear].

We conducted a retrospective study to identify the clinical features and surgical observations of congenital cholesteatoma. Sixty patients were diagnosed and underwent surgery for congenital cholesteatoma between April 1987 and May 2002. All diagnoses were made on the basis of two operative findings: 1.

Hyperviscoelasticity of epipharyngeal mucus may induce globus pharyngis.

Detailed observation reveals a lump of translucent sticky mucus standing in the epipharynx of most globus patients, suggesting that the mucus adherent to the epipharynx causes a globus sensation. The epipharyngeal mucus of 70 consecutive globus patients was sampled via the nasal cavity. Fucose and sialic acid, the determinants of the viscoelasticity of mucus, were measured.

Endoscopic trans-nasal-vestibular approach to the maxillary sinus--application for mucoceles of the maxillary sinus.

Endoscopic endonasal surgery has been applied to the treatment of paranasal mucoceles. The approach is, however, hard to be adopted for maxillary mucoceles when the cyst is situated in the anterior and/or lateral portion of the maxillary sinus, has a thick bony lateral wall of the inferior nasal meatus, and when the patients develop compartmentalized cysts following facial trauma or sinus operation. We devised an endoscopic approach via the vestibule of the nose to reach any part of the maxillary sinus and applied it for the treatment of postoperative maxillary mucoceles, which could not be opened following the usual endoscopic approach with favorable outcomes.
