BENIGN PAROXYSMAL POSITIONAL VERTIGO: AN UNUSUAL COMPLICATION OF RHINOPLASTY

Comparisons of Auditory and Vestibular Functions After Septorhinoplasty Performed with the Micro-compass Saw Technique and the Classical Technique

AIM

To evaluate hearing and labyrinth functions following different osteotomy types (micro-compass saw, osteotome, and no osteotomy) performed in septorhinoplasty operations.

MATERIAL AND METHOD

The study included 74 patients operated between January 2020 and March 2022, separated into 3 groups: Group 1: 24 patients (16 females and 8 males): osteotome was used for the osteotomy; Group 2: 24 patients (12 females and 12 males): micro-saw was used for osteotomy; and Group 3: 26 patients (17 females and 9 males): open technique septoplasty with no osteotomy. At 1 day before and 1 week after the operation, all the patients underwent audiological examination, tympanometry, vestibular evoked myogenic potentials (c-VEMP), video head impulse test (v-HIT), videonystagmography (VNG), and distortion product otoacoustic emission (DPOAE) tests.

RESULTS

In the c-VEMP tests, significant differences were determined between the groups in respect of N1, P1, and N1-P1 latencies and N1-P1 amplitudes before and after the operation. In the v-HIT test, the change in right-side posterior gain postoperatively was statistically significant in the micro-saw group (p<0.05). The postoperative right lateral canal values were determined to be statistically significantly increased in the micro-saw group compared to the osteotome group (p<0.05).

CONCLUSION

This is the only study in the literature to have determined vestibular effects with the evaluation of such a wide range of techniques. Previous studies in the literature have found no effect of osteotomy technique on the balance and hearing systems. The results of this study demonstrated that the preoperative and postoperative difference between the osteotomy techniques had an effect on the balance system. The change in the balance tests following an operation with classic osteotomy shows a greater predisposition to benign positional vertigo. In this sense, the micro-saw can be considered safer.

Study on Size Estimation of Prosthesis in Rhinoplasty Based on Mechanical Test and Analysis

Rhinoplasty is a common plastic surgery. The determination of prosthesis size for rhinoplasty has long been dependent on the surgeon's experience. Some of the patients suffered from complications after the surgery. In this paper, we present a method for estimating the size of prosthesis in rhinoplasty. A nasal tension tester is designed and implemented. On the basis of the mechanical theory of Hyperelastic Materials, an algorithm for inverse calculation of material parameters is proposed; On the basis of the material parameters, an algorithm for estimating the safety range of nasal stretch is established. The nasal tension tester can obtain the nasal tension data without harming the subject. Our results show that different subjects generally have different nasal skin elasticity and tolerance to skin stretch. Therefore, the selection of prosthesis size for rhinoplasty should not be generalized, but should be tested and calculated separately for each subject. The results of this study are helpful for doctors to quantitatively understand the skin condition of the subject 's nose and the safe range of nasal stretch, based on which the determination of prosthesis size can be made for rhinoplasty.

New Therapeutic Maneuver for Horizontal Semicircular Canal Cupulolithiasis: A Prospective Randomized Trial

Background: There are debates on whether mastoid oscillation has any benefit or harm in treating horizontal semicircular canal (HSCC) cupulolithiasis. The goal of this study was to investigate the therapeutic effects of the new maneuver using only inertia and gravity and compare it with the previously reported cupulolith repositioning maneuver using mastoid vibration (CuRM). Methods: We enrolled 57 patients diagnosed with HSCC cupulolithiasis. Patients were randomly allocated to the previously reported CuRM or the new maneuver (briefly, 30° head rotation to the affected side and thereafter bidirectional side-lying) using simply inertia and gravity, and their immediate and short-term effects were evaluated. Results: The immediate success rate did not differ significantly between the CuRM (8 of 22, 36.4%) and the new maneuver (10 of 35, 28.6%) groups (p = 0.538, Pearson’s chi-square test). The late resolution rates at the first follow-up of the CuRM (75%, 9 of 12) and new maneuver groups (82.6%, 19 of 23) were very high, and there was no statistical difference between them (p = 0.670, Fisher’s exact test). Conclusions: This study showed that the new maneuver was effective for treating HSCC cupulolithiasis with an immediate success rate of 28.6% (10 of 35). Although it did not show better results than the existing maneuver using vibration, there was no statistical difference. Considering the debate on the effectiveness of oscillation, we believe our new maneuver is a conservative alternative that uses only inertia and gravity, and it can be easily performed in clinics where oscillation equipment is not available.

Potential Risk of Benign Paroxysmal Positional Vertigo Due To Traumatic Effect of Osteotomy in Septorhinoplasty Patients

PURPOSE

We investigated the effect of osteotomy on the vestibular system in septorhinoplasty patients and determined the potential risk of benign paroxysmal positional vertigo (BPPV) in these patients.

PATIENTS AND METHODS

In the present prospective study, 47 primary septorhinoplasty patients were evaluated as the study group and 50 septoplasty patients as the control group. Osteotomy was performed in all septorhinoplasty patients. No hammer and osteotomes were used in the control group. All patients underwent static balance tests (tandem stance test, 1-leg standing test, and Romberg test), dynamic balance tests (tandem walking test and Fukuda test), positional balance tests (Dix-Hallpike test and supine roll test), head impulse test, and the adult dizziness handicap inventory (ADHI) preoperatively and during the first postoperative week.

RESULTS

No significant differences were found between the 2 groups in terms of the static balance tests, dynamic balance tests, positional balance tests, or head impulse test results. The postoperative ADHI scores were significantly worse in the septorhinoplasty patient group than in the control group. Posterior semicircular canal BPPV was observed in 2 patients in the septorhinoplasty group but none in the control group.

CONCLUSIONS

BPPV is one of the possible early postoperative complications of rhinoplasty. In patients with vertigo after rhinoplasty, surgeons should evaluate the semicircular canals using the Dix-Hallpike and supine roll tests. To avoid the traumatic effect of osteotomy reflected on the inner ear, attention should be given to the applied force, and sharp osteotomes should be used.

Effects of Rhinoplasty on Labyrinthine Function

BACKGROUND

Rhinoplasty is a common surgical procedure that is requested and accepted by patients for cosmetic and functional reasons. Osteotomies are performed on nasal bone, maxillary crest, or vomer to fix the deviations of the nasal dorsum or septum. During the percussion of the osteotomes with the surgical mallet, the vibration energy diffuses to the cranium. Auditory and vestibular systems may be affected by these vibrations.

OBJECTIVES

To assess the effects of rhinoplasty, in which osteotomies were performed using a hammer, on the audiovestibular system.

METHODS

Thirty adults who underwent rhinoplasty were included in the study group. Ten age and gender matched adults who had nasal surgery without surgical mallet or osteotome served as the control group. The patients in both groups were assessed using pure tone audiometry, tympanometry, distortion product otoacoustic emission testing, and vestibular-evoked myogenic potential, as well as video head impulse tests (vHIT) before the operation and 1 week after the operation.

RESULTS

On auditory assessment, there was no significant difference between the study and control groups regarding pure tone thresholds at frequencies of 250 Hz to 8 kHz (P > 0.05) as well as otoacoustic emissions. The vestibular assessment performed by using vestibular-evoked myogenic potential and vHIT did not reveal a statistically significant difference between the groups, before surgery or after surgery (P > 0.05).

CONCLUSIONS

Rhinoplasty appears to be a safe operation in terms of audiovestibular functions, and osteotomy, in which a hammer is usually used, does not have an impact on hearing or balance functions of the ear.

Unintentional Complications After Uneventful Rhinoplasty Operations: Case Reports and a Review of the Literature

INTRODUCTION

No surgical procedure is free of complications; however, some of these complications are unintentional. Plastic surgeons may be unfamiliar with certain complications after rhinoplasty operations. In this study, we aimed to present four unintentional complications that have occurred in our patients and review the literature related to these complications.

MATERIALS AND METHODS

In this study, we conducted a review of 1400 patients who were operated on from 2007 to 2015. The medical recordings of all patients were investigated. Four patients with unintentional complications after rhinoplasty operations are presented and the related literature was reviewed.

CASES

Cases 1 and 2: These patients included a 26-year-old woman and a 30-year-old man who developed herpes simplex virus (HSV) infections after a primary septorhinoplasty. Case 3: This was a 25-year-old woman who developed periorbital emphysema after a primary rhinoplasty operation. Case 4: This was a 22-year-old woman who developed a second-degree burn on the nasal dorsum. All patients healed without sequel or scars.

DISCUSSION

Many unexpected complications have been reported in the literature. Some of these complications include bleeding disorders, allergic reactions, dermatitis, visual loss, gastric bleeding, benign paroxysmal positional vertigo, false aneurysm after rhinoplasty, pneumocephalus, Tapia's syndrome, cavernous sinus syndrome, and skin reactions to prolene.

CONCLUSION

Meticulous patient histories, consistent surgical routines, careful radiologic examinations, and frequent patient visits can help surgeons control these types of complications.

Symptom Resolution Rates of Posttraumatic versus Nontraumatic Benign Paroxysmal Positional Vertigo

Objective

To determine the rate of symptom resolution in patients with posttraumatic benign paroxysmal positional vertigo (BPPV) and to determine if it differs from resolution rates in patients with BPPV and without a history of head trauma.

Data Sources

Systematic review of the literature was performed using Medline, EMBASE, and Cochrane databases. English and French articles meeting inclusion criteria and published between 1946 and October 2014 were included.

Review Methods

Data were independently extracted from the articles by 2 reviewers using data collection forms developed a priori. Inclusion and exclusion criteria were decided a priori. Studies were included if they reported on at least 1 case of posttraumatic BPPV (t-BPPV), reported on outcomes of all patients with t-BPPV, had a clearly defined inception point, and provided a clear diagnosis of BPPV (defined a priori by reviewers).

Results

A total of 3017 titles, 362 abstracts, and 67 articles were reviewed, from which 16 articles met inclusion criteria and underwent data extraction. There were a total of 207 patients with posttraumatic BPPV identified. Among the 207 patients, 151 (73%) had resolution of symptoms. The T-BPPV patients may have more multi-canal involvement and may require more repositioning maneuvers for resolution compared to patients with nontraumatic BPPV.

Conclusions

Available evidence does not support the notion that symptom resolution rates in patients with posttraumatic BPPV are worse than those with nontraumatic BPPV. However, well-designed studies with adequate cohorts are lacking. Additional well-executed studies are needed to confirm this lack of difference in resolution rates.

Benign paroxysmal positional vertigo during lateral window sinus lift procedure: a case report and review

PURPOSE

Benign paroxysmal positional vertigo (BPPV) is a possible and well-documented complication after the osteotome internal sinus lift technique. But we report a case of unexpected BPPV complication after direct sinus lift by lateral approach for implant placement that was not reported till date.

METHODS

A 30-year-old woman had undergone direct sinus lift procedure by lateral window technique to replace her missing right molar with dental implant. The patient suffered with intense vertigo with nausea, vomiting, and aggravated when she changed the position of her head towards right immediately after procedure and was diagnosed with BPPV after the referral.

CONCLUSION

We assume that prolonged hyperextended head position of iatrogenic origin can be the reason, in this case, for BPPV after direct lateral sinus lift procedure. There is also a possibility that the temporal relationship with the surgical area and surgical action by rotating tools during window preparation are also contributing factors.

Benign Paroxysmal Positional Vertigo: An Integrated Perspective

Benign paroxysmal positional vertigo (BPPV), the most common cause of dizziness, occurs in all age groups. It presents with vertigo on head movement, but in older patients presentation may be typical and thus accounting for a low recognition rate in the primary care setting. It may be recurrent in up to 50% of cases. BPPV is associated with displacement of fragments of utricular otoconia into the semicircular canals, most commonly the posterior semicircular canal. Otoconia are composed of otoconin and otolin forming the organic matrix on which calcium carbonate mineralizes. Otoconia may fragment with trauma, age, or changes in the physiology of endolymph (e.g., pH and calcium concentration). Presentation varied because otoconia fragments can be displaced into any of the semicircular canals on either (or both) side and may be free floating (canalolithiasis) or attached to the cupula (cupulolithiasis). Most cases of BPPV are idiopathic, but head trauma, otologic disorders, and systemic disease appear to be contributory in a subset. Positional maneuvers are used to diagnose and treat the majority of cases. In rare intractable cases surgical management may be considered. A strong association with osteoporosis suggests that idiopathic BPPV may have diagnostic and management implications beyond that of a purely otologic condition.

Self-limiting benign paroxysmal positional vertigo following use of whole-body vibration training plate

Objective:

We describe a case of benign paroxysmal positional vertigo which occurred after use of a whole-body vibration training plate.

Method:

Case report and literature review concerning the secondary causes of benign paroxysmal positional vertigo and the physiological effects of whole-body vibration training plates.

Results:

A 44-year-old woman was referred with classic symptoms of benign paroxysmal positional vertigo following use of a whole-body vibration training plate, a popular form of fitness equipment widely used in sports, rehabilitation and beauty treatments. The condition resolved spontaneously after several days. There have been reports of negative side effects in users of this equipment, such as dizziness, headache and a sensation of imbalance; however, there have been no reported cases involving vertigo. Based on a literature review, this equipment may cause side effects, including vertigo, by generating forces that can increase the original amplitude of internal organs, which may potentially cause labyrinthine trauma or dislocation of otoconia, leading to benign paroxysmal positional vertigo.

Conclusions:

We suggest that whole-body vibration training plates may potentially induce benign paroxysmal positional vertigo. Manufacturers may need to make users of this equipment aware of this risk, and remind them to use it with caution.
